This picture and the others in this posting were taken by me at Knotsberry Farm in California.
A great place to visit and enjoy a terrifying ride along the raging river of insanity.

If you seek a thorough and intelligent analysis of dealing with uranium mill sites (and particularly the tailings facility) take a look at the following–it is an amazingly comprehensive document–and should be required reading for all involved in mine management, regardless of whether the mine is uranium, copper, gold, or something else.

Here is the outfall of the Pebble Mine and Mt Polley Mine debacles.  A report on the Seabridge Gold’s KSM Mine in BC.  The report is authored by Salmon Beyond Borders, a coalition of Alaska Native tribal members, commercial, sport and subsistence fishermen, and other groups, in consultation with Earthworks.  The press release is at this link.  The full report is at this link.  Here from the press release on the five key risks associated with the mine: (more…)

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.

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.

Please comment if you know more.
