Major contributor to host economies Tanzania continues to received increased benefits from our operations Over time we have agreed to follow a number of the 2010 Mining Code regulations Despite the terms of the stabilisation agreements signed with the Government Contributes to the Tanzanian Government s aim of self-funding the national budget The voluntary concessions include: Local service levies at each mine increased from US$200k to 0.3% of revenues (~US$1mpa per mine) Increasing royalty payments to 4% in 2012, which has increased the royalty paid to the Government by US$50 million in last 4 years Led to total local tax contribution of US$164 million in 2016 Incurred a corporate tax charge amounting to US$55 million Royalties of US$47 million Payroll taxes of US$40 million Other taxes of approximately US$22 million Bank of America Merrill Lynch Global Metals and Mining Conference 11

Metallic Mineral Concentrate Ban Impacting approximately 30% of group revenues In March 2017, the Ministry of Energy and Minerals announced a ban on the export of metallic mineral concentrates In order to promote the creation of a domestic smelting industry Impacts approximately 45% of Bulyanhulu s revenues and 55% of Buzwagi s revenues North Mara is not impacted as it only produces doré Continuing to engage with Government to achieve a resolution Operating Bulyanhulu and Buzwagi as normal and stockpiling concentrate at each of the sites Taken a range of actions to help manage the significant financial impact of the deferral of sales During Q1 this negatively impacted cashflow by US$33 million due to loss of sales Will re-assess the operational plans of the two mines if we cannot reach a resolution in the coming weeks Bank of America Merrill Lynch Global Metals and Mining Conference 12
