Highlights

  • Locksley shares rose 37.5% to AUD 0.495 on 12 September 2025 during trading.

  • Company staked 249 new claims, expanding total holdings to 491 across 40 sq km.

  • New ground adjoins MP Materials’ Mountain Pass Rare Earth Mine and lies near Dateline Resources’ Colosseum Mine.

Locksley Resources Ltd (ASX:LKY) saw its share price increase 37.5% to AUD 0.495 on 12 September 2025, following the announcement of a significant landholding expansion in California’s Mojave Critical Minerals Corridor.

The company confirmed that it has staked 249 new claims, effectively doubling its land position to 491 claims covering more than 40 square kilometres of ground considered prospective for antimony, rare earth elements (REEs), and polymetallic mineralisation.

Expansion Adjoining MP Materials and Colosseum Mine

The newly acquired ground is directly adjacent to Locksley’s existing tenements and borders the landholding of MP Materials, owner of the Mountain Pass Rare Earth Mine — the only producing rare earths mine and processing facility in North America.

In addition, Locksley secured a northern package of claims located three kilometres along strike from Dateline Resources’ (ASX: DTR) Colosseum Gold Project. Geological datasets from the United States Geological Survey (USGS) indicate the area contains polymetallic and precious metals occurrences, supporting the broader exploration potential.

Strategic Positioning in U.S. Critical Minerals Corridor

The expansion aligns with U.S. government priorities to secure domestic supply chains for critical minerals, particularly antimony and REEs, which are essential for defence, technology, and renewable energy industries.

The south-east claim package covers favourable gneissic geology known to host carbonatites at Mountain Pass. Magnetic geophysics datasets show regional structures that may serve as pathways for REE-bearing mineralisation.

The northern claims provide Locksley with exposure to multiple commodity opportunities, including precious metals and polymetallic systems.

Claim Staking and Next Steps

Locksley has completed the staking process and filed the required documentation. No competing claims were identified during the process. While the adjudication process is still required to finalise mineral rights, the company indicated confidence in securing confirmation.

Looking ahead, Locksley will focus on:

  • Completing registration of the new claims with federal and state agencies.

  • Integrating new geological datasets into its exploration model.

  • Designing stream sediment and rock chip sampling programs, scheduled for Q4 2025.

  • Advancing permitting activities across the consolidated claims to expedite drilling approvals.

The expansion doubles Locksley’s tenure within one of the most prospective critical minerals regions in the United States, creating an enlarged platform for systematic exploration across antimony, REEs, and polymetallic targets.
