Rio Tinto has decided to slow construction at the Nemaska Lithium project in Quebec, Canada. The move follows a detailed internal review after the company took direct control of the project.
The decision is aimed at improving project planning and long-term performance. While progress will continue, the pace of construction will remain lower during the optimisation phase.
Topic Snapshot
- Construction pace reduced at Nemaska lithium project
- Project is located in Quebec, Canada
- Facility is over 70% complete
- Slowdown allows project optimisation work
- Workforce at site will temporarily decline
- Over $300 million investment planned for 2026
Why Rio Tinto Slowed Construction?
The slowdown comes after Rio Tinto reviewed the project’s progress and execution plan. The company found that adjustments were needed to improve efficiency and long-term outcomes.
By reducing construction speed, the company can focus on refining the project design and execution strategy.
Current Status of the Project
The Bécancour lithium hydroxide facility is already well advanced. Key highlights include:
- Engineering work fully completed
- Construction more than 70% finished
This means the project is still moving forward, even with reduced activity on site.
What Happens During the Optimisation Phase?
During this phase, some construction work will continue, while other parts will be paused or delayed.
Key actions include:
- Reviewing project execution plans
- Improving cost and schedule control
- Adjusting construction sequencing
Contractor numbers at the site will also decrease for a limited time.
Maintaining Long-Term Commitment
Rio Tinto confirmed that the slowdown does not change its long-term plans. The company remains committed to:
- The Nemaska Lithium project
- Building a strong presence in Quebec’s lithium sector
It plans to invest more than $300 million in its Quebec lithium operations in 2026.
Leadership and Coordination Improvements
The company is also updating its project leadership structure. This step aims to improve:
- Oversight and governance
- Coordination between project teams
- Overall decision-making efficiency
Better alignment between Rio Tinto and Nemaska Lithium teams is expected to support smoother execution.
Next Steps for Construction
Construction will continue at a slower pace until optimisation work is complete. After that, activity is expected to increase again.
At this stage, the company does not expect major changes to the overall project timeline.
Closing
The Nemaska lithium project slowdown reflects a strategic decision by Rio Tinto to strengthen execution rather than rush development. With strong investment plans and continued work on site, the project remains a key part of the company’s lithium growth strategy.
