Mimosa Mineral Resourcesand Ore Reserves continuedNotes• The figures in the statement above reflect the totalMineral Resource and Ore Reserve estimates forMimosa as at 30 June 2010, corresponding estimatedMineral Resources and Reserves attributable to Implatsare summarised elsewhere in the report• Mineral Resources are quoted inclusive of Ore Reserves• Mineral Resources are quoted before accounting foranticipated pillar losses. Predicted geological losseshave been subtracted from the Mineral Resourceestimates• Mineral Resource and Reserve estimates are based ona 2m mining width• Additional surface drilling has been conducted, resultingin the upgrading of Inferred Resources in the southwesternand north-western extremities of the South Hilldeposit to the Indicated category• Extensive exploration is in progress at North Hill, theestimate shown above remains unchanged as work isstill in progress. The extent of oxides has also not yetbeen defined for the Inferred Mineral Resource at NorthHill as metallurgical test work is in progress• Additional changes are attributed to depletion• Rounding of numbers may result in minor computationaldiscrepanciesAttributable platinum ounces, net of depletion, corporate activity and additional work30 June 2007Resources 4.1Moz Pt Minor increase, depletion off-set by increased widthReserves 1.0Moz Pt Marginal increase, reserve boundary enlarged, width adjusted30 June 2008Resources 4.1Moz Pt No change, depletion off-set by increased widthReserves 1.0Moz Pt 4% decrease, mostly depletion30 June 2009Resources 4.0Moz Pt 4% decrease, depletion and increased geological lossReserves 0.9Moz Pt 5% decrease, depletion30 June 2010Resources 3.9Moz Pt 1.5% decrease, depletionReserves 0.9Moz Pt 2% decrease, depletionNote: Mineral Resources are inclusive of Ore Reserves.www.implats.co.za 46 Implats Mineral Resource and Mineral Reserve Statement 2010
