ABSTRACT

The BHP Billiton Cannington Mine is located in North-western Queensland, approximately 240 km from the town of Mt Isa. The mine location is shown in Figure 1.

The Cannington Mine produces approximately 2.4 MT per annum of silver-lead-zinc ore from its underground operations. The ore is mined by sub-level open stoping (SLOS). Stopes are mined in a combination of primary-secondary and pillarless retreat sequences on multiple mining fronts. All of the stope voids are filled after completion.
