Thanks Vee, that's very interesting. If your calculations are correct, the irregular shape of the anomaly returns a volume of 4.66 M m3, as compared to the volume of 5.2 M m3 returned by using the formula for an ellipse. It is evident then that using the formula for HALF a sphere/ellipse, is very conservative! It also confirms that using the formula for an entire ellipse, and not halving it, is a pretty good approximation - only out by about 10%. Using 1,877 M oz, $20/oz for gold in the ground, and 115M shares, that translates to $326/share.
