Americas Gold and Silver drills 1,062 g/t Ag, 0.7% Cu over 1.3 m at Galena Complex; 1,891 g/t Ag over 1.3 m at Crescent

Toronto, Ontario--(Newsfile Corp. - September 18, 2026) - Americas Gold and Silver Corporation (TSX: USA) (NYSE American: USAS) ("Americas" or the "Company") a North American producer of silver and other critical minerals supporting artificial intelligence, electrification, national security and advanced manufacturing, is pleased to announce 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.

The assays reported today are a result of substantial infill and step-out exploration drilling conducted across multiple target areas at the Galena, Coeur (see Figure 1), and Crescent (see Figure 2) 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 (see Americas news release dated March 30, 2026).

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
