NPV is based on a series of net cashflows and cashflow is based on the revenues minus cost.

In order to get a 8B valuation for Schaft Creek, you need around 1.2B of net cashflow year after year.

In order to get 1.2B of net cashflow, you probably need double the revenues or close.

So where will the money come from?  They are slightly increasing tonnage and cost will most likely go down, but not to an extend to at least triple the previous cashflow in my opinion.
