AMERICAS GOLD AND SILVER ANNOUNCES STRONG ANTIMONY PRODUCTION RESULTS AT ITS GALENA COMPLEX - THE ONLY PRODUCING ANTIMONY MINE IN THE UNITED STATES

Americas Gold and Silver Corp. obtained both antimony and copper production for the first three quarters of 2025, detailed in the attached table.

The year-to-date antimony output of 447,466 pounds, alongside 615,817 pounds of copper, underscores Galena's strategic critical metals importance, with a consistent Sb:Cu ratio averaging approximately 0.73 -- slightly above the historical 0.69-to-1 ratio resulting from previously announced testwork results (see Americas news release dated Sept. 8, 2025, for more discussion on recovered metals in flotation concentrate).

Paul Andre Huet, chairman and chief executive officer, commented: "Highlighting Galena as the only producing antimony mine in the United States, I am thrilled to announce both antimony and copper production from our Galena complex. Year to date we have produced 447,466 pounds of antimony and 615,817 pounds of copper.

"This is the first time under our new management that we are reporting antimony production, reflecting a new era where the antimony and copper from our tetrahedrite ore have the potential to drive significant future revenues.

"The antimony production announced today has been delivered while we make investments into several growth projects at Galena to set the stage for future near-term production growth. As we continue to execute this strategy to scale silver production materially by several multiples, potentially restoring historical production levels, we expect to concurrently increase antimony output. This is driven by our focus on increasing production of high-grade silver tetrahedrite ore, which is the primary host for antimony and copper at Galena. With our recently announced breakthrough of 99-per-cent-plus antimony extraction from flotation concentrate grading approximately 19-per-cent antimony, and the potential to realize on commercial recovery and marketable antimony products that can be produced using proven metallurgical processes, we are in a very strong position to be a major supplier of critical metals that the United States needs."

About ore at the Galena complex

The Galena complex primarily mines two types of ore from its underground veins in Idaho's Silver Valley: galena ore (a silver-lead ore) and tetrahedrite ore (a silver-copper-antimony ore). Galena ore, named after the mineral galena (PbS with silver inclusions), is the source of silver-lead concentrates and has historically dominated production with a historical output of over 240 million ounces of silver and 1.7 billion pounds of lead. Tetrahedrite ore contains the sulphosalt mineral tetrahedrite, which hosts approximately 1 per cent antimony along with copper and higher-grade silver compared with galena ore -- enabling silver-copper-antimony concentrates with a typical Sb:Cu ratio of approximately 0.69:1, as recently confirmed by testwork completed and announced on Sept. 8, 2025. This polymetallic tetrahedrite has been the subject of recent breakthroughs, such as 99-per-cent-plus antimony extraction from flotation concentrate grading approximately 19-per-cent antimony, positioning Galena as the only current U.S. antimony producer.

About Americas Gold and Silver Corp.

Americas Gold and Silver is a growing precious metals and antimony mining company with multiple assets in North America. In December, 2024, Americas increased its ownership in the Galena complex (Idaho, United States) from 60 per cent to 100 per cent in a transaction with Eric Sprott, solidifying its position as a growing silver and antimony producer. Americas also owns and operates the Cosala operations in Sinaloa, Mexico. Mr. Sprott is the company's largest shareholder, holding an approximate 20-per-cent interest. Americas has a proven and experienced management team led by Paul Huet, is fully financed to execute its growth plans, and focused on becoming one of the top North American silver and antimony mining companies.
