Interim Closure and Reclamation Plan (ICRP) 2024 Annual Progress Report, Appendix C, Effective Neutralization Potential Report, Ekati Diamond Mine (Arctic Canadian Diamond Company, January 2025)
10 January 2025Report
This is a 2024 supplemental report on the Effective Neutralization Potential (ENP) investigation at the Ekati Diamond Mine, prepared by Geosyntec Consultants for Arctic Canadian Diamond Company. The report presents results from extended kinetic testing (up to 162 weeks) and post-kinetic mineralogical analysis to evaluate how site-specific variables such as temperature, mineralogy, particle size, and mineral reactivity affect the acid neutralization capacity of waste rock, with findings that metasediment samples maintained sufficient ENP to neutralize acidity until Week 108, after which pH decreased toward acidic conditions, and that temperature, sulphide oxidation rates, and silicate mineral weathering are key factors influencing ENP at the mine.

Kodiak Lake Mercury Investigation, 2023 Annual Report Update, Ekati Diamond Mine (Arctic Canadian Diamond Company, July 2024)
1 July 2024Report
This report presents a comprehensive investigation of elevated mercury concentrations in large-bodied fish (lake trout and round whitefish) from Kodiak Lake at the Ekati Diamond Mine, including desktop analysis of historical monitoring data (1997–2018) and a 2023 field study of total and methylmercury in water and sediments. Key findings indicate that higher fish mercury concentrations are strongly correlated with wetland influences, elevated primary productivity, and Kodiak Lake's larger drainage area relative to reference lakes, rather than direct mine discharge.
