Archaeological investigations conducted for BHP Diamonds Inc. in the Lac de Gras area resulted in the discovery of 12 new archaeological sites and mitigation of 4 previously recorded sites. The work was conducted under NWT Archaeologist's permit 95-813 and included inventory and impact assessment of proposed development areas including a road to Misery Lake and associated quarries.
The Northwest Territories Water Board issued this mining exploration and development questionnaire in August 1995 to solicit supplemental information from applicants for water licence applications or renewals. The questionnaire covers geological characteristics, exploration operations, milling processes, containment areas, water treatment, environmental monitoring, and environmental assessment requirements under the Canadian Environmental Assessment Act.
Above & Beyond is a summer 1995 inflight magazine for First Air covering northern Canada and Greenland, featuring articles on Nunavut's path to territorial status, internet connectivity challenges in Arctic communities, therapeutic mud baths at Great Slave Lake, and the emerging NWT diamonds project.
A comprehensive environmental effects review of diamond mining operations prepared for Environment Canada, examining the physical, chemical, and biological impacts of diamond mining activities on aquatic, riparian, and terrestrial ecosystems across exploration, construction, operation, and reclamation phases.
A structured questionnaire commissioned by Environment Canada to collect information from diamond mining industry key contacts about environmental effects of diamond mining activities, covering exploration, mining operations, water use, waste management, tailings, open pits, and mine reclamation to support decision-making in northern Canada.
This technical chapter describes diamond mining activities worldwide, including exploration methods, ore extraction techniques (alluvial, open pit, and underground mining), mineral processing, tailings disposal, water and energy management, mine infrastructure requirements, and reclamation practices relevant to assessing environmental impacts of diamond mining operations.
An introductory chapter reviewing the global diamond mining industry, geological conditions favorable for diamond mining in Canada (particularly the Northwest Territories), and the need to evaluate potential environmental impacts of diamond mining in the Arctic due to ecosystem sensitivity and slow recovery rates.
This Environmental Impact Statement describes the proposed Ekati Diamond Mine project in the Northwest Territories, detailing the geological setting, mine development plans, operational procedures, environmental parameters including water bodies and wildlife, and community consultation with Indigenous peoples regarding the diamond mining development at Lac de Gras.
Jake Ootes presents to an Environmental Assessment Review Panel on behalf of two Yellowknife businesses (Above & Beyond Ltd and Arctic Art Gallery Ltd) in support of the BHP/Dia Met diamond mine project, arguing that the mine is essential for economic diversification, employment creation, and northern economic stability in the face of federal cost-cutting and high unemployment rates in aboriginal communities.
Canadian North presented at an Environment Assessment Review Scoping Meeting in Yellowknife on April 5, 1995, outlining the airline's history and its experience supporting northern resource extraction projects. The presentation highlighted anticipated air transportation requirements for BHP Diamonds Inc.'s proposed diamond mining project at Lac de Gras, which would require approximately 2,575 flight hours during a two-year construction period and 23,400 hours over the mine's estimated 25-year operational life.
PCL Constructors Northern Inc. presents to the Environmental Review Panel on the socio-economic benefits of BHP's proposed diamond mine at Lac De Gras, highlighting employment opportunities, long-term community growth in Yellowknife, and aboriginal training programs based on their experience with the Colomac Gold Mine Project.
Background presentation by outfitters Mike Freeland and Fred Webb to the BHP Environmental Assessment Panel regarding negative impacts of diamond exploration and mining on their established hunting and tourism operations at Lac de Gras and Courageous Lake in the Northwest Territories, including interference with caribou migration routes and loss of revenue.
"Comments on the Environmental Effects of Prospecting and Mining in Northern Canada" — a 1995 submission to the BHP Diamond Mine Panel (April 20 1995, attn. Jackie Kelly), authored by John P. Kelsall and collaborators. References Thomas, Parker, Kelsall and Loughrey (1968) barren-ground caribou population estimates, Skuncke reindeer ecology, Telfer biogeography of moose, snow goose primary age/sex indicators, and Simpson/Guyg/Kelsall (1992) study on a new freeway's effect on mule deer and moose. Topics: caribou, mining impacts, wildlife biogeography, esker mining.
Fred Webb of Coppermine HTA-Webb Ltd. and Qaivvik Ltd. submits a letter to FEARO-Vancouver detailing the negative impacts of diamond exploration and mining activities on their established tourism and caribou hunting operations at Lac de Gras, Northwest Territories, and requesting consideration and protection from the territorial and federal governments.
This Environmental Impact Statement Summary describes the NWT Diamonds Project, a joint venture between BHP Diamonds Inc. and the Blackwater Group to develop Canada's first diamond mine at Lac de Gras in the Northwest Territories. The document outlines the project description, environmental setting, community consultations, mining operations including five kimberlite pipes, tailings management, and mitigation measures addressing concerns from Aboriginal communities regarding caribou migration, water quality, grizzly bears, and traditional land use.
BHP Diamonds Inc. NWT Diamonds — Bulk Sampling Misery Lake Additional Information submission, January 17 1995, from BHP Diamonds Inc. (Yellowknife) to David Livingstone, Director Natural Resources & Environment, Department of Indian Affairs & Northern Development (DIAND, P.O. Box 1500, Yellowknife). Covers the exploration access road from west of Paul Lake to Misery Lake (following natural drainage divides, 10 km connecting road to other exploration targets), spring-freshet peak-flow accommodation at the Paul Lake stream crossing, Fish Habitat Assessment using back-pack electroshocker (1994 spring/summer survey — adult fish dominance spring with spawning grayling), and EBA Engineering particle-size analyses of soils (clay/silt/sand/gravel grading).
BHP Diamonds Inc.'s project description report for the proposed NWT Diamonds project outlines plans to develop Canada's first diamond mine in the Lac de Gras area, approximately 300 km northeast of Yellowknife. The report details the mining of five kimberlite pipes (Panda, Misery, Koala, Fox, and Leslie) through open pit and underground mining methods, with processing operations, infrastructure, environmental baseline conditions, and anticipated impacts on aquatic, terrestrial, and socioeconomic environments.
BHP Diamonds Inc. submitted a Project Description Report for the proposed NWT Diamonds project, Canada's first diamond mine located 300 km northeast of Yellowknife, describing plans to develop five kimberlite pipes through open pit and underground mining with production from mid-1995 to mid-2021, processing 9,000-18,000 tonnes per day of ore, and addressing environmental and socioeconomic impacts including aquatic habitat loss, wildlife disturbance, and employment generation.
BHP Diamonds Inc. submits comments on draft EIS guidelines for the BHP Diamond Mine project, addressing the definition of proponent, incorporation of traditional knowledge, land claims considerations, and cumulative effects analysis including power generation requirements.
BHP Minerals Canada Ltd. submitted a comprehensive project description report for the proposed NWT Diamonds Project, a large-scale diamond mining operation located 300 km northeast of Yellowknife in the Coppermine River basin.
