This technical overview working document outlines the Aquatic Effects Monitoring Program (AEMP) for the BHP Diamonds Project (Ekati Diamond Mine), detailing the framework for monitoring aquatic environments during all project phases. The program employs a tiered approach combining water quality measurements, sediment analysis, and biological community assessment across reference and potentially impacted lakes and streams to detect project-related impacts and test environmental predictions from the EIA.
This final geochemical characterization report for BHP Diamonds' proposed diamond mine in the Northwest Territories evaluates the acid/alkaline rock drainage potential of waste rock, ore (kimberlite), and tailings through static and kinetic testing methods. The study predicts water quality from mine facilities including waste rock dumps, pits, underground workings, ore stockpiles, and tailings, identifying the Misery Schist Waste Rock Dump as a potential source of acidic drainage with elevated metal concentrations, while most other facilities are expected to remain benign.
This is the 1997 Environmental Agreement Annual Report for the Ekati Diamond Mine, Canada's first diamond mine located in the Northwest Territories barrenlands, providing a comprehensive plain-English summary of environmental monitoring programs across water quality, aquatic life, wildlife, vegetation, and cultural heritage throughout the first year of mine construction and operations.
This report presents the results of the 1997 Kodiak Lake Sewage Effects Study, a three-year monitoring program initiated to examine the effects of treated sewage effluent from the Ekati Mine camp (500–1000 people) on the aquatic environment of Kodiak Lake. The study documents changes in water quality, sediment quality, primary and secondary producers, and fish populations resulting from sewage discharge that began in April 1997, with comparisons to pre-discharge baseline data from 1993–1996.
Proposal for a comprehensive kimberlite toxicity study for BHP Diamonds Inc. under Water Licence N7L2-1616, designed to assess acute and chronic effects of kimberlite solutions from diamond processing on aquatic organisms and fish health through laboratory bioassays, toxicity identification evaluations, and sub-lethal exposure experiments.
BHP Minerals Canada Ltd. submitted a Fish Habitat Compensation Program plan for the Panda Lake Diversion Channel, developed by Dillon Consulting Limited to address harmful alteration of fish habitat from mining operations. The plan details fish habitat creation, enhancement, monitoring and maintenance designs for a 3,400-meter diversion channel constructed between Panda and Kodiak Lakes to restore fish connectivity and compensate for 930 meters of impacted stream habitat in the Koala Watershed.
This is a fish habitat compensation plan for the Panda Lake Diversion Channel developed by BHP Minerals Canada Ltd. and Dillon Consulting to address impacts of the NWT Diamonds Project on stream fish habitat. The plan details physical and hydrological characteristics of the constructed diversion channel, proposed habitat creation and enhancement features, monitoring protocols, and a phased implementation strategy to achieve no net loss of fish habitat as required by the federal Fisheries Act.
This 1997 baseline fisheries resource and habitat survey of Beartooth Lake documents fish species composition, population estimates, condition factors, and habitat characteristics prior to planned bulk sampling diamond drilling. The survey found Arctic grayling and lake trout as primary species, with population estimates of 98–131 Arctic grayling and 42–46 lake trout susceptible to index gill nets, alongside oligotrophic water conditions and limited stream spawning habitat.
BHP Diamonds Inc. requests modification to water licence N7L2-1616 to repair and reline the Phase 1 tailings containment area due to liner damage discovered during inspection. The remediation work includes dewatering the unlined portion, removing the pumphouse, installing a new HDPE liner, and infilling with till material and waste rock.
BHP Diamonds Inc. submitted an Interim Abandonment and Restoration Plan for the NWT Diamonds Project on September 30, 1997, detailing comprehensive reclamation strategies for five kimberlite pipes (Panda, Koala, Fox, Leslie, and Misery) over a projected 25-year mine life, including methods for stabilizing open pits, managing tailings, storing waste rock, and restoring vegetation and water resources.

This report documents a sediment survey of Kodiak Lake conducted in August 1997 to assess sediment loading from the Panda Diversion Channel, which was constructed to maintain water connection between Panda and Kodiak lakes during mining operations at the NWT Diamonds Project. Results show that channel sediments were primarily confined to the delta at the channel mouth and shallow areas within approximately 200–600 meters of the discharge point, with thicknesses ranging from 2 to over 30 centimeters.
