Metals Australia Ltd (ASX:MLS) has a proven track record of battery minerals discovery and has a high-quality portfolio of advanced battery minerals and metals projects in the highly ranked and well-established mining jurisdictions of Quebec, Canada and Western Australia.
- Major new metallurgical test-work programs are set to commence at the high-grade Lac Rainy flake graphite project in the tier-one Canadian mining jurisdiction of Quebec. The test-work will utilise bulk samples of existing drill-core from the following Mineral Resource1 zones (see Figure 1):
- Southeast Carheil: A 220kg bulk sample grading 13% graphitic carbon (Cg). Sample of predominantly fine to medium flake will be split into several variability samples representing the first 10 years of the mining schedule detailed in the previously completed Scoping Study 2.
- Northwest Carheil: A 200kg bulk sample grading 8%Cg. Examination of drill core from Northwest Carheil indicates a high proportion of large (>180 micron) flake. The metallurgical test-work program for this portion of the Mineral Resource will assess the recovery characteristics of higher value, large flake graphite concentrate.
- Metallurgical test-work will be carried out in two stages:
1. Generation of flake graphite concentrate (>95%Cg) using modified flow-sheet conditions designed to optimise recovery of fine to medium flake for downstream spherical graphite production as well as generation of large flake concentrate that can attract premium pricing.
2. Generation of premium battery grade coated spherical graphite (SpG), trialling chemical and thermal purification options to assess the preferred techno-economic method for production of premium battery grade SpG, followed by lithium-ion battery anode charging and durability testing. This work will expand on the outstanding purification (to 99.96%Cg) and battery test results achieved in 20233 and will result in the optimum SpG production method being adopted for more advanced development studies.
- The Metallurgical test-work results will feed directly into the flake-graphite concentrate Pre-Feasibility Study (PFS) as well as the Options Assessment and Scoping Study into downstream spherical graphite- battery anode material production. Additionally, the results will guide the preferred location for that production facility.
- Latest workstreams will be advanced as the Company finalises discussions with First Nations groups in Quebec to secure the necessary approvals to launch a major new drilling program aimed at significantly expanding and upgrading the existing Lac Rainy Mineral Resource. The program will also test new regional targets where high-grade rock chips of up to 64.3% Cg4 have been generated (see Figure 1). The company is aware of changes to the permitting application process in Quebec that come into effect on May 6th this year. More formal stakeholder engagement is a requirement as part of the revised process.

Metals Australia CEO Paul Ferguson, commented:
“These new metallurgical test-work programs at Lac Rainy represent another important step forward along the very clear pathway we have mapped out to develop what we believe has the potential to be a world-class flake-graphite project in the tier-one Canadian mining jurisdiction of Quebec.”
“The US$50 million equity investment and a future construction commitment of US$275 million5 announced only last month by General Motors and Panasonic Energy to advance the development of Nouveau Monde Graphite Inc’s graphite project in Quebec is another sign of the global rush to secure sources of high-grade flake graphite and downstream products outside China.”
“Building on our Scoping Study which indicates potential for an initial 14-year production mine life, we are committed to accelerating our pre-feasibility studies (PFS) for the production and downstream processing of Lac Rainy’s high-grade flake-graphite product.”
“Other critical work programs being advanced in parallel with our metallurgical test-work include environment and social impact studies, hydrogeological and geotechnical assessments, Mineral Resource estimation work and finalising key inputs to mine planning and engineering design for the concentrate plant PFS and the proposed downstream upgrading facility to produce battery anode material.”
“We have also finalised our drilling plans and contract and look forward to our drilling permit applications being approved by the government authorities in Quebec. The Company has been advised that no adverse comments were provided by stakeholders during the initial public review period for that drilling program and we look forward to our upcoming discussions with representatives of the Innu Council of Uashat Mak Mani- Utenam First Nations group to outline our planned program as part of the approval process.”
“The Company is fully committed to working respectfully and productively with all stakeholders to demonstrate the significance and potential benefits of developing this important critical minerals project, while understanding and accommodating the expectations of stakeholders throughout the development phases.”
“Our drilling program aims to extend and further define the Mineral Resource to allow expansion of the mining plan, as well as testing new regional targets where high-grade rock chips of up to 64.3% Cg4 have been generated. The fact we still have 35km of mineralised zones at Lac Rainy to drill test adds to our confidence that we will be able to significantly grow the existing Mineral Resource.”
“Critically, the recent $3.5 million placement we made through Canadian investors leaves the Company well- funded to accelerate our exploration and development studies with cash reserves of more than $18 million. The fact that Metals Australia’s market capitalisation is less than our cash balance makes us more determined than ever to demonstrate the value of our flagship Lac Rainy project, which we believe will result in a significant re-rating of the Company’s share price.”Click here for the full ASX Release

Investor Insight
Metals Australia offers investors exposure to a rapidly advancing, high-grade graphite development project in Quebec with near-term growth catalysts, backed by strong government support, battery-grade test results, and a diversified portfolio of critical, precious and base minerals assets in tier-1 jurisdictions.
Overview
Metals Australia (ASX:MLS) is a mineral exploration company with a high-quality portfolio of advanced battery minerals and metals projects in tier-1 mining jurisdictions of Western Australia and Canada. The portfolio comprises two critical minerals projects in Quebec, Canada – the Lac Carheil flake graphite project and the Corvette River gold, silver and base metals project. The Australian portfolio comprises two projects: Warrego East (copper-gold) in Tennant Creek, Northern Territory, and Manindi (vanadium-titanium, zinc) in Western Australia.
The push for net zero targets and the call from policymakers to transition to cleaner energy has intensified the focus on electric vehicles (EVs) and battery storage. EV automakers and battery manufacturers rely on essential materials such as graphite and metals, including lithium, nickel, copper and cobalt, to manufacture the batteries that are used in these vehicles and storage batteries generally. This has driven carmakers and battery manufacturers to partner with battery material suppliers under direct off-take agreements. Further, some automakers/battery manufacturers are buying equity stakes in miners, involving them directly in financing decisions for the development of mining projects. This is encouraging for companies such as Metals Australia as it actively advances its projects towards development.
Graphite is a critical mineral required for the mass electrification of auto transportation.
Metals Australia is focused on progressing its flagship Lac Carheil flake graphite project in Quebec, Canada. The project is well-positioned to supply high quality graphite products, including battery-grade graphite, to the North American market – including for lithium-ion and EV battery production in the future. The company has completed a major winter drill program and is targeting a mineral resource upgrade in Q3 2025, with the updated resource to feed into the ongoing PFS and downstream studies.
Metallurgical work has demonstrated battery-grade spherical graphite (99.96 percent graphitic carbon) with high conversion efficiency and tap density. Downstream battery-grade purification and shaping test work is underway in Germany with ANZAPLAN.
Metals Australia is also advancing its gold silver and base metals exploration project at Corvette River, which is adjacent to Patriot Battery Metals’ world-class lithium project. Work to date has included mapping, trenching and sampling, with further drilling programs planned for 2025.
The company continues its exploration programs at its other Australian projects: Manindi (vanadium-titanium-magnetite) and Warrego East (copper-gold).

Key Projects
Canada
Lac Carheil Flake Graphite Project (MLS 100 percent)
The 100 percent owned Lac Carheil graphite project is located in eastern Quebec, a tier-1 mining jurisdiction with strong infrastructure and government support. The project lies near the town of Fermont and has excellent access to power and logistics, including proximity to the upgraded Highway 389, nearby hydropower infrastructure, and an expanding provincial road network.
Project location, claims boundaries, graphite resource & trends, regional magnetics & sample results
The current JORC 2012 mineral resource is 13.3 Mt 11.5 percent total graphitic carbon (Cg) for 1.53 Mt of contained graphite, based on limited drilling along just 1 km of a much larger 36 km mapped trend. The resource includes an indicated resource of 9.6 Mt @ 13.1 percent Cg, and inferred resource: 3.7 Mt @ 7.3 percent Cg.
A major 9,482-meter winter diamond drilling program was completed in early 2025, increasing total project drilling to ~11,800 meters. The program defined a new southeast extension zone with multiple intersections >15 percent Cg and demonstrated graphite continuity over 2.3 km of strike length, more than double the previous extent.
The results from this drilling campaign are being incorporated into an updated mineral resource estimate, expected in Q3 2025, which will underpin the next stage of project development.
Metallurgical and battery test work has confirmed Lac Carheil’s graphite is suitable for battery-grade applications, with:
- Flotation concentrate purity of 97 percent Cg
- Spherical graphite purity of 99.96 percent Cg
- Tap density of 0.97 kg/L
- Anode conversion efficiency of 65.3 percent, exceeding global industry averages
A PFS is being led by Lycopodium Minerals Canada and is progressing in parallel with downstream battery anode (BAM) test work led by ANZAPLAN in Germany, a location study for a BAM facility, likely in Canada, and marketing and pricing assessments in collaboration with Lone Star Technical Minerals.
The project is uniquely positioned to meet North America’s surging demand for secure, domestic graphite supply, especially for EV and energy storage battery markets. It represents a strategic, high-grade, long-life source of critical material, with potential for vertical integration from mine to battery anode material.
Corvette River Gold, Silver and Base Metals Project (MLS 100 percent)
MLS’s Corvette River Project Area’s – Felicie in the northeast, West and East Eade prospects to the south of the Corvette River, 2024 & prior sample result highlights, regional geology - including greenstone belts
The Corvette River gold, silver and base metals project is located in Quebec’s James Bay region. Corvette River comprises multiple prospects including East Eade, West Eade and Felicie. The 2024 program confirmed high-grade gold and base metal zones, with trench samples of up to 29.7 g/t gold. Field programs are ongoing, with follow-up work planned in 2025.
Australian Projects
Manindi Project (MLS 80 percent)
Located in the Murchison District of Western Australia, the Manindi project includes a JORC-compliant zinc-copper-silver resource of 1.08 Mt at 6.52 percent zinc, 0.26 percent copper and 3.19 g/t silver. The project also hosts a high-grade vanadium-titanium-iron (Ti-V-Fe) discovery zone situated adjacent to the base metals resource.
Recent metallurgical test work from the Ti-V-Fe zone has produced two commercially attractive concentrates: a high-grade iron-vanadium product grading 66 percent Fe and 1.19 percent V₂O₅, and a titanium-iron product grading 43.8 percent TiO₂ and 32.0 percent Fe. The combined mass recovery from the two products exceeded 65 percent of the sample, and both products displayed low impurity levels and strong commercial potential. Further processing optimization is underway to enhance the TiO₂ grade.
The mineralised Ti-V-Fe zone remains open at depth and along strike and is hosted within a 2 km-long magnetic gabbro trend. A program of work is being finalised to support drilling to define a mineral resource within the original discovery and to test four newly identified nearby targets. These complements renewed interest in the zinc-copper-silver resource due to stronger base metal prices.
Warrego East Project (MLS 80 percent)
The Warrego East copper-gold project is located in the Tennant Creek region of the Northern Territory, near the historically significant Warrego Mine. The exploration license (E32725) is fully granted, and the mining management plan has been approved. Land access agreements have also been finalised.
Geophysical surveys have defined 11 compelling magnetic and gravity targets along a known mineralised corridor. These targets lie within a prospective structural setting that hosts several high-grade historical deposits. A field program is being prepared for execution following the wet season, alongside three additional tenement applications that aim to expand the project footprint.
