The deposit occurs within a sequence of garnetiferous psammite within a migmatitic quartzo-feldspathic terrain beneath approximately |
10-60m of overlying Cretaceous and Recent sediment. Currently the world's largest single mine producer of silver. |
The sequence strikes north and is cut by two major NW-trending structures. The Trepell fault which separates the low grade Northern and |
deeper high grade Southern zones of the deposit and the Hamilton fault which forms the southern limb of the deposit. |
The "Cannington Growth Project" was approved in 2003, allowing for underground development into the Northern zone and |
improvements to be made to mine site facilities. |
