Economic recovery Items of Property, plant and equipment depreciated over the LoMP are depreciated inclusive of inferred resources included in the LoMP. These inferred resources are included in the calculation when the economic recovery thereof is demonstrated by the achieved recovered grade relative to the mine’s pay limit for the period 2006 to 2016. The pay limit has ranged from 2.3 g/t in 2008 to 1.9 g/t in 2017 while the recovered grade has ranged from 4.0 g/t to 3.42 g/t over the period. All-in-sustaining-cost * has remained consistently below the gold price received over this period resulting in economic recovery of the inferred resources. * All-in sustaining cost (“AISC”) per ounce , is calculated as the on-mine cost per ounce to produce gold (which includes production costs before intercompany eliminations and exploration costs) plus royalty paid, additional costs incurred outside the mine (i.e. at offices in Harare, Johannesburg, London and Jersey), costs associated with maintaining the operating infrastructure and resource base that are required to maintain production at the current levels (sustaining capital investment), the share-based expense arising from the LTIP less silver by-product revenue and the export incentive credit
