Locksley Resources Ltd Rare Earth Discovery Transforms Mojave Project Potential

Locksley Resources Uncovers Game-Changing Rare Earth Targets Adjacent to America's Only REE Mine

The Locksley Resources Ltd rare earth discovery represents a significant breakthrough in North American critical minerals exploration. Locksley Resources Limited (ASX: LKY) has delivered a breakthrough at its Mojave Project in California, with high-resolution geophysical surveys identifying two significant Thorium anomalies that could represent new rare earth element (REE) prospects directly adjacent to the Mountain Pass Mine – America's only operating REE facility.

The precision helicopter-borne survey, flown at just 35 metres altitude with 40-metre line spacing, has revealed geological signatures remarkably similar to those found at the Mountain Pass deposit. Furthermore, this positions Locksley's claims as potentially hosting parallel REE systems in one of North America's most prospective rare earth districts.

Breakthrough Geophysical Results Define New Exploration Frontiers

The comprehensive magnetic and radiometric survey has identified two distinct Thorium anomalies within Locksley's tenure that enhance the significance of the Locksley Resources Ltd rare earth discovery:

• Northern Anomaly: A pronounced Thorium signature in the northeast section of the North Block claims, coinciding with weathering features and regional drainage patterns
• Eastern Anomaly: A parallel trend located 700 metres east of the El Campo Prospect, suggesting potential for multiple mineralised corridors

These discoveries are particularly significant given their proximity to Mountain Pass. In addition, the deposit is characterised by strong Thorium signatures associated with its world-class REE mineralisation.

CEO Kerrie Matthews commented:
"The results from this high-resolution geophysical survey are a game-changer for our targeting at Mojave. Moving from broad legacy geophysical data to this level of detail is like turning on the lights in a dark room. We can now see clearly defined structural corridors and Thorium anomalies that look geologically similar to the systems known in the district."

Technical Breakthrough: From Regional to Precision Targeting

The survey represents a significant upgrade from historical regional datasets, delivering:

• High-resolution magnetics revealing complex faulting patterns and distinct magnetic domains
• Detailed structural framework to guide future target generation
• Radiometric precision capable of detecting shallow surface expressions of potential REE systems
• 1,589 line kilometres of comprehensive geophysical data

Consequently, this technical advancement provides Locksley with unprecedented clarity regarding subsurface geological structures and potential mineralisation corridors.

Understanding Thorium Signatures: A Key Indicator for REE Discovery

What is Thorium in REE exploration?

Thorium is a naturally occurring radioactive element that frequently associates with rare earth elements in geological systems. When detected through radiometric surveys, elevated Thorium levels can indicate:

• Alteration zones related to REE-bearing fluids
• Surface expressions of deeper mineralised systems
• Geological processes similar to those that concentrate rare earth elements

Why it matters for investors:

Thorium anomalies provide exploration teams with cost-effective targeting tools before committing to expensive drilling programs. However, the correlation between Thorium signatures and REE mineralisation at Mountain Pass validates this approach for the broader district.

Radiometric sensors detect gamma rays emitted from radioactive isotopes within the upper 20-30 centimetres of Earth's surface. These shallow signals can represent surface expressions of alteration zones or weathered outcrops spatially related to REE mineralisation. For instance, even small surface anomalies warrant investigation as they may indicate larger buried targets.

Strategic Location Amplifies Discovery Potential

Locksley's Mojave Project benefits from an exceptional geological address that strengthens the Locksley Resources Ltd rare earth discovery potential:

The project's position within the historic Clark Mining District, combined with its direct adjacency to MP Materials' claims, reinforces the geological continuity. Furthermore, this positioning demonstrates exploration potential across the broader rare earth system.

Immediate Field Validation and 2026 Drilling Pipeline

Locksley has mobilised field teams for immediate ground-truthing of the newly identified anomalies through:

• Geological mapping to validate geophysical interpretations
• Rock chip sampling across priority Thorium anomalies
• Structural analysis to define drill target corridors
• Preparation of 2026 drill programmes for systematic testing

The company's systematic approach ensures that geophysical targets are properly validated before advancing to drill testing. Consequently, this methodology minimises exploration risk whilst maximising discovery potential for the Locksley Resources Ltd rare earth discovery programme.

Investment Thesis: Positioning for America's Critical Minerals Future

Multiple value drivers converge at Mojave:

Rare Earth Element Upside

• Proven district geology with demonstrated REE potential
• Multiple target corridors providing exploration diversity
• Proximity to processing infrastructure reducing development risks

Antimony Strategic Value

• Historic Desert Antimony Mine representing high-grade domestic antimony potential
• Zero current U.S. production despite critical defence and technology applications
• Geopolitical supply chain diversification driving strategic value

Operational Excellence

• Systematic exploration approach from geophysics through drilling
• Proven management team with district experience
• Strategic partnerships with U.S. research institutions

Why Investors Should Follow Locksley Resources

The convergence of high-quality geophysical results, strategic location advantages, and America's critical minerals imperative positions Locksley Resources as a compelling opportunity. In addition, the company's presence in both rare earth and antimony sectors creates multiple value pathways.

Key tracking points for investors:

• Field validation results from current ground-truthing programmes
• 2026 drill programme outcomes at priority Thorium anomalies
• Strategic partnership developments in processing and downstream applications
• U.S. policy developments supporting domestic critical minerals production

The identification of multiple Thorium anomalies adjacent to Mountain Pass, combined with the company's systematic exploration approach and strategic antimony assets, creates a unique value proposition. However, success will ultimately depend on systematic validation of these geophysical targets through comprehensive field programmes and eventual drilling.

Key Takeaway:
The Locksley Resources Ltd rare earth discovery represents a strategic positioning in America's critical minerals future, with high-priority REE targets adjacent to the nation's only operating rare earth mine. With systematic exploration programmes underway and 2026 drilling planned, investors should monitor developments closely as the company advances multiple value-creating opportunities across its diversified critical minerals portfolio.
