Americas Gold and Silver Announces Largest Ever Exploration Program in 2026 Following the Discovery of Ten New High-Grade Silver-Copper-Antimony and Silver-Lead Veins at Galena Including 4,896 g/t Silver and 3.95% Copper over 1.3M

Toronto, Ontario--(Newsfile Corp. - March 12, 2026) - Americas Gold and Silver Corporation

) ("Americas" or the "Company") a growing North American precious metals and antimony producer, is pleased to announce the discovery of seven new high-grade silver-copper-antimony veins and three new high-grade silver-lead veins at the Galena Complex (Figure 1 and Table 1). The Company is also pleased to announce the largest drilling campaign in Company history with a total of approximately 64,000 meters to be drilled across both the Galena Complex (including the Crescent Mine) and Cosalá in 2026.

• Hole 55-261: 4,896 g/t Ag and 3.95% Cu over 1.3 meters

  , and
• Hole 43-310: 2,563 g/t Ag and 1.35% Sb over 0.7 meters
  1
• 2026 exploration drilling campaign to total approximately 64,000 meters across Idaho and Mexico operations

The intercepts announced today were drilled as part of the Company's near-mine exploration efforts in late 2025 and represent ten new vein discoveries with materially higher silver grades than the current Galena Complex Mineral Resource and Mineral Reserves (see December 31, 2024 Mineral Resource and Mineral Resource estimate ). Drilling also returned numerous parallel and splay vein intercepts adjacent to active mine workings, which represent near-term growth opportunities that warrant aggressive follow-up drilling in 2026.

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 Cosalá 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.

The scientific and technical information relating to the operation of the Company's material operating mining properties contained herein has been reviewed and approved by Rick Streiff, Certified Professional Geologist (CPG#11108), EVP, Geology of the Company. The Company's current Annual Information Form and the NI 43-101 Technical Reports for its other material mineral properties, all of which are available on SEDAR at , and EDGAR at , 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 NQ-size core and BQ-size core. The Company's standard QA/QC practices were utilized to ensure the integrity of the core and sample preparation at the Galena Complex through delivery of the samples to the assay lab. The drill core was stored in a secure facility, photographed, logged and sampled based on lithologic and mineralogical interpretations. Standards of certified reference materials, field duplicates and blanks were inserted as samples shipped with the core samples to the lab.

Analytical work was carried out by American Analytical Services Inc. ("AAS") located in Osburn, Idaho, or SVL Analytical located in Kellogg Idaho. AAS and SVL are independent, ISO-17025 accredited laboratories. Sample preparation includes a 30-gram pulp sample analyzed by atomic absorption spectrometry ("AA") techniques to determine silver, copper, and lead, using aqua regia for pulp digestion. Samples returning values over 514 g/t Ag are re-assayed using fire-assay techniques for silver. Additionally, samples returning values over 23% Pb are re-assayed using titration techniques.

Duplicate pulp samples are sent out quarterly to ALS Global, an independent, ISO-17025 accredited laboratory based in Reno, Nevada to perform an independent check analysis. A conventional AA technique was used for the analysis of silver, copper and lead at ALS Global with the same industry standard procedures as those used by AAS. The assay results listed in this report did not show any significant contamination during sample preparation or sample bias of analysis.
