Astra Provides Update on Drill Program at La Manchuria Project, Argentina

Vancouver, British Columbia--(Newsfile Corp. - May 21, 2025) - Astra Exploration Inc. (TSXV: ASTR) (OTCQB: ATEPF) (FSE: S3I) ("Astra" or the "Company") is pleased to provide an update on exploration activities at the La Manchuria Gold and Silver Project in Santa Cruz, Argentina.

Astra has completed eleven DDH holes for a total of 2,468 metres and submitted core samples for analysis. Assay results are expected to be received beginning in early June.

Astra's CEO, Brian Miller, commented:

"Our plan for La Manchuria was to find extensions of high-grade veins, at depth and along strike. We have also targeted new veins to the southwest and northeast of drilling to date as well. The program has progressed quickly and, more importantly, has intersected quartz veins and/or veinlets in all holes, and there are discrete zones of observable mineralization. We are encouraged by field observations and look forward to receiving assay results over the coming weeks. I'd like to specifically acknowledge that despite some adverse weather conditions, the drill program remained on schedule due to the steadfast efforts by Astra personnel and contractors, and thanks to the cooperation and support from Fomicruz and Patagonia Gold."

Program Details

The goal of Astra's initial drill program is to test a new geological model for extending the high-grade gold and silver mineralization beyond the 2019 resource¹ area, and into previously undrilled zones (see yellow zones 1-4 in Figure 1). Drilling targeted the extension of known veins and mineralized faults along strike and at depth (zone 1 in Figure 1), tested for new structures parallel to known structures (zones 2 & 3 in Figure 1) and also tested the Eastern Zone (zone 4 in Figure 1) at depth and along strike with two holes.

The drilling, completed to date, was successful in intersecting new quartz vein structures outside the limits of past drilling thus confirming our geologic model and interpretation. Also noteworthy is that the post-mineral breccia which conceals the vein and fault extension to the southeast (green area within zone 1 in Figure 1) is getting thinner (vertical thickness) to the southeast. This indicates a thicker vertical horizon of rhyolitic tuff to the southeast, which is the most favorable host rock identified to date.

These results and pending assays, in conjunction with the large dataset from past exploration, will serve as the foundation in planning a follow-up drill program in the coming months.

About the Company

Astra Exploration Inc. is a precious metals exploration company based out of Vancouver, BC, that is actively building a portfolio of high-quality projects in some of the most important mining jurisdictions in Latin America.

The La Manchuria gold-silver project in Santa Cruz, Argentina, over which Astra has an option to acquire 90% interest, is a high-grade gold and silver low sulphidation epithermal (LSE) deposit located in the prolific Deseado Massif which hosts multiple world-class LSE precious metals deposits, including Cerro Vanguardia and Cerro Negro, Santa Cruz, Argentina.

The 100% owned Pampa Paciencia gold and silver project in northern Chile is located in the Paleocene mineral province in proximity to such major operating mines as Spence and Sierra Gorda. The project shares several important geological similarities to other Paleocene LSE gold-silver deposits including Faride and El Peñón.

The 100% owned Cerro Bayo project in northern Chile is located in the Maricunga belt approximately 20 km from the Refugio Mine. The project hosts a high sulphidation epithermal (HSE) +/- porphyry gold system with similarities to the Salares Norte deposit to the north in the same belt. The Maricunga belt is one of the most endowed regions in the world for gold and copper deposits.
