Locksley Resources Ltd
Locksley Resources (ASX: LKY) has unveiled significant geological breakthroughs at its Mojave Project in California, with underground mapping revealing a major new exploration target that could dramatically expand the company's critical minerals resource base. The discovery of the Beefeater Shear, a substantial 10-15 metre wide corridor, represents a potential game-changer for the company's critical minerals strategy.
The comprehensive Stage III technical review has provided crucial insights into the structural controls of high-grade antimony mineralisation. Furthermore, detailed underground mapping at the Desert Antimony Mine (DAM) has confirmed the geometry of mineralised veins and revealed how structural events have created discrete high-grade blocks that can now be systematically targeted.
The Beefeater Shear: A Major New Target Emerges
The identification of the Beefeater Shear represents the most significant development from Locksley's latest geological campaign. This North-South striking structure sits strategically between the proven high-grade DAM deposit and the Hendricks prospect. Consequently, this suggests the mineralised system may be far more extensive than previously understood.
Key characteristics of the Beefeater Shear include:
• Width: Up to 10-15 metres of shear zone corridor
• Structure: Broader zone of moderate shearing containing multiple intense, narrower shears
• Alteration: Intense goethite alteration – a diagnostic indicator of antimony-rich sulphide mineralisation
• Geological signature: Mirrors the structural timing and kinematic history of the high-grade DAM system
Management Insight
"The technical findings from this geological mapping campaign have significantly enhanced our exploration strategy at Mojave. By mapping the underground workings at DAM, we have essentially 'unlocked' the geometry of the system." – Kerrie Matthews, Managing Director & CEO
The presence of such extensive alteration signatures suggests that antimony mineralisation within the Mojave Project may be hosted across multiple structural corridors rather than isolated vein occurrences. In addition, this potentially multiplies the resource potential across the tenement package.

Structural Breakthroughs Enhance DAM's Hidden Potential
Locksley's first detailed structural mapping of the historic underground workings at DAM has revealed critical insights that will directly enhance drilling effectiveness and resource definition. The mapping identified a series of younger East-West striking shears that crosscut and displace the primary North-South mineralised veins.
| Structural Discovery | Implication | Targeting Benefit |
|---|---|---|
| East-West fault displacement | High-grade zones offset, not terminated | Enables systematic targeting of faulted extensions |
| Dip-slip and dextral movement | Precise displacement vectors identified | Improves drill hole placement accuracy |
| Multiple vein orientations | Complex but predictable geometry | Supports rapid resource growth potential |
This structural understanding explains why high-grade zones appeared to terminate abruptly in certain underground areas. However, they were actually displaced by later faulting events. By determining the exact displacement patterns, Locksley can now systematically target the faulted extensions of proven high-grade lodes.
Expanding the Mineralised Footprint
The geological campaign has successfully extended the known mineralised trends beyond the immediate DAM area. For instance, mapping south of the Hendricks prospect has revealed:
• Previously unrecognised shear zones with the same geological fingerprint as DAM
• Quartz-calcite-barite vein systems parallel to primary mineralised trends
• Intense goethite alteration indicating weathered primary sulphide mineralisation
• Quartz-dominated shear-breccia veins typical of hydrothermal mineralisation events
These discoveries suggest the mineral system in the Northern Block extends well beyond current resource estimates. Furthermore, multiple structural pathways are capable of localising high-grade antimony mineralisation.
Understanding Critical Minerals: Antimony's Strategic Importance
What is Antimony?
Antimony is a critical metalloid essential for modern defence and technology applications. It's primarily used in flame retardants, battery technology, and military applications including ammunition and night-vision equipment. The metal exhibits unique properties that make it irreplaceable in certain strategic applications.
Why It Matters to Investors
The United States currently imports 95% of its antimony requirements, primarily from China, creating significant supply chain vulnerabilities for critical defence and technology sectors. This import dependence has driven antimony onto the U.S. Critical Minerals List. Consequently, domestic production receives strong government support through initiatives like the Defense Production Act.
Locksley's mine-to-market strategy positions the company to capitalise on this strategic imperative. The Mojave Project represents one of the few advanced antimony projects in North America capable of contributing to domestic supply chain resilience.
Strategic Next Steps and Immediate Catalysts
Locksley's technical breakthroughs have established a clear pathway for systematic resource expansion and value creation. The Locksley Resources Mojave Project discovery provides multiple opportunities for immediate development.
Immediate Priorities
- Optimised drill planning incorporating newly mapped fault systems and structural controls
- Assay results from surface and underground sampling across multiple targets
- Systematic sampling along the 10-15m wide Beefeater Shear corridor
- Diamond drilling evaluation for high-precision structural targeting
Medium-term Catalysts
• Maiden drilling program at DAM with enhanced structural targeting
• Resource definition across multiple structural corridors
• Beefeater Shear drill testing following surface confirmation
• Integration with broader critical minerals strategy including rare earth elements
The company's systematic approach to structural understanding before drilling represents best-practice exploration methodology. In addition, geological insights directly translate to improved drilling success rates and resource confidence.
Investment Thesis: Multiple Pathways to Value Creation
Locksley's latest geological breakthroughs significantly strengthen the investment case across several key dimensions. The Locksley Resources Mojave Project discovery demonstrates the company's ability to unlock value through systematic exploration.
Resource Expansion Potential
The identification of multiple mineralised corridors, combined with improved understanding of structural controls, supports potential for significant resource growth beyond current DAM estimates.
Exploration Efficiency
Detailed structural mapping reduces exploration risk and improves drilling success rates. Furthermore, clear targeting criteria are now established across the project area.
Strategic Positioning
The company's focus on critical minerals aligns with U.S. strategic priorities. Antimony represents a compelling supply chain opportunity in a market dominated by single-source supply.
Technical De-risking
Underground mapping has validated the geological model and provided crucial insights for resource development. Consequently, this reduces technical uncertainty as the project advances.
