AMERICAS GOLD AND SILVER CONTINUES TRACK RECORD OF SIGNIFICANT DISCOVERIES AT THE GALENA COMPLEX WITH A NEW GALENA MINE VEIN DISCOVERY GRADING 1,062 G/T AG, 0.7% CU OVER 1.3 METERS WHILE CRESCENT DRILLING RETURNS 1,891 G/T AG, 0.3% CU OVER 1.3 METERS AND 1,560 G/T AG, 0.3% CU OVER 1.1 METERS

Americas Gold and Silver Corp. has released high-grade silver-copper-lead-antimony drill results from the company's largest-ever exploration and mineral resource conversion drilling program at the Galena complex, comprising the operating Galena mine, connected to the restart-stage Coeur mine and the neighbouring Crescent mine.

The assays reported today are a result of substantial infill and stepout 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 modelled 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 (see Americas Gold and Silver's news release dated March 30, 2026).

Paul Andre Huet, chairman and chief executive officer, 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 grams per tonne silver, 0.7 per cent copper and 0.6 per cent antimony) 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 0.4 m of 7,123 g/t Ag, 3.24 per cent Cu and 1.81 per cent 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 200 m along strike and 200 m 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. Drill holes SF-002 and SF-003 intersected 1.1 m of 1,109.5 g/t Ag, 0.3 per cent Cu and 0.8 m of 939.3 g/t Ag, 0.1 per cent 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.

"Just yesterday, we announced outstanding new drill results at our Cosala operations in Mexico (see news release dated Sept. 17, 2026). 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 multiasset growth strategy at Americas Gold and Silver."

The 88 reported drill holes 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 updip and downdip 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 metres updip of C034-166, with the combined vein now measuring 200 m long by 200 m 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 drill holes 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 continuing 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-003m SF-014 and SF-017 and warrant additional follow-up drilling to better define potential scale and grade of these promising new vein intercepts.
