Bill, I have agreed with everything you have posted on this thread to date. I have only recently become a member of SI so I have not previously participated in the discussions. In relation to geologists knowing about salting I must disagree. Old time practical mining geologists certainly knew all about it - perhaps geologists who are trained in mining schools (ie. trained as mining or exploration geologists) are still taught it - but, most geologists these days got a degree from a University, and in general geology. Most geologists with just University training are next to useless in exploration or mining (until they gain experience) because the courses have next to no practical mining or assaying. Most geologists of my experience know next to nothing about the various types of assays and their limitations. How many know what a screen assay is? Or the fact that many assays are not total assays?

There must have been hundreds of geologists who looked at this thread or looked at the Bre-X site yet nobody has commented on the fact that normal test cyanide solutions dissolve gold at no more than 1 micron (thickness, both sides) per hour whereas Bre-X claimed late last year that the Busang gold was in the range 100 to 400 microns diameter. Obviously these geologists had never heard the old cyaniders comment that "if you can see the gold you can't cyanide it." But then there were serious geological discrepancies which nobody picked up at the time.
