Kanmantoo is a settlement in South Australia. It is southeast of Adelaide in the eastern Adelaide Hills. It is in the catchment basin of the Bremer River.
Mining
The town is named after the Kanmantoo mine which opened in the 1840s and was owned by the South Australian Company. In turn, the mine had a local Aboriginal name. The site of the old underground mine is now in a much larger opencut copper mine owned by Hillgrove Resources. It is in the Adelaide Geosyncline.
