With its 53.9-per-cent stake, Rio Tinto has assumed direct management of the Bécancour, Que.-based lithium mining company, which operates Whabouchi mine, which sits on the world’s second-largest reserve of the mineral. The British-Australian multinational mining company will invest more than US$300 million in Nemaska this year.

Talking point: Founded in 2007, Nemaska has struggled over the years, underscoring the difficulty of turning a profit when mining the mineral crucial to the manufacturing of EV batteries. Rio Tinto acquired a 50-per-cent stake in Nemaska in March 2025. Nemaska’s assets include a lithium hydroxide plant in Bécancour.
