‘ While these results represent the early stages of testing in a geologically complex corridor, their significance lies in extending our knowledge of mineralization continuity between the historic Brenbar and Sturgeon River Mine areas, ‘ stated Cynthia Le Sueur-Aquin, President and CEO of LAURION. ‘This is the first time drilling has been completed across this untested structural corridor, and it is yielding valuable geological insight with oriented core, that will guide the next phase of our exploration program. Our focus remains on defining the broader mineralized system that links multiple historic mine zones, ultimately positioning Ishkōday as a district-scale gold and base metal opportunity.’

Table of Assays for Drill Holes for LME25-063 to LME25-066

Note: (Intervals represent core length. The interval widths reported are down-hole widths. The true widths of the mineralized zones are not known at this time as there is insufficient information to determine the orientation of the mineralization. True widths are estimated at ~70–90% of reported intervals.)

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkõday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QAQC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkõday Project.

Perth, Australia (ABN Newswire) – Altech Batteries Limited (ASX:ATC,OTC:ALTHF) (FRA:A3Y) (OTCMKTS:ALTHF) announced a significant and strategically important development in its Silumina Anodes(TM) project, following formal engagement initiated from a leading global battery manufacturer and one of the world’s largest electric-vehicle battery manufacturer (‘Battery Group’). The Battery Group approached Altech expressing strong interest in the Company’s proprietary high-performance silicon-enhanced anode technology. This unsolicited approach represents a major validation of the technical progress achieved by Altech and underscores the growing global recognition of the breakthrough potential of its alumina-coated silicon innovations.

Following initial discussions, a mutual Non-Disclosure Agreement (NDA) was executed to enable the confidential technical exchange and evaluation of materials. As part of this collaboration, Altech has prepared and supplied Silumina AnodesTM samples to the Battery Group. These samples, developed under the leadership of Altech’s Chief Technical Officer Dr Jingyuan Lui, have now been shipped to the Battery Group for formal testing in their advanced battery-evaluation laboratories in China.

The Battery Group’s team, during preliminary discussions, indicated that across the industry they have not yet seen silicon additions deliver such meaningful performance improvements at low percentages.

Traditionally, attempts to integrate silicon into commercial lithium-ion anodes have been challenged by expansion-related degradation, unstable solid-electrolyte interphase (SEI) formation and rapid cycle-life fade. The strong performance of Altech’s coated silicon, achieved with only modest silicon loading, was highlighted as particularly noteworthy. The Battery Group acknowledged that very few material suppliers globally are producing silicon additives with this level of stability, consistency, and real-world applicability.

This early feedback reinforces the technical advantage and disruptive potential of Altech’s process.

The Battery Group has also requested that Altech undertake coating trials on their supplied graphite material to assess the performance impact of integrating Altech’s proprietary alumina technology directly onto their own anode substrate. Under the NDA, the Battery Group has dispatched several kilograms of representative graphite samples to Altech’s Perth laboratory, where Dr Lui’s team will apply the Company’s coating process and prepare evaluation batches. These coated graphite samples will then be returned to the Battery Group for benchmarking against their internal standards, providing a direct comparison of how Altech’s technology enhances their preferred graphite formulations.

UPDATE OF LONG CYCLE SILUMINA TESTING

Altech announced on 9 October 2025 a major advancement in its Silumina Anodes(TM) project, achieving the strongest battery-cycling performance recorded to date for its proprietary alumina-coated spherical silicon anode material. Since that announcement, the latest test results now demonstrate an impressive 83% capacity retention after 1,000 charge-discharge cycles with a 5% Silumina Anodes(TM) addition to a standard graphite anode. This represents a significant milestone for the Silumina Anodes(TM) technology, confirming both its durability and real-world commercial potential. Importantly, such cycle-life performance places Altech’s material at the forefront of next-generation silicon-enhanced anode technologies, strengthening its position in the rapidly evolving global battery materials market.

HOW SILUMINA ANODES(TM) IS MADE

Altech’s spherisation process transforms irregular silicon particles into perfectly rounded, alumina-coated spheres that integrate seamlessly within graphite anodes. The process begins with submicron silicon powders that are uniformly coated with a nanolayer of high-purity alumina, buffering against volume expansion during lithiation. These coated particles are then spherified through a precision-controlled thermal and mechanical process that rounds their geometry (refer Figure 1*). When blended into the graphite matrix, the spherical Silumina AnodesTM particles naturally occupy microscopic voids, where they can expand and contract freely during cycling without damaging the surrounding structure (refer Figure 2*). This optimised configuration mitigates mechanical stress, maintains electrode integrity, and enhances electrical connectivity. With only a 5% addition, the design achieves >40% capacity boost while preserving exceptional cycle stability over extended use.

Altech’s Managing Director Iggy Tan stated ‘This engagement from the world’s largest battery manufacturer is a powerful validation of our Silumina Anodes(TM) technology. Their early feedback, particularly noting they have not seen silicon additions perform this effectively at such low levels, reinforces the significance of our breakthrough. We are excited to advance this collaboration under the NDA and look forward to demonstrating how Altech’s coating technology can further enhance their graphite and anode performance.’

About Locksley Resources Limited:

Locksley Resources Limited (ASX:LKY,OTC:LKYRF) (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.
