Brings Company’s Total Claims to 491 in Area Housing the Only Rare Earths Producing Mine in U.S.
Move Expands Locksley’s Exploration Pipeline Across Antimony, Rare Earths Elements and Polymetallic Prospects
SAN BERNARDINO, Calif., Sept. 11, 2025 /PRNewswire/ — Locksley Resources Limited (ASX: LKY; OTCQB: LKYRF), announced it has significantly expanded its strategic footprint within the Mojave Critical Minerals Corridor in California through the staking of an additional 249 claims. This brings the company’s total landholding to 491 claims.
The new claims are adjacent to Locksley’s existing tenement position and adjoin MP Materials landholding, which includes the Mountain Pass Rare Earth Mine. The new claims also secure additional acreage for Locksley in that they abut the recently identified antimony, rare earths elements (REEs) and polymetallic mineralization reported by the company.
"These additional claims significantly strengthen Locksley’s competitive positioning within one of the most prospective critical minerals regions in the U.S.," said Nathan Lude, Head of Strategy, Capital Markets and Commercialization for the company. "With demand for antimony and REEs underpinned by U.S. supply chain security initiatives, the expanded landholding provides Locksley with a broader platform to advance multiple exploration and development opportunities," he noted.
The south-east claims encompass the favorable gneissic geology, which hosts the Mountain Pass mine and carbonatites. "Significantly there are substantial regional north to north-west striking structures evident in the magnetic geophysics datasets," said Julian Woodcock, Locksley’s technical director. "These transgress across the areas staked, which conceptually have the potential to host pathways for REE bearing carbonatites and be related to other styles of mineralization," he said.
Woodcock added that the Northern claims are 3km directly along strike from Dateline Resources Colosseum Gold Project. "In addition, the USGS geochemical database indicates polymetallic and precious metals occurrences in the area immediately adjoining the new northern claims. As such there are multiple commodity opportunities evident within this claim area."
Lude added, "Importantly, several of the new claims directly adjoin the Mountain Pass larger claim package, underlining the strategic significance of Locksley’s footprint within the corridor. This positioning enhances potential for both exploration discovery and long-term commercialization pathways, including downstream processing partnerships in line with U.S. government priorities for supply chain resilience."

Locksley Resources is an Australian-based explorer focused on critical minerals and base metals, with assets in both the U.S. and Australia. The company is actively advancing its U.S. asset, the Mojave Project, in California, targeting rare earth elements (REEs) and antimony. The company has also announced a strategic collaboration with Rice University to develop DeepSolv™, for domestic processing of North American antimony. The agreement is the first step in the initiation of Locksley’s U.S. Critical Minerals and Energy Resilience Strategy to accelerate "mine-to-market" deployment of antimony in the U.S.
