Ann: High Grade RPM Gold Exploration and Plant Design Purpose, page-16

Heres what they should have done imo:

As startpit is a bloody starter pit! Its not a capex for a full operation, production of a tiny indicated amount of the gold.

So starter pit: cheapest cost to start production, ideally in the 250M region which they had indicated it would be before
250M capex, NPV8 USD1650 gold price (more conservative) and you end up at a similar NPV (USD350M), with a higher IRR (~38%) and almost a year shorter payback.

Then explain, expect capex to be closer to 483M to allow RPM to be included, as well as processing the inferred amounts at korbel

Some might still not have been happy, but it certainly wouldnt have been the shit show we got.
