United States Antimony Corporation (NYSE: UAMY) is a specialty metals and mining company focused primarily on the production and sale of antimony and antimony-related products. The company’s operations encompass the extraction, processing and refining of antimony ore into metal and chemical forms, including antimony trioxide, antimony metal ingots and other oxide derivatives. In addition to its core antimony line, the company produces byproducts such as gold, silver and copper concentrates, reflecting an integrated approach to mineral extraction and resource recovery.
United States Antimony’s product portfolio serves critical industries ranging from flame retardants, lead–acid batteries and consumer electronics to specialty chemicals and petroleum catalysts. The company’s antimony trioxide is widely used as a synergist in halogenated flame retardants, while its metallic antimony finds applications in low-friction alloys and lead–acid battery grids. By leveraging in-house refining and smelting capabilities, United States Antimony maintains control over product quality and supply chain reliability, positioning itself as a nimble supplier in a market with high barriers to entry.
Founded in the mid-20th century, United States Antimony has evolved through strategic acquisitions and facility upgrades to become one of the few domestic producers of critical antimony compounds. The company operates open-pit and underground mining assets in Idaho, USA, and maintains a smelting and refining complex in South Texas. These geographically diverse sites enable United States Antimony to manage ore sourcing and processing with greater flexibility, while serving customers across North America, Europe and Asia.
Leadership at United States Antimony is helmed by Chief Executive Officer James T. Baldridge, who brings decades of metals and mining experience to the role. Under his guidance, the company has pursued operational enhancements and environmental stewardship initiatives aimed at modernizing its facilities and ensuring sustainable resource development. Supported by a management team with expertise in metallurgy, logistics and regulatory compliance, United States Antimony continues to focus on meeting global demand for antimony in advanced manufacturing and energy storage applications.
