Impala No. 20 Shaft Project

The project involves sinking two vertical shafts and then developing three, 2.5km declines to access and transport the reef. Two trackless declines will be situated between the Merensky and upper-group two (UG2) reef planes, allowing access across ramps to the reef planes and the footwall-strike drives. A conveyor system will convey the rock to the main shaft for hoisting to the surface. There will be total of five stations on the main shaft and four on the vent shaft. The main shaft will measure 8.5m in diameter and will be 1 051m deep, enabling the hoisting of some 240 000 t/m of ore and waste. Project value: R6,8 billion.
