Gold miner Harmony said on Tuesday it was on track to meet its annual production guidance of 1.1 million ounces, after producing more than 550,000 ounces in the six months ended December 31, 2017.
In a statement, Harmony Gold said output for the six months to December from its South African operations would be 9 percent to 11 percent higher than the previous six month period ended June 30, 2017.
It said production for the entire group had increased by between 3 and 5 percent in the six months to December, compared with the preceding half year.
The company said its Hidden Valley mine was well on track to deliver as forecast in 2018, after an infrastructure upgrade was completed and processing of ore started two weeks ahead of schedule.
Harmony is set to release its interim results on February 13.
