The thing I don't understand is that from some of the images, IGO has clearly done an optimisation on it and they still gave it away. Yes they will add some significant ounces to the JORC but I would of thought all that unclassified mining inventory (that they will change to Inferred) was included in the studies and so it still won't change the economics of the project. Could be totally wrong here.
