We met as usual at the movie house on Schoolhouse Road to watch the MET live broadcast–today it was Borodin’s opera Prince Igor, a tale of a 12th century Russian prince who looses his men and honor in war against the Polovetsians. “Is it possible that 100 years after the start of the Great War, yet another great European war is beginning?” (more…)

Hitherto I have refrained from commenting on the controversy swirling around Taseko’s BC New Prosperity Mine. A number of reasons for avoiding a blog posting on the topic. First, I know nothing of the issues—I did take up Taseko’s offer to interview their engineers, but never got a reply to my email taking up their offer. Second, I work with a guy who has a cabin in the area and hence a definitive opinion on the matter: NIMBY. (more…)
A simple cover of rock is what we constructed at the 24 UMTRA piles. Over the radioactive wastes and radon barrier was a layer of rock. Many thought this ugly. Personally I think a pile of rock standing proud in the landscape is beautiful: not natural, but so robust and textured that it impresses the mind and eye.
Rock was used to control, nay eliminate erosion, for 1,000 years and more. The rock was placed to resist the forces of erosion by waters rushing down the cover. The rock type was selected to resist decay for as long a period as we had courage to predict. (more…)
It is snowing in Vancouver. Nothing sticking to the roads, but the trees are white and beautiful. Nothing much to do outside or inside for that matter, so just a few thoughts on mine waste disposal facility covers.

The best cover is no cover. If you can use the upper tailings or waste rock as the as the growth medium in which a stand of climax vegetation will flourish, you have the best cover. (more…)

The seminar on Cold Cover is upcoming in April in Whistler. What a great opportunity for a few days of leisure and information in a beautiful place. Just the thing for the privileged few in mining who can persuade their boss that they need & deserve the exposure to ideas and experts that would otherwise involve much web searching and downloading. I will be there — if this blog posting does not get me banned from attending. For my challenge to the experts presenting is this: negate what I said so many years ago. Do not obfuscate; do not formulate pusillanimous alternative to prove you are original; and tell us the truth. (more…)
I do not own any shares in Anglo American. Although I suspect some of the mutual trust funds where my money sits do hold Anglo shares. I consult to a number of Anglo mines. Thus this opinion is colored and you should think things through yourself, and not take my every word as a good word. (more…)

When we arrived in North America we envisaged a great career consulting to the mining industry. We had been successful consultants in South Africa providing many services to many mines. We gave advice, they built what we suggested, and sometimes we produced a report when the work was done. (more…)
