The integration of Mponeng underground gold mine and Mine Waste Solutions surface gold recovery operation into Harmony Gold was presenting “wonderful opportunities” in the West Wits area, Harmony CEO Peter Steenkamp said on Tuesday. Harmony, which will be on site at Mponeng and Mine Waste Solutions from October 1, is looking to the two operations adding a total of 350 000 oz of production a year to the Johannesburg- and New York-listed gold company, 250 000 oz/y from the underground mine and 100 000 oz/y from the surface operation.
