Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to advise that recently completed geological mapping and rock chip sampling at the 100%-owned Red Mountain Lithium Project in Nevada, USA has identified a new zone of lithium bearing clay-rich rocks (shown as the Dark green ‘Unit J’ in Figures 1-3) with lithium grades of up to 2,100ppm lithium.
Key Highlights
- Detailed geological mapping completed by consulting expert Professor Phillip Gans of the University of California Santa Barbara.
- Mapping identifies two priority clay-rich and lithium- hosting rock units at Red Mountain.
- Additional rock-chip sampling within ‘Unit J’ identifies a broad zone of mineralisation grading up to 2,100ppm Li.
- Mapped as the most clay-rich rock type. ‘Unit J’ has only been tested by one drill hole, indicating excellent upside.
- Continuous ‘Unit O’ trending approximately north-south through project will underpin the upcoming Exploration Target.
Unit J is a claystone and siltstone dominated rock type located in the west of the Red Mountain Project area which was identified as part of detailed geological mapping undertaken by consultant geologist Professor Phillip Gans of the University of California Santa Barbara. Professor Gans identified Unit J as the most clay-rich rock unit at the Project and recommended a targeted sampling campaign to establish the presence of lithium mineralisation. Subsequently a total of 38 sub-crop and outcrop samples were taken over an area of 800 x 500m of Unit J (Figure 1), with excellent assay results returned from 13 samples grading 1,000ppm lithium or greater. The sampling revealed outstanding exploration potential in this previously unsampled part of the project.
The mapping also identified two priority rock units for future drill targeting – Unit O and the previously mentioned Unit J. Unit O (shown in pale green in Figures 1-3) is dominated by silt and sandstone with clay-rich horizons, is interpreted to be continuous over a 7.8km extent across the Project, and has been tested by 12 of the 13 holes drilled to date, each of which has intersected strong lithium mineralisation7.
The continuous nature of Unit O will underpin a maiden Exploration Target for the Project and inform the drill targeting strategy for the first half of 2025, as the Company advances toward a Maiden Mineral Resource Estimate in the second half.
Astute Chairman, Tony Leibowitz, said:
“With the advice of expert independent consultants, we are continuing to systematically progress the Red Mountain Project. The identification of a new high-grade lithium-bearing unit increases the project’s potential, while the enhanced geological understanding allows the calculation of an Exploration Target, as well as contributes to de-risking of the upcoming drilling campaign, paving the way for a maiden Mineral Resource Estimate in the second half of 2025”

Background
Located in central-eastern Nevada (Figure 4), adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional mining towns of Ely and Tonopah. the Red Mountain Project was staked by Astute in August 2023.
The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation2. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 4) such as Lithium Americas’ (NYSE: LAC) 62.1Mt LCE Thacker Pass Project2 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project3.
Astute has completed substantial surface sampling campaigns at Red Mountain, which indicate widespread lithium anomalism in soils and confirmed lithium mineralisation in bedrock with some exceptional grades of up to 4,150ppm Li1,6 (Figures 1 and 3).
A total of 13 RC and diamond drill holes have been drilled at the project for a combined 1,944.72m. Both campaigns were highly successful with strong lithium mineralisation intersected in every hole drilled7.
Scoping leachability testwork on mineralised material from Red Mountain indicates high leachability of lithium of up to 98%, varying with temperature, acid strength and leaching duration8.

The Munda Starter Pit Mining Proposal and Mine Closure Plan have been approved by the WA Government’s Department of Energy, Mines, Industry Regulation and Safety (DEMIRS).
Survey mark-out of the pit crest, haul road, waste dump, ROM pads and site office has been completed.
Auric has executed a contract to dry hire the mining fleet from MHM Contracting Pty Ltd. The fleet will be operated by Auric employees.
A grade control program over the Starter Pit extents for those holes accessible from surface on a 5m x 5m pattern has also been completed. A total of 428 holes for 14,670m were drilled by Kalgoorlie-based Total Drilling Services. Results have been received allowing the mine geologists to define near surface ore blocks in advance of mining. Further grade control drilling on a 5m x 5m pattern will be undertaken as mining exposes new benches.
The Company will commence mining the Starter Pit this week, where it is estimated 125,000 tonnes of ore will be extracted at an estimated grade of 1.8g/t Au at an AISC of A$2,635 per ounce (Tables 2 and 3). The Starter Pit will take approximately six months to complete.

Optimised Root Lithium Project PEA Highlights Robust Economics
HIGHLIGHTS
- The Root Lithium Project in Ontario, Canada has been evaluated on a standalone basis and considering the recently updated Root Project MRE, revised pit optimisations and mine development options and changed lithium market conditions (previous 2023 PEA results were combined with the Company’s Seymour Lithium Project also in Ontario)
- The study confirms favourable economics across alternative mine development scenarios, including both open pit and underground mining, reinforcing Root as a viable and resilient standalone project
- The selected development option for the Root Lithium Project delivers:
- An increase in NPV to US$668 million
- A reduction in pre-production CAPEX, largely due to lower pre-stripping costs
- Reduction in Total Material Movement (TMM)
- Lower NPV and longer payback period due to more conservative SC5.5 pricing assumptions in early processing years
- Significantly improved LOM strip ratio of 8.1:1, driven by underground development—resulting in lower mining costs that help offset reduced revenues
PROJECT DASHBOARD
- The Root Lithium Project underpins GT1’s vertically integrated development strategy and is expected to provide long-term feed to the Company’s planned Lithium Conversion facility in Thunder Bay
- The immediate focus for the Root project will be advancing permitting and consultation activities in parallel with the Pre-Feasibility Study( PFS)
"The completion of the optimised PEA marks a major milestone for the Root Lithium Project, confirming it as a technically and economically robust standalone operation. With a longer mine life, reduced upfront capital requirements, and strong economics, Root is well-positioned to support GT1’s broader strategy of establishing a vertically integrated lithium supply chain in Ontario. This study reinforces our confidence in Root as a long-term feed source for the Thunder Bay conversion facility and highlights the project’s strategic importance in the North American battery materials landscape.
The economic advantages of executing a project in Ontario are obvious and compelling, driven by outstanding infrastructure, government incentives and proximity to the North American EV supply chain. We remain committed to advancing our Root Lithium Project to realise our overall strategy in Ontario.”
-GT1 Managing Director, Cameron Henry

Bayan Secures Transformative Patents in Solar Cell Recycling Technology
- Bayan has secured an exclusive license from Macquarie University for “Microwave Joule Heating Technology” a microwave-based solar panel recycling technology, positioning the company at the forefront of sustainable energy technology solutions.
- The Company intends to commence further research and development to assess the ability to potentially recover valuable metals such as Silver, Silicon, Gallium and Indium.
- The basis of the technology platform utilises microwave technology to soften the EVA encapsulant in solar panels, enabling easy delamination and potential recovery of valuable materials at room temperature. This approach avoids the need for extreme heat (1400°C) typically required for separating materials like glass and silicon as well as the use of costly hazardous chemicals in traditional processes.
- Delamination enables selective separation of materials without the need for mechanical crushing, whereas traditional crushing methods often result in crosscontaminated material and lower recovery rates.
- The breakthrough technology presents a potential novel pathway for improved recovery of materials such as silver and silicon from solar panels, critical materials underpinning solar and semiconductor technologies.
- By 2035, Australia is expected to accumulate 1 million tonnes of solar panel waste worth over A$1 billion1, while the global CIGS (Copper, Indium, Gallium, Selenide) solar cell market is projected to grow to US$12.23 billion by 20322.
The Technology from Macquarie University
The team from the School of Engineering at Macquarie University, led by Dr Binesh Puthen Veettil, have developed a new microwave technology that will solve the challenge of electronic waste from end-of-life solar panels. Currently, the recycling process is technically challenging with only an estimated 15% of solar panels making it to a recycling facility3, and the remainder going straight to landfill once they have reached their 20–25-year end of life span. In the rare instance they are recycled, the solar panels, in the traditional method, are crushed and heated at approximately 1400°C before being washed in harsh chemicals to remove the plastics.
Dr Binesh Puthen Veettil’s research in collaboration with the School of Photovoltaics at UNSW, the Australian Centre for Advanced Photovoltaics and further supported by the Australian Government through the Australian Renewable Energy Agency highlights the immense need and impact this technology will bring.
In this new method, the microwave energy is used to selectively heat the materials within a solar panel. In this process, the silicon cells and other microwave-absorbing components rapidly heat up, while surrounding materials remain relatively cool. This targeted heating causes the plastic encapsulant, ethylene vinyl acetate (EVA), which holds the panel layers together to soften and degrade.
