High-grade Cosalá drilling results reported by Americas Gold & Silver (NYSE: USAS)
Rhea-AI Filing Summary
Americas Gold and Silver Corporation reported high-grade infill drilling results from its Cosalá Complex in Mexico. Fourteen resource conversion holes drilled in Q4 2025 and Q1 2026 at the San Rafael Upper, 120 Upper and 120 Lower zones returned substantially higher silver grades than the current Mineral Resource model.
Highlight intercepts include hole SR568 with 14.0 meters grading 599.8 g/t silver and 0.83% copper in an area that had modeled silver grades of 110 g/t, and hole SR566 with 10.0 meters at 509.7 g/t silver. The company states these results represent potential significant upside to future mine plans and are adjacent to existing mine infrastructure.
The new data, not included in the October 31, 2025 Mineral Resource and Reserve statement, is being incorporated into an optimized mine plan for the second half of 2026 as part of what management describes as the most aggressive drilling campaign in the company’s history.
Positive
- None.
Negative
- None.
Insights
High‑grade Cosalá infill results suggest potential mine plan upside but no resource update yet.
The company reports infill drilling at the Cosalá Complex with silver grades well above the modeled Mineral Resource in the San Rafael Upper and 120 zones. Intercepts such as SR568 (14.0 m at 599.8 g/t Ag) and several 120 zone holes show thick, high-grade intervals adjacent to existing workings.
Because these holes post-date the October 31, 2025 Mineral Resource cutoff, they are not yet reflected in official reserves/resources. Management indicates they will incorporate the intercepts into an optimized mine plan for H2 2026, as part of a large 2026 drilling campaign. Actual economic impact will depend on a future resource update, costs, and metal prices.

AMERICAS GOLD AND SILVER ANNOUNCES HIGH-GRADE INFILL DRILL RESULTS AT THE COSALÁ COMPLEX HIGHLIGHTING SUBSTANTIAL UPSIDE COMPARED TO MINERAL RESOURCE GRADES, INCLUDING 599.8 G/T AG, 0.8% CU OVER 14.0M AND 509.7 G/T AG, 0.4% CU OVER 10.0M
TORONTO, ONTARIO - June 1, 2026 - Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) ("Americas" or the "Company"), a growing North American precious metals and antimony producer, is pleased to announce high-grade drill results from the Company's ongoing resource conversion drilling program at the Cosalá Complex. Drilling was conducted in Q4 2025 through Q1 2026 at the San Rafael Upper, 120 Upper and 120 Lower zones with drilling 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 reported after the October 31, 2025, Mineral Resource cutoff date, and therefore not included in the Company's recently announced Mineral Resource and Reserve statement (see Americas news release dated March 30, 2026).
The 14 reported drillholes have not only confirmed the modeled thickness of the Mineral Resource but also represent a potential substantial increase in average silver grades in the San Rafael Upper and 120 zones versus the 2026 reported Mineral Resource grades. All reported drill intercepts are directly adjacent to existing infrastructure and are currently being incorporated into an optimized mine plan heading into H2 2026.
Paul Andre Huet, Chairman and CEO, commented: "Today's results at Cosalá are truly spectacular and I'd like to congratulate the Cosalá team who continue to exceed expectations at every level. Mineral Resource conversion drilling at the San Rafael Upper and 120 zones is consistently averaging 2-3x the previously reported inferred Mineral Resource grades. Furthermore, the highlight intercept in hole SR568 intersected 14.0 meters grading 599.8 g/t Ag in a section of the Mineral Resource that predicted silver grades of 110 g/t, representing more than 5x potential upgrade to the grades in that area when compared to our current Mineral Resource. These excellent drill intercepts are immediately adjacent to existing mine infrastructure, and we are looking forward to incorporating these results into our optimized mine planning process as we move into H2 2026.
The Company is on track to complete the most aggressive drilling campaign in company history in 2026, and today's results further highlight the incredible potential remaining to be unlocked with the drill bit at each of our operations."

About Americas Gold and Silver Corporation
Americas Gold & Silver is a rapidly growing North American mining company producing silver, copper, and antimony from high-grade operations in the U.S. & Mexico. In Dec. 2024, Americas acquired 100% ownership of the Galena Complex (Idaho) in a transaction with Eric Sprott, former 40% Galena owner, in exchange becoming Americas' largest shareholder at ~14%. This unitized Galena as a cornerstone U.S. silver asset and the nation's largest antimony mine. In Dec. 2025, Americas acquired the fully permitted, past-producing Crescent Silver Mine (9 mi from Galena), creating significant potential future synergies through shared infrastructure & processing. Americas also owns & operates the Cosalá Ops. in Mexico. Americas is fully funded to aggressively grow production at the Galena Complex, Crescent and in Mexico with an aim to be a leading North American silver producer and a key source of U.S.-produced antimony.

The diamond drilling program used HQ and NQ-size core with core stored in a secure facility, photographed, logged and sampled based on lithologic and mineralogical interpretations. The Company's standard QA/QC practices are utilized with standards of certified reference materials, field duplicates and blanks inserted into the sample stream prior to shipment to the ALS Chemex de Mexico prep lab in Hermosillo, Sonora, Mexico. ALS Chemex de Mexico is a ISO/IEC 17025-accredited laboratory, which utilizes industry standard sample preparation procedures, including crushing, pulverizing, and internal quality control protocols. Following preparation, 150 gram pulp aliquots are shipped to ALS Vancouver, Canada, for analysis.
Gold analyses is performed by atomic absorption spectrometry (AA). Silver, copper, lead, and zinc are analyzed following four-acid digestion with an ICP-AES finish (method ME-OG62). Samples returning silver values above the upper detection limit of 1,500 ppm Ag are re-analyzed by fire assay with a gravimetric finish (method AG-GRA21).All mining terms used herein have the meanings set forth in National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), as required by Canadian securities regulatory authorities.

FAQ
What did Americas Gold and Silver (USAS) report in its latest Cosalá drilling update?
Americas Gold and Silver reported high-grade infill drilling results at the Cosalá Complex. Fourteen holes in the San Rafael Upper and 120 zones showed substantially higher silver grades than the current Mineral Resource model, with several thick, high-grade intercepts near existing mine infrastructure.
What are the key high-grade drill intercepts reported by Americas Gold and Silver at Cosalá?
Key intercepts include SR568 with 14.0 meters grading 599.8 g/t silver and 0.83% copper, and SR566 with 10.0 meters at 509.7 g/t silver. Several 120 zone holes returned 20–45 meter widths with silver grades above 180 g/t, indicating strong mineralization continuity.
How might the new Cosalá drill results affect Americas Gold and Silver’s mine plan?
The company states that infill drilling indicates substantially higher silver grades than modeled, representing potential upside to future mine plans. These results are being incorporated into an optimized mine plan for the second half of 2026, focused on the San Rafael Upper and 120 zones.
Are the new Cosalá drill results included in Americas Gold and Silver’s current Mineral Resource and Reserve statement?
No. The 14 reported holes were completed after the October 31, 2025 Mineral Resource cutoff date. As a result, they were not included in the company’s 2026 Mineral Resource and Reserve statement and will need to be captured in future technical updates.
What is Americas Gold and Silver’s broader growth strategy around the Galena, Crescent, and Cosalá assets?
The company describes itself as a rapidly growing North American producer of silver, copper, and antimony. It now owns 100% of the Galena Complex, has acquired the fully permitted Crescent Silver Mine, and operates Cosalá, aiming to aggressively grow production across these operations.
Who reviewed the technical information in Americas Gold and Silver’s Cosalá drilling update?
The scientific and technical information was reviewed and approved by Rick Streiff, a Certified Professional Geologist and the company’s Executive Vice President, Geology. The disclosure follows Canadian NI 43-101 standards, which differ from U.S. SEC reporting requirements.
