NWT Diamonds Project Tailings Management Plan and Preliminary Design of Retention Structures (EBA Engineering, December 1995)
This comprehensive tailings management plan prepared by EBA Engineering Consultants for BHP Diamonds describes the disposal strategy for 133 million tonnes of kimberlite tailings over 25 years of mine operation at the NWT Diamonds Project. The plan details the use of Long Lake basin for tailings storage in five sequential cells, with perimeter dams featuring permafrost cores, intermediate filter dykes, water clarification techniques, and progressive reclamation to restore the landscape to a stable, vegetated wetland environment.
