Ann: Maiden Ore Reserve Estimate Hub and GTS Deposits, page-14

This is just the first run on the estimate of the reserves i.e. this figure is arrived at after a lot more drilling within a given area. As stated below, there will be more infill drilling to firm up more reserves i.e. to convert resources to reserves. Reserve oz is what is considered as economically viable gold to be mined. From memory, there is ~700Koz of resources of gold in Redcliffe gold project and out of this, probably 50-60% will be converted to reserves.
