Rook I Project

NexGen Energy Ltd. (NexGen) is proposing to develop an underground uranium mine on the Patterson Lake peninsula in the southwestern Athabasca Basin in northern Saskatchewan, approximately 155 km north of the town of LaLoche, SK. The proposed Rook l mine would produce up to 14 million kg of U3O8 annually for twenty-four years.

Under the Nuclear Safety and Control Act, NexGen's proposal requires approval and licensing by the Canadian Nuclear Safety Commission (CNSC). An environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required, and an EA decision affirming that the proposed activities will not cause significant adverse environmental effects, before the CNSC can make a licensing decision on this proposal.

This project is also subject to the environmental assessment requirements of the Government of Saskatchewan.

Latest update

August 28, 2019 - Canada’s new Impact Assessment Act (IAA) came into force. Under the transitional provision set out at section 182 of the IAA, given that the proposed Rook I Project commenced under the Canadian Environmental Assessment Act, 2012 and a decision statement has not yet been issued, the project will continue under the process set out in the CEAA, 2012. The letter sent to NexGen Energy Ltd. regarding the changes to federal legislation can be found here.
