A 4-metre (13 ft) shallower mine is located at TauTona in Carletonville, though plans are in place to begin work on an extension to the TauTona mine, bringing the total depth to over 3,900 metres (12,800 ft) and breaking the current record by 127 feet (39 m).[14] At these depths the temperature of the rocks is 140 °F (60 °C).[15]
