NexGen Energy (ASX:NXG) has achieved a historic milestone, receiving final federal approval from the Canadian Nuclear Safety Commission for its 100%-owned Rook I Uranium Project.
The CNSC issued the licence to prepare site and construct following the approval of the project’s environmental assessment.
The regulatory green light marks the conclusion of a rigorous 12-year review process and serves as the final authorisation required to initiate full-scale construction in Saskatchewan’s Athabasca Basin.
Located in a premier mining district, the Rook I Project is designed to be the largest and most environmentally advanced uranium mine globally.
At full capacity, it is projected to produce up to 30 million pounds of uranium annually.
The output represents a shift in the energy landscape, accounting for over 20% of the current global uranium fuel supply and more than 50% of the supply for the Western world.
With a final investment decision already confirmed, NexGen is scheduled to commence official construction in the northern summer of 2026.
The company has already mobilised teams for procurement, engineering, and shaft sinking preparation.
The construction phase is expected to span four years, generating substantial economic benefits and skilled employment for local Indigenous communities and the broader region.
CEO Leigh Curyer highlighted the achievement as a testament to a "culture of excellence," positioning Canada as a critical energy superpower capable of meeting the accelerating global demand for clean, baseload nuclear energy.
