Earlier, a police spokesperson had told AFP 225 miners had been arrested.
They were forced out “as a result of starvation and dehydration”, police said, after security agencies blocked routes used by their accomplices to deliver food and water to the mine.
“These 225 illegal miners are part of others believed to be hundreds if not a thousand illegal miners who are stuck underground,” a statement issued late on Saturday said.
It added that the operation was ongoing as more miners could still resurface.
South African Police Service acting national commissioner Lieutenant General Shadrack Sibiya said more than 13,691 suspected illegal miners had been arrested in seven provinces since December 2023.
“We have seized R5 million [about $475,000] in cash and uncut diamonds worth R32m,” said Sibiya.
Thousands of illegal miners, many of them hailing from other countries, operate in the mineral-rich nation, living and working in arduous conditions.
