Today I received the followings announcement by email. I cannot find the original on the website of the BC Ministry of Energy and Mines (MEM). Maybe they have not gotten down to posting it yet. The announcement, in short, is that MEM has awarded Klohn Crippen Berger (KCB) a $1.5 million to help MEM evaluate the cause of the Mt Polley failure–more specifically to provide advice in conducting the “forensic investigation” into the breach.

At this link is an announcement that the BC regulators are seeking proposals from consultants to help them evaluate the independent dam safety analyses they have ordered be done by independent folk on all the tailings facilities in BC. Dam Safety Inspection Review is the heading. Here is the full announcement — it is fascinating for what it tells and what it does not tell. (more…)

The first day of presentations at the Tailings and Mine Waste 2014 Conference. Gordon McPhail delivered a talk in honor of Geoff Blight, who passed away earlier this year. Geoff made so many contributions to tailings that we were talking for at least an hour about him and his genius. I honor him here in the only way I know: record my opinion that he was one of the great of tailings. (more…)
The translation above the pictures reads:
It doesn’t matter that it is Sweden’s most modern mine, built according to environmental laws, which the Government says is the world’s strongest. In addition, Northlands mine outside Pajala is a financial flop, it is now also an ecological disaster.
One million cubic metres of water with toxic heavy metals such as nickel, cadmium, lead, copper, and more flows straight out of the wrecked mine dam to Muonioälven and later the Torne River, which is classified as a national river.
At this link you will find four photos that appear to show the breach of the perimeter embankment or dike and spillage of tailings into the surrounding countryside. Above is one of them.
The reports make little mention of the causes of failure. Although the four pictures appear to show more than one breach. A posting on Facebook dates the failure as 19 July 2014.
Please comment if you know more.

The numbers just do not add up. As I read the many sites on the web, I learn that British Columbia has about thirty operating mines. The BC government has about $172 million in closure bonds. Say about five or six million a mine. That seems grossly inadequate to me. I have just finished estimating closure of one mine and it came to nearly $60 million. Does this mean BC should have $1.7 billion in closure bonds? Here are some observations from various websites that may help you ponder this issue. (more…)
While we in BC have been preoccupied by the Mt Polley situation, yet another tailings failure has occurred. This time in Mexico. That brings the number of failures this year to three: Duke Energy, Mt Polley, and Cananea. Just the right number if the probability of failure is one in five thousand. (more…)
