Reconciliation of the McKinnons Gold Deposit, Cobar, New South Wales
McKinnons open pit gold mine, located within the Cobar Basin in New South Wales, is characterised by complex mineralisation controlled by the intersection of steep faults in the hinge zone of an anticline._x000D_
Resource estimation using indicator variography and indicator kriging was based on RC drilling on 25 in sections together with grade control RC drilling on 12 in by 12 in and 6 m by 6 in patterns. Rigorous sampling and checking procedures were used to verify the reliability of the drill hole data. Blast hole data was used to assist grade control in defining ore block boundaries.
