16. 3. Focused onRisk Management Technical approach using proven technology • essentially building the plants that operated at these sites before Geopolitical diversification • business development team studying opportunities in N.America Management experience • several members of management and the Board have 30 or more years of mining experience, so understand the value of building low-cost operations Shaft rehabilitation Power generation (see following slides) Acid plant

17. Risk Management ─ Shaft Rehabilitation • at the Ezulwini Mine, ground movement problems were historically encountered by the previous operators who had on occasion curtailed shaft hoisting operations to do maintenance • to eliminate the ground control problems, FIU has: • installed a hanging steel tower to permit unrestricted shaft operation in the future • has a mine plan that includes excavating a de-stress cut through the extent of the 500-metre diameter shaft pillar • reinforced an annulus around the shaft to prevent further rock movement from interfering with the shaft operation

18. Generated Risk Management ─ Power Generation • Requirement for 24MW of self-generated power • 14MW able to be met by existing capacity at site • 10MW requirement to be drawn from new generator system • 10MW requirement reflects peak period operation and generators will not need to run continuously to fill the gap Ezulwini Mine Power Gap Analysis 80,000 70,000 60,000 Demand (kVA) 50,000 40,000 30,000 20,000 10,000 0 Dec-10 Feb-11 Aug-08 Aug-09 Aug-10 Dec-07 Dec-08 Dec-09 Feb-08 Feb-10 Feb-09 Jun-10 Jun-08 Jun-09 Apr-08 Oct-08 Apr-09 Oct-09 Apr-10 Oct-10 Eskom Commitment as of June 9, 2008 Required Eskom Available Assumed

20. Risk Management ─ Sulphur Pricing • Sulphuric acid demand forecasted to exceed supply in South Africa • Market dynamics have led to sharp increases in acid price • Even at elevated prices, acid may not be available Sulphur Spot Price (Historical to Date) Notes: 1. ‘fob’ means “free on board” and indicates that the quoted price includes the cost of loading the goods into transport vessels at the specified location 2. ‘cfr’ means “cost and freight” and indicates that the cost of the goods and freight charges are included in the quoted price; while the buyer arranges for and pays insurance 3. As South Africa is a net importer of sulphur, local suppliers practice import parity pricing with industry recognized benchmark prices as shown

21. Risk Management ─ Sulphuric Acid Plant • Construction of 600tpd acid plant allows FIU to: • Secure supply of low-cost sulphuric acid upon expected completion of plant in January 2010 • Benefit from feed-stock availability in the pyrite within tailings dams • Improve the economics at both Ezulwini and MWS • Generate incremental revenue through the sale of excess acid production into the spot market • Present value assuming a discount rate of 8.0% • Low acid price assumptions reflect prices of $350/t in 2009, $265/t in 2010, $170/t from 2011-14, and $95/t thereafter; high acid price assumptions reflect prices of $350/t in 2009, $265/t in 2010, and $200/t thereafter • Acid plant operations assume acid costing of $14/t for the life of mine, incremental capital costs of $124 million, and incremental revenue from the sale of acid produced from excess capacity to third parties at prices outlined in footnote (1) above Secured low-cost sulphuric acid supply
