Anglo-Platinum plans to increase output by 69% at the Mogalakwena mine in South Africa, the world’s largest open-pit operation, to meet rising demand.

Anglo Platinum general manager Ted Muhajir said the mine should produce 400,000oz in five years, up from 237,279oz last year.

The Mogalakwena mine is estimated to produce between 270,000oz and 280,000oz in 2010.

Speaking with Reuters, Muhajir said Angloplat could consider turning Mogalakwena into an underground operation to tap additional resources after exhausting the open pit mine resource.

The company also said it could increase its output by 8% and produce 200,000oz more this year than its forecast of 2.5 million ounces.
