9 Brief History of Buzwagi Gold Mine Gold mineralisation first was recognized on this property in the 1950 s Exploration began in under the direction of Anmercosa (Exploration Arm of Anglo American Corporation) Pangea Minerals Ltd (PML) continued Exploration from Pre-Feasibility study was carried out in December 2005 Feasibility study in 2006 Mineral Development Agreement and EIA approved in February 2007 Special Mining License 274/07 granted on 25th July 2007 Site Access 20th August 2007 Commenced Ore Mining and Stockpiling, October 2008 Plant Commissioning in Q First Gold Pour in Q Project Cost was $402M

11 Life of Mine

12 Life of Mine: Options Review In June 2013 work began to assess mine planning options to reverse Buzwagi's negative cash flow: Survival mode in the short to medium term Generate maximum possible free cashflow in the next 5 years Possibility of future re-capitalisation to continue the mine to its designed end of life Such re-capitalisation will be dependant on prevailing future gold price and the extent of funds required for ramping up back to full production Key strategies adopted in June 2013 were: Minimising capital expenditure, including capitalised waste stripping Deferring any rebuild or major component replacements not required for meeting the 5-year objective Maximising the mill feed grade Major labour and associated cost reduction across the board Minimising the hauling distances 12

18 Processing Operations

19 Processing overview Capacity Capacity of 4.4 million tonnes milled per annum (c.12,000tpd) Process Gravity, flotation & CIL to produce dore and copper concentrate Concentrate trucked to port and sold to smelter Infrastructure 107 km power line, 400 person village 73 ha water harvest area Full back-up power capacity 19

20 Processing improvements and future strategies Achieved the plant designed capacity of 4.4 Mt in 2013 due to: Higher mill throughput rates Reduced unplanned shutdowns Implementation of short interval controls (SICs) Future strategies to maintain and exceed the nameplate capacity for LOM: Improved mill throughputs Mining to Mill ore blend strategy Reduced planned & un-planned shutdown times Maintain high crushed ore stockpile Better plant control strategies by SICs 20

21 Business Improvement

22 2014 Business Improvement priorities Mine to mill productivity improvements Improve grade control and block model Mining process improvements (fragmentation, services) Mining fleet optimisation (dispatch upgrade, payloads, reduced idling time) Improve overall equipment effectiveness Maintenance Increase mean time between failure (MTBF) and spares management Reduced maintenance cost per hour, reduce downtime and mean time to repair (MTTR) Process plant Improve stockpile management and blending to drive improved mill throughput and plant recoveries Appropriate maintenance strategies in place Other costs Supply chain optimisation (warehouse and inventory improvements) Labour optimisation (right people, right structure and motivation) Integrate asset protection into business processes 22

23 Stakeholders

24 Relationship with Key Stakeholders Buzwagi has a cordial relationship with the central as well as local Government Executives. The modes of engagement being: Enhanced working relationship management that promotes mutual understanding Establishment of Memoranda of Understanding with the law enforcement agencies Participation in local development activities through CSR
