Toronto, Ontario--(Newsfile Corp. - 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."

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 Company's current Annual Information Form and the NI 43-101 Technical Reports for its material mineral properties, all of which are available on SEDAR+ at www.sedarplus.ca , and EDGAR at www.sec.gov , contain further details regarding mineral reserve and mineral resource estimates, classification and reporting parameters, key assumptions and associated risks for each of the Company's material mineral properties, including a breakdown by category.
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.
