As at 31 December 2019, the total Measured, Indicated and Inferred gold mineral resources at Sokor (above a 0.17 g/t gold cut-off grade at Rixen and for oxide rock at Ketubong, New Discovery and New Found and above a 0.5 g/t gold cut-off grade at Manson's Lode and for transitional and fresh rock at Ketubong, New Discovery and New Found) amounted to 16,320 kt at 1.7 g/t gold for 900,000 ounces of contained gold (inclusive of material used to define Ore Reserves). Silver, lead and zinc resources were reported for Manson's Lode, both within the gold mineralisation, above a 0.5 g/t gold cut-off grade, and also external to the gold mineralisation, above a cut-off of 2% lead plus zinc. Lead and zinc resources were reported for Sg Amang above a cut-off of 2% lead plus zinc. With the additional drilling at Manson's Lode and the definition of Mineral Resources at Sg Amang, the total resources for silver, lead and zinc mineralisation were 1,720 kt with an average grade of 61 g/t Ag, 2.1% lead and 2.5% zinc for 3,350,000 ounces of contained silver, 36,340 tonnes of contained lead and 43,320 tonnes of contained zinc.
Compared to the Group's Mineral Resource estimates as at 31 December 2018, there was a decrease of 1% in contained gold and increases of 74% in contained silver, 58% in contained lead and 84% in contained zinc as at 31 December 2019.
