Today was a typical day in the life of a mining consultant.  One report was issued; one project put on hold; one request for proposals received; and a long discussion on how to deal with an obdurate client. (more…)

I was always healthy until I visited the doctor for a checkup.  Then they found all sorts of things wrong with me:  internal components not working; high levels of this and that and consequential concerns; indications of too much drink and smoking; blood pressure where it should not be;  weight too high; and so on.  Although I did loose some fifteen lbs on my recent trip to Peru and Chile. Maybe not enough alcohol,  lots of walking, and all that terrible Peruvian food.  How can you like raw fish in vinegar; black potatoes in squid ink; or slimy muscles in red pepper?  I cannot and probably ate too little.

This year I have visited at least sixteen tailings facilities from the far north of Canada to the far south of Chile.  Mainly I was there to see about the state, safety, and ongoing operation of the facilities.  But along the way I had an incredible opportunity to observe and photograph mine water management facilities and systems. In next week’s EduMine webcast on Mine Water Management, I will have a chance to distill these many observations into a coherent whole.  So come join us in the webcast next Tuesday, Wednesday, and Thursday.  But three hours a day each morning and I will update you on the many systems, practices, components, and ideas I have gleaned from these trips and observations.  Many new case histories courtesy of the mines I visited.

At this link is an announcement that the BC regulators are seeking proposals from consultants to help them evaluate the independent dam safety analyses they have ordered be done by independent folk on all the tailings facilities in BC. Dam Safety Inspection Review is the heading.  Here is the full announcement — it is fascinating for what it tells and what it does not tell. (more…)

Just home from a four-week journey that took me to  Peru, Chile, Keystone CO, Banff, and Ekati NWT.  It is good to be back in the house where you can throw off the formalities of travel, eat simple food, and get drunk in private. They say that Peruvian food is the best in the world.  Indeed it is if you are in a fancy, expensive place in Lima.  But go to a mine and eat what the miners eat, and it is terrible beyond belief.  Rice & beans and other unrecognizable substances of gooey texture.  I lost weight.  Maybe it was the altitude = 14,500 ft.  You walk slow and breathe deep in those conditions.

The final keynote speech at the conference on Tailings and Mine Waste was from Craig Benson. He talked about mine waste facility covers.   He has promised me a pdf of his talk. But in the meantime there are many documents by him and his coworkers readily available on the web that deal with much the same material as was in his presentation. (more…)

Today’s keynote address was by Tamara Johndrow of Freeport-McMoRan Mining Company. Her topic was FCX Tailings Stewardship Program. Let me note what I recall of her talk. Tamara heads a group of about ten engineers.  Their task is to look after, or steward, all of Freeport-McMoRan’s tailings facilities.  If I recall correctly that includes 18 operating facilities and over fifty closed facilities.  That is a large portfolio. They have a single objective:  NO FAILURES. (more…)
