Tailings water of drinking quality: mine president -- Global News - By Dene Moore - The Canadian Press - August 5, 2014 10:34 am Brian Olding, who operates Brian Olding and Associates Ltd., said Imperial Metals Corp.

He said the firm was seeking a permit to treat and release some of the water to keep the size of the pond in check at its Mount Polley Mine, an open pit gold and copper mine about 140 kilometres southeast of Quesnel, B.C. The earthen dam at one end of the FOUR-KILOMETER LONG pond breached early Monday morning, sending a 45-metre wide wall of water and mining debris into local creeks and lakes. The release of 10 million cubic metres of water and 4.5 million cubic metres of silt into Polly Lake prompted drinking water warnings for Quesnel Lake, Polley Lake, Hazeltine Creek, Cariboo Creek and the Quesnel River up to its intersection with the Fraser River. Olding described the walls on the tailings pond as very high. No analysis of the dam’s structural integrity was done as part of the review, he said.

They did not want to deal with that problem at that time. ...” globalnews.ca/news/1491413/consultant-says-tailings-pond-was-growing/
