Xtra Energy tests Nevada antimony ore to boost U.S. domestic supply for defense and tech, reducing reliance on China.

American Antimony Corp., now Xtra Energy Corp., has partnered with Silver Opportunity Partners to test antimony ore from its Nevada project, aiming to assess its suitability for integration into existing silver processing systems. The tests will evaluate harmful elements, reagent use, and processing compatibility, supporting U.S. efforts to build domestic supply chains for antimony—a critical mineral essential for defense, semiconductors, and energy storage. The move addresses supply risks from overreliance on China and supports national security goals. The company notes risks related to funding and project execution.
