Locksley Resources Advances U.S. Antimony Production with Successful Metallurgical Tests

What's Happening?

Locksley Resources Ltd has announced promising results from initial metallurgical testwork on samples from the Desert Antimony Mine Prospect. The tests, conducted by Independent Metallurgical Operations Pty Ltd, aimed to validate the Mojave Project's potential to support a domestic antimony supply chain. The testwork involved a 23.1 kg composite sample with a 9.6% antimony grade, processed at Base Metallurgical Laboratories in Tucson, Arizona. The flotation tests successfully recovered stibnite, the antimony-hosting mineral, producing a concentrate with over 30% antimony in five out of six tests. The results indicate the feasibility of producing high-grade antimony concentrate, aligning with U.S. priorities for critical mineral supply security.

Why It's Important?

The successful testwork marks a significant step towards establishing a domestic antimony supply chain in the U.S., reducing reliance on foreign sources. Antimony is a critical mineral used in various industries, including electronics and flame retardants. Locksley's progress supports U.S. government efforts to secure onshore mineral supplies, enhancing national security and economic stability. The ability to produce high-grade antimony concentrate domestically could benefit U.S. industries by ensuring a stable supply and potentially lowering costs associated with importation.

What's Next?

Locksley Resources plans to continue metallurgical testwork to improve stibnite recovery and concentrate grade. Future steps include regrind and cleaning tests, mineralogical analysis, and collaboration with Rice University for solvent extraction testwork. The company is also exploring options for pilot testing to produce antimony metal ingots and other derivatives. These efforts aim to refine the production process and establish a reliable supply chain for antimony in the U.S. market.
