United States Antimony Corporation $(USAC)$ has announced an update on its procurement efforts for antimony supply, focusing on both international and domestic sources. The company operates two smelters, one in Thompson Falls, Montana, and another in Coahuila, Mexico. Despite facing a worldwide shortage of antimony, USAC is making progress with multiple parties and countries to secure new sources of quality raw ore. The company is also ramping up domestic supply from Alaska and Montana, which is expected to yield higher net margins. USAC has historically owned antimony mining properties in Mexico but halted operations in March 2024 due to financial constraints. The Madero Smelter in Mexico was restarted in April 2025, driven by increased international supplies and a significant rise in antimony prices. However, USAC has opted not to resume mining in Mexico, focusing instead on negotiations with international and Mexican companies for access to these mining assets. This strategy is bolstered by the company's unique position of owning a flotation facility and the only operating smelter in Mexico, providing leverage in negotiations over Mexican antimony deposits. Additionally, mapping and research by the U.S. Geological Service and the University of Alaska Fairbanks have identified potential antimony sources from historical mining operations in Alaska. These efforts align with USAC's expansion plans in Thompson Falls, Montana, and potential enlargement of its smelting capabilities at Madero, should foreign supplies continue to increase as anticipated. USAC remains the only vertically integrated antimony company outside of China, positioning itself to meet the growing demand from military and industrial customers.
