I write this fifty percent in jest, fifty percent in earnest, fifty percent with tounge in cheek, and fifty percent as a concerned citizen.  You decide which is which in what follows, for I cannot decide.  After the failure of the Bafokeng tailings facility, we built a dike across the failed area and picked up the tailings on the mine property.  We put these picked-up tailings back in the slimes dam.  Then we built a rockfill dike with an upstream filter across the valley just at the edge of the mine property.  Thus any tailings we did not pick up were washed down to the dike and were in due course picked up and put back in the slimes dam.  In due course, they filled in the failure volume with new tailings as the mine continued production.

The oft-asked question I get is this: how do you prevent a recurrence of the Mt Polley failure?  I have touched on some aspects of the answer in previous postings.  But let me, here, state my opinion succinctly.  Sure to be controversial, but this is what I truly believe is necessary to prevent a recurrence of Mt Polley, at least here in BC.   At least the following should be done for every tailings facility (in BC?): (more…)

I have lost count of the number of radio stations, newspapers, and magazines that have contacted me asking for opinions on the Mt Polley tailings happenings.  Somehow the email from Adrian Lee of that most reputable of Canadian magazine, McLeans, had a air of intelligence the pulled me into replying.  (I confess to being a regular reader of McLeans.)

Details of the remaining four are in a paper that I will present at the Tailings and Mine Waste 2014 conference in Colorado in October of this year. (more…)

Spent this past week in Quebec looking at mines.   This brought us to Rouyn-Noranda and food at Bistro Jezz.

The food at this little place on a quiet side-street is magnificent: the best I have tasted in many a year of travel to distant mines.

Take a special trip to this restaurant if you seek and relish good food.  Subtle flavours, beautiful presentation, unusual dishes.  Words cannot capture the beauty of fine food in a simple setting.

Here are some photos from this trip.
