• Development planning underway for extraction, financing, permitting, and pilot plant
• Expressions of Interest initiated with U.S. engineering contractors to commence extraction
• Underground access assessment confirms structural stability, supporting safe re-entry and development

Locksley Resources Ltd (ASX: LKY) has announced advancements with its U.S. Mine-to-Market strategy for antimony production. The company has delivered numerous key technical milestones, including a LiDAR underground survey, metallurgical processing updates, a bulk sample, underground workings assessment, and a maiden Exploration Target (JORC 2012). These milestones have provided Locksley with the confidence to fast-track the redevelopment plans and initiate extraction studies of mineralisation at the Desert Antimony Mine (DAM) Prospect. The company has advanced planning for a targeted, integrated work plan designed to fast-track extraction of mineralisation for Locksley's Phase 1 pilot processing facility, planned for 2026. The geological targeting at DAM, using the underground LiDAR survey and surface mapping and sampling, has enabled the company to establish an Exploration Target containing between 19,400 to 67,700 tonnes of antimony metal. The recently completed 325 kg bulk sampling has delivered a head grade ranging from 7.6% to 7.8% Sb, and flotation testwork has commenced to produce a premium antimony concentrate. The initial underground assessment indicates the structural stability and accessibility of the workings, providing a potential plan for future re-entry and development. Locksley is building a fully integrated mine-to-market platform aligned with American industrial, defence, and energy sectors, supporting U.S. objectives to rebuild domestic sources of defence-essential materials.

Locksley is focused on further enhancing its understanding of the DAM prospect and working in parallel with the U.S. government on permitting, finance, and ultimately physically delivering antimony product into the U.S. market.
