U. S. ANTIMONY REPORTS START OF LOS JUAREZ PILOT PRODUCTION

June 5, 2017. Thompson Falls, Montana. United States Antimony Corporation (“USAC”, NYSE MKT “UAMY”) reported that approximately 400 metric tons of Los Juarez gold/silver/antimony rock has been trucked to the Puerto Blanco mill in Guanajuato, Mexico and milled. Initial results using X-ray are encouraging, but we are awaiting results by a third party lab. The permit for a cyanide leach circuit for the Puerto Blanco mill tailings has been reviewed by SEMARNAT (Mexican equivalent of EPA), and USAC is changing the location and design of the tailings pond to comply with their request..

Following are the sales estimates for May 2017:

Product / May 2017
Antimony pounds North America / 102,820
Antimony pounds Mexico / 64,578
Total antimony sales / 167,398
Zeolite tons / 1,152

Production from North America was effected by a maintenance shut down by a supplier that reduced its supply of antimony for May by about 60,000 pounds. However, Mexican sales increased from 44,092 pounds in April to 64,578 pounds in May, an increase of 20,486 pounds or 46%. Since the end of April 2017, the average Rotterdam price of Grade I antimony metal per metric ton has decreased from $8,850 ($4.014 per pound) to $8,800 ($3.991 per pound) by the end of May, a decrease of $0.023 per pound. Zeolite sales increased from 1,031 tons in April to 1,152 tons in May, an increase of 121 tons or 11.7%. The sale of silver and gold is being held until the end of Q2.

The Company has resumed its research on the production of antimony tri-sulfide

(“crudum” or “needle antimony”) that is used for primers in ordnance and friction brakes. It contains 70.5% antimony and sells for approximately $6.10 per pound. This price equates to approximately $8.65 per pound for the contained antimony.

The Company will be positing a Facebook page for United States Antimony and another for Bear River zeolite in the near future.

CEO John Lawrencesaid “We are anxiously awaiting assays from the milling of the Los Juarez gold, silver, and antimony pilot production. We will continue to increase Mexican antimony production and BRZ zeolite sales. These should provide increased cash flow to augment production.”
