  29. Operating costs � Current cash costs per ton milled and Pt oz high as build up continues. � Drivers of cost reduction � Volume increase � 4 mining areas to 2 � 1,5m of equipped face per m face blasted � Novice workforce moving up learning curve � Less development required � Cost reduction initiatives

  30. Capital expenditure ( R000’s ) 500 400 Thousands 300 200 100 0 '03 '04 '05 '06 H1 '07 Total Modikwa 438,241 147,212 234,183 186,288 79,563 � R100m/100koz of platinum production life of mine average. � Approximately R200m/100koz per annum for the next 4 years as capex profile is ‘lumpy’ when deepening

  31. Capital expenditure � Main Items for 2007 � Replacement or refurbishment of mechanised fleet – R89 million � Merensky Trial Mining – R31 million � North Shaft Deepening – R51 million � Ore Reserves – R27 million

  32. Employee and Community Relations � Community relations improving with more challenges in some community groupings than others � The 25 day strike and delayed return to Sunday work around February 2007 heightened tensions but situation is back to normal � Training programmes for learner miners and supervisors resulting in improved supervision � Implemented and achieved 38% of the HDSA in management positions � SED expenditure of approximately R 8m in 2007

  33. Key business issues � Improved safety performance � Achieve planned volume increase � Smooth transition from down dip to breast stoping and moving drives into footwall � Further improve efficiency of the mechanised development and tramming � Improve efficiencies of stoping teams � Steady state production will be achieved in 2008
