Another sad story of underfunded mine closure.  According to this report, Yukon Zinc owes the territorial government $3 million in environmental security.  Now the company is bankrupt and also owing $646 million to hundreds of creditors. The tailings management system is described in a report at this link.  The system is described thus: (more…)

This week I had reason to go back and re-read three papers I co-authored in the early 1980s.  It is surprising how far advanced we were then, and how little things have changed, or how little of what did has become standard practice. The first paper is at this link.  Rick Call was the lead on the work we describe in this paper.  He was a large buff man, with an enormous beard, a perpetual pipe, and a totally irreverent attitude towards authority.  He sent Ned Larson and me to Texas, where we sweated through the heat to get the data.  Then back to Tucson to do the calculations.  I recently reconnected with Ned who is now in Las Vegas and the grandfather of sixteen grandchildren.  He is still with the U.S. Department of Energy which he joined after working with me for five years on the UMTRA Project in Albuquerque.  He is a great engineer, as was Rick.

Professor Jere Jennings who taught so many of us now-old civil engineers in mining used to say: “When you have read everything there is to read, when you have done all the calculations possible, then drink a bottle of brandy and exercise engineering judgement.” (more…)

Paarl is the only South African brandy I can get in Vancouver.  It is rough—not like cognac—but rather the flavor of the veldt & bush, of scrub & dust, of a long-forgotten home & inequities long-rectified.  Thus inebriated, I blog. (more…)

Most mines have a place where the miners eat.  Let us celebrate the cooks at these places by telling of the many fine meals we have enjoyed in these mining canteens. In celebrating cooks at mining canteens, I also seek to describe a job in mining that most do not write about.  If you like cooking, then maybe a job at a mine canteen is for you. (more…)

In the past, we have all done silly things at mines that constitute safety violations.  Here I record a drilling program I worked on in 1981 and 1982 at the then-proposed Greens Creek mine in Alaska.  I post with only minor edits what I found last weekend amongst some old papers in the attic.
