United States Antimony Corporation is a diversified minerals company that processes antimony ore into high-purity finished products including antimony trioxide (used as a flame retardant), antimony metal ingots (used in bearings and batteries), and antimony trisulfide (used in ammunition), serving U.S. and Canadian industrial, defense, and commercial customers. The company operates as the only fully vertically integrated antimony processor in the United States, with processing facilities in Mexico and a resumed domestic mining operation, and also recovers precious metals as byproducts and operates a zeolite mining and processing subsidiary for water filtration and environmental remediation applications. Revenue is generated through direct sales of antimony products at market-based pricing, long-term contracts with government and industrial customers, and royalty-based revenues from zeolite operations, with antimony designated as a critical mineral by the U.S. Government.
