Mojave Project Reveals Expanded Antimony & REE Targets for Locksley Resources
Locksley Resources (ASX: LKY / OTCQB: LKYRF) has confirmed multiple mineralised trends at its strategically positioned Mojave Critical Minerals Project in California, following specialised structural mapping that has significantly expanded the exploration footprint at both its antimony and rare earth element (REE) prospects.
New Structural Mapping Unlocks Expanded Mineral Potential
Recent structural geology mapping completed in June 2025 has delivered crucial insights at the Desert Antimony Mine (DAM) and El Campo prospects, transforming Locksley's understanding of the mineralisation potential at both sites.
At the Desert Antimony Mine, mapping has confirmed:
- Up to three discrete vein positions within a NNE-SSW trending mineralised corridor
- Stibnite veining extending 200 meters along strike at surface
- Quartz-carbonate veins up to 1 meter wide hosting antimony-rich stringer veins
- Previously unidentified E-W trending secondary mineralisation, creating potential for interconnected vein networks
Meanwhile, at the El Campo REE prospect:
- Confirmation of a steep 70-80° SW dipping REE hosting shear that increases mineralisation potential within Locksley's claims
- Evidence that historical trenching likely under-sampled the main shear horizon, suggesting high-grade REE zones remain untested
- Identification of the E-W trending South Fault as a new exploration target for REEs
These discoveries have led to the development of detailed 3D geological models for both prospects, enabling refined drill targeting and supporting the definition of JORC Exploration Targets.
Strategic Expansion of Drilling Program
Based on these encouraging results, Locksley is expanding its drilling program at the Desert Antimony Mine:
- New Plan of Operations to be submitted to the Bureau of Land Management in late July
- Regulatory approval expected by early September
- Expanded RC drilling program scheduled for Q3 2025
- Drilling will target both antimony and REE prospects, including the newly identified South Fault at El Campo
"The structural mapping program has significantly advanced our understanding of both the Desert Antimony and El Campo prospects, confirming the mineralised trends we are targeting and provided us with a solid geology model which is being used to refine our drill targeting. These results support our strategy to rapidly unlock the critical minerals potential of the Mojave project updates for Locksley Resources Ltd at a time when U.S. government support for domestic supply chains is accelerating."
— Julian Woodcock, Technical Director, Locksley Resources
Understanding Antimony: A Critical Defense and Technology Metal
Antimony is classified as a critical mineral by the U.S. government due to its essential applications in defense, technology, and industrial sectors. This brittle, silvery-white metalloid is primarily used in flame retardants, lead-acid batteries, and as a hardening agent in lead alloys for ammunition and bearings.
What makes antimony particularly important to investors is its supply vulnerability – China currently controls approximately 53% of global production, with Russia accounting for another significant portion. The United States currently has no domestic antimony production despite its designation as essential for national security.
High-grade antimony deposits like Locksley's Desert Antimony Mine (with surface samples grading up to 46% Sb) represent rare opportunities to establish domestic supply of this strategic metal, especially as geopolitical tensions increase the urgency for secure supply chains.
Strategic Positioning in U.S. Critical Minerals Supply Chain
The strategic significance of Locksley's Mojave Project has been further validated by Apple's recent $500 million investment into MP Materials to secure domestically produced rare earth magnets. This major investment underscores the growing corporate and government commitment to establishing secure domestic supply chains for critical minerals.
Locksley's project is ideally positioned in this emerging ecosystem:
- Located just 1.4km from MP Materials' Mountain Pass operation – the only producing rare earth mine in the United States
- Hosting both rare earth elements and antimony – two minerals designated as critical by the U.S. government
- Situated in California, providing access to excellent infrastructure and proximity to technology manufacturing hubs
Investment Thesis: Multiple Catalysts in a Critical Minerals Hotspot
Locksley Resources represents a compelling investment opportunity in the critical minerals sector for several key reasons:
| Key Strength | Details |
|---|---|
| Strategic Location | Directly adjacent to America's only rare earth mine in a region attracting major tech investment |
| Dual Critical Mineral Focus | Targeting both antimony (no U.S. production) and rare earth elements in one project |
| Expanded Target Footprint | Recent mapping has confirmed multiple mineralised trends and new exploration targets |
| Near-term Drilling Catalysts | Expanded drilling program scheduled for Q3 2025 |
| Strong Government Support | Positioned to benefit from U.S. initiatives to secure domestic critical mineral supply |
The company's dual focus on antimony (currently with no U.S. production) and rare earth elements places it at the intersection of defense, technology, and clean energy supply chains – all sectors receiving significant government and corporate investment.
Why Investors Should Follow Locksley Resources
Locksley Resources offers exposure to America's critical minerals renaissance at a time when securing domestic supply of these materials has become a national priority.
