THOMPSON FALLS, MT / ACCESSWIRE / October 4, 2017 / United States Antimony Corporation (“USAC,” NYSE American: UAMY) reported plans to increase Mexican mine production at three of its four mines in the next 30 days. USAC production is in a “sold out condition” and additional raw material is needed for the USAC smelter at Madero, Coahuila, Mexico.
In San Luis Potosi at the Wadley Mine, the gravity mill will be started on lower grade ore that has accrued during the mining of direct shipping ore (DSO) for the smelter. Typically, this ore will make a 35-45% antimony concentrate that is also shipped to Madero. This could increase production by 25-50% at the Wadley mine. In Queretaro, the Soyatal District mines are awaiting new powder magazines to start production of DSO and mill feed for the mill at Puerto Blanco. Grades similar to the Wadley are expected. In Zacatecas, the Guadalupe Mines access road will be repaired and mining will be resumed at the Santa Monica mine for DSO and mill feed for the Puerto Blanco flotation and gravity mill circuits.
In Queretaro, a fourth mine, the Los Juarez gold/silver/antimony mine, awaits a permit from SEMARNAT (Mexican equivalent of the EPA) for the cyanide circuit at the Puerto Blanco mill, which is in the final stages of approval.
