Harmony Gold has said gold production dropped 10% in its second fiscal quarter due to maintenance and repair breaks at two operations. The company reported a headline loss of R496 million in the three months to Dec. 31, 2014, due to the lower output and restructuring.

“Lower gold production quarter on quarter and a lower gold price resulted in a decrease in production profit to R618 million in the December 2014 quarter, compared to R913 million in the previous quarter,” the company said in a statement.

Harmony saiad it expects its operation, Kusasalethu, to return to profitability in the last quarter of the company’s financial year (end of June) through job cuts and other cost cutting.

“In essence, we need to make money, we cannot continue making losses like we have in the last two years,” Harmony’s chief executive Graham Briggs said. Details of the job cuts will be announced at the end of February, he said.

Rolling power cuts that started last year when the state power utility Eskom cut supply to meet its consumption needs contributed to a 50kg  loss in gold output for Harmony, Briggs said.

“Of course, the quarter which we end looks even worse on Eskom,” Briggs said. “I don’t know what the effects will be on our production.”

Eskom, which supplies about 95 percent of electricity to Africa’s most advanced economy, is battling to meet its daily demand of about 30,000 megawatts, relying heavily on diesel-powered turbines to keep the lights on in South Africa.

The utility’s generating capacity has been curtailed due to technical faults at its ageing power plants, as well as by a shortfall in its installed power generation capacity, leading to regular power cuts since March 2014.
