United States Antimony Corp (NYSE American: UAMY) is a mineral processing company that mines, smelts, and sells antimony products, zeolite, and precious metals. Revenue comes from transactional sales of antimony oxide, antimony metal ingots, antimony trisulfide, zeolite in various grades, and refined and unrefined gold and silver. The company describes itself as the only U.S.-based domestic processor of antimony products and the only operator of a vertically integrated, permitted antimony smelter in the country, giving it a structural position for domestic customers requiring short processing and delivery times. Founded in January 1970 and headquartered in Montana, UAMY operates a processing facility in Sanders County, Montana, and two facilities through its USAMSA subsidiary in Mexico. In 2025, the company also initiated a bulk sampling program at its Stibnite Hill property in Montana, producing approximately 840 tons of antimony-bearing material, while sourcing ore from new suppliers for its Madero, Mexico facility. Net cash used in operating activities was $9.7 million in FY2025, driven by a $12.2 million increase in inventories. Gary C. Evans serves as Chairman and Chief Executive Officer.
