HIGHLIGHTS FOR THE QUARTER:

MOJAVE CRITICAL MINERALS ANTIMONY AND RARE EARTHS PROJECT

(California, USA)

Overview and Operations

During the Quarter, Locksley delivered significant advancements at its Mojave Project, strategically located just 1.4 km from the Mountain Pass REE mine, the only active rare earths producer in the U.S. The Company remains focused on near-term drill execution across both antimony and REE targets, with key regulatory, technical and operational milestones achieved at the Desert Antimony Mine (DAM) and El Campo prospects.

Key Activities Included:

DOWNSTREAM PROCESSING & TECHNOLOGY DEVELOPMENT

Locksley Resources is aggressively advancing its strategy to establish an independent, domestic supply chain for critical antimony in the United States, positioning the Company beyond just an upstream explorer. This strategy is driven by our key collaboration with Rice University in Texas, focused on the breakthrough green hydrometallurgical DeepSolvTM technology.

Rice University Partnership: Dual Thrusts of Innovation

The partnership is structured around two critical thrusts that directly align with U.S. energy and national security mandates:

Thrust 1: Green DeepSolvTM Antimony Extraction (IP Platform)

This core technology research focuses on developing a scalable, low-carbon pathway for the efficient extraction and refining of antimony (Sb) from our Mojave Project feedstock. The aim is to create a superior, environmentally responsible alternative to traditional pyrometallurgical smelting processes, which are typically high-cost and emissions-intensive. This initiative is expected to generate a jointly owned intellectual property (IP) platform which will underpin Locksley's future domestic refining capability

Thrust 2: Antimony-Based Battery Materials

This research stream investigates the application of antimony products in next-generation energy storage. Antimony is a key component in advanced battery technology including molten salt batteries, offering high performance and thermal stability essential for gridscale and defence applications. This work positions Locksley to capture downstream value as part of the emerging U.S. clean energy supply chain.

Metallurgical Success and Product Focus

The Company's recent metallurgical success demonstrated the ability to produce a superior high-grade antimony concentrate of 68.1% Sb, providing essential feedstock validation for the DeepSolv TM technology. This robust concentrate supports a scalable, low-carbon pathway to produce the final, marketable antimony products required by U.S. industry.

Corporate and Capital Markets

Subsequent Events

Subsequent to the Quarter, Locksley announced the successful casting of the first 100% American-made antimony ingot metal in decades, representing a revival of domestic antimony production capability within the United States. The ingot was produced using concentrate sourced from non-Chinese feedstock and processed entirely on U.S. soil, validating the Company's mine-to-metal supply chain strategy. This breakthrough demonstrated the technical feasibility of restoring antimony refinement in America for the first time in decades and provided a tangible foundation for future downstream processing and government engagement under the Defense Production Act and Inflation Reduction Act frameworks.

TOTTENHAM COPPER-GOLD PROJECT

(NSW, Australia)

Limited exploration activities were carried out on the Tottenham Project during the Quarter, given the increased focus and advancements at the Mojave Project. Whilst the Board continues to believe strongly in the potential of the Tottenham Project, a strategic review is underway to determine the ideal path to progress future development of this exciting copper gold project.

CORPORATE

Financial Position

Following the exploration activities, Locksley had a cash position of approximately $7.24 million at the end of the September Quarter. Related party payments for the Quarter are as outlined in the Appendix 5B at section 6.1*, a total of $321k which includes the directors' fees and statutory superannuation paid to directors. Other ASX Requirements ASX Listing Rule 5.3.1: Exploration and Evaluation expenditure during the Quarter was $875k focused on Mojave fieldwork and assays, as well as metallurgical testwork for downstream processing.


About Locksley Resources Limited

Locksley Resources Ltd ASX:LKY

Locksley Resources Limited (ASX:LKY) (FRA:X5L) (OTCMKTS:LKYRF) is an ASX listed explorer focused on critical minerals in the United States of America. The Company is actively advancing exploration across two key assets: 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 in this highly prospective mineral region. 

Mojave Project 

Located in the Mojave Desert, California, the Mojave Project comprises over 250 claims across two contiguous prospect areas, namely, the North Block/Northeast Block and the El Campo Prospect. The North Block directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials' claims, highlighting the strong geological continuity and exploration potential of the project area. 

In addition to rare earths, the Mojave Project hosts the historic "Desert Antimony Mine", which last operated in 1937. Despite the United States currently having no domestic antimony production, demand for the metal remains high due to its essential role in defense systems, semiconductors, and metal alloys. With significant surface sample results, the Desert Mine prospect represents one of the highest-grade known antimony occurrences in the U.S. 

Locksley's North American position is further strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE & antimony production. With its maiden drilling program planned, the Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security. 

Tottenham Project 

Locksley's Australian portfolio comprises the advanced Tottenham Copper-Gold Project in New South Wales, focused on VMS-style mineralisation in a well established mining region. 

Locksley is committed to delivering value through discovery, development, and strategic partnerships, with a focus on securing access to U.S. aligned funding and downstream collaborations.
