Mine Decomissioning

Denison Environmental Services (DES) began with a vision to provide contracting capabilities that could accommodate any closure project, from asset removal to complete mine decommissioning (including demolition and major earthworks) and continue on to perform the long-term maintenance and environmental monitoring.

  • • Gunnar Closed Uranium Mine – Select Demolition
  • • Cluff Uranium Mine – Mill Demolition
  • • Bicroft Closed Uranium Mine – Site Remediation
  • • Denison & Stanrock – Complete Decommissioning and Rehabilitation of Mine, Mill and Tailing Areas
  • • Algoma Ore Division – Mine and Sinter Plant Demolition and Rehabilitation
  • • Aunor – Mine Demolition and Rehabilitation
  • • Aquarius - Mine Demolition and Rehabilitation
  • • Shebandowan - Mine Demolition and Rehabilitation

Once the physical hazards and geotechnical stability is established, DES has the ability to provide specialized environmental monitoring and reporting. See Mine Care and Maintenance for more information on the services DES provides to manage the next phase of closure.
