Nouveau Monde Graphite Matawinie mine: project and supply-chain notes for engineers
Reviewed by Tom Sullivan

30 Second Briefing
Construction has begun on Nouveau Monde Graphite’s C$2 billion Matawinie mine in Québec, fast-tracked through Canada’s Major Projects Office and designed to produce up to 106,000 tonnes of graphite per year, which would make it the largest graphite mine in the G7. Ottawa has backed the project with financing from Export Development Canada, the Canada Infrastructure Bank and the Canada Growth Fund, plus a seven-year offtake for 30,000 tonnes of concentrate annually. The mine, 120 km north of Montreal, is expected to create over 1,000 jobs and anchor an integrated graphite-to-battery materials chain with NMG’s planned Bécancour plant.
Technical Brief
- Federal referral to the Major Projects Office was completed in only six months, materially compressing pre-construction timelines.
- Ottawa support includes Export Development Canada, Canada Infrastructure Bank and Canada Growth Fund financing tranches, de-risking project capex.
- A seven-year federal offtake secures 30,000 tonnes per year of graphite concentrate, underpinning revenue certainty for lenders.
- NMG is advancing Phase 2 as an integrated mine–to–battery-materials strategy, linked to the planned Bécancour processing plant.
- Recent release of C$96.5 million from escrow improves near-term liquidity for early works and long-lead procurement.
- Natural Resources Canada data show Canada produced 12,000 tonnes of graphite in 2024, only 0.7% of global supply.
- China’s 79.4% share of global graphite output, versus Madagascar’s 5.6%, frames the supply-concentration risk this project targets.
- Project is positioned to supply North American battery, defence and advanced manufacturing sectors seeking non-Chinese graphite sources.
Our Take
Matawinie’s fast-tracking through the new Major Projects Office contrasts with earlier coverage of the MPO’s two‑year target for ‘conditions documents’, signalling that critical minerals like graphite in Quebec may now see materially shorter federal permitting timelines than bulk commodities such as potash or gold.
Across our database, NMG is one of the few Canadian graphite players with both substantial public‑backed project debt (EDC and Canada Infrastructure Bank) and strategic equity from an oil and gas major (Eni), which likely improves bankability for downstream offtakers in the US and other G7 markets looking to diversify away from China’s ~80% supply share.
