THOMPSON FALLS, MT / ACCESSWIRE / March 6, 2023 / United States Antimony Corporation (“UAMY”, “U.S. Antimony” or the “Company”) is pleased to announce that the Department of Defense (“DOD”) and the Defense Logistics Agency (“DLA”) have approved the third and final sample of antimony trisulfide supplied by the company. The samples were all taken from material obtained via concentrating feed from ore at the Sierra Guadalupe mines in the state of Zacatecas Mexico. The Company, in Q3 of 2022, entered into a purchase agreement for the ownership of the mining concessions at the Sierra Guadalupe Mines and is currently engaged in negotiations for the surface rights. The mines were worked prior to 1970 and the approved material came from concentrate made from dump rock generated from that mining effort.

The Guadalupe supplied a small amount of high-grade feed for direct smelting in 2016-2018 that had an average grade of approximately 32% antimony.


The mine, because of its predominance of sulfide ore, was acquired for the supply of ore to the Company’s Puerto Blanco flotation facility for concentration followed by shipment to the Montana facilities for synthesis into purified antimony trisulfide crystal.

This approval means that U.S. Antimony now has the only approved North American mine source of antimony for the production and supply of antimony trisulfide to the DOD/DLA for primers in munitions.
