Kimberley Underground comprises three kimberlite pipe mines in close proximity: Bultfontein, Dutoitspan and Wesselton. These mines were integral to the economic development of South Africa as their output effectively financed development of the nascent gold industry. They are currently mining at depths of between 845 and 995 metres below surface.

The mines have a history of producing large diamonds and fancy yellows, such as the Oppenheimer (253 carats rough). The largest diamond ever recovered at Kimberley Underground was +800 carats and the mine is also the source of the Kimberley Octahedral, at 616 carats, one of the largest uncut diamonds in the world.

Petra’s expansion plan at Kimberley Underground will take production to an annual average steady state of ca. 130,000 ctpa by FY 2016.
