With these regulatory steps complete, NexGen is set to begin full construction of the project.
Rook I is situated in the Athabasca Basin in Saskatchewan and has been developed in collaboration with local indigenous communities.
Once operational, it is expected to contribute significantly to the global uranium fuel supply.
The project aims to produce up to 30 million pounds (mlb) of uranium annually, which would account for more than 20% of the current global supply and more than half of the Western world’s output.
