BHP Diamonds Inc. 1999 Waste Rock Area Seepage Survey "Book #10" — transmittal November 17 1999 to Gordon Wray, Chairman, NWT Water Board. Same survey as "#13 1999" with additional appendix material: Appendix A Test Methodologies (ETL EnviroTest sub-contracted labs in Edmonton, Calgary, Saskatoon, Thunder Bay, Winnipeg, Grande Prairie; analytical methods for Beryllium, Boron, Cadmium, Calcium, Chromium, Cobalt, Copper, Iron, Sulphate by Ion Chromatography), and weekly leachate test results from February-October 1995 (pH, acidity/alkalinity as CaCO3, conductivity, sulphate SO4) on the Panda waste rock pile draining to Beartooth Lake, with pH-below-6.0 trigger threshold for seepage controls.
This final report documents a satellite telemetry study of barren-ground grizzly bears in the Slave Geological Province (1995-1999), identifying three populations (North Slave, Bathurst Inlet, Kugluktuk), characterizing habitat selection patterns, home range sizes, seasonal movements, and denning ecology to inform mining development management decisions.
BHP Diamonds Inc. 1999 Waste Rock Area Seepage Survey transmittal letter (November 17 1999) and report to Gordon Wray, Chairman, NWT Water Board (Yellowknife). File reference 1616. Discusses the Panda waste rock pile drainage into Beartooth Lake, pH-6.0 trigger threshold for initiating seepage controls, and includes ETL EnviroTest (Edmonton/Calgary) Chain of Custody analytical reports with chemistry results for seepage samples.
Petrographic and scanning electron microscopy analysis of tailings and backfill samples from a mining operation, documenting mineral composition, texture, sulfide assemblages, and grain size distributions.
The Arctic Energy Alliance's first newsletter (November 1999) presents the organization's mission to reduce energy costs and environmental impact in the NWT through energy efficiency and renewable energy adoption. The issue covers Y2K preparedness for power infrastructure, energy management strategies, global climate change and NWT emissions reduction initiatives, and features projects like natural gas conversion in Inuvik and community energy assessments.
Huckleberry Mines Ltd. presents operational material characterization and weathering monitoring procedures for their porphyry copper deposit, including ARD assessment of waste rock types, daily digging plans based on NPR and copper grade classification, and integrated water quality and materials handling monitoring protocols.
The Mackenzie Valley Environmental Impact Review Board distributes a regular update on activities related to the BHP Ekati Diamond Mines expansion and Ranger Oil pipeline development, documenting community consultations and environmental assessment progress for the proposed Pigeon, Beartooth, and Sable Kimberlite Pipes.
Draft best practices and reporting guidelines for mineral exploration and mining companies in Canada, developed by a committee of industry associations to establish standards for technical reporting and exploration program design by Qualified Persons. The document provides detailed procedures for geological work, sampling, drilling, analysis, and resource estimation to maintain public confidence and assist securities regulators.
2001 Rock Storage Area Seepage and Waste Rock Survey Report binder for the Ekati Diamond Mine (BHP Billiton). Includes correspondence with the Mackenzie Valley Land and Water Board (MVLWB — Laurie Cordell, Melody MacLeod), BHPB responses (Jim Millard, David Scott, Brent Murphy), 2001 Aquatic Effects Monitoring Program refinements, Panda and Misery seepage monitoring station maps and locations (SEEP-001 through SEEP-083 — Cujo Lake, Thinner Lake, King Pond Dam, Beartooth Lake, Bearclaw Lake, Beartooth waste rock storage area, Coarse Kimberlite Storage Area), and recommendations for granite vs. kimberlite seepage monitoring frequency.
BHP Diamonds Inc. proposes to develop three additional kimberlite pipes (Sable, Pigeon, and Beartooth) at the Ekati Diamond Mine in the Northwest Territories to extend mine life from 15 to 18 years. The project description outlines mining methods, waste and water management strategies, infrastructure requirements, and environmental mitigation measures for the three new open pit operations, prepared in response to Mackenzie Valley Environmental Impact Review Board requirements and incorporating community consultation feedback.
The Mackenzie Valley Environmental Impact Review Board distributes a regular update on environmental review activities for the BHP Ekati diamond mine expansion and the Ranger Oil/Canadian Forest Oil/Chevron natural gas development, outlining required consultations, development descriptions, and next steps in the environmental assessment process.
This 1999 fish community and habitat survey of King Pond at the Ekati Diamond Mine assessed the lake prior to its proposed use as a settling pond for the Misery Pit. The survey found a sparse, recently colonized Arctic grayling population of uniform age (four years) with high growth rates, along with limited overwintering habitat and poor stream connectivity to surrounding waterbodies.
This environmental assessment evaluates the potential ecological effects of cadmium releases from the proposed Diavik Diamond Mine on Lac de Gras, examining cadmium sources, environmental fate, bioaccumulation in aquatic organisms, and predicted adverse effects on aquatic life including fish, invertebrates, and sediment-dwelling organisms.
This 1998 compliance report documents BHP Diamonds Inc.'s adherence to water licence N7L2-1616 for the Ekati Diamond Mine, detailing water use, dewatering operations, construction projects, waste disposal, tailings management, environmental monitoring, and 17 inspections conducted during the year. Overall compliance is deemed satisfactory, though some non-compliance events occurred regarding runoff water quality and sewage discharge standards, which the licensee addressed through remedial infrastructure and operational modifications.
