Americas Gold and Silver Announces New Major Discoveries in Idaho and Mexico and a Strong 2025 Resource and Reserve Update Including a 19% Year over Year Increase in M&I Mineral Resources

About this update from Americas Gold And Silver Corporation

Toronto, Ontario - 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 that its consolidated silver Measured and Indicated ('M&I') Mineral Resources has increased by 10%, or 11 million ounces, and consolidated silver Inferred Mineral Resources has increased by 15%, or 17 million ounces, both net of mining depletions. Resource and Reserve Highlights Consolidated silver M&I Mineral Resources increased by 10% to 115.7 million ounces, grade increased by 30% to 239.8 g/t Inferred Mineral Resources increased by 15% to 133.3 million ounces, grade decreased by 13% to 264.0 g/t Galena silver M&I Mineral Resources increased by 19% to 87.9 million ounces, grade increased by 21% to 500.9 g/t Inferred Mineral Resources increased by 3% to 105.7 million ounces, grade increased by 7% to 498.2 g/t Proven & Probable Reserves increased by 2% to 16.3 million ounces, grade increased by 21% to 482.1 g/t Cosala silver M&I Mineral Resources decreased by 13% to 18.7 million ounces, grade increased by 33% to 119.3 g/t Additionally, with the acquisition of the Cresent Silver Mine , the Company added a very high-grade Historical M&I Mineral Resource of 3.8 million silver ounces at 654 g/t and Historical Inferred Mineral Resource of 19.1 million silver ounces at 665 g/t, which will be operated as part the Galena Complex in Idaho . Exploration Highlights Galena Complex - Major new discovery of the 520 Vein in the Coeur Mine 520 Vein discovery at the Coeur Mine , part of the Galena Complex where drilling has intersected multiple high-grade Ag-Cu-Sb intercepts, including 1.1m @ 619.0 g/t Ag, 1.1% Cu, 0.65% Sb in drillhole C034-166. Four drillholes to-date have defined a 150m long by 150m high mineralized vein that is open in all directions. This new discovery increases the operational flexibility at Galena with the potential introduction of a new Ag-Cu-Sb mining area located directly in line with the recently upgraded Coeur Shaft. 034 Vein discovery at the Galena Mine . Infill and step-out drilling is in progress to follow up on previously announced high-grade intercepts including 4,458 g/t Ag, 3.34% Cu and 1.50% Sb over 0.5m in drillhole 52-S54. 149 Vein discovery at the Galena Mine . Infill and step-out drilling is in progress to follow up on previously announced high-grade intercepts including 24,913 g/t Ag and 16.9% Cu over 0.2m in drillhole 43-317. Four underground core rigs are currently completing infill and step-out drilling in 2026 for a total of 25,022 meters. Cosala Mine - Near mine high-grade discovery New El Alacran discovery 600 meters to the north of the San Rafael mine has intersected multiple Ag-Au-Cu intercepts including 27.6m @ 69.0 g/t Ag, 0.2 g/t Au, 0.2% Cu, Including: 11.2m @ 91.0 g/t Ag, 0.1 g/t Au, 0.3% Cu And: 4.6m @ 69.0 g/t Ag. 0.1 g/t Au EAS26-001. Step-out drilling at the El Alacran and La Tania targets are in progress. One surface and one underground core rig are currently completing infill and step-out drilling in 2026 for a total of 11,710 meters. Paul Andre Huet , Chairman and CEO, commented: 'Our inaugural Resource and Reserve update under the strengthened team at Americas has delivered outstanding results. Since we began the initiative to recapitalize, analyze, and expand operations at Galena in early 2025, our exploration focus has been on adding high-quality, high-grade ounces to a new Resource and Reserve estimate that we can use as the foundation of our growth plan for years to come. 'In our new M&I Resource at Galena, we have seen very strong ounce growth of 19% year over year with a tremendous 21% improvement in grades to 501g/t silver. This increase across the board demonstrates what Galena has already done for over 100 years of mining history: replace depletion, add ounces and continue to establish itself as one of the highest grade primary silver systems in the world. We are extremely excited about what the future holds at Galena, where we already have the major infrastructure in place around this expanding Resource to exploit what is a world class high-grade system. 'Our drilling campaign in 2025 was highlighted by two major new discoveries: the 034 Vein and 149 Veins. High grade intercepts, including 4,458 g/t Ag, 3.34% Cu and 1.50% Sb over 0.5 meters and 1,199 g/t Ag, and 0.85% Cu over 2.0 meters led us to follow up on these areas which have now expanded from major targets into future potential mining centers (with the 034 Vein now included in our updated Resource). 'Looking ahead to 2026, we have announced the largest exploration drilling campaign and budget in the Company's history, with 64,000m to be drilled across our properties, totaling up to $20 million . This decision has been reinforced by yet another recent discovery - the 520 Vein in our Coeur mine. Not only has this new copper-silver-antimony vein already returned strong grades of over 600g/t silver, it represents a new potential mining front at Galena while we continue to complete the mine development work this year to scale the operation significantly into the future. The Coeur mine is directly connected underground to our Galena mine on the 3400 level and is part of the same system where we made the strategic decision to upgrade the Coeur hoist ahead of schedule in late 2025. With numerous potential new mining fronts identified in our drill target database, we look forward to unlocking even more value with the drill bit in this world class complex during 2026. 'In Mexico, our regional drilling exploration efforts have been limited yet very effective. The discovery at El Alacran is just 600m from our San Rafael mine, where we recently completed mining in 2025. The high-grade discovery near surface represents a strong example of the tremendous potential of this property that has not seen major exploration expenditure for many years. While we continue to ramp up the EC120 mine, we are very much looking forward to drilling out El Alacran and other targets across the large land package with the potential to significantly extend mining operations into the future. 'Overall, I am proud of our strengthened exploration team's efforts this past year and am very much looking forward to seeing what we can deliver with a robust exploration budget and program in 2026. The future is bright.' About Americas Gold and Silver Corporation Americas Gold and Silver is a rapidly growing North American mining company producing silver, copper, and antimony from high-grade operations in the U.S. and Mexico . In December 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. This transaction consolidated Galena as a cornerstone U.S. silver asset and the nation's largest antimony mine. In December 2025 , Americas acquired the fully permitted, past-producing Crescent Silver Mine (9 miles from Galena) with the world's 3rd highest-grade silver resource, creating significant potential future synergies through shared infrastructure and processing. In February 2026 , Americas formed a 51/49 joint venture with US Antimony to build a new antimony processing hub at Galena, creating a U.S. 'mine-to-finished product' antimony solution. Americas also owns and operates the Cosala Operations in Sinaloa, 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.
