Key Lake Mine
Client: Cameco Corporation
The Key Lake Mine is a former uranium mine in Saskatchewan and is the site of the largest uranium mill in the world. It is located 570 km north of Saskatoon by air on the southern rim of the uranium-rich Athabasca Basin. PBN Nuna Contracting Ltd. (PBN Nuna), commenced work at the Key Lake site in May 2012. PBN Nuna’s scope included: excavation and relocation of approximately 2.4 million m3 of sand; 283,500 m3 of waste rock screening and placement for the stabilization of the embankment of the Deilmann Tailings Management Facility (a tailings pond); numerous road upgrades and realignments including the decommissioning and installation of several road crossings (culverts); and haul road ditching and check dam construction. The Project required mobilization of approximately 30 pieces of heavy equipment along with support equipment, buildings, and other facilities to support the PBN Nuna workforce. PBN Nuna demobilized October 2013.
