Croesus Shaft is one of two operating shafts on North Kalgurli Mines Limited's Fimiston lease._x000D_
At the cessation of gold mining in 1974, the workings at Croesus were allowed to flood. Large quantities of deslimed mill tailings used in filled stopes were washed into the shaft and surrounding drives, making re-access very difficult._x000D_
The shaft has been desludged from the 9 level to the 15 level, and a loading pocket installed below the 14 level. A vacuum lift unit was installed underground to facilitate the removal of the slime and spillage._x000D_
Stoping at Croesus was hampered by poor drainage, pumping, and shaft availability._x000D_
These difficulties have been overcome by utilising an open stoping system for the relatively steep, narrow, high grade stopes. Open stoping has proved to be effective and economic.
