United States Antimony Corporation focuses on mining and processing antimony and precious metals in Montana and Mexico and zeolite in Idaho, and has expanded into new critical-mineral claims in Alaska, Montana and Canada. In 2025, antimony sales reached $35,380,271, up from $11,102,573 in 2024, driven largely by a higher average realized price of $25.12 per pound versus $7.61 a year earlier, amid a stronger Rotterdam market.
The company secured a five-year sole‑source IDIQ contract with the U.S. Defense Logistics Agency with a maximum value of $248 million for antimony metal ingots through September 2030, receiving delivery orders of about $12 million by early 2026. It also signed a five‑year industrial sales agreement for antimony trioxide and was awarded $27.0 million under the Defense Production Act to expand domestic antimony production.
US Antimony invested $37.2 million to acquire roughly 10% of Larvotto Resources Limited, extended a $2.5 million secured loan to an international antimony supplier, and entered a hydrometallurgical processing joint venture with Americas Gold and Silver Corporation. Customer concentration is high, with three customers providing 80% of 2025 revenue, and management disclosed material weaknesses in internal control over financial reporting as of December 31, 2025.
United States Antimony Corporation reported very strong 2025 growth but remained unprofitable. Revenue jumped 163% to $39.26 million, driving gross profit up 185% to $9.87 million and improving gross margin to 25% from 23%.
Higher operating expenses of $18.33 million, including $7.08 million of non‑cash share‑based compensation, led to a net loss of $4.34 million versus a $1.73 million loss in 2024. The company raised over $110 million from equity offerings and warrant exercises, ending 2025 with $91.3 million in cash and investments and funding $27.8 million of capital spending.
USAC highlighted $354 million of new antimony contracts, a roughly 10% equity stake in Larvotto Resources for $37.2 million, antimony inventories rising to 465 tons, and reiterated 2026 gross revenue guidance of $125 million, citing tight global antimony and tungsten markets as key tailwinds.

United States Antimony Corporation (US Antimony) has entered a new joint venture with Americas Gold and Silver Corporation to build and operate a state-of-the-art hydromet processing facility in Idaho.
The joint venture will be owned 51% by Americas and 49% by US Antimony, with US Antimony serving as the managing member and major decisions handled by a committee with equal representation from both partners. The plant will process copper, silver, and antimony from Americas’ adjacent mines, aiming for higher recoveries at significantly lower cost, which is expected to improve JV profitability.
The facility is described as the first commercial-scale hydromet processing center of its kind in North America, using technology for which UAMY holds an exclusive license. The Idaho site has already secured all key permits other than construction permits, allowing construction planning to begin. The partners also state they have prepared paperwork to seek potential U.S. government funding aligned with national critical mineral objectives.
