Indooroopilly Silver Mine
The open-cut and underground workings resumed, offering the University an opportunity to manage it as a working mine and teaching facility. Three shafts exist – the main shaft sunk to a depth of 290 ft, a ventilation shaft sunk to 150 ft and an inclined shaft sunk 65 degrees horizontal to the mine’s 140 ft level. This was established by students of the Colombo Plan to gain experience.
