South African rescuers worked to free more than 110 miners trapped after a gold mine collapsed on Friday.
The collapse occurred around 8:40 a.m. local time Friday (1:40 a.m. EST Friday) at the Makonjwaan Gold Mine in Barberton, Mpumalanga province, about 360 km (220 mi) east of Johannesburg, said Manzini Zungu, a spokesman for the Association of Mineworkers and Construction Union.
The miners became trapped after the mine's main offices collapsed, Zungu said.
It was not immediately known what caused the collapse, Zungu said.
About 50 miners have been rescued, Reuters reported.
"The weather will remain mostly dry with a stray afternoon thunderstorm possible across the region as rescuers continue their work," AccuWeather Senior Meteorologist Dan Pydynowski said.
"Temperatures will be in the mid-20s C (mid-70s F) for the rest of the day," Pydynowski said. Lows will be in the mid- to upper 20s C (80-85 F)."
