Wheeler River Project

Denison Mines Corp. (Denison) is proposing to develop an in situ recovery uranium mining and processing operation located in the Athabasca Basin in northern Saskatchewan, approximately 600 km north of the city of Saskatoon, 4 km west of Highway 914 and midway between Cameco Corporation's Key Lake Mill and McArthur River Mine. The proposed Wheeler River mine would produce up to 5400 tonnes of U3O8 annually for twenty years.

Under the Nuclear Safety and Control Act, Denison's proposal requires approval 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.
