Two Lithium Zones Confirmed in Latest Drill- Hole at Red Mountain Project, USA

Result supports Exploration Target, successfully intersecting lithium under cover

Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to report assay results from the second hole of its April 2025 diamond drilling campaign at the 100%-owned Red Mountain Lithium Project in Nevada, USA.


Key Highlights

  • Diamond drill-hole RMDD005 intersected two zones of lithium mineralisation under alluvial gravel, returning:
    • 9.1m @ 1,350ppm Li from 57.9m, within a broader low- grade zone of 80.8m @ 860ppm Li from 12.2m;
    • 8.3m @ 1,210ppm Li from 240.8m to end-of-hole, within a broader zone of 15.9m @ 955ppm Li from 233.2m to end-of-hole
  • RMDD005 is the first drill-hole at Red Mountain to successfully intersect ‘blind’ mineralisation.
  • Hole ended in lithium mineralisation, with the mineralised zone remaining open down-dip to the east and along strike.
  • Assays pending from four other recently completed drill- holes.

Drill-hole RMDD005 returned two intersections of lithium mineralisation:

  • 80.8m @ 860ppm Li / 0.46% Lithium Carbonate Equivalent1 (LCE) from 12.2m, including an internal high-grade zone of 9.1m @ 1,349ppm Li / 0.72% LCE from 57.9m;
  • 15.9m @ 955ppm Li / 0.51% LCE from 233.2m to end-of-hole, including an internal high- grade zone of 8.3m @ 1,209ppm Li / 0.64% LCE from 240.8m to end-of-hole.

Drill-hole RMDD005 is the first hole at Red Mountain to test for mineralisation interpreted as part of the recently announced Exploration Target (ASX release 12 February 2025) under significant alluvial cover (Figures 2 and 3). The hole was designed to test the lower extent of mineralisation in the eastern zone of Target Area A, before passing through a zone of unmineralised rocks, and then testing a second, western zone of interpreted mineralisation (see Figure 2). The hole successfully intersected both interpreted zones of mineralisation, separated by a weakly mineralised sequence of mostly conglomerate and breccias.

This result reinforces the Company’s understanding of lithium mineralisation at Red Mountain, providing further confidence in the geological model as work programs continue to progress. The more moderate grades intersected in RMDD005, which was located centrally within the project area, also lend support to the Company’s emerging interpretation that the northern part of the Red Mountain Project is likely to host a high-grade zone of lithium mineralisation.

Assays are pending for a further four holes drilled as part of the April diamond drilling campaign, which are expected to be received by the end of the financial year.

Astute Chairman, Tony Leibowitz, said:

“The results from this latest hole at Red Mountain are very encouraging, intersecting lithium mineralisation under cover exactly where the technical team expected it to be. This provides increased confidence in the geological model that underpins the Red Mountain Exploration Target as we rapidly advance towards the planned delivery of a maiden JORC Mineral Resource Estimate later this year.

“Our exploration at Red Mountain to date indicates significant scale potential, with lithium mineralisation confirmed over a strike length of almost 6 kilometres. This latest drilling is continuing to firm-up these results and reduce risk, successfully intersecting lithium between holes to delineate an increasingly robust and coherent body of mineralisation.”

Perth, Australia (ABN Newswire) - Locksley Resources Ltd (ASX:LKY) (OTCMKTS:LKYRF) is pleased to announce the appointment of Mr Pat Burke as Non-Executive Chairman. Mr Burke brings proven experience and success in advancing rare earth element (REE) projects and has significant corporate governance expertise, ASX listed leadership experience and a strong track record in the resources sector.

In his role as Executive Chairman of Meteoric Resources NL (ASX:MEI), MC ~$370m, he oversaw the transformative acquisition and advancement of the Caldeira ionic clay REE project in Brazil, one of the world's largest high grade ionic clay rare earth deposits. Mr Burke was actively involved in all aspects of the project's initial progression, including negotiations with government agencies, local partners and funders.

He is a qualified lawyer, with over 20 years legal and corporate advisory experience. Mr Burke's legal expertise is in corporate, commercial and securities law. His corporate advisory experience includes identification of acquisition targets, deal structuring and financing and project development.

He has held Board roles across numerous ASX companies, as well as AIM and NASDAQ-listed companies, including Mandrake Resources and Vulcan Energy Resources.

Locksley is entering a significant growth phase as it advances its Mine to Market Strategy. In conjunction with Mr Burke's appointment, Mr Nathan Lude will transition from Chairman to the newly created role of Head of Strategy, Capital Markets & Commercialisation. This reflects the Company's focus on advancing its U.S. minerals projects, processing pathways and downstream critical minerals and technology initiatives. In this role Mr Lude will dedicate his time to:

Downstream Technology & Commercialisation

- Coordinating Locksley's collaboration with Rice University to fast-track antimony extraction, processing and energy storage innovation

- Securing commercial licensing opportunities, pilot site identification, and deployments

- Driving the establishment and contributions of Locksley's U.S. subsidiary and Advisory Board

Strategic Partnerships & Government Engagement

- Building strategic partnerships and alliances with U.S. defense, energy, and targeted technology sectors

- Coordinating engagement through GreenMet, including submissions to U.S. federal and state government programs and funding opportunities such as the DOE, DoD, and EXIM Bank

Capital Markets & Investor Growth

- Overseeing marketing, investor relations, and public relations

- Assessing growth pathways to OTCQX, NASDAQ, SPAC structures, and Frankfurt listing

Mr Lude commented:

"Locksley has rapidly advanced its growth strategy in recent months, advancing both upstream project development and new downstream opportunities. This change allows me to focus on our Mine to Market initiatives in the U.S., where our projects and partnerships can meaningfully strengthen America's critical minerals supply chain. With Pat leading the Board, drawing on his experience and success in identifying and advancing the Meteoric REE opportunity and his deep industry knowledge on critical minerals, I can dedicate my time to building the business foundations for Locksley's next phase of investor growth."

Mr Burke commented:

"Locksley's integrated approach from resource development through to downstream processing and advanced applications is well aligned with the current U.S. focus on secure, strategic critical minerals supply chains. I look forward to working with the Board and management to advance the Company's portfolio and deliver value for shareholders."



About Locksley Resources Limited:

Locksley Resources Limited (ASX:LKY) (OTCMKTS:LKYRF) 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.

Mojave Project

Located in the Mojave Desert, California, the Mojave Project comprises over 240 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 surface samples grading up to 46% Sb as well as silver up to 1,022 g/t Ag, 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.
