United States Antimony Secures 150 Tons from 15x Expanded Bolivian Hydromet Plant
United States Antimony secured an exclusive contract to receive 150 tons of antimony flake from a Bolivian hydrometallurgical facility expanded 15-fold, with first shipments arriving February/March 2026. The company filed a $44 million DOE funding request to scale its proprietary hydromet technology and boost commercial output.
1. Processing Advancement
United States Antimony developed a proprietary hydrometallurgical process in collaboration with Bolivian partners, enabling efficient antimony extraction at commercial scale. The technology enhances recovery rates and lowers energy consumption compared with traditional smelting methods.
2. Bolivian Facility Expansion
A Bolivian plant underpinning this process has expanded its throughput capacity 15-fold, positioning it among the largest antimony producers globally. United States Antimony holds an exclusive contract to source all processed flake output from this facility.
3. Upcoming Deliveries
The first shipment of approximately 150 tons of antimony flake is scheduled for delivery to the company’s Thompson Falls smelter in February/March 2026. This volume marks a significant initial boost to United States Antimony’s inventory and sales pipeline.
4. DOE Funding Request
On January 15, 2026, United States Antimony submitted a $44 million funding proposal to the U.S. Department of Energy to support further scaling of its hydromet technology. Approval would accelerate plant upgrades and commercial deployment of the process.
