Updated All-In Cost Per Ounce. Something appears to be amiss? VG’s updated cost estimate is largely based on automated ore sorting, finer grinding, less power consumption and use of limited existing facilities. These are not new “savings”, but low and behold at $1300 gold it makes a decent return. The gold base case should be no more than $1050. The study summary omits many cost categories which could add, in combination, significant cost.
