Johannesburg - Harmony Gold [JSE:HAR] said on Tuesday it has started consultations on job cuts at its Kusasalethu mine aimed at lowering costs and returning the operation to productivity.
The mine has posted losses since 2012.
"The current situation is clearly unsustainable," the company said.
Improvement initiatives and investment injected into the Kusasalethu mine have been fruitless, the company said, adding that the "new plan will entail mining lower volumes at higher grades at a reduced cost".
"Harmony's intention is to restore the mine to profitability in the fourth quarter of the current financial year," Harmony said.
