About United States Antimony Corporation

United States Antimony Corporation (USAC) is a publicly traded natural resource company focused on increasing its raw material supply of antimony from global third parties and reactivating historical U.S. antimony deposits to secure a domestic supply chain. Operating since 1969, USAC is a fully integrated mining, transportation, milling, smelting, and selling company, with the only significant antimony smelter in the United States, currently in a 'sold out' condition. The company also owns Bear River Zeolite, Co., and aims to support the U.S. government in addressing supply constraints for critical minerals.
