1 Gold equivalent ounces calculated by multiplying quantities of gold and antimony in period by respective average market price of commodities in period, adding the two amounts to get ‘total contained value based on market price’ and dividing that total contained value by the average market price of gold in period. I.e., AuEq = ((Au Produced x Au $/oz) + (Sb Produced pre-payability x 70% payability x Sb $/t)) / (Au $/oz). The average market prices for the quarter were A$5,283/oz Au (being the average of the daily PM price, sourced from www.lbma.org.uk) and A$33,508/t Sb (being the average Shanghai Metal Market Price sourced from www.metal.com).
