Locksley Resources Limited Advances Antimony Supply Strategy

Perth, Australia (ABN Newswire) - Locksley Resources Ltd (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) is pleased to advise it has moved to secure additional beneficiated ore supply to complement development of its Desert Antimony Mine at Mojave, California. This initiative forms part of the Company's broader mine to market strategy targeting supply for the U.S. defense and energy markets, while also strengthening the commercial pathway for its DeepSolv(TM) processing technology being developed with Rice University.

Highlights

- Locksley seeks to strengthen the commercial pathways for DeepSolv(TM) processing method, by entered into a Non-Binding Heads of Agreement with EV Resources Limited (EVR) to purchase EVR's Antimony material via an Ore Sales Agreement

- Availability of 3rd party material is a key element for the development of DeepSolv(TM) and access to the USD $1bn+ domestic US Antimony market

- Expands and diversifies ore feedstock available for the processing development and downstream validation being conducted by Rice University on the DeepSolv(TM) product

- Enables Locksley to integrate both domestic ore from Mojave and additional North American supply into U.S. refining, accelerating the availability of critical materials

- Access to multiple ore supplies is complementary to the development of the Desert Antimony Mine at Mojave and advances Locksley's strategy of providing domestic security of USA antimony supply necessary for defence security

- Will provide priority access to antimony samples from EV Resources' Los Lirios operations for Rice University DeepSolv(TM) testwork, promoting a diversified and resilient North American supply chain

- Contingent on Locksley and EVR successfully negotiating a binding Antimony Ore Sales Agreement and subject to EVR shareholder approval, Locksley will make a strategic investment of A$0.75 million in EV Resources Limited (ASX:EVR)

Strategic Rationale: DeepSolv(TM) Processing Pathway

The securing of EVR beneficiated ore will underpin Locksley's ability to accelerate deployment of DeepSolv(TM), a proprietary solvometallurgical process developed with Rice University, by ensuring additional steady and diverse feedstock supply. This strengthens the Company's position to:

- Provide immediate beneficiated ore supply to complement Mojave ore and bridge U.S. requirements until domestic mining commences

- Validate the DeepSolv(TM) process across multiple ore types, ensuring resilience and efficiency in downstream refining

- Secure 3rd party material as a key element for establishing the scale of DeepSolv(TM) and access to the USD $1bn+ domestic US Antimony market

- Advance production of defense-grade and energy-grade antimony products for U.S. applications

- Demonstrate to U.S. Government stakeholders the practical delivery of non-Chinese feedstock through advanced U.S.-based processing

- Position Locksley as a leading partner in reshaping North American supply chains for critical minerals

Strategic Locksley Investment and Ore Sales Agreement

LKY and EVR have entered into a non-binding Heads of Agreement. Contingent upon LKY and EVR entering into a binding Ore Sales Agreement, and subject to EVR shareholder approval,

LKY will make a strategic investment of A$0.75 million. This agreement provides a framework for EVR to supply antimony concentrate from its Los Lirios operations to Locksley, with the following key points:

- Purpose: The Agreement sets out the non-binding commercial framework under which EVR and LKY will cooperate to establish a strategic relationship for material testwork and develop production and value creation.

- Testing and Validation: EVR will send representative samples of ore to Locksley's refining facility to test and confirm ore properties and processing viability.

- Pathway to Binding Agreement: The parties will seek to enter into a binding Ore Sales Agreement which will set out the commercial framework for a long-term supply partnership, with an initial focus on offtake to support downstream processing studies.

- Mutual Strategic Benefit: The cooperation secures a potential long-term customer for EVR's concentrate while reinforcing Locksley's access to a secure supply of antimony for its proprietary refining technology.

Pat Burke, Chairman of Locksley Resources, commented:

"This agreement potentially strengthens our mine-to-market strategy by complementing our Mojave development with additional concentrate supply from EVR. By securing nearshore feedstock alongside our fast-tracked mining plans in California, Locksley will be well positioned to accelerate the U.S. return to domestic antimony processing. With Rice University's support and the deployment of our DeepSolv(TM) technology, our pathway demonstrates that Locksley is assembling the resources, partnerships, and technology to ensure secure, scalable, and independent antimony supply for the United States."

About Locksley Resources Limited:

Locksley Resources Limited (ASX:LKY,OTC:LKYRF) (OTCMKTS:LKYRF) (FRA:X5L) is an ASX-listed explorer focused on critical minerals in the United States of America. The Company is actively advancing exploration across the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley Resources aims to generate shareholder value through strategic exploration, discovery and development of critical minerals for U.S.

Locksley Resources Limited CEO and COO Appointed to Fast Track US Mine to Market Strategy

Perth, Australia (ABN Newswire) - Locksley Resources Ltd (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) is pleased to announce the appointment of Ms. Kerrie Matthews as Chief Executive Officer (CEO) and Mr. Danny George as Chief Operating Officer (COO). These appointments significantly strengthen the Company's executive leadership team at a pivotal time as Locksley advances the Desert Antimony Mine ("DAM"), accelerates downstream processing and the mine-to-market solutions for antimony in the United States.

Ms. Kerrie Matthews - Chief Executive Officer

Ms. Matthews is a highly accomplished executive leader with over two decades of experience delivering nationally significant and capital-intensive projects in the resources and infrastructure sectors.

For Locksley, this capability ensures that DAM is advanced efficiently while building the framework for U.S. downstream processing an area where there are currently no large-scale commercial solutions in operation.

Mr. Danny George - Chief Operating Officer

Mr George is a seasoned senior executive with extensive global experience in feasibility studies and the execution of EPCM and EPC contracts across the mining and energy sectors. He has successfully delivered major projects with WSP, Fortescue, Mineral Resources, Thyssenkrupp and Ausenco, working with leading companies such as Vale, BHP and Hancock Prospecting. His track record includes copper and lithium concentrators, iron ore and coal export facilities, as well as emerging technology projects in hydrogen and green iron.

Danny's technical breadth and expertise in rapid project delivery, capital efficiency and large-scale project execution will provide Locksley with the operational discipline and agility required to advance the DAM Project into production at speed. His proven leadership in delivering high-value projects across multiple geographies equips the Company with the capability to manage both upstream ore development and downstream plant construction within an accelerated timeframe.

Strategic Importance

The appointments of Ms. Matthews and Mr. George provide Locksley with the executive leadership, experience, and technical expertise required to deliver a mine-to-market antimony solution in the United States. Importantly, both have proven ability to move quickly from study to execution, ensuring Locksley is positioned as a fast mover capable of delivering critical U.S. supply ahead of the curve. Their combined backgrounds in critical minerals, major project delivery, and contract mining directly address one of the most pressing U.S. supply chain constraints: the absence of large-scale commercial antimony processing capacity.

Following the Company's excellent metallurgical results at the Desert Antimony Mine, Locksley is now positioned to translate technical validation into commercial execution. In parallel with conventional mine development at DAM, the Company is actively assessing non-traditional mining and extraction methods to bring forward initial supply. This includes evaluating flexible and modular mining solutions, contract mining approaches, and low capital processing pathways that can be rapidly deployed to align with the immediate demand from the U.S. Government for secure antimony supply.

By advancing DAM with both traditional and innovative development methods, and by establishing downstream processing capacity, Locksley is uniquely placed to play a pivotal role in strengthening U.S. and allied supply chains. This strategy underpins Locksley's pathway to 100% Made in America Antimony and positions the Company to attract government and institutional support as part of broader initiatives to secure the supply of critical minerals essential for defense, energy transition, and advanced technology applications.

Resignation of Director

Technical Director, Julian Woodcock, has resigned to focus on his Managing Director role at Viking Mines Ltd. Mr Woodcock has played a key role in the accelerated progress of the Company's Mojave Project and will continue to provide strategic guidance as a technical consultant.

Pat Burke, Chairman Locksley Resources, commented:

"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.

This positions Locksley to deliver value for shareholders while directly addressing one of the United States' most critical national security and energy transition priorities. I would like also sincerely to thank Julian for his services to Locksley during its critical formative period."

Next Steps

Locksley is progressing multiple parallel workstreams to accelerate the development of the Desert Antimony Mine ("DAM") and advance downstream processing:
