Acid Rock Drainage and Geochemical Characterization Program, Ekati Diamond Mine (Dames & Moore, December 1997)
31 December 1997Report
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.

Delgamuukw v. British Columbia, Aboriginal Title Decision (Supreme Court of Canada, June 1997)
16 June 1997Regulatory Filing
The Supreme Court of Canada decision in Delgamuukw v. British Columbia (June 1997) establishes the constitutional content and proof requirements for aboriginal title under s. 35(1) of the Constitution Act, 1982, addressing claims by Gitksan and Wet'suwet'en hereditary chiefs to 58,000 square kilometres in British Columbia. The court held that aboriginal title encompasses the exclusive right to use and occupy land for various purposes, must be proven through evidence of occupation at sovereignty (including oral histories), is inalienable and communal, and can only be infringed by government if justified by compelling objectives paired with consultation and fair compensation.

The Failure of Environmental Assessment in Canada (Andrew Nikiforuk, January 1997)
1 January 1997Report
This 1997 report by Andrew Nikiforuk, commissioned by the Walter & Duncan Gordon Foundation, critically examines the failures of federal environmental assessment in Canada.
