Mt. Polley Tailings Dam Failure – Report of Independent Investigation and Review – You Tube Summary and Electronic Report. Following this video you can see another video from a community member that worked at the mine. Despite the fact the report indicates that there was no warning of the pending failure, this worker contradicts this claim, he states that a grade 5-er could see that the dam was bulging, 6 months before it happened. He reported his concerns not only to the Company management but also the Ministry of Mines – to no avail. He also speaks of ‘bullying” and threatening from other staff members, get with the program or else! This is quite common. Another contradicting opinion from a tailings dam forman. Note his comments on lack of material for the mine, the need to expand the dam wider not higher.
