Shaft Sinkers is sinking a 9.9 m diameter concrete lined service shaft
and a 7.4 m diameter concrete lined production shaft near the rim of the Palabora open pit, to depths of approximately 1,300 m.
Shaft Sinkers is undertaking the sinking and equipping of the 1,291 m deep production shaft, mined to 8 m diameter and finished to 7.4 m, and the 1,275 m by 9.9 m finished diameter service shaft
. Both are being sunk using Atlas Copco shaft jumbos, an eight-boom unit in the larger diameter service shaft
and a seven-boom machine for the production shaft, and cactus grabs for mucking.
