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.

HIGHLIGHTS:

• 83.2m grading 17.35 g/t gold from 76.0 m, including
  • 46.65 m grading 27.35 g/t gold from 88.95 m
• 70.7m grading 9.38 g/t gold from 49.65 m
• 92.1 m grading 4.33 g/t gold from 97.1 m
• 65.2 m grading 5.39 g/t gold from 152.2 m
• Ana Paula drill program to be extended to 20,000 metres of drilling

Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) is pleased to announce additional results from the current drill program at its 100% owned Ana Paula project in Guerrero, Mexico. The program aims to convert inferred ounces to higher confidence classifications. It will also support the ongoing Feasibility Study and testing the next exploration targets around the Ana Paula deposit.

Heliostar CEO, Charles Funk, commented, ‘It’s rare to find a deposit that consistently produces 50-100m wide drill intercepts of these gold grades. Ana Paula is wide, high-grade, and shallow, with good underground mining conditions. These factors drive the low $1,011 all in sustaining cost in our new PEA for the project. It will also drive high margins at the project. The current program is focused on upgrading inferred ounces to higher confidence categories and the new data will be incorporated into a Feasibility Study. The lower costs drive a lower cut-off grade in the planned mine that opens the potential for more inferred material conversion. To maximize this opportunity, we will expand the program by 33% to 20,000 metres to allow for more infill and exploration drilling at Ana Paula. Across the Company, we have another study, a Prefeasibility Study for Cerro del Gallo, planned this quarter. We are also drilling at San Agustin and La Colorada. These programs should increase production and unlock the value we see in our deep growth portfolio.’

Drilling Program

Heliostar has completed 44 holes and 12,615 metres drilled to date. Drilling is designed along north-south sections with angled holes to better define the overall east-west orientation of the High Grade Panel. Heliostar’s drilling approach at Ana Paula has been to change the direction of drilling by approximately 90 degrees from the majority of historic intercepts. The Company believes that this change contributed to demonstrating more continuous and higher-grade gold mineralization within the High Grade Panel than recognized by previous operators.

Where appropriate, the holes are also being used to collect rock strength data, hydrogeologic data and samples for further metallurgical studies that will directly influence the Ana Paula mine design in the ongoing Feasibility Study.

Drill Results Summary

Holes AP-25-331, AP-25-333, AP-25-334 and AP-25-336 are resource conversion holes drilled in the central part of the High Grade Panel. Holes AP-25-334 and AP-25-336 were drilled on the same fence, with AP-25-334 targeting the polymictic breccia and hanging wall mineralization, and AP-25-336 targeting the polymictic breccia and footwall mineralization. Hole AP-25-334 intercepted a wide zone of 92.05 metres (‘m’) grading 4.33 grams per tonne (‘g/t’) gold, whilst AP-25-336 returned intervals of 3.2 m at 15.58 g/t gold, 65.15 m at 5.39 g/t and 43.55 m at 4.66 g/t gold with a 3.05 m interval with 24.64 g/t gold.

Hole AP-25-333 is located 60 m to the east of the above-mentioned fence and returned two high-grade intervals of 26.6 m grading 4.78 g/t gold and 83.2 m grading 17.35 g/t gold. Hole AP-25-331 is a step out 32 m to the southeast and returned a 7.95 m zone grading 7.92 g/t gold and a wide high-grade interval of 70.65 m at 9.38 g/t gold.

Holes AP-25-330, AP-25-332 and AP-25-335A are geotechnical holes for mine development planning and returned assay results in line with expectations, including intervals of 48.5 m of 5.48 g/t gold, 5.2 m of 4.23 g/t gold and 35.55 m of 6.73 g/t gold, respectively.

True widths are unknown. Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks.

Drilling continues throughout the High Grade Panel and its less well-defined east and west edges, with assays pending from twelve holes. Two of the drills have begun to target deeper inferred mineralization and the northern exploration zone, which is approximately 250 m north of the High Grade Panel that has two drill holes pending assay.

The next Ana Paula drill results are anticipated to be released in December.
