Americas Gold & Silver reports high-grade Cosalá hits
USAS reports high-grade Cosalá drill intercepts that it expects to feed into an optimized mine plan and future resource update by 2027.
Rhea-AI Filing Summary
Americas Gold & Silver Corp (USAS) reports high-grade silver-copper drill results from its 2026 resource conversion program at the Cosalá Complex in Mexico, targeting the San Rafael Upper, 120 Upper and 120 Lower deposits. The company states that multiple holes returned substantially higher silver grades than the currently modeled Mineral Resource and that these intercepts were not included in its 2025 Mineral Resource and Reserve statement.
Key results include hole SR583 with a true thickness of 20.5 meters grading 654.7 g/t Ag and 1.5% Cu, located about 30 meters outside the 2025 inferred resource boundary, and hole 120-26-G141 with 14.1 meters grading 409.3 g/t Ag and 0.8% Cu
Americas Gold & Silver states it is preparing an optimized mine plan for the Upper and Lower 120 deposit and anticipates mine development to access this zone in the second half of 2027. The company highlights Cosalá as an important contributor to its broader multi-asset growth strategy focused on silver and antimony production to support AI, electrification, advanced manufacturing and national security applications.

Filing Explained
The assays expand the evidence base for a future mine plan, not the currently reported mineral resource and reserve.
This Form 6-K furnishes material home-market information; Americas reports 2026 infill and step-out drill results from the Cosalá Complex. The disclosed structural consequence is prospective: the results may inform a later resource estimate and mine plan rather than changing the currently reported resource and reserve statement.
The company describes the results as having significant upside potential, but also states that they were not included in its 2025 Mineral Resource and Reserve statement and are expected to be incorporated into its next resource estimate and mine plan in 2027. The filing therefore reports exploration evidence, not a completed resource or mine-plan revision.
The release says 44 drillholes are reported from 55 total, with the reported intercepts directly adjacent to existing infrastructure; it says the drilling confirms modeled resource thickness and may increase average silver grades in the San Rafael Upper and 120 zones.
The company cautions that its mineral-resource and reserve information follows Canada's NI 43-101 standards and may not qualify as mineral resources or reserves under SEC standards, so comparisons with disclosures from domestic SEC-reporting companies may not be like-for-like.

AMERICAS GOLD AND SILVER ANNOUNCES SOME OF THE BEST GRADE-WIDTHS DRILLED TO DATE AT THE COSALA
COMPLEX INCLUDING HIGH-GRADE DRILL RESULTS OF 654.7 G/T AG, 1.5% CU OVER 20.5 METERS AND 409.3 G/T
AG, 0.8% CU OVER 14.1 METERS
TORONTO, ONTARIO - September 17, 2026 - Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) ("Americas" or the "Company") a North American producer of silver and other critical minerals supporting artificial intelligence ("AI"), electrification, national security and advanced manufacturing, is pleased to announce high-grade Ag-Cu drill results from the Company's ongoing resource conversion drilling program at the Cosalá Complex. The assays released are a result of infill and step-out drilling conducted in 1H 2026 at the San Rafael Upper, 120 Upper and 120 Lower deposits with multiple holes at all three zones returning substantially higher silver grades than the currently modeled resource. These results represent significant upside potential to the future mine plan as they were not included in the Company's 2025 Mineral Resource and Reserve statement (see Americas news release dated March 30, 2026).
Paul Andre Huet, Chairman and CEO, commented: "The Cosalá operation continues to significantly exceed expectations, and I'd like to congratulate the entire team in Mexico for their commitment to mining excellence at all levels of the operation.
Resource conversion drilling at the San Rafael Upper and 120 zones is consistently averaging 2-3x the previously reported inferred Mineral Resource grades. Today's results are highlighted by hole SR583, which intersected a true thickness of 20.5 meters grading 654.7 g/t Ag and 1.5% Cu. It's important to note that this intercept is located just 30 meters outside of the 2025 inferred resource boundary and is expected to contribute new, high-grade silver ounces to the Cosalá mine plan. On a gram-meter basis these intercepts are comparable with some of the best silver intercepts drilled anywhere in Mexico over the past year.
Overall, 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. Over the remainder of 2026 and into 2027, we will continue unlocking value with the drill bit at Cosalá and are looking forward to incorporating these results into our next resource estimate and mine plan in 2027. As the results have demonstrated this year, Cosalá is certainly an exciting and meaningful contributor to our multi-asset growth strategy underway at Americas Gold & Silver."
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 versus the 2025 reported Mineral Resource grades. 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 H2 2027.
