On Tuesday I was in yet another of those asinine arguments about what constitutes “perpetual” in mining and mine closure. I had heard all the arguments, smart and cynical, more than thirty years ago when we debated them on the UMTRA Project. But the pusillanimous arguments continue, for everyone has an opinion and wants to be heard. (more…)

On the plane to the site I dipped into Nasim Taleb’s latest book, Antifragile. I read a few chapters and have stowed the book for the return fight. But I picked up enough to know that an antifragile system is one that thrives on change, shock, time, and other perturbing factors. An antifragile system is the opposite of a fragile system that inevitable breaks as a result of time, shock, disturbance, and the propagation of a mere crack. Antifragile system thrive on disorder; fragile systems do not. (more…)
Late Saturday and I am browsing the internet. Here is an amazing report that I chanced on.
It deals with the Rosemont copper project to-be in Arizona. It is called the Infiltration, Seepage, Fate and Transport Modeling Report.
It is more than 400 pages long, so download it and read it, and wonder at the cost to produce. Should we be doing this for all mines?
This is a picture of the electric car charging station at the local MEC store. Never seen a car here, in spite of the many outdoors-men who shop for expensive clothes and gear to climb mountains, ride bikes, and hike in the woods.
Here are the four e-resources that I found in a search of the first twenty pages of a Google-search using the terms mine energy balance: (more…)

The picture above is of the Black Swan causing havoc. I once wrote a paper that claimed the Black Swan causes tailings failures. The EPA picked the paper up and used it in their report on the Pebble Mine and Bristol Bay to conclude that tailings dams fail. So here as an act of contrition are three reports on recent and upcoming tailings activities aimed at killing the Black Swan. (more…)
In December last year the Gullbridge Tailings Dam, somewhere in Newfoundland, failed. Here is a link to the “best,” i.e., most comprehensive report that I can find. Seems like an engineering report prepared about a year prior to the failure resulted in a total lack of action and, as predicted by the report, the dam failed. Here is a link to the engineering report that lead to inaction. (more…)
