DALLAS, TX / ACCESS Newswire / September 24, 2025 / United States Antimony Corporation ("USAC," "U.S. Antimony," or the "Company") (NYSE American:UAMY)(NYSE Texas:UAMY), operating the only two antimony smelters in North America, announced that it will host Montana Governor Greg Gianforte and Director of Commerce, Marta Bertoglio, along with other state officials, at the Company's Thompson Falls, Montana antimony processing facility. The groundbreaking ceremony to be held tomorrow, September 25, 2025, is to kick off its expansion project which is already underway.

The groundbreaking ceremony tomorrow is also the site of USAC's Stibnite Hill Antimony Mine. USAC recently revived the development of this mine, which it has held and maintained the significant mineral rights to for many years. While this event is a groundbreaking by name, the project expansion has been underway with engineering completed and building construction underway for a number of months. USAC is scheduled for the project to be in production by the beginning of 2026.

The event is not only to commemorate the expansion of USAC's Thompson Falls, Montana operating facility, which will increase current processing capacity by over 400% and includes the capability of processing MIL SPEC antimony trisulfide production, but will also celebrate USAC's nearly 57 years in business. Governor Gianforte will address attendees on the significance of USAC's presence as a long-standing Montana corporation, the importance of strengthening both state and federal support of U.S. companies and their critical role in a strong and stable domestic supply chain that ensures U.S. defense, energy, and technology that originates from within USA.

"Hosting Montana's Governor and other state officials at the groundbreaking of our expansion project is another exciting culmination of several aligned forces and key decision-making in a series of critical moments," said Gary C. Evans, Chairman & CEO of United States Antimony Corporation. "This significant expansion, along with new innovations being implemented, underscores USAC's ability to move swiftly in an effort to respond to shifts and demands for not only our industrial customers, but now our U.S. Military (see Press Release dated September 23, 2025).

Jeff Fink, Project Manager and Vice President at USAC, further commented on the expansion, "When the decision was made by management and our board to significantly expand our processing capability here at Thompson Falls, I was asked to spearhead this effort. We engaged a well-established engineering firm to lead us through the necessary permitting and design of the project, knowing we had a limited footprint and a tight time frame for completion. At the same time, we did not want to disrupt our existing smeltering activity in any way. Thus far, we continue on our planned schedule with approximately 40% of the project now completed."
