Wattle Gully, at Chewton was first worked in 1853 albeit initially only to a depth of 10 metres. An exploratory drilling in 1934, that deflected off course, discovered new rich gold seams and by 1937 large amounts of gold were being extracted. The mine closed in 1969 because high water levels and the low price of gold made it unprofitable at the time. It has operated intermittently since then.Horwood Collection - Wattle Gully.
