a couple of years ago while attending a presentation at the pdac an analyst who was sitting beside me said...that key to trr discovery was that they had the whole length of cores assayed including the breccia...In my naivete I had always assumed this to be the case...i was told that not only did it take longer but that it was also more expensive....In bgms case since it is to be open pit..wouldn't it make sense to analyze the whole core..i would appreciate comments from those who know more than myself...
