Prime Minister Mark Carney said construction is beginning on what he says will be the largest graphite mine in the G7.
The Nouveau Monde Graphite’s Matawinie Mine in Québec will supply up to 106,000 tonnes of graphite annually over 25 years, which Carney told reporters on May 19 is “eight times Canada’s total graphite production right now.” He said the mine would attract $2 billion of investment to Canada.
