Burgundy Diamond Mines submits the October 2025 Surveillance Network Program (SNP) Monthly Report for Water Licence W2022L2-0001, including water quality analytical results from three sampling stations, field parameters, bioassay data, and compliance monitoring data for flow, volume, and waste management at the Ekati Diamond Mine.
Burgundy Diamond Mines submits the September 2025 Surveillance Network Program (SNP) Monthly Report for Water Licence W2022L2-0001, documenting water quality monitoring, flow measurements, waste management, and toxicological bioassay results from ten sampling stations across the Ekati Diamond Mine area.
Burgundy Diamond Mines submits the Aquatic Response Plan for Fish, Version 4.0, to address Action Level exceedances observed in 2024 for catch per unit effort and mercury and selenium concentrations in fish tissues in the Koala and King-Cujo watersheds at the Ekati Diamond Mine. The plan proposes response actions including studies on mercury bioaccumulation sources and methylmercury proportions in large-bodied fish tissues, and continued monitoring of mercury and selenium in water, sediment, and fish tissues.
The Independent Environmental Monitoring Agency reviews the 2024 Ekati Diamond Mine Environmental Agreement Annual Report and finds it satisfactory but the Summary Report unsatisfactory, identifying four key deficiencies: omission of water licence exceedances, insufficient detail on elevated mercury and selenium in fish tissues, missing acid deposition and incinerator stack testing results, and discrepancies in King Pond discharge dates.
The Wek'èezhìı Land and Water Board approved proposed revisions to the Ekati AEMP Design Plan Version 8.1 on July 9, 2025, allowing sediment quality and benthic invertebrate sampling to be conducted in 2025 rather than 2026, and removing the requirement for non-lethal Slimy Sculpin sampling in 2025. The Board also directed that Slimy Sculpin CPUE be reflected in the Aquatic Response Framework variables in the December 2025 submission.
The Wek'èezhìı Land and Water Board approved Version 11.0 of the Wastewater and Processed Kimberlite Management Plan for the Ekati Diamond Mine, submitted by Arctic Canadian Diamond Mine Ltd. on May 30, 2025, without requiring public review due to the administrative nature of the updates.
The Independent Environmental Monitoring Agency submits comments on Burgundy Diamond Mines' Waste Rock and Ore Management Plan v13.1, recommending enhanced seepage monitoring at Point Lake using groundwater wells, clarification on trace metals methodology comparisons, specific requirements for monthly visual inspections of the Point Lake Overburden Stockpile, and updated watershed information for Sable facilities.
Burgundy Diamond Mines submits the July 2025 Surveillance Network Program Monthly Report for Water Licence W2022L2-0001, documenting water quality monitoring, flow measurements, waste management, and discharge activities at the Ekati Diamond Mine. The report includes 23 water samples collected from various monitoring stations, field parameters, analytical results for major ions and metals, and operational data on ore production, waste rock disposal, and water recycling.
The Independent Environmental Monitoring Agency reviews and comments on proposed changes to the Aquatic Effects Monitoring Program (AEMP) Version 8.1, supporting the acceleration of sediment and invertebrate sampling to 2025 and the removal of non-lethal Slimy Sculpin sampling in 2025, given that Low Action Level thresholds have been met.
Water Licence inspection report for Ekati Diamond Mine (Arctic Canadian Diamond Company) conducted on May 22, 2025, documenting compliance with Water Licence W2022L2-0001. The inspection covered sampling procedures, Misery Laydown, underground fresh air raise, airport culverts, ammonium nitrate building, and main camp refuelling, with no major concerns identified but minor maintenance issues noted.
RECLAIM 8.0 is a user manual for a Microsoft Excel-based cost estimation tool developed by CIRNAC and GNWT to calculate closure and reclamation cost estimates for mines and advanced mineral exploration projects in the Northwest Territories and Nunavut. The manual provides guidance on estimating direct and indirect costs associated with mine closure activities, including water treatment, waste management, interim care and maintenance, and post-closure monitoring.
Burgundy Diamond Mines proposes two changes to the Ekati Mine Aquatic Effects Monitoring Program (AEMP) Design Plan Version 8.1 under Water Licence W2022L2-0001: to conduct sediment quality and benthic invertebrate sampling in 17 AEMP lakes in 2025 rather than 2026 to align with MDMER Cycle 2 EEM requirements, and to discontinue non-lethal Slimy Sculpin sampling in 2025 because mine-related effects have now been conclusively demonstrated and sufficient data has been collected.
Burgundy Diamond Mines Ltd. submits the 2024 Environmental Agreement and Water Licence Annual Report for the Ekati Diamond Mine in the Northwest Territories, detailing compliance with regulatory requirements and comprehensive environmental monitoring across air quality, water quality, wildlife, and land management. The report documents mining activities, infrastructure development, environmental effects monitoring results, and mitigation measures implemented throughout 2024.
Burgundy Diamond Mines submits Version 11.0 of the Ekati Diamond Mine Wastewater and Processed Kimberlite Management Plan to the Wek'èezhìi Land and Water Board, incorporating six revisions required by the Board's March 1, 2024 decision on Version 10.0. The plan describes management of minewater, sewage, and fine processed kimberlite across multiple mine sites and containment facilities to ensure compliance with Water Licence W2022L2-0001.
Burgundy Diamond Mines submits Version 13.1 of the Waste Rock and Ore Storage Management Plan (WROMP) for the Ekati Diamond Mine to the Wek'èezhìi Land and Water Board, incorporating 16 revisions required by the Board's Decision #2 and addressing regulatory requirements under Water Licence W2022L2-0001. The plan describes waste rock storage areas, geochemical characterization, seepage management, monitoring protocols, and adaptive management strategies for multiple kimberlite pipe developments.
The 2024 Air Quality Monitoring Program (AQMP) report for the Ekati Diamond Mine presents results of meteorological and air quality monitoring data collected throughout 2024, including particulate sampling, continuous air monitoring, dustfall measurements, and greenhouse gas emissions. The report documents that air quality parameters remained generally below regulatory standards, with 157.4 kt CO2e of greenhouse gas emissions released in 2024, approximately 8% lower than 2023.
Monthly surveillance network program report for May 2025 submitted by Burgundy Diamond Mines to the Wek'èezhìi Land and Water Board in compliance with Water Licence W2022L2-0001, including water sampling results, flow and volume measurements, lake levels, waste management data, ore production, and comprehensive water quality analysis from Bureau Veritas laboratory.
