Rook I Project
The Rook I Project is a world-class uranium development in northern Saskatchewan centred on the high-grade Arrow Deposit, one of the largest uranium discoveries globally. Fully licensed for construction and currently under development, the project is expected to become one of the world’s largest and lowest-cost uranium mines, producing approximately 30 million pounds of U₃O₈ annually and supplying a significant share of global uranium demand.

How BuildAtlas reads this record
Rook I adds a second substantial uranium development to the nuclear-fuel chain, allowing the cluster view to show a recurring capability demand rather than a single-project story.
What to keep in view
- Requires: uranium production, mining and processing, nuclear fuel supply, remote logistics.
- Dependencies: northern logistics, provincial grid.
- Open constraints: construction execution, regulatory and indigenous readiness.
What this page does not establish
A source-described stage, capital figure, or proposed capability is not the same as completed construction, committed financing, operating output, or guaranteed delivery. BuildAtlas keeps those distinctions visible.
