NextSource Materials Inc. plans to build a graphite-purification plant in Mauritius’ freeport zone, supplying manufacturers with the substance used to make electric-vehicle batteries.
The facility will have capacity to produce 3,600 tons annually, expanding to 14,400 tons after 2024, the local unit of the Toronto-based company said in filings with the government. The graphite will come from the company’s mine in Madagascar and be processed into exportable battery-grade graphite at Mer Rouge in Mauritius’s freeport zone, it said.
