The Gold Mineral Reserves are estimated using a long term gold price of US$1,400/oz with a US:AUD exchange rate of 0.70. Cut-off grades for open-pit mineral reserves vary from 0.50g/t to 0.85g/t . The cut-off grade takes into account dilution, mine recovery and operating mining, processing/haulage, sustaining capital and G&A costs.
