U. S. Antimony Reports Doubling of Mexican Smelter Capacity

Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported a doubling of its Madero, Coahuila, Mexican smelter capacity with the startup of the No. 2 long rotary furnace (LRF). This is expected to double Mexican production by the end of Q2 due to the increased output of the Wadley and Guadalupe Mines. During Q1 of 2019, the Mexican production per month was approximately 69,000 pounds. For future production increases, there are four more LRFs at Madero, and construction has begun on the No. 3 LRF.

The five acre cyanide leach pond at the Puerto Blanco mill for the Los Juarez gold, silver, and antimony mine has been excavated and a culvert has been placed in it to divert storm water from running into the pond. The pond is now ready for the HDPE liner which will be the last major expenditure. The wiring, tailings pipe lines, and screens have been finished. Testing and startup of the plant is anticipated during Q2 2019.

Estimated production for April 2019 was as follows:

Antimony pounds171,726
Zeolite short tons1,172

Inventories of Mexican antimony mine ore continue to grow. The average Rotterdam price for antimony metal during April 2019 was $7,246.25 per metric ton or $3.287 per pound. Bear River Zeolite sales continue strong.

CEO John Lawrence said “The startup of the No. 2 LRF will liquidate the prepaid inventory of mine ore to help fund the Los Juarez gold, silver and antimony property leach plant and provide operating funds.”
