281:"the Claude pit was completely filled in. The DJ/DJX and D pits were flooded and remain isolated from adjacent natural water bodies. Potentially problematic portions of the surface waste rock piles were placed into the pits, while the remainder of the surface waste rock was contoured, covered and revegetated. The portals and vents to the underground mines were closed and the TMA was contoured, covered and revegetated. All structures were dismantled and disposed of."

289:"The licence renewal also reduced the licensed area for sections that were not used for mining and milling from the licence footprint to allow Orano to return the surface leases to the Province of Saskatchewan. There were no issues or concerns identified. The recovery of the site is proceeding as anticipated"

Mining infrastructure consisted of a central mill, above ground tailings management area, 3 open pits, 2 underground mines, associated waste rock piles, and site infrastructure including the Cluff Lake airstrip and residences.
