[1] In 1865 a "Cornish type" copper mine engine house was established on the south-eastern slopes of Mt Canobolis near Orange in New South Wales.

[1] A 1995 conservation management plan stated "Surface historical mining fabric related to all post 1880s phases is fragmented, partial and often ephemeral, but the precinct has high potential to contain significant archaeological deposits related to the lifestyle and technology of the former community and mining activity.

"[2][1] The Cadia Engine House, associated buildings and immediate surrounding mine infrastructure constitute a historic site of national significance.

[1] Cadia Engine House was listed on the New South Wales State Heritage Register on 2 April 1999.
