I have moved on from countries and companies. I have left (and re-entered) countries. I have left companies and joined the principals in other companies. I have, in a word, moved around. At 67, I spend no time cogitating on these past decisions.  With so long a history of making decisions and moving on, I have so much to regret that I would go crazy thinking what would have been had I not made those many decisions.  It is futile to regret a past decision that may have been the wrong decision.

The following is an “article” that I repeat as is from a recent ACG newsletter. Andy Robertson of InfoMine and Robertson GeoConsultants wrote this.  The “article” is at its simplest an announcement of an upcoming conference.  But at its most complex this is a scary story of potential dragons let loose on the world to scare the populace into non-mining.  Here is what he wrote: (more…)

The conference on Tailings and Mine Waste 11 is ended and we can now sit back and reflect on what it all means.  The easiest way to do this is to look at the PowerPoint slides from Andy Robertson’s keynote address.   They are now on InfoMine at this link. (more…)
