Abandoned coal mine.
The mine was developed by Christie (surname) in 1864, to supply the local gold mining community with fuel.
The coal seams were said to be in the centre of Coal Pit Gully, covering 1.5 acres, with a seam of brown lignite, then overlying this a seam of black lignite. The seams were patchy, and thin at either end. The host is white sand. At the deepest part the seam is 3 feet thick.
Around 1865, Currie (surname) and D. Duncan took out a neighbouring lease, believing the coal seams extended into their claim, however they only found sand.
John Smith took over the coal pit in 1868, and built a cottage on the lease. The quality of the coal was apparently passable.
It is assumed the location is at the end of Coal Pit Road, in Coal Pit Gully, where the dam now is (water filled pit), 2 kilometres east of Naseby. It is open to the public as a recreation area.
