The Hamley Mine was one of the larger mines in the Moonta-Wallaroo area, producing an estimated 10,000 tonnes of copper throughout its lifetime. It primarily operated from 1862 to 1888, although it was subsequently reworked by tributors and sold to another company in 1914. Hamley was connected by horse tramway to [East Moonta, South Australia|Moonta, South Australia|East Moonta] and Moonta Bay from 1869 to 1930. The sites of the Hamley mine and associated tramway are points on the Moonta Heritage Trail.
