Mojave Project Soars: 400% Increase in Antimony Target Strike Length
Locksley Resources (ASX: LKY) has achieved a major breakthrough at its Mojave Project in California, with recent structural mapping dramatically expanding the target mineralised corridor at the Desert Antimony Mine (DAM) Prospect from 300 meters to 1.2 kilometers—a remarkable 400% increase in potential scale.
Strategic Critical Minerals Hub Emerging in California
The expanded structural mapping has not only extended the primary target zone but also identified a parallel structural target 150 meters west of the main DAM structure, pointing to a multi-zone system with district-scale potential. This development significantly enhances the project's prospects as a strategic U.S. critical minerals hub, perfectly aligned with accelerating domestic supply chain initiatives.
"Our second structural mapping program at the Mojave Project has markedly advanced our geological understanding and confirmed the substantial exploration potential of this critical district," said Locksley Resources CEO Kerrie Matthews. "The fourfold expansion of the Desert Antimony Mine target horizon has fundamentally changed the scale of the opportunity, demonstrating the potential for a much larger mineralised system."
Key Structural Discoveries Transform Project Potential
The comprehensive mapping program, conducted by specialist structural geologists, has delivered five critical outcomes:
- Extended the target horizon to 1.2 km of strike length, dramatically increasing scale potential
- Identified a parallel structural zone 150m west of the main mineralised trend
- Discovered multiple lamprophyre dykes indicating deep-seated mantle-tapping structures
- Created updated 3D geological models enhancing structural understanding
- Defined 18 priority target areas for follow-up detailed mapping and sampling
The updated geological interpretation highlights steep north-plunging intersections between mapped shear zones and folded host rocks as potential mineralisation controls. These findings have been incorporated into a new 3D geological model that identifies seven priority surface sampling targets to guide the next phase of exploration.
High-Grade Silver Discovery Expands Polymetallic Potential
Adding to the project's prospects, initial grab sampling at the Hendricks Prospect returned high-grade silver assays of 216 g/t Ag with anomalous lead (0.3% Pb), zinc (0.9% Zn), and copper (0.1% Cu), indicating a broader polymetallic system. The company also identified previously unknown historical workings at the Hendricks Prospect.
Understanding Antimony: A Critical U.S. Strategic Material
Antimony is classified as a critical mineral by the U.S. government due to its essential applications in defense systems, semiconductors, flame retardants, and lead-acid batteries. Despite high demand, the United States currently has no domestic antimony production, making Locksley's Mojave Project strategically important for national security.
The mineral is typically found in narrow, high-grade vein deposits, with stibnite (Sb₂S₃) being the primary ore mineral. Antimony deposits commonly form in low to moderate temperature hydrothermal systems along structural pathways—precisely the geological setting being mapped at Locksley's Desert Antimony Mine Prospect.
Strategic Alignment with U.S. Critical Minerals Policy
The scale and geometry of the target zones identified at Mojave align with the type of high-grade, clean stibnite feedstock required to fast-track U.S. antimony supply chains under programs such as Defense Production Act (DPA) Title III and Department of Energy ARPA-E initiatives.
This timing is advantageous, as the U.S. continues to advance policies promoting domestic critical mineral production to reduce dependence on foreign sources, particularly from China, which dominates global antimony production.
Next Steps: Accelerated Exploration Program
Locksley has outlined an aggressive exploration roadmap:
- Third phase structural mapping program to commence in late November 2025
- Detailed surface sampling across the newly identified target zones
- Development of a JORC Exploration Target to guide future drilling programs
- Further investigation of REE potential at the Junipero Prospect, located just 1.1km north of the Mountain Pass Mine
