I am in Guatemala and at the Tahoe Resources Escobal Silver Mine. I have previously noted that I and my daughter are the engineers who designed and now give advice on the operation of the filter-pressed tailings stack. Much credit must also go to Flor de Maria Gonzalez and Sergio Aycinena of Geosimsa who are the engineers of record in Guatemala. We have worked closely with them these past four years and both have proven sound partners. Particularly Flor who as a young woman has made her mark by her excellence in a male-dominated Guatemalan mining environment. (more…)

Here is the outfall of the Pebble Mine and Mt Polley Mine debacles.  A report on the Seabridge Gold’s KSM Mine in BC.  The report is authored by Salmon Beyond Borders, a coalition of Alaska Native tribal members, commercial, sport and subsistence fishermen, and other groups, in consultation with Earthworks.  The press release is at this link.  The full report is at this link.  Here from the press release on the five key risks associated with the mine: (more…)

Or you could title this post:  “Mine or be a Slave.” The images in this post are disturbing.  That is intentional.  I seek to be as provocative as ever I have been.  So read on and let us fight over this idea.  The idea that if you do not mine, you become somebody else’s slave. I am prompted to write this by some reports today.  The first is this from the National Mining Association: (more…)

Please take a look at the photo-essay at this link before reading the rest of this posting.  The photo-essay is of work done to get the Bingham Canyon Mine going after the very big slide they had a while ago.  It is heartening to see the effort and success.  I hope it puts you in a good mood, at least a good enough mood to deal with the rest of this posting. I do not know whether to be amused or angry about the new site Yes to Life, No to Mining.  At one level it is ludicrous.  At another level it is infuriating.  As the announcement says: (more…)

Travelling in northern Peru we chanced on Chavin de Huantar.  We wondered around; I took pictures; and only now have I gotten down to reading on the web about the site.  This place is old, and gives some idea of just how long we could design mine closure works for if we choose.  Here is what Wikipedia says (more…)

Today we completed a three-day EduMine webcast on  Mine Water Management.  Some thirty people from all over the world joined in.  Maybe you can join us next time we do this.  But for now, here are a few ideas on research opportunities in mine water management that came up during discussions.

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.
