Locksley Resources Limited Announces High-Grade Antimony Intervals Intersected At the Desert Antimony Mine Locksley Resources Limited announced the maiden drill program at its Desert Antimony Mine confirmed high-grade antimony mineralization below the historical underground workings. Significant antimony intersections returned from six of the eight completed drill holes demonstrated: Peak value of 33.51% Sb over 0.4m inc 4.0m @ 4.87% Sb in hole DADD005A 2.0m @ w.69^ Sb in hole DADD0003 1.4m @ 5.62% in hole DADD0004. Drilling confirms continuity of high-grade surface stibnite mineralization along strike and below the historical underground workings supporting geological modelling and future drill targeting. Specific details on the drilling results can be found here: Antimony is designated as a critical mineral by the U.S. government, with limited current domestic production. The Desert Antimony Mine represents a rare opportunity to establish a primary, high-grade antimony source within the U.S. aligned with national security, defense and advanced materials supply chains.

Locksley Resources Commences Diamond Drilling At El Campo Rare Earth Prospect Part Of Its Mojave Project In California Locksley Resources announced it has commenced diamond drilling at the El Campo Rare Earth (REE) Prospect, part of its Mojave Project in California. The drilling program represents Locksley's first systematic drill testing of El Campo and is designed to evaluate the scale, continuity and geological characteristics of REE mineralization identified through historical work and recent surface sampling. The maiden program comprises four initial diamond drill holes targeting sheared carbonatite-hosted REE mineralization and will test the depth and lateral continuity of mineralization along 900m of strike, where previous surface sampling returned results of up to 12.1% TREO. El Campo is strategically located approximately four miles southeast of MP Materials' Mountain Pass REE Mine, a globally significant REE producer. The company is actively advancing the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley is executing a mine-to-market strategy for antimony, aimed at reestablishing domestic supply chains for critical materials, underpinned by strategic downstream technology partnerships with leading U.S. research institutions and industry partners. This targeted approach, combined with resource development with innovative processing and separation technologies, positions Locksley to play a role in advancing U.S. critical materials independence.

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. Locksley Resources Limited is focused on critical minerals in the United States of America. The Company is actively advancing the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley is executing a mine-to-market strategy for antimony, aimed at re-establishing domestic supply chains for critical materials, underpinned by strategic downstream technology partnerships with leading US research institutions and industry partners. This integrated approach combines resource development with innovative processing and separation technologies, positioning Locksley to play a key role in advancing US critical minerals independence.
