Mineral Resources and Mineral Reserves

DRDGOLD’s Mineral Reserves increased by 76% from 3.3Moz (332.2.2Mt @0.31g/t) in FY2018 to 5.8Moz (557.3Mt @0.32g/t) in FY2019 due to the FWGR acquisition on 31 July 2018. There were no significant changes to Ergo as Mineral Reserves decreased mainly with the depletion during the year from reclamation. The current reserves reflect an operating life of 11 years for the Ergo operation and 20 years for FWGR.

DRDGOLD’s Surface Mineral Resources increased by 34% to 9.8Moz (1 097.53Mt @ 0.28g/t), in comparison to 7.3Moz (873.1.0Mt @ 0.26g/t) in FY2018. The increase is attributable to the acquisition of FWGR. DRDGOLD no longer has underground Mineral Resources as the ERPM Mineral and Prospecting rights were sold during the year.
