At this link is a magnificent collection of photos of some of the largest mining open pits and meteorite craters.  The text that accompanies the photos is prejudiced: the message is that mining open pits have forever changed the landscape–although craters have had similar impact.  You are left wondering what the writers really think.  (more…)

It costs between $1 and $40 a ton to build, operate, and close a mine tailings facility.  That is as specific as I was able to be when answering a question today in response to an enquiry from Australia.  There is a surprising paucity of data out there on the cost of tailings management.  We have details of salaries & wages.  We know the compensation of mining company executives.  We know how much it costs to engage and retain even the most expensive consultant.  But we have no data-base on tailings costs.

One of the miracles of the free-market system is that when one person sells a share, there is another who is buying.  Who are the current buyers when all are seemingly selling? (more…)

In the heat that now, unseasonably, envelops Vancouver, we rode yesterday some twenty-eight kilometers up the Lower Seymour Reserve.   All the way up to the salmon hatchery and beyond to a new view-point looking over the dam and reservoir. (more…)

I am sworn to secrecy on this fact: a big mining company is about to layoff about half their head-office staff.  (PS.  In fact the number is to reduce staff from 130 to 30.) (more…)

Massive landslide damages Kennecott\'s Bingham Canyon Mine

A massive slope failure has occurred at the open pit of the Bingham Canyon Mine in Utah.  Here is a link to a magnificent collection of photographs of the failure, which appears to have taken out part of a building, access roads, and filled the bottom of the pit with slide material.  Nobody was hurt: the mine had been monitoring movement and when deformation increased from 1 mm a day to 5 mms day they pulled out all workers.  A fine testament to the engineers who study rock and soil slope stability in the open pit mine context.  (more…)

A reader of this blog sent me this link.  It is a 2011 report on the economic benefits of the Fort Knox mine in Alaska.  Although the report is from 2011, it still presents some statistics worthy of note.  Here are some: (more…)

The government of Argentina has ordered Vale to continue to employ nearly 6,500 workers at the Rio Colorado potash mine that Vale is seeking to close.   Vale wants to close the mine as it is presumably not making money, inflation in Argentina is 25 % per annum, and Vale did not get tax breaks they were seeking.  (more…)

Just returned from a trip to a fly-in, fly-out mine where the temperatures were down to minus forty and fifty.  The only consolation for the extreme cold was the company.  Here are a few word pictures of some of the people I chatted to.  I set them down here as a way to represent the extremes of jobs and careers in the mining industry, and specifically in the far north.  (more…)
