IAMGOLD Announces Results of Côté Gold Project Update

By: Newsfile

Toronto, Ontario--(Newsfile Corp. - August 3, 2022) - IAMGOLD Corporation (NYSE: IAG) (TSX: IMG) ("IAMGOLD" or the "Company") today announced its updated estimate of costs to complete, project economics and life-of-mine ("LOM") plan for the Côté Gold project ("Côté Gold" or the "Project") in Ontario, Canada. A NI 43-101 technical report will be filed on SEDAR on or before September 17, 2022. The project update concludes the Côté Gold costs, schedule, execution strategy and risk review ("project review and risk analysis") initiated by the Company earlier this year. All dollar amounts are expressed in United States dollars, unless otherwise indicated.

Highlights of the Côté Gold 2022 Technical Report:

  • After-tax net present value at a 5% discount rate ("NPV5%") of $1,109 million on a 100% basis, and an internal rate of return ("IRR") of 13.5% - at a gold price assumption of $1,700 in 2024 and 2025 and $1,600 thereafter and CAD:USD exchange rate of 1.25 (from May 1, 2022);

  • Estimated remaining project costs to complete construction and bring Côté Gold into production of $1,908 million ($1,335 million attributable to IAMGOLD) including escalation and contingency as of May 1, 2022;

  • Mine life of 18 years with initial production expected in early 2024;

  • Average annual production of 495,000 ounces (320,500 ounces attributable) during the first six years following commercial production, and 365,000 ounces (236,000 ounces attributable) over the LOM;

  • LOM average cash costs of $693 per ounce gold ("/oz Au") sold and all-in sustaining costs ("AISC") of $854/oz Au sold;

  • Cumulative net operating cash flow of $6,086 million and after-tax free cash flow of $2,597 million;

  • Côté Gold LOM plan based on Mineral Reserves of 7.2 million ounces in the Côté deposit;

  • Côté deposit Measured & Indicated Mineral Resource estimate (inclusive of Mineral Reserves) of 10.2 million ounces; Gosselin deposit Measured & Indicated Resource estimate of 3.4 million ounces; and

  • District scale potential with demonstrated exploration upside in one of the world's leading mining jurisdictions.

Maryse Bélanger, Chair of the Board and Interim President and CEO, said: "The completion of the Côté Gold project review, risk analysis and updated mine plan is the culmination of months of in-depth analysis of the project, based on first principles, by the Company's management and project teams, EPCM contractor and technical experts. The project today is over 57% complete and the updated project costs and schedule give us greatly improved visibility towards completion. Côté Gold is a project that is being advanced in an environment with significant headwinds, including COVID-19, inflation and other global events - and their impacts on global supply chains, labour availability, and the associated costs of doing business. We are very proud of our teams as they navigate these challenges to continue to advance the project for the benefit of our partners, stakeholders and our business.

"Côté Gold is transformational for IAMGOLD. Once in production, the Project is projected to offer robust free cash flow generation, averaging 365,000 ounces per year at AISC of $854 per ounce for 18 years, based on the 7.2 million ounces currently estimated in Mineral Reserves. There is also tremendous potential for future expansion, starting with the Gosselin deposit, located immediately adjacent to the Côté pit containing 3.4 million ounces in Indicated Mineral Resource and an additional 1.7 million ounces in Inferred Resources. Gosselin has only been drilled to half the depth of Côté and remains open along strike. We believe that Côté Gold is not just a project, but the start of a district, with minimal historical exploration targeting Côté/Gosselin style intrusion-hosted deposits within our 596 km2 land package.

"Given the importance of Côté Gold to achieve our goal of becoming a leading high-margin gold producer, we are actively pursuing various alternatives to increase liquidity to complete construction and deliver Côté on the updated schedule. We expect to address these near-term challenges to advance Côté and better position IAMGOLD as a more resilient, agile company for the current environment."

Notes:

  1. Measured Mineral Resources and Indicated Mineral Resources that are not Mineral Reserves are considered uneconomic at the price used for Mineral Reserve estimations but are deemed to have a reasonable prospect of economic extraction.
  2. The effective date of the Mineral Reserves estimate is May 1, 2022.
  3. The Mineral Reserves were estimated assuming open pit mining methods and are reported on a 100% Project basis.
  4. Mineral Reserves used the following assumptions: price of $1,200/oz Au; fixed process recovery of 91.8%; treatment and refining costs, including transport and selling costs of $1.75/oz Au; variable royalty percentages by zone: 0.75% for Zone 1, 1.00% for zone 2, 0.00% for zone 3, 1.50% for zone 4, 0.75% for zone 5, 1.50% for zone 6, and 0.75% for zones 7 and 8; overall pit slope angles varying by sector with a range of 45.8° to 56.4°; processing costs of $10.17/t, which includes process operating costs of $7.01/t, general and administrative costs of $1.84/t, sustaining costs of $0.82/t, and closure costs of $0.50/t; mining costs of $1.61/t incremented at $0.029/t/12m below 388 elevation (life-of-mine average mining costs of $2.01/t); and rehandling costs of $0.87/t. The cut-off applied to the reserves is 0.35 g/t Au.
  5. Numbers have been rounded. Totals may not sum due to rounding.

Pit optimization parameters, financial assumptions, pit-shell selection, and mining dilution and recovery factors remain unchanged from the 2018 feasibility study technical report. The mine design was updated to optimize pit phasing, ramp location, and waste stripping, resulting in negligible changes to Mineral Reserves compared to the previous estimate, and small reductions in waste.

Mine Design and Mining Methods

The mine will operate a fleet of autonomous trucks and blasthole drills, supported by a conventional fleet for loading and ancillary equipment. The truck fleet is diesel-powered and provides enough capacity to mine an average of approximately 54 Mtpa, with a peak of 70 Mtpa by the addition of five haul trucks by year 8. The loading fleet will include two electric-powered hydraulic shovels, supplemented by three large diesel-powered front-end loaders (FELs). Primary mobile equipment will consist of:

  • Loading - CAT 6060 electric/hydraulic (6060E) shovel and CAT 994K high lift FELs
  • Hauling - CAT 793F mechanical drive truck operated in autonomous mode

Pre-production commenced with contract mining in the first quarter 2021 and consists of overburden removal, construction material supply, and initial bench development. Contractor mining will phase out in the first quarter 2023 towards a handoff to owner mining in the second quarter 2023. In parallel, delivery of autonomous equipment has begun in the second quarter of 2022 and owner mining is expected to commence in the first quarter of 2023. The mine is scheduled to operate 24 hours per day, seven days per week (24/7 schedule), using four rotating crews working 12 hour shifts.

The Côté pit design has been updated to be mined in five phases. The scheduling constraints establish the maximum mining capacity at 70 Mtpa and the maximum number of benches mined per year at eight in each phase. The design parameters include a ramp width of 36 m, maximum road grades of 10%, bench height of 12 m, berm height interval of 24 m, geotechnical catch bench of 20 m if stacking height is greater than 150 m, a minimum mining width of 40 m, and variable slope angles and berm widths by sector.

The final pit design contains 235 Mt of ore at 0.95 g/t Au and 575 Mt of waste for a resulting stripping ratio of 2.4:1 (waste:ore). The total LOM mill feed is 233 Mt at 0.96 g/t Au, constrained by the TMF capacity, and 2.3 Mt of low grade ore material remaining in stockpiles at the end of mine life.

The updated mine plan in the 2022 Technical Report has made the following changes in assumptions in mine design and mining from the 2021 Technical Report:

  • Revised pit phasing incorporating a Phase 1 Pit design centered on a higher-grade zone and re-phasing of Phases 2-4;
  • Steeper ramp gradient in Phase 1 (10% versus 8% previously) allowing to reach an additional bench at the bottom of the Phase 1 pit;
  • Modification to starter pit boundaries to optimize waste mined during the project period;
  • Modified stockpile strategy for LOM plan to minimize stockpile re-handling of mill feed material;
  • Reviewed owner mining ramp-up assumptions and expanded shift schedules; and
  • During the pre-production period, the truck and shovel equipment utilization has been reduced to account for autonomous commissioning, initial site conditions, and operator skill level. The schedule allows for a one year truck commissioning period.

Processing Plant

The process flowsheet includes a primary/secondary crushing circuit, HPGR tertiary stage, followed by two stages of grinding (ball and vertical milling), gravity concentration and cyanide leaching, gold recovery by CIP, stripping and electrowinning (EW). The HPGR and grinding circuits will target a final product size of P80 100μm. Cyanide destruction and tailings thickening are also integrated in the processing facility. Average recovery is estimated at 91.8% throughout LOM, with gold recovery by gravity estimated at 23%.

The new mine plan contains updated assumptions and inputs for initial ramp-up of the plant. The updated model forecasts early ramp-up to be per design up to about 70% mill utilization. Steady-state is expected to be achieved over 20 months (previously 10 months) achieving a maximum of 92.6% utilization (previously 94%).

Design throughput is for 1,596 tph ore (35,500 tpd) processing capacity but several components including electrical circuit, chutes, pumps and pump boxes are designed for 1,862 tph (42,000 tpd). The maximum throughput potential of the plant was reviewed against McNulty start-up curves, with the Côté Gold plant and technology fitting the type 1 curve. The project economic model assumes a McNulty 1 start-up curve resulting in the processing plant achieving 105% of nameplate capacity, or 37,200 tpd, by year 3.

* Totals may not add up due to rounding

  1. Mining (gross cost incl. CWS) is the mining cost including capitalized waste stripping costs
  2. Mining (net cost excl. CWS) is the mining cost excluding capitalized waste stripping, with this amount being transferred to sustaining capital

Mining Costs

Mining costs are estimated to average $2.62/t of material mined over the LOM. Net mining costs are estimated at $6.20/t processed, which excludes capitalized waste stripping ("CWS") expenditures transferred to sustaining capital based on World Gold Council (WGC) guidelines. A total of 220 Mt of mined material is classified as CWS during the LOM with a small amount in Phase 4 and Phase 5 classified as non-sustaining capital (27 Mt) and the remainder as sustaining capital (193 Mt).

On a cost by cost centre basis, mine haulage accounts for 39% of the mine operating costs. Open pit services accounts for 7% of the mine costs, followed by loading, blasting, and drilling. Contract mining accounts for 6% of the costs and stockpile rehandle accounts for 5%. Other costs include costs for pit dewatering, engineering and geology, and operations and management overhead.

Mining costs increased 15% from the 2021 Technical Report due to a number of factors, including increased headcount and extended ramp up assumptions. Diesel fuel, maintenance parts and supplies, and personnel costs are the largest cost items, followed by contract services, autonomous licence fees, explosives, and tire costs.

Process Costs

Process operating costs over the LOM are estimated to average $7.97/t of processed ore, increasing 7.7% from the 2021 Technical Report. The cost increases are related to higher contractor maintenance costs for monthly and annual shutdowns, increased maintenance costs in the first three years, and an increase in TMF operations and monitoring costs.

The cost breakdown of operating costs for the processing plant include the following:

  • Reagents represent approximately 25% of the total process operating cost at $1.99/t milled;
  • Wear parts and maintenance supplies represent approximately 22% of the total process operating cost at $1.75/t milled;
  • Grinding media represent approximately 15% of the total process operating cost at $1.19/t milled;
  • Personnel costs represent approximately 15% of the total process operating cost at $1.21/t milled;
  • The cost of the assay laboratory contract represents approximately 4% of the total process operating costs at $0.34/t milled; and
  • Power costs represent approximately 14% of the total process operating cost at $1.09/t milled.

G&A and other

G&A costs over the LOM are estimated to average $3.31/t, an increase of 13.8% from the 2021 Technical Report due to a number of factors, including increased headcount over the LOM, increases in daily camp rates, continuation of site services post construction-phase with associated increases in owner's costs.

Sustaining Capital

Total post-production sustaining capital expenditures are estimated at $1,136 million, which includes CWS ($462 million), capital investments to sustain production including additions to the mining fleet and annual TMF build-out costs ($518 million), and lease payments on the initial mining fleet ($156 million). This excludes $16 million for the permanent camp which is fully commissioned. Reclamation and closure costs are estimated to total $83 million.

Economics

On a go forward basis from May 1, 2022, the after-tax NPV5% of the Côté Gold project is estimated at $1,109 million with an implied after-tax IRR of 13.5% assuming long-term metal prices of $1,600/oz Au ($1,700/oz in 2024 and 2025). At spot metal prices of $1,775/oz Au over the LOM, the Côté Gold project has an estimated after-tax NPV5% of $1,558 million and implied after-tax IRR of 16.5%.

The Company cautions that potential further disruptions, including, without limitation caused by COVID-19, the Ukraine war, inflation, other global supply chain disturbances, weather, labour disputes and the tight labour market could continue to impact the timing of activities, availability of workforce, productivity and supply chain and logistics and, consequently, could further impact the timing of production and, consequently, project costs.

Other Opportunities

Gosselin

On October 18, 2021, IAMGOLD reported an initial Mineral Resource estimate for the Gosselin deposit, located immediately adjacent to the Côté deposit. As outlined in the 2021 Technical Report, Gosselin Indicated Resources total 124.5 Mt at an average grade of 0.84 g/t Au, containing 3.4 Moz Au. An additional 72.9 Mt at an average grade of 0.73 g/t Au, containing 1.7 Moz Au are estimated in the Inferred Mineral Resource category. The Mineral Resources are estimated at a 0.3 g/t Au cut-off grade, based on a price of $1,500/oz Au, and have an effective date of October 4, 2021.

Diamond drilling to date has delineated wide intervals of low-grade gold mineralization hosted in altered and brecciated intrusive lithologies similar to that observed at the adjacent Côté Gold deposit, extending from the Young-Shannon historical shaft in the west to the Gosselin zone in the east. Drilling to date has outlined mineralization over a strike length of 1,400 metres, width of 400 metres and a depth extent of 425 metres. The deposit outcrops below the shallow Three Ducks Lake, and remains open at depth, to the northwest, and along strike to the northeast and southwest.

During the first quarter 2022, the Company announced remaining assay results from its 2021 delineation diamond drilling program at the Gosselin zone confirming expected grades within the modelled resource, and in some cases, the extension of the mineralization zone outside the resources boundaries of the mineralization model (see news release dated January 27, 2022).

Gosselin Mineral Resources are not included in the current Côté Gold LOM plan and represent potential for future mine life extensions.

Processing Expansion

The Côté Gold processing plant has a target throughput of 37,200 tpd, while a significant proportion of the components, including electrical circuit, chutes, pumps and pump boxes have a capacity design of 42,000 tpd. A potential plant expansion requires further study and would be subject to a capital allocation decision at a future date when appropriate. There is no guarantee that a plant expansion will be undertaken.

Exploration upside

The Côté Gold project is located along the South-Western extension of the prolific Abitibi Belt. The land package totalling 596 km2 is a continuous property spanning 65 km in the South Swayze Green Stone Belt. Historic exploration on the property was focused on orogenic, narrow-vein gold zones, with little exploration for Côté/Gosselin style intrusion-hosted deposits.

NON-GAAP FINANCIAL MEASURES

This news release contains non-GAAP financial measures, including cash costs per ounce sold ("COC"), AISC per ounce sold, sustaining and expansion capital expenditures, average realized gold price and available liquidity. The Company believes that, in addition to conventional financial measures prepared in accordance with IFRS, certain investors use these non-GAAP financial measures to assess the performance of the Company. These non-GAAP financial measures do not have any standardized meaning prescribed by IFRS, may not be comparable to similar measures presented by other companies and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Cash costs include mine site operating costs such as mining, processing, administration, royalties, production taxes, and realized derivative gains or losses, exclusive of depreciation, reclamation, capital expenditures and exploration and evaluation costs. AISC include cost of sales exclusive of depreciation expense, sustaining capital expenditures, which are required to maintain existing operations, capitalized exploration, sustaining lease principal payments, environmental rehabilitation accretion and depreciation, by-product credits, and corporate general and administrative costs. These costs are then divided by the Company's attributable gold ounces sold by mine sites in commercial production in the period to arrive at COC and AISC per ounce sold. The Company believes that the use of COC and AISC per ounce sold metrics will assist analysts, investors and other stakeholders of the Company in assessing its operating performance and its ability to generate free cash flow.

The Company presents its sustaining capital expenditures in its all-in sustaining costs to reflect the capital related to producing and selling gold from its mine operations. The distinctions between sustaining and expansion capital used by the Company align with the guidelines set out by the World Gold Council. Expansion capital is capital expenditures incurred at new projects and capital expenditures related to major projects or expansion at existing operations where these projects will materially benefit the operations. This non-GAAP financial measure provides investors with transparency regarding the capital expenditures required to support the ongoing operations at its mines, relative to its total capital expenditures.

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING DISCLOSURE OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

The mineral resource and reserve estimates contained in this news release have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards").. These standards are similar to those used by the United States Securities and Exchange Commission (the "SEC") Industry Guide No. 7, as interpreted by the SEC staff. However, the definitions in NI 43-101 and the CIM Standards differ in certain respects from those under Industry Guide 7. Accordingly, mineral resource and reserve information contained in this news release may not be comparable to similar information disclosed by United States companies. Under the SEC's Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

As a result of the adoption of amendments to the SEC's disclosure rules (the "SEC Modernization Rules"), which more closely align its disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101 and the CIM Standards, and which became effective on February 25, 2019, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended definitions of "proven mineral reserves" and "probable mineral reserves" in its amended rules, with definitions that are substantially similar to those used in NI 43-101. Issuers must begin to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021, though Canadian issuers that report in the United States using the Multijurisdictional Disclosure System ("MJDS") may still use NI 43-101 rather than the SEC Modernization Rules when using the SEC's MJDS registration statement and annual report forms.

United States investors are cautioned that while the SEC now recognizes "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under the SEC Modernization Rules, investors should not assume that any part or all of the mineral deposits in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility. Under Canadian regulations, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in limited circumstances.

Investors are cautioned not to assume that any "measured mineral resources", "indicated mineral resources", or "inferred mineral resources" that the Company reports in this news release are or will be economically or legally mineable. Further, "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 any part or all of an inferred mineral resource will ever be upgraded to a higher category.

The mineral reserve and mineral resource data set out in this news release are estimates, and no assurance can be given that the anticipated tonnages and grades will be achieved or that the indicated level of recovery will be realized.
