Cannington Hoisting Shaft, Ventilation Shafts and Headframe

Cannington is the world’s largest single mine producer of silver and lead, representing about 6% of the world’s primary silver production, while its lead production represents about 7% of the world’s primary lead output. To extract approximately 1.8 million tonnes of ore to the surface annually, a 5.6 metre diameter hoisting shaft was constructed, extending to a depth of 650 metres. The shaft is equipped with a tower-mounted friction winder and two nine-tonne skips in counter balance running on rope guides. On the surface, tipping scrolls in the shaft headframe tip the skips into a surface bin for transfer to the processing plant’s stockpile area.
Nigel Pohio of BEM Group was contracted as Shaft Superintendent for this project.
