's Mount Polley mine because of declining copper prices. Mount Polley was the site of one of the biggest spills in B.C. history when a tailings dam collapsed in August 2014, sending 24 million cubic metres of mine waste and sludge into nearby waterways. Full operations resumed in July 2017 with a repaired and reinforced tailings dam amid assurances by the provincial government that mining code revisions would ensure a similar disaster couldn't happen again. Imperial Metals says the looming suspension of operations will have no impact on Mount Polley's ongoing environmental monitoring and remediation program.
