There is a great silence of information about the geotechnical issues possibly involved in the failure of the Mt Polley tailings dam. No reports have been released; no letters published; no statistics provided. Oh sure, a few old numbers of incidents in 2012, but the 2013 report is not yet ready. (more…)
