Nouveau Monde to Proceed with G7’s Biggest Graphite Mine

Why It Matters

Matawinie will dramatically expand North American graphite supply, reducing reliance on Chinese imports and strengthening the EV and energy‑storage value chain. The project also advances Canada’s critical‑minerals agenda and creates high‑skill jobs in the region.

Key Takeaways

• $644.5M raised for Matawinie mine and battery plant
• Mine will produce 106,000 tonnes graphite annually
• Project will boost Canada's global graphite share to 6%
• 30‑month build schedule targets 2028 commercial production
• 75% of output already under offtake contracts

Pulse Analysis

The global race for battery‑grade graphite has been dominated by China, which controls roughly 80% of mined supply. As electric‑vehicle sales accelerate and energy‑storage deployments expand, automakers and grid operators are scrambling for secure, non‑Chinese sources. Canada, with its abundant hydro‑electric power and stable regulatory environment, is uniquely positioned to fill this gap, and the Matawinie project could become the linchpin of a North‑American supply chain that supports both civilian and defense applications.

Matawinie’s development reflects a rare convergence of financing, policy support, and market demand. The company secured $213.2 million from the Canada Growth Fund, Investissement Québec and Italy’s Eni, complemented by a $96.5 million public offering and debt from Export Development Canada and the Canada Infrastructure Bank. The total capital stack of about $634 million—well below earlier feasibility estimates—covers a 30‑month construction phase, after which the mine will deliver 106,000 tonnes of graphite concentrate annually. With 75% of that volume already contracted and an additional 15% under negotiation, revenue visibility is strong, and the associated Bécancour plant will convert concentrate into anode‑grade material for EV batteries.

Strategically, Matawinie bolsters Canada’s critical‑minerals roadmap, aiming to lift the nation’s share of global graphite output from roughly 1% to 6%. The seven‑year offtake agreement with the federal government, guaranteeing 30,000 tonnes per year at a fixed North‑American price, signals confidence in domestic supply and offers a hedge against geopolitical risk. As the EV market recalibrates after recent demand dips, the project’s scaled‑back plant design preserves flexibility while still delivering a domestic source that could attract further downstream investment, cementing Canada’s role in the emerging green‑energy economy.
