ReconciliationA high-level reconciliation of total Mineral Resources andMineral Reserves for the Implats group of companies isshown below. These high-level variances are relatively small;particulars of these variances in addition to depletions areexplained in the detailed sections by operation. Roundingof numbers may result in computational discrepancies,specifically in these high-level comparisons.Total Mineral Resources tonnage (million) – inclusive of Mineral Reserves2009 2010 VarianceAttributabletonnageper ImplatsownershipImpala* 559 560 1 536Marula 102 105 4 77Afplats 400 359 (41) 232Two Rivers 85 79 (5) 36Tamboti 277 319 42 319Zimplats 1 880 1 879 (1) 1 635Mimosa 137 135 (2) 68Totals 3 439 3 437 (2) 2 902* Includes Impala/RBR JVThe main factors impacting on the variances, other thandepletions, are:• The variance at Impala is the result of various changesoff-set by the addition of the Impala/RBR JV estimates• The variance at Marula can largely be ascribed to therevised Merensky estimate• The negative variance at Afplats is largely due to theimposed depth limit• The positive variance at Tamboti is due to the increasedmineral rights on the farm KalkfonteinImplats attributable Mineral Resources(year-on-year variance)(Moz Pt)230.02009ImpalaMarulaAfplatsTwo RiversTambotiZimplatsMimosa225.22010Total Mineral Resources Pt ounces (million) – inclusive of Mineral Reserves2009DepletionminedGrowthandchanges 2010AttributablePt ouncesper ImplatsownershipImpala* 74.1 1.21 (1.7) 71.4 68.0Marula 11.2 0.10 (0.7) 10.4 7.6Afplats 37.8 0.00 (2.1) 35.7 23.2Two Rivers 5.8 0.21 (0.1) 5.5 2.4Tamboti 23.5 0.00 3.6 27.1 27.1Zimplats 106.9 0.26 0.2 106.8 92.8Mimosa 8.0 0.16 0.1 7.9 3.9Totals 267.4 1.93 (0.9) 264.6 225.2* Includes Impala/RBR JVNotes• Depletion ounces were adjusted by global concentrator and mine call factors• Potential impact of pillar losses was taken into accountwww.implats.co.za 20 Implats Mineral Resource and Mineral Reserve Statement 2010
