Rio Tinto announced on Wednesday that it had acquired a majority stake in Canada's Nemaska Lithium. This is a step forward for its plan to create an integrated lithium business in Quebec.

Anglo-Australian mining company now holds 53.9% of the stake and will take over direct management of the lithium producer, while Quebec government owns 46.1%.

Rio Tinto wants to create a "fully integrated" lithium supply chain, starting with the mining of raw ore and ending with chemical processing in Quebec to serve the North American market for electric vehicles.

Rio Tinto, the eastern Canadian province and its economic development agency Investissement Quebec have invested in Nemaska 'Lithium' since March - 2025.

It was added that the partners would continue to fund this project, which includes the lithium hydroxide facility in Becancour. The first production is expected in 2028.

The company announced that Quebec would invest an additional $200 millions?in Nemaska Lithium via share subscriptions. This is on top of the $300 million investment made by Rio Tinto to develop the lithium sector in Quebec in 2026.

Through its acquisition of?Arcadium, in March 2025 Rio?Tinto acquired a half interest in Nemaska Lithium. This includes the lithium?hydroxide?plant in Becancour?Quebec and the Whabouchi spodumene?mine located in the Eeyou Istchee region of James Bay, Quebec.
