Nemaska Lithium Inc. is a Quebec-based Canadian company engaged in lithium mining and the production of battery-grade chemicals. It develops an integrated project that extracts spodumene from the Whabouchi mine in the Eeyou Istchee James Bay region of northern Quebec and converts it into high-purity lithium hydroxide at a facility in Bécancour, Quebec. The company previously operated a demonstration hydrometallurgical plant in Shawinigan, Quebec.
Its primary products are lithium hydroxide and lithium carbonate used in lithium-ion batteries for electric vehicles, energy storage, and consumer electronics. The project emphasizes sustainability, powered by renewable hydroelectric energy, aiming for one of the lowest carbon footprints in the industry and full supply chain traceability.
As of February 2026, Rio Tinto plc holds a 53.9% majority stake and has assumed direct management responsibilities, while Investissement Québec holds the remaining 46.1%. This structure supports the development of Quebec's battery supply chain. Nemaska Lithium positions itself as a key contributor to North America's critical minerals sector, with first production at the Bécancour plant targeted for 2028.
