Ann: OZ Minerals Asia Roadshow presentation , page-2

I found Page 27 and 31 interesting.

Page 27 is interesting as it shows the size of the ore body in a graphical way. The current open cut mine would appear to have only "scratched the surface" so to speak. Whether the ore body below the open pit can be mined profitably is a question that has not yet been answered, but the cost of the infrastructure is already paid for, so the marginal cost of going u/g and mining below the open pit is quite small, as capex is minimal. Time will tell whether it stacks up or not.

Page 31 is just showing the mining options for C in a graphical format.
