Misery Site Surplus Water Atomization Project, Prototype System Design (EBA Engineering, July 2002)
1 July 2002Report
This technical design report describes a prototype surplus water atomization system for the Ekati Diamond Mine's Misery Pit development, designed to treat approximately 400,000 m³ of water annually through atmospheric dispersion and land treatment to reduce ammonia and nitrate concentrations before discharge to Cujo Lake. The system combines air stripping with tundra infiltration and biological treatment by existing microbial communities to complement traditional sedimentation pond methods and mitigate risks of exceeding water licence criteria.

Processed Kimberlite Deposition Investigation, Ekati Diamond Mine (EBA Engineering, May 2002)
1 May 2002Report
EBA Engineering assessed the physical properties of processed kimberlite deposited in Cell B of the Long Lake Containment Facility at the Ekati Diamond Mine, conducting a field program in March 2001 that recovered samples and installed instrumentation to characterize three distinct zones of varying composition and consolidation state. The investigation found excess ice in the frozen middle layer (Zone B) resulting in higher void ratios than design assumptions, while unfrozen material below (Zone C) was consolidating as anticipated.
