Americas Gold drills 1.9 metres of 1,392 g/t silver at Galena mine, Idaho

Americas Gold and Silver Corp. [TSX: USA; NYSE American: USAS] has released additional exploration drilling results at the Galena complex, Idaho, marking its fourth major new discovery driving significant growth in the vicinity of the recently discovered 149 Vein complex.

Exploration diamond drilling from the 4300 level of the Galena mine, completed in Q1 2026, has defined up to six new high-grade silver-copper-antimony splays located approximately 150 metres southwest of the high-grade 149 vein. This area, known as the 43L-TJ vein complex, is composed of a series of silver-copper-antimony plus or minus lead veins, which have been discovered within 25 metres of current mine infrastructure. As a result, the Galena team is currently planning follow-up drilling as well as an exploration drift into the 43L-TJ vein area to better understand structural controls on mineralization and fast track future production from the 4300 level.

Paul Andre Huet, chairman and CEO, commented: “Our team at Galena continues to deliver impressive new discoveries at our flagship operation. The discovery of six new high-grade silver-copper-antimony veins at the 43L-TJ vein complex is advancing on a similar trajectory to our 034 vein discovery mid last year, which has already added material ounces to our 2025 resource update and is now in development to prepare for future production. These are the strengths of pairing an aggressive drill campaign, strong team and large exploration budget with the tremendous amount of infrastructure already in place at Galena, a world-class operation.

“This marks our fourth major new discovery and highlights four high-grade discoveries in just one year of drilling, underscoring the significant untapped potential across the Galena complex. Located just 25 metres from existing infrastructure, the 43L-TJ vein is wide open for expansion and will remain a focus of our team to aggressively advance this high-grade opportunity in 2026.

“Galena has a long and storied history of silver, copper, lead and antimony production, and this new discovery is a true testament to the outstanding growth potential of our Idaho assets, with grades that highlight the Galena complex as one of the highest-grade silver operations globally.”

The 43L-TJ vein complex was discovered while completing infill and stepout drilling targeting the 149 vein complex. The company has intersected significant grades in six core holes to date. Key intercepts from the campaign, reported with true widths, included 1.9 metres at 1,392 g/t silver, 1.9% lead, 1.5% copper and 1.5% antimony, 1.0 metre of 1.313 g/t silver, 2.6% lead,1.4% copper and 1.1% Sb, 0.7 metres at 2,563 g/t silver, 0.3% lead, 1.8% copper and 1.4% Sb, 1.7 metres at 832 g/t silver, 3.8% lead, 1.4% copper and 1.6% Sb, 0.9 metres at 470 g/t silver, 5.8% lead, 1.22% copper and 1.5% Sb, 0.5 metres at 3,714 g/t silver, 0.1% lead and 3.9% copper.

Americas Gold and Silver is a rapidly growing North American mining company producing silver, copper, lead and antimony from high-grade operations in the United States and Mexico. In December 2024, Americas acquired 100% ownership of the Galena complex (Idaho) in a transaction with Eric Sprott, former 40% Galena owner, becoming Americas’ largest shareholder.

This transaction consolidated Galena as a cornerstone U.S. silver asset and the nation’s largest antimony mine. In December 2025, Americas acquired the fully permitted, past-producing Crescent silver mine (nine miles from Galena) creating significant potential future synergies through shared infrastructure and processing. In February 2026, Americas formed a 51/49 joint venture with U.S. Antimony to build a new antimony processing hub at Galena, creating a U.S. mine-to-finished product antimony solution.

Americas also owns and operates the Cosala operations in Sinaloa, Mexico. Americas is fully financed to aggressively grow production at the Galena complex, Crescent and in Mexico with an aim to be a leading North American silver producer and a key source of U.S.-produced antimony.
