Locksley Resources Ltd Achieves 99.5% Purity Antimony Trioxide Locksley Resources Ltd. announced it has achieved a significant metallurgical milestone with the successful production of 99.5% purity antimony trioxide from feedstock sourced from the Desert Antimony Mine at the Mojave Project in California. The result, achieved through the Company's metallurgical optimization program, demonstrated the potential to produce high-purity antimony products capable of helping supply strategic Western defense and industrial supply chains. Since antimony is classified as a critical mineral and the global supply is heavily concentrated in China, this achievement represents an important step in Locksley's strategy to help reestablish secure, 100% American made, antimony production and refining capability. Locksley is one of the few antimony-focused development projects in the US capable of directly controlling mining, processing and product specification. Demonstrating that feedstock from the Desert Antimony Mine can be upgraded to 99.5% purity antimony trioxide is a very significant achievement and validates the potential to produce high value refined, 100% American-made antimony products from their Mojave Project. This result reinforces the potential for their Mojave Project to play an important role in supporting future U.S. government and industrial demand for antimony. Antimony is essential for defense systems, munitions, electronics and advanced industrial applications. Achieving more than 99.5% purity antimony trioxide meets a key threshold for entry into specialized markets and enables a pathway for qualification with defense and strategic supply chain participants. The principal barrier to domestic antimony supply in the US is not ore availability, but the lack of US processing and refining capability.
