:: U.S. Antimony Increases Mill Capacity by 50%

 

United States Antimony Corporation reported the start up of an antimony oxide mineral circuit at its Puerto Blanco antimony flotation mill located in Guanajuato, Mexico which increases its milling capacity from 150 tons per day to 225 tons per day. With the exception of USACís Los Juarez property, most antimony properties in Mexico contain oxide or mixed oxide-sulfide minerals. The sulfide minerals are recovered by flotation, but the oxide minerals must be recovered by gravimetric methods.

The Guadalupe, Guadalupana, and Soyatal properties contain large tonnages of oxidized dump material that are currently being fed to the oxide circuit. USAC has an option to purchase Guadalupe and is currently exercising its option to purchase Soyatal, the third largest producer of antimony in Mexico during World War II.

U.S. Antimony Corporation is a rapidly growing and vertically integrated producer of antimony-silver-gold from its Los Juarez property and other properties in Mexico and around the world, and zeolite from Idaho.
