This report documents the results of the 2002 spring waste rock storage area seepage survey at Ekati Diamond Mine, conducted in June 2002 in accordance with Water Licence N7L2-1616 requirements. The survey monitored seepage quality from multiple waste rock and kimberlite storage areas, including chemical analysis of water samples for pH, conductivity, major ions, nutrients, and metals.
MEND Manual Volume 3 on Prediction is a comprehensive reference document for Canadian mining industry practitioners on sampling, analysis, prediction, prevention, control, treatment and monitoring of acidic drainage from mines. The manual provides information on chemistry, engineering, economics, case studies and scientific data for mine operators, environmental staff, consulting engineers and governments.
BHP Billiton Diamonds Inc. submits habitat unit calculations for Leslie Lake to the Department of Fisheries and Oceans in support of a Fisheries Authorization Application for the Sable, Pigeon, and Beartooth Kimberlite Pipes. The document provides baseline fisheries data, habitat zone mapping, and weighted habitat unit calculations for three target fish species (Arctic grayling, lake trout, and round whitefish) based on 1994 survey data.
This draft scope of work outlines the re-evaluation and refinement of the Aquatic Effects Monitoring Program (AEMP) and Panda Diversion Channel Monitoring Program (PDCMP) at Ekati Diamond Mine, detailing specific issues to be evaluated (sampling locations, frequencies, parameters, QA/QC procedures) and proposed analytical methodologies to improve monitoring programs for 2003-2007 field seasons.
The Northwest Territories Department of Resources, Wildlife and Economic Development expresses support for Environmental Monitoring Advisory Board recommendations on caribou and wildlife monitoring activities at the Diavik Diamond Mines Project and commits to immediate action through designated departmental representatives.
East Desperation Pond Cofferdam As-Built Construction Report for the Ekati Diamond Mine (BHP Billiton Diamonds Inc., Project No. 0101-94-11580.058), July 2002, prepared by EBA Engineering Consultants Ltd. Includes the As-Built Construction Drawings package (Drawing Index: 11580.058-DPAB01 General Location and Misery Site Plan), UTM Coordinates (NAD 83), East Cofferdam construction sequence (GCL Liner placement at elevations 5.10 / 2.95 / 2.15 / 0.75 m), and loading-ramp configuration for front-end-loader external-feed hopper with Grizzly conveyor.
Geotechnical site investigation report for the proposed Bearclaw Diversion Dam at the Ekati Diamond Mine, documenting subsurface conditions from eight boreholes drilled in April 2002 to support the development of the Beartooth kimberlite pipe. The investigation characterized till overburden (0.3–5.8 m thick) overlying granite bedrock, ground temperature regimes indicating warm permafrost, and bedrock joint characteristics for dam design.
This as-built construction report documents the monitoring and completion of the Waste Rock Dam and Seepage Collection Dam at the Ekati Diamond Mine's Misery site from November 2001 to May 2002, detailing foundation preparation, material placement, liner system installation, thermosyphon construction, and quality assurance testing.
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.
Monthly water surveillance report for May 2002 submitted by BHP Diamonds Inc. to the Mackenzie Valley Land and Water Board, documenting water sampling results from four stations, flow/volume measurements from multiple mine lakes and ponds, waste rock disposal quantities, and associated weather data in compliance with water licence N7L2-1616.
This addendum to the approved Waste Rock and Ore Storage Management Plan (February 2000) presents updated geological, geochemical, and characterization data for the Fox Pipe at Ekati Diamond Mine, along with refinements to waste rock management strategies based on site experience and adaptive management practices since 2000. The plan describes geochemical testing results, monitoring methods, and waste rock storage management strategies incorporating permafrost formation, encapsulation of reactive kimberlite, and toe berm construction to control runoff.
A compilation index of environmental assessment documents and correspondence related to diamond mining projects (DeBeers Snap Lake, Diavik) and other mining developments in northern Canada, including regulatory framework documents, technical reports, and consultation records spanning 1996–2002.
This conference paper describes BHP Billiton's Ekati Diamond Mine in the Northwest Territories and its contribution to sustainable development through integrated environmental, economic, and social management. The document outlines the Environmental Agreement, Socio-economic Agreement, and Impact Benefits Agreements established with governments and Aboriginal groups, as well as environmental management practices and monitoring programs.
A comprehensive catalog of MEND (Mine Environment Neutral Drainage) program reports and resources available for purchase, covering research, prevention, control, and treatment methods for acid mine drainage from mining operations, with ordering information for the MEND Secretariat.
The IEMA proposes that EMAB and the Agency jointly host a workshop with Aboriginal groups to develop guidelines for how mining companies should incorporate and respect traditional knowledge in monitoring and management of northern mines, recognizing the mandate of both organizations to promote integration of traditional knowledge into environmental programs.
Ted Blondin notifies IEMA that the West Kitikmeot/Slave Study Society is postponing the May 23-24, 2002 Partnership Workshop for the Interim Research Agenda to integrate it with broader Regional Monitoring Agency discussions planned for late October.
Ted Blondin of the West Kitikmeot/Slave Study Society invites Zabey Nevitt of IEMA to attend a Partnership Workshop on May 23-24, 2002 in Yellowknife to develop an Interim Cumulative Effects Research and Monitoring Plan for the Slave Geological Province area, with results of independent evaluation and synthesis of prior research recommendations.
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.
A training handout by DIAND outlining seven steps to perform risk assessments for mining operations, focusing on system boundaries definition, hazard identification, failure mode evaluation, likelihood and consequence assessment, and risk determination using both qualitative and quantitative methodologies.
This DIAND technical short course handout from Mehling Environmental Management Inc. presents comprehensive theory and prediction techniques for acid rock drainage (ARD), covering ARD generation mechanisms, prediction methodologies (static and kinetic testing), field monitoring approaches, and mitigation strategies for mining and construction projects.
