RE: Newbie, What''''s the racket about?You're right - I just looked at his comment - he was using 200 x 200 x 400. Using those numbers (2.5 dg again) the tonnage is 40 million tonnes. I assume the 400 m is one of the horizontal directions since you would not mine to 400 meters unless you could expand the high wall to the west. Lower grades there but there is some grade according to Newmonts holes.
