Mount Polley report into cause of spill expected Friday

An independent report on the cause of the Mount Polley tailings spill is scheduled to be released Friday morning.

When the dam at the Mount Polley tailings pond breached last August, it released 10 billion litres of water and 4.5 million cubic metres of metals-laden sand, contaminating lakes, creeks and rivers near the town of Likely in the province's interior.

Two weeks later, the B.C. government launched an independent review panel and the results of that review will be released by three geotechnical experts today. B.C.'s Minister of Energy and Mines Bill Bennett, is also expected to speak at the press conference.

Four months after the spill, B.C.'s Ministry of Environment says the company that operated the mine, Imperial Metals, is still at the very beginning of its clean-up process that will likely take years to complete.

The spill also raised questions about the inspection process for mines in this province. NDP leader John Horgan has previously claimed that a report from four years ago that detected a crack in the dam was hidden away.
