Diamond Market – Increasing Demand

11

Per capita consumption of key commodities: China relative to the US “steady state”

• Demand driven by urbanisation trend and growing middle class

• 2015: 221 Chinese cities with population of +1m (vs 107 in Europe, Japan & US combined)

• Chinese economic plan seeks to boost China’s domestic consumption; goal to double China’s 2010 GDP and average incomes by 2020

• Diamond consumption per capita in emerging regions still way below that of mature markets

• ‘Mass luxury’ is coming – affordable diamond jewellery for emerging middle classes

Strong demand growth driven by China and India:China expected to surpass the size of the US market by 2025

End Users Look To Secure Rough

13 November 2012 – Chow Tai Fook signs two year sales agreement with ALROSA:• “The greatest challenge for all diamond industry players is the scarcity of authentic natural diamonds. The

agreement with ALROSA enables us to secure more reliable supplies of rough diamonds, particularly those specifications that are in greatest demand from our customers.”

13 November 2012 – Financial Times feature from Watches & Jewellery supplement – “Suppliers struggle to keep up with diamond demand”• “The demand for what we call fancy cut diamonds, like baguettes, square, pear and marquise shaped

diamonds, for sophisticated jewellery watches is so strong that we are burning the midnight oil to keep up with our delivery deadlines” – Pini Netzer, chief executive of Eurostone

16 November 2012 – Tiffany’s agrees US$4m funding to Diamcor – strategic alliance and right to purchase production from the Krone-Endora at Venetia Project

19 November 2012 – Tiffany’s agrees US$6m loan to DiamondCorp – Lace mine offtake agreement12

China“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….the jewelry market in China is just beginning to take off.”

(Chow Tai Fook, Rapaport – 1 May 2012)

India

"The next decade will be the diamond decade in India”

Rough Diamond Prices

• Rough market stabilised in July 2012 and has remainedflat since then (Petra direct experience)

• First tenders of FY 2013 mainly delivered better thanexpected prices, but FY 2013 guidance is unchanged

• A positive retail festive season could lead to uptick inrough market in early calendar 2013

• First Petra tender (Sep) in H1 FY 2013 achievedUS$51.1 million on sale of 318,700 carats and secondtender of FY 2013 (Oct) achieved US$45.8m on sale of326,261 carats

Aim Of Expansion Programmes – Undiluted Ore

15

• Current mining at underground pipe mines taking place in diluted mature caves resulting in lower grades

• Expansion programmes will open up fresh block caves, delivering access to undiluted ore resulting in higher grades

• Grades expected:

• Cullinan ~34cpht to ~50cpht

• Finsch ~30cpht to ~47cpht

• Koffiefontein ~5cpht to ~8cpht

• Substantial higher revenue per tonne leading to increased margins

• Reduces wear and tear on processing systems (waste rock is harder & more abrasive than kimberlite)

Still need to amend word ‘depleted’ to ‘mature’ below

• Mining currently taking place in Block 4 at 630m – FY 2012/13

Change in scope for FY 2013 to FY 2016:• SW Precursor removed from

mine plan• Footprint of SLCs enlarged; • Main Block 5 cave deferred by

two years• Earlier access to undiluted ore

& defers major Capex

Expansion plan – key points:• Development of SLC down to

780m – from FY 2013• Shaft deepening to 950m &

ore-handling infrastructure –End FY 2015

• First production from Block 5 SLC – FY 2015, ramping up to full production – FY 2017

• Steady state production from Block 5 block cave – FY 2020

South Africa – Labour Relations

• Reality is mining wages are in top quartile of SA wage environment and multiples of other developing countries

• Labour unrest in mining industry is not a pure labour issue; underlying political and social issues

• Elections for top positions in ruling party – December 2012

• Service delivery, education, housing

• ‘Task Team’ (NUM, ANC and industry) established to tackle these issues

• Unlock the backlog of housing

• Focus on improving infrastructure

• Inquiry to explore role of mining and its importance to SA economy

• The people of South Africa will have to decide where to price its labour

• NUM recent London trip to rebuild investor confidence in South Africa

• Priority to stabilise labour relations in the industry

• Requirement to balance wage expectations with the need for sustainable industry and a competitive environment

• Petra better positioned than most due to nature of diamond mining and size of operations

Strategy In Action – FY 2013

20

• Investing• Capex of ca. R1.4bn in SA and ca. US$11m in Tanzania

• Optimising• Continued focus on ‘value’ production

• Reduction of bottom-cut at Finsch to 1mm to capture high value smalls

• Ongoing plant modifications at Kimberley Underground and Williamson

• Introduction of re-crush circuit to Cullinan tailings plant

• Continue to optimise plant processing and security

• Focus on continuous improvement in safety performance

• Expansion• Total tonnages mined to increase from 10Mt to ca. 17Mt

• Increased exploration spend of ca. US$5m

• Growth• Production to rise to ca. 2.85 Mcts & revenue to +US$400m
