Production has resumed at mines in the West Wits basin near Carletonville on the Far West Rand that were affected last week by a power outage caused by lightning.
Sibanye Gold said that production at its Driefontein operations had resumed on Monday following the restoration of 200Mva of power which was required to power the mine and that full steady state production was expected to be achieved within the week.
AngloGold Ashanti (ANG) said Monday that Tau Tona had resumed underground mining activities on Friday March 15 while Mponeng had resumed most of its operations on Monday.
The power outage was caused by a fire after lightning struck an Eskom transformer a regional power sub-station.
Eskom advised on Monday that the work to repair the damage was receiving urgent attention to restore permanent supply at the regional substation.
According to Sibanye Gold‚ Eskom has managed to reroute power to the area while it commissions a new substation‚ which is scheduled for commissioning at the end of March 2013.
Sibanye estimated on Monday that production losses‚ including the three full shifts lost during the power outage and the ramp up to resume full production‚ would amount to approximately 294kg (9‚452oz) for the quarter to 22 March 2013 and approximately 393kg (12‚646oz) for the entire period up to 31 March 2013.
AngloGold Ashanti said Monday that the impact of power outages at Mponeng and Tau Tona last week on first quarter 2013 gold production was likely to be in the region of 20‚000 ounces‚ with consequential impact on unit costs.
“While all efforts will be made to recover output once power is fully restored‚ production for the first quarter will be affected‚” it said on Monday. Details of the lost output will be made available after the quarter-end.
