UAMY and Americas Gold & Silver: Launching North America’s First Commercial-Scale Hydromet Facility

Joint Venture with 49% Ownership and Exclusive Technology Sets a New Benchmark

United States Antimony Corporation (NYSE: UAMY) has unveiled a major joint venture with Americas Gold and Silver Corporation (Americas) to construct a state-of-the-art hydromet processing facility in Idaho. The facility, the first of its kind on a commercial scale in North America, is a strategic leap for both companies and the domestic critical minerals supply chain.

The new joint venture is structured with 51% owned by Americas and 49% by US Antimony, with UAMY in the role of managing member. Both partners will have equal representation on decision-making committees, enabling balanced strategic oversight.

Fast-Track Development Thanks to Completed Major Permitting

Unlike many new industrial projects facing years of regulatory delays, this facility is set to break ground rapidly. The Idaho property already has key environmental and operational permits in place, including:

The main remaining hurdle is construction permitting, which is expected to proceed quickly. This head start not only shortens ramp-up timelines but also positions the JV to meet growing U.S. demand for domestically processed antimony, copper, and silver far ahead of competitors.

Strategic Impact: Strengthening Domestic Critical Mineral Supply Chains

With the joint venture, UAMY and Americas aim to enhance control and cost-efficiency in processing three critical minerals—antimony, copper, and silver—produced by Americas’ Idaho mines. UAMY brings exclusive hydromet technology to the table and its status as the only integrated antimony company outside China and Russia.

Americas, fresh off acquiring full ownership of the Galena Complex (now the U.S.’s largest antimony mine), will capture value both from mining and downstream processing. In 2025, the Galena Complex alone produced 561,000 pounds of antimony contained in concentrate, underpinning ambitious growth plans as the facility comes online.

Facility Economics: Profit-Sharing and Market Expansion

The JV’s economics mean that Americas receives market rates for its mined antimony while benefiting from 51% of facility profit—a significant departure from previous models where value was lost in offtake deals. UAMY, as the manager and 49% owner, leverages its technical expertise and broad market connections to unlock downstream efficiencies and margins. This fully integrated solution—from mining to finished product—all within the U.S., is now within reach for a mineral considered key for defense, energy, and supply chain security.

Industry Implications: A Timely U.S. Response to Global Critical Minerals Race

This joint venture arrives as the U.S. government and industrial users intensify their search for domestic sources of critical minerals, often cited as national security interests. With permitting hurdles overcome and government grant paperwork underway, both management teams expect the plant will be a model for future industry collaborations. There are plans to seek federal funding aligned with national critical minerals objectives.

Takeaway: A Pivot Point for UAMY and U.S. Critical Mineral Security

For investors and industry observers, this venture signals a shift from concept to near-term execution in North American mineral processing. UAMY, leveraging unique processing technology and a first-mover advantage, positions itself at the heart of a domestic critical minerals revolution. Close monitoring of progress on construction and subsequent production volume will be key for anyone following UAMY’s next chapter—and the broader U.S. minerals sector.
