TLDR:
- UAMY forms Idaho JV to expand U.S. antimony processing capacity
- New hydromet venture boosts UAMY critical minerals footprint
- UAMY partners with Americas to scale domestic antimony output
- Idaho JV positions UAMY in next phase of U.S. mineral supply
- UAMY expands processing reach through Americas partnership
United States Antimony Corporation traded near $8.30 after an early spike and midday stabilization. The move followed confirmation of a new processing joint venture in Idaho. Consequently, United States Antimony Corporation (UAMY) Stock: partners with Americas to expand antimony processing gained market attention.
United States Antimony Corporation, UAMY
The company joined Americas Gold and Silver to build a commercial hydromet processing facility. The plant will process antimony, copper, and silver from nearby mining operations. Therefore, the project targets greater domestic control of critical mineral refining.
Ownership assigns fifty-one percent to Americas and forty-nine percent to United States Antimony. United States Antimony will operate as the managing member of the venture. This structure balances operational authority with shared economic participation.
Joint venture structure targets critical mineral scale
The facility will sit on lands adjacent to active silver, copper, and antimony mines. The location reduces transport costs and supports integrated mineral handling. The design focuses on improving recovery efficiency and lowering processing expenses.
Management structured governance through an equal representation decision committee. Moreover, both companies retain voting power over major operational steps. This framework encourages alignment while protecting long-term partnership stability.
United States Antimony holds an exclusive North American license for the hydromet technology. The plant represents the first commercial-scale center of its type in the region. Consequently, the project positions the partners at the front of domestic antimony processing.
Permits secured while construction planning advances
The Idaho property already holds primary environmental and operational permits. Authorities approved discharge, stormwater, and dam safety certifications for the site. These approvals support rapid transition into the construction phase.
Construction permits remain pending but planning activities have already started. Engineering teams continue preparing timelines and infrastructure layouts. This progress shortens the expected path toward facility activation.
Americas produced over five hundred sixty-one thousand pounds of antimony in 2025. Existing mining output provides immediate feedstock for the new plant. The venture aligns production capacity with downstream processing expansion.
Strategic impact strengthens domestic mineral supply
The joint venture aims to improve recovery rates across three critical mineral streams. Lower processing costs could enhance profitability for both companies. The strategy reflects growing focus on domestic supply security.
United States Antimony remains one of the few integrated antimony processors outside China and Russia. The company operates facilities in North America supporting multiple industrial markets. This partnership extends that footprint into advanced hydromet refining.
The project supports broader expansion of U.S.-based mineral infrastructure. Both partners pursue growth in critical resource independence. As a result, the venture reinforces long-term positioning within the North American supply chain.
