United States Antimony Corporation operates as a mining and minerals processing company focused on critical minerals. The company's business is divided into two primary segments: Antimony and Zeolite. Its antimony operations include mining and smelting facilities in Montana and Mexico, which produce antimony oxide, antimony metal, and antimony trisulfide. These products are essential components in flame retardants, storage batteries, and ordnance. The zeolite segment operates the Bear River Zeolite mine in Idaho, extracting industrial minerals used for water purification, agriculture, and environmental remediation. Additionally, the company recovers precious metals such as gold and silver from third-party ores at its Montana facility. By owning two of the few operating antimony smelters outside of China and Russia, the company maintains a strategic position in the North American critical minerals supply chain.
