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 ON LOS JUAREZ GOLD AND SILVER PLANT

HIGHLIGHTS: The Puerto Blanco mill for the Los Juarez gold, silver, and antimony deposit will start production testing during January 2020.

....................

January 6, 2020. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY) reported that production testing of the cyanide leach circuit at the Puerto Blanco mill in Guanajuato has begun. Security and transportation measures are being implemented.

The Los Juarez mineralization is disseminated in jasperoid pipes that are present over a strike length of 3.5 kilometers, up to 1 kilometer in width, and are believed to be continuous below 400 meters. The jasperoid is recognized visually, but the grade of the gold and silver are speculative and are best determined by milling. The antimony mineralization is visually recognized and generally is a signature of the precious metals. A global assay based on shallow drilling, sampling, and mill testing is 0.035 ounces of gold, 3.27 ounces of silver per metric ton and 0.65% antimony. The gold equivalent of the values is 2.6 grams. Sampling of different areas has disclosed gold greater than one ounce and silver up to 47 ounces per metric ton, and antimony up to 10%. The deposit is bulk mineable by open pit methods for years, and the grade is excellent for an open pit.
