Using a statistical distribution method 60% might be more accurate. I did look very closely at all the pictures and data before discussing this with Elmer shortly after the NR. If I recall he said my estimation was fair but without further proof he wasn't preparred to make a call on it. This is reminiscent of the drill on drill off saga. Clearly, They feel they have enough proof. The fact that Teck signed off on this as an acceptable BFS suggests Teck was and is ok with this too.
