The Financial Post reports in its Tuesday, Jan. 8, edition that Imperial Metals says it is suspending operations at its Mount Polley mine in British Columbia due to declining copper prices. A Canadian Press dispatch to the Post reports that the gold and copper mine was the site of a 2014 tailings dam collapse that was one of the largest environmental disasters in the province's history. Imperial Metals said Monday the suspension plan includes milling of low grade stockpiles which is expected to extend operations to the end of May, 2019. There will be no impact to the mine's environmental monitoring and remediation program. Imperial Metals says, "Full operations will resume once the economics of mining at Mount Polley improve." It says there will be no impact to the mine's environmental monitoring and remediation program. The company said when the economics of mining improve full operations will resume. Engineers and Geoscientists B.C. announced in September that three engineers involved in the design, construction and monitoring of the tailings storage facility that collapsed will face disciplinary hearings next year.
