No shift in tailings strategy since Mount Polley failure (Vancouver Sun)

After the catastrophic failure of the Mount Polley mine tailings dam last summer, an expert engineering panel appointed by the B.C. government called for a major shift in how to deal with mine waste.

The panel recommended a move away from the conventional method of storing waste behind dams. But companies in British Columbia with proposals for large, open-pit metal mines have no plans, at least for now, to follow the panel’s recommendation, a review by The Vancouver Sun has found.

Among the conventional proposals is Seabridge Gold’s $5.4-billion KSM copper-gold project that includes a 239- metre-high earth dam, which would be among the highest in the world. It would store more than two billion tonnes of tailings under water, 27 times more than the amount of tailings stored at Mount Polley northeast of Williams Lake in the Interior.

The KSM mine has already been approved by the B.C. and Canadian governments, and the company is seeking a partner to finance the massive project.
