South Africa's Gold Fields last Thursday shut its No. 4 shaft at its key Kloof mine to allow investigations to take place after two miners were killed following a tremor.
Blasting at the entire mine, which has a total of five shafts, was suspended on Friday as the company sought a green light from authorities to re-open the shaft where the incident had taken place, spokesman Andrew Davidson told Reuters.
We shut the shaft on Thursday and Friday, and then lost some production at the entire mine on Friday after we stopped blasting awaiting clearance to resume operations, he said.
Kloof does not normally operate on Saturday. The mine resumed operations on Sunday evening, he said.
Kloof produced 175,500 ounces in the quarter to end-March, a 24 percent fall from 230,800 ounces in the three months to end-December.
The mine lies some 60 km southwest of Johannesburg and operates at depths of 1 km to 3.5 km, with about 15,000 workers.
Gold Fields executives took the media on a tour of new housing quarters for the workers, but the tour did not include a visit to the mine's underground operations.
The company's third-quarter output took a hit as state-owned utility Eskom [ESCJ.UL] failed to provide enough power to South Africa's mines, which led to a five-day countrywide mine shutdown in January.
Eskom has since been supplying around 90 to 95 percent to mines in the country.
Kloof receives some 90 percent of its normal electricity requirements, officials said.
