United States Antimony Corporation (USAC) NYSE (uamy) is a rapidly growing natural resource company that is increasing its raw material supply of antimony from properties in Mexico and third parties around the world. USAC has produced various antimony products since 1969 and is a fully integrated mining, transportation, milling, smelting, and selling company.  USAC operates the only significant antimony smelter in the United States and it is in a "sold out" condition. The Company has proven experience in underground and open pit mining, flotation and gravimetric milling, crushing and screening, dry grinding, cyanide leaching, precious metal refining, pyro-metallurgy, and marketing.

Operations include a smelter and a precious metal refinery in Montana, and a smelter and three mills in Mexico. Three Mexican properties supply direct shipping ore (DSO) or mill feed for the Mexican operations. The Los Juarez property and mill at Puerto Blanco are being permitted to start gold and silver production that will supplement the antimony values and identify the Company as a "precious metal producer." 

USAC owns 100% of the Bear River Zeolite, Corp. mine in southeast Idaho that management  regards as one of the best zeolite properties in the world due to its high cation exchange capacity, low sodium content, hardness,  uniformity, high potassium content, large surface area, and low clay and impurity content.

U. S. ANTIMONY REPORTS PLANS TO INCREASE MEXICAN MINE PRODUCTION

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.

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.
