EBA Engineering Consultants conducted a comprehensive revegetation assessment at the Ekati Diamond Mine in 2003, evaluating transplanting trials (willow cuttings, grass sprigs, legumes), assessing existing reclamation projects (aerial seeding, sod placement, channel restoration), and reviewing topsoil salvage and seed inventory management for future mine closure and reclamation operations.
This 2003 annual report documents four years of revegetation research on processed kimberlite tailings at the EKATI Diamond Mine's Long Lake Containment Facility (LLCF). The studies evaluate soil amendments, seeding strategies, and native plant establishment methods to determine whether vegetative cover is viable for reclaiming the facility instead of the originally proposed rock cover.
This interim abandonment and reclamation plan describes BHP Billiton's strategy for reclaiming disturbed areas at the Ekati Diamond Mine following the mining of seven kimberlite pipes through 2014, detailing reclamation approaches for pit lakes, waste rock storage, processed kimberlite containment facilities, water management structures, and supporting infrastructure to restore stable landforms and wildlife habitat.
BHP Billiton Diamonds Inc. conducted a comprehensive seven-year reclamation research program on processed kimberlite tailings at the Ekati Diamond Mine in the Northwest Territories, with this 2002 annual report documenting revegetation trials, soil amendment studies, native plant establishment methods, and trace element assessments to determine optimal long-term stabilization strategies for mine tailings.
This annual report documents revegetation research and progressive reclamation efforts at the Ekati Diamond Mine in 2002, presenting results from multiple treatment sites including the Panda Diversion Channel, Culvert Camp, and Fred's Channel, with emphasis on plant survival rates, species establishment, and soil conditions supporting future mine closure rehabilitation.
This Master's thesis investigates the establishment of vegetation cover on processed kimberlite mine tailings at the Ekati Diamond Mine in the Northwest Territories through greenhouse and field studies. The research evaluates structural and nutrient-providing amendments to overcome tailings limitations and facilitate permanent vegetation stabilization using native grass species.
KOMEX International prepared a probabilistic reclamation liability estimate for the Sable, Pigeon, and Beartooth Pits at the Ekati Diamond Mine using a Monte Carlo Simulation Model, providing cost projections for 2005, 2010, and 2014 to establish security deposit requirements under the Type A Water License and Environmental Agreement.
This document is a database search result from the University of Oslo's Recent Literature on Lichens index containing bibliographic citations and abstracts of 14 scientific papers published between 1966 and 2000 on lichen reestablishment, growth, conservation, and colonization, particularly in boreal and arctic ecosystems.
This 2001 research report by Neil Burton Reid examines methods to stabilize processed kimberlite tailings at Ekati Diamond Mine through vegetation reclamation, testing various soil amendments (peat, lake sediment, sewage sludge, calcium sources) in both greenhouse and field trials at the Long Lake Containment Facility. Preliminary results show that organic amendments combined with nutrient sources, particularly sewage sludge with peat, significantly improve substrate conditions and plant growth, including ground cover, plant height, and development.
This annual report documents revegetation research projects conducted at BHP Billiton's Ekati Diamond Mine in 2001, including habitat creation in the Panda Diversion Channel, airstrip revegetation monitoring, Culvert Camp rehabilitation, till revegetation testing, and a survey of reclaimed mine sites near Yellowknife to predict post-closure landscape recovery.
This annual report documents a multi-year reclamation research program conducted by BHP Billiton Diamonds Inc. at the Ekati Diamond Mine to evaluate methods for revegetating processed kimberlite tailings in Cell B of the Long Lake Containment Facility. The 2001 report presents second-year results from 2000 studies (soil amendments, revegetation strategies, and grass species trials) and first-year results from 2001 studies (lake sediment soil amendments and grazing effects), demonstrating that plant establishment is feasible with appropriate soil amendments, particularly peat or lake sediment combined with fertilizer and grass seed.
Proceedings of the first bi-annual Northern Latitudes Mining Reclamation Workshop held in Whitehorse, Yukon in October 2001, comprising 13 peer-reviewed papers and 24 presentation abstracts addressing mine reclamation, closure, and abandoned mine lands in northern and alpine climates. Topics include revegetation techniques, reclamation methods, residual contaminants, and cost assessment.
Conference proceedings from the First Bi-Annual Northern Latitudes Mining Reclamation Workshop held in Whitehorse, Yukon, September 30 - October 3, 2001, featuring technical sessions, posters, and field trips on mine reclamation, closure, and remediation in northern climates, with emphasis on acid rock drainage, vegetation restoration, water quality prediction, and abandoned mine site rehabilitation.
Komex International provides a comprehensive reclamation liability estimate for BHP Diamonds' Ekati Diamond Mine closure, detailing assumptions and cost models for decommissioning, contaminated site remediation, pit flooding, post-closure monitoring programs, and site restoration activities across multiple operational areas and facilities.
Komex International Ltd. prepared a reclamation liability estimate for BHP Diamonds Inc.'s Ekati Diamond Mine using Monte Carlo Simulation methodology to calculate comprehensive closure and reclamation costs for 2001, 2005, 2010, and 2014, with median estimates ranging from $50.8 million to $90.3 million across various liability units including pit flooding, facility decommissioning, monitoring, and revegetation.
This presentation by the Mackenzie Valley Land and Water Board outlines current standard land use permit conditions under the Mackenzie Valley Land Use Regulations, identifying areas requiring improvement in wildlife protection, traditional ecological knowledge integration, and consistency across permit applications. The document includes detailed examples of specific permit conditions addressing location, equipment, methods, chemical storage, habitat protection, and land restoration.
This annual report documents a reclamation research study on processed kimberlite tailings from the Ekati Diamond Mine in the Northwest Territories, examining physical and chemical amendments to stabilize mine waste with vegetation cover. Field and greenhouse trials tested combinations of peat, lake sediment, sewage sludge, and calcium amendments to improve plant growth on tailings at Long Lake Containment Facility Cell B.
This annual report documents a comprehensive study on stabilizing processed kimberlite tailings at Ekati Diamond Mine through vegetation reclamation using various soil amendments. The research combines greenhouse and field components evaluating amendment combinations including peat, lake sediment, sewage sludge, and calcium sources to improve plant growth on the serpentine tailings at Long Lake Containment Facility.
A comprehensive reclamation liability estimate for the Sable, Pigeon, and Beartooth pit additions and the broader Ekati Diamond Mine, detailing estimated costs across multiple liability units (camp facilities, operations, open pits, tailings cells, waste rock storage, monitoring) projected for 2001, 2005, 2010, and 2014 with confidence intervals (10th percentile, median, and 90th percentile estimates).
This 2000 reclamation research report documents BHP Diamonds' revegetation efforts at the Ekati Diamond Mine, including soil topdressing effectiveness at Fox portal, vegetation establishment in the Panda Diversion Channel, and development of a reclamation registry. After five growing seasons, organic soil topdressing proved most favorable for plant growth, while native-grass cultivars achieved highest cover (39-52%), and Arctic Pendant Grass transplants in the diversion channel showed 60-92% survival rates.
