The ventilation shaft is the second of the two shafts that together form the Twin Shaft complex at South Deep. The first shaft, the Main Shaft, was completed in 2004. The ventilation shaft will be extended from its current depth of 2,760 m to 3,000 m. The deepening and equipping of the shaft, which includes ore storage silos and conveyor belts at shaft bottom, a new rock winder, and new headgear, is set to be completed by July 2012.
