Statement of significance:

The Cadia Engine House, associated buildings and immediate surrounding mine infrastructure constitute a historic site of national significance. The high level of integrity of the surviving structural elements, and the physical evidence of the mine layout, combined with the presence of unique components of the engine and crushing machinery, as well the manufacturer's original drawing of the engine and engine house, make the site one of the most important of its kind in Australia.

Construction years: 1865-1867
Physical description: Rubble stone and brick chimney and stone engine house and crusher house in open country side.

The beam engine was used to raise ore, drive the pump, drive the crushing machine and power other machinery. The engine house of several storeys was built to house the beam engine. The crusher house was constructed of stone and possesses some timbering, but this building is in much poorer condition. The chimney is constructed of local stone for the first 15m; the top 5m are built of red brick. Abutting the base of the chimney is remnant walling of the boiler house. Extant machinery items include remains of the beam engine, drive and brake mechanisms, pump parts, and elements of the crushing machinery and the boiler.
Physical condition and/or
Archaeological potential:
At the Cadia Mining Precinct, "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." CMP, Godden McKay 1995 Vol 1.
Date condition updated:21 Feb 05
Modifications and dates: In 1993 some stabilisation works, including roofing over the engine house was undertaken.


Historical notes: 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.

The mine operated for a short time until it was abandoned as uneconomical in 1867.

Subsequently, much of the equipment was removed and the structures fell into ruin. Some of the machinery was salvaged for scrap in the 1920s.

In 1993 some stabilisation works, including roofing over the engine house was undertaken.
