Locksley Resources Rare Earth Expansion Doubles Mojave Critical Minerals Footprint

Mojave Critical Minerals Hub Expansion Creates Multi-Commodity Opportunity

Locksley Resources (ASX: LKY) has made a significant strategic move by more than doubling its landholding in California’s critical minerals-rich Mojave region. The company has staked an additional 249 claims, expanding its total footprint to over 40 square kilometres of highly prospective ground directly adjacent to MP Materials’ Mountain Pass Mine – the only producing rare earth mine and processing facility in North America.

The expansion increases Locksley’s total claims to 491 and positions the company as a key player in a region that’s becoming increasingly strategic for U.S. mineral security. The new claims not only abut Locksley’s existing tenure but also secure ground just 3km north and along strike of Dateline Resources’ (ASX: DTR) Colosseum Mine, with identified polymetallic and precious metals potential.

“This expansion materially enhances our strategic footprint in the Mojave Corridor, a region central to U.S. critical minerals security. With additional ground abutting our existing claims and adjoining the MP Materials Mountain Pass larger claim package, we are exceptionally well positioned to advance a diversified pipeline of exploration and downstream opportunities across antimony, rare earths, other critical minerals and precious metals potential.” – Julian Woodcock, Locksley’s Technical Director

Strategic Positioning in America’s Critical Minerals Corridor

The expansion significantly enhances Locksley’s competitive positioning within one of the most sought-after critical minerals regions in the United States. The strategic value of this move is multi-faceted:

• • Direct adjacency to North America’s only rare earth producer – The new claims border MP Materials’ Mountain Pass operation

• • Favourable geology – The southeast claims encompass the same gneissic geology that hosts the Mountain Pass mine and carbonatites

• • Structural advantages – Regional north to north-west striking structures evident in magnetic geophysics datasets represent potential pathways for REE-bearing carbonatites

• • Diversified commodity exposure – Beyond rare earths, the expanded footprint includes antimony prospects and polymetallic potential

The timing of this expansion aligns perfectly with growing U.S. government initiatives to secure domestic supply chains for critical minerals, particularly those heavily dominated by Chinese production such as rare earths and antimony.

Understanding the Geological Opportunity

The newly staked ground presents multiple exploration targets based on favourable geological indicators:

Southeast Claims Package

These claims encompass the favourable gneissic geology hosting the Mountain Pass mine and carbonatites. Regional north to north-west striking structures visible in magnetic geophysics data potentially provide pathways for REE-bearing carbonatites and related mineralisation styles.

Northern Claims Package

Located just 3km directly along strike from Dateline Resources’ Colosseum Gold Project, this area shows significant promise. The USGS geochemical database indicates polymetallic and precious metals occurrences in immediately adjacent areas, suggesting multiple commodity opportunities.

What Are Carbonatites and Why Do They Matter?

Carbonatites are rare igneous rocks composed of more than 50% carbonate minerals. These unusual formations are extremely important to investors interested in rare earth elements for several reasons:

• • Carbonatites host some of the world’s richest rare earth deposits, including Mountain Pass

• • They typically contain higher concentrations of rare earths than other deposit types

• • The mineralogy of carbonatites often allows for simpler processing compared to other REE sources

• • Only about 500 carbonatite occurrences are known worldwide, making them extremely valuable when discovered

For investors, a company with exploration rights over potential carbonatite structures adjacent to a proven deposit represents a significant opportunity, especially given the critical shortage of domestic rare earth production in the United States.

Near-Term Development Roadmap

Locksley has outlined a clear path forward following this strategic expansion:

1. Immediate focus: Complete registration activities of the new claims with required Federal and State Agencies
2. Data integration: Compile and integrate geological data from the expanded tenure
3. Field programs: Design stream sediment and rock chip sampling programs across the area, scheduled for Q4 2025
4. Target development: Systematically explore high-priority antimony, REE and polymetallic anomalies
5. Regulatory advancement: Progress permitting activities across the consolidated claim block to expedite drilling approvals

This systematic approach demonstrates management’s commitment to rapidly advancing exploration while maintaining regulatory compliance in a jurisdiction known for its complex permitting environment.

The U.S. Critical Minerals Advantage

Locksley’s expanded Mojave footprint aligns perfectly with the company’s “Mine-to-Market” strategy, which encompasses both upstream project development and downstream critical minerals processing. This integrated approach is particularly valuable in the current geopolitical context:

The U.S. government has designated both rare earths and antimony as “critical minerals” essential to economic and national security, implementing various funding and policy initiatives to encourage domestic production.

Why Investors Should Follow Locksley Resources

Locksley Resources represents a compelling opportunity for investors interested in the critical minerals sector for several key reasons:

1. Strategic Location: The expanded footprint in the Mojave Critical Minerals Hub positions Locksley adjacent to North America’s only producing rare earths mine
2. Multi-Commodity Exposure: The portfolio provides diversified exposure to rare earths, antimony, and polymetallic potential
3. U.S. Government Alignment: Locksley’s focus aligns perfectly with U.S. initiatives to secure domestic supply chains for critical minerals
4. Experienced Management: The team has demonstrated strategic vision in consolidating this significant land position
5. Near-Term Catalysts: With field programs planned for Q4 2025, investors can expect regular news flow

In a market where critical minerals projects with U.S. exposure are increasingly valued at a premium, Locksley’s expanded Mojave footprint places the company in an enviable position to capitalise on growing demand for secure, domestic sources of rare earths and antimony.

As U.S. policy continues to prioritise domestic critical minerals production and processing capacity, companies like Locksley with strategic land positions adjacent to existing infrastructure are uniquely positioned to benefit from both exploration success and potential partnership opportunities with downstream processors seeking secure supply.
