Locksley Resources Achieves High-Grade Antimony Concentrate at Desert Mine Project

Locksley Resources, an Australian-based explorer, has recently revealed promising results from its metallurgical test program on surface samples collected from its Desert Antimony Mine Project located in California's Mojave Desert. The company reports that these tests have yielded exceptionally high-grade antimony concentrate, significantly surpassing the grades of comparable projects in the United States.

The initial results from these metallurgical tests indicate an impressive final flotation concentrate containing 68.1% antimony. This purity aligns closely with the technical maximum stibnite grade of 71.68%, with impurities remaining minimal—a crucial factor that not only exceeds marketable sales thresholds (which require a minimum of 55%), but also enhances the commercial viability of the concentrate.

Such high grades of antimony are increasingly in demand, especially by the U.S. government, which is prioritizing a fully domestic supply chain for critical minerals. Antimony, used extensively across various industries including munitions, semiconductors, and energy systems, has gained strategic importance amidst growing concerns over mineral security.

Reflecting this market shift, Locksley Resources has shown adaptability by aligning its operation strategies with U.S. governmental policies focused on securing essential resources domestically. The company aims to accelerate its pathways in the U.S. mineral landscape by implementing strategies that not only maximize both grade and recovery but also consider low environmental impact.

Future Plans and Partnerships

In addition to these promising results, Locksley is poised to take further steps in its operational journey. The company will be initiating the collection of a bulk sample from the underground workings to facilitate additional testwork, which aims to develop processes for the production of antimony ingots—an expansion of its product offerings.

Moreover, Locksley has forged a significant strategic collaboration with Rice University to develop DeepSolv™, a technology aimed at domestic processing of North American antimony. This partnership supports the broader framework of Locksley's U.S. Critical Minerals and Energy Resilience Strategy, which focuses on enhancing the
