Leadership Shift to Drive U.S. Antimony Strategy

Locksley Resources Limited has announced a significant leadership change with the appointment of Kerrie Matthews as Managing Director and CEO, effective October 29, 2025. This move reflects the board’s confidence in Matthews’ proven ability to execute the company’s ambitious U.S. mine-to-metal strategy, particularly after the successful production of the first wholly American-made antimony ingot in decades.

Matthews’ elevation aligns the company’s leadership with its near-term priorities, advancing pilot-scale production, securing non-dilutive government funding, and progressing critical offtake agreements. Her track record in delivering tangible milestones has been pivotal in de-risking Locksley’s U.S. operations and positioning the company at the forefront of domestic critical minerals supply.

Strategic Importance of the Mojave Project

Central to Locksley’s strategy is the Mojave Project in California’s Mojave Desert, which hosts the historic Desert Antimony Mine and significant rare earth element prospects. The project’s location adjacent to MP Materials’ claims underscores its geological potential and strategic value. With the U.S. currently lacking domestic antimony production, the project’s high-grade antimony deposits are critical to rebuilding a secure, sovereign supply chain for this essential metal.

Antimony’s role in defense systems, semiconductors, and metal alloys makes it a priority mineral amid rising geopolitical tensions and supply chain vulnerabilities. Locksley’s integrated mine-to-market approach, supported by partnerships with U.S. research institutions like Hazen Research and Rice University, aims to establish a fully domestic supply chain that aligns with national security and economic objectives.

Board Changes and Future Outlook

Alongside Matthews’ appointment, Steve Woodham has resigned from the board to pursue other interests. The company acknowledged Woodham’s contributions during a critical phase of development, highlighting the collaborative effort behind Locksley’s progress.

Chairman Patrick Burke praised Matthews’ leadership, emphasizing the company’s momentum toward pilot-scale production and commercial readiness. Matthews herself expressed enthusiasm about the transformative potential of the U.S. antimony market, driven by government funding, defense stockpiling, and private sector demand converging to rebuild domestic supply chains.

As Locksley advances its pilot production and seeks to secure government programs and offtake agreements, the company is poised to play a pivotal role in the U.S. critical minerals landscape.

Bottom Line?

Locksley’s leadership realignment signals a decisive push toward commercialising U.S. antimony production amid rising strategic demand.
