About Petra Diamonds Limited

Petra Diamonds is a leading independent diamond mining group and an increasingly important supplier of rough diamonds to the international market. The Company has a diversified portfolio incorporating interests in five producing operations: three underground mines in South Africa (Finsch, Cullinan and Koffiefontein), the Kimberley Ekapa Mining joint venture (including the Kimberley Underground mine and extensive tailings retreatment operations) and one open pit mine in Tanzania (Williamson). It also maintains an exploration programme in Botswana and South Africa.

Petra's strategy is to focus on value rather than volume production by optimising recoveries from its high quality asset base in order to maximise their efficiency and profitability. The Group has a significant resource base in excess of 300 million carats, which supports the potential for long-life operations.

Petra conducts all operations according to the highest ethical standards and will only operate in countries which are members of the Kimberley Process. The Company aims to generate tangible value for each of its stakeholders, thereby contributing to the socio-economic development of its host countries and supporting long-term sustainable operations to the benefit of its employees, partners and communities.
