I think people are forgetting that this is just a base/worst case scenario that sets the baseline that even without all of the upside to come, just Korbel main is viable. My favourite part of the SS (haven't read properly yet) is the sensitivity analysis. Look at the enormous impact of just a 10% increase
in grade or gold price would have on NPV. This SS doesn't include RPM which we know has significantly higher grades and could radically change these economics (RPM will be included in the PFS which is now underway). It is also inevitable that there is more gold just at Korbel main (let alone Korbel valley and all of the other prospects).
