Americas Gold and Silver Reports High-Grade Silver and Copper Drill Results at Cosala Complex
News related to:Americas Gold and Silver Corporation · 2 min read
Americas Gold and Silver Corporation has announced some of the best grade-widths drilled to date at the Cosala Complex, with high-grade silver and copper results from ongoing resource conversion drilling. The company reported drill results from the San Rafael Upper, 120 Upper, and 120 Lower deposits, with multiple holes at all three zones returning significantly higher silver grades than the currently modeled resource.
The most notable result came from hole SR583, which intersected a true thickness of 20.5 meters grading 654.7 grams per tonne (g/t) of silver and 1.5% copper. This intercept is located just 30 meters outside the 2025 inferred resource boundary and is expected to contribute new, high-grade silver ounces to the Cosalá mine plan.
Huet also noted that these results are comparable with some of the best silver intercepts drilled anywhere in Mexico over the past year. The company's resource conversion drilling at the San Rafael Upper and 120 zones is consistently averaging two to three times the previously reported inferred mineral resource grades.
The 44 reported drillholes (55 total) continue to confirm the modeled thickness of the mineral resource and represent a potential opportunity to increase the average silver grades in the San Rafael Upper and 120 zones. All reported drill intercepts are directly adjacent to existing infrastructure, with portions of the San Rafael deposit already in production.
The company is in the process of creating an optimized mine plan for the Upper and Lower 120 deposit and anticipates mine development to access this high-priority zone in the second half of 2027. The results have demonstrated significant exploration success at Cosala in 2026, a demonstration of the significant value still to be captured by a robust exploration program.
Huet added, "The tremendous exploration success being delivered at Cosalá in 2026 is a demonstration of the significant value still to be captured by a robust exploration program. As a reminder, Cosalá has not received a material exploration budget for many years and we are truly excited at the growth potential of this asset, both in terms of higher grades, as demonstrated today, and potential improvements to the existing mine plan."
The company's flagship Galena Complex in Idaho is one of the United States' premier silver mining districts and includes the nation's largest antimony mine. The Cosalá Operations in Sinaloa, Mexico, where EC120, a high-grade silver-copper mine, is currently being scaled, is a key contributor to the company's multi-asset growth strategy.
The ongoing drilling program is part of Americas Gold and Silver Corporation's strategy to become one of North America's leading silver producers while establishing a secure domestic supply of antimony. The company is well positioned to increase silver and antimony production while supplying the critical minerals needed to support the next generation of artificial intelligence infrastructure, energy systems, and advanced industrial technologies.
