US Antimony to boost Mexico mine production

PRESS RELEASE

October 4, 2017. Thompson Falls, Montana. 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 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.

Following are the sales estimates for August 2017:

Product	September 2017
Antimony pounds	177,481
Zeolite tons	897
Silver ounces	8,334
Gold ounces	27.5

At the beginning of September 2017, the average Rotterdam price of Grade I antimony metal per metric ton was $8,450 ($3.833 per pound), and by the end of September, the price had decreased to $8,425 ($3.81 per pound) approximately 0.08%. Antimony sold during September was lower than August, because two customers totaling 54,894 pounds of contained antimony did not want delivery until the beginning of Q4 2017. The product had been made and is in inventory. Had it been delivered on time, the production would have been 232,345 pounds, compared to 215,740 pounds in August.

At the BRZ zeolite plant in Idaho the capacity has been increased significantly. New markets are being pursued and sales should be increasing.

CEO John Lawrence said "We are excited about the ramp up of Mexican mine production which should increase sales, reduce costs, and create better operating margins before the end of the year."
