• Plan of Operations approval for upsized drilling program at Desert Antimony Mine
• Secured drill contractor for El Campo rare earths drilling in Q4
• LiDAR survey completed at Desert Antimony Mine to guide drill targeting and mine design
• Underground sampling program planned at Desert Antimony Mine to validate historical grades

Locksley Resources Ltd (ASX: LKY) has provided an update on its activities across the Mojave Critical Minerals Project in California. The company has received approval from the Bureau of Land Management (BLM) to expand the Plan of Operations for the Desert Antimony Mine (DAM), which will become effective upon completion of the bond payment. Locksley has also secured a drilling contractor for the upcoming exploration program planned for Q4 2025 at the El Campo rare earths project, where the drilling is designed to target the steeply dipping, structurally controlled mineralised horizon. Additionally, a comprehensive LiDAR survey of underground adits and stopes has been completed at the DAM, providing data to inform both program drilling design and future mine planning. The underground LiDAR survey will expand Locksley's knowledge of historic antimony production and provide a 3D wireframe model of the historic underground mine to assist with future drill targeting. Locksley also plans to commence a systematic underground sampling program at the DAM to further evaluate grade continuity and confirm historical production records. The company is also advancing broader exploration activities, including regional reconnaissance, claim-wide sampling, and evaluating various geophysical methods to evaluate its expanded land position.

Locksley is focused on advancing its fast-track mine-to-market strategy for U.S. antimony supply, with multiple parallel workstreams positioning the company to deliver near-term U.S. antimony supply into critical defense and energy supply chains.
