Americas Gold and Silver Partners with Lot Sixteen to Advance Engagement with the U.S. Government on Antimony Processing Initiatives for Its Currently Producing Antimony Mine, Galena

Americas Gold and Silver Corporation (NYSE American: USAS) (TSX: USA) ("Americas" or the "Company"), currently the only antimony producer in the United States and a growing North American precious metals producer, is pleased to announce it has engaged Lot Sixteen, a D.C.-based government relations and communications firm, to initiate discussions with the U.S. Government regarding support for Americas' antimony production and the construction of a dedicated antimony processing plant in Idaho's Silver Valley. Americas operates the 100%-owned Galena mine complex in the Silver Valley of Idaho where it produces silver-lead-copper-antimony concentrate. Galena is currently the only producing antimony mine in the United States and has been producing antimony for over 80 years.

To strengthen its engagement with the federal government, the Company has signed an agreement with Lot Sixteen LLC, a consultancy with extensive experience advancing domestic critical minerals projects, advising on natural resource issues, and securing federal funding for its clients. Lot Sixteen will support Americas work to advance antimony processing in Idaho's Silver Valley.

Galena is the only producing antimony mine in the United States. The Company aims to deliver a secure and reliable source of antimony, a federally-recognized critical mineral with key applications in the defense, energy, and manufacturing sectors to the United States Government. Given its significant advantage of current production, Americas is evaluating the potential for construction of a new antimony processing facility to process Galena's current antimony production and, if capacity permits, could accept feed from other sources with the objective of creating a domestic hub for antimony production in the Idaho's Silver Valley.

Paul Andre Huet, Chairman and CEO, commented: "Americas Gold and Silver's Galena Mine in Idaho is already the sole and largest antimony producer in the United States. Our Galena mine has been producing significant amounts of antimony since the 1940's, and our test work this year has clearly reconfirmed the viability of extracting saleable antimony products from tetrahedrite concentrates currently produced.

"We are currently underway with the design of a new antimony processing facility for our Galena concentrate and are very pleased to engage Lot Sixteen to assist in our ongoing discussions with the United States Government. With the strong support of government and industry stakeholders, we believe Idaho can become the centerpiece of a resilient domestic supply chain for this critical metal."
