Arizona Tribune - United States Antimony Announces Antimony Mining Operations in the State of Montana

DALLAS, TX / ACCESS Newswire / July 3, 2025 / United States Antimony Corporation ("USAC," "US Antimony," the "Company"), (NYSE American:UAMY), announced today that it has been stealthily reacquiring mining claims and real property since earlier this year, immediately adjacent to its existing antimony smelting operations located in Sanders County, Thompson Falls, Montana.

Mining operations at these properties were initiated back in the early 70's by prior management of the Company in and around our existing operating antimony smelter. The Company owns today approximately 24 acres of surface fee simple land and non-patented mining rights on approximately 1,200 acres.

After a thorough review of the geology, historical records, and actual "boots on the ground" observations in and around our existing operations, it was determined earlier this year that existing quantities of antimony, sufficient to re-establish profitable mining activities, could exist in the three vein systems on the property. Additionally, it was determined that surface mining operations with a minimal pre-development expenditure could possibly be feasible in addition to the prior underground mining operations that were previously utilized. The Company is permitted to begin immediate mining operations on the five acres of the patented property, having filed a Small Miners Exclusion Statement (SMES) with the State of Montana. We intend to file a second SMES within the next 10 days in addition to filing Exploration Permit applications with both the State of Montana (DEQ) and the US Forest Service. With the proximity of the only U.S. operating smelter next door, overall economics are obviously very attractive. Today the primary source of feedstock for this smelter is foreign. With the combination of Montana material now along with material from our Alaska antimony operating activities, our planned growth objectives become further insured.

Commenting on this announcement, Mr. Gary C. Evans, Chairman and CEO of USAC, stated, "The U.S. Government is continuing to get actively involved in securing North American supply chains of critical minerals, especially antimony. This is due to China's dominance and embargos initiated last year. Market rules do not apply to national security and China does not play fairly in the global free marketplace as we outlined in our Form 8-K dated June 27, 2025. Governments around the world are finally beginning to understand the need to secure their own supply chains, specifically for critical minerals. There continues to exist a worldwide shortage of this critical material necessary for our Department of Defense. The significant price increase experienced for worldwide supplies of antimony ore have made this decision to reopen our existing antimony mine adjacent to our smelting operations an easy one. With these mining claims combined with our over 35,000 plus acres of new mining claims located in Alaska, we are the first company to restart mining operations in the United States going back decades. Additionally, we are the first fully integrated antimony company in the world having our own antimony supply and controlling both our own midstream and downstream operations."
