Johan has over 20 years' experience in the leadership and management of producing diamond mining companies, having been CEO of ASX-quoted Crown Diamonds ("Crown") prior to Crown's merger with Petra in 2005. Petra will continue to follow an exceptional growth path as the Company looks to take production from 2.2 million carats in FY 2012 to over 5 million carats in FY 2019.Petra's step up from AIM to the Main Market in December 2011 was another important development in the Company's progress, underscoring Petra's transformation from a junior diamond exploration company to a leading independent diamond producer. The Main Market is the appropriate platform for the Company's continued growth, allowing a broader range of investors seeking direct exposure to the positive long-term fundamentals of the diamond market to invest in Petra. Petra subsequently joined the FTSE 250 Index in March 2012 and is now London's largest quoted diamond mining company.OUR ASSETS p4Petra offers an exceptional growth profile, with a core objective to steadily increase annual production to 5 million carats by FY 2019.The Group has a major resource base in excess of 300 million carats.ROUGH DIAMOND PRODUCTION (gross)million CARATS2.2 +98%122.2111.1101.2091.1080.2REVENUE (GROS)US$ million316.9 +44%12316.911220.610177.70994.40876.9
