Mount Polley mine disaster hits 2-year mark, fallout still causes divisions
VICTORIA — Lisa Kraus says it’s been a difficult two years in the tiny central British Columbia community of Likely, where the collapse of a massive tailings dam at the Mount Polley mine opened wounds that have yet to heal.
Twenty-four million cubic metres of mine waste and water gushed into nearby lakes and rivers on Aug. 4, 2014.
An independent, government-ordered panel of experts concluded the cause was an inadequately designed dam at the Imperial Metals (TSX:Ill) open pit copper and gold mine that didn’t account for drainage and erosion failures beneath the pond.
One of the panel’s geotechnical engineers described the location and design of the pond as loading a gun and pulling the trigger.
