Arizona Tribune - United States Antimony Corporation Executes Antimony Supply Agreement with New Industrial Customer for a Term of up to Five Years

DALLAS, TX / ACCESS Newswire / November 11, 2025 / United States Antimony Corporation ("USAC," "US Antimony," the "Company"), (NYSE American:UAMY)(NYSE Texas:UAMY), announced today, the execution of a new supply agreement with a U.S. industrial fabric manufacturer, for the purchase of antimony trioxide, a key ingredient in flame retardant materials that are essential to the customer's industrial fabrics business. This new contract reinforces both parties' commitment to supply security within the USA and to the adoption of USAC's increased production volumes beginning early next year.

Under the terms of the agreement, USAC will supply this customer, which wishes to remain anonymous, with antimony trioxide to meet stringent technical specifications. USAC's finished material was tested earlier this year to verify that these specifications can be met. The definitive contract term is five (5) years, with renewal up to five (5) additional years, for a value of up to $106.7 million in the first five year term.

This agreement reflects a deliberate move by a large U.S. industrial customer to anchor its critical supply chain within domestic borders. By sourcing antimony trioxide from USAC, the customer reduces exposure to international supply disruptions, shipping and certain out of market pricing volatility, and geopolitical dependencies. It signals a broader industrial policy trend toward reshoring critical mineral supply chains to reinforce both economic resilience and national security. For USAC, this contract represents a strategic commercial foothold with a high-volume, long-term and stable domestic customer, supporting the revitalization of U.S. manufacturing capacity and ensuring continuity of demand that strengthens both companies' operational stability.

This new relationship represents a key milestone in restoring and strengthening domestic industrial collaboration for USAC with a significant industrial customer. "We are proud to partner with a major U.S. manufacturer that shares our vision of an integrated, reliable, American supply chain," said United States Antimony Corporation Chairman and CEO, Gary C. Evans. "Coupled with our recently announced sole-source five-year contract with the Defense Logistics Agency (DLA) in the amount of $245 Million (see press release dated September 23, 2025), our Company's current contracted pipeline of orders exceeds $351 Million. No other antimony company can make this statement. We believe this new contract demonstrates the growing movement among U.S. suppliers and industrial companies to join forces in rebuilding and securing domestic supply chains to strengthen the backbone of American innovation and infrastructure."
