Acid Rock Drainage and Geochemical Characterization Program, Ekati Diamond Mine (Dames & Moore, December 1997)
This final geochemical characterization report for BHP Diamonds' proposed diamond mine in the Northwest Territories evaluates the acid/alkaline rock drainage potential of waste rock, ore (kimberlite), and tailings through static and kinetic testing methods. The study predicts water quality from mine facilities including waste rock dumps, pits, underground workings, ore stockpiles, and tailings, identifying the Misery Schist Waste Rock Dump as a potential source of acidic drainage with elevated metal concentrations, while most other facilities are expected to remain benign.
