Metals Australia’s $2.05B Baie‑Comeau graphite refinery: project and IRR lens for engineers

30 Second Briefing
Metals Australia plans a C$2.05 billion high‑purity graphite refinery near Baie‑Comeau, Quebec, designed to process 75,000 tonnes per year of flake graphite concentrate into 51,000 tonnes of battery‑grade products over a 25‑year life, with a projected 25.6% internal rate of return and 227 permanent jobs. Feedstock will come from its Fermont project averaging 10.2% graphite, about 2.4 times higher grade than publicly reported for Nouveau Monde Graphite, and the site leverages rail‑ferry links plus a deep‑water port. The company will bypass a traditional PFS, moving directly to final feasibility while running parallel community and Indigenous engagement to meet Canada’s 2040 graphite mine and refinery targets.
Technical Brief
- Preliminary assessment forecasts more than C$2 billion in total economic value from the Baie-Comeau refinery.
- Direct wage bill is estimated at C$21.5 million per year for the local workforce.
- Baie-Comeau site selection hinged on existing rail–ferry links integrated with deep‑water port access.
- Nine additional undrilled graphite zones over 33 km at Fermont provide upside for long‑term feed security.
- Metals Australia will advance straight from PEA to final feasibility, omitting a conventional PFS phase.
Our Take
A 25.6% IRR on a US$2.05 billion graphite refinery in Baie-Comeau would place Metals Australia at the aggressive end of project economics in our mining database, signalling strong assumed pricing or cost advantages relative to other graphite entries.
Canada’s stated goal of five graphite mines and five refineries by 2040 means this Baie-Comeau facility alone could account for a significant share of the national refining target, likely giving it leverage in securing federal and Quebec critical-minerals support.
The 10.2% average graphite grade near Fermont, at 2.4 times a competitor benchmark, suggests upstream feedstock for Baie-Comeau could sit in the lower half of the cost curve, which is important as our graphite coverage increasingly highlights margin pressure from Chinese anode material producers.
