Metals Australia advances $3.72 billion Lac Carheil project toward feasibility

Lac Carheil economics move into the feasibility test

Metals Australia Limited (ASX:MLS) is trying to turn a striking study-stage valuation into a bankable project. Its integrated Lac Carheil graphite development in Québec generated a reported pre-tax NPV8 of A$3.72 billion and post-tax NPV8 of A$2.56 billion across an upstream mine and concentrate plant and a downstream battery anode material refinery. Those figures come from a prefeasibility study and a preliminary economic assessment, rather than a definitive feasibility study, leaving technical validation, permitting, financing and construction decisions ahead.

The project is designed to produce about 101,241 tonnes a year of flake graphite concentrate, with roughly 75,000 tonnes feeding a refinery planned to produce about 51,000 tonnes of battery anode material annually. Metals Australia says the 21.51Mt probable ore reserve supports an initial 24-year mine life. The company’s Lac Carheil study milestones had previously established the 50Mt graphite resource and study-stage economics now being carried into the next phase.

Metallurgy and permitting remain on the critical path

During the quarter, SGS Canada began Phase 1 metallurgical testing on more than 1.5 tonnes of representative ore from the reserve. The work is intended to improve graphite recovery and flake preservation, assess impurity-removal technologies and examine tailings options. A planned pilot program would then support equipment sizing and generate concentrate for product qualification and downstream studies.

Environmental field surveys covering watercourses, wetlands, fish habitat, small mammals and proposed infrastructure corridors also began. Metals Australia said the results will support project-notice documentation expected in early 2027 and the eventual environmental and social impact assessment. Community and First Nations engagement has continued around Fermont, Baie-Comeau and Pessamit, while the company has submitted a project execution plan under a US Department of Defense critical-minerals program. The filing cautions that the application may not receive final endorsement or funding.

Manindi adds a second critical-minerals development option

In Western Australia, Metals Australia is building a separate development case around Manindi West. The maiden JORC Inferred Mineral Resource stands at 45.7Mt grading 9.4% titanium oxide, 0.25% vanadium pentoxide and 21% iron, within a conceptual 67Mt to 89Mt Exploration Target. The company’s Manindi VTM resource was previously reported alongside test work indicating titanium oxide purity above 99%, but the resource remains Inferred and the Exploration Target is not a Mineral Resource.

Metallurgical testing produced a titanium oxide product grading more than 99.05% TiO₂ from ilmenite-rich material, alongside earlier concentrate work. Metals Australia is also assessing the nearby 1.08Mt zinc-copper-silver resource through possible standalone development, integration with the VTM project, ore sales, partnerships or divestment. None of those commercial pathways has been selected.

Cash position sharpens the funding question

The quarter ended with A$2.575 million in cash after A$0.879 million of exploration and feasibility expenditure, including A$866,000 of capitalised exploration and evaluation payments in the Appendix 5B. On the company’s calculation, available funding covered about 2.25 quarters of relevant outgoings, with no financing facilities disclosed. Metals Australia is awaiting Québec tax-credit assessments and expects eligible exploration and study spending could attract recoveries of up to 45%, but those anticipated refunds and government funding applications are not yet cash in hand.
