Headline numbers – Group overview December 2017

2017 has again seen the Group's strategy deliver a strong Mineral Resource and Mineral Reserve position net of 2.2Moz gold produced and the divestment of Darlot in Australia and the Arctic Platinum Project (APP) in Finland. The robustness of the Mineral Resources and Mineral Reserves is testimony to the quality of the assets in the portfolio and is the result of a rigorous annual planning process that enforces a strong linkage between strategic, business and life-of-mine (LoM) planning that underpins alignment with Group objectives.
