Don't think 1Moz is the key point for the PFS/FS stage. It'll be more about having enough ounces in the PFS/FS to cover the costs of building the mine.
If they can get a 7 year mine life (based on Measured and Indicated resources) then that will be the key for getting on with it. Hopefully MGV gets there. The resources certainly justify digging it up, especially the 1st couple of years in the high grade pits.
