Five things to know about Quebec graphite mine added to major projects list

A graphite mine in Quebec has been included on the federal government’s expanded list of major projects in the national interest to be considered for regulatory fast-tracking.

Here are five things to know about Nouveau Monde Graphite’s Matawinie Mine.

Two facilities

The project includes the company’s future open-pit Matawinie Mine in the Lanaudière region, about 120 kilometres north of Montreal, which plans to produce 106,000 tonnes per year of graphite concentrate over 25 years. The raw materials will be transformed into spherical graphite at a battery plant the company plans to build in Bécancour, Que., near Montreal.

Why it made the list

Dominic LeBlanc, minister of intergovernmental affairs, says that once operational the mine will supply Canada and its allies with a critical mineral used for electric vehicle batteries, energy storage systems, and defence. Nouveau Monde CEO Eric Desaulniers says graphite has more than a dozen other uses, including for advanced polymers and thermoplastics. The federal government already signed a binding term sheet with the company to buy some of the mine’s future output for Canada and allied countries.

Nouveau Monde isn’t the only critical mineral project on the list. A proposed tungsten mine in Sisson Brook, N.B., is to produce the exceptionally strong metal used in energy storage as well as steel production for military and mining equipment.

What the announcement means

Once a project is referred to the Major Projects Office, it is reviewed and returned with recommendations to the government, which has the final say on whether to give it the national interest designation. That designation would permit a project to be streamlined through federal regulatory approval. Desaulniers says the projects office can help the company cover the “last kilometre” before construction can begin by helping to co-ordinate between different stakeholders. The mine’s inclusion on the list also sends a signal of support that can help the company secure financing for construction, he said.

Desaulniers says the company is ready to start building in early 2026, with production beginning some two years later.

Indigenous agreement

The company announced in late 2024 that it had signed an impact benefit agreement with the chief and council of the Atikamekw of Manawan, on whose ancestral territory the mine sits. That agreement includes Atikamekw involvement in the project’s environmental management, measures to promote employment of community members, the inclusion of cultural safety measures and financial benefits.

Chief Sipi Flamand reacted positively to the inclusion of the mine on the major projects list, calling it an announcement that is “perfectly in line with the process of economic reconciliation.”

Not everyone’s happy

Some environmental groups expressed opposition to the project being named to the list, citing concerns about the mine’s impact on water quality and the defence applications of graphite.

“This project was only at the exploratory drilling stage, and we were already observing a worrying deterioration of the waterways around its site,” Rébecca Pétrin, executive director of Eau Secours, said in a news release.

Greenpeace Canada criticized the planned use of the mine’s graphite for military purposes, writing in a news release, “critical minerals should be used to fight climate change, not wars.”
