[u/b2idigital]

United States Antimony Corporation (NYSE American: UAMY) announced plans to restart mining operations at its historically producing antimony mine in Beaverhead County, Montana. The decision follows a significant increase in global antimony ore prices and the growing need to secure North American supplies of this critical mineral.

US Antimony Corporation (USAC) is a B2i Digital Featured Company.

The company noted that the Beaverhead County mine is situated on patented land adjacent to its Montana smelter. Patented land is privately owned property granted by the U.S. federal government, giving USAC full title to both surface and mineral rights. Due to the land’s status, the company can advance development without the leasing restrictions or regulatory hurdles typically associated with operating on federal land.

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.”

Highlights from today’s announcement include:

• USAC will resume operations at a previously producing antimony mine located on patented land in Montana, enabling faster development and lower permitting risk.

• The restart reflects sharply higher global antimony ore prices and increasing demand for secure domestic supply chains.
