History
Heritage Inventory History of Site: Quartz mining did not develop into a large industry at Creswick. There was brief flurry of activity in the early 1860s, mid 1880s and at the turn of the century. The main period of mining on Mills Reef appears to have been the mid 1880s, when it was reported that the Surprise Company were erecting a 10-head battery. The reef appeared to be poor, and both the archaeological and historical record suggests that the reef was not worked much beyond the water level.
