Actually, in regard to tonnage, I am going to have to alter my guestimate.

I have been taking the length x width x depth x density, but I have not taken into account the variability of the deposit. Without having a total 3D cross section of the deposit, it's a bit of a pluck. Might have to just take a few off each dimension to get the total.

I'll try:

800 x 500 x 130 x 2.5 = 130Mt

Now, having said that, the deposit clearly widens at depth, and is still open, so....it's going to be huge.
