Locksley Resources Limited (ASX:LKY) (“Locksley” or “the Company”) is pleased to announce high-grade antimony grades up to 46% Sb from the recent rock chip sampling program. Eighteen (18) rock chips returned grades in excess of 1.4% Sb with eight (8) returning grades over 17% Sb. Since mid-2023, Locksley Resources has completed four surface sampling programs, mainly focused on detecting rare earth minerals at the Mojave Project, CA, located 45 minutes from Las Vegas. The most recent surface sampling program focused on the Desert Antimony Mine and potential for high-grade antimony mineralisation to be present along strike of the historically mined mineralised structures in an east-west and north-south direction. The sampling program revealed polymetallic mineralisation along strike of the mineralised structures suggesting a zoned reduced intrusive related system (RIRS).
Highlights:
- Extremely high-grade rock chip assays up to 46% antimony received
- 8 rock chip assays returned values over 17% antimony with over 18 of the returned assays over 1.4% antimony
- High-grade antimony is represented by historic workings developed on the quartz-calcite-stibnite veins
- Drill targeting and drilling approval application being prepared for submission to the Bureau of Land Management, alongside the Plan of Operations & Environmental Assessment Plan
- Antimony is listed as a critical mineral by the U.S. Department of Interior as it is used in a wide variety of military, energy, industrial and consumer applications
- U.S. has very limited domestic mined sources of Antimony and China has restricted export of antimony
- Funding opportunities for exploration through the Department of Défense (DoD) is being investigated with the next solicitation for funding through the Défense Industrial Base Consortium (DIBC) being considered

The Company is preparing drilling targets post receiving the recent high-grade antimony results and has commenced work to submit a drilling approval application to the U.S. Bureau of Land Management, which includes a comprehensive Plan of Operations and Environmental Assessment Plan. As antimony is designated a critical mineral by the U.S. Department of Interior, due to its widespread use in military, energy, industrial, and consumer sectors, domestic supply is crucial for national security and economic stability. With China recently restricting global exports, the U.S. faces a significant supply gap, highlighting the importance Locksley’s antimony asset could play if it can be commercialised. The Company is exploring funding opportunities through the Department of Defense, with particular interest in the next Defense Industrial Base Consortium (DIBC) solicitation to support the advancement of the Mojave Desert Antimony project.
Locksley Resources Limited Managing Director, Steve Woodham commented:
“The high-grade results from the follow-up sampling around the Desert Antimony Mine have exceeded expectations and highlights how well mineralised the property is, and not just for REEs. The surface strike length based on the recent high-grade results looks to be over 400m which has us very encouraged and looking forward to commencing a drill program post receiving the necessary approvals”.
We certainly look forward to sharing the outcomes of this review and unlocking value for our shareholders.”
