Capital Markets Day October 2015
Background 2013 Revenue Estimate
40
• Firestone sold approximately 393,946 carats during the period December 2010 to December 2013 over 15 tenders. Size frequency and assortment data derived from the sale of these diamonds determine modelled prices
• Sample size from pilot plant production significantly larger than most diamond development projects
• Independent analysis of nine large stone fragments (30-40 ct stones) by First Element in Feb 2013 concluded that if these large stones were recovered unbroken and included in the revenue model, a range of values up to US$180 per carat could be expected. Three of these stones were calculated to have been 200 carats or larger
• Revenue estimate used in the 2013 DFS assumed a base case average price of US$107 per carat based on the following inputs:
- Modelled SFD’s derived from the surface bulk samples per facies collected in 2008
- Assortment $/ct data per sieve class based on pilot plant goods sold up to August 2013
- Expected and upside estimates of large stone potential based on extrapolation of the SFD and assortment curves
Base Case Average diamond price, including expected large stones,
modelled at US$107 per carat at a 1mm BCO
Upside Case Average diamond price, including upside large stones,
potentially US$156 per carat at a 1mm BCO
Besides the potential for large stones, Liqhobong has a high incidence of yellow and yellow fancy stones
Capital Markets Day October 2015

Summary of changes compared to 2009 estimate
• Geology – due to detailed re-logging of core (59 drill holes, 10,1km) shifted facies boundaries
• Overall reduction in volume as a result of tapering at depth leading to ~ 8% reduction in ore, mainly in Inferred portion of pipe
Capital Markets Day October 2015
2015 Diamond Resource Estimate
Summary of changes compared to previous estimate
• Density – 2009 estimates had sparse data – only one density value per facies. 338 new data points were collected during 2014, every 20m along boreholes where core quality allowed, resulting in a higher confidence local block estimate
• Bottom-cut-off – the new Treatment Plant will have an effective bottom-cut off (BCO) of 1.25mm. 2009 estimate had a BCO of 1mm leading to a reduction in carats but increase in US$/ct
• Boart factor – the 2015 estimate i.e. no boart factor will be applied as the boart component has negligible value. Boart factors applied as part of 2009 estimate – biggest impact on K5

2015 Resource Estimate
Summary of changes compared to 2009 estimate:
• US$/ct Revenue
– Independent valuation requested in August 2014 to revalue Liqhobong parcels based on current market trends. New US$/ct/sieve class information used to update the 2013 Liqhobong revenue forecast, including an expectation of large stones up to 100 carats and at a BCO of 1.25mm
– Modelled SFD for each of the main pipe’s 4 facies derived from bulk sampling and focused mining. This combined with a single modelled assortment allows for a revenue estimate to be determined for each of the 4 facies as at August 2014
– Increased average US$/ct result of market price increase, assortment modelling, BCO adjustment, and large stone potential analysis. Weighted average unescalated diamond price for the new Mine Plan is US$131 /ct
– Upside diamond price was kept at US$156 /ct
– Given current state of the diamond market, deemed prudent to not escalate these values until January 2017 when production will commence in all earnest

Summary of changes compared to 2009 estimate
• Depletions – the new in-situ model was depleted against the latest (April 2014) surface topography to compensate for pilot plant mining conducted up to that date.

2015 Resource Estimate
Net effect of changes compared to 2009 model:
• Higher confidence – geology, volume, density, grade and revenue models are at an Indicated level of confidence down to ~ 180m below surface
• Reduction in volume and tonnes due to pipe tapering and depletions
• Overall reduction in grade and carats due to BCO change (~3%), removal of boart factor (~11%) and volume (tonnes) reduction (~8%)
• Increase in average US$/ct due to application of August 2014 pricing info, change in BCO and including large stone potential
• Overall in situ US$/tonne increase of 9%
• Overall in-situ $ value almost identical at ~US$3B

• To a depth of approx. 180m below surface, the extent of the majority of the WDD holes, the Liqhobong Indicated Diamond Resource is estimated to contain some 9.5 Mct in 35 Mt of kimberlite at an average grade of 27 cpht
• Additional drilling will have to be conducted in due course to convert Inferred to Indicated Resource below these depths
• Total in-situ value ~US$3 billion and in-situ US$/tonne value of around US$37

Background: 2012 Mine Plan
2015 Mine Plan
• Based on the latest Resource Model and Revenue estimate
• Whittle Pit optimisation process was undertaken to determine the optimal size of LoM pit based on all the relevant inputs and modifying factors
• Following mine designs were considered
1. Concentric design containing 4 cuts with 10 metre benches and a 20 metre double bench for the final cut
2. Split Shell design with 10 metre benches and a 20 metre double bench for the final cut
3. Split Shell design with a 14m bench and 28m double bench design

Capital Markets Day October 2015
2015 Mine Plan
Pit design considerations to select optimal design
1. Split shell reduces ramp failure risk. Once two splits join then a concentric ramp results
2. Using the split shell design, waste has been deferred
3. More ramp construction and maintenance is needed
4. Capex cost for initial mining fleet expected to be lower for the split shell due to lower waste
5. Split shell has less in-pit traffic congestion with multiple ore and waste faces available
6. Split shell requires detailed planning and strict adherence to the plan to meet bottlenecks, some flexibility lost on ore face availability
7. Mining from one side of the pit first allows gathering of geo-tech data that can be applied to the other side
8. Split shell reduces blasting spillage on ramps (closing of ramps)
9. Letseng using same 14m kimberlite and 28m basalt bench designs in a split shell pit in same geological environment
10. Mine designs reviewed and signed off by SRK
49 Capital Markets Day October 2015
2015 Mine Plan
• Split shell waste profile more favourable over the first 4 years
• Peak waste years deferred with split shell design

• Waste stripping peak of 18.5 million tonnes for 2 years in years 8 and 9
• Total of 105 million tonnes in the 28m bench design compared to 117 million tonnes in the concentric design
• More importantly, the first 4 years waste total is 10.7 million tonnes compared to 15.3 million tonnes for the concentric design, resulting in a material cash flow saving
• The Split Shell strip ratio is 2 compared to 2.3 for the 2013 mine plan

Mine Plan variance summary
53 PROJECT OVERVIEW JUNE 2015
• The new mine plan shows reduced waste tonnes and stripping ratio
• Decrease in grade and carats largely as a result of boart removal, BCO change and volume reduction
• Overall LoM US$ per carat increase but reduced total US$ revenue due to carat reduction
• Large Rand revenue increase due to favourable US$/Rand exchange rate
