Diamond Market – Key Demand Drivers
6
Per capita consumption of key commodities: China relative to the US “steady state”
• Confidence in continued strong demand growth from China
• 5 year economic plan seeks to boost China’s domestic consumption
• Demand driven by urbanisation trend and growing middle class
• Chow Tai Fook: “Demand for mid-quality…diamonds over the next three to five years will be very strong (estimate +30% pa), creating a significant imbalance between supply and demand….We believe that the jewelry market in China is just beginning to take off.” (Rapaport – 1 May 2012)

Aim Of Expansion Programmes – Undiluted Ore
7
• Current mining at underground pipe mines taking place in diluted mature caves and low grade remnants
• Expansion programmes will open up fresh block caves, delivering access to undiluted ore in higher grade areas
• Cullinan grade expected to rise from ~34cpht to ~50cpht; Finsch grade expected to rise from ~33cpht to ~47cpht; Koffiefontein grade expected to rise from ~5cpht to ~8cpht
• Substantial higher revenue per tonne leading to increased margins
• Will put less stress on processing system (waste rock is harder & more abrasive than kimberlite)

KX36 – New Kimberlite Discovery
• New discovery in Botswana
• Homogeneous orebody
• Core drilling and micro-diamond sampling campaign indicated:
• Initial modelled (undiluted) diamond grade between 75-180 cpht
• Indications of a reasonably coarse diamond size distribution from MiDAmodelling
• Potential kimberlite tonnage between 28 Mt and 34 Mt to a depth of 516m below surface
• Surface area interpreted to be ~5 ha under 78m of Kalahari overburden
• LDD and bulk sampling campaign commenced in April 2012
• Results expected later in the year
