Locksley Resources partners with Hazen Research to revive U.S. antimony production, leveraging high-grade ore and domestic supply chain advancements.

Locksley Resources has partnered with Hazen Research to process antimony ore from its Mojave Desert project, a major step toward restarting U.S. antimony production. The collaboration will test recovery rates and refine processing methods, supporting the development of pilot and commercial plants. This follows the company’s creation of the first 100% American-made antimony ingot, proving a domestic mine-to-metal supply chain. The move responds to global supply disruptions, including China’s 2024 export restrictions that drove prices up. The project, located near the Mountain Pass rare earths mine, has shown high-grade results, including samples with 46% antimony and significant silver, and a 1.2-kilometer mineralized zone. Backed by a $191 million letter of interest from the U.S. Export-Import Bank and research partnerships, Locksley is advancing toward commercial production.
