NOTICE OF ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS AND MANAGEMENT INFORMATION CIRCULAR EXHIBIT 1 MANAGEMENT PROXY CIRCULAR RELATING TO AN ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS OF DESERT SUN MINING CORP. CONCERNING THE PROPOSED BUSINESS COMBINATION OF DESERT SUN MINING CORP. AND YAMANA GOLD INC. March 1, 2006 March 1, 2006 Dear Desert Sun Shareholder: The Board of Directors cordially invites you to attend an annual and special meeting (the "Meeting") of shareholders of Desert Sun Mining Corp. ("Desert Sun") to be held at The Fairmont Royal York, Tudor Room 7-8, 100 Front Street West, Toronto, Ontario, M5J 1E3, on Friday, March 31, 2006 at 10:30 a.m. (Toronto time). At the Meeting, in addition to the election of directors and the appointment of auditors, you will be asked to approve a special resolution (the "Arrangement Resolution"), the full text of which is reproduced in Exhibit F of the management proxy circular (the "Proxy Circular") that accompanies this letter, in respect of a proposed business combination (the "Combination") by way of a plan of arrangement (the "Arrangement") involving Desert Sun and Yamana Gold Inc. ("Yamana"). Pursuant to an arrangement agreement dated as of February 22, 2006 (the "Arrangement Agreement") among Desert Sun, Yamana and 6524338 Canada Inc. ("Yamana Subco"), a wholly-owned subsidiary of Yamana, Desert Sun and Yamana have agreed to complete the Arrangement pursuant to which Desert Sun will amalgamate with Yamana Subco. As a result of the Arrangement, Desert Sun Shareholders will receive 0.6 of a common share of Yamana (the "Yamana Shares") in exchange for each common share of Desert Sun (the "Desert Sun Shares") and the combined company will be a wholly-owned subsidiary of Yamana. Based on the number of Yamana Shares outstanding on February 28, 2006 (being 199,238,320), existing holders of Desert Sun Shares will hold approximately 24% of the Yamana Shares upon completion of the Arrangement, assuming no exercise of Desert Sun or Yamana options or warrants outstanding subsequent to February 28, 2006. Yamana is a Canadian gold producer with significant gold production, gold and copper-gold development stage properties, exploration properties and land positions in all major mineral areas in Brazil. With its recent acquisition of RNC Gold Inc., Yamana also owns two producing mines in Central America. Yamana expects to produce gold at intermediate company production levels during 2006 in addition to significant copper production by 2007. Management of Yamana plans to build on this base through the advancement of its exploration properties and by targeting other gold consolidation opportunities in Brazil and elsewhere in Latin America. The Combination offers Desert Sun Shareholders an attractive premium per Desert Sun Share of approximately 24% based on the ten-day weighted average trading prices of Desert Sun and Yamana Shares for the period ending on February 21, 2006, the date prior to the date on which the transaction was announced. Through the combined company, current Desert Sun Shareholders will be able to participate in a gold producer with significant growth potential, will be able to mitigate the risks inherent with a one-mine company and will benefit from an enhanced management team with significant operating experience. The approval of the Arrangement Resolution requires an affirmative vote of not less than two-thirds of the votes cast by the Desert Sun Shareholders, and a simple majority of disinterested shareholders of Desert Sun, who vote in respect of the Arrangement Resolution, in person or by proxy, at the Meeting. The Board of Directors has determined that the Arrangement is in the best interests of Desert Sun and fair to Desert Sun Shareholders. The Board of Directors came to this determination based on, among other things: the opinion of the financial advisor to the Board of Directors, Sprott Securities Inc., that as of the date of such opinion, the Arrangement is fair, from a financial point of view, to Desert Sun Shareholders; the recommendation of a special committee of directors formed to consider the Arrangement; and the opinion of the financial advisor to the special committee of directors, GMP Securities L.P., that as of the date of such opinion, the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders. THE BOARD OF DIRECTORS OF DESERT SUN HAS UNANIMOUSLY APPROVED THE ARRANGEMENT AND THE TERMS OF THE ARRANGEMENT AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOUR OF THE ARRANGEMENT RESOLUTION AT THE MEETING FOR THE REASONS SET FORTH IN THE ATTACHED PROXY CIRCULAR. It is important that your Desert Sun Shares be represented at the Meeting. Whether or not you are able to attend, we urge you to complete the enclosed form of proxy and return it by noon, Toronto time, on March 29, 2006 to Equity Transfer Services Inc., at 120 Adelaide Street West, Suite 420, Toronto, Ontario, M5H 4C3, or by fax (Attention: Proxy Department) at (416) 361-0470.

If you require any assistance in completing your proxy, please call Kingsdale Shareholder Services Inc. toll free at 1-866-588-6864. Included with this letter, in addition to the form of proxy and the letter of transmittal referred to below, is a Notice of Meeting and the Proxy Circular.

You will not actually receive your Yamana Shares until after the Arrangement has been completed and you have returned your properly completed documents, including the letter of transmittal and your certificates representing Desert Sun Shares. If the Desert Sun Shareholders approve the Arrangement Resolution, it is anticipated that the Arrangement will be completed at the beginning of April 2006. On behalf of Desert Sun, I would like to thank all shareholders for their continuing support.

Statements.............................................J-1 NOTICE TO SHAREHOLDERS IN THE UNITED STATES This solicitation of proxies and the transactions contemplated in this Proxy Circular are made in the United States for the securities of a Canadian company in accordance with Canadian corporate and securities laws. The Yamana Shares issued pursuant to the Arrangement (including those to be issued upon the exercise of Desert Sun Options and Desert Sun Warrants) have not been registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act") and will instead be issued in reliance on an exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) of the U.S. Securities Act. The solicitation of proxies made in connection with this Proxy Circular is not subject to the requirements of Section 14(a) of the United States Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act"). Accordingly, this Proxy Circular has been prepared in accordance with disclosure requirements applicable in Canada. Security holders in the United States should be aware that such requirements are different from those of the United States applicable to registration statements under the U.S. Securities Act and to proxy statements under the U.S. Exchange Act. The financial statements (including the pro forma financial statements) of Desert Sun, Yamana and RNC Gold Inc. included or incorporated by reference in this Proxy Circular have been prepared in accordance with Canadian generally accepted accounting principles and are subject to Canadian auditing and auditor independence standards, and thus may not be comparable in all respects to financial statements of United States companies. See Exhibit A -- "Desert Sun Mining Corp. -- Non-GAAP Measures" and Exhibit B -- "Yamana Gold Inc. -- Non GAAP Measures". This Proxy Circular uses the terms "measured", "indicated" and "inferred" mineral resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize these terms. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable. U.S. shareholders should be aware that the disposition of Desert Sun Shares pursuant to the Arrangement might have tax consequences both in Canada and in the United States, which may not be described fully herein. See "Certain Tax Considerations to Desert Sun Shareholders -- Certain Canadian Federal Income Tax Considerations -- Desert Sun Shareholders Not Resident in Canada" and "Certain Tax Considerations to Desert Sun Shareholders -- Certain United States Federal Income Tax Consequences" in this Proxy Circular. Shareholders are encouraged to consult their own tax advisers. The enforcement by investors of civil liabilities under the United States securities laws may be affected adversely by the fact that Desert Sun, Yamana and Yamana Subco are incorporated and organized under the laws of Canada, that most of their respective officers and directors are residents of Canada and that all of the assets of Desert Sun, Yamana and Yamana Subco are located outside of the United States. You may not be able to sue a Canadian company or its officers or directors in a Canadian court for violations of United States securities laws. It may be difficult to enforce in Canada a judgement of a United States court that is based on a violation of U.S. securities laws. THE SECURITIES TO BE ISSUED PURSUANT TO THIS TRANSACTION HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES REGULATORY AUTHORITY NOR HAS THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES REGULATORY AUTHORITY PASSED UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. 1 REPORTING CURRENCY In this document, unless otherwise specified, all references to "dollars" or "$" are to Canadian dollars. On February 28, 2006, the noon rate in Toronto, as reported by the Bank of Canada, was $1.1380 for each US$1.00. The closing, high, low and average exchange rates for the U.S. dollar in terms of Canadian dollars for the years ended December 31, 2005, 2004 and 2003, as reported by the Bank of Canada, were as follows: Year Ended December 31, 2005 2004 2003 Closing.......................................... $1.16 $1.20 $1.29 High............................................. 1.27 1.39 1.57 Low.............................................. 1.14 1.17 1.29 Average(1)....................................... 1.21 1.30 1.40 ----------- (1) Source: Bank of Canada -- calculated as an average of the daily noon rates for each period. FORWARD-LOOKING STATEMENTS This Proxy Circular contains "forward-looking statements", within the meaning of the United States Private Securities Litigation Reform Act of 1995, and "forward-looking information" under similar Canadian legislation, concerning the business, operations and financial performance and condition of each of Yamana and Desert Sun. Forward-looking statements and forward-looking information include, but are not limited to, statements with respect to estimated production, synergies and financial impact of the proposed transaction; the benefits of the proposed transaction and the development potential of Yamana's and Desert Sun's properties; the future price of gold and copper; the estimation of mineral reserves and mineral resources; the realization of mineral reserve estimates; the timing and amount of estimated future production; costs of production; capital expenditures; success of exploration activities; permitting time lines and permitting, mining or processing issues; currency exchange rate fluctuations; government regulation of mining operations; environmental risks; unanticipated reclamation expenses; title disputes or claims; litigation liabilities; and limitations on insurance coverage. Generally, forward-looking statements and forward-looking information can be identified by the use of forward-looking terminology such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved". Forward-looking statements and forward-looking information are based on the opinions and estimates of management as of the date such statements are made, and they are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of Yamana and Desert Sun to be materially different from those expressed or implied by such forward-looking statements or forward-looking information, including but not limited to risks related to: unexpected events during construction, expansion and start-up; variations in ore grade, tonnes mined, crushed or milled; variations in relative amounts of refractory, non-refractory and transition ores; delay or failure to receive board or government approvals; timing and availability of external financing on acceptable terms; the businesses of Yamana and Desert Sun not being integrated successfully or such integration proving more difficult, time consuming or costly than expected; not realizing on the anticipated benefits from the Arrangement and all related transactions or not realizing on such anticipated benefits within the expected time frame; risks related to international operations; actual results of current exploration activities; actual results of current reclamation activities; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; future prices of gold and copper; possible variations in ore reserves, grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in the completion of development or construction activities, as well as those factors discussed in or referred to in the current annual Management's Discussion and Analysis and current Annual Information Form of each 2 of Yamana and Desert Sun each filed with the securities regulatory authorities in Canada and available at www.sedar.com, and Yamana's Annual Report on Form 40-F and Desert Sun's Annual Report on Form 40-F filed with the United States Securities and Exchange Commission. Although management of each of Desert Sun and Yamana has attempted to identify important factors that could cause actual results to differ materially from those contained in forward- looking statements or forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward- looking statements and forward-looking information. Neither Desert Sun nor Yamana undertakes to update any forward-looking statements or forward-looking information that are incorporated by reference herein, except in accordance with applicable securities laws. Readers are advised that National Instrument 43-101 of the Canadian Securities Administrators requires that each category of mineral reserves and mineral resources be reported separately. Readers should refer to the respective Annual Information Forms of Desert Sun and Yamana, each for the year ended December 31, 2004, and other continuous disclosure documents filed by each of Desert Sun and Yamana since January 1, 2005, available at www.sedar.com, for this detailed information, which is subject to the qualifications and notes set forth therein. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Readers should refer to the respective Annual Information Forms of Yamana, Desert Sun and RNC Gold Inc, each for the year ended December 31, 2004, and other continuous disclosure documents filed by each of Yamana, Desert Sun and RNC Gold Inc. since January 1, 2005 available at www.sedar.com, for further information relating to the mineral resources and mineral reserves of Yamana, Desert Sun and RNC Gold Inc.

No person has been authorized to give information or to make any representations in connection with the transactions other than those contained in this Proxy Circular and, if given or made, any such information or representations should be considered as not having been authorized by Desert Sun, Yamana or Yamana Subco. This Proxy Circular does not constitute an offer to sell, or a solicitation of an offer to acquire, any securities, or the solicitation of a proxy, by any person in any jurisdiction in which such an offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such an offer or solicitation. Shareholders should not construe the contents of this Proxy Circular as legal, tax or financial advice and should consult with their own professional advisors as to the relevant legal, tax, financial or other matters in connection herewith.

Certain capitalized words and terms used in this summary are defined in the Glossary of Terms. This summary is qualified in its entirety by, and should be read together with, the detailed information and financial data and statements contained or referred to elsewhere or incorporated by reference in this Proxy Circular including the Exhibits hereto. THE MEETING DATE, TIME AND PLACE OF MEETING The Meeting will be held on Friday, March 31, 2006 commencing at 10:30 a.m. (Toronto time) at The Fairmont Royal York, Tudor Room 7-8, 100 Front Street West, Toronto, Ontario, M5J 1E3. RECORD DATE At the close of business on the Record Date, there were 105,164,482 Desert Sun Shares outstanding. Desert Sun Shareholders of record at the close of business on the Record Date are entitled to attend, and to vote at, the Meeting. MATTERS TO BE CONSIDERED The Meeting will be constituted as an annual and special meeting of Desert Sun Shareholders. The Desert Sun Shareholders will be asked to consider and vote upon: (i) the election of directors of Desert Sun for the ensuing year; (ii) the appointment of auditors of Desert Sun for the ensuing year and the authorization of the directors to fix their remuneration; (iii) pursuant to the Interim Order, the Arrangement Resolution; and (iv) such other matters as may properly come before the Meeting. DESERT SUN SHAREHOLDER APPROVAL In order for the Arrangement to be effected, the Arrangement Resolution must be approved by (i) an affirmative vote of not less than two-thirds of the votes cast thereon by Desert Sun Shareholders at the Meeting, in person or by proxy, and (ii) an affirmative vote of a majority of the votes cast thereon by disinterested Desert Sun Shareholders at the Meeting, in person or by proxy. INTERESTS OF CERTAIN PERSONS IN THE ARRANGEMENT Certain directors and/or officers of Desert Sun have interests in the Combination that are different than the interests of Desert Sun Shareholders generally. These interests relate primarily to certain benefits that are or may be triggered under consulting agreements of certain officers of Desert Sun in certain circumstances following a change of control of Desert Sun. See "Information Concerning the Meeting -- Interests of Certain Persons in the Arrangement". 4 THE COMBINATION Pursuant to the Arrangement Agreement, Desert Sun and Yamana have agreed to complete the Arrangement pursuant to which, among other things, Desert Sun will amalgamate with Yamana Subco, each Desert Sun Shareholder (other than a Registered Desert Sun Shareholder who exercises dissent rights) will be entitled to receive Yamana Shares in exchange for Desert Sun Shares held by such Desert Sun Shareholder on the basis of 0.6 Yamana Shares for each Desert Sun Share held by such Desert Sun Shareholder and Amalco will be wholly-owned by Yamana, all pursuant to the Plan of Arrangement. Upon completion of the Arrangement, each holder of a Desert Sun Warrant or a Desert Sun Option will be entitled to receive, upon subsequent exercise thereof, in accordance with the terms thereof, and shall accept in lieu of the number of Desert Sun Shares otherwise issuable upon such exercise, the number of Yamana Shares that such holder would have been entitled to receive as a result of the Arrangement if, immediately prior to the effective time of the Arrangement, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was previously entitled upon exercise. Upon completion of the Arrangement, former Desert Sun Shareholders will own approximately 24% of the outstanding Yamana Shares, on a non-diluted basis, and former Desert Sun securityholders will hold approximately 27.5% of the outstanding Yamana Shares, on a fully-diluted basis. See "The Combination". BENEFITS OF THE ARRANGEMENT The Board of Directors believes that the Combination will have the following benefits for Desert Sun Shareholders: 1. the Combination offers an attractive premium of approximately 24% to the weighted average trading prices of Desert Sun and Yamana for the ten day period ending on February 21, 2006, the date prior to the date on which the transaction was announced; 2. the combined company will be a significant gold producer with one of the largest production growth profiles; 3. the combined company will be well positioned for internal growth and have the financial strength and flexibility to take advantage of consolidation and acquisition opportunities in the gold mining industry; 4. the combined company will have interests in six producing gold operations, with estimated annualized gold production of approximately 450,000 gold equivalent ounces in 2006, making it one of the largest gold producers in Brazil; 5. as a result of the Combination, Desert Sun will mitigate the operational risks inherent in a one-mine company; 6. the combined company will have immediate and near-term production growth opportunities through the development of the Chapada mine and the Morro do Vento project; 7. the combined company expects to reduce expenses, including costs of production, based on the proximity of the Jacobina mine to Yamana's Fazenda Brasileiro and its ability to take advantage of general and administrative merger synergies; 5 8. the combined company will have a market capitalization of approximately $2.4 billion (based on the closing price of the Desert Sun Shares and the Yamana Shares on the TSX on February 22, 2006, the date that the Arrangement was announced), which will facilitate the addition of the securities of the combined company to gold indices and will enhance its ability to compete for world class projects; and 9. the combined company will have an experienced management team with significant operating experience. SPECIAL COMMITTEE REVIEW AND RECOMMENDATION OF THE BOARD OF DIRECTORS A Special Committee of the Board of Directors was formed to review the Combination and reported to the Board of Directors respecting its recommendations and conclusions. The Special Committee concluded that the Arrangement is fair to Desert Sun Shareholders and that the Combination is in the best interests of Desert Sun and Desert Sun Shareholders. Further, the Special Committee recommended that the Board of Directors proceed with the Arrangement. In reaching its conclusions and formulating its recommendations, the Special Committee considered the expected benefits from the Combination as well as a number of factors including: (a) information regarding Yamana, its assets and properties (see a summary of such information set forth in Exhibit B -- "Yamana Gold Inc."); (b) information regarding Yamana with respect to its historical and current financial condition, business and operations; (c) historical information regarding the market prices and trading information of the Desert Sun Shares and the Yamana Shares; (d) information regarding Yamana obtained by Desert Sun management from its due diligence review of Yamana and, in particular, technical information obtained during visits to Yamana properties; (e) Desert Sun management concluded that the significant opportunities for cost savings in Brazil that are expected to result from the Combination will not be available to third parties, hence, in their opinion, making it difficult for a third party to offer consideration in excess of what is offered under the Combination; (f) the anticipated size and market liquidity of the combined company, subsequent to the Arrangement; (g) that the Yamana Shares offered in connection with the Arrangement provide Desert Sun Shareholders with the opportunity to be shareholders of a larger, more diversified company; (h) Desert Sun Shareholders will retain their ability to benefit from the growth prospects represented by the combined company by receiving 0.6 of a Yamana Share for each Desert Sun Share held; (i) the Exchange Ratio implied a price of $5.57 per Desert Sun Share representing a premium of approximately 24% based on the volume-weighted-average trading prices of Yamana and Desert Sun for the ten-day period ending on February 21, 2006, the date prior to the date on which the Arrangement was announced; (j) the GMP Fairness Opinion and the Sprott Securities Fairness Opinion, which both concluded that the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders; (k) the Special Committee has relied on the fact that Sprott Securities had previously been retained as financial advisor to identify and approach potential third parties that demonstrated a real interest in pursuing a transaction at a price/consideration comparable to that offered pursuant to the Combination and that would be motivated and able to complete a transaction in a reasonable period of time; 6 (l) for Canadian federal income tax purposes, Desert Sun Shareholders who hold their Desert Sun Shares as capital property generally will be able to exchange their Desert Sun Shares for Yamana Shares under the Arrangement on a tax-deferred basis under the Tax Act (see "Certain Tax Considerations to Desert Sun Shareholders -- Certain Canadian Federal Income Tax Considerations"); (m) the view of the Desert Sun Board of Directors that the terms and conditions of the Arrangement Agreement, including the amount of the Termination Fee and the circumstances under which it is payable, do not prevent, or unreasonably deter, an unsolicited third party from proposing or making a Superior Proposal, provided that Desert Sun complies with the terms of the Arrangement Agreement; (n) the Arrangement Resolution must be approved by not less than two-thirds of the votes cast at the Meeting by Desert Sun Shareholders and a majority of the votes cast at the Meeting by disinterested Desert Sun Shareholders; (o) the Arrangement requires approval of the Court, which will consider, among other things, the fairness of the Arrangement to Desert Sun Shareholders; (p) the risks associated with the completion of the Combination, and the risks associated with not completing the Combination; and (q) under the Arrangement, Registered Desert Sun Shareholders will have dissent rights. The Special Committee also considered current industry, economic and market conditions and trends as well as the reasons set forth under "The Combination -- Benefits for the Combination". After considering the report of the Special Committee, the Board of Directors adopted the Special Committee's recommendation, concluded that the Arrangement and the terms of the Arrangement Agreement are fair to Desert Sun Shareholders and authorized the entry by Desert Sun into the Arrangement Agreement and all related agreements. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT DESERT SUN SHAREHOLDERS VOTE IN FAVOUR OF THE ARRANGEMENT RESOLUTION. SPROTT SECURITIES FAIRNESS OPINION Desert Sun engaged Sprott Securities Inc. ("Sprott Securities") as its financial advisor as of January 27, 2006. As part of its engagement, Sprott Securities was asked by the Board of Directors to, among other things, consider the proposed Combination and provide its opinion as to the fairness of the Arrangement, from a financial point of view, to Desert Sun Shareholders. On February 20, 2006, Sprott Securities provided in writing to the board of directors its opinion, that as of that date, based upon and subject to the considerations described therein, the Arrangement is fair, from a financial point of view, to Desert Sun Shareholders. Under the terms of the Sprott Securities Engagement Letter, Desert Sun has agreed to pay Sprott Securities an advisory fee equal to 0.5% of the value attributed to Desert Sun in the Arrangement, which is payable upon its completion. Desert Sun Shareholders are encouraged to read the full text of the Sprott Securities Fairness Opinion, which sets forth, among other things, assumptions made, information reviewed, matters considered and limitations on the scope of the review undertaken by Sprott Securities in rendering the Sprott Securities Fairness Opinion. The Sprott Securities Fairness Opinion is attached as Exhibit C to this Proxy Circular. GMP FAIRNESS OPINION The Special Committee engaged GMP Securities L.P. ("GMP") as its financial advisor as of February 13, 2006. As part of its engagement, GMP was asked by the Special Committee to, among other things, consider the proposed Combination and provide its opinion as to the fairness of the Arrangement, from a financial point of view, to Desert Sun 7 Shareholders. On February 20, 2006, GMP provided in writing to the board of directors its opinion, that as of that date, based upon and subject to the considerations described therein, the Arrangement is fair, from a financial point of view, to Desert Sun Shareholders. Desert Sun Shareholders are encouraged to read the full text of the GMP Fairness Opinion, which sets forth, among other things, information reviewed, matters considered and limitations on the scope of the review undertaken by GMP in rendering the GMP Fairness Opinion. The GMP Fairness Opinion is attached as Exhibit D to this Proxy Circular.

Desert Sun Options shall continue to be governed by and be subject to the terms of the Desert Sun Stock Option Plan and applicable agreement thereunder except to the extent that a Desert Sun Option will expire on the earlier of the expiry date for such option and six months after the Effective Date (instead of in ninety days as provided in the Stock Option Plan) if the holder thereof ceases to be an employee, consultant or director of Desert Sun as of the Effective Date and does not become an employee, consultant or director of Yamana or a material subsidiary thereof on that date; (vi) each Yamana Subco Share will be exchanged for one Amalco Share; (vii) Desert Sun Shareholders (other than Dissenting Shareholders) will become shareholders of Yamana, a corporation governed by the CBCA; and (viii) Amalco will be a wholly-owned subsidiary of Yamana.

CONDITIONS TO THE COMBINATION The Arrangement is subject to a number of mutual conditions, which can only be waived by both Desert Sun and Yamana, including, among others, (i) the Interim Order shall have been granted and not amended in a manner unacceptable to Yamana or Desert Sun; (ii) Desert Sun Shareholder approval; (iii) the Final Order shall have been granted in form and substance satisfactory to Yamana and Desert Sun, each acting reasonably; (iv) the Articles of Arrangement shall be in form and substance satisfactory to Yamana and Desert Sun; (v) no law or regulation shall make it illegal or negatively impact the Arrangement so as to have a Material Adverse Effect on Desert Sun or Yamana; (vi) the TSX and AIM shall have conditionally approved the listing thereon, and AMEX shall have authorized for listing, the Yamana Shares to be issued pursuant to the Arrangement; (vii) receipt of all required consents, permits and other regulatory approvals and all third party consents; and (viii) the Yamana Shares to be issued in the United States pursuant to the Arrangement being exempt from registration requirements under the U.S. Securities Act.

The obligations of Yamana to complete the Arrangement are subject to the satisfaction of certain additional conditions in its favour, including, among others, (i) the representations and warranties of Desert Sun under the Arrangement Agreement being true and correct, except where failure or breaches of representations and warranties would not either individually or in the aggregate in the reasonable judgement of Yamana have a Material Adverse Effect on Desert Sun; (ii) there having been no changes, effects, events, occurrences or states of facts that, either individually or in the aggregate, have, or could have, a Material Adverse Effect on Desert Sun; (iii) Desert Sun having complied in all material respects with its covenants in the Arrangement Agreement; (iv) Desert Sun Shareholders holding no more than 5% of the outstanding Desert Sun Shares shall have exercised their right of dissent in respect of the Arrangement Resolution; and (v) each of Stan Bharti and Bruce Humphrey shall have accepted Yamana Shares in consideration of one-half of the "change in control" payment owing to each of them under their respective consulting agreement.

NON-SOLICITATION Pursuant to the Arrangement Agreement, Desert Sun has agreed that it will not, directly or indirectly, through any officer, director, employee, representative, advisor or agent of Desert Sun or the Desert Sun Subsidiary, or otherwise: (a) solicit, initiate or promote (including by way of furnishing information or entering into any form of agreement or understanding) any inquiries or proposals regarding any Acquisition Proposal or potential Acquisition Proposal; (b) participate in any discussions or negotiations regarding any Acquisition Proposal or potential Acquisition Proposal; (c) agree to, approve or recommend or propose publicly to agree to approve or recommend any Acquisition Proposal or potential Acquisition Proposal; (d) accept or enter into any agreement, understanding or arrangement related to any Acquisition Proposal or potential Acquisition Proposal; or make any public announcement or take any other action inconsistent with, or that could reasonably be likely to be regarded as detracting from, the recommendation of the directors of Desert Sun to approve the Combination. Notwithstanding the foregoing, nothing will prevent or restrict the Board of Directors from, prior to the approval of the Arrangement by Desert Sun Shareholders, considering or negotiating any unsolicited bona fide Acquisition Proposal that would be a Superior Proposal or from approving or recommending to Desert Sun Shareholders, or entering into any agreement in respect of, a Superior Proposal in accordance with the terms of the Arrangement Agreement. Desert Sun must notify Yamana within 24 hours of the receipt by any director or officer of Desert 10 Sun of any Acquisition Proposal, any amendment to the foregoing, or any request for non-public information relating to Desert Sun or the Desert Sun Subsidiary. See "The Combination -- Non-Solicitation". SUPERIOR PROPOSAL Neither Desert Sun nor the directors thereof shall accept, approve or recommend or enter into any agreement in respect of an Acquisition Proposal on the basis that it would constitute a Superior Proposal, unless (i) Desert Sun has provided Yamana with a copy of information concerning the Acquisition Proposal, together with any material non-public information provided to the maker of the Acquisition Proposal and not previously provided to Yamana; (ii) such Superior Proposal does not provide for the payment of any break, termination or other fees or expenses to the other party in the event that Desert Sun completes the Combination or any other similar transaction with Yamana or any of its affiliates agreed to prior to termination of the Arrangement Agreement (provided that a Superior Proposal may provide for the payment of expenses to the other party in the event that Desert Sun and Yamana do not enter into an amended agreement in respect of the Superior Proposal, Yamana provides notice that it wishes the Meeting to proceed, a further Superior Proposal is subsequently made by another party and Yamana ultimately succeeds); and (iii) five business days have elapsed from the later of the date on which Yamana received notice of the determination of the Board of Directors to accept, approve, recommend or enter into any agreement in respect of such Superior Proposal and the date Yamana received a copy of the Acquisition Proposal, and Yamana has not within such five business day period agreed to at least match the value per Desert Sun Share of such Superior Proposal. See "The Combination -- Superior Proposal". TERMINATION AND TERMINATION FEES The Arrangement Agreement may be terminated at any time prior to the Effective Date: 1. by mutual written consent of the parties; 2. by either party if: a. a mutual condition or a condition in its favour is not satisfied or waived in accordance with the Arrangement Agreement; or b. the Effective Date is not on or before the Completion Deadline, provided however, if the Arrangement has not been completed by such date because the Meeting has not been held due to the fault of Desert Sun, then Desert Sun shall not be entitled to terminate the Arrangement Agreement; or c. the Meeting is held and completed and the Desert Sun Shareholders do not approve the Arrangement Resolution; or 3. by Yamana or Yamana Subco if there is a Superior Proposal and the directors of Desert Sun withdraw or modify in any manner adverse to Yamana or Yamana Subco their approval or recommendation of the Arrangement, or shall fail, after being requested by Yamana in writing, to reaffirm its approval or recommendation of the Arrangement, or shall have accepted, approved, recommended or entered into any agreement in respect of any Superior Proposal. If Yamana terminates the Arrangement Agreement in connection with: 1. a Superior Proposal and the Board of Directors of Desert Sun has (i) withdrawn or modified in a manner adverse to Yamana their approval or recommendation of the Arrangement; (ii) failed, after being requested by Yamana in writing, to reaffirm its approval or recommendation of the Arrangement as promptly as possible, but in any event within two business days, or (iii) accepted, approved or recommended or entered into an agreement in respect of any Superior Proposal; 11 2. Desert Sun failing to satisfy its covenants regarding non-solicitation and superior proposals in any material respect, as described under the heading "The Arrangement Agreement -- Non-Solicitation and Superior Proposal"; 3. Desert Sun failing to submit the Arrangement for approval to the Desert Sun Shareholders, in accordance with the terms of the Arrangement Agreement, or failing to solicit proxies in connection therewith; then Desert Sun shall pay Yamana an amount in cash equal to $21.5 million. Desert Sun shall also have to pay such a break fee if an Acquisition Proposal has been made to Desert Sun and made known to Desert Sun Shareholders generally and not withdrawn publicly prior to the Meeting, the Desert Sun Shareholders do not approve the Arrangement, and Desert Sun completes an Acquisition Proposal with such third party within nine months following the termination of the Arrangement. Such payment shall be made within five days following the completion of the Acquisition Proposal. Desert Sun shall not be obligated to make more than one such termination payment. Notwithstanding that Desert Sun has entered into an agreement in connection with, or otherwise supports, a Superior Proposal, Yamana may require Desert Sun to hold the Meeting and to place the Arrangement Resolution before the Desert Sun Shareholders for approval. STOCK EXCHANGE LISTINGS Yamana Shares are listed and posted for trading on the TSX under the symbol "YRI", on the AMEX under the symbol "AUY" and on AIM under the symbol "YAU". Desert Sun Shares are listed and posted for trading on the TSX under the symbol "DSM" and on the AMEX under the symbol "DEZ" and are also quoted over the counter on the Berlin and Frankfurt Stock Exchanges under the symbol "DRT". Desert Sun Warrants are listed for trading on the TSX under the symbol "DSM.WT". Following completion of the Arrangement, the Desert Sun Warrants will continue to be listed on the TSX as share purchase warrants of Yamana. See "The Combination -- Stock Exchange Listings". INCOME TAX CONSIDERATIONS Canadian and U.S. Desert Sun Shareholders should consult their own tax advisers for specific advice concerning the tax consequences of the Arrangement. For Canadian federal income tax purposes, a Desert Sun Shareholder whose Desert Sun Shares are capital property will generally realize neither a capital gain nor a capital loss on the exchange of such shares for Yamana Shares under the Arrangement. Desert Sun Shareholders should read carefully the information under "Certain Tax Considerations to Desert Sun Shareholders -- Certain Canadian Federal Income Tax Considerations" that qualifies the information set forth above. For U.S. federal income tax purposes, Yamana and Desert Sun have agreed to treat the Arrangement as a reorganization under the provisions of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended. Even if the Arrangement qualifies as a reorganization, however, a U.S. Holder (as defined under "Certain Tax Considerations to Desert Sun Shareholders -- Certain United States Federal Income Tax Consequences") of Desert Sun Shares may be required to recognize taxable gain (but not loss) on the exchange of its Desert Sun Shares for Yamana Shares if the U.S. Holder has held Desert Sun Shares at any time during which Desert Sun was a "passive foreign investment company" for U.S. federal income tax purposes. Holders of Desert Sun Shares should read carefully the information under "Certain Tax Considerations to Desert Sun Shareholders -- Certain United States Federal Income Tax Consequences". RISK FACTORS Desert Sun Shareholders should consider a number of risk factors in evaluating whether to approve the Arrangement Resolution, which are discussed in this Proxy Circular. These risk factors include certain risks related to the business of 12 Yamana, which are discussed in greater detail herein. See Exhibit A -- "Desert Sun Mining Corp. -- Risk Factors" and Exhibit B -- "Yamana Gold Inc. -- Risk Factors". DISSENTING SHAREHOLDERS Registered Desert Sun Shareholders are entitled to dissent from the Arrangement Resolution in the manner provided in section 190 of the CBCA, as modified by the Interim Order and the Plan of Arrangement. Each Desert Sun Share held by Dissenting Shareholders shall be deemed to be transferred by the holders thereof, without any further act or formality on their part, free and clear of all liens, claims and encumbrances, to Yamana. Yamana will be obliged to pay, as determined on the Arrangement Effective Date, the fair value of such Dissenting Shareholders' Desert Sun Shares. See Exhibit I -- "Dissent Rights". It is suggested that any Desert Sun Shareholders wishing to avail themselves of their rights under those provisions seek their own legal advice as failure to comply strictly with the provisions of the CBCA may prejudice their right of dissent. 13 DESERT SUN SELECTED FINANCIAL DATA The following selected financial data for Desert Sun is based upon, and should be read in conjunction with, the more detailed financial information appearing in the audited comparative consolidated balance sheets of Desert Sun as at December 31, 2005 and 2004 and the audited consolidated statements of shareholders' equity, operations and deficit and cash flows for the twelve-month period ended December 31, 2005, the sixteen-month period ended December 31, 2004 and the twelve-month period ended August 31, 2003, together with the auditors' report thereon and the notes thereto and the management's discussion and analysis in respect thereof incorporated by reference in this Proxy Circular, as well as the unaudited interim financial statements of Desert Sun as at and for the nine months ended September 30, 2005.

In connection with the solicitation of proxies, Desert Sun may retain a soliciting agent to solicit proxies from Desert Sun Shareholders at a cost to Desert Sun. Kingsdale Shareholder Services Inc. has been retained by Desert Sun as an information and proxy solicitation agent in connection with the solicitation of proxies for the Meeting at an agreed cost of $150,000 plus additional costs relating to telephone calls and out-of-pocket expenses. APPOINTMENT OF PROXIES The persons named in the enclosed form of proxy are officers and/or directors of Desert Sun. A Desert Sun Shareholder has the right to appoint a person, who need not be an Desert Sun Shareholder, other than the persons designated in the applicable form of proxy accompanying this Proxy Circular, as nominee to attend and act for and on behalf of such person at the Meeting and may exercise such right by inserting the name of such person in the blank space provided on the form of proxy or by executing a proxy in a form similar to the one enclosed. DEPOSIT OF PROXIES Desert Sun Shareholders who do not expect to attend the Meeting in person are requested to complete, sign, date and return the enclosed form of proxy. An undated but executed proxy will be deemed to be dated the date this Proxy Circular was mailed to Desert Sun Shareholders. Completed proxies returned either by mail or by fax to the office of Desert Sun's transfer agent, Equity Transfer, must be received before noon (Toronto time) on March 29, 2006, or, if the Meeting is adjourned, at least two business days preceding the date of any adjournment of the Meeting. If by mail, shareholders should use the self-addressed envelope enclosed or mail to Equity Transfer, 120 Adelaide Street West, Suite 420, Toronto, Ontario M5H 3C2. If by fax, shareholders should use (416) 361-0470 (Attention: Proxy Department). If you require any assistance in completing your proxy, please call Kingsdale Shareholder Services Inc. toll free at 1-866-588-6864. NON-REGISTERED SHAREHOLDERS Only Registered Desert Sun Shareholders as at the Record Date, or the persons they appoint as their proxies, are entitled to attend, and vote at, the Meeting. However, in many cases, Desert Sun Shares beneficially owned by a holder (a "Non-Registered Shareholder") are registered either: (a) in the name of an Intermediary; or (b) in the name of a clearing agency (such as The Canadian Depository for Securities Limited) of which the Intermediary is a participant. In accordance with the requirements of NI 54-101, Desert Sun has distributed copies of the Meeting Materials to the clearing agencies and Intermediaries for onward distribution to Non-Registered Shareholders. Intermediaries are required to forward the Meeting Materials to Non-Registered Shareholders unless the Non-Registered Shareholders have waived the right to receive them. Intermediaries very often have service companies forward 22 meeting materials to non-registered holders. Non-Registered Shareholders who have not waived the right to receive Meeting Materials will: (a) receive a form of proxy that has already been signed by the Intermediary (usually by facsimile) which indicates the number of Desert Sun Shares beneficially owned by the Non-Registered Shareholder but that has not been completed. This form of proxy need not be signed by the Non-Registered Shareholder. In this case, the Non-Registered Shareholder who wishes to submit a proxy should otherwise properly complete the form of proxy and deposit it with Equity Transfer in the manner described above; (b) more typically, receive a voting instruction form from an Intermediary, which must be completed and signed by the Non-Registered Shareholder in accordance with the directions on the voting instruction form (which may, in some cases, permit the completion of the voting instruction form by telephone); or (c) receive a proxy form as described in the next paragraph. The majority of brokers now delegate responsibility for obtaining instructions from clients to ADP. ADP typically mails a proxy form to the non-registered holders and asks such non-registered holders to return such proxy form to ADP (the ADP form also allows completion of the voting instructions form by telephone or via the internet). ADP then tabulates the results of all instructions received and provides appropriate instructions for the voting of shares to be represented at a shareholders' meeting. A Non-Registered Shareholder receiving a proxy form from ADP cannot use that proxy to vote shares directly at the Meeting. The proxy must be returned to ADP well in advance of the Meeting in order to have the shares voted. The purpose of these procedures is to allow Non-Registered Shareholders to direct the voting of the Desert Sun Shares they beneficially own. Should a Non-Registered Shareholder who receives either a form of proxy or a voting instruction form wish to attend the Meeting and vote in person (or have another person attend and vote on behalf of the Non-Registered Shareholder), the Non-Registered Shareholder should strike out the names of the persons named in the form of proxy and insert the Non-Registered Shareholder's (or such other person's) name in the blank space provided or, in the case of a voting instruction form, follow the directions indicated on that form. In either case, Non-Registered Shareholders should carefully follow the instructions of their Intermediaries and their service companies to ensure that their Desert Sun Shares are voted at the Meeting. EXERCISE OF VOTE BY PROXIES AND DISCRETIONARY AUTHORITY The Desert Sun Shares represented at the Meeting by properly executed proxies given in favour of the persons designated in the printed portion of the accompanying form of proxy will be voted for, against or withheld from voting in accordance with the instructions contained therein, so long as such instructions are certain, on any ballot that may be called for. If no choice is specified in the proxy, such shares will be voted FOR each of the matters proposed by management at the Meeting and described in the Notice of the Meeting. The form of proxy accompanying this Proxy Circular confers discretionary authority upon the nominees named therein with respect to amendments or variations to the matters identified in the Notice of Meeting and with respect to other matters that may properly come before the Meeting. Management of Desert Sun knows of no matters to come before the Meeting, other than those referred to in the Notice of Meeting. However, if any other matters that are not now known to management of Desert Sun should properly come before the Meeting, the shares represented by proxies given in favour of management nominees will be voted on such matters in accordance with the best judgment of the nominee. REVOCATION OF PROXIES A Registered Desert Sun Shareholder may revoke a proxy by: (a) completing and signing a proxy bearing a later date and depositing it with Equity Transfer within the same time periods in advance of the Meeting as set forth above under "Deposit of Proxies"; (b) depositing an instrument in writing executed by the holder or by his or her attorney authorized in writing or, if the holder is a corporation, under its corporate seal by an officer or attorney thereof duly authorized, indicating 23 the capacity under which such officer or attorney is signing, either at the registered office of Desert Sun at any time up to and including noon, Toronto time, on the last business day preceding the day of the Meeting, or any adjournment thereof, at which the proxy is to be used, or with the Chairman of the applicable Meeting on the day of such Meeting, or any adjournment thereof; or (c) in any other manner permitted by law. A Non-Registered Shareholder may revoke a voting instruction form and a vote given to an Intermediary at any time by written notice, except that an Intermediary is not required to act on a revocation of a voting instruction form or to vote if such revocation is not received at least seven days prior to the Meeting. INFORMATION CONCERNING THE MEETING DATE, TIME AND PLACE OF MEETING The Meeting is to be held at The Fairmont Royal York, Tudor Room 7-8, 100 Front Street West, Toronto, Ontario, M5J 1E3 on Friday, March 31, 2006 at 10:30 a.m. (Toronto time) as set forth in the Notice of Meeting. RECORD DATE AND SHARES ENTITLED TO VOTE At the close of business on the Record Date, there were 105,164,482 Desert Sun Shares outstanding, each carrying the right to one vote on matters at the Meeting. Only Desert Sun Shareholders of record on the Record Date are entitled to receive notice of, and vote at, the Meeting. MATTERS TO BE CONSIDERED The Meeting will be constituted as an annual and special meeting of Desert Sun Shareholders. The Desert Sun Shareholders will be asked to consider and vote upon: (i) the election of directors of Desert Sun for the ensuing year; (ii) the appointment of auditors of Desert Sun for the ensuing year and the authorization of the directors to fix their remuneration; (iii) pursuant to the Interim Order, the Arrangement Resolution; and (iv) such other matters as may properly come before the Meeting. PRINCIPAL SHAREHOLDERS As at the Record Date, to the knowledge of the directors and officers of Desert Sun, no person or company beneficially owned, directly or indirectly, or exercised control or direction over, more than 10% of the votes attached to all of the Desert Sun Shares then outstanding. QUORUM AND VOTES REQUIRED FOR CERTAIN MATTERS The presence of two persons, each entitled to vote at the Meeting as a shareholder or a duly appointed proxyholder, holding or representing an aggregate of not less than 5% of the Desert Sun Shares entitled to vote at the Meeting will constitute a quorum for the Meeting. Desert Sun is subject to the securities laws of each of the provinces of Canada. The rules impose various requirements on issuers that propose to effect certain types of transactions involving related parties vis-a-vis the issuer. These requirements include enhanced disclosure, the requirement to prepare and summarize the results of a formal valuation of the transaction and the requirement to have the transaction approved by a simple majority of disinterested shareholders. Mr. Stan Bharti is entitled, pursuant to his Desert Sun Consulting Agreement, to receive a change in control payment, provided that his agreement is terminated by him or by Yamana within one year from such change in control, equal to three times his current annual base fee, plus any bonus paid to him by Desert Sun during the prior 36 months and, if cessation of benefits occurs, an amount equal to the value of any benefits entitled thereto for that period in an amount equal to the value of such benefits as determined by Desert Sun's auditors. See "Information Concerning the Meeting -- Interest of 24 Certain Persons in the Arrangement". The Combination will constitute a change in control of Desert Sun under the terms of his Desert Sun Consulting Agreement. In connection with the Combination, Mr. Bharti will receive one half of the change in control payment in Yamana Shares at a price of $9.12 per Yamana Share, representing the five-day weighted average trading price per such Yamana Share on the TSX up to and including the day immediately prior to the date of the Arrangement Agreement. As a result, the Arrangement constitutes (i) a business combination for the purposes of OSC Rule 61-501; and (ii) a "going private transaction" for the purposes of Regulation Q-27 of the Autorite des marches financiers du Quebec. Desert Sun has determined that a formal valuation of the Combination is not required under either OSC Rule 61-501 or Regulation Q-27 in respect of the Combination. Pursuant to the Interim Order, the Arrangement Resolution requires the affirmative vote of not less than two-thirds of the votes cast by Desert Sun Shareholders, and the affirmative vote of not less than one-half of the votes cast by disinterested Desert Sun Shareholders, who vote in respect thereof, in person or by proxy, at the Meeting. OSC Rule 61-501 and Regulation Q-27 also require that the Arrangement Resolution be approved by a majority of the votes cast by disinterested Desert Sun Shareholders at the Meeting. Mr. Bharti, who owns or controls Desert Sun Shares representing approximately 1.1% of the Desert Sun Shares, will not be entitled to vote such shares as part of the disinterested vote. INTERESTS OF CERTAIN PERSONS IN THE ARRANGEMENT In considering the recommendation of the Board of Directors to vote in favour of the Arrangement Resolution, Desert Sun Shareholders should be aware that certain directors and/or officers of Desert Sun have interests in the Arrangement that are different than the interests of Desert Sun Shareholders generally. The Desert Sun Consulting Agreements provide for change in control payments equal to three times the current annual base fees, plus any bonus paid by Desert Sun to each of the officers during the prior 36 months and, if a cessation of benefits occurs, a payment equal to the value of the benefits entitled thereto for that period in an amount equal to the value of such benefits as determined by Desert Sun's auditors, if there is a change in control of Desert Sun and the resulting company or the officer elects to terminate his or her respective agreement within one year of the date of such change of control. The Combination will constitute a change in control of Desert Sun under the terms of the Desert Sun Consulting Agreements. In connection with the Combination, and upon the Desert Sun Consulting Agreement of Mr. Bharti and Mr. Humphrey being terminated, they are entitled to receive their respective change in control payment, and they have agreed to receive one-half of the change in control payment in Yamana Shares, at a price of $9.12 per Yamana Share issued, representing the five-day weighted average trading price per such Yamana Share on the TSX up to and including the day immediately prior to date of the Arrangement Agreement. Desert Sun expects that the Desert Sun Consulting Agreement with each of Mr. Bharti and Mr. Humphrey will be terminated following the Arrangement becoming effective. Pursuant to the share compensation plan of Desert Sun, all Desert Sun Shares previously granted but not yet issued under the plan will vest and be issued immediately prior to the Effective Time. Directors and executive officers of Desert Sun collectively hold, as at the date hereof, an aggregate of approximately 2,096,192 Desert Sun Shares and 7,122,997 Desert Sun Options that, following completion of the Combination, will entitle the holders thereof to acquire approximately 1,257,715 Yamana Shares and 4,273,799 Yamana Shares, respectively. The directors and executive officers of Desert Sun do not own any Yamana Shares. DISSENT RIGHTS Desert Sun Shareholders who oppose the special resolution are entitled to dissent in accordance with the Dissent Procedures set out in Exhibit I -- "Dissent Rights". Exhibit I -- "Dissent Right" is only a summary of the dissenting shareholder provisions of the CBCA (as modified by the Interim Order and the Plan of Arrangement), which are technical and complex. It is suggested that any Desert Sun Shareholder wishing to avail themselves of their rights under those provisions seek their own legal advice as failure to comply strictly with the provisions of the CBCA may prejudice their right of dissent. 25 THE COMBINATION THE ARRANGEMENT Desert Sun entered into the Arrangement Agreement that will, subject to the terms and conditions of the Arrangement Agreement, result in the business combination of Desert Sun and Yamana by way of the Arrangement, a Court-approved plan of arrangement under the CBCA. As a result of the Combination, among other things, Desert Sun will become a wholly-owned subsidiary of Yamana and each Desert Sun Shareholder (other than Dissenting Shareholders, Yamana and its affiliates) will be entitled to receive Yamana Shares in exchange for the Desert Sun Shares held by such Desert Sun Shareholder on the basis of 0.6 of a Yamana Share for each Desert Sun Share held by such Desert Sun Shareholder, all pursuant to the provisions of the Plan of Arrangement. Upon the completion of the Arrangement, each holder of a Desert Sun Warrant or Desert Sun Option will be entitled to receive upon the subsequent exercise thereof, in accordance with its terms, and shall accept in lieu of the number of Desert Sun Shares otherwise issuable upon exercise, the number of Yamana Shares that such holder would have been entitled to receive as a result of the Arrangement if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was previously entitled upon such exercise. The conditions to the Combination include, among others, approval by at least two-thirds of the votes cast by Desert Sun Shareholders at the Meeting, approval by one-half of the votes cast by disinterested Desert Sun Shareholders at the Meeting, the approval of the Court, and the conditional approval of the TSX, AMEX and AIM. Subject to the conditions in the Arrangement Agreement being satisfied or waived, Desert Sun and Yamana Subco will apply to the Court for the Final Order approving the Plan of Arrangement under the provisions of section 192 of the CBCA. Upon obtaining the Final Order, Desert Sun will file the Articles of Arrangement with the Director. The Arrangement will become effective upon obtaining a certificate of arrangement from the Director. See "The Arrangement Agreement -- Conditions to Closing". BACKGROUND The following is a summary of the meetings, negotiations and discussions between Desert Sun and Yamana that preceded the execution of the Arrangement Agreement. In the fall of 2004, Mr. Bruce Humphrey, the President and Chief Executive Officer of Desert Sun, had an informal meeting with Mr. Peter Marrone, the President and Chief Executive Officer of Yamana, and Mr. Greg McKnight, Executive Vice President, Business Development of Yamana. During the meeting, the concept of a business combination between the two companies was discussed in a preliminary fashion, but was not further pursued at that time. On January 24, 2006, Mr. Stan Bharti, the Chairman of Desert Sun, met with Mr. Marrone and Mr. McKnight to discuss a possible transaction between Desert Sun and Yamana. As a result of this meeting, Mr. Bharti discussed the merits of a possible Yamana transaction with Mr. Humphrey and other members of the Desert Sun management and Board of Directors. In response to a number of companies making informal approaches to the management of Desert Sun regarding possible transactions involving Desert Sun, on January 27, 2006, Desert Sun retained Sprott Securities to act as its financial advisor in connection with a possible transaction. At the meeting of the Board of Directors held on January 27, 2006, and at other meetings of the Board of Directors at which matters relating to the Combination were discussed, Messrs Bharti and Humphrey declared their interest in the possible transaction relating to their status as directors and officers of Desert Sun who may be retained by Yamana following the Combination. 26 Subsequent to retaining Sprott Securities as its financial advisor, Desert Sun management and Sprott Securities had a number of discussions with other companies with a view to exploring possible alternative transactions that would maximize shareholder value. On January 29, 2006, Desert Sun and Yamana entered into a confidentiality agreement to enable them to conduct due diligence reviews of each other. As part of its initial due diligence review, during the week of January 30, 2006, Yamana conducted preliminary site visits to the Jacobina mine and performed a review of certain technical and other information relating to Desert Sun. During the week of February 6, 2006, Desert Sun personnel conducted site visits to the principal properties of Yamana and performed a review of certain technical and other information relating to Yamana. During the week, Yamana personnel conducted additional and more extensive site visits to the Jacobina mine. On February 12, 2006, the Board of Directors formed the Special Committee to review a possible transaction with Yamana. The Special Committee was empowered to retain legal counsel and a financial advisor. On February 13, 2006, the Special Committee retained GMP as its financial advisor and it retained Wildeboer Dellelce LLP as its legal advisors. From February 14, 2006 to February 22, 2006, Desert Sun, Yamana and their respective legal advisors negotiated the terms and exchanged drafts of the Arrangement Agreement and the Plan of Arrangement and continued with legal, financial and technical due diligence. On February 20, 2006, GMP delivered the GMP Fairness Opinion to the Special Committee. On February 20, 2006, the Special Committee determined that the Arrangement and the terms of the Arrangement Agreement were in the best interests of Desert Sun Shareholders and that it would recommend to the Board of Directors that the Board of Directors approve the Arrangement and the terms of the Arrangement Agreement and recommend that Desert Sun Shareholders vote to approve the Arrangement Resolution. On February 20, 2006, Sprott Securities delivered the Sprott Securities Fairness Opinion to the Board of Directors. On February 20, 2006, the Board of Directors received presentations from senior management and outside counsel as to the results of the due diligence examination of Yamana. The Board of Directors also discussed recommendations of the Special Committee and the terms of the Arrangement Agreement and approved, among other things, the Arrangement and the terms of the Arrangement Agreement, subject to the satisfactory completion of negotiations of such agreement. On February 22, 2006, Desert Sun and Yamana executed and delivered the Arrangement Agreement and a public announcement was made by a joint press release of Desert Sun and Yamana. On March 1, 2006, the Board of Directors approved, among other things, the contents and mailing of this Proxy Circular. BENEFITS OF THE COMBINATION The Board of Directors believes that the Combination will have the following benefits for Desert Sun Shareholders: 1. the Combination offers an attractive premium of approximately 24% to the weighted average trading price of Desert Sun and Yamana for the ten-day period ending on February 21, 2006, the date prior to the date on which the transaction was announced; 2. the combined company will be a significant gold producer with one of the largest production growth profiles; 3. the combined company will be well positioned for internal growth and have the financial strength and flexibility to take advantage of consolidation and acquisition opportunities in the gold mining industry; 4. the combined company will have interests in six producing gold operations, with estimated annualized gold production of approximately 450,000 gold equivalent ounces in 2006, making it one of the largest gold producers in Brazil; 27 5. as a result of the Combination, Desert Sun will mitigate the operational risks inherent in a one-mine company; 6. the combined company will have immediate and near-term production growth opportunities through the development of the Chapada mine and the Morro do Vento project; 7. the combined company expects to reduce expenses, including costs of production, based on the proximity of the Jacobina mine to Fazenda Brasileiro and its ability to take advantage of general and administrative merger synergies; 8. the combined company will have a market capitalization of approximately $2.4 billion (based on the closing price of the Desert Sun Shares and the Yamana Shares on the TSX on February 22, 2006), which will facilitate the addition of the securities of the combined company to gold indices and will enhance its ability to compete for world class projects; and 9. the combined company will have an experienced management team with significant operating experience. SPECIAL COMMITTEE AND FINANCIAL ADVISOR A Special Committee of the Board of Directors was formed to review the Combination and reported to the Board of Directors respecting its recommendations and conclusions. The Special Committee concluded that the Arrangement is fair to Desert Sun Shareholders and that the Combination is in the best interests of Desert Sun and Desert Sun Shareholders. Further, the Special Committee recommended that the Board of Directors proceed with the Arrangement. In reaching its conclusions and formulating its recommendations, the Special Committee considered the expected benefits from the Combination as well as a number of factors including: (a) information regarding Yamana, its assets and properties (see a summary of such information set forth in "Exhibit B -- Yamana Gold Inc."); (b) information regarding Yamana with respect to its historical and current financial condition, business and operations; (c) historical information regarding the market prices and trading information of the Desert Sun Shares and the Yamana Shares; (d) information regarding Yamana obtained by Desert Sun management from its due diligence review of Yamana and, in particular, technical information obtained during visits to Yamana properties; (e) Desert Sun management concluded that the significant opportunities for cost savings in Brazil that are expected to result from the Combination will not be available to third parties, hence, in their opinion, making it difficult for a third party to offer consideration in excess of what is offered under the Combination; (f) the anticipated size and market liquidity of the combined company, subsequent to the Arrangement; (g) that the Yamana Shares offered in connection with the Arrangement provide Desert Sun Shareholders with the opportunity to be shareholders of a larger, more diversified company; (h) Desert Sun Shareholders will retain their ability to benefit from the growth prospects represented by the combined company by receiving 0.6 of a Yamana Share for each Desert Sun Share held; 28 (i) the Exchange Ratio implied a price of $5.57 per Desert Sun Share representing a premium of approximately 24% based on the volume-weighted- average trading prices of Yamana and Desert Sun for the ten-day period ending on February 21, 2006, the date prior to the date on which the Arrangement was announced; (j) the GMP Fairness Opinion and the Sprott Securities Fairness Opinion, which both concluded that the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders; (k) the Special Committee has relied on the fact that Sprott Securities had previously been retained as financial advisor to identify and approach potential third parties that demonstrated a real interest in pursuing a transaction at a price/consideration comparable to that offered pursuant to the Combination and that would be motivated and able to complete a transaction in a reasonable period of time; (l) for Canadian federal income tax purposes, Desert Sun Shareholders who hold their Desert Sun Shares as capital property generally will be able to exchange their Desert Sun Shares for Yamana Shares under the Arrangement on a tax-deferred basis under the Tax Act (see "Certain Tax Considerations to Desert Sun Shareholders -- Certain Canadian Federal Income Tax Considerations"); (m) the view of the Desert Sun Board of Directors that the terms and conditions of the Arrangement Agreement, including the amount of the Termination Fee and the circumstances under which it is payable, do not prevent, or unreasonably deter, an unsolicited third party from proposing or making a Superior Proposal, provided that Desert Sun complies with the terms of the Arrangement Agreement; (n) the Arrangement Resolution must be approved by not less than two-thirds of the votes cast at the Meeting by Desert Sun Shareholders and a majority of the votes cast at the Meeting by disinterested Desert Sun Shareholders; (o) the Arrangement requires approval of the Court, which will consider, among other things, the fairness of the Arrangement to Desert Sun Shareholders; (p) the risks associated with the completion of the Combination, and the risks associated with not completing the Combination; and (q) under the Arrangement, Registered Desert Sun Shareholders will have dissent rights. The Special Committee also considered current industry, economic and market conditions and trends as well as the reasons set forth under "The Combination -- Benefits for the Combination". 29 FAIRNESS OPINION OF GMP The Special Committee of Desert Sun formally engaged GMP as its financial advisor pursuant to the GMP Engagement Letter. As part of its engagement, GMP was asked by the Special Committee, among other things, to consider the proposed Combination and provide its opinion as to its fairness, from a financial point of view, to Desert Sun Shareholders. On February 20, 2006, GMP provided in writing to the Special Committee its opinion that as of that date, based upon and subject to the considerations described therein, the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders. The full text of the GMP Fairness Opinion, which sets forth, among other things, information reviewed, matters considered and limitations on the scope of the review undertaken by GMP in rendering the GMP Fairness Opinion, is attached as Exhibit D to this Proxy Circular. The GMP Fairness Opinion was prepared solely for the benefit and use of the members of the Special Committee in its consideration of the Arrangement and addresses only the fairness of the Arrangement, from a financial point of view, to the Desert Sun Shareholders. The GMP Fairness Opinion states that it is not to be construed as a recommendation to any Desert Sun Shareholder as to whether to vote in favour of the Arrangement. The summary of the GMP Fairness Opinion set forth in this Proxy Circular is qualified in its entirety by reference to the full text of the GMP Fairness Opinion. Desert Sun Shareholders are urged to read the GMP Fairness Opinion carefully and in its entirety. The GMP Fairness Opinion was rendered on the basis of conditions prevailing as at the date of the GMP Fairness Opinion and the condition and prospects, financial and otherwise, of Desert Sun, as reflected in the information and documents reviewed by GMP and as they were represented to GMP in discussions with management of Desert Sun. Subsequent developments may affect the GMP Fairness Opinion, and GMP does not have any obligation to update, revise, or reaffirm the GMP Fairness Opinion. GMP is an investment dealer that provides research, corporate finance advice and services, and engages in trading and investment banking. GMP has participated in a significant number of transactions involving mining companies, including transactions involving both Desert Sun and Yamana, and its investment banking professionals have extensive experience in preparing valuations and fairness opinions. GMP prepared the GMP Fairness Opinion in an impartial and objective fashion. GMP acts as a trader and dealer, both as principal and agent, in all major financial markets and, accordingly GMP and its clients may have, and may in the future have, long or short positions in the securities of Desert Sun, Yamana or any of their respective associates or affiliates and, from time to time, may have executed or may execute transactions on behalf of Desert Sun or Yamana or on behalf of their clients for which it receives compensation. As an investment dealer, GMP conducts research on securities and may, in the ordinary course of its business, provide research reports and investment advice to its clients on investment matters, including matters involving an investment in Desert Sun or Yamana. GMP is not an insider, associate or affiliate (as those term are defined) of Desert Sun or Yamana or any of their respective associates or affiliates. GMP has previously acted as an indemnitor to Desert Sun in respect of four financings pursuant to which Desert Sun has raised an aggregate of $91.2 million. See the GMP Fairness Opinion (attached hereto as Exhibit D) under the heading "Relationship with Interested Parties". Pursuant to the Engagement Letter, the Special Committee has agreed to pay GMP certain fees. Such fees are not contingent, in whole or in part, upon the successful completion of the Combination, nor are they dependent on the conclusions reached by GMP. Desert Sun has also agreed to indemnify GMP and certain related persons against certain losses, claims, damages and liabilities that may be incurred in connection with the Arrangement or their engagements. FAIRNESS OPINION OF SPROTT SECURITIES Desert Sun formally engaged Sprott Securities as its financial advisor pursuant to the Engagement Letter. As part of its engagement, Sprott Securities was asked by Desert Sun, among other things, to consider the proposed Combination and 30 provide its opinion as to its fairness, from a financial point of view, to Desert Sun Shareholders. On February 20, 2006, Sprott Securities provided in writing to the Board of Directors its opinion that as of that date, based upon and subject to the considerations described therein, the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders. The full text of the Sprott Securities Fairness Opinion, which sets forth, among other things, assumptions made, information reviewed, matters considered and limitations on the scope of the review undertaken by Sprott Securities in rendering the Sprott Securities Fairness Opinion, is attached as Exhibit C to this Proxy Circular. The Sprott Securities Fairness Opinion was prepared solely for the benefit and use of the members of the Board of Directors in its consideration of the Arrangement and addresses only the fairness of the Arrangement, from a financial point of view, to the Desert Sun Shareholders. The Sprott Securities Fairness Opinion states that it does not constitute a recommendation to any Desert Sun Shareholder as to whether such Desert Sun Shareholder should vote in favour of the Arrangement or how such Desert Sun Shareholder should vote with respect to the Arrangement should the Arrangement or any other matter come to a vote of Desert Sun Shareholders. The summary of the Sprott Securities Fairness Opinion set forth in this Proxy Circular is qualified in its entirety by reference to the full text of the Sprott Securities Fairness Opinion. Desert Sun Shareholders are urged to read the Sprott Securities Fairness Opinion carefully and in its entirety. The Sprott Securities Fairness Opinion was rendered on the basis of conditions prevailing as at the date of the Sprott Securities Fairness Opinion and the condition and prospects, financial and otherwise, of Desert Sun, as reflected in the information and documents reviewed by Sprott Securities and as they were represented to Sprott Securities in discussions with management of Desert Sun. Subsequent developments may affect the Sprott Securities Fairness Opinion, and Sprott Securities does not have any obligation to update, revise, or reaffirm the Sprott Securities Fairness Opinion. Sprott Securities is a licensed and registered investment dealer that provides investment research and corporate finance advice and services, and engages in trading and investment banking. Sprott Securities has participated in a significant number of transactions involving mining companies, including transactions involving both Desert Sun and Yamana, and its investment banking professionals have experience with advising with respect to mergers, acquisitions, divestitures, valuations, fairness opinions and other capital market matters. In the last 24 months, Sprott Securities and its affiliates provided to the parties to the Arrangement Agreement those services set out in the Sprott Securities Fairness Opinion (which is attached hereto as Exhibit C) under the heading "Sprott's Engagement, Background and Assignment". Pursuant to the Sprott Securities Engagement Letter, Desert Sun has agreed to pay Sprott Securities an advisory fee equal to 0.5% of the value attributed to Desert Sun in the Arrangement, which is payable upon completion thereof, and reimburse Sprott Securities for all expenses reasonably incurred by Sprott Securities in connection with its rendering of financial advisory services, and Desert Sun has also agreed to indemnify Sprott Securities and certain related persons against certain losses, claims, damages and liabilities that may be incurred in connection with the Arrangement or their engagements. RECOMMENDATION OF THE BOARD OF DIRECTORS After considering the report of the Special Committee and the Sprott Securities Fairness Opinion, the Board of Directors adopted the Special Committee's recommendation, concluded that the Arrangement is in the best interests of Desert Sun and fair to Desert Sun Shareholders and authorized the entry by Desert Sun into the Arrangement Agreement and all related agreements. The Board of Directors has unanimously approved the Arrangement Agreement and the Plan of Arrangement and unanimously recommends that the Desert Sun Shareholders vote IN FAVOUR of the Arrangement Resolution at the Meeting. In reaching its conclusions and formulating its recommendations, the Board of Directors considered a number of factors, including the recommendation of the Special Committee, the Sprott Securities Fairness Opinion, the expected benefits of the Combination, the risks associated with completing the Combination as well as the factors listed above considered by the Special Committee. The discussion of the information and factors considered and given weight by the Board of Directors is not intended to be exhaustive, but is believed to include all material factors considered by the Board of Directors. In reaching the 31 determination to approve and recommend the Arrangement Resolution, the Board of Directors did not assign any relative or specific weight to the factors that were considered, and individual directors may have given a different weight to each factor. SUPPORT AGREEMENTS Each of the officers and directors of Desert Sun have agreed: 1. to vote or cause to be voted the Desert Sun Shares beneficially owned by him or her or over which he or she exercises control or direction in favour of the Arrangement Resolution; 2. except as permitted by the Arrangement Agreement, not to initiate, solicit, promote or encourage inquiries or the submission of proposals in respect of any Acquisition Proposal or take any other action that would or could reasonably reduce the likelihood of success of completion of the Combination; and 3. not to sell, transfer, option or otherwise dispose of any Desert Sun Shares beneficially owned by him or her or over which he or she exercises control or direction. The obligations of such officers and directors will terminate to the extent there is a Superior Proposal and otherwise if the Arrangement Agreement is terminated in accordance with its terms. Such officers and directors of Desert Sun collectively beneficially own and exercise control or direction over an aggregate of 2,096,192 Desert Sun Shares, representing approximately 1.99% of the Desert Sun Shares outstanding. COURT APPROVAL AND COMPLETION OF THE ARRANGEMENT The Arrangement must be approved by the Court. Prior to the mailing of this Proxy Circular, Desert Sun obtained the Interim Order providing for the calling and holding of the Meeting and other procedural matters. A copy of the Interim Order and Notice of Application for the Final Order is attached to this Proxy Circular as Exhibits G and H, respectively. Subject to the approval of the Arrangement Resolution by the Desert Sun Shareholders at the Meeting, the hearing in respect of the Final Order is scheduled to take place on April 4, 2006 at 10:00 a.m. (Toronto time) or shortly thereafter in the Court at 393 University Avenue, 8th Floor, Toronto, Ontario. All Desert Sun Shareholders who wish to participate or be represented or to present evidence or arguments at that hearing must serve and file a notice of appearance as set out in the Interim Order and satisfy all other applicable requirements. At the hearing in respect of the Final Order, the Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement as proposed or as amended in any manner as the Court may direct, subject to compliance with such terms and conditions, if any, as the Court may deem appropriate. Assuming that the Final Order is granted and the other conditions in respect of the Arrangement as set out in the Arrangement Agreement are satisfied or waived, it is anticipated that the Articles of Arrangement will be filed with the Director to give effect to the Plan of Arrangement and the various other documents necessary to complete the Arrangement as contemplated under the Arrangement Agreement will be executed and delivered. It is currently anticipated that the Effective Date will be on or about April 5, 2006. DESCRIPTION OF THE PLAN OF ARRANGEMENT Subject to the conditions in the Arrangement Agreement being satisfied or waived, Desert Sun will apply to the Court for the Final Order approving the Plan of Arrangement under section 192 of the CBCA. In connection with the Arrangement, Desert Sun and Yamana Subco will amalgamate under the CBCA and each Desert Sun Shareholder (other than Dissenting Shareholders, Yamana and its affiliates) will be entitled to receive Yamana Shares in exchange for the Desert Sun Shares held by such Desert Sun Shareholder on the basis of 0.6 of a Yamana Share for each Desert Sun Share held by such Desert Sun Shareholder, all pursuant to the provisions of the Plan of Arrangement. 32 On the Effective Date and pursuant to the provisions of the Plan of Arrangement, the following will occur without further act or formality: (a) Desert Sun and Yamana Subco will amalgamate and continue as one corporation on the terms prescribed in the Plan of Arrangement; (b) all Desert Sun Shares held by Yamana Subco will be cancelled without any repayment of capital in respect thereof; (c) all Desert Sun Shares held by Desert Sun Shareholders (other than Dissenting Shareholders) will be exchanged for Yamana Shares on the basis of 0.6 of a Yamana Share for each Desert Sun Share, and each Desert Sun Share so exchanged will be cancelled without any repayment of capital in respect thereof; (d) each Desert Sun Warrant will entitle the holder to receive upon the exercise thereof, in lieu of the number of Desert Sun Shares otherwise issuable upon the exercise thereof, the number of Yamana Shares that the holder would have been entitled to receive as a result of the transactions contemplated by the Plan of Arrangement if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was theretofore entitled upon such exercise, at a price per Yamana Share issued of $4.167; (e) each Desert Sun Option will entitle the holder to receive upon the exercise thereof, in lieu of the number of Desert Sun Shares otherwise issuable upon the exercise thereof, the number of Yamana Shares that the holder would have been entitled to receive as a result of the transactions contemplated by the Plan of Arrangement if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was theretofore entitled upon such exercise, at a price per Yamana Share issued adjusted to reflect the Combination. Desert Sun Options shall continue to be governed by and be subject to the terms of the Desert Sun Stock Option Plan and applicable agreement thereunder except to the extent that such Desert Sun Option will expire on the earlier of the expiry date for such option and six months after the Effective Date (instead of in 90 days as provided in the Stock Option Plan) if the holder thereof ceases to be an employee, consultant or director of Desert Sun as of the Effective Date and does not become an employee, consultant or director of Yamana or a material subsidiary thereof on that date; (f) each common share of Yamana Subco will be exchanged for one common share of Amalco; (g) Desert Sun Shareholders (other than Dissenting Shareholders) will become shareholders of Yamana; and (h) Amalco will be a wholly-owned subsidiary of Yamana. As a result of the Arrangement, based on the number of Yamana Shares outstanding on February 28, 2006, existing Desert Sun Shareholders will hold approximately 24% of the approximately 262.3 million Yamana Shares to be outstanding upon completion of the Arrangement, assuming no exercise of options or warrants of Desert Sun and Yamana outstanding subsequent to February 28, 2006. After giving effect to the Arrangement, approximately 30.5 million Yamana Shares will remain reserved for issuance upon exercise of Yamana and Desert Sun options and warrants (assuming that on the Effective Date the options and warrants of Yamana and Desert Sun outstanding on February 28, 2006, as further described below, have not been exercised or otherwise expired and no new convertible securities of Yamana or Desert Sun have been issued or granted). Pursuant to the share compensation plan of Desert Sun, all Desert Sun Shares previously granted but not yet issued under the plan will vest and be issued immediately prior to the Effective Date, and participants under the share compensation plan will not have any continuing rights to receive Yamana Shares under the share compensation plan. As of February 28, 2006, Yamana had convertible securities and options outstanding entitling the holders thereof, upon exercise, to acquire a total of approximately 12.9 million Yamana Shares. If all outstanding convertible securities and options of Yamana were exercised and converted into Yamana Shares prior to the Effective Date, a total of 275,238,818 Yamana Shares would be outstanding and, following the Arrangement, Desert Sun Shareholders would hold approximately 23% of the total outstanding Yamana Shares. In addition, Desert Sun Warrants and Desert Sun Options outstanding as of February 28, 2006 entitle the holders thereof, upon exercise, to acquire a total of 28,508,370 Desert Sun Shares, which upon completion of the Arrangement will entitle the holders thereof, upon 33 exercise, to acquire a total of approximately 17,105,022 Yamana Shares. If all outstanding Desert Sun Warrants and Desert Sun Options were exercised following the Arrangement, there would be a total of approximately 292,808,847 Yamana Shares outstanding on a fully diluted basis and Desert Sun Shareholders would hold approximately 27.5% of the total outstanding Yamana Shares. The following table sets forth information regarding the approximate number of Yamana Shares to be held by Desert Sun Shareholders and Yamana shareholders upon completion of the Arrangement (assuming that no Yamana or Desert Sun outstanding warrants or options are exercised following February 28, 2006). Number of Approximate % of Issued and Yamana Shares Outstanding Yamana Shares Current Desert Sun Shareholders...................... 63.1 million 24% Current Yamana Shareholders.......................... 199.2 million 76% Total................................................ 262.3 million 100% PROCEDURE FOR THE EXCHANGE OF DESERT SUN SHARE CERTIFICATES A Letter of Transmittal (printed on blue paper) is included in the materials accompanying this Proxy Circular for use in exchanging certificates representing Desert Sun Shares. The Letter of Transmittal should be completed and delivered to CIBC Mellon in accordance with the instructions contained in the Letter of Transmittal. The Letter of Transmittal form is also available via SEDAR at www.sedar.com. Upon the return of a properly completed Letter of Transmittal, together with certificates representing Desert Sun Shares (and such other documentation as required by CIBC Mellon), certificates for the appropriate number of Yamana Shares will be issued without charge. No fractional Yamana Shares will be issued. Desert Sun Shareholders should, as soon as possible, deliver to CIBC Mellon at any of the offices of CIBC Mellon listed in the Letter of Transmittal the following: (a) the certificate or certificates representing the Desert Sun Shares that the Desert Sun Shareholder wishes to have exchanged for Yamana Shares; (b) a Letter of Transmittal in the accompanying form as required by the rules and instructions set out in the Letter of Transmittal; and (c) any other documents specified in the instructions set out in the Letter of Transmittal. Yamana Shares will be issued for Desert Sun Shares and delivered by CIBC Mellon to appropriate Desert Sun Shareholders as soon as practicable following the Effective Date, but only if CIBC Mellon has actually received the above documents. The Effective Date is expected to occur on or about April 5, 2006, provided that all other regulatory approvals have been obtained. If on such date any required regulatory approval has not yet been obtained, the Effective Date will be the date immediately following the date the last of such approvals is obtained. Except as otherwise provided in the instructions to the Letter of Transmittal, an Eligible Institution must guarantee the signature on the Letter of Transmittal. If a Letter of Transmittal is signed by a person other than the registered owner(s) of the certificate(s) to which the Letter of Transmittal relates, and in certain other circumstances as set forth in the Letter of Transmittal, the deposited certificate(s) must be endorsed or be accompanied by an appropriate share transfer power of attorney duly and properly completed by the registered owner(s), with the signature on the endorsement panel or share transfer power of attorney guaranteed by an Eligible Institution. FRACTIONAL SHARES No fractional Yamana Shares will be issued to Desert Sun Shareholders upon the surrender of Desert Sun Shares for exchange. Any fractional number of Yamana Shares will be rounded up (if the fractional interest is 0.5 or more) or down (if the fractional interest is less than 0.5). 34 STOCK EXCHANGE LISTINGS The Desert Sun Shares are listed and posted for trading on the TSX under the symbol "DSM", on AMEX under the symbol "DEZ" and are posted for trading on the Frankfurt and Berlin Stock Exchanges under the symbol "DRT". Yamana Shares are listed and posted for trading on the TSX under the symbol "YRI", on AMEX under the symbol "AUY", and on AIM under the symbol "YAU". It is a condition to the Arrangement that the Yamana Shares issued pursuant to the Arrangement be approved for listing on the TSX, AMEX and AIM. The Desert Sun Warrants are to be listed on the TSX as share purchase warrants of Yamana. Following the Arrangement, the Desert Sun Shares will be de-listed from the TSX and AMEX. REGULATORY MATTERS BRAZILIAN ANTI-TRUST LAW Under Brazilian Law No. 8,884, enacted on June 11, 1994, certain merger and acquisition transactions are subject to the review of the Brazilian Antitrust System, which is comprised of (i) the Secretariat of Economic Monitoring, which is the body that is responsible to the Ministry of Finance, (ii) the secretariat of Economic Law, which is the body that is responsible to the Ministry of Justice, and (iii) the Administrative Council for Economic Defence, which is the body that is to render the final approval. Yamana and Desert Sun are evaluating whether a filing is required to be submitted to the Brazilian antitrust authorities in respect of the Combination. QUALIFICATION AND RESALE OF YAMANA SHARES CANADA The distribution of Yamana Shares issuable pursuant to the Arrangement will be exempt from the prospectus and registration requirements of securities legislation in each province and territory of Canada. Further, the distribution of Yamana Shares issuable upon exercise of Desert Sun Warrants or Desert Sun Options will be exempt from the prospectus and registration requirements of securities legislation in each province and territory of Canada. Subject to certain disclosure and regulatory requirements and to customary restrictions applicable to distributions of shares pursuant to "control distributions", Yamana Shares issued pursuant to the Arrangement or upon exercise of Desert Sun Warrants and Desert Sun Options may be resold in each province and territory in Canada, subject in certain circumstances, to the usual conditions that no unusual effort has been made to prepare the market or create demand for the Yamana Shares and that no extraordinary commission or consideration is paid for the Yamana Shares. Subject to certain disclosure and regulatory requirements and to customary restrictions applicable to distributions of shares pursuant to "control distributions", Desert Sun Warrants may be resold in each province and territory in Canada, subject in certain circumstances, to the usual conditions that no unusual effort has been made to prepare the market or create demand for the Yamana Shares and that no extraordinary commission or consideration is paid for the Yamana Shares. UNITED STATES The Yamana Shares to be issued pursuant to the Arrangement (including those to be issued upon any subsequent exercise of Desert Sun Options and Desert Sun Warrants) have not been and will not be registered under U.S. Securities Act and will instead be issued in reliance on an exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereof. Section 3(a)(10) exempts securities issued in exchange for one or more outstanding securities from the general requirement of registration where the terms and conditions of the issuance and exchange of such securities 35 have been approved by any court of competent jurisdiction expressly authorized by law to grant such approval, after a hearing regarding the fairness of the terms and conditions of the issuance and exchange at which all persons to whom the securities will be issued have the right to appear. The Court is authorized to conduct a hearing at which the fairness of the terms and conditions of the Arrangement will be considered. The Court granted the Interim Order on March 1, 2006 and, subject to the approval of the Arrangement by Desert Sun Shareholders, a final hearing on the Arrangement will be held on April 4, 2006 by the Court. See "The Arrangement Agreement -- Court Approval and Completion of the Combination". The Yamana Shares to be issued in connection with the Arrangement will be freely transferable under United States federal securities laws and will not bear any restrictive legend imposed as a result of the operation of the U.S. Securities Act, except with respect to Yamana Shares held by persons who are deemed to be "affiliates" (as such term is defined under the U.S. Securities Act) of Desert Sun, Yamana or Yamana Subco, prior to the Arrangement or of Yamana or Amalco following the Arrangement. Persons who may be deemed to be affiliates of a company generally include individuals or entities that control, are controlled by, or are under common control with, such company and generally include executive officers and directors of such company as well as principal shareholders of such company. Yamana Shares acquired by persons who are deemed to be affiliates of Desert Sun, Yamana or Yamana Subco, prior to the Arrangement, and of Yamana or Amalco, following the Arrangement, may be resold by such persons only in transactions permitted by the applicable resale provisions of the U.S. Securities Act. Subject to certain limitations, such affiliates may immediately resell Yamana Shares outside the United States without registration under the U.S. Securities Act pursuant to Regulation S. Yamana Shares held by such affiliates may also be resold in compliance with the resale provisions of Rule 145(d)(1), (2), or (3) under the U.S. Securities Act or as otherwise permitted under the U.S. Securities Act. Rule 145(d)(1) generally provides that such affiliates may not sell the Yamana Shares received pursuant to the Arrangement unless pursuant to an effective registration statement or in accordance with the volume, current public information and manner of sale limitations of Rule 144. These limitations generally require that any sales made by an affiliate in any three-month period not exceed the greater of 1% of the outstanding Yamana Shares or, if the Yamana Shares are listed on a United States securities exchange, the average weekly trading volume over the four calendar weeks preceding the placement of the sell order, and that sales be made in unsolicited, open market "brokers' transactions" at times when certain information specified by the Rule 144 is publicly available with respect to Yamana. Rules 145(d)(2) and (3) generally provide that these limitations lapse for non-affiliates of Yamana after a period of one or two years, depending upon whether information continues to be publicly available with respect to Yamana. After the Arrangement, the Desert Sun Warrants and Desert Sun Options in each case exercisable for Yamana Shares, may be exercised only pursuant to an exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws. As a result, the Desert Sun Warrants and Desert Sun Options may only be exercised by a holder who represents that at the time of exercise the holder is not then located in the United States, is not a U.S. person, as defined in Rule 902 of Regulation S under the U.S. Securities Act, and is not exercising the Desert Sun Warrants or Desert Sun Options for the account or benefit of a U.S. person or a person in the United States, or the holder provides a legal opinion or other evidence reasonably satisfactory to Yamana to the effect that the exercise of the Desert Sun Warrants does not require registration under the U.S. Securities Act or state securities laws. In addition, any Yamana Shares issuable upon the exercise of the Desert Sun Warrants or Desert Sun Options in the United States or for the account or benefit of a U.S. person or a person in the United States will be "restricted securities" within the meaning of Rule 144 under the U.S. Securities Act, certificates representing such Yamana Shares will bear a legend to that effect, and such Yamana Shares may be resold only pursuant to an exemption from the registration requirements of the U.S. Securities Act and state securities laws, after providing an opinion of counsel or other documentation satisfactory to Yamana to such effect. Subject to certain limitations, the Desert Sun Warrants may be resold outside the United States without registration under the U.S. Securities Act pursuant to Regulation S. The foregoing discussion is only a general overview of certain requirements of United States securities laws applicable to the Yamana Shares received upon completion of the Arrangement. All holders of such securities are urged to consult with their own counsel to ensure that the resale of their securities complies with applicable securities legislation. 36 THE ARRANGEMENT AGREEMENT On February 22, 2006, Yamana, Desert Sun and Yamana Subco entered into the Arrangement Agreement, a copy of which has been filed and is available for viewing on SEDAR, and which has been incorporated by reference in this Proxy Circular. The following is a summary of the material terms of the Arrangement Agreement. This summary is qualified in its entirety by reference to the full text of the Arrangement Agreement. GENERAL The Arrangement Agreement is dated as of February 22, 2006 and is made among Desert Sun, Yamana and Yamana Subco. The Arrangement Agreement provides for the combination of the businesses of Desert Sun and Yamana by way of a plan of arrangement under the CBCA. EFFECTIVE DATE After obtaining the approval of Desert Sun Shareholders, the Final Order, and upon the other conditions in the Arrangement Agreement, including receipt of all regulatory approvals, being satisfied or waived, Desert Sun intends to send the Articles of Arrangement to the Director for endorsement and filing. The Arrangement will become effective when the Director issues the Certificate. EXCHANGE RATIO Under the Arrangement, Desert Sun will amalgamate with Yamana Subco, a newly- formed, wholly-owned subsidiary of Yamana, and each Desert Sun Shareholder will be entitled to receive 0.6 of a Yamana Share for each Desert Sun Share on the terms set out in the Plan of Arrangement. TREATMENT OF DESERT SUN WARRANTS AND DESERT SUN OPTIONS The terms of the Arrangement Agreement confirm that each Desert Sun Warrant shall entitle the holder to receive upon the exercise thereof, in lieu of the number of Desert Sun Shares otherwise issuable upon the exercise thereof, the number of Yamana Shares which the holder would have been entitled to receive as a result of the transactions contemplated by the Plan of Arrangement if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was theretofore entitled upon such exercise, at an exercise price equal to the current exercise price per Desert Sun Warrant exercised, with the effect that each Yamana Share issued upon exercise of Desert Sun Warrants will be issued at a price of $4.167. Each Desert Sun Option will entitle the holder to receive upon the exercise thereof, in lieu of the number of Desert Sun Shares otherwise issuable upon the exercise thereof, the number of Yamana Shares that the holder would have been entitled to receive as a result of the transactions contemplated by the Plan of Arrangement if, immediately prior to the Effective Time, such holder had been the registered holder of the number of Desert Sun Shares to which such holder was theretofore entitled upon such exercise, at a price per Yamana Share issued adjusted to reflect the Arrangement. Desert Sun Options shall continue to be governed by and be subject to the terms of the Desert Sun stock option plan and applicable agreement thereunder except to the extent that such Desert Sun Option will expire on the earlier of the expiry date for such option and six months after the Effective Date (instead of in ninety days as provided in the Stock Option Plan) if the holder thereof ceases to be an employee, consultant or director of Desert Sun as of the Effective Date and does not become an employee, consultant or director of Yamana or a material subsidiary thereof on that date. 37 Based on the number of Desert Sun Options and Desert Sun Warrants outstanding on February 28, 2006, upon completion of the Arrangement, holders of Desert Sun Warrants will be entitled to purchase an aggregate of approximately 11,976,724 Yamana Shares upon payment of $4.167 per Yamana Share (0.6 of a Yamana Share for each Desert Sun Warrant at an exercise price of $2.50 per warrant) issued at any time prior to 5:00 p.m. on November 20, 2008. Holders of Desert Sun Options will be entitled to purchase an aggregate of approximately 5,128,298 Yamana Shares at prices ranging from $0.63 to $4.77 per Yamana Share issued with the latest expiry date being January 3, 2011. Pursuant to the share compensation plan of Desert Sun, all Desert Sun Shares previously granted but not yet issued under the plan will automatically vest and be issued upon the change of control of Desert Sun, and participants under the share compensation plan will not have any continuing rights to receive Yamana Shares under the share compensation plan.

ADDITIONAL CONDITIONS PRECEDENT TO THE OBLIGATIONS OF DESERT SUN The obligations of Desert Sun to complete the Arrangement are subject to the satisfaction of certain additional conditions in its favour, including, among others, (i) the representations and warranties of Yamana under the Arrangement Agreement being true and correct, except where failure or breaches of representations and warranties would not either individually or in the aggregate in the reasonable judgement of Desert Sun have a Material Adverse Effect on Yamana; (ii) there having been no changes, effects, events, occurrences or states of facts that, either individually or in the aggregate, have, or could have, a Material Adverse Effect on Yamana; (iii) Yamana having complied in all material respects with its covenants in the Arrangement Agreement. 41 NON-SOLICITATION AND SUPERIOR PROPOSAL Pursuant to the Arrangement Agreement, Desert Sun has agreed that it will not, directly or indirectly, through any officer, director, employee, representative, advisor or agent of Desert Sun or the Desert Sun Subsidiary, or otherwise: (a) solicit, initiate or promote (including by way of furnishing information or entering into any form of agreement or understanding) any inquiries or proposals regarding any Acquisition Proposal or potential Acquisition Proposal; (b) participate in any discussions or negotiations regarding any Acquisition Proposal or potential Acquisition Proposal; (c) agree to, approve or recommend any Acquisition Proposal or potential Acquisition Proposal; (d) accept or enter into any agreement, understanding or arrangement related to any Acquisition Proposal or potential Acquisition Proposal; or make any public announcement or take any other action inconsistent with, or that could reasonably be likely to be regarded as detracting from, the recommendation of the directors of Desert Sun to approve the Combination. Notwithstanding the foregoing, nothing will prevent or restrict the Board of Directors from, prior to the approval of the Arrangement by Desert Sun Shareholders, considering or negotiating any unsolicited bona fide Acquisition Proposal that would be a Superior Proposal or from approving or recommending to Desert Sun Shareholders, or entering into any agreement in respect of, a Superior Proposal in accordance with the terms of the Arrangement Agreement. Desert Sun must notify Yamana within 24 hours of the receipt by any director or officer of Desert Sun of any Acquisition Proposal, any amendment to the foregoing, or any request for non-public information relating to Desert Sun or the Desert Sun Subsidiary. See "The Combination -- Non-Solicitation". Neither Desert Sun nor the directors thereof shall accept, approve or recommend or enter into any agreement in respect of an Acquisition Proposal on the basis that it would constitute a Superior Proposal, unless (i) Desert Sun has provided Yamana with a copy of the documents provided with any information not previously provided to Yamana; (ii) such Superior Proposal does not provide for the payment of any break, termination or other fees or expenses to the other party in the event that Desert Sun completes the Combination or any other similar transaction with Yamana or any of its affiliates agreed to prior to any termination of the Arrangement Agreement (provided that a Superior Proposal may provide for the payment of expenses to the other party in the event that Desert Sun and Yamana do not enter into an amended agreement in respect of the Superior Proposal, Yamana provides notice that it wishes the Meeting to proceed, a further Superior Proposal is subsequently made by another party and Yamana ultimately succeeds); (iii) Desert Sun has provided Yamana with a copy of the information containing such Acquisition Proposal; and (iv) five business days have elapsed from the later of the date on which Yamana received notice of the determination of the Board of Directors to accept, approve, recommend or enter into any agreement in respect of such Superior Proposal and the date Yamana received a copy of the Acquisition Proposal, and Yamana has not within such five business day period agreed to at least match the value per Desert Sun Share of such Superior Proposal. See "The Combination -- Superior Proposal". AMENDMENT AND WAIVER The Arrangement Agreement, including the Plan of Arrangement, may be amended by written agreement of the parties at any time before or after the Meeting without, subject to applicable law, further notice to or authorization on the part of the Desert Sun Shareholders and any such amendment may, without limitation, (i) change the time for the performance of any of the obligations or acts of any of the parties to the Arrangement Agreement; (ii) waive any inaccuracies in or modify any representation or warranty contained in the Arrangement Agreement or in any document delivered pursuant to the Arrangement Agreement; (iii) waive compliance with or modify any of the covenants in the Arrangement Agreement and waive or modify the performance of any of the obligations of any of the parties hereto; and (iv) waive compliance with or modify any condition under the Arrangement Agreement. TERMINATION AND TERMINATION FEES The Arrangement Agreement may be terminated at any time prior to the Effective Date: 1. by mutual written consent of the parties; 2. by either party if: a. a mutual condition or a condition in its favour is not satisfied; or 42 b. the Effective Date is not on or before the Completion Deadline, provided however, if the Arrangement has not been completed by such date because the Meeting has not been held due to the fault of Desert Sun, then Desert Sun shall not be entitled to terminate the Arrangement Agreement; or c. the Meeting is held and completed and the Desert Sun Shareholders do not approve the Arrangement Resolution; or 3. by Yamana or Yamana Subco if there is a Superior Proposal and the directors of Desert Sun withdraw or modify in any manner adverse to Yamana or Yamana Subco their approval or recommendation of the Arrangement, or shall fail, after being requested by Yamana in writing, to reaffirm its approval or recommendation of the Arrangement, or shall have accepted, approved, recommended or entered into any agreement in respect of any Superior Proposal. If Yamana terminates the Arrangement Agreement in connection with: 1. a Superior Proposal and the Board of Directors of Desert Sun has (i) withdrawn or modified in a manner adverse to Yamana their approval or recommendation of the Arrangement; (ii) failed, after being requested by Yamana in writing, to reaffirm its approval or recommendation of the Arrangement as promptly as possible, but in any event within two business days, or (iii) accepted, approved or recommended or entered into an agreement in respect of any Superior Proposal; 2. Desert Sun failing to satisfy, in any material respect, its covenants regarding non-solicitation and superior proposals, as described under the heading "The Arrangement Agreement -- Non-Solicitation and Superior Proposal"; 3. Desert Sun failing to submit the Arrangement for approval to the Desert Sun Shareholders, in accordance with the terms of the Arrangement Agreement, or failing to solicit proxies in connection therewith; then Desert Sun shall pay Yamana an amount in cash equal to $21.5 million. Desert Sun shall also have to pay such break fee if an Acquisition Proposal has been made to Desert Sun and made known to Desert Sun Shareholders generally and not withdrawn publicly prior to the Meeting, the Desert Sun Shareholders do not approve the Arrangement and Desert Sun completes an Acquisition Proposal with such third party within nine months following the termination of the Arrangement. Such payment shall be made within five days following the completion of the Acquisition Proposal. Desert Sun shall not be obligated to make more than one such termination payment. In addition, in the event that Desert Sun enters into an agreement to implement a Superior Proposal, Yamana may require that Desert Sun hold the Meeting, and place the Arrangement Resolution before the Desert Sun Shareholders for approval. INDEMNIFICATION AND INSURANCE Yamana covenants that all rights to indemnification or exculpation in favour of current and former officers and directors of Desert Sun and its subsidiaries as provided in their respective articles, by-laws, any agreement or directors' and officers' insurance policies will survive (or be replaced with substantially similar coverage by another provider) the completion of the Arrangement, in full force and effect for a period of five years, in the case of such insurance policies. EXPENSES The Arrangement Agreement provides that each of Desert Sun and Yamana shall pay its own expenses incurred in connection with the Combination. 43 RISK FACTORS Desert Sun Shareholders should carefully consider the following risk factors in evaluating whether to approve the Arrangement. These risk factors should be considered in conjunction with the other information included in this Proxy Circular. RISK FACTORS RELATING TO THE ARRANGEMENT FAILURE TO COMPLETE THE ARRANGEMENT COULD NEGATIVELY AFFECT DESERT SUN'S SHARE PRICE, FUTURE BUSINESS AND OPERATIONS Risks to which Desert Sun is subject relating to the Arrangement not being completed include: (a) the price of the Desert Sun Shares may decline to the extent that the relevant current market price reflects a market assumption that the Arrangement will be completed; (b) certain costs related to the Arrangement, such as legal, accounting and certain financial advisor fees incurred by Desert Sun, must be paid by Desert Sun even if the Arrangement is not completed. In addition, if the Arrangement is not completed, Desert Sun may be required to pay Yamana the Termination Fee. The Termination Fee could adversely affect Desert Sun's financial condition; and (c) if the Arrangement is terminated and the Board of Directors decides to seek another merger or business combination, there can be no assurance that it will be able to find a party willing to pay an equivalent or more attractive price than the price to be paid by Yamana pursuant to the Arrangement. In addition, Desert Sun employees may experience uncertainty about their future roles with Yamana until Yamana's strategies with respect to Desert Sun are announced and executed. This may adversely affect Desert Sun's ability to attract or to retain key management and personnel. RISKS ASSOCIATED WITH THE FIXED EXCHANGE RATIO Pursuant to the provisions of the Plan of Arrangement, each Desert Sun Share will be exchanged for 0.6 of a Yamana Share. The Exchange Ratio is fixed and it will not increase or decrease due to fluctuations in the market price of either the Yamana Shares or the Desert Sun Shares. The market value of the consideration that Desert Sun Shareholders will receive in the Arrangement will depend on the market price of the Yamana Shares on the Effective Date. If the market price of the Yamana Shares increases or decreases, the market value of the Yamana Shares that Desert Sun Shareholders will receive will correspondingly increase or decrease. Because the date that the Arrangement is completed will be later than the date of the Meeting, the price of the Yamana Shares on the Effective Date may be higher or lower than the price on the date of the Meeting. In addition, the number of Yamana Shares being issued in connection with the Arrangement will not change despite decreases or increases in the market price of Desert Sun Shares. Many of the factors that affect the market price of the Yamana Shares and the Desert Sun Shares are beyond the control of Yamana and Desert Sun, respectively. These factors include fluctuations in commodity prices, most importantly gold and copper, fluctuations in currency exchange rates, changes in the regulatory environment, adverse political developments, prevailing conditions in the capital markets and interest rate fluctuations. DESERT SUN DIRECTORS AND EXECUTIVE OFFICERS MAY HAVE INTERESTS IN THE ARRANGEMENT THAT ARE DIFFERENT FROM THOSE OF DESERT SUN SHAREHOLDERS In considering the recommendation of the Desert Sun Board of Directors to vote in favour of the Arrangement Resolution, Desert Sun Shareholders should be aware that certain members of the Desert Sun Board of Directors and management team have agreements or arrangements that provide them with interests in the Arrangement that differ from, or are in addition to, those of Desert Sun Shareholders generally. See "The Combination -- Interests of Certain Persons in the Arrangement". 44 UNCERTAINTIES ASSOCIATED WITH THE ARRANGEMENT The Arrangement will involve the integration of companies that previously operated independently. An important factor in the success of the Arrangement will be the ability of the management of the combined entity in managing Desert Sun and, if appropriate, integrating all or part of the operations, systems, technologies and personnel of the two companies following the completion of the transaction. The Arrangement and/or the integration of the two businesses can result in unanticipated operational problems and interruptions, expenses and liabilities, the diversion of management attention and the loss of key employees, customers or suppliers. There can be no assurance that the Arrangement and business integration will be successful or that the combination will not adversely affect the business, financial condition or operating results of the combined entity. In addition, the combined entity may incur charges related to the Arrangement and related to integrating the two companies. There can be no assurance that the combined company will not incur additional material charges in subsequent quarters to reflect additional costs associated with the Arrangement or that that the benefits expected from the Arrangement will be realized. RISK FACTORS RELATING TO YAMANA Please refer to Exhibit B -- "Yamana Gold Inc. -- Risk Factors" for a discussion of risk factors relating to the business of Yamana and an investment in Yamana Shares. CERTAIN TAX CONSIDERATIONS TO DESERT SUN SHAREHOLDERS CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS The following is a summary of the principal Canadian federal income tax considerations of the Arrangement generally applicable to Desert Sun Shareholders who, for the purposes of the Tax Act and at all relevant times, (i) deal at arm's length with both Yamana and Desert Sun, (ii) are not affiliated with either Yamana or Desert Sun, and (iii) hold their Desert Sun Shares as capital property. Desert Sun Shares will generally be considered capital property to a Desert Sun Shareholder unless the Desert Sun Shareholder holds the Desert Sun Shares in the course of carrying on a business or has acquired the Desert Sun Shares in a transaction or transactions considered to be an adventure in the nature of trade. Desert Sun Shareholders who are resident in Canada for purposes of the Tax Act and whose Desert Sun Shares might not otherwise qualify as capital property may be entitled to make the irrevocable election provided by subsection 39(4) of the Tax Act to have such Desert Sun Shares and every "Canadian security" (as defined in the Tax Act) owned by such holder in the taxation year of the election and in all subsequent taxation years deemed to be capital property. This summary does not apply to a Desert Sun Shareholder that is a "financial institution" within the meaning of subsection 142.2(l) of the Tax Act. This summary is based upon the current provisions of the Tax Act, the regulations thereunder, and Desert Sun's understanding of the current published administrative practices of the CRA as of the date hereof. This summary also takes into account all specific proposals to amend the Tax Act which have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Proposed Amendments"). However, no assurances can be given that the Proposed Amendments will be enacted in the form proposed, or at all. Except for the Proposed Amendments, this summary does not otherwise take into account or anticipate any changes in law, whether by judicial, governmental or legislative decision or action, or changes in the administrative practices of the CRA. This summary also does not take into account provincial, territorial or foreign income tax legislation or considerations, which may differ from the Canadian federal income tax considerations summarized herein. This summary is of a general nature only and is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal, business or tax advice or representations to any particular Desert Sun Shareholder. Accordingly, Desert Sun Shareholders should consult their own tax advisors for advice regarding the income tax consequences of the Arrangement having regard to their particular circumstances. This summary is not applicable to a Desert Sun Shareholder who acquired their Desert Sun Shares pursuant to the exercise of an employee stock option and any such Desert Sun Shareholder should consult their tax advisor with respect to the tax consequences of the Arrangement. 45 DESERT SUN SHAREHOLDERS RESIDENT IN CANADA The following portion of the summary is generally applicable to a Desert Sun Shareholder who, at all relevant times, for the purposes of the Tax Act and any applicable income tax convention, is, or is deemed to be, resident in Canada. ARRANGEMENT -- EXCHANGE OF SHARES A Desert Sun Shareholder who receives Yamana Shares in exchange for its Desert Sun Shares under the Arrangement will realize neither a capital gain nor a capital loss as a result of the Arrangement. Such a Desert Sun Shareholder will be considered to have disposed of its Desert Sun Shares for proceeds of disposition equal to the aggregate adjusted cost base of its Desert Sun Shares immediately before the Arrangement and to have acquired Yamana Shares at an aggregate cost equal to such proceeds of disposition. For the purpose of determining at any time the adjusted cost base of Yamana Shares acquired by a Desert Sun Shareholder under the Arrangement, the cost of such Yamana Shares must be averaged with the adjusted cost base to the holder of all other Yamana Shares held by the holder at that time. DISPOSITION OF YAMANA SHARES A holder who disposes of Yamana Shares will realize a capital gain (or capital loss) to the extent that the proceeds of disposition thereof, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of such shares to such holder. The income tax treatment of capital gains and capital losses is discussed in greater detail below under the subheading "Taxation of Capital Gains and Capital Losses". TAXATION OF CAPITAL GAINS AND CAPITAL LOSSES One-half of capital gains will be taxable capital gains which must be included in income and one-half of capital losses will be allowable capital losses that may be deducted against taxable capital gains realized in the year of disposition. Subject to the detailed rules contained in the Tax Act, any unused allowable capital loss may be applied to reduce net taxable capital gains realized by the holder in the three preceding and in all subsequent taxation years. Recognition of capital losses otherwise realized may be denied in various circumstances set out in the Tax Act. The amount of any capital loss realized by a corporate holder on a disposition of Yamana Shares may be reduced by the amount of dividends received, if any, or deemed to be received on the shares, to the extent and under the circumstances provided in the Tax Act. Similar rules may apply where a corporation is a member of a partnership or a beneficiary of a trust that owns the shares or where a trust or partnership of which a corporation is a beneficiary or a member, respectively, is a member of a partnership or a beneficiary of a trust that owns the shares. A holder that is a Canadian-controlled private corporation throughout the relevant taxation year may be subject to an additional refundable tax of 6 (2)/3% on taxable capital gains. This additional tax will be refunded to the holder at the rate of $1 for every $3 of taxable dividends paid while it is a private corporation. Where the holder is an individual or a trust, other than certain trusts, the realization of a capital gain may result in a liability for alternative minimum tax under the Tax Act. ARRANGEMENT -- DISSENTING DESERT SUN SHAREHOLDERS A Dissenting Shareholder who receives from Yamana a payment in an amount equal to the fair value of the Dissenting Shareholder's Desert Sun Shares will be considered to have disposed of the Desert Sun Shares for proceeds of disposition equal to the amount received by the Dissenting Shareholder (less the amount of any interest awarded by a court in respect of such payment). Such a disposition of Desert Sun Shares by a Dissenting Shareholder will generally result in a capital gain (or capital loss) to the extent that the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to the Dissenting Shareholder of those Desert Sun Shares immediately before the 46 disposition. The income tax treatment of capital gains and capital losses is discussed in greater detail above under the subheading "Taxation of Capital Gains and Capital Losses". Any interest awarded by a court to a Dissenting Shareholder will be included in such Dissenting Shareholder's income for purposes of the Tax Act. DESERT SUN SHAREHOLDERS NOT RESIDENT IN CANADA The following summary is generally applicable to a Desert Sun Shareholder who, at all relevant times, for the purposes of the Tax Act and any applicable income tax convention, is neither resident nor deemed to be resident in Canada, and who does not use or hold and is not deemed to use or hold Desert Sun Shares in carrying on a business in Canada (a "Non-Resident Shareholder"). Special rules, which are not discussed in this summary, may apply to a non-resident that is an insurer carrying on business in Canada and elsewhere. ARRANGEMENT -- EXCHANGE OF SHARES A Non-Resident Shareholder who exchanges Desert Sun Shares for Yamana Shares under the Arrangement will generally be subject to the same tax consequences as a Canadian resident holder on the Arrangement, as discussed above. Accordingly, a Non-Resident Shareholder who receives Yamana Shares in exchange for Desert Sun Shares on the amalgamation will generally realize neither a capital gain nor a capital loss. DISPOSITION OF YAMANA SHARES A Non-Resident Shareholder who disposes of Yamana Shares will not be subject to tax under the Tax Act on any gain arising on the disposition of such shares unless such shares constitute "taxable Canadian property" of the holder for the purposes of the Tax Act. In addition, if such shares do constitute taxable Canadian property, the Non-Resident Shareholder may be exempt from tax under an applicable income tax convention. 47 Generally, Yamana Shares will not be taxable Canadian property of a Non-Resident Shareholder at a particular time provided that (i) the Yamana Shares are not deemed to be taxable Canadian property to the holder, and (ii) the Yamana Shares are listed on a prescribed stock exchange (which currently includes the TSX) and the holder, persons with whom the holder does not deal at arm's length, or the holder together with such persons, has not owned 25% or more of the issued shares of any class or series of the capital stock of Yamana at any time within the 60 month period immediately preceding the particular time. Any Yamana Shares received by a Non-Resident Shareholder in exchange for Desert Sun Shares which constitute taxable Canadian property to the Non-Resident Shareholder will be deemed to be taxable Canadian property to the Non-Resident Shareholder. Generally, a Non-Resident Shareholder who realizes a capital gain on a disposition of Yamana Shares which constitute taxable Canadian property of the holder and which is not exempt from tax under an applicable income tax convention will be subject to the tax treatment described above under the subheading "Desert Sun Shareholders Resident in Canada -- "Taxation of Capital Gains and Capital Losses". ARRANGEMENT -- DISSENTING NON-RESIDENT SHAREHOLDERS A Non-Resident Shareholder who is a Dissenting Shareholder and who receives from Yamana the fair value of such Non-Resident Shareholder's Desert Sun Shares will not be subject to tax under the Tax Act in respect of such disposition of Desert Sun Shares provided such shares do not constitute "taxable Canadian property" of the Non-Resident Shareholder. See above under the subheading "Desert Sun Shareholders Not Resident in Canada, Disposition of Yamana Shares" for a general discussion of the tax treatment of capital gains realized on a disposition of Desert Sun Shares which constitute taxable Canadian property to the holder. Any interest paid to a Non-Resident Shareholder consequent upon the exercise of dissent rights will be subject to Canadian withholding tax at a rate of 25%, unless the rate is reduced under the provisions of an applicable income tax convention. Non-Resident Shareholders who are contemplating exercising their dissent rights should consult their own tax advisors. CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES Notice Pursuant To IRS Circular 230: Anything contained in this Proxy Circular concerning any U.S. federal tax issue is not intended or written to be used, and it cannot be used by a U.S. Holder (as defined below), for the purpose of avoiding U.S. federal tax penalties under the Internal Revenue Code. This summary was written to support the promotion or marketing of the transactions or matters addressed by this Proxy Circular. Each U.S. Holder should seek U.S. federal tax advice based on such U.S. Holder's particular circumstances from an independent tax advisor. The following summary describes the material U.S. federal income tax considerations generally applicable to U.S. Holders of Desert Sun Shares who exchange their Desert Sun Shares for Yamana Shares under the Arrangement and U.S. Holders of Desert Sun Shares who exercise their right to dissent in accordance with the dissent procedures set out in Exhibit I -- "Dissent Rights". This summary is based upon the Internal Revenue Code of 1986, as amended (the "Code"), proposed, temporary and final U.S. Treasury regulations under the Code, Internal Revenue Service ("IRS") rulings and judicial decisions, all as in effect as of the date of this Proxy Circular and all of which are subject to change (possibly with retroactive effect) or to differing interpretations. This summary applies only to holders of Desert Sun Shares that hold their Desert Sun Shares, and will hold any Yamana Shares that they receive under the Arrangement, as capital assets within the meaning of Section 1221 of the Code. This summary does not discuss all aspects of U.S. federal income taxation that may be relevant to a particular holder of Desert Sun Shares in light of such holder's particular circumstances or to holders of Desert Sun Shares subject to special treatment under the U.S. federal income tax laws, including: o banks, insurance companies, trusts and financial institutions; o tax-exempt organizations; 48 o mutual funds; o persons that have a functional currency other than the U.S. dollar; o traders in securities who elect to apply a mark-to-market method of accounting; o dealers in securities or foreign currency; o holders of Desert Sun Shares who received their shares in compensatory transactions; o holders of Desert Sun Shares who hold their shares as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment; o holders of Desert Sun Options or Desert Sun Warrants; and o holders who will hold 5% or more of the Yamana Shares, either directly, indirectly through one or more entities, or as a result of certain constructive ownership rules of the Code, following the exchange of Desert Sun Shares for Yamana Shares under the Arrangement. For purposes of this summary, a U.S. Holder is: o an individual who is a U.S. citizen or resident alien for U.S. federal income tax purposes; o a corporation, or entity classified as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States, any state thereof, or the District of Columbia; o an estate that is subject to U.S. federal income tax on its worldwide income; or o a trust if (i) a U.S. court is able to exercise supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (ii) the trust has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes. If a partnership holds Desert Sun Shares, the U.S. federal income tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partners of partnerships that hold Desert Sun Shares should consult their tax advisors regarding the U.S. federal income tax consequences to them of the Arrangement. PASSIVE FOREIGN INVESTMENT COMPANY RULES Special U.S. federal income tax rules will apply to U.S. Holders if Desert Sun currently is or has been a passive foreign investment company (a "PFIC") at any time during which the U.S. Holder has held Desert Sun Shares. A non-U.S. corporation generally is classified as a PFIC for U.S. federal income tax purposes in any taxable year if, either (i) at least 75% of its gross income is "passive" income (the "income test"), or (ii) on average at least 50% of the gross value of its assets is attributable to assets that produce passive income or are held for the production of passive income (the "asset test"). For purposes of the income test and the asset test, if a non-U.S. corporation owns, directly or indirectly, at least 25% (by value) of the stock of another corporation, the non-U.S. corporation will be treated as if it held its proportionate share of the assets of the latter corporation and received directly its proportionate share of the income of that latter corporation. Passive income generally includes dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related person), certain net gains from the sales of commodities such as oil and natural gas, annuities and gains from assets that produce passive income. Passive income does not include, however, any income that is interest, a dividend or a rent or royalty received or accrued from a related person to the extent that the amount is properly allocable to income of the related person that is not passive income. For these purposes, a related person includes a subsidiary controlled by the non-U.S. corporation, where control means ownership, directly or indirectly, 49 of stock possessing more than 50% of the total voting power of all classes of stock entitled to vote or of the total value of the stock of a corporation. The Code and applicable U.S. Treasury regulations exclude active business gains from transactions in commodities from the definition of passive income if substantially all of the non-U.S. corporation's commodities are stock in trade or inventory, depreciable property used in a trade or business, or supplies regularly used or consumed in a trade or business. Under the Code, if a non-U.S. corporation is a PFIC in any taxable year that a U.S. person holds shares, the non-U.S. corporation generally is considered a PFIC with respect to the U.S. person for all subsequent years after the first taxable year in the U.S. person's holding period in which the non-U.S. corporation was a PFIC. A U.S. person who holds shares of a PFIC is taxed at ordinary income tax rates on any gain realized on the sale or exchange of the shares and on any "excess distributions" received. Excess distributions are amounts received by a U.S. person with respect to its shares in any taxable year that exceed 125% of the average distributions received by the U.S. person in the shorter of either the three previous years or the U.S. person's holding period for the shares before the current taxable year. Gain and excess distributions are allocated ratably to each day that the U.S. person held shares. Amounts allocated to the current taxable year and to years before the non-U.S. corporation became a PFIC are treated as ordinary income. In addition, amounts allocated to each taxable year beginning with the year the non-U.S. corporation first became a PFIC are taxed at the highest rate in effect for that year on ordinary income. The tax is subject to an interest charge at the rate applicable to underpayments of income tax. Under certain circumstances, a U.S. person may make certain elections to mitigate some of the adverse U.S. federal income tax consequences of holding shares of a PFIC. U.S. persons generally are required to file IRS Form 8621 for each year in which they hold shares of a PFIC. Desert Sun believes that it may have been a PFIC for one or more years prior to 2005 since it had no income other than passive income. THE ARRANGEMENT For U.S. federal income tax purposes, Yamana and Desert Sun have agreed to treat the Arrangement as a reorganization under the provisions of Section 368(a) of the Code. Even if the Arrangement qualifies as a reorganization, however, the PFIC rules discussed in the preceding section may require U.S. Holders who have held Desert Sun Shares at any time during which Desert Sun was a PFIC to recognize taxable gain (but not loss) on the exchange of their Desert Sun Shares for Yamana Shares, as discussed below. U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them of the Arrangement. No legal opinion from U.S. legal counsel or ruling from the IRS has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the Arrangement to U.S. Holders. Accordingly, there can be no assurance that the Arrangement will qualify as a reorganization under the provisions of Section 368(a) of the Code or that the IRS will not challenge the status of the Arrangement as a reorganization. The requirements that must be satisfied in order for the Arrangement to qualify as a reorganization are complex, and each U.S. Holder should consult its own tax advisor regarding these requirements. Except as discussed under "Treatment if the Arrangement does not qualify as a reorganization", the remainder of this discussion assumes that the Arrangement will qualify as a reorganization under the provisions of Section 368(a) of the Code for U.S. federal income tax purposes. TREATMENT IF DESERT SUN IS A PFIC WITH RESPECT TO A U.S. HOLDER The discussion in this section assumes that Desert Sun is or has been a PFIC with respect to a U.S. Holder at any time during which a U.S. Holder has held Desert Sun Shares and that such U.S. Holder has not made a timely qualified electing fund ("QEF") election with respect to Desert Sun. The exchange of Desert Sun Shares for Yamana Shares under the Arrangement should be a taxable transaction to a U.S. Holder as long as Yamana is not a PFIC for 2006. In such case, a U.S. Holder should recognize gain upon exchanging its Desert Sun Shares for Yamana Shares. Such gain should be equal to the difference between the fair market value of the Yamana Shares received in the Arrangement and the U.S. Holder's adjusted tax basis in the Desert Sun Shares exchanged in 50 the Arrangement. Such gain should be recognized on a share-by-share basis and should be taxable as an "excess distribution" under the PFIC rules. An excess distribution should be allocated ratably to each day that the U.S. Holder held Desert Sun Shares. Amounts allocated to the current taxable year and to years before Desert Sun became a PFIC should be treated as ordinary income. In addition, amounts allocated to each taxable year beginning with the year Desert Sun first became a PFIC should be taxed at the highest rate in effect for that year on ordinary income. The tax should be subject to an interest charge at the rate applicable to underpayments of income tax. A U.S. Holder generally should not be permitted to recognize a loss on the exchange of Desert Sun Shares for Yamana Shares under the Arrangement. The U.S. Holder's basis in the Yamana Shares received should be adjusted to reflect the gain recognized. If, contrary to Yamana's current expectation (discussed below), Yamana is determined to be a PFIC for 2006, and Desert Sun has also been a PFIC at any time during which a U.S. Holder has held Desert Sun Shares, such a U.S. Holder of Desert Sun Shares should not be required to recognize gain on the exchange of its Desert Sun Shares for Yamana Shares under the Arrangement. The aggregate adjusted tax basis of the Yamana Shares received under the Arrangement should be equal to the aggregate adjusted tax basis of the Desert Sun Shares surrendered for the Yamana Shares. The holding period of the Yamana Shares received should include the period during which the U.S. Holder held the Desert Sun Shares. The treatment of any U.S. Holders who have properly made a "mark-to-market" election with respect to their Desert Sun Shares is unclear. Such U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them of the Arrangement. A U.S. Holder of Desert Sun Shares that exercises its right to dissent in accordance with the dissent procedures set out in Exhibit I -- "Dissent Rights" generally will recognize gain or loss measured by the difference between the amount of cash received and the adjusted tax basis of the Desert Sun Shares surrendered. Such gain, if any, will be taxable in the manner described above in the second paragraph of this section. If a U.S. Holder of Desert Sun Shares that exercises its right to dissent receives any interest, such interest will be subject to Canadian withholding tax. The amount of such interest, before reduction for Canadian withholding tax, generally will be taxable to a U.S. Holder as ordinary income at the time it is paid or accrued in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes. Such interest will be income from sources without the United States, and for taxable years beginning on or before December 31, 2006, generally will be "high withholding tax interest" for U.S. foreign tax credit limitation purposes as long as Canadian tax is withheld at a rate of at least 5%. TREATMENT IF DESERT SUN IS NOT A PFIC WITH RESPECT TO A U.S. HOLDER If Desert Sun has not been a PFIC at any time during which a U.S. Holder has held Desert Sun Shares, the U.S. Holder of Desert Sun Shares should not be required to recognize gain on the exchange of its Desert Sun Shares for Yamana Shares under the Arrangement. The aggregate adjusted tax basis of the Yamana Shares received under the Arrangement should be equal to the aggregate adjusted tax basis of the Desert Sun Shares surrendered for the Yamana Shares. The holding period of the Yamana Shares received should include the period during which the U.S. Holder held the Desert Sun Shares. A U.S. Holder of Desert Sun Shares that exercises its right to dissent in accordance with the dissent procedures set out in Exhibit I -- "Dissent Rights" generally will recognize gain or loss measured by the difference between the amount of cash received and the adjusted tax basis of the Desert Sun Shares surrendered. Such gain or loss will generally be a capital gain or loss, and will generally be long-term if, at the time the Desert Sun Shares are exchanged, the U.S. Holder has held the Desert Sun Shares for more than one year. Net long-term capital gains of non-corporate U.S. Holders, including individuals, are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder recognizes generally will be treated as income or loss from sources within the United States for U.S. foreign tax credit limitation purposes. If a U.S. Holder of Desert Sun Shares that exercises its right to dissent receives any interest, such interest will be subject to Canadian withholding tax. The amount of such interest, before reduction for Canadian withholding tax, generally will be taxable to a U.S. Holder as ordinary income at the time it is paid or accrued in accordance with the U.S. Holder's 51 regular method of accounting for U.S. federal income tax purposes. Such interest will be income from sources outside the United States, and for taxable years beginning on or before December 31, 2006, generally will be "high withholding tax interest" for U.S. foreign tax credit limitation purposes as long as Canadian tax is withheld at a rate of at least 5%. TREATMENT IF THE ARRANGEMENT DOES NOT QUALIFY AS A REORGANIZATION If the Arrangement does not qualify as a reorganization under the provisions of Section 368(a) of the Code and Desert Sun has been a PFIC at any time during which a U.S. Holder has held Desert Sun Shares, a U.S. Holder generally will recognize gain or loss equal to the difference between the fair market value of the Yamana Shares received in the Arrangement and the adjusted tax basis in the Desert Sun Shares exchanged in the Arrangement. Such gain, if any, will be taxable in the manner described above in the second paragraph under "Treatment if Desert Sun is a PFIC with respect to a U.S. Holder. If the Arrangement does not qualify as a reorganization under the provisions of Section 368(a) of the Code and Desert Sun has not been a PFIC at any time during which a U.S. Holder has held Desert Sun Shares, a U.S. Holder generally will recognize gain or loss in an amount equal to the difference, between the fair market value of the Yamana Shares received in the Arrangement and the tax basis in the Desert Sun Shares exchanged in the Arrangement. Such gain or loss will generally be a capital gain or loss, and will generally be long-term if, at the time the Desert Sun Shares are exchanged, the U.S. Holder has held the Desert Sun Shares for more than one year. Net long-term capital gains of non-corporate U.S. Holders, including individuals, are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder recognizes generally will be treated as income or loss from sources within the United States for U.S. foreign tax credit limitation purposes. INFORMATION REPORTING AND RECORDKEEPING REQUIREMENTS Certain information reporting requirements on IRS Form 8621 generally will apply to a U.S. Holder under the Arrangement with respect to whom Desert Sun is a PFIC if the U.S. Holder exchanges its Desert Sun Shares for Yamana Shares or otherwise disposes of its Desert Sun Shares. Special reporting requirements will also apply if a U.S. Holder with respect to whom Desert Sun is a PFIC exchanges its Desert Sun Shares for Yamana Shares and Yamana is a PFIC. In addition, assuming the Arrangement qualifies as a reorganization under the provisions of the Section 368(a) of the Code, each U.S. Holder of Desert Sun Shares that receives Yamana Shares under the Arrangement generally will be required to file a statement with its U.S. federal income tax return providing its basis in the Desert Sun Shares surrendered and the fair market value of the Yamana Shares received, and to retain permanent records of this information relating to the Arrangement. U.S. Holders should consult their tax advisors regarding the information reporting and recordkeeping requirements applicable to them in connection with the Arrangement. OWNERSHIP OF YAMANA SHARES DISTRIBUTIONS ON YAMANA SHARES Subject to the PFIC rules discussed below, the gross amount of any cash distribution with respect to Yamana Shares (before reduction for Canadian withholding taxes) will be taxable to U.S. Holders of Yamana Shares as a dividend to the extent of Yamana's current and accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of any cash distribution exceeds Yamana's current and accumulated earnings and profits, as determined under U.S. federal income tax principles, such distribution will first be treated as a tax-free return of capital, causing a reduction in the adjusted basis of the Yamana Shares (thereby increasing the amount of gain or decreasing the amount of loss that a U.S. Holder would recognize on a subsequent disposition of Yamana Shares). Any balance in excess of the adjusted basis will be treated as capital gain. Subject to certain limitations, dividends paid to noncorporate U.S. Holders, including individuals, may be eligible for a reduced rate of U.S. federal income taxation if Yamana is deemed to be a "qualified foreign corporation" for U.S. federal income tax purposes. A qualified foreign corporation includes a non-U.S. corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that includes an exchange of information program and 52 that the U.S. Treasury Department has determined to be satisfactory for purposes of the qualified dividend provisions of the Code. The U.S. Treasury Department has determined that the income tax treaty between the United States and Canada is satisfactory for purposes of the qualified dividend provisions of the Code. A non-U.S. corporation will also be treated as a qualified foreign corporation with respect to a dividend paid if the stock with respect to which such dividend was paid is regularly traded on an established securities market in the U.S. A qualified foreign corporation does not include a non-U.S. corporation that is a PFIC for the taxable year in which a dividend is paid or for the preceding taxable year. Dividends paid on the Yamana Shares should be eligible for this reduced rate of U.S. federal income taxation as long as Yamana is not a PFIC and either Yamana is eligible for the benefits of the income tax treaty between the United States and Canada or the Yamana Shares are regularly traded on an established U.S. securities market. Distributions will be includable in a U.S. Holder's gross income on the date actually or constructively received by the U.S. Holder. These dividends will not be eligible for the dividends received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations. If Yamana pays dividends on the Yamana Shares in Canadian dollars, the U.S. dollar value of such dividends should be calculated by reference to the exchange rate prevailing on the date of actual or constructive receipt of the dividend, regardless of whether the Canadian dollars are converted into U.S. dollars at that time. If Canadian dollars are converted into U.S. dollars on the date of actual or constructive receipt of such dividends, a U.S. Holder's tax basis in such Canadian dollars will be equal to their U.S. dollar value on that date and, as a result, the U.S. Holder generally should not be required to recognize any foreign currency exchange gain or loss. Any gain or loss recognized on a subsequent conversion or other disposition of the Canadian dollars generally will be treated as U.S. source ordinary income or loss. A U.S. Holder may be entitled to claim a U.S. foreign tax credit for or deduct Canadian taxes that are withheld on dividends received by the U.S. Holder, subject to applicable limitations in the Code. For taxable years beginning on or before December 31, 2006, dividends paid on the Yamana Shares generally will constitute "passive income" or, in the case of certain U.S. Holders, "financial services income" and will be treated as income from sources without the United States for U.S. foreign tax credit limitation purposes. For taxable years beginning after December 31, 2006, such dividends generally will constitute "passive category income" or "general category income" for U.S. foreign credit limitation purposes. The amount of foreign income taxes that may be claimed as a credit in any year is subject to complex limitations and restrictions, which must be determined on an individual basis by each holder. U.S. Holders are urged to consult their tax advisors regarding the availability of the U.S. foreign tax credit in their particular circumstances. SALE, EXCHANGE OR OTHER DISPOSITION OF YAMANA SHARES Subject to the PFIC rules discussed below, upon the sale, exchange or other disposition of Yamana Shares, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized upon the sale, exchange or other disposition of Yamana Shares and the U.S. Holder's adjusted tax basis in the Yamana Shares. The capital gain or loss generally will be long-term capital gain or loss if, at the time of sale, exchange or other disposition, the U.S. Holder has held the Yamana Shares for more than one year. Net long-term capital gains of noncorporate U.S. Holders, including individuals, are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss that a U.S. Holder recognizes generally will be treated as gain or loss from sources within the United States for U.S. foreign tax credit limitation purposes. PASSIVE FOREIGN INVESTMENT COMPANY RULES As discussed under "Exchange of Desert Sun Shares for Yamana Shares -- Passive Foreign Investment Company Rules", above, special rules apply in determining whether a non-U.S. corporation is a PFIC. Yamana anticipates that it should be considered to be engaged in the active conduct of a commodities business (as discussed above), and does not expect to be a PFIC for 2006. Because this conclusion is a factual determination that is made annually and is subject to change, there can be no assurances that Yamana will not be a PFIC for 2006 or any future taxable year. Under the Code, if Yamana were considered to be a PFIC in any taxable year that a U.S. Holder held Yamana Shares, Yamana generally would be considered a PFIC for all taxable years that such U.S. Holder held Yamana Shares after the first taxable year that Yamana was considered to be a PFIC. 53 In general, if Yamana were a PFIC, a U.S. Holder would be taxed at ordinary income tax rates on any gain realized on the sale or exchange of the Yamana Shares and on any "excess distributions" received. Excess distributions are amounts received by a U.S. Holder with respect to Yamana Shares in any taxable year that exceed 125% of the average distributions received by the U.S. Holder in the shorter of either the three previous years or the U.S. Holder's holding period for the Yamana Shares before the current taxable year. Gain and excess distributions would be allocated ratably to each day that that U.S. Holder held Yamana Shares. Amounts allocated to the current taxable year and to years before Yamana became a PFIC would be treated as ordinary income. In addition, amounts allocated to each taxable year beginning with the year Yamana first became a PFIC would be taxed at the highest rate in effect for that year on ordinary income. The tax would be subject to an interest charge at the rate applicable to underpayments of income tax. Rather than being subject to this tax regime, a U.S. Holder could: o make a QEF election to be taxed currently on its pro rata portion of Yamana's income and gain, whether or not such income or gain were distributed in the form of dividends or otherwise; or o make a "mark-to-market" election and thereby agree, for the year of the election and each subsequent tax year, to recognize ordinary gain or, to the extent of any prior ordinary gain, ordinary loss based on the increase or decrease in market value for such taxable year. A U.S. Holder's basis in its shares would be adjusted to reflect any such income or loss amounts. A QEF election generally should be made for the first taxable year in which a corporation is a PFIC. If Yamana were a PFIC, a U.S. Holder would be required to file IRS Form 8621 for each year in which the U.S. Holder held Yamana Shares. U.S. Holders are strongly urged to consult their own tax advisors regarding possible classification of Yamana as a PFIC and the adverse U.S. federal income tax consequences that would result from such classification. INFORMATION REPORTING AND BACKUP WITHHOLDING In general, unless a U.S. Holder belongs to a category of certain exempt recipients (such as corporations), information reporting requirements will apply to dividends as well as proceeds of sales of Yamana Shares that are effected through the U.S. office of a broker or the non-U.S. office of a broker that has certain connections with the United States. Backup withholding may apply to these payments if a U.S. Holder fails to provide a correct taxpayer identification number or certification of exempt status, fails to report in full dividend and interest income or, in certain circumstances, fails to comply with applicable certification requirements. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against a U.S. Holder's U.S. federal income tax, provided the U.S. Holder furnishes the required information to the IRS in a timely manner. ELIGIBILITY FOR INVESTMENT IN CANADA OF YAMANA SHARES Provided Yamana Shares are listed on a prescribed stock exchange (which currently includes the TSX and the AMEX), Yamana Shares will be qualified investments under the Tax Act for trusts governed by RRSPs, RRIFs, DPSPs and RESPs. 54 ANNUAL BUSINESS TO BE CONSIDERED BY DESERT SUN SHAREHOLDERS ELECTION OF DIRECTORS The directors of Desert Sun are elected annually and hold office until the next annual meeting of shareholders of Desert Sun, or any adjournment thereof, or until their successors are elected or appointed unless a director's office is earlier vacated under the articles of Desert Sun or the CBCA or he or she becomes disqualified to act as a director. The Board of Directors currently consists of six directors (the "Nominees"). The following table provides the names of the Nominees and information concerning such Nominees. The persons in the enclosed form of proxy intend to vote for the election of the Nominees. Desert Sun management does not contemplate that any of the Nominees will be unable to serve as a director. If prior to the Meeting any of such Nominees is unable to or unwilling to serve, the persons named in the accompanying form of proxy will vote for another nominee or nominees in their discretion if additional nominations are made at the Meeting.

For the year ended December 31, 2005, Desert Sun paid McGovern, Hurley, Cunningham, LLP total fees of $165,800. These fees consisted of $154,900 for audit-related services, $10,900 for tax compliance and advisory services and no other fees. Audit-related fees include fees relating to the preparation of prospectuses and consultations regarding financial accounting and reporting standards. SPECIAL BUSINESS TO BE CONSIDERED BY DESERT SUN SHAREHOLDERS In order for the Arrangement to be effected, the Desert Sun Shareholders will be asked to consider and, if deemed advisable, to approve the Arrangement Resolution at the Meeting. The Arrangement Resolution (the text of which appears as Exhibit F to this Proxy Circular) must be approved by an affirmative vote of not less than two-thirds of the votes cast in respect thereof by Desert Sun Shareholders at the Meeting and a simple majority of the votes cast by disinterested Desert Sun Shareholders at the Meeting. As of the date hereof, Mr. Bharti owns or controls, directly or indirectly, 1,149,999 Desert Sun Shares (1.1%), which Desert Sun Shares will be excluded for the purpose of the majority of the vote of the disinterested Desert Sun Shareholders. In the absence of a specification made in the form of proxy to the contrary, the persons named in the form of proxy intend to vote IN FAVOUR OF the Arrangement Resolution. 56 EXHIBIT A DESERT SUN MINING CORP.

NON-GAAP MEASURES "Cash cost" figures are calculated in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading North American gold producers. The Gold Institute ceased operations in 2002, but the standard is the accepted standard of reporting cash costs of production in North America. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Total cash costs include mine site operating costs such as mining, processing, administration, royalties and production taxes, but are exclusive of amortization, reclamation, capital and exploration costs. These costs are then divided by ounces produced to arrive at the cash operating costs per ounce of production. The measure, along with production, is considered to be a key indicator of a corporation's ability to generate operating earnings and cash flow from its mining operations. This data is furnished to provide additional information and is a non-GAAP measure. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and is not necessarily indicative of operating costs presented under GAAP. Desert Sun uses the financial measure "adjusted net earnings/(loss)" to supplement its consolidated financial statements. The presentation of adjusted measures are not meant to be a substitute for net earnings/(loss) presented in accordance with GAAP, but rather should be evaluated in conjunction with such GAAP measures. Adjusted net earnings/(loss) is calculated as net earnings/(loss) excluding (a) non-cash stock-based compensation expense; (b) foreign exchange gain/(loss); (c) non cash write-down of accounts receivable and (d) future income tax expense (as applicable). The term "adjusted net earnings/(loss)" does not have a standardized meaning prescribed by GAAP and therefore Desert Sun's definitions are unlikely to be comparable to similar measures presented by other companies. Desert Sun's management believes that the presentation of adjusted net earnings/(loss) provides useful information to investors because it excludes non-cash charges and is a better indication of Desert Sun's profitability from operations. The items excluded from the computation of adjusted net earnings/(loss), which are otherwise included in the determination of net earnings/(loss) prepared in accordance with GAAP, are items that the Corporation does not consider to be meaningful in evaluating its past financial performance or its future prospects and may hinder any comparison of its period to period profitability.

RECENT DEVELOPMENTS SUMMARY OF 2005 In the year ended December 31, 2005, Desert Sun achieved significant milestones relating to the Jacobina Mine and associated exploration program: 1. The Jacobina Mine has been reactivated and at full production is expected to produce 100,000 ounces of gold per annum. The first gold was poured at the reactivated Jacobina Mine in March 2005, commercial production was declared effective July 1, 2005 and the mine operated at 85% of capacity in the fourth quarter ended December 31, 2005. 2. The Jacobina Mine produced a total of 11,935 ounces from the first gold pour at the end of March 2005 to June 30, 2005. Of this total, 9,889 ounces were sold by June 30, 2005 at an average net sale price of US$427 per ounce and the proceeds of US$4.2 million, less the attributable costs of production, were credited against mine development costs. During the second quarter of 2005, the mill processed 210,400 tonnes with an average grade of 2.16g Au/t resulting in the production of 11,873 ounces of gold. 3. In the three months ended December 31, 2005 the mill processed 327,329 tonnes with an average grade of 2.23 g Au/t resulting in production of 22,550 ounces of gold (compared with 300,505 tonnes with an average grade of 2.03 g Au/t resulting in the production of 18,683 ounces of gold during the first quarter of commercial production ended September 30, 2005). The metallurgical recovery rate was 96.0%. Sales of gold in the third quarter totaled 20,399 ounces at an average net sale price of US$484 per ounce. Sales of silver generated a by-product credit of approximately US$6,000. 4. As of December 31, 2005 proven and probable mineral reserves in the Jacobina Mine (Joao Belo Zone) are 13,220,000 tonnes grading 2.15 g Au/t containing 913,100 ounces of gold. Total Proven and Probable mineral reserves in all zones are 21,580,000 tonnes grading 2.18 g Au/t containing 1,510,000 ounces. This is an increase of 310,000 ounces from the August 2005 reserve estimate. 59 Desert Sun is using this new reserve estimate in the Jacobina Mine development plan, which increases mine life by over three years. A pre-feasibility study is currently in progress for the Canavieiras Mine, which has the potential to further increase reserves. The new estimate at the Joao Belo Zone contains a contribution from the newly discovered FW (Footwall) Reef in the main ore zone. The mineral reserves, set out in the table of below, were estimated using a gold price of US$400 per ounce and a block cutoff grade of 1.41 g Au/t. Dilution and mining recovery rates appropriate for each zone were applied following established practices at the mine.

[NTD: Need QPs identified] 5. An internal review and evaluation of Desert Sun's development projects was completed in January 2005, with Morro do Vento identified as the next project to be developed. A pre-feasibility study of Morro do Vento, which is located 1.5 km from the Jacobina processing plant, was completed in August 2005 and confirmed the economic viability of developing the Morro do Vento Mine. Micon International Limited of Toronto completed the review of mineral resources; AMEC Americas Limited of Vancouver completed a review of the mill expansion and Devpro Mining Inc. of Sudbury, in conjunction with Desert Sun staff, completed the mine plan and mineral reserve estimate. All licences and permits necessary to initiate work at Morro do Vento have been received from the Brazilian environmental review agency, Centro de Recursos Ambientais (CRA). 6. During 2005, Desert Sun continued to make solid progress with its US$5 million exploration program within the Bahia Gold Belt and completed 25,676 metres of NQ diamond drilling in 130 holes, testing three major target areas: the Canavieiras and Morro do Vento Extension targets in the Jacobina Mine area, and the northern Bahia Gold Belt target area, 50 km north of the town of Jacobina. 60 JACOBINA MINE The gold mineralization of the Jacobina Mine is hosted almost entirely within quartz pebble conglomerates of the Serra do Corrego Formation, the lowermost sequence of the Proterozoic-age Jacobina Group. This Formation is typically 500 metres thick, but locally achieves thicknesses of up to one kilometre. Overall, the property covers 155 km of strike length along the trend of the Jacobina Group. Within the property, the Serra do Corrego Formation is exposed for 75 km. Despite the extensive exposure of the mine sequence most of the exploration and all of the non-artisanal mining activities have been concentrated along a ten-kilometre long central zone. The host rocks to the Jacobina gold mineralization are highly sorted and rounded quartz pebble conglomerate reefs of the Serra de Corrego Formation. Gold occurs as fine grains 20 to 50 microns in size predominantly within well packed conglomeratic layers in which medium to larger-sized quartz pebbles are present. The gold occurs within the matrix and often in association with pyrite and fuchsite. However, these accessory minerals also occur in the absence of gold. Gold-rich reefs show a characteristic greenish aspect because of the presence of the chromium-rich muscovite, fuchsite. Intra-reef quartzites typically contain low gold grades (<0.70 g/t Au). The gold-bearing reefs range in size from 1.5 to 25 m wide and can be followed along strike for hundreds of metres, and in some cases for kilometres. Some contacts between reefs and the later crosscutting mafic and ultramafic intrusives are enriched in gold. Reactivation of the Jacobina Mine started in earnest in April 2004. By May 2004, the underground mine was de-watered, by June 2004 the antiquated rail haulage system was removed, the drifts enlarged to accommodate mechanized equipment and new ramp development started, and in July 2004 ore development commenced. A complete fleet of new equipment was purchased from Atlas Copco and Volvo, which included 15-tonne LHDs (Load Haul Dump), 33-tonne haulage trucks, electric hydraulic 2-boom jumbos, and electric hydraulic ITH (in-the-hole) production drills. New ventilation, compressed air, and electrical systems were installed. Mine offices, heavy equipment mechanical shops, warehouses, staff facilities and a haulage road were completed by October 2004. The plant has been completely refurbished and modernized, with four additional leach tanks installed to increase leach time and gold recovery from the historical 92% to 96.5%. A new regeneration kiln has been installed and the CIP (carbon-in-pulp) circuit has been upgraded with a 100% increase in the screen capacity. A new crushing plant has been constructed with a throughput capacity of 386 tonnes-per-hour. The production plant has been fully automated with Siemens technology and is now operating with 40% less manpower. The capital project, including development of the Jacobina Mine, refurbishment of the mill facilities and the purchase of all machinery, equipment and vehicles, cost approximately US$37 million. The original 2003 SNC Lavalin Feasibility Study projected costs of US$34 million. Lower development costs were offset by pre-operational revenue beginning later than expected as a result of delays in the delivery of the long-hole drills. Desert Sun poured the first gold bar at the Jacobina Mine in March 2005 and declared commercial production effective July 1, 2005. The mine produced at 75% of operating capacity during the third quarter and at 85% of operating capacity in the fourth quarter as part of the planned ramp-up to full production. By the end of December 2005, the plant was operating consistently at its design capacity of 4,200 tonnes per day. Ore mined in the third quarter ended September 30, 2005 was 340,913 tonnes and ore milled was 300,505 tonnes at an average grade of 2.03 g Au/t. In the fourth quarter ended December 31, 2005, 380,304 tonnes of ore was mined and 327,329 tonnes of ore was milled. Gold production in the fourth quarter was 22,550 ounces at an average total cash cost of US$278 per ounce, compared with 18,683 ounces at an average total cash cost of US$292 per ounce in the third quarter. The average recovery rate at the mill was 95.7%, with a high of 96.5% reached in the month of November 2005. Total production for 2005 was 53,168 ounces, including production of 11,935 ounces in the preproduction phase. Average head grade at full production is projected to be 2.27g Au/t for 2006 with an average recovery rate expected at the plant of 96.5%. The production forecast is based on milling 4,200 tonnes per day. In August 2005, Desert Sun issued the results of a positive pre-feasibility study prepared by Devpro Mining in association with Micon International and AMEC Americas on the Morro do Vento target area located 1.5 kilometers north 61 of the processing plant. Desert Sun expects that the Morro do Vento mine will be the second production area at Jacobina and that it will add an additional 50,000 ounces per year bringing overall production to 150,000 ounces per year. The mining method and equipment will be similar to that currently used at the Jacobina Mine operations. AMEC Americas has been retained to carry out a basic engineering for the plant expansion. Desert Sun has started work at Morro do Vento, reaching the ore on the 720 Level at the end of December 2005. The first items of mining equipment have arrived on site and Desert Sun plans to develop the mine reaching full production capacity by the end of 2006. A strong mine development team has been assembled, which will oversee all work on the project. EXPLORATION Desert Sun initiated exploration at the Jacobina project in the fall of 2002. This program was substantially expanded in September 2003 and has continued at the rate of 25,000 metres of drilling per year since that time. The original property holdings, which extended approximately 62 kilometres along strike, have been expanded considerably so that the current property covers a strike length of 155 kilometres. The term "Bahia Gold Belt" was coined by Desert Sun to describe the overall gold mineralized belt of Proterozoic sediments. In the last three years, exploration has outlined five development projects (Joao Belo extension, Serra do Corrego, Morro do Vento, Morro do Vento Extension and Canavieiras) as well as outlined a promising target at Pindobacu, located 50 kilometres north of the town of Jacobina. Measured and indicated mineral resources for all zones at Jacobina now total 27,900,000 tonnes grading 2.57g Au/t containing 2,311,000 ounces of gold. This is a significant increase of 261,000 ounces of gold compared to the December 2004 measured and indicated resource of 24,800,000 tonnes grading 2.53g Au/t containing 2,050,000 ounces of gold. Since the August 2003 resource estimate that formed the basis for the SNC-Lavalin feasibility study, exploration and development work by Desert Sun has increased measured and indicated mineral resources by 949,000 ounces of gold at an average discovery cost of approximately US$10 per ounce. At the Jacobina Mine, drilling and development has outlined sufficient new measured and indicated resources to replace 2005 production. Additionally, inferred mineral resources in all zones now total 33,600,000 tonnes grading 2.80g Au/t, containing 3,029,000 ounces of gold. This is a substantial addition of 1,129,000 ounces of gold compared to the December 2004 inferred mineral resource of 22,200,000 tonnes grading 2.61g Au/t, containing 1,900,000 ounces of gold. This increase reflects major additions at the Jacobina Mine (Joao Belo zone) where inferred mineral resources now total 14,430,000 tonnes grading 2.66g Au/t containing 1,235,000 ounces of gold compared to the December 2004 inferred resource of 5,300,000 grading 2.33g Au/t containing 390,000 ounces of gold.

Mineral resources include the above mineral reserves. 2005 EXPLORATION PROGRAM In 2005, the exploration program continued at a high level of activity with a total of 25,676 metres of NQ diamond drilling completed in 130 holes. The prime target areas drilled were Canavieiras and Morro do Vento Extension in the Jacobina Mine area and at Pindobacu in the northern Bahia Gold Belt. Geological mapping, sampling, soil and rock geochemical sampling and geophysical (induced polarization) surveys were continued over much of the property, especially in the northern Bahia Gold Belt in the Pindobacu-Fumaca area. JACOBINA MINE AREA A total of 17,130 metres in 82 holes were drilled in targets in the Jacobina Mine area, excluding the Jacobina Mine (Joao Belo Zone) with the bulk of meterage drilled at Canavieiras and Morro do Vento Extension.

In addition to the above diamond drilling, at the Jacobina Mine (Joao Belo zone) two holes totalling 1,613 metres were completed by the mine in a deep drilling program to test the downdip and along strike extension of the main (LMPC reef) ore zone. Definition drilling and development work continued to expand the geological knowledge of the deposit and outlined a new conglomerate reef in the footwall of the ore zone. BAHIA GOLD BELT (EXCLUDING JACOBINA MINE AREA) Desert Sun holds property in the Bahia Gold Belt totaling 141,580 hectares and essentially controls the entire Bahia Gold Belt. Desert Sun carried out a program of regional and detailed geological mapping, prospecting, rock and soil geochemical sampling that allowed the classification of the primary types of gold occurrences and defined four major target areas across the belt outside of the Jacobina mine area. These target areas are, from north to south: o Gold-bearing quartz veins, stockworks and extensive silicified zones in a thick package of fuchsite-bearing, locally oxidized (after pyrite) quartzites and metaconglomerates in the Pindobacu-Fumaca area which may be the northern and separate extension of the Serra do Corrego Formation. Ultramafic dikes and sills emplaced in these sediments also host gold-bearing pyritic quartz veins. This target zone extends along strike for at least 18 kilometres north from Pindobacu. Gold-bearing shear zones related to the Pindobacu West Fault, which marks the contact between the Jacobina Group and the Mundo Novo Greenstone Belt, have also been identified within greenstone rocks in the Pindobacu-Fumaca area. These zones are characterized by strong silification and quartz veining typically with pyrite. o Targets along the Serra do Guardanapo hill, which extends for 23 kilometres along strike starting about 25 kilometres north-northeast of Jacobina. Gold mineralization in this target occurs in steeply dipping quartz veins and associated hydrothermal alteration (silicification, sericitization, chloritization and pyritization) in fine-grained quartzites and meta-pelites (andalusite schists) of the Serra da Paciencia Formation; o The Maravilha Fault zone, the south end of which is located 4 kilometres east of Jacobina at the Rio Coxo garimpo and that extends for 60 kilometres along strike northwards from there. A large number of gold occurrences are associated with this structure in shallow west dipping shear zones in Rio do Ouro Formation quartzites; and o Gold-bearing quartz pebble conglomerate of the northern extension of the Serra do Corrego Formation that extends for 45 kilometres along strike, north from the town of Jacobina. This formation hosts the mineral resources and mineral reserves in the Jacobina mine area to the south. In addition to the work cited above, Fugro-LASA-Geomag was contracted by Desert Sun in both 2004 and 2005 to complete induced polarization (IP) surveys over a number of targets identified in these major areas. Results of this survey, along with soil and rock chip sampling results and detailed geological mapping were used to outline drill targets. An initial drilling program totaling 2,000 metres was completed in late 2004 to test principally the Pindobacu-Fumaca area and this program was expanded to 8,546 metres in 2005. The total number of assay samples in the database is 12,823. PINDOBACU At Pindobacu there are a number of active garimpos (free miner workings) that extend along a strike length of 1.2 kilometres. Gold occurs as fine to locally coarse-grained native gold or associated with pyrite (or its weathered product, goethite) with tourmaline and fuchsite in quartz vein stockworks along low-angle thrust faults, high-angle reverse faults and fractures. Geological mapping, IP surveys and rock/soil geochemical surveys by DSM indicate that the hydrothermal alteration zone is much more extensive than indicated by the previous work. The zone has been traced for at least 3.2 kilometres along strike at Pindobacu and it likely extends a further 15 kilometres along 64 strike to the north through Fumaca. The alteration zone is up to 100 metres wide with the most intense portion characterized by intense silicification and quartz-tourmaline veining. A total of 36 holes totaling 5,942 metres were completed in 2005 to test the Pindobacu target area. These holes tested the zone over strike length of 1,200 metres. The latter series of holes focused on testing the core area that extends at least 700 metres along strike at a deeper level (100 to 150 metres) than the original series (50 to 80 metres). In addition to geological information from detailed mapping and drilling, locations of holes were optimized using results from the recently completed induced polarization geophysical survey that has been analyzed by John Buckle, P.Geo., consulting geophysicist. Highlights from drilling at Pindobacu are: o 5.46 g Au/t over a true width of 21.9 metres, including higher grade portions grading 12.27 g Au/t over a true width of 4.7 metres and 10.22 g Au/t over 5.5 metres true width. o 1.46 g Au/t over a true width of 24.4 metres. o 7.20 g Au/t over a true width of 2.0 metres. o 4.40 g Au/t over a true width of 3.4 metres. o 2.61 g Au/t over a true width of 1.8 metres. o 23.63 (13.51 with highs cut to 30 g/t) over a true width of 2.5 metres. o 3.11g Au/t over a true width of 8.0 metres. o 3.02 g Au/t over a true width of 5.1 metres. In addition, assay results for chip sampling in a shaft in the Pindobacu "garimpo" returned 3.27 g Au/t over 14.1 metres in a vertical section including 6.85 g Au/t over 5.0 metres. The deeper series of holes has confirmed that the strong alteration zone extends downdip to at least 150 metres. The most intense portion of the alteration is widening with depth from about 10 metres in the shallower holes to 20 metres in the deeper holes. Overall there is also more consistency in gold grades in the deeper holes, although the centre of the hydrothermal system as yet to be intersected. Based on drilling and detailed mapping at the Pindobacu, Entry Point and Fumaca targets, which cover 18 kilometres of strike length, a new model has been developed for the structural evolution and deposition of gold mineralization. Deformation is much stronger than previously recognized prior to drilling; gold mineralization occurs within fractured, faulted and brecciated quartzites in the hinge area of a major east dipping overturned anticline fold structure where the quartzites are capped by less permeable metavolcanic and metasedimentary rocks of the Archean Mundo Novo Formation. This folding occurred during a major tectonic event where rocks of the Mundo Novo Greenstone Belt were thrust westerly over quartzites and local conglomerates of the Jacobina Group which are equivalent in age to the quartzites and conglomerates of the Serra do Corrego Formation in the Jacobina mine area. The mineralogy and geochemistry of this system is remarkably similar to the gold mineralization in the quartz pebble conglomerates in the Jacobina mine area to the south. The regional Pindobacu Fault system which forms the eastern boundary of the Jacobina Basin is most likely a major focus of hydrothermal alteration and mineralization. It is possible that there could be a series of hydrothermal centres with significant gold mineralization along this extensive structure. FUMACA At Fumaca, located 10 kilometres north of Pindobacu, gold mineralization occurs in strongly silicified quartzites and minor metaconglomerates of the Jacobina Group in the western part of the area that are in fault contact with reddish clastic, chemical and pelitic metasediments and local pillowed basalt of the Archean Mundo Novo Group to the east. 65 Soil geochemical sampling by the Company has identified several anomalies in the area with a collective strike length parallel to the main structural trend of 1.3 kilometres. The induced polarization geophysical survey by Fugro-LASA-Geomag has outlined a linear zone of coincident chargeability and resistivity anomalies that extends over a strike length of 2 kilometres, a width of approximately 300 metres and to an indicated depth extent of at least 200 metres. The strongest response is in a zone approximately 50 metres wide that is coincident with the Fumaca garimpo. Sampling from the garimpo by Desert Sun returned 7.36 g Au/t over 4.5 metres including a very high grade bluish. Nine holes, totaling 1,575 metres have been completed to test several targets outlined by geological mapping/sampling, soil geochemical surveys and induced polarization surveys. Highlights included: o 0.72 g Au/t over a true width of 10.1 metres including a higher grade portion grading 1.95 g Au/t over 2.2 metres. o 0.86 g Au/t over a true width of 1.0 metre. o 1.37 g Au/t over 3.6 metres including a 1 metre interval grading 3.37 g Au/t. o 5.38 g Au/t over 1.4 metres true width. o 1.53 g Au/t over a true width of 1.4 metres. ENTRY POINT Dr. Paul Karpeta, an expert on Precambrian quartz pebble conglomerate-hosted gold deposits with extensive experience working on deposits in Witwatersrand, South Africa and Tarkwa, Ghana, was retained by Desert Sun in 2005 to carry out a study of the Jacobina basin in an attempt to identify additional entry points outside of the Jacobina Mine area. Entry points are the areas in a basin where major streams carry and deposit sediments into the basin and are typically marked by the thickest conglomerates with the largest pebbles. This work, which was done in close collaboration with Company personnel, identified a significant area of Jacobina Group sediments with quartz pebble conglomerate layers that are exposed in a large tectonic window across an area 5,000 metres long by 900 metres wide about 5 kilometres northwest of Pindobacu. Gold garimpos (free miner workings) occur around this "window" near the contact with volcanic rocks of the Mundo Novo Formation, which have been thrust over the conglomerates and then subsequently eroded. In contrast to the mine area, the sedimentary rocks here are relatively flat lying hence only a small portion of the overall stratigraphic sequence is actually exposed. Dr. Karpeta concluded that the Jacobina Basin has been subdivided by cross structures into major compartments, which controlled sedimentation in those compartments. One such cross structure is marked by a prominent lineament about 6 kilometres south of the town of Pindobacu, north of which is the Pindobacu Compartment and to the south is the Jacobina Compartment. Each of these compartments will have a different stratigraphy and hence different auriferous conglomerates. Typically, within each compartment there is usually one entry point marked by the thickest conglomerates with the biggest pebbles and typically are the richest conglomerates. Dr. Karpeta concluded that these entry points occur around the Jacobina Mine Area in the Jacobina Compartment and potentially around Mina Velha, 5 kilometres northwest of Pindobacu, in the Pindobacu Compartment. Induced polarization (IP) surveys completed by Fugro-LASA-Geomag in this newly recognized area outlined targets that appear to be strongly silicified rocks with disseminated sulphides. A limited diamond drilling program was completed in 2005 to complete a section of holes across this area and to test several of the IP survey anomalies. The Entry Point Target is located 5.5 kilometres north form the town of Pindobacu, midway between the Pindobacu (5 kilometres to the south) and Fumaca (6 kilometres to the north) targets. Six reconnaissance drill holes totaling 1,608 metres were completed in 2005 to test the stratigraphy of the area and to test for the potential to host gold mineralization. Two holes drilled to lengths of 440 metres and 488 metres, respectively, intersected a package of interbedded pebbly quartzite and quartzite with several beds of conglomerates with small to medium-sized pebbles of quartz. 66 Widespread hydrothermal alteration including fuchsite and silicification was present in both holes with local disseminated pyrite. Anomalous gold values typically ranging from 100 to 300 ppb were returned with a best result of 0.57 g Au/t over 0.59 metres. Collared 900 metres to the south, another hole tested an area where surface channel sampling had returned 1.0 g Au/t over a strike length of 14.0 metres in quartz pebble conglomerate. This hole intersected a medium pebble conglomerate which returned 1.55g Au/t over 5.4 metres. The drill holes in the Entry Point area have confirmed the presence of quartz pebble conglomerates with hydrothermal alteration, which are the first significant quartz pebble conglomerate-hosted gold found outside the Jacobina mine area. The thin layers of conglomerate intersected in the holes indicate that the holes were likely drilled on the edge of the entry point system. Further work will focus on locating the centre of the entry point where the channels with the coarsest conglomerates that are the prime target for gold mineralization will likely be. Results of the IP surveys will also assist in locating this target. MORRO DO VENTO The Morro do Vento target area is located about 1.5 kilometres from the processing plant and approximately 9 kilometres from the town of Jacobina. The Intermediate reef package here is consistently about 60 to 70 metres wide and extends along the full 2 kilometre strike length with extensive garimpos (free miners workings). This target was identified as a result of drilling in the adjacent Morro do Vento Extension (Cuscuz) area in 2002 and compilation of historical drilling data. The results of an induced polarization survey completed in 2003 at Morro do Vento indicated that the mineralized horizon likely extended over 400 metres down dip into the valley. The former Itapicuru mine had workings in the Morro do Vento and Morro do Vento Extension (Cuscuz) areas, although most of the previous production came from the Basal and Main Reefs. Past production from the Intermediate Reefs at Morro do Vento was 413,974 tonnes grading 3.87 g Au/t from one conglomerate layer 1.9 metres thick at the north end of the area. The Intermediate Reefs are stratigraphically 350 metres and 300 metres, respectively, above the Basal and Main Reefs. The package is exposed on the east flank of the Morro do Vento hill. The slope of the hill is a dip slope averaging about 55o E dip. The reefs extend from the top of the hill, at elevation 1,000 metres, to the valley, at elevation 630 metres, where they are truncated by a steeply dipping mafic intrusive. There are numerous garimpos along the entire strike. At Morro do Vento, the Intermediate Reef package consists of quartz pebble conglomerate layers interbedded with quartzite that averages about 40 to 70 metres in width and extends along strike for 2 kilometres. Conglomerates comprise approximately 25% to 40% of the package and have a distribution typical of a braided stream environment in contrast to the likely alluvial fan environment that the conglomerates in the main ore zone at the Jacobina mine were deposited in. In 2003 and 2004, Desert Sun drilled a total of 14,000 metres in 80 drill holes and outlined a new indicated resource of 5,016,000 tonnes grading 2.08 g Au/t containing 335,000 ounces of gold above the 800 level. The majority of mineral resources are hosted within the LU and MU reefs. An internal mining study by Desert Sun in the first half of 2005 identified Morro do Vento as the next likely mine in the Jacobina Mine area and concluded that development was best done from underground. A positive pre-feasibility study was subsequently completed on Morro do Vento in August 2005 by Devpro Mining and slashing / development of the 720 level adit access began in late 2005. A power line directly to the Morro do Vento site is currently under construction and the mining equipment has been ordered. A strong mine development team has been assembled that will oversee all work on the project. Highlights of the pre-feasibility study: o Mineral reserves estimated to be 3,586,000 tonnes at 2.09 g Au/t containing 241,000 ounces of gold o Morro do Vento Mine to produce 50,000 ounces per year at a cash cost of US$240 per ounce, beginning in 2006 67 o Capital cost (net of pre-production cash flow) is estimated at US$17.2 million o Recovered gold including pre-production is estimated at 229,000 ounces o 20% Internal Rate of Return with a Net Present Value of US$8.4 million at a 5% discount rate o 5.5 year mine life with excellent potential to outline additional mineral reserves The total indicated mineral resources at Morro do Vento are estimated to be 5,790,000 tonnes grading 2.18 g Au/t, containing 406,000 ounces of gold using a conventional polygonal method. Inferred mineral resources are estimated to be 2,470,000 tonnes grading 2.42 g Au/t, containing 192,000 ounces of gold. The pre-feasibility study considered the indicated mineral resources above the 800 level only, which total 5,016,000 tonnes grading 2.08 g Au/t, containing 335,000 ounces of gold. Probable mineral reserves at US$350 per ounce gold price are estimated to be 3,586,000 tonnes at 2.09 g Au/t containing 241,000 ounces of gold. There is excellent potential to both upgrade and expand mineral resources below the 800 level. Mining will be by conventional long hole open stoping using top hammer long hole drills, 6.2 m(3) LHDs, and 33-tonne low profile haulage trucks. Geotechnical aspects of the mine design have been reviewed by MLF Geotecnica Mechanica de Rochas Ltda ("MLF") of Nova Lima, Brazil, who indicated that ground conditions are expected to be good and there should be no problems with ground stability with the current mine design. AMEC Americas Inc. of Vancouver, B.C. ("AMEC") considers that the Morro do Vento mineralization will behave in a metallurgically similar way to the Joao Belo ore currently being processed and that treatment of any ratio of these ores will not significantly impact metallurgical plant performance. Access will be via the 720 Level adit, at the north end of the Morro do Vento area, which is approximately 200 metres from the crusher and accessed via the existing Jacobina Mine (Joao Belo Zone) haul road. Existing mine infrastructure, including mechanical shops, warehousing and staff facilities will be utilized to accommodate the Morro do Vento operation. The results of the study have identified a number of modifications to the milling facilities to increase the throughput from 4,200 tonnes per day to 6,500 tonnes per day: o Installation of a new secondary crushing circuit to produce a finer crushed product prior to grinding. o Replacement of the grinding cyclones and corresponding feed pumps with higher capacity units in order to handle the increased throughput. o Installation of a new thickener that would function in parallel with the existing circuit. The current sand/slime system would be abandoned. o In the leaching area, an increase in the number of mechanically agitated leach tanks to provide the optimal leach residence time is required. A new leach feed vibrating screen, leach feed sampler and leach transfer pumps are also required to handle the increased capacity. o Installation of a new CIP tails vibrating screen and sampler to handle the increased tailings capacity. o Replacement of the tailings disposal pipeline with a new larger diameter pipeline to handle the increased capacity. o Installation of new process water distribution pumps to handle the increased water requirements. o Primary crushing, carbon in pulp, carbon stripping and reactivation, reagent handling and refining circuits were deemed to have sufficient capacity to accommodate the increased capacity. 68 All environmental licenses required for the Morro do Vento operation have been received. The existing freshwater supply and discharge water systems will be utilized, as well as the storm water drainage system. Closure costs associated with the Morro do Vento mine are considered to be included with the Jacobina Mine complex closure plan. Total capital cost is estimated to be US$31.2 million for the project. Gold produced from capital development in ore, amounts to US$14 million making the total new capital requirements for the project of US$17.2 million. The underground mine sustaining capital has been estimated to be US$5.8 million, to primarily be incurred in the years 2007 and 2008 for equipment rebuilds and ongoing mine development. Devpro Mining Inc. (Devpro) was contracted by Desert Sun to co-ordinate the preparation of this pre-feasibility level report. Mr. Terrence Hennessey, P.Geo. of Micon International Limited (Micon) reviewed the geological aspects of the study and the mineral resource estimates. Mr. Rick Adams, of Devpro reviewed the mining methods and layouts, preparation of the mineral reserve estimates, and mine capital and operating cost estimates. Mr. Joe Milbourne, QP of AMEC prepared a study of the milling and metallurgical aspects of the Morro do Vento deposit mineralization, and MLF reviewed the geo-mechanical aspects of the project with respect to ground stability. The individuals cited above are all independent qualified persons as defined under National Instrument 43-101. MORRO DO VENTO EXTENSION The Morro do Vento Extension target is located immediately north of the processing plant in the Jacobina Mine area. The former Itapicuru mine had workings in both the Morro do Vento and Morro do Vento Extension (Cuscuz) areas, although most of the previous production came from the Basal and Main Reefs. These reefs are stratigraphically 350 metres and 300 metres, respectively. Previous mining and exploration focused on the high-grade zones in these reefs, which were mined in stopes that were typically 2 to 2.5 metres wide, although the full width of the mineralized conglomerates is typically 10 to 15 metres wide. Past production from the Basal and Main Reefs in both the Morro do Vento and Morro do Vento Extension areas, as reported by Anglo American, totalled 2,036,634 tonnes at a recovered grade of 4.14 g Au/tonne producing 271,046 ounces of gold. At the Morro do Vento Extension area 24 drill holes totaling 8,511 metres were completed in 2005. This drilling focused on testing the downdip continuation of the Basal and Main reefs in the Morro do Vento Extension area, as well as the exploring the southern continuation of the Basal and Main reefs into the Morro do Vento area that have a potential strike length of at least 600 metres. The Main Reef, which is stratigraphically about 50 metres above the Basal Reef, is a major target that was intersected in the new drill holes and is the northern extension of the same reef in the Morro do Vento area that was previously mined. A limited underground drilling program was also carried out in the Morro do Vento Extension area from the 630-metre level to test the potential for the Main Reef at shallower levels. Surface drilling is continuing to complete drilling needed to outline additional indicated mineral resources and to continue to test the 600 metre long target area between the Morro do Vento Extension and the north end of Morro do Vento. Highlights of drilling include: o 3.25 g Au/t over a true width of 17.8 metres and 3.71 g Au/t over 5.3 metres true width, respectively, in the Main Reef. o 3.25g Au/t over 17.8 metres true width in Main Reef. o 3.71g Au/t over 5.3 metres true width in Main Reef. o 3.25 g Au/t over a true width of 17.8 metres in the Basal Reef. o 3.21g Au/t over 7.4 metres true width in Main Reef and 2.88g Au/t over 8.8 metres true width in Basal Reef. o 3.84g Au/t over a true width of 7.1 metres in 14.4 metres (true width) grading 2.54g Au/t in Basal Reef. 69 o 5.94g Au/t over 3.8 metres true width in Main Reef. o 3.51g Au/t over 4.9 metres true width in Main Reef. o 3.66g Au/t over a true width of 4.8 metres in 14.5 metres true width grading 1.99g Au/t in Basal Reef. (underground hole) o 2.26 g Au/t over 7.6 metres true width in Basal Reef. o 5.81g Au/t over 2.3 metres true width in the Main Reef and 4.47g Au/t over 1.8 metres true width in the Basal Reef. o 3.23 g Au/t over 3.5 metres true width in Basal Reef. CANAVIEIRAS The former Canavieiras mine is located 3 kilometres north of the processing plant, in a block bounded by faults that is approximately 1.2 kilometres long and 400 metres wide. In contrast to the main conglomerate trend, Canavieiras is characterized by moderate folding. The high grades at Canavieiras, compared to the other zones in the Jacobina mine area, appears to results from a later stage of hydrothermal activity characterized by hematite-gold that is related to sinistral shearing. Past production, primarily from the Piritoso and Liberino reefs, in the Canavieiras Mine is reported by Anglo American to total 458,247 tonnes at a grade of 8.65 g Au/t. A hole drilled in 1997 by William Resources intersected 7.0 g Au/t over a true width of 24.0 metres in the MU reef below the old workings, but no further follow up drilling was done at that time. Work by Desert Sun has focused on evaluating the full stratigraphic package hosting the favourable conglomerate beds, which is estimated to be over 300 metres thick. During 2005, the workings including drifts, raises, stope limits, old drill holes and major faults in the old mine were re-surveyed to eliminate survey errors that were found during data compilation and modeling. A new cross-cut, 92 metres long was also driven from an old stope in the southeastern part of the old workings to provide access to more effectively drill potential extensions to the east and south. A total of 56 holes totalling 8,287 metres were completed in 2005. The bulk of the program focussed on upgrading existing inferred mineral resources to the indicated category and exploring the potential extensions of the mineralized stratigraphy to the south and east. Several step out holes were completed up to 300 metres to the south of the old mine to explore the potential of the stratigraphy there that indicated a major extension to the known mineralized zone. Major targets at Canavieiras include: o MU and LU reefs about 50 metres below the Canavieiras mine workings. o Potential high grade extension in the Piritoso-Liberino reefs adjacent to the old stope in the southern end of the mine. o Hollandez-Maneira reefs above the old mine workings. o Southern continuation of favourable mineralized stratigraphy based on geological compilation work and induced polarization surveys. TARGET REEFS BELOW OLD WORKINGS (MU AND LU REEFS) The MU (Middle Unit) and LU (Lower Unit) reefs are about 50 to 100 metres below the old workings. The strike length of the MU and LU reefs is now at least 600 metres with the zones open along strike to the south. Thickness of the MU reef ranges from 8.8 metres to 27.5 metres with an average of 21.9 metres and that of the LU reef, from 0.9 metres to 22.3 metres with an average of 5.2 metres. Stratigraphically the two reefs are very close in the southern holes, but become 70 progressively more separated to the north by an interbedded quartzite unit. In the northernmost hole to intersect MU/LU, the quartzite unit separating these reefs is about 12 metres thick. Drilling in 2005 intersected a number of very high grade intervals within the target reefs including: o 8.40 g Au/t (7.84 g Au/t with highs cut to 30 g Au/t) over 15.2 metres in the MU reef and the LU (Lower Unit) zone grading 9.29 g Au/t (7.75 g Au/t with highs cut to 30 g Au/t) over 6.4 metres. o 23.88 g Au/t (14.66 g Au/t cut) over 12.9 metres in the top of the MU reef and 11.02g Au/t (7.93 g Au/t cut) over 13.6 metres in the base of the MU reef and the LU reef. o 4.47g Au/t over a true width of 10.1 metres within a 32.9 metre (true width) section grading 2.05g Au/t. o 4.83g Au/t over 6.1 metres true width. o 3.52g Au/t over a true width of 7.4 metres. o 3.97 g Au/t (3.31 cut) over 15.4 metres true width in 31.5 metres grading 2.28 g Au/t (1.96 cut). o 2.49 g Au/t over a true width of 20.9 metres. o 4.26 g Au/t over a true width of 5.8 metres. o 5.23 g Au/t over a true width of 4.4 metres. o 3.28 g Au/t over a true width of 6.4 metres. There is a very clear southwesterly plunge to the mineralized trend. The high grade areas have significant visible gold and there is in general a strong association with hydrothermal hematite alteration. TARGET REEFS EXTENDING ZONES PREVIOUSLY MINED (PIRITOSO AND LIBERINO REEFS) The Piritoso and Liberino reefs were previously mined at Canavieiras over a strike length of about 600 meters and these were the richest reefs in the camp. Piritoso is a very pyritic medium sized quartz pebble conglomerate reef that is from 0.1 metres to 5.6 metres thick averaging about 2.6 metres thick. Average grade in the reef mined was 9.5 g Au/t. The Liberino reef is about 10 metres stratigraphically above the Piritoso reef with a thickness ranging from 0.1 metres to 3.2 metres with an average thickness of 1.2 metres. Pebble size in Liberino ranges from medium to large with less packing as compared to Piritoso. Average grade in the reef mined was 6.1 g Au/t. Highlights of drilling in 2005 in this target zone include: o 16.52g Au/t over 3.2 metres true width within 10.3 metres true width grading 3.90g Au/t. o 11.94g Au/t over 2.4 metres true width within 9.9 metres true width grading 4.07g Au/t. o 4.82g Au/t over a true width of 4.0 metres. o 6.61g Au/t over a true width of 2.2 metres. o 21.62g Au/t (19.49 highs cut to 30g/t) over 2.6 metres true width within 9.9 metres (true width section) grading 7.04g Au/t (6.49 g Au/t with highs cut to 30 g/t). o 15.28g Au/t over 4.0 metres true width in 17.8 metres true width grading 4.67g Au/t. o 18.12g Au/t over a true width of 2.3 metres. 71 o 17.57g Au/t (11.77 cut) over a true width of 1.4 metres. o 4.06g Au/t over a true width of 8.4 metres. HOLLANDEZ-MANEIRA REEFS The Hollandez Reef is typically 15 to 20 metres thick, although in places is up to 40 metres thick, with significant gold mineralization occurring in the lower part of the reef. The reef extends along a north-south strike for at least 1 kilometre of which 500 metres of this strike length would be readily accessible from existing mine workings in the Canavieiras Mine. The most significant intersection in this reef in the old mine area was drilled in 2004, that intersected 8.47 g Au/t over a core length of 13.02 metres (8.07g Au/t with highs cut to 30 g/t; true width 5 metres to 10 metres) in a strongly silicified zone near the base of the Hollandez reef adjacent a steeply dipping fault zone filled with a mafic dyke. Mineralization occurs as disseminated pyrite and very fine native gold in a "silica gel" that is most likely the product of hydrothermal alteration. A hole drilled in 2005 intersected 4.06g Au/t over 8.4 metres in the Piritoso and Liberino reefs. The mineralization in this hole also displays a classic hydrothermal silica texture with disseminated pyrite and very fine native gold. These results strongly suggest that there is a hydrothermal feeder system responsible for the high grade gold mineralization. This structure is likely steeply dipping with a southeasterly strike. Wherever this structure cuts the conglomerate stratigraphy, high grade gold mineralization is very likely to occur. The Maneira Reef, which is 30 metres stratigraphically above the Hollandez reef, comprises the upper sequence of conglomerates in the Serra do Corrego Formation. It is typically 70 metres thick dipping 55 degrees to the east, and comprises a very large quartz pebble conglomerate at the base which grades to a medium-sized quartz pebble conglomerate at the top. The conglomerates typically have a fuchsite-rich matrix, sometimes oxidized. Gold mineralization is presented at both the base and top. This reef was only tested in a few holes in the 2005 program, because it is the highest reef in the stratigraphy and is usually exposed above most surface drill sites and well above underground drill sites. STEP OUT HOLES SOUTH OF OLD MINE AREA (HOLLANDEZ, PIRITOSO, LIBERINO, MU AND LU REEFS) Historical diamond drilling indicated that gold mineralized conglomerates were present on strike to the south of the old mine area, however these holes did not test the full stratigraphic package and were drilled at less than favourable azimuths based on the new geological data generated by the drill program in the old mine area. Two step holes were completed in 2005 and both of these holes intersected high grade gold mineralization in the major reef targets (Hollandez, Piritoso-Liberino and MU and LU). Highlights from the two step-out holes are as follows. o 11.71g Au/t (10.09 g Au/t with highs cut to 30g Au/t) over a true width of 5.3 metres (MU reef); o 6.15g Au/t over 3.4 metre true width Lower Unit (LU) reef; and o 2.53g Au/t over a true width of 8.4 metres in a wider zone grading 2.01g Au/t over a 14.4 metres true width (Hollandez reef). o 3.94 g Au/t over a true width of 9.6 metres in a wider section grading 2.36 g Au/t over a true width of 31.4 metres (MU reef); and o 3.20 g Au/t over a true width of 5.9 metres (Liberino reef); 2.60 g Au/t over 5.3 metres and 37.45 ? over 0.3 metres true width (both Hollandez reef). In preparation for the 2006 drill program at Canavieiras, the old No. 6 adit located about 230 metres south of the south limit of the stoped area of the old mine was rehabilitated and services for drilling installed. Drilling from underground in the No. 6 adit will commence in January 2006. 72 JOAO BELO ZONE -- DEEP DRILLING PROGRAM A deep surface drilling program was initiated at the Jacobina Mine (Joao Belo Zone) to test the potential down dip extension of the ore zone to a depth of 600 metres and along strike to the south. A total of eight holes are planned totalling 6,700 metres, of which two holes totalling 1,613 metres were completed in 2005. The objective of this program is to significantly expand the inferred mineral resources. Knowledge of the location and extent of the inferred resources will enable more effective mine exploration and development planning. In November 2005, the Company announced the discovery of a new conglomerate reef -- the Foot Wall Reef (FW reef), located approximately 40 meters in the footwall of the ore zone that is currently being mined. The new reef was encountered during main access ramp development at the 555 meter level and the 530 meter level. Work has included development of two cross-cuts to fully expose the reef on the 530 and 555 meter levels, channel sampling and diamond drilling. The ongoing development program has exposed the FW reef to date over a continuous strike length of 180 meters and a step-out drilling program is underway. Significant channel sampling results of 4.25g Au/t over a true width of 9.05 metres and 3.38g Au/t over a true width of 8.40 metres were returned in the 530 and 555 level cross cuts, respectively. An underground drill hole intersected 5.2g Au/t over 0.6 metres true width within a broader zone of low grade mineralization (0.58g Au/t over an 8.3 metres true width) in the FW reef 200 metres north of the 530 level cross cut, suggesting a potential strike length of over 300 metres. The deep surface drill holes also tested the potential downdip and along strike extension of the new conglomerate reef, intersecting 2.64 g Au/t over a 4.3 metres true width. Geological work by Desert Sun and a recent review of the new zone by Dr. Paul Karpeta indicates that the FW Reef is probably a north-south oriented gravel channel fill, which likely lenses out laterally before it reaches the surface. The reef is typically a very coarse conglomerate with fracturing and widespread hematite alteration. There appears to be two stages of gold mineralization -- an earlier pyrite-gold stage that has been overprinted by a later hydrothermal hematite-gold stage related to cross-cutting fractures; the latter appears to be responsible for the elevated grades seen in several areas. SERRA DO CORREGO The Serra do Corrego target area, located 2 kilometres north of the processing plant, is a 900 metre long target zone. Two reefs known as MU and LU, which are equivalent to reefs of the same name in Morro do Vento to the south and Canavieiras to the north, are the principal targets. Extensive garimpos are found across the hillside following these conglomerates. The MU reef is best developed in the southern part of the target area and thins northward. In contrast, the LU reef continues across the majority of the hillside with characteristically deeply incised garimpos. Desert Sun has carried out resampling of available old core in the vicinity of the MU and LU Reefs, which suggests that there may, in places, be underestimation of grade in lower grade areas such as the quartzites between reefs. OTHER TARGETS SERRA DO CORREGO -- MANEIRA REEF The Maneira reef is exposed at surface on the east side of the Serra do Corrego hillside for a strike length of about 700 metres. Inferred mineral resources in two blocks total 1,252,000 tonnes grading 3.53 g Au/t. A hole drilled in 2003 returned 4 g Au/t over 10.0 metres true width. This target is planned to be drilled in the 2006 program. SERRA DO CORREGO -- LAGARTIXA/VIUVA This area is located on the west side of the Serra do Corrego hillside about 3 kilometres (Lagartixa) to 4.5 kilometres (Viuva) north of the processing plant. Geologically this is a complicated area with thrusting and repetition of stratigraphy. Lagartixa/Viuva appears to be potential extensions of the upper stratigraphy that hosts the gold-bearing conglomerates at Canavieiras. There is a 170 metres long garimpo in the Lagartixa portion of the target area. This target is planned to be drilled in the 2006 program. 73 SERRA DO CORREGO -- MARICOTA At Maricota, which is located beside the main mine highway and entrance to the road to Serra do Corrego, garimpos have been mining high grade gold along fault structures cutting the Basal Reef very close to the basement contact. The target area here has at least a 100 metre strike length, but may be more extensive. Two drill holes were completed in 2005 to test the potential of the Basal Reef here, but both holes returned no significant results. BOUGHT DEAL FINANCINGS On March 22, 2005, the Corporation completed a bought deal financing pursuant to which it raised $25 million through the issuance of 10,729,614 units at a price of $2.33 per unit. Each unit consisted of one Desert Sun Share and one-quarter of one Desert Sun Warrant. On December 15, 2005, Desert Sun completed a bought deal financing pursuant to which it raised $40 million through the issuance of 16,000,000 units at a price of $2.50 per unit. Each unit consisted of one Desert Sun Share and one-quarter of a Desert Sun Warrant. 74 CURRENCY PROTECTION AGREEMENT On March 3, 2005, Desert Sun entered into an agreement with BankBoston to purchase an average of 3 million Brazilian Real monthly in 2006 at a price of US$1 million. The amount hedged under this agreement represents approximately 75% of the projected 2006 Brazilian Real-denominated operating costs of the Jacobina Mine and the exchange rate under the agreement is in line with the exchange rate assumptions used in the Feasibility Report on the Jacobina Gold Project, Brazil prepared by SNC Lavalin Engineers and Constructors dated October 2003. CHANGES TO MANAGEMENT AND BOARD Mike Hoffman, P.Eng, was appointed the Vice President, Strategic Development of Desert Sun effective September 19, 2005. CHANGE OF YEAR END As of February 27, 2004, Desert Sun changed its financial year end from August 31 to December 31 to coincide with the year end of its subsidiary Jacobina Mineracao e Comercia Ltda. Under Brazilian law, Jacobina Mineracao e Comercio is required to have a year end of December 31. Desert Sun believed that it would be more cost efficient and in the best interests of Desert Sun and its shareholders for both companies to have the same financial year end. Desert Sun implemented this change by having a transition financial year of 16 months, the last day of which was December 31, 2004.

Equity compensation plans not 0 N/A N/A approved by security holders.... TOTAL............................. 9,127,663 1.43 841,593 REPORT ON EXECUTIVE COMPENSATION The compensation policy of Desert Sun is derived from the perspective of ownership. Executive officers expect to reap the majority of their income from the appreciation in value of the Desert Sun Shares they hold. Given that members of management are retained as consultants as opposed to employees, the compensation practices are flexible, entrepreneurial and geared to meeting the requirements of the individual and hence securing the best possible talent to run Desert Sun. Compensation of officers currently consists of a monthly retainer, stock options and discretionary bonuses. 81 Management compensation is kept below market rates for comparable positions and is sufficient to maintain an individual's cash flow. The amounts are determined on a discretionary basis after review by the Compensation Committee of the contribution of each executive officer of Desert Sun. Bonuses may be paid for significant and specific achievements that have a strategic impact on the fortunes of Desert Sun. Although they may be members of the Board of Directors, the executive officers do not individually make any decisions with respect to their respective salary or bonus. The three main components of the compensation of the Chief Executive Officer of Desert Sun are base salary, annual incentive and a long-term incentive based on participation in Desert Sun's share compensation plan. Competitive benefits and perquisites are also provided. The components of the Chief Executive Officer's compensation are the same as those that apply to the other senior executive officers of Desert Sun. These components are set forth in the consulting agreement between Mr. Humphrey and Desert Sun, which provides for a minimum base salary of 325,000. The Chairman of the Compensation Committee presents recommendations to the Board of Directors with respect to the Chief Executive Officer's compensation. In setting the Chief Executive Officer's salary and bonus, the Compensation Committee reviews salaries and bonuses paid to other senior officers of Desert Sun, salaries and bonuses paid to the other chief executive officers in the industry and the Chief Executive Officer's impact on the achievement of Desert Sun's objectives for the previous financial year. Submitted on behalf of the Compensation Committee: Kenneth Taylor -- Chairman Gerald McCarvill Nancy E. McInerney-Lacombe CORPORATE GOVERNANCE PRACTICES In June 2005, National Policy 58-201 Corporate Governance Guidelines (the "Governance Guidelines") and National Instrument 58-101 Disclosure of Corporate Governance Practices (the "Governance Disclosure Rule") were adopted by the securities regulatory authorities in Canada. The Governance Guidelines deal with matters such as the constitution and independence of corporate boards, their functions, the effectiveness and education of board members and other items dealing with sound corporate governance practices. The Governance Disclosure Rule requires that, if management of an issuer solicits proxies from its security holders for the purpose of electing directors, specified disclosure of its corporate governance practices must be included in its management information circular. Desert Sun and the Board of Directors recognize the importance of corporate governance to the effective management of Desert Sun and to the protection of its employees and shareholders. Desert Sun's approach to significant issues of corporate governance is designed with a view to ensuring that the business and affairs of Desert Sun are effectively managed so as to enhance shareholder value. The Board of Directors fulfills its mandate directly and through its committees at regularly scheduled meetings or as required. Frequency of meetings may be increased and the nature of the agenda items may be changed depending upon the state of Desert Sun's affairs and in light of opportunities or risks which Desert Sun faces. The directors are kept informed of Desert Sun's operations at these meetings as well as through reports and discussions with management on matters within their particular areas of expertise. Desert Sun's corporate governance practices have been and continue to be in compliance with applicable Canadian and United States requirements. Desert Sun continues to monitor developments in Canada and the United States with a view to further revising its governance policies and practices, as appropriate. The following is a description of Desert Sun's corporate governance practices which has been prepared by the Corporate Governance Committee of the Board of Directors and has been approved by the Board of Directors. 82 BOARD OF DIRECTORS INDEPENDENCE OF THE BOARD OF DIRECTORS Three out of the six members of the Board of Directors are independent within the meaning of the Governance Disclosure Rule and the Board of Directors and the independent members hold regularly scheduled meetings. The Corporate Governance Committee is chaired by Peter Bojtos and Nancy McInerney-Lacombe and Ken Taylor are also members. Each of the members of the Corporate Governance Committee is independent. Stan Bharti is a related director because he receives fees from Desert Sun as a special consultant and Chairman of the Board of Directors. Bruce Humphrey is a related director because of his position as President and Chief Executive Officer of Desert Sun. Gerald McCarvill is a related director because he receives fees from Desert Sun as a special consultant and Vice-Chairman of the Board of Directors. To facilitate the Board of Directors functioning independently of management, the following structures and processes are in place: o there are no members of management on the Board of Directors, other than the President and Chief Executive Officer of Desert Sun; o when appropriate, members of management, including the President and Chief Executive Officer, are not present for the discussion and determination of certain matters at meetings of the Board of Directors; o under the by-laws of Desert Sun, any two directors may call a meeting of the Board of Directors; o the President and Chief Executive Officer's compensation is considered, in his absence, by the Compensation Committee at least once a year; and o in addition to the standing committees of the Board of Directors, independent committees are appointed from time to time, when appropriate. CHAIRMAN OF THE BOARD OF DIRECTORS The primary roles of the Chairman are to chair all meetings of the Board of Directors and shareholder meetings, and to manage the affairs of the Board of Directors, including ensuring the Board of Directors is organized properly, functions effectively and meets its obligations and responsibilities. The Chairman's responsibilities include, without limitation, ensuring that the Board of Directors works together as a cohesive team with open communication; and working together with the Corporate Governance Committee to ensure that a process is in place by which the effectiveness of the Board of Directors, its committees and its individual directors can be evaluated on a regular basis. The Chairman also acts as the primary spokesperson for the Board of Directors, ensuring that management is aware of concerns of the Board of Directors, shareholders, other stakeholders and the public, and, in addition, ensuring that management strategies, plans and performance are appropriately represented to the Board of Directors. MEETINGS OF THE BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD OF DIRECTORS The Board of Directors meets a minimum of four times per year, and usually meets every quarter and following the annual meeting of Desert Sun's shareholders.

See "Information Concerning the Meeting -- Interests of Certain Persons in the Arrangement". 86 RISK FACTORS In addition to information set out elsewhere, or incorporated by reference, in this Proxy Circular, Desert Sun Shareholders should carefully consider the following risk factors. NATURE OF MINING, MINERAL EXPLORATION AND DEVELOPMENT PROJECTS Desert Sun's mining operations, and exploration and development projects are subject to conditions beyond its control, which can affect the cost of mining for varying lengths of time. Such conditions include environmental hazards, explosions, unusual or unexpected geological formations or pressures, pillar collapses, and periodic interruptions in both production and transportation due to inclement or hazardous weather conditions. Such risks could result in damage to, or destruction of, mineral properties or producing facilities, personal injury, environmental damage, delays in mining, monetary losses and possible legal liability. Desert Sun maintains insurance to cover normal business risks. Mineral exploration is highly speculative in nature, involves many risks and frequently is non-productive. There is no assurance that exploration efforts will continue to be successful. Success in establishing reserves is a result of a number of factors, including the quality of management, Desert Sun's level of geological and technical expertise, the quality of land available for exploration and other factors. Once mineralization is discovered, it may take several years in the initial phases of drilling until production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish proven and probable mineral reserves through drilling, to determine the optimal metallurgical process to extract the metals from the ore and, in the case of new properties, to construct mining and processing facilities. Because of these uncertainties, no assurance can be given that exploration programs will result in the establishment or expansion of mineral resources or mineral reserves. Whether a resource deposit will ultimately be commercially viable depends on a number of factors, including the particular attributes of the deposit such as the deposit's size, its proximity to existing infrastructure, financing costs and the prevailing prices for the applicable resource. Also of key importance are government regulations, including those relating to prices, taxes, royalties, land tenure, land use, the importing and exporting of resource and production plant and equipment, and environmental protection. Development projects have no operating history upon which to base estimates of future cash operating costs. Particularly for development projects, resource estimates and estimates of cash operating costs are, to a large extent, based upon the interpretation of geologic data obtained from drill holes and other sampling techniques, and feasibility studies, which derive estimates of cash operating costs based upon anticipated tonnage and grades of ore to be mined and processed, ground conditions, the configuration of the ore body, expected recovery rates of minerals from the ore, estimated operating costs, anticipated climatic conditions and other factors. As a result, it is possible that actual cash operating costs and economic returns could differ significantly from those estimated for a project before production. It is not unusual for new mining operations to experience problems during the start-up phase, and delays in the commencement of production often can occur. GOLD PRICE The principal business of Desert Sun is the production of gold. Desert Sun's future profitability is largely dependent on movements in the price of gold. Gold prices are affected by numerous factors beyond Desert Sun's control, including central bank sales, producer hedging activities, the relative exchange rate of the United States dollar with other major currencies, global and regional demand, political and economic conditions and production costs and levels in major gold producing regions. In addition, the price of gold has on occasion been subject to rapid short-term changes due to speculative activities. If as a result of a sustained decline in gold prices, revenues from gold sales were to fall below cash operating costs, the feasibility of continuing operations would be evaluated and if warranted, could be discontinued. Desert Sun does not enter into gold price hedging programs, which it would only consider to the extent necessary to satisfy any lender requirements for project finance transactions. 87 CURRENCY FLUCTUATIONS Desert Sun holds cash reserves in both Canadian and United States dollars, and in Brazilian Reais. By virtue of its international operations, Desert Sun incurs costs and expenses in a number of foreign currencies other than the Canadian dollar. The exchange rates covering such currencies have varied substantially and accordingly, could significantly affect the results of the operations of Desert Sun. Desert Sun's future operating results and cash flow will be primarily affected by changes in the United States dollar / Brazilian Real exchange rate as substantially all revenues will be earned in United States dollars, while a substantial portion of the operating (75%) and capital (50%) expenditures are expected to be incurred in Brazilian Reals. The appreciation of the Brazilian Real against the United States dollar continues to be largely dependent on high interest rates in Brazil, which continue to attract significant inflows of foreign capital. Desert Sun believes that as interest rates begin to move lower, the Brazilian Real will begin to weaken. If considered appropriate, Desert Sun may hold surplus cash balances in Brazil in order to take advantage of high local interest rates as an offset to the strength of the Brazilian Real. MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES The estimates for mineral resources and mineral reserves are determined in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, issued by the Canadian Securities Administrators and CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions, adopted by the CIM Council on August 20, 2000 and modified on December 11, 2005. There are numerous uncertainties inherent in estimating mineral resources and mineral reserves, including many factors beyond Desert Sun's control. Such estimation is a subjective process, and the accuracy of any mineral resources and mineral reserves estimate is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation. Differences between management's assumptions, including economic assumptions such as metal prices and market conditions, could have a material effect in the future on Desert Sun's financial position and results of operation. RISK OF CONTINGENT LIABILITIES Desert Sun owns 100% of Jacobina Mineracao e Comercio Ltda. ("JMC"), the Brazilian company that holds the mining and exploration licences, fixed property, and associated plant and equipment at the Jacobina project. In terms of the agreement under which Desert Sun acquired JMC, Valencia Ventures Inc. ("Valencia") provided certain indemnities to Desert Sun for outstanding liabilities. These amounts include taxes payable to the Brazilian Federal and State authorities, liabilities to third parties, as well as labour and health related claims by former employees. Claims relating to silicosis, for the period prior to Desert Sun's acquisition of JMC, for which Valencia has indemnified Desert Sun could amount to approximately $8 to $11.5 million. It is management's belief that the majority of the health related claims are substantially without merit and Desert Sun and Valencia intend to defend the actions vigorously. Valencia did not meet its obligations to Desert Sun under the terms of its indemnity in a consistent manner during the 2005 fiscal year and as a result Desert Sun has written down the value of the balance that it expects to recover from Valencia. COUNTRY RISK, ASSOCIATED WITH DESERT SUN'S OPERATIONAL FOCUS ON BRAZIL All of Desert Sun's property interests are located in Brazil and consequently Desert Sun is subject to certain risks, including currency fluctuations and possible political or economic instability in that country. Mineral exploration and mining activities may be affected to varying degrees by political stability and government regulations relating to the mining industry, including restrictions on production, price controls, export controls, foreign exchange controls, income taxes, expropriation of property, environmental legislation, employment practices and mine safety. Any changes in regulations or shifts in political attitudes are beyond Desert Sun's control and may adversely affect Desert Sun's business. Desert Sun, at present, does not maintain political risk insurance for its foreign operations. 88 LICENSES AND PERMITS, LAWS AND REGULATIONS Desert Sun's mining operations and exploration activities require permits from various government authorities, and are subject to extensive federal, state and local laws and regulations governing prospecting, development, production, exports, taxes, labour standards, occupational health and safety, mine safety and other matters. Such laws and regulations are subject to change, can become more stringent and compliance can therefore become more costly. Desert Sun draws on the expertise and commitment of its management team, their advisors, its employees and contractors to ensure compliance with current laws and fosters a climate of open communication and co-operation with regulatory bodies. Desert Sun believes that it holds all necessary licences and permits under applicable laws and regulations and believes it is presently complying in all material respects with the terms of such licences and permits. However, such licences and permits are subject to change in various circumstances. There can be no guarantee that Desert Sun will be able to maintain or obtain all necessary licences and permits that may be required to explore and develop its properties, commence construction or continue operation of mining facilities. The acquisition of title to mineral concessions in Brazil is a detailed and time consuming process. Title to, and the area of, mining concessions may be disputed. Desert Sun has diligently investigated title to all mineral concessions and obtained title opinions with respect thereto and, based upon such opinions, Desert Sun believes that title to all properties covering the mineral resources and reserves at the Jacobina property is in good standing; however, the foregoing should not be construed as a guarantee of title to those properties. ENVIRONMENTAL Desert Sun's activities are subject to extensive federal, state and local laws and regulations governing environmental protection and employee health and safety. Environmental legislation is evolving in a manner that is creating stricter standards, while enforcement, fines and penalties for non-compliance are more stringent. Environmental assessments of proposed projects carry a heightened degree of responsibility for companies and directors, officers and employees. The cost of compliance with changes in governmental regulations has the potential to reduce the profitability of operations. Desert Sun is also subject to various reclamation-related conditions imposed under federal or state rules and permits. While Desert Sun has budgeted for future capital and operating expenditures to maintain compliance with environmental laws and permits, there can be no assurance that they will not change in the future in a manner that could have a material adverse effect on Desert Sun's financial condition, liquidity or results of operations. UNINSURED RISKS In the course of exploration, development and production of mineral properties, certain risks, and in particular, unexpected or unusual geological operating conditions including rock bursts, cave-ins, fire, flooding and earthquakes may occur. It is not always possible to fully insure against such risks as a result of high premiums or other reasons. Should such liabilities arise, they could reduce or eliminate any future profitability and result in increasing costs and a decline in the value of Desert Sun's securities. COMPETITION Desert Sun competes with many international companies that have substantially greater financial and technical resources than it has for the acquisition of mineral concessions as well as for the recruitment and retention of qualified employees. SHARE PRICE FLUCTUATIONS In recent years, the securities markets in Canada have experienced a high level of price and volume volatility, and the market price of securities of many companies, particularly those considered development stage companies, have 89 experienced wide fluctuations in price that would have not necessarily been related to the operating performance, underlying asset values or prospects of such companies. There can be no assurance that fluctuations in price will not occur. ENFORCEMENT OF CIVIL LIABILITIES As substantially all of Desert Sun's assets and the assets of its subsidiaries are located outside of Canada, and certain of its directors and officers are resident outside of Canada, it may be difficult or impossible to enforce judgments granted by a court in Canada against Desert Sun's assets or the assets of its subsidiaries or its directors and officers residing outside of Canada. DEPENDENCE ON OUTSIDE PARTIES Desert Sun has relied upon consultants, engineers and others and intends to rely on these parties for development, construction and operating expertise. Substantial expenditures are required to construct mines, to establish mineral reserves through drilling, to carry out environmental and social impact assessments, to develop metallurgical processes to extract the metal from the ore and, in the case of new properties, to develop the exploration and plant infrastructure at any particular site. If such parties' work is deficient or negligent or is not completed in a timely manner, it could have a material adverse effect on Desert Sun. CONFLICTS OF INTEREST Certain of Desert Sun's directors and officers serve or may agree to serve as directors or officers of other reporting companies or have significant shareholdings in other reporting companies and, to the extent that such other companies may participate in ventures in which Desert Sun may participate, the directors of Desert Sun may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In the event that such a conflict of interest arises at a meeting of Desert Sun directors, a director who has such a conflict will abstain from voting for or against the approval of such participation or such terms. From time to time several companies may participate in the acquisition, exploration and development of natural resource properties thereby allowing for their participation in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in respect of any one program. It may also occur that a particular Company will assign all or a portion of its interest in a particular program to another of these companies due to the financial position of the Company making the assignment. In determining whether or not Desert Sun will participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider the degree of risk to which Desert Sun may be exposed and its financial position at that time.

[GRAPHIC] LEGAL PROCEEDINGS Desert Sun is not a party to, nor is any of its property the subject of, any legal proceedings or any pending legal proceedings, or, to Desert Sun's knowledge, contemplated legal proceedings, the outcome of which could have a material adverse effect on Desert Sun other than as disclosed in the notes to its audited financial statements for the year ended December 31, 2005. INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS Stan Bharti, the Chairman of the Corporation, is also a director and former officer of Valencia Ventures Inc. ("VVI") (formerly William Multi-Tech Inc. and, prior to that, William Resources Inc.), the entity from which the Corporation acquired the Jacobina property. At the time that Desert Sun and VVI entered into the agreement that entitled Desert Sun to earn a 51% interest in the Jacobina property, Mr. Bharti was not an officer or director of Desert Sun. At the time that VVI granted Desert Sun the option to acquire the remaining 49% interest in the Jacobina property, Mr. Bharti refrained from participating in the negotiations that led to the granting of the option, declared his interest in the matter and refrained from voting at the directors meetings held to approve the granting of the option. For a description of interest of management and others in the Combination, see "Information Concerning the Meeting -- Interests of Certain Persons in the Arrangement" INDEBTEDNESS OF DIRECTORS AND OFFICERS No individual who is, or any time during the most recently completed fiscal year of Desert Sun was, a director, executive officer or senior officer of Desert Sun, nor any associate of any one of them is, or at any time since the beginning of the most recently completed fiscal year of Desert Sun was indebted to Desert Sun or any of its subsidiaries or to another entity, which such indebtedness is, or was at any time during the most recent completed fiscal year of Desert Sun, the subject of a guarantee, support agreement, letter of credit or other similar arrangement or understanding. INTERESTS OF EXPERTS The qualified persons identified herein responsible for the Technical Report hold interests in the Corporation that in the aggregate represent less than one percent of the Corporation's outstanding securities and no qualified person has an interest in the property of the Corporation or its associates or affiliates, nor does any qualified person expect to receive or acquire such interests. 91 CONSENT OF MCGOVERN, HURLEY, CUNNINGHAM, LLP We have read the Management Proxy Circular of Desert Sun Mining Corp.

With respect to Fiduciary Duty or the Duty of Loyalty 1. the fiduciary duty requires a Director to be honest in dealing with other Directors and with the Corporation. In fact, a Director must disclose all information he or she has to the Board. The collegial structure of the Board and the practical delegation of responsibilities to committees will suffer if Directors deprive their fellow Directors of important information they need to carry out their responsibilities and practice due diligence. 2. the fiduciary duty implies a duty of confidentiality. All information about the Board or the Corporation's activities should be presumed to be confidential unless released to the public. 3. Directors may not profit at the expense of the Corporation. They may not divert opportunities or benefits from the Corporation to themselves or put themselves in a position of conflict by competing with the Corporation for business opportunities. 4. Directors must disclose their material interest in a party or contracts and should disclose these interests to the full Board and not just a committee. With respect to the Duty of Care: 1. these responsibilities imply that the Directors attend meetings regularly, read the documents and briefing notes prepared for them prior to the meetings and follow-up on important matters. 2. the business judgement rule protects boards and directors from those that might second-guess their decisions. However, Directors must ensure that the process by which they made a decision ensures that there was adequate information available, agendas and background documents in place, rigorous review and questioning is documented and that in-depth review where warranted is referred to the appropriate committee. Specific Duties of Directors 1. Overseeing and approving a strategy for the business. The Directors, individually and collectively, have the responsibility to participate, in developing and approving the mission of the business, its objectives and goals, and the strategy by which it proposes to reach those goals. Directors must ensure there is congruence between shareholder expectations, company plans and management performance. 2. Management of the Board and selection and oversight of senior management. Directors, individually and collectively, are responsible for managing the Board affairs, including planning its composition, selecting its chair, nominating candidates for election to the Board, appointing committees and determining Director compensation. Directors, individually and collectively, have the responsibility for management succession including the appointment, monitoring and replacement of the CEO as well as CEO compensation. Directors have the responsibility for approving the appointment and compensation of senior management acting upon the advice of the CEO. 3. Monitoring and Acting Directors, individually and collectively, have the responsibility for monitoring the company's performance against goals and revising strategy as appropriate. 4. Approving Policies and procedures for implementing strategy Directors, individually and collectively, have the responsibility for approving all significant policies and procedures and ensuring compliance with all laws and regulations while adhering to the highest ethical and moral standards. 5. Reporting to shareholders on the performance of the business.

Yamana's head office is located at 150 York Street, Suite 1902, Toronto, Ontario, M5H 3S5 and its registered office is located at 2100 Scotia Plaza, 40 King Street West, Toronto, Ontario, M5H 3C2. PRINCIPAL SUBSIDIARIES The following chart illustrates the principal subsidiaries of Yamana (collectively, the "Subsidiaries"), together with the jurisdiction of incorporation of each company and the percentage of voting securities beneficially owned or over which control or direction is exercised by Yamana: [GRAPHIC] ----------- Note: (1) Balance of 40% is held in escrow pursuant to an escrow agreement dated April 5, 2004 to be transferred to RNC (Panama) Limited in the event that the mine is constructed and put into production by February 2007. As used in this Proxy Circular, except as otherwise required by the context, reference to the "Yamana" means, collectively, Yamana Gold Inc. and the Subsidiaries. OVERVIEW OF BUSINESS Yamana is engaged in the operation, development, exploration and acquisition of mineral properties in Brazil, and Central America. Yamana is an intermediate gold producer with a previously stated objective to achieve sustainable production of 750,000 ounces of annual gold production by 2008 in addition to copper production from the Chapada copper-gold property. As a result of the completion of the Arrangement, Yamana will strengthen its position as an intermediate gold producer and now expects to exceed its strategic goal of producing 750,000 ounces of gold by 2008 with projected production in that year now targeted to exceed 800,000 ounces. Upon the completion of the Arrangement, Yamana will have added a producing mine, the Jacobina mine in Brazil, to its existing mineral projects. In addition, Yamana will own the prospective exploration ground surrounding Desert Sun's Jacobina mine and, in particular, the Morro do Vento and Canaveiras projects. Yamana currently operates the Fazenda Brasileiro gold mine in Bahia State, Brazil, the Fazenda Nova gold mine in Goias State, Brazil and the Sao Francisco gold mine in Mato Grosso State, Brazil. At Sao Francisco, the open pit pre-strip is complete and the mining of ore commenced in December 2005. Ore is being loaded onto the heap leach pads and it is expected that 800,000 tonnes of ore will be stacked by the end of February 2006. The primary, secondary and tertiary crushing circuits as well as the gravity processing circuit are operational. The gravity heap leach project is expected to be fully operational before the end of the first quarter of 2006. Yamana is constructing its Chapada copper-gold mine in Goias State and expects to commence mining operations at Chapada by the end of 2006. Yamana also holds the feasibility study stage Sao Vicente gold property in Mato Grosso, the pre-feasability study stage C-1 Santa Luz project in Bahia and the late exploration stage project Ernesto in addition to significant exploration land packages in the Santa Elina and Itapicuru gold belts. Pursuant to its acquisition of RNC Gold Inc., Yamana added two producing mines, La Libertad in Nicaragua and San Andres in Honduras, to its existing mineral projects. It also owns 60% of the Cerro Quema project in Panama, a development stage property, and the exploration ground surrounding the Bonanza mine in Nicaragua, with a two-year option to purchase the Bonanza mine. An operating licence from the Brazilian Departmento Nacional da Producao Mineral (the "DNPM") is required to operate a mine in Brazil. An operating licence will only be issued by the DNPM after construction of a mine is completed. However, the DNPM grants temporary operating licences during the period in which an application for an operating licence is pending. Yamana operates under ordinary course licences and the formal operating licence for Sao Francisco, which has only recently been completed, is pending. Yamana has started operations at Sao Francisco and is in the normal start up phase of a mine. On February 28, 2006, Yamana sold its interests in certain exploration gold properties in the eastern part of Santa Cruz Province in the Patagonia region of Argentina through the sale of its wholly-owned Argentina subsidiary, Recursos Yamana S.A. Yamana is actively pursuing growth opportunities involving the acquisition of mineral exploration, development or production assets through the acquisition of such interests directly or by way of acquisitions of other mining companies with such assets. Yamana is currently engaged in discussions with respect to such opportunities. At any given time, discussions and activities can be in process on a number of different initiatives, each at different stages of evaluation and negotiation. Other than the Combination with Desert Sun, Yamana currently does not have any binding agreements or commitments to enter into any such transaction. There is no assurance that any potential transaction will be successfully completed. RECENT DEVELOPMENTS ACQUISITION OF RNC GOLD INC. On February 28, 2006, Yamana completed a plan of arrangement with RNC, pursuant to which it acquired all of the outstanding shares of RNC. Pursuant to the terms of the acquisition, Yamana issued 0.12 of a Yamana Share in exchange for each outstanding common share of RNC. In connection with the acquisition of RNC, Yamana entered into a senior secured credit facility agreement dated as of December 4, 2005 with RNC extending a loan of approximately US$18.9 million in order to facilitate RNC's purchase of a 75% interest in the San Andres gold mine in Honduras. Yamana exercised RNC's option to purchase the remaining 25% interest in the San Andres mine for consideration equal to US$4 million which was paid through the issuance of 872,093 Yamana Shares. As a result of the acquisition of RNC, Yamana acquired two producing mines, La Libertad in Nicaragua and San Andres in Honduras, to add to its existing mineral projects. Yamana also acquired prospective exploration ground surrounding RNC's Hemco mine in Nicaragua, with a two-year option to purchase the Hemco mine. The completion of the RNC acquisition has strengthened Yamana's position as an intermediate gold producer and has moved Yamana closer to accomplishing its strategic goal of producing 750,000 ounces of gold by 2008. SAO VICENTE FEASIBILITY STUDY In May 2005, Yamana announced the results of a positive feasibility study (the "Feasibility Study") completed in respect of its Sao Vicente gold project in Mato Grosso State, Brazil, prepared by Minerconsult Engenharia Ltda, incorporating specific data supplied by Independent Mining Consultants, Inc., Kappes, Cassiday Associates and Metago. The Feasibility Study is summarized in a technical report on the Sao Vicente Gold Project, Mato Grosso State, Brazil, dated as of June 16, 2005 (the "Technical Report"), prepared for Yamana by Michael G. Hester, Vice President and Principal Mining Engineer of Independent Mining Consultants, Inc. and by Ivan C. Machode, P.Eng., Principal of TechoMine Services LLC, each of whom is a qualified person as defined in NI 43-101. The Feasibility Study is an update to the prior preliminary feasibility study completed by Watts, Griffis and McOuat Limited in July 2003, which was completed based on prior data collected before the current exploration efforts of Yamana at Sao Vicente. The results of the Feasibility Study confirm an increase in mineral reserves at Sao Vicente of 26%, with an increase in forecast gold production of 25% to 174,380 ounces. The initial plan for Sao Vicente contemplated treating Sao Vicente and Sao Francisco on a combined basis; however, the results of the Feasibility Study support Yamana later conclusion that Sao Vicente can be constructed as a stand alone project. Based on positive results to date from continuing exploration at Sao Vicente, Yamana has decided to defer a formal construction decision pending further exploration results and further feasibility evaluation to optimize the project. NEWLY DISCOVERED AREA AT FAZENDA BRASILEIRO MINE In early June 2005, Yamana announced the discovery of a new mineralized zone within the Fazenda Brasileiro mine in Bahia State, Brazil. Results for the first seven of 22 drill holes were provided and all seven holes hit high grade intercepts starting at 48 metres depth and located generally within 50 metres of existing mine workings. This C-Quartz discovery cross cuts the mine sequence and represents an entirely new target type for the mine. The C-Quartz structure is currently being explored with a two-phase drilling program. Although initial results have been encouraging, there is currently not enough data to support a mineral reserve or mineral resource estimate at C Quartz, and Yamana cannot ensure that this discovery will result in additional reserves or resources at Fazenda Brasileiro. EXPLORATION UPDATE Yamana's exploration efforts in Brazil include: (i) further drilling at Ernesto, a property located approximately 65 kilometres south of the Sao Francisco project, after an initial mineral resource estimate was determined (measured and indicated mineral resources of 845,566 tonnes at an average grade of 8.07 grams of gold per tonne and an inferred mineral resource of 510,646 tonnes at a grade of 5.98 grams of gold per tonne); and (ii) further drilling and bulk sampling at Sao Vicente Deep South and at C-1 Santa Luz. Ernesto and Sao Vicente Deep South are high priority targets on Yamana's 750,000 hectares of mineral claims on the Santa Elina Gold Belt. C-1 Santa Luz is one of eight priority targets on Yamana's 150,000 hectares of mineral claims on the Rio Itapicuru Greenstone Belt. These projects are subject to completion of either feasibility studies or favourable construction decisions. Development of these projects is anticipated to be sequential, however, whether or not they are developed, or are developed in sequence, will depend on results from continuing exploration efforts and scoping and feasibility studies. Current internal estimates and completed scoping studies suggest that these projects could contribute in excess of an additional 225,000 ounces of gold production beginning late 2007 or early 2008. However, there is no assurance that all or any of them will be developed nor that they will be developed within the periods contemplated herein. LOAN UPDATE On April 29, 2005, Yamana drew down under its previously announced $100 million loan facility and the lender advanced the funds. Upon drawdown, the funds were deposited in escrow for the benefit of Yamana pending perfection and registration of security interests and receipt of certain authorizations, approvals and opinions relating to the perfection and registration of such security interests. The period for perfection and registration of security interests varied depending on the collateral class and registration process. To accommodate the applicable registration process, Yamana and the lender under the facility provided for a two-staged release from escrow. On August 8, 2005, the first $70 million was released to Yamana and the remaining $30 million was released on October 7, 2005. The loan is governed by an amended and restated trust indenture between Yamana and BNY Trust Company of Canada dated as of April 19, 2005 as supplemented and amended. WARRANT TRANSACTION As of July 29, 2005, Yamana effected an amendment of the terms of its 40,567,656 listed common share purchase warrants (the "Yamana Listed Warrants") in order to encourage the early exercise of the Yamana Listed Warrants, each of which was exercisable to purchase one Yamana Share at a price of Cdn.$1.50 until July 31, 2008. A total of 39,866,635 Yamana Listed Warrants were exercised during a 30-day voluntary early exercise period expiring on August 29, 2005 at a rate of 1.0356 Common Shares for each Warrant exercised at the exercise price of Cdn.$1.50. An aggregate of 41,285,875 Yamana Shares were issued pursuant to the early exercise of the Warrants. Upon the expiry of the voluntary early exercise period, the remaining 701,021 Yamana Listed Warrants were automatically exchanged, without payment of the exercise price or any additional consideration, at a rate of 0.6793 of a Yamana Share for each Warrant exchanged. An aggregate of 476,198 Yamana Shares were issued pursuant to the automatic exchange of Warrants. The net proceeds realized by Yamana in connection with the Warrant transaction were approximately Cdn.$58,000,000. APPOINTMENT OF NEW DIRECTORS On June 16, 2005, Nigel Lees was appointed as a director of Yamana. Mr. Lees has over 25 years experience in the investment banking industry in Canada and the United Kingdom. He is currently the President of C.N.

Sprott Securities has also participated in certain discussions and negotiations among representatives of the Company and Yamana and their financial advisors. Sprott Securities has not, to the best of its knowledge, been denied access by the Company to any information requested by Sprott Securities. This fairness opinion has been prepared in accordance with the Disclosure Standards for Formal Valuations and Fairness Opinions of the Investment Dealers Association of Canada but the Association has not been involved in the preparation or review of this fairness opinion. ASSUMPTIONS AND LIMITATIONS With the approval of the Board and as is provided for in the Engagement Letter, Sprott Securities has relied upon the completeness, accuracy and fair presentation of all of the financial and other information, data, advice, opinions and representations obtained by it from publicly-available sources, the Board and from the Company's officers and directors (collectively, the "Information"). With respect to the financial forecasts provided by the Company, Sprott Securities has assumed and relied that they have been reasonably prepared on bases reflecting the best currently available estimates and judgements of the future financial performance of the Company. The Fairness Opinion is conditional upon the completeness, accuracy and fair presentation of such Information. Subject to the exercise of professional judgement and except as expressly described herein, Sprott Securities has not attempted to independently verify or investigate the completeness, accuracy or fair presentation of any of the Information. In addition, Sprott Securities has assumed that the Transaction will be consummated in accordance with the terms set forth in the draft Support Agreement without any waiver, amendment or delay of any terms or conditions. The Company has represented to Sprott Securities in a certificate delivered as of the date of this Fairness Opinion, among other things, that (a) The information, data and other material (financial and otherwise) provided orally by, or in the presence of, an officer of the Company or in writing by the Company or their respective agents to Sprott Securities relating to the Company or the Transaction for the purpose of preparing this Fairness Opinion was, at the date such information was provided to Sprott Securities, and is, complete, true and correct in all material respects, and did not and does not contain any untrue statement of a material fact in respect of the Company or the Transaction and did not and does not omit to state a material fact in respect of the Company or the Transaction necessary to make such information not misleading in light of the circumstances under which it was made or provided; (b) since the dates on which information was provided to Sprott Securities by the Company, except as disclosed in writing to Sprott Securities or in a public filing with securities regulatory authorities, there has been no material change, financial or otherwise, in the financial condition, assets, liabilities (contingent or otherwise), business, operations or prospects of the Company or any of its subsidiaries and no material change has occurred which would have or which would reasonably be expected to have a material effect on this Fairness Opinion; (c) to the best of the Company's knowledge, information and belief after due inquiry, there are no independent appraisals or valuations or material non-independent appraisals or valuations relating to the Company or any of its subsidiaries or any of their respective material assets or liabilities which have been prepared as of a date within the two years preceding the date hereof and which have not been provided to Sprott Securities; and (d) since the dates on which information was provided to Sprott Securities by the Company, no material transaction has been entered into by the Company or any of its subsidiaries or contemplated by the Company or any of its affiliates except for transactions that have been disclosed to Sprott Securities or generally disclosed. This Fairness Opinion is rendered on the basis of securities markets, economic, financial and general business conditions prevailing as at the date hereof and the condition and prospects, financial and otherwise, of the Company and its subsidiaries and affiliates, as they were reflected in the Information and as they have been represented to Sprott Securities in discussions with management of the Company. In its analyses and in preparing this Fairness Opinion, Sprott Securities has made numerous assumptions with respect to expected industry performance, general business and economic conditions and other matters, many of which are beyond the control of Sprott Securities or any party involved in the Transaction. Sprott Securities believes these assumptions are reasonable under the current circumstances; however, actual future results may demonstrate that certain assumptions were incorrect. Sprott Securities is an investment dealer and financial advisor only and has relied upon, without independent verification or investigation, the assessment of the Company with respect to legal, tax, regulatory and actuarial matters. Sprott Securities has not made any independent valuation or appraisal of any specific assets or liabilities of the Company. This Fairness Opinion has been provided for the exclusive use of the Board in connection with the Transaction. This Fairness Opinion may not be used by any person or relied upon by any other person other than the Board of Directors and may not be used or relied upon by the Board for any purpose other than the purpose hereinbefore stated, without the express prior written consent of Sprott Securities. Under the terms of its engagement, Sprott Securities has consented to the reference to Sprott Securities and the description of, reference to and reproduction of this Fairness Opinion in any management information circular or other disclosure document(s) prepared in connection with the Transaction for filing with regulatory authorities or delivery to the Company's shareholders. This Fairness Opinion is limited to the fairness, from a financial point of view, to the shareholders of the Company and Sprott Securities expresses no opinion as to any alternative transaction. Sprott Securities expresses no opinion as to the fairness of the Transaction relative to the consideration offered under any proposed alternative transaction. The Fairness Opinion does not constitute a recommendation to any shareholder of the Company as to whether such shareholder should tender to the Transaction or how such shareholder should vote should vote with respect to the Transaction should the Transaction or any other matter come to a vote of the Company's shareholders. In addition, pursuant to the Engagement Letter, Sprott Securities has not been asked to address, and this Fairness Opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, any creditors or any other constituencies of the Company, other than the holders of the Company's common shares. Sprott Securities believes that this Fairness Opinion must be considered and reviewed as a whole and that selecting portions of the stated analyses or factors considered by Sprott Securities, without considering all the stated analyses and factors together, could create a misleading view of the process underlying or the scope of the Fairness Opinion. The preparation of a fairness opinion of this nature is a complex process and is not necessarily amenable to partial analysis or summary description. Any attempt to do so could lead to undue emphasis on any particular factor or analysis. The Fairness Opinion is given as of the date hereof, and Sprott Securities disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Fairness Opinion which may come or be brought to Sprott Securities' attention after the date hereof. Without limiting the foregoing, in the event that there is any material change (as defined in the Securities Act (Ontario)) in the Company or any change in any material fact (as defined in the Securities Act (Ontario)) affecting the Fairness Opinion after the date hereof, Sprott Securities reserves the right to change, modify or withdraw the Fairness Opinion. FAIRNESS CONSIDERATIONS The assessment of fairness, from a financial point of view, must be determined in the context of the particular transaction. In its assessment, Sprott Securities looked at several techniques and used a blended approach to determine its opinion on the Transaction. Sprott Securities based its Fairness Opinion upon a number of quantitative and qualitative factors including, but not limited to: 1. the trading metrics of selected publicly-traded, comparable companies in Canada and the United States; 2. the historical trading range for the Company's common shares; 3. the form of consideration that the shareholders of the Company are expected to receive from Yamana as described in the Support Agreement; 4. the qualitative and quantitative assessments and determinations made by Sprott Securities regarding the present value of the Company's expected future operating results including an assessment of the expected values to be realized by the Company's shareholders as well as an assessment of the sensitivity of the variables considered to the general results determined by Sprott Securities' analyses; 5. the historical acquisitions recently completed and pending in the industry and comparative valuation metrics; and 6. the likelihood and probability of the Company finding a higher or better offer for its common shares in the context of the Company's current and expected situation while also considering the current and expected market for the equity capital of organizations in the mining industry. Sprott Securities did not, in considering the fairness of the Transaction from a financial point of view, assess any income tax consequences that any particular shareholder may face as a result of the Transaction. FAIRNESS OPINION Based on and subject to the foregoing, Sprott Securities is of the opinion that, as at the date hereof, the consideration to be offered to the holders of the Company's common shares pursuant to the Transaction, is fair, from a financial point of view, to shareholders of Desert Sun. Yours very truly, SPROTT SECURITIES INC. (Signed) SPROTT SECURITIES INC. EXHIBIT D GMP FAIRNESS OPINION [GRAPHIC] GMP Securities L.P. 145 King Street West, Suite 1100 Toronto, Ontario M5H 1J8 Tel: (416) 367-8600 Fax: (416) 943-6160 www.gmpsecurities.com February 20, 2006 The Special Committee of the Board of Directors Desert Sun Mining Corp. 65 Queen Street West, Suite 810 Toronto, Ontario, M5H 2M5 To the Special Committee of the Board of Directors: GMP Securities L.P. ("GMP") understands that Desert Sun Mining Corp. ("Desert Sun" or the "Corporation") and Yamana Gold Inc. ("Yamana") are proposing a business combination by way of a plan of arrangement whereby Desert Sun shareholders will receive 0.6 of a common share of Yamana in exchange for each common share of Desert Sun (the "Arrangement"). The special committee of the Board of Directors of Desert Sun (the "Special Committee") has requested GMP's fairness opinion (the "GMP Fairness Opinion") with respect to the fairness of the Arrangement, from a financial point of view, to the shareholders of Desert Sun (the "Desert Sun Shareholders"). The GMP Fairness Opinion is provided pursuant to GMP's engagement by Desert Sun to provide financial advice to the Special Committee of Desert Sun under a letter agreement dated February 14, 2006 (the "Engagement"). GMP ENGAGEMENT Under the Engagement, among other advice and services, GMP is to assist the Special Committee in evaluating the Arrangement and to determine whether the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders. Subject to the terms of the Engagement, GMP consents to the inclusion of the GMP Fairness Opinion, with a summary thereof in a form acceptable to GMP, in a management information circular to be sent to Desert Sun Shareholders in connection with the Arrangement and the filing thereof by Desert Sun with the applicable securities regulatory authorities. RELATIONSHIPS WITH INTERESTED PARTIES GMP has previously acted as an underwriter to Desert Sun. The most recent financing for which GMP acted for Desert Sun was in December 2005, in which GMP was a syndicate member in a unit offering which raised gross proceeds of $40 million. GMP has also been a syndicate member in three other offerings of units or common shares prior to December 2005, which raised total gross proceeds of $51.2 million. GMP is not an insider, associate or affiliate (as such terms are defined under applicable securities legislation) of Desert Sun or Yamana or any of their affiliates or associates. The fees payable to GMP by Desert Sun arising from the Engagement are not contingent upon the successful completion of the Arrangement or the conclusions reached by GMP herein. There are no understandings, agreements or commitments between GMP and Desert Sun, Yamana or any of their respective affiliates or associates with respect to any future business dealings. However, GMP may in the future, in the ordinary course of business, seek to perform financial advisory or investment banking services for any one or more of them from time to time. GMP acts as a trader and investment dealer, both as principal and agent, in all major Canadian financial markets and, accordingly, GMP and its clients may have, or may in the future have, long or short positions in securities of Desert Sun, Yamana or their respective affiliates or associates and, from time to time, GMP may have executed or may execute transactions on behalf of Desert Sun or Yamana or on behalf of other clients for which it receives compensation. As an investment dealer, GMP conducts research on securities and may, in the ordinary course of business, provide research reports and investment advice to its clients on investment matters, including matters involving an investment in Desert Sun or Yamana. CREDENTIALS OF GMP SECURITIES L.P. GMP is a wholly-owned subsidiary of GMP Capital Trust which is a publicly traded income trust listed on the Toronto Stock Exchange. GMP has offices in Toronto, Calgary and Montreal, Canada and Geneva, Switzerland. GMP is one of the largest independent Canadian investment banking firms involved in corporate finance, mergers & acquisitions, equity sales and trading and investment research. As part of our investment banking activities, we are regularly engaged in the valuation of securities in connection with mergers and acquisitions, public offerings and private placements of listed and unlisted securities and regularly engage in market making, underwriting and secondary trading of securities in connection with a variety of transactions. GMP is not in the business of providing auditing services and is not controlled by a financial institution. SCOPE OF REVIEW In connection with the GMP Fairness Opinion, GMP has reviewed and relied upon, among other things, the following: 1. internal mineral resource, production and capital estimates, mine plans and operating and financial projections of the Corporation and Yamana; 2. audited financial statements of the Corporation and Yamana for the fiscal years ended December 31, 2003 and December 31, 2004; 3. unaudited interim financial statements of the Corporation and Yamana for the three months ended March 31, 2005, for the six months ended June 30, 2005 and for the nine months ended September 30, 2005; 4. published research and industry reports for the Corporation and Yamana and for the worldwide metals and mining industry; 5. public information relating to the business, operations, financial performance and stock trading history of the Corporation and Yamana and other selected public companies considered by GMP to be relevant; 6. press releases issued by the Corporation and Yamana; 7. public filings submitted by the Corporation and Yamana to securities commissions or similar regulatory authorities and stock exchanges in Canada; 8. public information with respect to other transactions considered by GMP to be relevant; 9. discussions with senior officers and directors of Yamana and Desert Sun; 10. a draft copy of the arrangement agreement between Desert Sun, Yamana and 6524338 Canada Inc. with respect to the Arrangement; 11. a representation certificate as to certain factual matters dated as of February 20, 2006, provided by senior management of Desert Sun and addressed to us; and 12. such other corporate, industry and financial market information, investigations and analyses as GMP considered necessary or appropriate in the circumstances. GMP has not, to the best of its knowledge, been denied access by the Corporation to any information requested. GMP did not meet with the auditors of the Corporation or Yamana and has assumed the accuracy and fair presentation of the audited consolidated financial statements of the Corporation and Yamana and the reports of the auditors thereon and of the unaudited interim financial statements of the Corporation and Yamana referred to above. APPROACH TO ANALYSIS In connection with the GMP Fairness Opinion, GMP has performed a variety of financial and comparative analyses, including those described below. In arriving at the GMP Fairness Opinion, GMP has attributed greater weight to certain analyses and factors that it deemed appropriate based on GMP's experience in rendering such opinions. Specifically, GMP has attributed more weight to the historical trading and net asset value analyses as GMP considers those methodologies to provide a more reliable comparison of relative values than the precedent transactions and comparable trading multiples analyses. GMP considered, among other factors, the following items and methodologies, both relative to the Corporation and Yamana and to their peer group: i) historical trading analyses; ii) net asset value analysis; and iii) precedent transaction and trading multiple analyses. i) Historical Trading Analyses GMP reviewed historical trading price ranges of the Corporation's and Yamana's common shares both from a simple price perspective (intraday and closing prices) and from a volume weighted average price perspective. GMP also reviewed premiums paid over historical trading prices in other comparable transactions. ii) Net Asset Value ("NAV") Analysis The net asset value analysis assesses the value of the Corporation's and Yamana's assets less any liabilities. In order to determine the values of the assets, GMP used a discounted cash flow ("DCF") approach for those assets in production and applied a value to the resources that are outside of the mine's production profile in line with market comparables. The DCF approach considers the present value of the future cash flows generated by a mine, which takes into account the timing and relative certainty of projected cash flows and requires that certain assumptions be made regarding, among other things, production rate, capital costs, operating costs, gold prices, discount rates and terminal values. Once the total value of the assets was determined, the Corporation's or Yamana's (as applicable) liabilities were then subtracted to determine the NAV. An appropriate discount rate was selected based on GMP's experience in valuing gold mining companies. The discount rate reflects the risk associated with the projected cash flows and incorporates factors including, but not limited to, the risk-free rate, risks associated with mining, as well as non-mining risks such as country risk. To complete the DCF analysis, GMP did not rely on any single series of projected cash flows but performed a variety of sensitivity analyses. Variables sensitized included, but were not limited to, discount rates, gold prices, and operating costs. iii) Precedent Transactions and Trading Multiple Analyses GMP reviewed publicly available information on selected transactions and trading multiples involving other gold mining companies and compared those to the trading multiples of Desert Sun and Yamana, as well as the exchange ratio for the Arrangement. The analysis of those precedent transactions and trading multiples are not purely mathematical but rather involves considerations and judgements concerning, among other things, differences in the comparable transactions and trading multiples, risks associated with each company, past performance, state of the economy and the gold market, and other factors. ASSUMPTIONS AND LIMITATIONS With the Special Committee's approval, GMP has relied upon the completeness, accuracy and fair presentation of all of the financial and other information, data, advice, opinions or representations obtained by it from public sources, senior management of the Corporation, and their consultants and advisors (collectively, the "Information"). The GMP Fairness Opinion is conditional upon such completeness, accuracy and fair presentation of such Information. Subject to the exercise of professional judgement and except as expressly described herein, GMP has not attempted to verify independently the completeness, accuracy or fair presentation of any of the Information. Senior officers of the Corporation have represented to GMP in a certificate delivered as of the date hereof, among other things, that (i) the Information provided orally by, or in the presence of, an officer or employee of the Corporation or in writing by the Corporation to GMP relating to the Corporation and the Arrangement for the purpose of preparing this GMP Fairness Opinion was, at the date the Information was provided to GMP, and is, except as has been disclosed in writing to GMP, complete, true and correct in all material respects, and did not and does not contain any untrue statement of a material fact (as such term is defined in the Securities Act (Ontario) the ("Act")) in respect of the Corporation or the Arrangement, necessary to make the Information not misleading in light of the circumstances under which the Information was made or provided; and (ii) since the dates on which the Information was provided to GMP, except as disclosed in writing to GMP, there has been no material change (as such term is defined in the Act), financial or otherwise, in the financial condition, assets, liabilities (contingent or otherwise), business, operations or prospects of the Corporation and no material change has occurred in the Information or any part thereof which would have or which would reasonably be expected to have a material effect on the GMP Fairness Opinion. The GMP Fairness Opinion is rendered on the basis of securities and commodities markets, economic, financial and general business conditions prevailing as at the date hereof and the condition and prospects, financial and otherwise, of the Corporation and its subsidiaries and affiliates, as they were reflected in the Information and as they have been represented to GMP in discussions with management of the Corporation. In its analyses and in preparing the GMP Fairness Opinion, GMP made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of GMP or any party involved in the Arrangement. GMP is acting as financial advisor to the Corporation and will receive a fee from the Corporation for its services, including the delivery of this GMP Fairness Opinion. In addition, the Corporation has agreed to indemnify GMP, its affiliates and their respective officers, directors, employees, partners, agents, advisors and shareholders against certain liabilities that may arise from the Engagement. The GMP Fairness Opinion is not, and should not be construed as, a valuation of Desert Sun, Yamana, or any of the assets or securities thereof. Furthermore, the GMP Fairness Opinion is not, and should not be construed as, advice as to the price at which shares of the Corporation or Yamana (before or after completion of the Arrangement) may trade at any future date. This GMP Fairness Opinion is not to be construed as a recommendation to any holder of common shares as to whether to vote in favour of the Arrangement. The GMP Fairness Opinion has been provided for the use of the Special Committee of the Corporation and may not be used by any other person or relied upon by any other person other than the Special Committee and the Corporation without the express prior written consent of GMP. The GMP Fairness Opinion is given as of the date hereof and GMP disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the GMP Fairness Opinion that may come or be brought to GMP's attention after the date hereof. Without limiting the foregoing, in the event that there is any material change in any fact or matter affecting the GMP Fairness Opinion after the date hereof, GMP reserves the right to change, modify or withdraw the GMP Fairness Opinion. GMP believes that its analyses must be considered as a whole and that selecting portions of the analyses or the factors considered by GMP, without considering all factors and analyses together, could create a misleading view of the process underlying the GMP Fairness Opinion. The preparation of an opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Any attempt to do so could lead to undue emphasis on any particular factor or analysis. CONCLUSION Based on and subject to the foregoing, GMP is of the opinion that, as of the date hereof, the Arrangement is fair, from a financial point of view, to the Desert Sun Shareholders.

("Desert Sun") and such other matters pertaining to a proposed arrangement (the "Arrangement") involving Desert Sun, as described below; (b) A Final Order of the Superior Court of Justice pursuant to section 192 of the CBCA approving the Arrangement if it is adopted and approved by the common shareholders of Desert Sun (the "Desert Sun Shareholders") at the Meeting; and (c) Such further and other relief as to this Honourable Court seems just. 2. THE GROUNDS FOR THE APPLICATION ARE: (a) Desert Sun is a Canadian gold mining company engaged in gold production and the acquisition, exploration and development of mineral properties in Brazil and is a corporation existing under the CBCA.

Commercial List Court No.: 06-CL-6308 ONTARIO SUPERIOR COURT OF JUSTICE COMMERCIAL LIST Proceeding commenced at TORONTO NOTICE OF APPLICATION Cassels Brock & Blackwell LLP Scotia Plaza, Suite 2100 40 King Street West Toronto, Ontario M5H 3C2 Robert B. Cohen LSUC#: 32187D Tel: 416-869-5425 Fax: 416-350-6929 Solicitors for the Applicant EXHIBIT I DISSENT RIGHTS Section 190 of the CBCA provides registered shareholders with the right to dissent from certain resolutions which effect extraordinary corporate transactions or fundamental corporate changes. The Interim Order expressly provides Registered Desert Sun Shareholders with the right to dissent from the Arrangement Resolution pursuant to section 190 of the CBCA, with modifications to the provisions of section 190 as provided in the Plan of Arrangement and the Interim Order. Any Registered Desert Sun Shareholder who dissents from the Arrangement Resolution in compliance with section 190 of the CBCA as modified by the Plan of Arrangement and the Interim Order will be entitled, in the event the Arrangement becomes effective, to be paid the fair value of Desert Sun Shares held by such Dissenting Shareholder determined as of the close of business on the day before the Final Order is effective. Pursuant to the Interim Order, once determined, the fair value will be paid only in cash, subject to pro-ration. Section 190 of the CBCA provides that there is no right of partial dissent and, accordingly, a shareholder may only make a claim under that section with respect to all the shares of a class held by the shareholder on behalf of any one beneficial owner and registered in the shareholder's name. One consequence of this provision is that a Registered Desert Sun Shareholder may only exercise the right to dissent under section 190 (as modified by the Plan of Arrangement and the Interim Order) in respect of Desert Sun for Desert Sun Shares that are registered in that shareholder's name. In many cases, shares beneficially owned by a non-registered shareholder are registered either (a) in the name of an Intermediary or (b) in the name of a clearing agency (such as CDS) of which the Intermediary is a participant. Accordingly, a Non-Registered Shareholder will not be entitled to exercise the right to dissent under section 190 directly (unless the shares are re-registered in the Non-Registered Shareholder's name). A Non-Registered Shareholder who wishes to exercise the right to dissent should immediately contact the Intermediary with whom the Non-Registered Shareholder deals in respect of the shares and either (i) instruct the Intermediary to exercise the right to dissent on the Non-Registered Shareholder's behalf (which, if the shares are registered in the name of CDS or other clearing agency, may require that the shares first be re-registered in the name of the Intermediary), or (ii) instruct the Intermediary to re-register the shares in the name of the Non-Registered Shareholder, in which case the Non-Registered Shareholder would be able to exercise the right to dissent directly. A Registered Desert Sun Shareholder who wishes to dissent must provide to Desert Sun, at 65 Queen Street West, Suite 800 Toronto, Ontario M5H 2M5 or by facsimile transmission to (416) 861-8165, attention Tony Wonnacott on or before 5:00 p.m. (Toronto time) on the Business Day preceding the Meeting (or any adjournment or postponement thereof), written objection to the special resolution (a "Dissent Notice"), with copy to CIBC Mellon to facsimile number (416) 643-5501 (Attention: Stock Transfer Services). It is important that Registered Desert Sun Shareholders strictly comply with this requirement, which is different from the statutory dissent provisions of the CBCA. The filing of a Dissent Notice does not deprive a Registered Desert Sun Shareholder of the right to vote at the Meeting; however, the CBCA provides, in effect, that a Registered Desert Sun Shareholder who has submitted a Dissent Notice and who votes in favour of the Arrangement Resolution will no longer be considered a Dissenting Shareholder with respect to that class of shares voted in favour of the Arrangement Resolution. The CBCA does not provide, and Desert Sun will not assume, that a vote against the Arrangement Resolution or an abstention constitutes a Dissent Notice, but a Registered Desert Sun Shareholder need not vote their Desert Sun for Desert Sun Shares against the Arrangement Resolution in order to dissent. Similarly, the revocation of a proxy conferring authority on the proxyholder to vote in favour of the Arrangement Resolution does not constitute a Dissent Notice; however, any proxy granted by a Registered Desert Sun Shareholder who intends to dissent, other than a proxy that instructs the proxyholder to vote against the Arrangement Resolution, should be validly revoked in order to prevent the proxyholder from voting such Desert Sun for Desert Sun Shares in favour of the Arrangement Resolution and thereby causing the Registered Desert Sun Shareholder to forfeit their dissent rights. See "General Proxy Information -- Revocation of Proxies". Yamana is required, within ten days after Desert Sun Shareholders adopt the Arrangement Resolution, to send a notice to each shareholder who has filed a Dissent Notice that the Arrangement Resolution has been adopted. Such notice is not required to be sent to any Desert Sun Shareholder who voted for the Arrangement Resolution or who has withdrawn their Dissent Notice. A Dissenting Shareholder who has not withdrawn their Dissent Notice must then, within 20 days after receipt of notice that the Arrangement Resolution has been adopted, send to Desert Sun (with copy to CIBC Mellon) a written notice (a "Demand for Payment") containing their name and address, the number of Desert Sun for Desert Sun Shares in respect of which they dissent, and a demand for payment of the fair value of such shares. Within 30 days after sending the Demand for Payment, the Dissenting Shareholder must send to Desert Sun (with a copy to CIBC Mellon) certificates representing Desert Sun for Desert Sun Shares in respect of which they dissent. A Dissenting Shareholder who fails, within the appropriate time frame, to send a Dissent Notice, a Demand for Payment and certificates representing Desert Sun for Desert Sun Shares in respect of which they dissent has no right to make a claim under section 190 of the CBCA. Desert Sun or CIBC Mellon will endorse on share certificates received from a Dissenting Shareholder a notice that the holder is a Dissenting Shareholder and will forthwith return the share certificates to the Dissenting Shareholder. After sending a Demand for Payment, a Dissenting Shareholder ceases to have any rights as a Desert Sun Shareholder in respect of the Desert Sun for Desert Sun Shares in respect of which the shareholder has dissented other than the right to be paid the fair value of the shares as determined pursuant to the Interim Order, unless (i) the Dissenting Shareholder withdraws their Dissent Notice before Desert Sun makes a written offer to pay in accordance with subsection 190(12) of the CBCA (an "Offer to Pay"), (ii) Desert Sun fails to make an Offer to Pay and the Dissenting Shareholder withdraws their Demand for Payment, or (iii) the Desert Sun Board of Directors revokes the Arrangement Resolution, in which case the Dissenting Shareholder's rights as a shareholder will be reinstated. Yamana is required, not later than seven days after the later of the Effective Date or the date on which Yamana received the Demand for Payment of a Dissenting Shareholder, to send to each Dissenting Shareholder who has sent a Demand for Payment an Offer to Pay for their Desert Sun for Desert Sun Shares in an amount considered by the Yamana Board of Directors to be the fair value such Desert Sun for Desert Sun Shares, accompanied by a statement showing the manner in which the fair value was determined. Every Offer to Pay must be on the same terms. Yamana must pay for the Desert Sun for Desert Sun Shares of a Dissenting Shareholder within ten days after an Offer to Pay has been accepted by a Dissenting Shareholder, but any such offer lapses if Yamana does not receive an acceptance within 30 days after the Offer to Pay has been made. If Yamana fails to make an Offer to Pay for a Dissenting Shareholder's Desert Sun for Desert Sun Shares, or if a Dissenting Shareholder fails to accept an Offer to Pay which has been made, Yamana may, within 50 days after the Arrangement Effective Date or within such further period as a Court may allow, apply to a Court to fix a fair value for the Desert Sun for Desert Sun Shares of Dissenting Shareholders. If Yamana fails to apply to a Court, a Dissenting Shareholder may apply to a Court for the same purpose within a further period of 20 days or within such further period as a Court may allow. A Dissenting Shareholder is not required to give security for costs in such an application. Upon an application to a Court, all Dissenting Shareholders whose Desert Sun for Desert Sun Shares have not been purchased by Yamana will be joined as parties and bound by the decision of the Court, and Yamana will be required to notify each affected Dissenting Shareholder of the date, place and consequences of the application and of their right to appear and be heard in person or by counsel. Upon any such application to a Court, the Court may determine whether any person is a Dissenting Shareholder who should be joined as a party, and the Court will then fix a fair value for the Desert Sun for Desert Sun Shares of all Dissenting Shareholders who have not accepted an Offer to Pay. The final order of a Court will be rendered against Yamana in favour of each Dissenting Shareholder and for the amount of the fair value of their Desert Sun for Desert Sun Shares as fixed by the Court. The Court may, in its discretion, allow a reasonable rate of interest on the amount payable to each Dissenting Shareholder from the Arrangement Effective Date until the date of payment. An application to the Court by either Yamana or a Dissenting Shareholder must be in the Province of Ontario or in the province within which the Dissenting Shareholder resides if Yamana carries on business in that province. Pursuant to the Plan of Arrangement, in no case shall Yamana, Yamana Subco, Desert Sun or any other person be required to recognize any Dissenting Shareholder as Desert Sun Shareholders after the Effective Time, and the names of such Desert Sun Shareholders shall be deleted from the register of holders of Desert Sun for Desert Sun Shares at the Effective Time. Under the CBCA, the Court may make any order in respect of the Arrangement it thinks fit, including a Final Order that amends the dissent rights as provided for in the Plan of Arrangement and the Interim Order. It is not anticipated that additional Desert Sun Shareholder approval would be sought for any such variation. The foregoing is only a summary of the dissenting shareholder provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order), which are technical and complex. It is recommended that any Registered Desert Sun Shareholder wishing to avail themselves of their dissent rights under those provisions seek legal advice as failure to comply strictly with the provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order) may prejudice their dissent rights.

J-16 COMPILATION REPORT ON PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS To the Directors of Yamana Gold Inc. We have read the accompanying unaudited pro forma balance sheet of Yamana Gold Inc. ("Yamana") as at September 30, 2005 and unaudited pro forma statements of operations for the nine months then ended and for the year ended December 31, 2004, and have performed the following procedures. 1. Compared the figures in the columns captioned "Yamana Gold Inc. and Desert Sun Mining Corp." as at and for the nine months ended September 30, 2005 to the unaudited financial statements of each company as at that date and found them to be in agreement after translating Desert Sun amounts into US dollars. 2. Compared the figures in the column captioned "Yamana Gold Inc." for the ten months ended December 31, 2004 to the audited consolidated financial statements for the ten month period ended December 31, 2004 and compared the figures in the column captioned "Desert Sun Mining Corp." for the thirteen months ended December 31, 2004 to the amounts calculated by taking the amounts in the audited consolidated financial statements for the sixteen month period ended December 31, 2004 and deducting the amounts reported in the Unaudited financial statements for the three months ended November 30, 2003 (as shown in Schedule B) and found them to be in agreement after translating the Desert Sun amounts into US dollars. 3. In Schedules A-1, A-2 and A-3 compared the figures in the columns captioned "RNC Gold Inc. and Minerales Occidente S.A." to the unaudited financial statements of each company as at September 30, 2005 and for the nine months then ended, and the audited financial statements of the companies for the year ended December 31, 2004, respectively, and found them to be in agreement. 4. Made enquiries of certain officials of the company who have responsibility for financial and accounting matters about: (a) the basis for determination of the pro forma adjustments; and (b) whether the pro forma financial statements comply as to form in all material respects with Canadian standards. The officials: (a) described to us the basis for determination of the pro forma adjustments, and (b) stated that the pro forma statements comply as to form in all material respects with Canadian standards. 5. Read the notes to the pro forma consolidated financial statements and found them to be consistent with the basis described for determination of the pro forma adjustments. 6. Recalculated the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned "RNC Gold Inc., and Minerales Occidente S.A." as at September 30, 2005 and for the nine months then ended, and for the period ended December 31, 2004 and found the amounts in the column captioned "Pro Forma RNC Gold Inc." to be arithmetically correct. 7. Recalculated the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned "Yamana Gold Inc.", "RNC Gold Inc." and "Desert Sun Mining Corp.", as at September 30, 2005 and for the nine months then ended, and for the year ended December 31, 2004, and found the amounts in the column captioned "Yamana Consolidated Pro Forma." to be arithmetically correct. A pro forma financial statement is based on management assumptions and adjustments which are inherently subjective. The foregoing procedures are substantially less than either an audit or a review, the objective of which is the expression of assurance with respect to management's assumptions, the pro forma adjustments, and the application of the adjustments to the historical financial information. Accordingly, we express no such assurance. The foregoing procedures would not necessarily reveal matters of significance to the pro forma financial statements, and we therefore make no representation about the sufficiency of the procedures for the purposes of a reader of such statements.

NOTES TO THE PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS September 30, 2005 (Unaudited) (Expressed in U.S. Dollars) 1. BASIS OF PRESENTATION The unaudited pro forma consolidated financial statements have been prepared in connection with the proposed acquisition of Desert Sun Mining Corp ("Desert Sun") and RNC Gold Inc. ("RNC") by Yamana Gold Inc. ("Yamana") and concurrently the disposition of Hemco de Nicaragua S.A. ("Hemco") excluding its exploration properties. The unaudited pro forma consolidated balance sheet and the unaudited pro forma consolidated statement of operations of RNC have been prepared in connection with the acquisition of Minerales de Occidente S.A., ("Minosa") the owner of the San Andres gold mine in Honduras. In compiling the unaudited pro forma consolidated balance sheet and the pro forma consolidated statement of operations, the following historical information was used: (a) the unaudited balance sheet of Yamana as at September 30, 2005, and the unaudited statement of operations for the period from January 1, 2005 to September 30, 2005; (b) the unaudited balance sheet of Desert Sun as at September 30, 2005 and the unaudited statement of operations for the period from January 1, 2005 to September 30, 2005; (c) the unaudited balance sheet of RNC as at September 30, 2005 and the unaudited statement of operations for the period from January 1, 2005 to September 30, 2005; (d) the unaudited balance sheet of Minosa as at September 30, 2005, and the unaudited statement of operations for the period from January 1, 2005 to September 30, 2005; (e) the audited financial statements of Yamana for the ten month period ended December 31, 2004; (f) the audited financial statements of Desert Sun for the sixteen month period ended December 31, 2004; (g) the audited financial statements of RNC for the period ended December 31, 2004; and (h) the audited financial statements of Minosa for the year ended December 31, 2004. The unaudited pro forma consolidated balance sheet and the unaudited pro forma consolidated statement of operations should be read in conjunction with the September 30, 2005 and 2004 unaudited financial statements and the audited December 31, 2004 financial statements including notes thereto as listed above. The unaudited pro forma consolidated balance sheet gives effect to the proposed transactions as if they had occurred as at September 30, 2005. The unaudited pro forma consolidated statements of operations give effect to the proposed transactions as if they had occurred as at January 1, 2005 and 2004. The unaudited pro forma consolidated balance sheet and the unaudited pro forma consolidated statement of operations may not be indicative of either the financial position or the results that actually would have occurred if the events herein had been in effect on the dates indicated or the results that may be obtained in the future. The accounting policies used in the compilation are set out in Yamana's consolidated financial statements. Accounting policy differences may be identified upon consummation of the proposed acquisitions. 2. PURCHASE OF MINOSA On December 16, 2005, RNC acquired from Terra Mining Inc. ("Terra"), a private Belize company, 75% of the outstanding shares in the capital of Minosa. The consideration was the payment of $12 million and the granting of a net smelter return royalty on the production from the San Andres mine. The royalty is to be calculated as 1% on the first $20 million of annual revenue and 0.5% on all annual revenue in excess of $20 million subject to a cumulative aggregate maximum payment of $1.5 million. This royalty has been valued at $838,000 using the current mine plan, a future gold price of $400 per ounce and an 8% discount rate. Additionally, it was agreed that the loans to a local Honduran bank would be repaid ("Honduran loans"). RNC has also exercised an option to acquire all of the outstanding shares of RNC (Honduras) Limited, a Belize corporation, which is the indirect owner of the remaining 25% interest in the San Andres mine. The optioned shares to be acquired are owned by certain senior executives of RNC. The parties have agreed that the purchase price for the optioned shares will be $4 million, being the pro rata share of the cash portion of the purchase price to be received by Terra. The optionees further have agreed to accept 872,093 common shares of Yamana in satisfaction of the purchase price. These shares are to be of the same type and have the same terms as the shares issued to finance the purchase of RNC by Yamana. For purposes of the pro forma statements the acquisition is reflected in RNC with the consideration to the senior executives being a $4,000,000 note payable. If the Yamana transaction does not proceed this note would be converted to RNC shares. RNC will also acquire a 0.667% net smelter royalty on the Minosa production for consideration of $250,000. (a) Transaction adjustments The following adjustments were made to the financial statements of Minosa: (i) Accounts receivable of $2,696,594 will be distributed as a dividend in kind. (ii) Shares of RNC valued in the financial statements of Minosa at $232,391 are to be distributed to key employees of RNC prior to amalgamation with Yamana and have been expensed as a remuneration expense. (iii) The Minosa purchase price was calculated as follows: Acquisition of 75%........................................... $12,000,000 Acquisition of 25%........................................... 4,000,000 Minosa debt acquired......................................... 5,764,843 Grant of NSR royalty......................................... 838,000 Acquisition of 0.667% royalty................................ 250,000 ------- Total consideration.......................................... 22,852,843 ---------- The purchase price was allocated as follows: Net working capital acquired.................................

For the RNC unaudited pro forma balance sheet it has been recorded as an account payable and as a share issuance in the Yamana unaudited pro forma balance sheet. The entire excess purchase price over the carrying value of the assets acquired for the Minosa acquisition was allocated to mineral properties. This purchase price allocation is preliminary and will be revised on the completion of further property evaluation. (b) Financing of the Minosa acquisition In connection with the Arrangement, Yamana has entered into a credit agreement (the "Credit Agreement") with a wholly owned subsidiary ("Subco") of RNC whereby Yamana has made a senior secured loan to Subco in the amount of $18,903,000. The Loan was used to complete the purchase of 75% of the outstanding capital of Minosa and related transactions. Under the Credit agreement the loan is secured by a pledge of all of the shares of Subco and Minosa and secured by a security interest in all of the assets comprising the San Andres mine. The Loan has an interest rate of 10% and is due on March 7, 2006. In the event of a default under the Loan, including if the Arrangement is terminated or does not close on or before March 7, 2006, the loan shall be immediately due and payable in full, together with accrued and unpaid interest and Yamana may exercise an option to acquire 100% of Subco for an exercise price equal to the original principal and any accrued interest due on the Loan or enforce its rights under the Loan and the security. In the event the Arrangement is terminated as a result of a breach by Yamana, Yamana shall be precluded from exercising the option or enforcing its security for a period of 60 days. In the event of a default under the Loan, Yamana's sole recourse shall be to Subco, Minosa and the security and Yamana shall have no recourse to RNC. The proceeds of the loan were used as follows: Loan proceeds............................................... $18,903,000 ----------- The proceeds of the loan were used as follows: Acquisition of 75% of Minosa................................ 12,000,000 Acquisition of a 0.667% royalty............................. 250,000 Assets purchases............................................ 1,036,176 Debt repayments -- Minosa.................................... 5,764,843 Debt repayments -- Desminic.................................. 254,930 ------- 19,305,949 Change in cash.............................................. $(402,949) ========== 3. SALE OF HEMCO DE NICARAGUA S.A. ("HEMCO") RNC and Yamana have entered into an Arrangement Agreement ("Arrangement") pursuant to which RNC is to be amalgamated with a wholly-owned subsidiary of Yamana through a court approved plan of arrangement. As a condition to the Arrangement, Yamana is requiring RNC to dispose of Hemco and the related debt to a Management Group for proceeds of $500,000. Prior to disposition, the Company will transfer its exploration properties to a subsidiary of RNC and Yamana will assume, on a pro rata basis based on property ownership, the debt owed to Corporaciones Nationales del Sector Publico ("CORNAP") to a maximum amount of $1.5 million. The disposition of Hemco would be recorded as follows: Proceeds of disposition........................................................................................ $500,000 Excess of the fair value monetary assets over the fair value of monetary liabilities (excluding CORNAP)........ (1,373,922) Property plant and equipment, net.............................................................................. (4,048,316) CORNAP debt assigned........................................................................................... 738,102 Asset retirement obligation.................................................................................... 260,423 Loss on disposition............................................................................................ $3,923,713 ========== The Hemco land package includes a total of 205,095 hectares of exploration and exploitations concessions. Of the exploitation concessions 12,400 hectares surrounding the existing mine and mill will be sold. The 185,725 hectares of exploration concessions and 6,970 hectares of exploitation concessions will be transferred to a subsidiary of Yamana. The assigned value of the land transferred to the Yamana subsidiary is $2,720,000. As at September 30, 2005, the total outstanding CORNAP debt was $2,214,307 ($900,000 was recorded as short term portion of long term debt and $1,314,307 was recorded as long term debt). Two thirds of the debt or $1,476,205 will be retained by the Company while $738,102 will be assigned to the new owners. 4. ACQUISITION OF RNC BY YAMANA Under the Arrangement, the shareholders of RNC will receive 0.12 common shares of Yamana for each common share of RNC held. As at September 30, 2005 there were 40,569,021 shares of RNC outstanding. The volume adjusted share price of the Yamana stock for the period of two days prior to the December 4, 2005 transaction date as well as two days following the transaction date was Cdn$6.04 per share. Concurrent with the closing, Yamana has acquired all of the outstanding shares of RNC (Honduras) Limited from the optionees by the issuance of an aggregate of 872,093 common shares of Yamana. The purchase price was calculated as follows: Purchase of RNC shares RNC shares converted to Yamana shares 40,569,021 @ 0.12 = 4,868,283 Yamana shares Yamana share price of Cdn$6.04 Exchange rate of 1.16528 = US$5.18 per share Purchase of RNC shares...................................................... $25,217,705 Purchase of Minosa.......................................................... 18,903,000 Purchase of RNC (Honduras) Limited.......................................... 4,517,400 Estimated transaction expenses.............................................. 1,500,000 Fair value of options and warrants acquired................................. 1,126,080 RNC management severance.................................................... 760,000 ------- Purchase price.............................................................. 52,024,185 ---------- The purchase price was allocated as follows: Net working capital acquired................................................ (773,088) Property plant and equipment, net........................................... (28,359,691) Mineral properties and other assets......................................... (20,357,727) Long-term liabilities....................................................... 7,055,872 --------- (42,434,634) 9,589,551 Deferred tax at 25%......................................................... 3,196,517 --------- Excess of purchase price over carrying value of assets acquired............. $12,786,068 =========== The fair value of the RNC warrants which will continue with Yamana have been valued using a Black-Scholes pricing model at $826,032. The fair value of the RNC outstanding stock options have been fair valued using a Black-Scholes option pricing model at $300,048. The cost of acquisition of Minosa and the estimated cost of the Yamana and RNC Plan of Arrangement has been estimated to be $1,500,000. The entire excess purchase price over carrying value of the assets acquired was allocated to mineral properties. This purchase price allocation is preliminary and will be revised on the completion of further property evaluation. 5. ACQUISITION OF DESERT SUN BY YAMANA Under the Arrangement, the shareholders of Desert Sun will receive 0.6 common shares of Yamana for each common share of Desert Sun. As at September 30, 2005 there were 87,578,894 shares of Desert Sun outstanding. The volume adjusted share price of the Yamana stock for the period of two days prior to the February 22, 2006 transaction date as well as two days following the transaction date was $8.39 per share. The business combination will be accounted for as a purchase transaction with Yamana consolidating the results of operation of Desert Sun from the date of acquisition. Yamana will also exchange all outstanding stock options and share purchase warrants of Desert Sun for similar securities of Yamana at an exchange ratio of 0.6 and at a price equivalent to the original price divided by 0.6. Desert Sun prepares their financial statements in Canadian dollars. For the purpose of these pro forma financial statements the financial information of Desert Sun has been translated into US dollars at an exchange rate of US$0.8723 to $1 Canadian, being the closing rate on February 22, 2006, the date that the transaction was announced. The purchase price was calculated as follows: Desert Sun shares converted to Yamana shares 52,547,336 Yamana shares at $8.39 per share Purchase of Desert Sun shares............................................... $440,870,000 Estimated transaction expenses.............................................. 3,000,000 Provision for termination payments.......................................... 6,000,000 Fair value of options and warrants acquired................................. 83,900,000 ---------- Purchase price.............................................................. 533,770,000 ----------- The purchase price was allocated as follows: Net working capital acquired................................................ (10,420,000) Property plant and equipment, net........................................... (20,217,000) Mineral properties and other assets......................................... (44,274,000) Other....................................................................... 791,000 ------- (74,120,000) 459,650,000 Deferred tax at 34%......................................................... 236,800,000 ----------- Excess of purchase price over carrying value of assets acquired............. $696,450,000 ============ The fair value of the Desert Sun warrants which will continue with Yamana have been valued using a Black-Scholes pricing model at $50,700,000. The fair value of the Desert Sun outstanding stock options have been estimated using a Black-Scholes option pricing model at $33,200,000. Additionally, the pro forma purchase consideration includes the maximum liability that may arise from various management service agreements that contain termination provisions. Yamana has estimated that this obligation may generate maximum liability of approximately $6,000,000. The cost of acquisition and the estimated cost of the Yamana and Desert Sun Plan of Arrangement has been estimated to be $3,000,000. Yamana has not yet determined the fair value of all identifiable assets and liabilities acquired, the amount of the purchase price that may be allocated to goodwill, or the complete impact of applying purchase accounting to the statement of operations. Therefore, after reflecting the pro forma purchase adjustments identified to date, the excess of the purchase consideration over the adjusted book values of Desert Sun's assets and liabilities has been allocated to mineral properties. Upon consummation of the proposed acquisition of Desert Sun operations and assets, the fair value of all identifiable assets and liabilities acquired as well as any goodwill arising upon the acquisition will be determined. On completion of these assessments, with a corresponding adjustment to the historic carrying amounts of property, plant and equipment, or on the recording of any finite life intangible assets on acquisition, these adjustments will impact the measurement of amortization recorded in the consolidated statement of operations of Yamana for periods after the date of acquisition. Yamana estimates that a $100 million adjustment to the carrying value of property, plant and equipment that is in production would result in a adjustment to amortization expense in the pro forma statement of operations by approximately $3 million for the nine month period ended September 30, 2005. 6. EFFECT OF TRANSACTIONS ON THE CONSOLIDATED PRO FORMA STATEMENTS OF OPERATIONS (a) For the nine month period ended September 30, 2005 For the unaudited pro forma consolidated statements of operations to give effect to the proposed transactions as if they had occurred as at January 1, 2005 the following adjustments would be made: (i) Transaction adjustments Shares of RNC held by Minosa are to be distributed as a bonus to key employees (not to include Martin and Lough) as part of the transaction. This will result in a charge to income of $232,391. (ii) Interest expense The pro forma statement of operations for the period ended September 30, 2005 assumes that the Honduran loans would have been repaid and the Yamana loan of $18,903,000 would have been in effect. Therefore the interest expense of $510,109 accrued on the Honduran loans would not have existed however a Yamana loan interest expense of $1,417,700 would have been recorded on the financial statements of Minosa. Additionally, as the loan was from Yamana, Yamana would record an interest income of $1,417,700. Yamana would have had $18,903,000 less cash in the treasury which would have reduced the Investment and other business income by an estimated $283,500 assuming available cash could have been invested at an interest rate of 2%. (iii) Depreciation, amortization and depletion expense -- RNC It is assumed that the addition to Mineral Property related to the excess of the purchase price over the assets acquired would be amortized on a straight line basis over the life of the mine which is estimated to be 5 years. In relation to Minosa, the additional amortization for the nine month period would be calculated as $1,725,000 and for Yamana $1,917,900. (iv) Tax effect The tax effect of the mineral property amortization of the Minosa excess of purchase price over the fair value of the assets acquired calculated at 25% would be $431,250. The tax effect of the mineral property amortization of the RNC excess of purchase price over the fair value of the assets acquired calculated at 25% would be $479,500. (v) Difference in accounting policies All of the accounting policies of Yamana, Desert Sun and RNC are similar except for the policy in regards to accounting for exploration expenses. Had the Yamana exploration accounting policy been applied to RNC, $73,896 of exploration activities at Minosa would have been capitalized during the first nine months of 2005. (b) For the period ended December 31, 2004 For the unaudited pro forma consolidated statements of operations to give effect to the proposed transactions as if they had occurred as at January 1, 2004 the following adjustments would be made: (i) Transaction adjustments Shares of RNC held by Minosa are to be distributed as a bonus to key employees (not to include Martin and Lough) as part of the transaction. This will result in a charge to income of $232,391. (ii) Interest expense The unaudited pro forma statement of operations for the period ended December 31, 2004 assumes that the Honduran loans would have been repaid and the Yamana loan of $18,903,000 would have been in effect. Therefore the interest expense of $1,005,354 accrued on the Honduran loans would not have existed however an interest expense of $1,890,300 would have been recorded on the financial statements of Minosa. Additionally, as the loan was from Yamana, Yamana would record an interest income of $1,890,300. Yamana would have had $18,903,000 less cash in the treasury which would have reduced the Investment and other business income by an estimated $378,000 assuming available cash could have been invested at an interest rate of 2%. (iii) Depreciation, amortization and depletion expense -- RNC It is assumed that the addition to Mineral Property related to the excess of the purchase price over the assets acquired would be amortized on a straight line basis over the life of the properties which is estimated to be 5 years. In relation to Minosa, the additional amortization for the nine month period would be calculated as $2,300,100 and for Yamana $2,557,000. (iv) Tax effect The tax effect of the mineral property amortization of the Minosa excess of purchase price over the fair value of the assets acquired calculated at 25% would be $575,025. The tax effect of the mineral property amortization of the RNC excess of purchase price over the fair value of the assets acquired calculated at 25% would be $639,300. (v) Difference in accounting policies All of the accounting policies of Yamana, Desert Sun and RNC are similar except for the policy in regards to accounting for exploration expenses. Had the Yamana exploration accounting policy been applied to RNC, $74,503 of exploration activities at Minosa would have been capitalized during the 2004 period. 7.

YAMANA GOLD INC. By: (signed) Charles Main Chief Financial Officer EXHIBIT 5 FORM 51-102F3 MATERIAL CHANGE REPORT UNDER NATIONAL INSTRUMENT 51-102 Item 1 Name and Address of Company Yamana Gold Inc. 150 York Street, Suite 1902 Toronto, Ontario M5H 3S5 Item 2 Date of Material Change February 22, 2006 Item 3 News Release A news release with respect to the material change referred to in this report was issued by Yamana Gold Inc. and Desert Sun Mining Corp. on February 22, 2006 and subsequently filed on SEDAR. Item 4 Summary of Material Change Yamana Gold Inc. ("Yamana") and Desert Sun Mining Corp. ("DSM") announced a transaction which provides for Yamana to acquire all of the outstanding shares of DSM. Item 5 Full Description of Material Change Yamana and DSM announced a transaction which provides for Yamana to acquire all of the outstanding common shares of DSM in exchange for Yamana common shares. DSM shareholders will receive 0.6 of a Yamana common share for each DSM common share held. Based on the 5-day weighted average of Yamana's share price, the transaction price is C$5.47 per DSM common share, representing a premium of 21.1% over the 5-day weighted average price of DSM's common shares. DSM owns the long-life Jacobina gold mine in Bahia, Brazil near Yamana's Fazenda Brasileiro mine and its C1 Santa Luz pre-feasibility project. The transaction results in Yamana becoming a leading intermediate gold producer with the following profile: o Total resource base of approximately 11.6 million ounces of measured and indicated resources plus inferred resources of approximately 6.1 million ounces; o Proven and probable reserves of approximately 7.6 million gold ounces (included in above measured and indicated resource total above); -2- o Proven and probable copper reserves of approximately 2.3 billion pounds; o Cash costs projected at US$270 per ounce of gold in 2006, with US$125 and US$115 per ounce of gold projected for 2007 and 2008, respectively; and o One of the largest Brazilian exploration land holdings with a significant presence in three major gold belts. The transaction provides the following anticipated benefits to Yamana and DSM shareholders: o Creates an intermediate gold producer with one of the largest production growth profiles; o Increases operational strength and management depth; o Facilitates operational and administrative synergies; o Results in a company with further growth potential from existing development-stage assets and better positioned to take advantage of additional acquisitions; and o Broadens shareholder base and increases share liquidity. The transaction is accretive to Yamana in terms of net asset value and longer-term earnings and cash flow per share. DSM shareholders will benefit from an attractive premium and the opportunity to participate in the future growth of the combined company. SUMMARY OF THE TRANSACTION The acquisition of DSM will be completed by way of a court approved Plan of Arrangement whereby each DSM common share will be exchanged for 0.6 of a Yamana common share. All DSM options and warrants will become exercisable for common shares of Yamana based on the exchange ratio. As a result of the proposed transaction, the combined company will be held approximately 76% by existing Yamana shareholders and 24% by existing DSM shareholders. The total number of Yamana common shares outstanding would be approximately 262.1 million, on a pro forma basis after giving effect to Yamana's previously announced acquisition of RNC Gold Inc. The transaction values DSM at approximately US$500 million on a non-diluted basis. The acquisition has the unanimous approval of the boards of directors of Yamana and DSM. The board of directors of DSM, having received the unanimous recommendation of a special committee of directors, is recommending that holders of DSM common shares vote in favour of the transaction. GMP Securities L.P. provided an opinion to the special committee of the board of directors of DSM that the business combination is fair, from a financial point of view, to the holders of common shares of DSM. -3- Yamana has agreed with DSM that Bruce Humphrey (President and CEO of DSM) and Stan Bharti (Chairman of DSM) will join its board of directors. Yamana's management team may be supplemented with the addition of certain officers from DSM to whom Yamana intends to extend offers of employment. The transaction is subject to all requisite regulatory and court approvals, third party consents and other conditions customary in transactions of this nature. The combination must be approved by at least two-thirds of the votes cast by shareholders of DSM at a meeting of holders of common shares of DSM. The shareholder meeting is expected to be held on March 31, 2006, with the transaction anticipated to close shortly thereafter. If the combination does not occur under certain circumstances, DSM has agreed to pay Yamana a break-fee of C$21.5 million. Yamana's financial advisor is National Bank Financial Inc. DSM's financial advisor is Sprott Securities Inc. and its special committee of directors is being advised by GMP Securities L.P.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: This material change report uses the terms "Measured", "Indicated" and "Inferred" Resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves. United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable.

DATED at Toronto, Ontario this 20th day of March, 2006. BY ORDER OF THE BOARD OF DIRECTORS (signed) Peter Marrone President and Chief Executive Officer YAMANA GOLD INC. MANAGEMENT INFORMATION CIRCULAR Solicitation of Proxies ----------------------- This management information circular is furnished in connection with the solicitation of proxies by the management of Yamana Gold Inc. (the "Company") for use at the annual meeting of shareholders (the "Meeting") of the Company to be held at the time and place and for the purposes set forth in the accompanying Notice of Meeting. References in this management information circular to the Meeting include any adjournment or adjournments thereof. It is expected that the solicitation will be primarily by mail, however, proxies may also be solicited personally by regular employees of the Company and the Company may use the services of an outside proxy solicitation agency to solicit proxies. The cost of solicitation will be borne by the Company. The board of directors of the Company (the "Board") has fixed the close of business on March 15, 2006 as the record date, being the date for the determination of the registered holders of securities entitled to receive notice of and to vote at the Meeting. Duly completed and executed proxies must be received by the Company's transfer agent at the address indicated on the enclosed envelope no later than 4:00 p.m. (Toronto time) on April 28, 2006, or no later than 48 hours (excluding Saturdays, Sundays and holidays) before the time of any adjourned Meeting. Unless otherwise stated, the information contained in this management information circular is as of March 15, 2006. This management information circular contains references to United States dollars and Canadian dollars. All dollar amounts referenced, unless otherwise indicated, are expressed in United States dollars and Canadian dollars are referred to as "Canadian dollars" or "Cdn$". Appointment and Revocation of Proxies ------------------------------------- The persons named in the enclosed form of proxy are officers and/or directors of the Company. A shareholder desiring to appoint some other person, who need not be a shareholder, to represent him at the Meeting, may do so by inserting such person's name in the blank space provided in the enclosed form of proxy or by completing another proper form of proxy and, in either case, depositing the completed and executed proxy at the office of the Company's transfer agent indicated on the enclosed envelope no later than 4:00 p.m. (Toronto time) on April 28, 2006, or no later than 48 hours (excluding Saturdays, Sundays and holidays) before the time of any adjourned Meeting. A shareholder forwarding the enclosed proxy may indicate the manner in which the appointee is to vote with respect to any specific item by checking the appropriate space. If the shareholder giving the proxy wishes to confer a discretionary authority with respect to any item of business, then the space opposite the item is to be left blank. The shares represented by the proxy submitted by a shareholder will be voted in accordance with the directions, if any, given in the proxy. A proxy given pursuant to this solicitation may be revoked by an instrument in writing executed by a shareholder or by a shareholder's attorney authorized in writing (or, if the shareholder is a corporation, by a duly authorized officer or attorney) and deposited either at the registered office of the Company (40 King Street West, Suite 2100, Toronto, ON M5H 3C2; Attention: Mark T. Bennett, Corporate Secretary) at any time up to and including the last business day preceding the day of the Meeting or with the Chairman of the Meeting on the day of the Meeting or in any other manner permitted by law. Exercise of Discretion by Proxies --------------------------------- The persons named in the enclosed form of proxy will vote the shares in respect of which they are appointed in accordance with the direction of the shareholders appointing them. In the absence of such direction, such shares will be voted in favour of the passing of all the resolutions described below. The enclosed form of proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to matters identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting. At the time of printing of this management information circular, management knows of no such amendments, variations or other -2- matters to come before the Meeting. However, if any other matters which are not now known to management should properly come before the Meeting, the proxy will be voted on such matters in accordance with the best judgment of the named proxies. Voting by Non-Registered Shareholders ------------------------------------- Only registered shareholders of the Company or the persons they appoint as their proxies are permitted to vote at the Meeting. Most shareholders of the Company are "non-registered" shareholders ("Non-Registered Shareholders") because the shares they own are not registered in their names but are instead registered in the name of the brokerage firm, bank or trust company through which they purchased the shares. Shares beneficially owned by a Non-Registered Shareholder are registered either: (i) in the name of an intermediary (an "Intermediary") that the Non-Registered Shareholder deals with in respect of the shares of the Company (Intermediaries include, among others, banks, trust companies, securities dealers or brokers and trustees or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans); or (ii) in the name of a clearing agency (such as The Canadian Depository for Securities Limited) of which the Intermediary is a participant. In accordance with applicable securities law requirements, the Company will have distributed copies of the Notice of Meeting, this management information circular, the form of proxy and the supplemental mailing list return card (collectively, the "Meeting Materials") to the clearing agencies and Intermediaries for distribution to Non-Registered Shareholders. Intermediaries are required to forward the Meeting Materials to Non-Registered Shareholders unless a Non-Registered Shareholder has waived the right to receive them. Intermediaries often use service companies to forward the Meeting Materials to Non-Registered Shareholders. Generally, Non-Registered Shareholders who have not waived the right to receive Meeting Materials will either: (i) be given a voting instruction form which is not signed by the Intermediary and which, when properly completed and signed by the Non-Registered Shareholder and returned to the Intermediary or its service company, will constitute voting instructions (often called a "voting instruction form") which the Intermediary must follow. Typically, the voting instruction form will consist of a one page pre-printed form. Sometimes, instead of the one page pre-printed form, the voting instruction form will consist of a regular printed proxy form accompanied by a page of instructions which contains a removable label with a bar-code and other information. In order for the form of proxy to validly constitute a voting instruction form, the Non-Registered Shareholder must remove the label from the instructions and affix it to the form of proxy, properly complete and sign the form of proxy and submit it to the Intermediary or its service company in accordance with the instructions of the Intermediary or its service company; or (ii) be given a form of proxy which has already been signed by the Intermediary (typically by a facsimile, stamped signature), which is restricted as to the number of shares beneficially owned by the Non-Registered Shareholder but which is otherwise not completed by the Intermediary. Because the Intermediary has already signed the form of proxy, this form of proxy is not required to be signed by the Non-Registered Shareholder when submitting the proxy. In this case, the Non-Registered Shareholder who wishes to submit a proxy should properly complete the form of proxy and deposit it with the Company, c/o CIBC Mellon Trust Company, 320 Bay Street, Toronto, Ontario, M5H 4A6. In either case, the purpose of these procedures is to permit Non-Registered Shareholders to direct the voting of the shares of the Company they beneficially own. Should a Non-Registered Shareholder who receives one of the above forms wish to vote at the Meeting in person (or have another person attend and vote on behalf of the Non-Registered Shareholder), the Non-Registered Shareholder should strike out the persons named in the form of proxy and insert the Non-Registered Shareholder or such other person's name in the blank space provided. In either case, Non-Registered Shareholders should carefully follow the instructions of their Intermediary, including those regarding when and where the proxy or voting instruction form is to be delivered. A Non-Registered Shareholder may revoke a voting instruction form or a waiver of the right to receive Meeting Materials and to vote which has been given to an Intermediary at any time by written notice to the Intermediary provided that an Intermediary is not required to act on a revocation of a voting instruction form or of a waiver of the right to receive Meeting Materials and to vote which is not received by the Intermediary at least seven (7) days prior to the Meeting. -3- Interest of Certain Persons in Matters to be Acted Upon ------------------------------------------------------- No (a) director or executive officer of the Company who has held such position at any time since January 1, 2005; (b) proposed nominee for election as a director of the Company; or (c) associate or affiliate of a person in (a) or (b) has any material interest, direct or indirect, by way of beneficial ownership of securities or otherwise, in any matter to be acted upon at the Meeting. Voting Securities and Principal Holders Thereof ----------------------------------------------- As of March 20, 2006, 199,403,427 common shares (the "Common Shares") in the capital of the Company were issued and outstanding. Each Common Share entitles the holder thereof to one vote on all matters to be acted upon at the Meeting. The record date for the determination of shareholders entitled to receive notice of and to vote at the Meeting has been fixed at March 15, 2006. In accordance with the provisions of the Canada Business Corporations Act (the "CBCA"), the Company will prepare a list of holders of Common Shares as of such record date. Each holder of Common Shares named in the list will be entitled to vote the shares shown opposite his or her name on the list at the Meeting. All such holders of record of Common Shares are entitled either to attend and vote thereat in person the Common Shares held by them or, provided a completed and executed proxy shall have been delivered to the Company's transfer agent within the time specified in the attached Notice of Meeting, to attend and vote thereat by proxy the Common Shares held by them. To the knowledge of the directors and executive officers of the Company, as of the date hereof, the only persons, or companies who beneficially own, directly or indirectly, or exercise control or direction over voting securities of the Company carrying more than 10% of the voting rights attached to any class of voting securities of the Company are as follows: Number of Percentage of Name Common Shares Outstanding Common Shares ---- ------------- ------------------------- Santa Elina Mines Corporation(1) 33,546,134 17% (1) Juvenal Mesquita, a director of the Company, is a director of Santa Elina Mines Corporation.

During the financial year ended December 31, 2005, Victor Bradley was paid $25,000 to Chair a special committee and each of James Askew, Patrick Mars, and Lance Tigert was paid Cdn $20,000 for serving on a special committee.

The aggregate limit on liability for directors and officers under the insurance policy is $10 million, and the aggregate premium paid by the Company is $140,000. The terms of the policy provide for a deductible of $250,000 in respect of securities law claims and $100,000 in respect of all other claims. Composition of the Compensation Committee ----------------------------------------- During 2005, the Compensation Committee was comprised of James Askew (Chairman), Lance Tigert (to March 2005) and Peter Marrone (non-voting, ex officio member). In January 2006, the Compensation Committee was re-constituted and is currently compromised of Nigel Lees (Chairman), Victor Bradley and Dino Titaro. -9- Report on Executive Compensation -------------------------------- Overall Compensation Philosophy The following principles guide the Company's overall compensation philosophy: (a) compensation is determined on an individual basis by the need to attract and retain talented, high-achievers; (b) calculating total compensation is set with reference to the market for similar jobs in similar locations; (c) an appropriate portion of total compensation is variable and linked to achievements, both individual and corporate; (d) internal equity is maintained such that individuals in similar jobs and locations are treated fairly; and (e) the Company supports reasonable expenses in order that employees continuously maintain and enhance their skills. Compensation Committee Mandate The Compensation Committee is established by the Board to assist the Board in fulfilling its responsibilities relating to human resources and compensation issues and to establish a plan of continuity for executive officers and other members of senior management (collectively, "Executive Management"). The Compensation Committee ensures that the Company has an executive compensation plan that is both motivational and competitive so that it will attract, hold and inspire performance of Executive Management of a quality and nature that will enhance the sustainable profitability and growth of the Company. The Compensation Committee reviews and recommends the compensation philosophy and guidelines for the Company which include reviewing the compensation philosophy and guidelines (a) for Executive Management, for recommendation to the Board for its consideration and approval, and (b) relating to all employees, including annual salary and incentive policies and programs, and material new benefit programs, or material changes to existing benefit programs. The Compensation Committee reviews on an annual basis the cash compensation, performance and overall compensation package for each executive officer. It then submits to the Board recommendations with respect to the basic salary, bonus and participation in share compensation arrangements for each executive officer. Following discussions with management of the Company and receiving recommendations from management for 2005 bonuses and 2006 salaries for Executive Management and employees of the Company, the Compensation Committee made its recommendations to the Board for approval in December 2005. In conducting its review of management's recommendations, the Compensation Committee was satisfied that all recommendations complied with the Compensation Committee's philosophy and guidelines set forth above. Base Salary In determining the base salary of an executive officer, the Compensation Committee places equal weight on the following factors: (a) the particular responsibilities related to the position; (b) salaries paid by comparable businesses; (c) the experience level of the executive officer; and (d) his or her overall performance. -10- Bonus Payments Executive officers are eligible for annual cash bonuses, after taking into account and giving equal weight to, financial performance, attainment of certain corporate objectives and individual performance. In taking into account the financial performance aspect, it is recognized that executive officers cannot control certain factors, such as currency exchange rates, commodity prices and interest rates. When applying the financial performance criteria, the Compensation Committee considers factors over which the executive officers can exercise control, such as meeting budget targets established by the Board at the beginning of each year, controlling costs, taking successful advantage of business opportunities and enhancing the competitive and business prospects of the Company. There are no pre-established payout ranges. During the financial year ended December 31, 2005, bonuses were awarded to the following Named Executive Officers of the Company: Peter Marrone, President and Chief Executive Officer, in the amount of Cdn$500,000; Charles Main, Vice President, Finance and Chief Financial Officer, in the amount of Cdn$125,000; Antenor Silva, Chief Operations Officer, in the amount of $139,320, and Greg McKnight, Vice President, Business Development, in the amount of Cdn$125,000. Long-Term Incentives It is the compensation philosophy of the Company to emphasize the equity incentive portion of compensation. Accordingly, base salaries and bonuses have been at the relatively low end of the scale compared to industry peers with a greater emphasis placed on options. The Company believes that weighting compensation to options better aligns the interests of management with the interests of its shareholders. During the financial year ended December 31, 2005, the Board, on the recommendation of the Compensation Committee, granted stock options to Named Executive Officers of the Company as follows: Name of Officer Title of Officer Number of Options --------------- ---------------- ----------------- Peter Marrone President and Chief Executive Officer 600,000 Charles Main Vice President, Finance and Chief Financial Officer 200,000 Antenor Silva Chief Operations Officer 400,000 Greg McKnight Vice President, Business Development 200,000 All of these options were granted at an exercise price of Cdn$3.69 for a term of ten years, and vested immediately upon grant. The exercise price of the options was determined based on closing price of the Common Shares on the TSX on May 12, 2005, the date before the grant in accordance with the terms of the Share Incentive Plan. Chief Executive Officer Compensation The components of the Chief Executive Officer's compensation are the same as those which apply to the other senior executive officers of the Company, namely base salary, bonus and long-term incentives in the form of stock options. The Chairman of the Compensation Committee presents recommendations of the Compensation Committee to the Board with respect to the Chief Executive Officer's compensation. In setting the Chief Executive Officer's salary, the Compensation Committee reviews salaries paid to other senior officers in the Company, salaries paid to other chief executive officers in the industry and the Chief Executive Officer's impact on the achievement of the Company's objectives for the previous financial year, as measured against his key performance indicators. During the financial year ended December 31, 2005, Mr. Marrone's base salary was Cdn$501,960 and he was granted a cash bonus of Cdn$500,000 in recognition of his contribution to the development of the Company. During the financial year ended December 31, 2005, Mr. Marrone was also granted options to purchase 600,000 Common Shares under the Share Incentive Plan (see "Option Grants During the Financial Year Ended December 31, 2005" table above for further details). -11- The foregoing report has been submitted by the Compensation Committee: Nigel Lees (Chairman) Victor Bradley Dino Titaro Performance Graph The following graph compares the yearly percentage change in the cumulative total shareholder return for Cdn$100 invested in Common Shares on August 1, 2003 against the cumulative total shareholder return of the S&P/TSX Composite Index and the S&P/TSX Composite Index Gold for the three most recently completed financial years of the Company following the completion of its reverse take-over transaction in August 2003, assuming the reinvestment of all dividends.

(3) An additional 8,510,000 Common Shares are to be issued upon the exercise of stock options that were granted under the amended share incentive plan to certain officers, directors and employees of the Company on March 23, 2006, which stock options are only exercisable subject to the ratification of the grant thereof by the shareholders at the Meeting, pursuant to the rules of the TSX. See "Security Based Compensation Arrangements" and "Ratification of Stock Option Grants". Security Based Compensation Arrangements ---------------------------------------- Share Incentive Plan The Company's share incentive plan (the "Share Incentive Plan") dated June 24, 2004, as amended, is designed to advance the interests of the Company by encouraging eligible participants, being employees, officers, directors and consultants, to have equity participation in the Company through the acquisition of Common Shares. The current aggregate maximum number of Common Shares that may be reserved for issuance under stock options granted pursuant to the Share Incentive Plan is 9,500,000, representing approximately 5% of Company's issued and outstanding Common Shares as at March 20, 2006. Options to purchase an aggregate of 7,953,765 Common Shares, representing approximately 4% of the Company's issued and outstanding Common Shares as at March 20, 2006, are currently outstanding and exercisable under the Share Incentive Plan. In connection with the acquisition of RNC Gold Inc., the Company assumed options (the "RNC Options") outstanding under the RNC Gold Inc. stock option plan exercisable to acquire an aggregate of 375,720 Common Shares. In connection with the proposed acquisition of Desert Sun Mining Corp., the Company has agreed to assume options (the "DSM Options") outstanding under the Desert Sun Mining Corp. stock option plan exercisable into 5,128,298 Common Shares. The RNC Options and DSM Options are not governed by or outstanding under the Share Incentive Plan. However, for the purposes of calculating the number of Common Shares available to be issued upon the exercise of options granted under the Share Incentive Plan following the approval of the amendment to the Share Incentive Plan described herein, any Common Shares reserved for issuance upon the exercise of then outstanding RNC Options and DSM Options shall be deducted from the number of Common Shares otherwise issuable under the Share Incentive Plan. The Share Incentive Plan provides for an aggregate maximum reserve of 5% of the Company's issued and outstanding Common Shares for issuance to any one person. The Share Incentive Plan does not include a limit on the number of Common Shares issuable to insiders, however, as described below, the Company proposes to amend the Share Incentive Plan to add such restriction. Options granted under the Share Incentive Plan have an exercise price of not less than the closing price of the Common Shares on the TSX on the trading day immediately preceding the date on which the option is granted and are exercisable for a period not to exceed ten years. The vesting of stock options is at the discretion of the Board of Directors of the Company, and there are currently no vesting provisions governing any of the outstanding stock options. Options granted under the stock option component are not transferable or assignable and terminate: (i) within a period of 60 days following the termination of an optionee's employment, subject to any agreement with a director or officer of the Company with respect to the rights of such director or officer upon termination or a change of control of the Company; and (ii) within a period of six months following the death of an optionee. -13- The Share Incentive Plan also provides for the granting of stock appreciation rights to optionees. An optionee is entitled to elect to terminate his or her option, in whole or part, and, in lieu of receiving the Common Shares to which the terminated option relates, to receive that number of Common Shares, disregarding fractions, which, when multiplied by the fair value of the Common Shares (which is the average closing price of the Common Shares on the TSX for the five trading days prior to the date of termination of the option) to which the terminated option relates, has a total value equal to the product of the number of such Common Shares times the difference between the fair value and the option price per share of such Common Shares, less any amount required to be withheld on account of income taxes. During the year ended December 31, 2005, a total of 347,175 Common Shares were issued upon the exercise of outstanding stock appreciation rights. The Board and/or the Compensation Committee of the Board, may modify or terminate the Share Incentive Plan at any time. However, any amendment of the Share Incentive Plan which would: (a) materially increase the benefits under the plan; (b) increase the number of Common Shares which may be issued under the plan; or (c) materially modify the requirements as to the eligibility for participation in the plan is subject to the approval of the shareholders of the Company. Any amendment to any provision of the Share Incentive Plan is subject to receipt of any necessary approvals by any stock exchange or regulatory body having jurisdiction over the securities of the Company. The Company does not provide any financial assistance to Participants under the Share Incentive Plan to facilitate the purchase of securities under the Share Incentive Plan. At the Meeting, shareholders are being asked to consider and, if thought appropriate, to pass a resolution to amend the Share Incentive Plan to (i) increase the maximum number of Common Shares that may be reserved for issuance upon exercise of options granted under the Share Incentive Plan by 15,400,000 Common Shares or in the event that the proposed acquisition of Desert Sun Mining Corp. is not completed by 9,800,000 Common Shares; (ii) add a limitation on the percentage of securities issuable to insiders under all security based compensation arrangements; and (iii) amend the provisions concerning amendments and modifications to the Share Incentive Plan. For the purposes of calculating the number of Common Shares reserved for issuance upon exercise of options granted under the Share Incentive Plan, the Company includes Common Shares reserved for issuance upon the exercise of DSM Options and RNC Options. See "Approval of Amendment to Share Incentive Plan". The effect of the amendment to increase the maximum number of Common Shares reserved for issuance under the Share Incentive Plan will be to provide that the number of Common Shares reserved for issue upon the exercise of the following shall not exceed approximately 9% of the outstanding Common Shares: (i) options currently outstanding under the Share Incentive Plan, (ii) options available for grant under the Share Incentive Plan, (iii) outstanding RNC Options and (iv) in the event that the acquisition of Desert Sun Mining Corp. is completed, outstanding DSM Options. On a fully-diluted basis, the number of common Shares reserved for issue shall not exceed 8% in the event that the acquisition if Desert Sun Mining Corp. is completed or 8.4% in the event that the proposed acquisition in not completed. In 2006, the Compensation Committee approved the grant of an aggregate of 8,510,000 stock options to certain non-executive directors, officers, employees and consultants of the Company, as set out below. These options were granted on March 23, 2006 following the expiry of the trading black-out relating to the dissemination of the Company's annual financial statements. These options were, in part, granted based on the contribution of the optionees to the growth of the Company, including the completed acquisition of RNC Gold Inc. and the proposed acquisition of Desert Sun Mining Corp. In addition, during the past 12 months, the Company's capital structure was simplified by the early exercise of publicly-traded common share purchase warrants and the Company completed the Sao Francisco mine, accelerated completion of the Chapada copper-gold project and executed its business plan including the strategic plan announced in October 2005. These contributions have significantly advanced the development of the Company to the status of an intermediate gold producer. -14- Category of Grantee Number of Options Exercise Price Expiry Date ------------------- ----------------- -------------- ----------- Non-Executive Directors 1,500,000 Cdn$9.65 March 22, 2011 Named Executive Officers 3,700,000 Cdn$9.65 March 22, 2011 Employees 2,700,000 Cdn$9.65 March 22, 2011 Consultants 610,000 Cdn$9.65 March 22, 2011 The exercise price of the stock options was the closing price of the Common Shares on the TSX on the trading day immediately preceding the date of grant. The above-noted stock options can only be exercised upon the approval by the shareholders at the Meeting of the proposed amendments to the Share Incentive Plan, which include an increase in the maximum number of shares reserved for issuance upon the exercise of stock options granted under the Share Incentive Plan in accordance with the rules of the TSX. Further, the exercise of the Options is subject to the completion of the acquisition of Desert Sun Mining Corp. The aggregate amount of the above-noted option grants represent less than 3.2% of issued and outstanding Common Shares after giving effect to the acquisition of Desert Sun Mining Corp. (and less than 2.9% on a fully diluted basis after giving effect to such acquisition). The grant to any one officer or employee is less than 1% of the issued and outstanding Common Shares after giving effect to the acquisition of Desert Sun Mining Corp. The grant to non-executive directors as a group is less than 1% of the issued and outstanding Common Shares as of the date of grant and less than 1% of the issued and outstanding Common Shares after giving effect to the acquisition of Desert Sun Mining Corp. When the above-noted grants are combined with all other outstanding stock options currently held by officers and employees, no one officer or employee will hold options exercisable for more than 1.4% of the issued and outstanding Common Shares after giving effect to the acquisition of Desert Sun Mining Corp. (and no more than 1.3% on a fully diluted basis after giving effect to such acquisition). Other Security Based Compensation Arrangements The Company proposes to issue to its officers and employees an aggregate of up to 300,000 Common Shares, representing approximately 0.15% of the issued and outstanding Common Shares as at March 20, 2006, as security based compensation to such persons for contributions to the Company based on the compensation philosophy, guidelines and key performance indicators established by the Compensation Committee. The Compensation Committee has determined to award such additional equity compensation to provide a mechanism to award performance based compensation which does not involve the use of cash resources. The number of Common Shares to be issued to one officer, insider or employee shall not exceed 75,000 Common Shares, or 0.04 % of the Common Shares outstanding at the time of grant (on a non-diluted basis). The purchase price allocated to the Common Shares will not be less than the market price of the Common Shares as at the time of grant, as market price is defined under the rules of the TSX. The Common Shares, if issued, cannot be sold for a period of 12 months from the date of issue. At the Meeting, shareholders are being asked to pass a resolution approving these security based compensation arrangements. See "Approval of Security Based Compensation Arrangement". Corporate Governance Practices ------------------------------ National Policy 58-201 entitled "Corporate Governance Guidelines" ("NP 58-201") sets out guidelines for effective corporate governance. These guidelines deal with matters such as the constitution and independence of corporate boards, their functions, the effectiveness and education of board members and other items dealing with sound corporate governance. National Instrument 58-101 entitled "Disclosure of Corporate Governance Practices" ("NI 58-101") requires that if management of an issuer solicits proxies from its securityholders for the purpose of electing directors, specified disclosure of the corporate governance practices must be included in its management information circular. The Company and the Board recognize the importance of corporate governance to the effective management of the Company and to the protection of its employees and shareholders. The Company's approach to significant issues of corporate governance is designed with a view to ensuring that the business and affairs of the Company are effectively managed so as to enhance shareholder value. The -15- Board of Directors fulfills its mandate directly and through its committees at regularly scheduled meetings or as required. Frequency of meetings may be increased and the nature of the agenda items may be changed depending upon the state of the Company's affairs and in light of opportunities or risks which the Company faces. The directors are kept informed of the Company's operations at these meetings as well as through reports and discussions with management on matters within their particular areas of expertise. The Company's corporate governance practices have been and continue to be in compliance with applicable Canadian and United States requirements. The Company continues to monitor developments in Canada and the United States with a view to further revising its governance policies and practices, as appropriate. The Board of Directors has considered the guidelines set out in NP 58-201 and believes that its approach to corporate governance is appropriate and works effectively for the Company and its shareholders. The following is a description of the Company's corporate governance practices which has been prepared by the Corporate Governance and Nominating Committee of the Board and has been approved by the Board. The Board of Directors The Board of Directors is currently comprised of Victory Bradley (Chair), Peter Marrone, James Askew, Nigel Lees, Patrick Mars, Juvenal Mesquita, Antenor Silva and Dino Titaro. The majority of the members of the Company's Board of Directors, including the Chair of the Board of Directors, are independent within the meaning of NI 58-101 and hold regularly scheduled meetings. Messrs. Marrone and Silva are not independent as they are the President and Chief Executive Officer of the Company and the Chief Operating Officer of the Company, respectively. Mr. Mesquita is also not independent as he is a consultant to the Company. Although Mr. Bradley acted as President and Chief Executive Officer of the Company until July 31, 2003, the Board of Directors does not consider Mr. Bradley to have a material relationship with the Company which could be reasonably expected to interfere with the exercise of his independent judgement as a non-executive director of the Company, and considers Mr. Bradley to be independent. Each of Messrs. Askew, Lees, Mars and Titaro is independent. In connection with the proposed acquisition of Desert Sun Mining Corp., the Company has agreed to appoint Stan Bharti, Chairman of Desert Sun Mining Corp. and Bruce Humphrey, President and Chief Executive Officer of Desert Sun Mining Corp. to the Board of Directors on the closing of the acquisition, scheduled for early April 2005. In addition, Mr. Askew is not standing for re-election as a director. The role of the Company's Chairman of the Board is to chair all meetings of the Board in a manner that promotes meaningful discussion, and to provide leadership to the Board to enhance the Board's effectiveness in meeting its responsibilities. The Chairman's responsibilities include, without limitation, ensuring that the Board of Directors works together as a cohesive team with open communication; working together with the Corporate Governance and Nominating Committee to ensure that a process is in place by which the effectiveness of the Board, its committees and its individual directors can be evaluated on at least an annual basis. The Chairman also acts as a liason between the Board and management to ensure that the relationship between the Board and management is professional and constructive and ensures that the allocation of responsibilities and the boundaries between Board and management are clearly understood. The independent directors meet regularly without management to review the business operations, corporate governance and financial results of the Company. During the fiscal year ended December 31, 2005, the Board of Directors held 12 meetings. The attendance of each of the directors, based on the number of meeting each was eligible to attend is as follows: Mr. Marrone (12/12), Mr. Bradley (12/12), Mr. Askew (7/12), Mr. Mars (12/12), Mr. Mesquita (11/12), Mr. Silva (9/12), Mr. Lees (8/8) and Mr. Titaro (6/6). Mr. Lees joined the board on June 16, 2005 and Mr. Titaro joined the board on August 5, 2005. Messrs. Bradley, Askew, Lees, Mars Titaro, Marrone, Mesquita and Silva are current directors of the other reporting issuers set forth below: -16- Director Name Directorships with Other Reporting Issuers ------------- ------------------------------------------ Victor H.

Appointment of Auditors ----------------------- Unless authority to do so is withheld, the persons named in the accompanying proxy intend to vote for the appointment of Deloitte & Touche LLP, Chartered Accountants, as auditors of the Company until the close of the next annual meeting of shareholders and to authorize the directors to fix their remuneration. Deloitte & Touche LLP, Chartered Accountants, were first appointed as auditors of the Company since its incorporation in 1995. Approval of Amendment to Share Incentive Plan --------------------------------------------- The Company is engaged in the acquisition, exploration, development and operation of mineral projects. The ability of the Company to acquire, explore and develop mineral projects is dependent upon having sufficient financing and cash flow from its operating mines to fund such activities. The Company is also actively pursuing growth opportunities involving mineral exploration, development or production assets which may require additional financing and as a result, the Company's compensation philosophy is to emphasize the equity position of compensation as compared to base salaries and bonuses payable in cash. The Company believes that its base salary and cash bonus compensation is at the low end of the scale compared to its peers. The Company also believes that weighting compensation to options better aligns the interests of management with the interests of shareholders and is consistent with the Company's growth strategy. Accordingly, the shareholders are being asked to authorize and approve a resolution authorizing an amendment to the Share Incentive Plan to (i) increase the maximum number of Common Shares that may be reserved for issuance upon exercise of options granted thereunder by 15,400,000 Common Shares or -23- if the acquisition of Desert Sun Mining Corp. is not completed, by 9,800,000 Common Shares; (ii) add a limitation on the percentage of securities issuable to insiders under all security based compensation arrangements; and (iii) amend the provisions concerning amendments and modifications to the Share Incentive Plan. For the purposes of calculating the number of Common Shares reserved for issuance upon exercise of options granted under the Share Incentive Plan, the Company includes Common Shares reserved for issuance upon the exercise of DSM Options and RNC Options. The effect of the amendment to increase the maximum number of Common Shares reserved for issuance under the Share Incentive Plan will be to provide that the number of Common Shares reserved for issue upon the exercise of the following shall not exceed approximately 9% of the outstanding Common Shares: (i) options currently outstanding under the Share Incentive Plan, (ii) options available for grant under the Share Incentive Plan, (iii) outstanding RNC Options and (iv) in the event that the acquisition of Desert Sun Mining Corp. is completed, outstanding DSM Options. On a fully-diluted basis, the number of common Shares reserved for issue shall not exceed 8% in the event that the acquisition if Desert Sun Mining Corp. is completed or 8.4% in the event that the proposed acquisition in not completed. Management of the Company believes that the proportion of the number of Common Shares issuable under the Share Option Plan relative to the number of issued and outstanding Common Shares is within a competitive range in its industry. Other than as described herein, all other provisions of the Share Option Plan will remain in full force and effect. The Board has approved the amendment to the Share Option Plan, subject to shareholder and stock exchange approvals. See "Security Based Compensation Arrangements - Share Incentive Plan". The Board recommends that shareholders vote for the adoption of the resolution. In order to be effective, the resolution must be approved by the affirmative vote of a majority of the votes cast at the Meeting in respect of such resolution. Unless otherwise indicated, the persons named in the accompanying proxy intend to vote for the resolution with respect to the amendment of the Share Incentive Plan on any ballot requested or required by law.

The Compensation Committee has determined to award such additional equity compensation to provide a mechanism to award performance based compensation which does not involve the use of cash resources. The number of Common Shares to be issued to one officer, insider or employee shall not exceed 75,000 Common Shares, or 0.04 % of the Common Shares outstanding at the time of grant (on a non-diluted basis). The purchase price allocated to the Common Shares will not be less than the market price of the Common Shares as at the time of grant, as market price is defined under the rules of the TSX. The Common Shares, if issued, cannot be sold for a period of 12 months from the date of issue. The Board has approved the Common Share issuance, subject to shareholder and stock exchange approvals.
