Petra Diamonds said it would mine about 3.2 million carats in the financial year ended June 2015, an increase of 3 percent from the previous year.
The company, which has five producing mines in South Africa and one in Tanzania, said it remained on track to meet its production target of about 5 million carats annually by the 2019 financial year.
London-listed Petra Diamonds gets most of its production from five mines it bought from Anglo American's De Beers unit, the world's biggest diamond producer by value. - Reuters
