The reporting of Mineral Resources and Ore Reserves for 2017 has been aligned to changes prescribed in the new SAMREC Code published in 2016, for implementation in 2017. The estimates (tonnes and content) quoted in the report are on an attributable interest basis and the attributable interest is noted in the tabulations. The Anglo American plc Ore Reserves and Mineral Resources Report quotes the reported estimates on a 100% basis. Ore Reserve and Mineral Resource estimates are quoted as at 31 December 2017.

The reduction of Ore Reserves has been partially offset by an decreased by 2.4% from 170.2 4E Moz to 166.2 4E Moz in the review increase in Ore Reserves at Mogalakwena, Tumela and Dishaba mines period. The reduction was primarily due to Bokoni Mine being placed on due to the additional conversion of Mineral Resources to Ore Reserves. care and maintenance by Atlatsa Resource Corporation (Atlatsa) and Anglo Platinum Merensky, UG2, Platreef and Main Sulphide Zone (MSZ) Ore Reserves (4E Moz) – South Africa and Zimbabwe Changes between 2016 and 2017 (Amplats attributable) 180 175 3.7 (5.8) 170.2 (2.2) 170 (1.2) 2.7 (1.2) 166.2 (5.1) 165 161.1 Reserves Moz 160 155 150 2017 2018 2016 Bokoni Platreef Economic UG2, MSZ Production Production Conversion assumptions of 85% interest of 42.5% interest Platreef (includes Pandora: disposal Merensky, UG2, MSZ stockpile movements) Conversion Merensky, Union: pending disposal At Mogalakwena Mine, a combination of enhanced geological modelling, At the Amandelbult mining complex, the continued execution of the pit shell optimisation, production and stockpile movements resulted in Tumela and Dishaba UG2 strategy has an additional 1.3 4E Moz being the Mogalakwena Platreef Ore Reserves increasing by 2.5 4E Moz from converted to Ore Reserves from the exclusive Mineral Resources. 124.1 4E Moz in 2016 to 126.6 4E Moz in 2017.
