• Batch sampling program completed at the Desert Antimony Mine (DAM)
• Assay results return exceptional high-grade antimony (Sb) values up to 26.1%
• Significant grade improvement over previous sampling, with weighted averages reaching up to 25.7% Sb
• Total mass of 287 kg collected for metallurgical testwork and pilot design

Locksley Resources Limited (ASX: LKY) has announced the results of a batch sampling program at the Desert Antimony Mine (DAM) deposit, part of the Mojave Project in California, USA. The batch sampling program was designed to further evaluate the high-grade antimony mineralisation at DAM, following the technical milestones achieved in late 2025, which included a 325kg sample and the production of a 68.1% Sb premium concentrate. The batch sampling program targeted specific mineralised vein material within the historical workings, with the results exceeding expectations. Batch 1 sampling returned a weighted average of 25.7% Sb, Batch 2 returned 21.3% Sb, and Batch 3 returned 11.4% Sb, for a total weighted average grade of all samples combined (287kg) of 18.7% Sb. These high-grade results present the opportunity for operational advantages, particularly regarding processing efficiency, as the high-grade nature of the DAM deposit potentially reduces the required mass-pull and energy consumption for grinding, leading to faster flotation kinetics and a smaller equipment footprint, which optimises capital expenditure for the planned 2026 pilot plant and enhances overall recovery rates. The 287kg of batch sample material will now undergo advanced flotation and crushing testwork to finalise the process flowsheet, and the data from this program will feed directly into the engineering design for the Phase 1 pilot processing facility.

With these results, the completion of pad preparation and other pre-drilling activities, added to the imminent arrival of the drill rig at Mojave, Locksley is entering a very exciting time as it advances toward U.S. antimony production.
