Locksley Resources Limited Confirms High-Grade Rare Earth Mineralization At El Campo and Extends Dam Antimony Mineralization Locksley Resources Limited announced that assay reports from its maiden diamond drilling program at the El Campo Rare Element (REE) prospect, within the company's Mojave Prospect in California, confirmed high-grade NdPr-enriched light rare earth mineralization. The El Campo project is strategically located approximately 3.4 miles southeast of MP Materials' Mountain Pass Mine, the only operating and producing rare earth mine in the U.S. Neodymium (Nd) and Praseodymium (Pr) magnet rare earth oxides represent approximately 25% of TREO in key drill intercepts, highlighting enrichment in the critical rare earths elements required for permanent magnets, defense technologies, robotics and advanced manufacturing. Significant total REE oxide (TREO) intercepts returned from maiden drilling at El Campo include: Peak value of 6.03% TREO over 0.7m in drill hole ECDD0002; 7.2m @ 2.93% TREO in drill hole ECDD0002, including 3.75m @4.45% TREO; 0.90m @ 1.09% TREO in drill hole ECDD0004. In addition, final results from drilling at the company's Dam Antimony Mine (DAM) successfully intersected antimony mineralization beneath historical underground workings. Antimony intersections returned from the final two of eight completed drill holes including: Peak value of 6.44% Sb over 0.3m in DADD0007; 0.3m @ 2.90% Sb in hole DADD0007. The results at El Campo are significant given the strategic importance of Nd and Pr rare earth oxides in permanent magnet supply chains, including electric vehicles, robotics, unmanned systems, defense applications and advanced manufacturing.

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.
