Proposed Development of Sable, Pigeon and Beartooth Kimberlite Pipes, Ekati Diamond Mine, Land Use Permit and Water Licence Supporting Document (BHP Billiton, August 2001)
BHP Diamonds Inc. submitted this supporting document to the Mackenzie Valley Land and Water Board for regulatory permits to develop three additional kimberlite pipes (Sable, Pigeon, and Beartooth) at the Ekati Diamond Mine in the Northwest Territories. The document describes the proposed open pit mining methods, waste rock and water management strategies, infrastructure requirements, and abandonment/restoration plans for each pipe, building upon the existing regulatory framework and environmental agreements already in place for the mine.
