NexGen Broke Ground at Rook I. The Operating Licence Is Still Ahead

NexGen held a Rook I groundbreaking on August 13 in the southern Athabasca Basin. The company puts construction at $2.2 billion over four years. The CNSC already licensed site prep and construction. An operating licence is a later file.

Steel is starting. Pounds are not

NexGen Energy (TSX: NXE) held a groundbreaking at Rook I on Thursday, August 13, about 130 kilometres north of La Loche, Saskatchewan. Premier Scott Moe spoke. So did local leaders from Métis Nation-Saskatchewan and nearby Dene nations. CBC covered the day. NexGen posted the same note on its events page.

The company says it will spend $2.2 billion over a four-year build. Surface work is underway. Shaft development is aimed at 2027. The airstrip is being stretched from 914 metres to 1,780 metres. NexGen's August 4 MD&A says licenced construction started June 8, after the Canadian Nuclear Safety Commission resolved remaining licence conditions on May 22. The construction licence arrived in March. The operating licence has not.

The number they sell is 30 million pounds

NexGen estimates Rook I could produce up to 30 million pounds of U3O8 a year, about a fifth of current global supply, over a 24-year life, with 459 full-time jobs when it is running. Those are company figures at a ceremony, not a mill that has poured yellowcake. CEO Leigh Curyer tied the mine to electricity demand from AI, manufacturing, and energy security. That is the pitch. The check is whether the mill is built on budget and whether the CNSC later lets it run.

Benefit agreements sit with Clearwater River Dene Nation, Birch Narrows Dene Nation, Buffalo River Dene Nation, and Métis Nation-Saskatchewan. The dollar terms are confidential. NexGen also partnered on a 59-room hotel in La Loche.

Neutral read

NXE is on the listed utilities, power, and uranium list. A groundbreaking is not first oil and it is not first pound. Denison's Phoenix ISR project is also in the basin and is a different method. Do not staple them. Watch shaft work in 2027 and the operating-licence application. Until yellowcake leaves site, treat 20 percent of world supply as a slide.
