| ABSTRACT: | Ore Reserves and Mineral Resources Statements as at 30 June 2016. Successful drilling at Gwalia targeting orebody extensions below 1,800 metres below surface has created significant new resources and reserves which have increased mine life at Gwalia. The gross additions from deep drilling and design changes at Gwalia amounted to 490 koz to Ore Reserves and 938 koz to Mineral Resources. The extent of this addition to reserves has offset depletion across the group and reductions through the divestment of King of the Hills and Kailis, resulting in reserves being maintained at 4.01 Moz. The Company’s Ore Reserves are effectively unchanged as an increase in the Gwalia Ore Reserves resulting from successful surface drilling targeting mineralisation extensions below the 1800 has offset depletion from production. The Gwalia Mineral Resource has been updated following the completion of a surface drilling program targeting mineralisation below 1800 mbs and underground grade control and resource definition drilling completed from the 1540 level platform. The previous publicly reported Measured, Indicated and Inferred Mineral Resource Estimate reported at 30 June 2015 was 12,929 kt @ 7.9 g/t Au containing 3,304 koz of gold. This has increased by a net 592 koz of gold to 17,294 kt @ 7.0 g/t Au containing 3,896 koz of gold. The previous publicly reported Proved and Probable Ore Reserve Estimate reported at 30 June 2015 was 5,290 kt @ 9.4 g/t Au containing 1,594 koz of gold. This has increased by a net 214 koz of gold to 6,795 kt @ 8.3 g/t Au containing 1,808 koz of gold. | |
