Metals Australia strengthens Quebec graphite development case

Lac Carheil moves from resource story to development case

Metals Australia Ltd (ASX:MLS) has put a more defined development case around its Lac Carheil graphite project in Quebec, reporting a 50.0 Mt mineral resource grading 10.2% total graphitic carbon and containing 5.1 Mt of graphite. The project now also has a maiden probable ore reserve of 21.51 Mt at 11.14% graphitic carbon, containing 2.40 Mt of graphite and supporting an initial 24-year mine life in the company’s prefeasibility study.

The resource remains larger than the reserve, with 25.2 Mt classified as inferred. Metals Australia says drilling has covered only about 2.3 km of one of 10 mapped and sampled graphite trends, which together extend for more than 36 km. That leaves exploration upside in the company’s model, but the report also notes that mineral resources not converted to reserves have not demonstrated economic viability.

Upstream study points to AUD 572 million after-tax NPV

The upstream PFS covers an open-cut mine and flake graphite concentrate plant near Fermont. It models average annual production of 101,241 tonnes of concentrate at 95.4% TGC over 24 years, with a pre-tax NPV-8 of AUD 790.8 million, an after-tax NPV-8 of AUD 572.0 million, a 22.0% internal rate of return and a 4.2-year payback.

Capital expenditure is estimated at USD 346.3 million, including a USD 40 million contingency. Metals Australia says Canadian Clean Technology Manufacturing Investment Tax Credits of up to USD 96.7 million could reduce effective project capital to USD 249.6 million. The base case uses a weighted average concentrate price of USD 1,385 per tonne, while a USD 1,500 per tonne sensitivity lifts the after-tax NPV-8 to USD 493 million and the IRR to 24.8%.

Refinery economics add a larger but later ambition

The downstream Battery Anode Material refinery assessment is the more ambitious part of the development plan. The PEA models three modular stages processing 75,000 tonnes a year of concentrate into about 51,000 tonnes of battery anode material annually, with production targeted to commence in 2030. Its base case produces a pre-tax NPV-8 of USD 2.05 billion, or AUD 2.93 billion, an after-tax NPV-8 of USD 1.39 billion, or AUD 1.98 billion, and a 25.6% IRR.

The refinery’s estimated capital cost is USD 883.8 million, including contingency, with modelled payback within 4.5 years. A separate pricing sensitivity from Lone Star Technical Minerals increases the after-tax NPV-8 to USD 1.732 billion and the IRR to 28.7%, compared with the Fastmarkets base case. Those figures are PEA outputs rather than construction-ready forecasts, and remain exposed to financing, permitting, construction, operating and graphite-price assumptions.

Cash position leaves funding as the immediate constraint

The financial statements underline the distance between a compelling project model and an operating mine. Metals Australia recorded an AUD 1.512 million net loss for the year, used AUD 3.975 million on exploration and acquisitions, and held AUD 3.733 million in cash at 30 June 2026. The company does not generate operating revenue from mining and explicitly says advancing its projects may require additional equity or debt funding.

Exploration and evaluation assets rose to AUD 28.740 million, while the company continued work across its Australian portfolio. At Manindi West, 13 of 14 discovery-zone holes intersected thick magnetite-ilmenite mineralisation, with the zone extending beyond 1,000 metres of strike and reported widths of 75 to 95 metres. At Warrego East, drilling produced broad, highly anomalous copper, bismuth, cobalt and zinc results, which Metals Australia interprets as consistent with a possible deeper ironstone-hosted system, but neither project has yet displaced Lac Carheil as the company’s central development proposition.
