About Petra Diamonds Limited

Petra Diamonds is a leading independent diamond mining group and a supplier of gem quality rough diamonds to the international market. The Company’s portfolio incorporates interests in three underground producing mines in South Africa (Finsch, Cullinan and Koffiefontein) and one open pit mine in Tanzania (Williamson).

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 of ca. 230 million carats, which supports the potential for long-life operations.

Petra strives to conduct all operations according to the highest ethical standards and only operates 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.

Petra is quoted with a premium listing on the Main Market of the London Stock Exchange under the ticker 'PDL'. The Company’s US$336.7 million notes due in 2026 are listed (subject to temporary suspension) on the Irish Stock Exchange and admitted to trading on the Global Exchange Market.
