Mt. Polley Allowed to Return to Full Production
Prince George, B.C. – The Mount Polley mine near Likely, will be allowed to return to full production using the repaired and strengthened tailings facility which breached in August of 2014 . That breach sent millions of cubic metres of water and tailings down Hazeltine Creek into Quesnel Lake.
Under the permit amendment the mine can process up to 22,450 metric tonnes of ore per-day and store tailings in the repaired and strengthened tailings facility.
A review of the repaired tailings pond underwent a geotechnical review by two senior geotechnical engineers who both concluded the proposed design and construction of the repaired Tailing Storage Facility meet engineering standards.
The tailings facility’s repairs include extensive foundation investigation and additional buttressing of the main and perimeter embankments. The company has also established an Independent Tailings Review Board (ITRB) consisting of four professional engineers. The ITRB has full-independent oversight over all aspects of the design, construction, operation and closure planning for the Mount Polley Mine TSF.
There is still a condition that has to be met, as the restricted re-start permit issued in July of last year calls on the Mount Polley Mine Corporation to submit a draft technical assessment report in support of the long-term water management plan to government by June 30, 2016, in order to continue operations.
