Petra to produce 1.5m ct per year at newly-acquired Finsch Diamond mine

10 february 2011

Petra Diamonds, which recently acquired Finsch Diamond mine from De Beers, said it will produce 1.5 million carats annually.
Company chief executive Johan Dippenaar told the ongoing Mining Indaba in Cape Town that this was lower than the 2 million carats De Beers produced annually over the last five years.
He, however, said Petra would build production back towards 2 million carats over time, reaching 1.9m carats by 2019.
"It’s not a well known fact but Finsch has produced a number of large, special diamonds over its history and the recovery of significant large, high- value stones can substantially increase the total value of production in any one year,” he told delegates.
Dippenaar said on average, 27 diamonds larger than 50 carats had been recovered annually over the past four years at Finsch.
