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 PROGRESS ON THE BENEFICIATION OF LOS JUAREZ GOLD SILVER ANTIMONY PROPERTY IN MEXICO

January 7, 2019. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE American “UAMY”) reported the status of the beneficiation of the Los Juarez ore as follows:

1.    Approximately 30,000 tons of ore has been mined and is ready for processing

2.    The crusher and flotation circuits at the Puerto Blanco mill are ready for production

3.    The tailings pond excavation has been completed and will be ready for a liner following the installation of a culvert to divert storm-water inflow.

4.    The majority of the cyanide leach plant has been built and is being installed at Puerto Blanco.

5.    The caustic leach plant at Madero to process the flotation concentrates is operational and has recovered the precious metals with close to a 100% recovery. The initial metallic product from 6 runs was as follows:

6.    Marketing of the product is now underway. This will dictate whether USAC will further refine it to dore.

7.    Laboratory equipment is being purchased and personnel are being trained to fire assay and control the cyanide and other parameters.

8.    The cost of reagents and fluxes is being researched, and it appears that  China may be the best source

Wadley continues to be a major source of high- grade antimony ore. Load haul dump (LHD) equipment is being provided to speed up underground transportation and mine development.

The dismantling, removal  and transportation of the Great Lakes Chemical Corporation, LANXESS Holding Company US Inc. antimony plant in Reynosa, Mexico is on schedule to be completed by the end of January 2019. Trucking of the five large furnaces is underway, and they will increase the plant capacity at Madero for the production of crude oxide tremendously. This will accommodate more production from Wadley and Guadalupe in 2019.

The production of antimony, gold, and silver during 2018 was impacted by a reduction of the North American supply of raw materials from 70 loads in 2017 to 37 loads in 2018, a decrease of 47.1%. Each load contained about 18,000 pounds of antimony. However by Q4 2018, a sharp increase in the supply of Mexican production offset the reduction of the supply from North America.

The sale of zeolite increased from 12,377 tons in 2017 to 15,002 tons in 2018, an increase of 21%.

CEO John Lawrence said “We are excited about starting pilot production of gold, silver, and antimony from the the Los Juarez deposit in Q1 2019.”
