Astra Provides Progress Update on Phase II Drill Program at La Manchuria Gold and Silver Project, Argentina

Core Insights - Astra Exploration Inc. is providing a progress update on its exploration activities at the La Manchuria Gold and Silver Project in Santa Cruz, Argentina, highlighting significant advancements in its Phase II drill program [1][7]. Phase II Drill Program - The company is approximately halfway through its 10,000 metre Phase II drill program, having completed 5,119 metres of diamond drilling in 25 holes, with initial assay results expected in December and the majority in early 2026 [2][3]. - Drilling has paused for results and is set to resume in early 2026 [2]. Exploration Highlights - The Phase II drill program aims to test lateral extensions of the shallow epithermal vein system and a new 3-D geophysical targeting model, with all drill holes intersecting veins and/or veinlets showing evidence of mineralization [3][4]. - The strike length of the Main Zone has been extended from approximately 500 to 800 metres, particularly in the West Feeder veins, and a continuous vein of at least 200 metres of strike length has been confirmed in the Eastern Zone [4][8]. - A new parallel structure has been intersected about 350 metres northeast of the Eastern Zone, demonstrating the effectiveness of the 3-D geophysical model in targeting mineralized veins [4][8]. Geological and Geophysical Work - Prior to drilling, the company conducted detailed geological mapping and reprocessing of geophysical data, expanding regional ground magnetics by an additional 150 line-kilometres [5]. - The resistivity reprocessing has identified fault blocks and optimal elevations for targeting prospective veins in the West Feeder area, which hosts some of the thickest and highest-grade veins known in the system [6]. Future Plans - The company plans to continue testing the 3-D geophysical model with more drilling within the existing survey boundary and expand the survey to other areas of the project before resuming drilling [4].
