Here is a summary of the worst-hit companies:

ANGLO AMERICAN PLATINUM (AMPLATS)

Amplats' four Rustenburg mines have been shut since September 12 when the world's largest platinum producer closed its doors to protect employees from escalating violence by wildcat strikers.

Fewer than 20 percent of the company's 21,000 employees have been reporting for work since then, despite threats of the sack.

ANGLOGOLD ASHANTI

The bullion producer's Kopanang mine, southwest of Johannesburg, reported a stay-away on September 21. Five days later it said all its South African operations were at a standstill.

The company warned that the prolonged strike by 24,000 miners could lead to the closure of less-profitable shafts.

GOLD FIELDS

Two mines run by the world's fourth largest bullion producer have been halted by illegal strikes. Starting at its KDC operations near Carletonville west of Johannesburg on September 10, the protests bubbled over to its Beatrix mine in the Free State province two weeks later.

The two operations employ 24,000 miners.
