Several reports have been published related to various aspects of the August 2014 tailings pond failure at Mount Polley mine in British Columbia. Additional investigations are still underway, from the Canadian government as well as from mine owner Imperial Metals.*

“It’s probable Mount Polley will get a permit to open in the next couple of weeks.” – Bill Bennett, British Columbia Energy and Mines Minister, June 30, 2015
After the tailings dam breached at Mount Polley mine in British Columbia, Canada, last August and discharged contaminants into a Fraser River tributary, Alaska developers urged the public to avoid speculation on the cause and wait for a thorough investigation to be conducted. The Mount Polley breach would provide lessons for mining companies all over the world, Pebble Limited Partnership (PLP) CEO Tom Collier said.
Now that the mine is likely to reopen, what lessons have been learned?
At the time of the breach, some Alaskans expressed concern about the dam failure for a few reasons. Mount Polley is owned by Imperial Metals, the same company that recently opened the Red Chris copper mine upstream from the Stikine River, noted as one of the largest salmon habitats in Southeast Alaska’s Tongass National Forest. Additionally, the engineer of record for the failed tailings dam at Mount Polley is Knight Piesold, the same company PLP contracted to design the tailings facility at the proposed Pebble mine.
