Steve - In your calculation you make the assumption that "operational expenditure (opex) is pro-rata for the ore tonnage mined". But you can't assume that. For starters, all the new ore that has been discovered within that boundaries of that first conceptual open pit, is going to be recovered without any increase in the cost of digging the hole isn't it?
Without knowing exactly where the new ore is sitting and at what grade, how the pit design might change and what it all means in terms of strip ratio, how can you even begin to assess the economics? IMO you simple don't have the data, tools, experience or skills to make the claim you have. I have always respected and appreciated your contribution to this BB but I think you've got this one wrong.
