The scope of work included the sinking, lining and equipping of an 8.5 metre diameter Main Shaft to a depth of 1 000 metres and a 7.5-meter diameter Ventilation Shaft to a depth of 930 metres. It included the development, construction and equipping of stations, levels and permanent infrastructure. Conventional South African sinking techniques that include five-deck stages, mechanised-drilling jumbos and cactus-grab mucking with kibbles were used. Mechanised trackless machinery was used for the development of all horizontal works. Another new development was the Moolmans Electrical Shaft Safety System, which uses PLCs to control shaft sinking and winder interlocks. A notable achievement was the completed erection of the 86m tall main shaft headgear, weighing over 1860t and one of the largest headgears in the Southern Hemisphere.
