Acacia Mining plc announced a mid-year Mineral Reserve and Mineral Resource update for its Gokona Mine at North Mara which adds to the long-term potential of this underground operation. Mineral Reserves as at end May 2019 increased by 13% in comparison to year-end 2018 from 1.117 million ounces (“Moz”) of gold at 5.6g/t to 1.257 Moz of gold at 5.5g/t; primarily driven by the successful additional drilling on the East and West extension at Gokona in Fourth Quarter 2018 and First Quarter 2019, offset by mining depletion and a more conservative change in assumptions for crown pillar stope recovery. Measured and Indicated Mineral Resources increased by 63% from 75,000 ounces (“Koz”) of gold at 3.3g/t to 122Koz of gold at 3.6g/t. Inferred Mineral Resources increased by 65% from 515Koz of gold at 6.5g/t to 849Koz of gold at 5.4g/t following the increase in drill density and confidence levels in the deeper areas of the deposit. All these increases are despite the fact that some 76Koz of gold have been mined in the intervening period.
