Cannington is 100 per cent owned by South32 and is one of the world’s largest producers of silver and lead.
Cannington consists of an underground hard rock mine and surface processing facility, a road-to-rail transfer facility and a concentrate handling and ship loading facility at the Port of Townsville.
Both open-stope and bench mining methods are used at Cannington, with approximately 3.3Mt of ore processed each year. The ore travels to the surface from depths of up to 620 metres via two methods; either by a nine tonne capacity vertical shaft hoisting system or by 50t haul trucks. The ore is then stockpiled for processing.
The processes for extracting the silver, lead and zinc from the ore involve grinding, sequential flotation and leaching techniques that produce high-grade, marketable lead and zinc concentrates with a high silver content.
The Cannington deposit was discovered in the McKinlay Shire in 1990 and took its name from the sheep and cattle station upon which the operation was developed. The area surrounding the mine operation is primarily agricultural grazing properties supporting the beef industry.
The development of the Cannington deposit followed more than a decade of research and investigation into a substantial Broken Hill-style base metals deposit, originally discovered as an anomaly during an aerial survey of the region. Following feasibility studies in the early to mid-1990s, construction of the mine, processing and associated infrastructure began after receiving Queensland Government approvals in 1996, with first production commencing in October 1997.
