Decision making in engineering demands a logical process that is well documented.  Particularly if you are selecting a new site for a mine waste disposal facility.In 1983,  Andy Robertson and I wrote a paper available at this link on site selection.  The ideas were based on what we did to locate the site of the tailings facility for the then new Greens Creek mine.  The site was selected and is still in use.

A very old friend, now prominent in Australian mining spent the weekend with me.  We drank expensive whiskey, which he paid for, and rode many miles on my bikes around Vancouver on a fine sunny fall day.  We recounted stories of the old days in South Africa as young & inexperienced engineers and how we solved problems by gut feel rather than knowledge and computer models.  (more…)
