Americas Gold and Silver continue discoveries at Galena Complex with a New Galena Mine vein discovery, Idaho

Americas Gold and Silver Corp. [TSX: USA; NYSE American: USAS], a North American producer of silver and other critical minerals supporting artificial intelligence, electrification, national security and advanced manufacturing, reported high-grade Ag-Cu-Pb-Sb drill results from the company’s largest ever exploration and Mineral Resource conversion drilling program at the Galena Complex, comprised of the operating Galena Mine connected to the restart stage Coeur Mine and the neighboring Crescent Mine, Idaho.

The assays reported are a result of substantial infill and step-out exploration drilling conducted across multiple target areas at the Galena, Coeur and Crescent mines. Drilling has delivered new vein discoveries at Galena and Crescent as well returned infill drill intercepts that are regularly intersecting higher silver grades than the currently modeled Mineral 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.

Paul Andre Huet, Chairman and CEO, commented: “The new drilling results at the Galena Complex continue to reaffirm our belief that we control one of the highest-grade, primary silver deposits not only in the historic Silver Valley but worldwide. Our drill program in 2026 has unlocked numerous new discoveries while significantly extending existing major veins on multiple levels of the mine. I’d like to congratulate the entire Galena team for their hard work and exceptional safety record as we continue to identify new targets to feed the mine’s significant future.

“Our recent drilling across the Galena Complex has continued to deliver exceptional results. The new vein discovery on the operating 49 level (49-817 intersecting 1.2 metres of 1,061 g/t Ag, 0.7% Cu and 0.6% Sb) is not only high grade, but also very close to our minimum mining width for our ongoing transition to long hole stoping.

“The high-grade discovery of the 9 Vein (24-407 intersecting 0.4m of 7,123 g/t Ag, 3.24% Cu and 1.81% Sb) in an area without any vein projections is a typical example of the numerous opportunities for new discoveries at Galena, even in higher levels with significant historical mining.

“Moving over to Coeur, the 520 Vein system continues to grow, with recent drilling expanding the 2025 discovery to 200m along strike and 200 metres in vertical extent while all directions remain open for further expansion. I will also note that all our drilling at Galena in 2026 has focused on in-mine exploration above the 6,000-foot level. With neighbouring operating mines along strike extending deeper than 10,000 feet, we have good reason to believe in the further potential below our existing operations.

“At our Crescent mine project, we have been very active with the drill bit. Our goals are twofold: infill drill the existing Mineral Resource at Alhambra and South Veins for detailed mine planning ahead of mining in 2027 and testing for new high-grade shoots.

“In our batch of results containing assays for the first 12 of 45 holes drilled to date, we are proud to announce the discovery of two new veins in the vicinity of Alhambra. Drillholes SF-002 and SF-003 intersected 1.1 metres of 1,109.5 g/t Ag, 0.3% Cu and 0.8 metres of 939.3 g/t Ag, 0.1% Cu, respectively. Coupled with the results from ongoing high grade infill drilling, we are looking forward to continued drilling success at Crescent after our first six months of drilling efforts. Refer to original press release for complete assays.

“Just yesterday we announced outstanding new drill results at our Cosalá operations in Mexico. Combined, the tremendous exploration success being realized across our U.S. and Mexican operations in 2026 is a demonstration of the significant value that can be realized through systematic exploration and disciplined capital allocation. I am very excited about the future as we continue to execute on our multi-asset growth strategy at Americas Gold and Silver.”

The 88 reported drillholes between the Galena and Coeur Mines continue to infill past discoveries such as the 43L-TJ, 117 and 9 Veins as well as deliver a new high-grade vein discovery on the 49 level of the mine. The 9 vein is a particularly exciting development for the company, as it was originally discovered in Q3 2026, after being crosscut by a utilities drift being developed for mine services in an area with no historical drilling or vein projections. The Galena team has since completed roughly 85 metres of successful drifting along the strike of the vein and has established multiple drill bays to allow for drilling up and down dip of the original discovery to better define the scale potential.

“At the Coeur Mine, the 520 vein continues to exhibit exceptional growth potential with hole C034-188 expanding the zone an additional 45 meters up-dip of C034-166, with the combined vein now measuring 200m long by 200m high and remaining open for further expansion.

At the Crescent Mine, The company has completed 45 surface and underground core holes, with 12 holes being reported and 33 drillholes still pending final assays. The focus of the 2026 infill drill campaign at Crescent is to confirm high-grade ore shoots hosted within the historically mined Alhambra and South Veins to support ongoing mine planning followed by an updated Mineral Resource Estimate in 2027. Drilling to-date has confirmed historical vein projections as well as identified two new veins in the vicinity of the Alhambra vein. These new veins were intersected by holes SF-002 & SF-003 and SF-014 & SF-017 and warrant additional follow-up drilling to better define potential scale and grade of these promising new vein intercepts.

Americas Gold and Silver owns a portfolio of high-grade mining assets in the United States and Mexico and is executing a strategy to become one of North America’s leading silver producers while establishing a secure domestic supply of antimony.

The company’s flagship Galena Complex in Idaho is one of the United States’ premier silver mining districts and includes the nation’s largest antimony mine. Nearby, the fully permitted Crescent Silver Mine hosts one of the world’s highest-grade silver resources and offers significant future growth potential through shared infrastructure and processing.

Through a 51/49 joint venture, the company is developing a fully integrated domestic antimony supply chain-from mine to finished product-to help strengthen America’s critical mineral independence.

Americas also owns and operates the Cosalá Operations in Sinaloa, Mexico, where EC120, a high-grade silver-copper mine, is currently scaling production.
