Doze, good work. You are convincing me about average grade - I forgot what we used last time round.
The thickness you should use in all cases is 1 meter, and not 1.25, 1.50, 1.75. That is because the volume in cubic meters gets multiplied by the grade, and all the grade numbers supplied by KXL have already been normalized to a 1 meter equivalent thickness.
Your chart work is appreciated.
Back on the Wet Coast again, get feet on the ground. We are heading into September and I'm looking forward to a news release.
