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 total contained value by 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). Average market prices for gold and antimony sourced respectively from LMBA daily PM price () and Shanghai Metal Market Price (). Average market prices for December quarter were A$6,299/oz Au and A$30,245/t Sb and for September quarter were A$5,283/oz Au and A$33,508/t Sb using an AUD: USD exchange rate of 0.6565 and 0.6544 respectively.
