Major mine project aims to bolster Saskatchewan’s uranium role
Construction has begun on NexGen Energy’s Rook I Project in the southwestern Athabasca Basin, marking a large-scale investment in Saskatchewan’s uranium industry and drawing federal and provincial officials to the groundbreaking.
The company says the development, built around the high-grade Arrow Deposit, carries a price tag of roughly $2.2 billion and is expected to produce up to 14 million kilograms of triuranium octoxide annually once in operation — a concentrated form of uranium oxide commonly called “yellowcake.”
“Nuclear energy has become key to meeting that demand and with it uranium has become one of the world’s most strategic resources.” — Premier Scott Moe
The ceremonial event brought together a cross-section of political and business figures, including former prime minister Stephen Harper, federal Secretary of State for Rural Development Buckley Belanger, investor Kevin O’Leary and provincial leadership. NexGen has said the project could support roughly 1,400 jobs annually in Saskatchewan.
Located about 155 kilometres north of La Loche and roughly 150 kilometres south of Fond-du-Lac, Rook I sits on Treaty 8 territory in a region already known for some of the world’s highest-grade uranium deposits.
Indigenous agreements and local infrastructure
NexGen says it has signed benefit agreements with several Indigenous communities: Buffalo River Dene Nation, Birch Narrows Dene Nation and Clearwater River Dene Nation, as well as the Mètis Nation—Saskatchewan. The company has also partnered with the Mètis Nation—Saskatchewan and Clearwater River Dene Nation to help build a 59-bed hotel in La Loche, intended to support workers and visitors during construction and operations.
Company and government representatives emphasised that the project represents an economic opportunity for northern and Indigenous communities, promising jobs and local contracts during the multi-year construction and subsequent operations.
Timeline, approvals and next steps
On March 5, the Canadian Nuclear Safety Commission approved NexGen’s environmental assessment and issued a licence to prepare the site and construct the Rook I Project. NexGen has indicated construction will take roughly four years.
| Item | Detail |
|---|---|
| Estimated capital cost | $2.2 billion |
| Expected annual production | Up to 14 million kg triuranium octoxide |
| Estimated jobs supported | ~1,400 annually |
| Construction timeline | Approximately four years |
Those numbers place Rook I among the more significant resource projects in the province, both for scale and for the global market it serves. As countries look to expand low-carbon power sources, demand for uranium that fuels nuclear reactors has increased, an economic driver NexGen and provincial officials referred to at the groundbreaking.
Local reactions and lingering questions
Leaders from the surrounding area attended the event; local officials have framed the project as an opportunity for northern communities hard hit by fewer economic options. At the same time, major mine developments often raise concerns about environmental monitoring, long-term reclamation and the distribution of economic benefits.
Community-level agreements and the hotel project signal efforts to capture local economic spin-off, but details about contractor hiring, training programs, and how benefits will be phased over construction and operations were not disclosed in the event materials.
- Economic promise: job creation, contracts and infrastructure spending for northern Saskatchewan.
- Partnerships: signed benefit agreements with several Indigenous nations and commitments to local infrastructure.
- Regulatory green light: CNSC approval granted for site preparation and construction.
Construction at Rook I will be watched closely by communities in the Athabasca Basin and by provincial officials juggling the economic benefits of resource development with environmental oversight responsibilities.
For residents in La Loche and nearby communities, the next months will be when the project shifts from planning and approvals to heavy activity as roads, camps and initial site works begin to take shape. NexGen’s further announcements on local hiring, procurement and environmental monitoring will determine how the promises on stage translate into outcomes on the ground.
This development reinforces Saskatchewan’s standing in the global uranium market and adds another sizable project to the province’s resource-led economy, while highlighting the continuing need for transparent engagement with northern and Indigenous communities who host major industrial projects.
