Astra drills 5,199 m at La Manchuria to date

Mr. Brian Miller reports ASTRA PROVIDES PROGRESS UPDATE ON PHASE II DRILL PROGRAM AT LA MANCHURIA GOLD AND SILVER PROJECT, ARGENTINA Astra Exploration Inc. has provided a progress update on exploration activities at the La Manchuria gold and silver project in Santa Cruz, Argentina. The company is approximately halfway through its 10,000-metre phase II drill program, with 5,119 metres of diamond drill holes in 25 holes currently completed. Initial assays are expected in December, with the bulk of results returned in early 2026. Drilling has paused for results and will resume in early 2026. Current phase II highlights include: Significant strike extension of the West Feeder vein system; A newly constructed 3-D geophysical model is accurately predicting veins below surface; Veins and/or veinlets encountered in every drill hole; Definition of the first continuous vein at Eastern zone; A new parallel vein structure approximately 350 metres northeast of the Eastern zone. Astra's exploration director, Diego Guido, commented: "The phase II drill program was designed to test lateral extensions of the shallow epithermal vein system and to test a new 3-D geophysical targeting model. All of the drill holes intersected veins and/or veinlets with clear evidence of mineralization in some of them. "The strike length of the Main zone has been extended from approximately 500 to 800 metres, particularly in the West Feeder veins. We have also confirmed the first continuous vein of at least 200 metres of strike length and up to 150 metres deep in the Eastern zone and have intersected a new parallel structure about 350 metres northeast of the Eastern zone. The recently constructed 3-D geophysical model has demonstrated to be a powerful tool for targeting mineralized veins beneath surface. We will continue testing the model with more drilling inside the existing survey boundary and will expand that survey to other areas of the project prior to restarting drilling." Program details Prior to drilling, the company completed a comprehensive program of detailed geological mapping, together with the compilation and reprocessing of geophysical data. Regional ground magnetics were expanded with an additional 150 line kilometres, and raw geophysical data were reprocessed to improve the delineation of known vein-hosting structures. This work supported the development of a predictive 3-D geophysical model for targeting new epithermal veins. The resistivity reprocessing clearly identifies fault blocks and the best elevations to target prospective veins in the downthrown blocks to the northwest and southeast areas of the West Feeder vein system in the Main zone. The West Feeder vein system hosts some of the thickest veins and highest grades currently known in the system. An additional four holes were drilled at the Eastern zone, allowing for the first interpretation of vein continuity within this previously underexplored area of the shallow epithermal vein system. These new holes confirmed a fault-related vein with a minimum strike length of approximately 200 metres and 150 metres deep below the surface. The company also completed the first two drill holes at a newly defined target located 350 metres east of the Eastern zone, now referred to as the Road zone. Astra to present at the Precious Metals & Critical Minerals Virtual Investor Conference Astra's chief executive officer, Brian Miller, will give a live presentation followed by an open question-and-answer session at 4 p.m. Eastern Time on Dec. 3. Those wishing to attend Astra's presentation can register on-line. Investors may also request to schedule a one-to-one meeting with Astra's CEO on Dec. 5, Dec. 8 and Dec. 9 by confirming a time on-line. This will be a live, interactive on-line event where investors are invited to ask the company questions in real time. If attendees are not able to join the event live on the day of the conference, an archived webcast will also be made available after the event. It is recommended that on-line investors preregister and run the on-line system check to expedite participation and receive event updates. About Astra Exploration Inc. Astra Exploration is a precious metals exploration company based out of Vancouver, B.C. 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-per-cent 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 in Santa Cruz, Argentina. The 100-per-cent-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 Penon. The 100-per-cent-owned Cerro Bayo project in northern Chile is located in the Maricunga belt approximately 20 kilometres from the Refugio mine. The project hosts a high-sulphidation epithermal (HSE) plus or minus 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.
