From China's Export Ban To A Nevada Leach Pad: The Junior With a Domestic Solution to the US Antimony Supply Chain
Americas Gold and Silver’s Galena discoveries keep stacking up, adding high-grade silver-copper-antimony veins that reinforce its ID-based critical‑minerals hub.
The most recent Americas Gold and Silver announcement (April 30, 2026) reports the fourth major new discovery at the Galena Complex in Idaho in a single year. Dubbed the “43L‑TJ Vein Complex,” it comprises up to six new high‑grade silver‑copper‑antimony splay veins located just 150 meters southwest of the previously discovered 149 Vein and within 25 meters of existing mine infrastructure. Highlight intercepts include 1.9 m of 1,392 g/t Ag, 1.5% Cu and 1.5% Sb, as well as smaller intervals assaying up to 2,563 g/t Ag. The company intends to follow up with additional drilling and an exploration drift to fast‑track future production.
This is a positive development, but it is entirely in line with the narrative that Americas Gold and Silver has been delivering for more than a year. The Galena Complex has repeatedly generated high‑grade discoveries (10 new veins announced in March 2026, eight new splays in January 2026, the 149 Vein extension in August 2025). The 43L‑TJ Vein adds to that string, confirming that the system remains prolific and supports the aggressive 64,000‑m drill campaign for 2026. Because the market already prices in ongoing discovery success, this specific news does not fundamentally alter the near‑term production or resource outlook; it merely reinforces the thesis. No resource update, production restart, or permitting milestone was attached. The news is therefore routine but undeniably positive.
Americas Gold and Silver is a precious‑metals producer with its flagship Galena Complex in Idaho’s Silver Valley, where it mines high‑grade tetrahedrite ore containing silver, copper, antimony, and lead. The company also operates the Cosalá Mines in Sinaloa, Mexico, and recently acquired the Crescent Silver Mine adjacent to Galena. Galena is currently the only domestic primary antimony producer in the United States, a strategically critical position following China’s export ban. In 2025, the company produced 2.65 Moz silver, 561 klb antimony, and 797 klb copper, achieving a 52% year‑over‑year increase in silver output. Management is executing a turnaround focused on long‑hole stoping, shaft upgrades, and a mine‑to‑antimony‑product joint venture with United States Antimony.
