Rio Tinto (RIO) announced Wednesday that it's now the majority owner of Nemaska Lithium, holding a 53.9% stake in the Quebec-based lithium producer. More importantly, the mining giant is stepping in to run the show directly, signaling its serious commitment to building an integrated lithium business in the region.
The ownership shift comes after equity investments from both Rio Tinto and the Government of Quebec, which is staying involved as a partner. This isn't just a financial play—Rio Tinto plans to bring its operational expertise to the table, managing development, operations, and sales to create a fully integrated lithium operation.
Following the Money: Who's Funding What
The partnership with Quebec's government remains strong, with funding flowing toward the lithium hydroxide plant in Bécancour. That facility is already 60% complete, which means the heavy lifting is well underway. The financial commitments are substantial: Quebec will put up to $200 million into Nemaska Lithium, while Rio Tinto is committing over $300 million in 2026 alone.
These aren't small numbers, and they reflect just how strategically important this project is for Rio Tinto's lithium ambitions. The company is clearly betting that control and direct management will accelerate the project's completion and improve its long-term performance.
Building Quebec Into a Lithium Hub
Jérôme Pécresse, Chief Executive of Rio Tinto Aluminium & Lithium, emphasized that the Quebec operations are central to the company's lithium strategy. He noted that Nemaska Lithium's evolution is pivotal for meeting Rio Tinto's growth and performance objectives in the lithium sector.
The broader strategy here is about positioning Rio Tinto to supply materials for future industries. Lithium demand continues to grow as electric vehicles and battery storage expand, and securing a strong position now could pay off significantly down the road. With engineering complete at the Bécancour site, the focus shifts to finishing construction and getting the plant operational.
This development should substantially boost Rio Tinto's ability to meet rising demand for lithium products and strengthen its integrated offerings in the market.
