Strategic Significance

The membership highlights the Company’s growing presence in the U.S. critical minerals landscape. The CMI is dedicated to developing technology solutions that reduce reliance on foreign supply chains for materials essential to electric vehicles, renewable energy, and national security.

Locksley's flagship Mojave Project in California hosts a potential resource base, rich in antimony and rare earth elements (REEs). As U.S. priorities shift toward domestic sourcing and downstream processing innovation, Locksley is well positioned to supply valuable feedstock and practical, field scale expertise to joint R&D initiatives under the CMI umbrella.

CMI Collaboration and Forward Plan

The initial focus within the CMI includes advancing rare earth separation technologies and exploring novel alternative antimony oxide applications. The Company will contribute mineralised samples to inform broader DOE aligned research efforts and aligns with the work Locksley is undertaking with Colombia and Rice University.

Through the CMI partnership, the Company will:

• Access cutting edge research and innovative technologies for the processing, separation, and purification of rare earth elements and other critical minerals

• Benefit from advancements in extraction techniques applied to ores, industrial waste, and recycled materials

• Collaborate with premier U.S. national laboratories, including Oak Ridge and Lawrence Livermore national laboratories, to leverage their cutting-edge research, specialised infrastructure, and government-supported innovation programs, all aimed at building secure, resilient domestic supply chains for critical minerals

• Strengthen its role as a vertically integrated supplier aligned with U.S. clean energy and supply chain security objectives.

Participation in CMI aligns with broader U.S. initiatives that promotes resource security and technological innovation, including the Department of Energy’s ARPA-E program, the DOE Loan Programs Office, and the Department of Defence supported initiatives such as TechConnect ecosystem.

The Board views this development as a key strategic advancement, significantly strengthening Locksley’s U.S. footprint and accelerating its downstream innovation and development roadmap.
