Locksley Resources Leadership Changes Accelerate US Antimony Production

Locksley Resources Bolsters Leadership to Fast-Track US Antimony Production

Locksley Resources Limited (ASX: LKY, OTCQB: LKYRF, FSE: X5L) has appointed two seasoned industry executives to its leadership team, positioning the company to accelerate its U.S. mine-to-market antimony strategy. This strategic enhancement of executive capability comes as Locksley focuses on addressing one of America’s most critical national security and supply chain vulnerabilities.

Elite Leadership Team Assembled to Drive Rapid Antimony Production

Locksley Resources has significantly strengthened its executive capability with the appointments of Kerrie Matthews as Chief Executive Officer and Danny George as Chief Operating Officer. These strategic hires bring decades of combined experience in critical minerals development and major project execution at a pivotal moment when the company is advancing its Desert Antimony Mine (DAM) in California.

The appointments represent a substantial upgrade to Locksley’s project execution capabilities:

• • Kerrie Matthews brings over 20 years of executive leadership in delivering capital-intensive projects, including BHP’s $3.8 billion South Flank Project and Iluka’s $1.8 billion Eneabba Rare Earths Refinery. Her expertise in fast-tracking regulatory approvals and stakeholder alignment will be crucial for Locksley’s accelerated U.S. strategy.

• • Danny George contributes extensive global experience in feasibility studies and executing large-scale mining projects for industry giants including Vale and BHP. His track record in rapidly bringing projects online with capital discipline positions Locksley to move quickly in the U.S. market.

“The appointments of Kerrie and Danny significantly enhance our executive capability at a pivotal moment for Locksley. Their leadership supports our strategy to transform the historic Desert Antimony Mine into a modern, fully integrated mine-to-market supply chain for 100% Made in America Antimony,” said Pat Burke, Chairman of Locksley Resources.

Understanding Antimony: America’s Critical Mineral Vulnerability

Antimony represents one of the United States’ most significant critical mineral vulnerabilities. This strategic metal is essential for multiple applications:

• • Defense Applications: Used in ammunition, flame retardants for military vehicles, and infrared detection systems

• • Energy Transition: Critical component in solar panels, wind turbines, and grid-scale battery storage

• • Industrial Uses: Vital for semiconductor manufacturing, metal alloys, and flame retardants

Despite its importance, the United States currently has no domestic antimony production, creating a severe supply chain vulnerability. China dominates global antimony supply, controlling over 60% of production and 80% of refined antimony output.

What Makes Antimony So Critical?

Antimony is a metalloid element that has become increasingly important in modern technological applications. Its unique properties make it valuable across multiple industries:

1. Military and Defense: Antimony is crucial for hardening lead in ammunition and creating flame-retardant materials used in military vehicles, aircraft, and uniforms.
2. Energy Storage: In grid-scale battery storage systems, antimony compounds enhance performance and stability, making them essential for renewable energy integration.
3. Electronics: Semiconductor manufacturers rely on antimony for creating precise electrical properties in various components.
4. Fire Safety: Antimony trioxide serves as a synergist in flame retardants, improving their effectiveness in consumer products, building materials, and transportation equipment.

The U.S. Department of Defense has classified antimony as a critical material, listing it among the minerals most essential for national security and most vulnerable to supply disruption. This designation underscores the strategic importance of developing domestic antimony resources.

Locksley’s Desert Antimony Mine in California represents one of the highest-grade known antimony occurrences in the U.S., positioning the company to address this critical supply gap.

Accelerated Development Strategy Underway

Following recent metallurgical testing that achieved 85.9% recovery rates at the Desert Antimony Mine, Locksley is pursuing multiple parallel workstreams to fast-track production:

• • Financing and permitting applications are underway to support near-term mine development

• • Strategic partnerships with government and industry stakeholders are being formed to align with U.S. national security priorities

• • Technology pathways are progressing through Rice University’s DeepSolv™ program and external ore supply agreements

• • Non-traditional mining methods are being evaluated to accelerate early supply to meet immediate U.S. government demand

The company is pursuing both conventional mine development and innovative extraction approaches to bring forward initial supply, including flexible modular mining solutions and low-capital processing pathways.

Technical Validation Drives Confidence

The recent metallurgical results from the Desert Antimony Mine represent a significant technical milestone for Locksley. The 85.9% recovery rate validates the commercial potential of the resource and provides a solid foundation for advancing both mining and processing operations.

These results enable Locksley to:

1. Optimise Processing Design: Develop efficient processing circuits tailored to the specific mineralogy of the Desert Antimony Mine
2. Reduce Technical Risk: Demonstrate to potential partners and investors that the resource can be economically processed
3. Accelerate Development Timelines: Move forward with confidence in both conventional and innovative extraction methods

With these technical parameters established, the company’s strengthened leadership team is well-positioned to execute the accelerated development strategy.

Investment Thesis: Addressing a National Security Priority

Locksley Resources presents a compelling investment opportunity based on several key factors:

1. Strategic Asset: The Desert Antimony Mine represents a rare domestic source of a critical mineral deemed essential by the U.S. government
2. Experienced Leadership: The new executive team brings proven capability in delivering billion-dollar mining projects
3. Technical Validation: Recent metallurgical testing has confirmed the project’s commercial viability
4. Government Priority: Antimony has been identified as a critical vulnerability in U.S. supply chains, creating potential for government support and funding
5. First-Mover Advantage: As one of the few companies advancing antimony production in the U.S., Locksley has positioned itself at the forefront of addressing this supply gap

The company’s dual focus on both upstream mining and downstream processing differentiates it from peers and aligns perfectly with the U.S. government’s push for secure domestic supply chains.
