Illegal miners are called "zama zama" ("take a chance" in Zulu) and operate in abandoned mines in the mineral-rich country. Illegal mining costs the South African government hundreds of millions of dollars in lost sales each year. Police are hesitant to go into the mine as some of those underground may be armed.

Several hundred people are believed to remain in an illegal mine in South Africa after the government cut off vital supplies and refused to help them, in a dramatic bid to crack down on the industry.

The South African government says it has put together a team including mine rescue experts to come up with a plan to bring to surface illegal miners who remain under a disused gold mine.
