The Fiveways Gold Mine was a large abandoned pit just south of the Main Gold Mine. Maps from the 1980's show the pit, however satellite images, and an investigation on the ground failed to locate it. There appears to be a huge tailings heap where the pit used to be.

The mines here are in the north-west portion of the Peak Hill Dome, and is hosted by the Peak Hill Schist. The lithologies as named by geologists who have studied the area is the Core Sequence, Honey Quartzite, Intermediate Sequence, Mine Sequence, Marker Quartzite, and Hanging Wall Sequence.

The rocks are intensely weathered, locally exceeding 100 metres depth, as kaolin and iron oxyhydroxides, in zones of hydrothermal alteration, in turn related to high strain zones, which encourage the percolation of water. It is dominated by pyrite, and biotite/albite, contain quartz-carbonate veins, hosted by highly strained metabasites and quartz mylonites. Other alteration minerals include Fe rich chlorite, sericite, garnet, schorl, dolomite and calcite.

The gold occurs in the Mine Sequence at the footwall of, and within north trending, west dipping shear zones. Mylonitic schist contains quartz pods, veins, lenses, stringers and locally graphitic mylonitic units.

The main ore body dips west 20 to 50 degrees, containing gold up to 15 g/t Au. The ore zone contains altered chlorite-biotite-quartz-carbonate-graphite assemblage. The principal ore minerals are pyrite, chalcopyrite and gold, with minor altaite, tetrahedrite, bismuthotelluride, molybdenite, and various bismuth-Pb-tellurium compounds.

The gold was deposited in two stages. Firstly, in the Mine Sequence and along the contact with the Marker Quartzite, and secondly gold was remobilised along cross cutting north-east trending faults.
