Bécancour, Québec – Rio Tinto Group has solidified its position in the burgeoning North American lithium market, taking majority control of Montreal-based Nemaska Lithium. The move, announced Wednesday, underscores the growing global demand for critical minerals essential to the production of electric vehicles and stationary energy storage, and represents a significant investment in Québec’s resource sector. This development in Nemaska Lithium, a fully integrated spodumene-to-lithium hydroxide development project, signals a strategic push by the mining giant to establish a robust lithium supply chain.
Following a series of equity investments from both Rio Tinto and the government of Québec over the past year, Rio Tinto now holds a 53.9% stake in Nemaska Lithium, assuming direct management responsibilities. The government of Québec retains the remaining ownership. The Anglo-Australian firm will leverage its extensive experience in development, operations, sales, and marketing to build what it hopes will be a leading integrated lithium business within the province. This isn’t simply a financial transaction; it’s a transfer of operational control, with Rio Tinto now at the helm of Nemaska’s ambitious project.

Québec’s Investment and Future Funding
The province of Québec has been a key partner in the Nemaska Lithium project, committing a total of $1.1 billion CAD since 2020. Québec Economy Minister Jean Boulet stated that this latest investment will be the “final” contribution from the provincial government, signaling confidence in Rio Tinto’s ability to bring the project to fruition. Both partners have pledged significant funding for the current year: Québec will invest up to US$200 million, while Rio Tinto is committing more than US$300 million, according to publicly available information. This financial commitment is crucial for advancing the project’s development and ensuring its long-term viability.
Rio Tinto’s Expanding Lithium Portfolio
Rio Tinto’s move into Nemaska Lithium builds upon its recent expansion in the lithium market. Last year, the company completed the $6.7 billion acquisition of Arcadium Lithium PLC, a company with operations spanning Argentina, Australia, China, and Japan. Arcadium’s existing assets included the Quebec-based holdings now under Rio Tinto’s control. Prior to these acquisitions, Rio Tinto’s presence in the lithium sector was limited. The company also owns the Galaxy project, which mines spodumene, a lithium-bearing hard rock, further diversifying its lithium resources.
The company is currently evaluating whether to prioritize spodumene supply from its Galaxy project or Nemaska Lithium’s Whabouchi mine for processing at the Bécancour facility. The Whabouchi mine, located in the Eeyou Istchee James Bay region of Québec, is a key component of Nemaska Lithium’s integrated operations. The Bécancour plant is designed to convert spodumene concentrate into lithium hydroxide, a critical material used in the production of batteries for electric vehicles and energy storage systems.
Navigating Market Uncertainty and Project Adjustments
Despite its bullish outlook on lithium demand, Rio Tinto has recently demonstrated a more cautious approach to project development. The company mothballed its $2.3 billion Jadar lithium project in Serbia last month, citing uncertainty surrounding supply conditions. This decision reflects a broader trend within the industry, as companies grapple with fluctuating market dynamics and potential supply chain disruptions. Rio Tinto anticipates commencing production at the Bécancour facility in 2028, a timeline that allows for careful assessment of market conditions and optimization of its lithium supply strategy.
Québec’s Role in the Critical Minerals Supply Chain
Rio Tinto’s significant presence in Québec extends beyond lithium. The Saguenay-Lac-Saint-Jean region is home to nearly half of the company’s global aluminum production, highlighting the province’s importance as a key mining hub. The Nemaska Lithium project is expected to further strengthen Québec’s position in the critical minerals supply chain, contributing to the province’s economic growth and supporting the transition to a low-carbon economy. The project is expected to create jobs and stimulate economic activity in the region, benefiting local communities and bolstering Québec’s industrial base.
The investment in Nemaska Lithium comes as governments worldwide are increasingly focused on securing reliable supplies of critical minerals. These minerals are essential for a range of technologies, including electric vehicles, renewable energy systems, and defense applications. The competition for these resources is intensifying, and countries are seeking to diversify their supply chains and reduce their dependence on single sources. Rio Tinto’s commitment to Nemaska Lithium positions Québec as a key player in this global effort to secure a sustainable and resilient supply of critical minerals.
Rio Tinto will now focus on optimizing the integration of Nemaska Lithium into its broader portfolio, streamlining operations, and ensuring the successful completion of the Bécancour processing facility. The company is expected to provide further updates on its lithium strategy and project timelines in the coming months. The next key milestone will be the completion of a detailed feasibility study for the integrated lithium complex, which is expected to provide a more precise timeline for production and investment.
