Locksley Resources (ASX:LKY | OTCQX:LKYRF | FSE:X5L) strengthens leadership for U.S. antimony commercialisation

In a decisive move underscoring its transformation from explorer to emerging producer, Locksley Resources Limited (ASX:LKY | OTCQX:LKYRF | FSE:X5L) has appointed Kerrie Matthews as Managing Director and Chief Executive Officer.

The appointment marks the next stage in the company’s U.S. mine-to-metal strategy for antimony, a critical mineral central to America’s defence and clean energy supply chains.

Highlights

• Kerrie Matthews appointed Managing Director and CEO
• Successfully produced the first wholly American-made antimony ingot in decades
• Progressing pilot-scale development and government funding initiatives in the U.S.
• Advancing offtake readiness with strategic partners including Hazen Research, GreenMet and Rice University
• Board restructuring follows the resignation of Director Steve Woodham

Under Ms Matthews’ leadership, Locksley has already achieved a milestone unmatched in decades: the production of a 100 per cent American-made antimony ingot. This achievement validates the company’s ability to establish a fully domestic supply chain for one of the most strategically significant critical minerals.

Chairman Patrick Burke described her elevation as both a natural progression and a reflection of the Board’s confidence in her leadership.

“Since joining the Company as Chief Executive Officer, Ms Matthews has delivered tangible milestones that de-risk our U.S. strategy and set Locksley up for commercial engagement. Elevating her to Managing Director aligns our leadership structure with the clear near-term priorities of pilot-scale development, securing government programs, and achieving offtake readiness,”  he said.

The appointment also coincides with a period of mounting geopolitical urgency surrounding critical minerals.

With the United States currently devoid of domestic antimony production, Locksley Resources Mojave Project in California stands out as one of the few viable sources capable of contributing to the nation’s resource independence.

The project encompasses more than 490 claims across the Mojave Desert, adjoining tenements held by MP Materials at the Mountain Pass rare earths complex, and hosts the historic Desert Antimony Mine, last operated in 1937.

Locksley’s integrated approach blends resource development with advanced processing and separation technologies through partnerships with leading American research and industrial groups.

This collaboration supports the company’s goal of establishing a vertically integrated supply chain that feeds directly into U.S. defence, semiconductor, and clean technology markets.

Kerrie Matthews noted that the company’s position within this evolving landscape presents both opportunity and responsibility.

“The U.S. antimony market is undergoing a fundamental reset, with government funding, defence stockpiling and private sector demand all converging to rebuild a secure, domestic supply chain. Our progress at the Mojave Project, together with trusted U.S. partners like Hazen Research, GreenMet and Rice University, puts Locksley at the centre of that transformation,” she said.

Locksley’s collaboration with GreenMet, a Washington-based advisory firm specialising in critical minerals policy, continues to shape its pathway through U.S. permitting and funding frameworks.

This alignment with national priorities positions the company to benefit from renewed federal focus on supply chain resilience, particularly for materials deemed essential to energy and defence systems.

As Locksley advances toward pilot-scale production, its strategic trajectory reflects the shifting dynamics of global critical minerals supply.

With leadership now firmly anchored in the U.S. commercialisation phase, the company’s focus is set on operational execution, securing government partnerships, and establishing long-term offtake agreements that could underpin the next chapter of domestic antimony supply.

In a market increasingly defined by geopolitical competition and resource nationalism, Locksley’s ascent from exploration to production readiness marks a rare example of alignment between corporate capability and national interest, one that investors will likely watch closely as the U.S. critical minerals framework continues to take shape.
