McArthur River

Year: 2014
Client: Cameco Corporation
Project Scope Performed Under: PBN Nuna Contracting Ltd.

The McArthur River mine, in tandem with Key Lake mine, is the world’s largest producer of high-grade uranium. To prevent erosion and the deposition of materials into Boomerang Lake, a rock-lined conveyance channel was designed by the client to transfer treated mine effluent from an upstream dam location to a new precast outfall structure 420 metres downstream at Read Creek. PBN Nuna Contracting Joint Venture, a partnership with Pinehouse Business North Limited Partnership (Pinehouse First Nation), provided construction services under strict environmental monitoring.

• Peat removal
• Common fill installation
• Channel construction to strict design tolerances
• Geotextile
