South Africa's government says it won't help a group of illegal miners inside a closed mine in the country's North West province who have been denied access to basic supplies as part of an official strategy against illegal mining.

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.
