Red Chris mine failure would eclipse Mount Polley damage

The results of a third-party review into the design of a northwestern B.C. gold and copper mine says it has the potential to cause significantly more environmental damage than the recent collapse of the Mount Polley tailings pond.
Engineering firm Klohn Crippen Berger made 22 recommendations for the owner of the mine, Imperial Metals, to improve the tailings dam of the Red Chris mine, 500 kilometres north of Terrace.
The review found the design of the dam is feasible, but that there are issues that must be addressed. The three-phased review looks at the tailings pond design, water quality predictions and geohazards at the mine site.
