The Turret Gold Mine is a small abandoned pit, 3 kilometres south-east of the Agnew Hotel. The pit is not well preserved, indicating it was mined several decades ago.
It is located on the hinge of the Lawlers Anticline. It is a porphyry derived Au-Cu-Bi-Mo deposit, and is atypical of orogenic gold deposits in the Yilgarn Craton.
The gold is structurally controlled by the Table Hill Shear Zone, is quartz poor, with up to 15% copper sulphides. The gold was deposited at 350-270 °C, with mesothermal alteration including carbonate-chlorite alteration.
There is a pervasive talc-carbonate alteration, and extensive pre-mineralisation arsenopyrite, chalcopyrite, pyrrhotite and pyrite alteration.
The deposit then suffered a late deformational event along a dilatational segment of the main Table Hill Shear Zone, leading to the formation of breccia hosted Cu-Bi-Mo-Au, and more minor Ag-Zn-Te-W. The Au-Ag-Cu alloys, native bismuth, chalcopyrite and other Bi-Te-S phases, show gold was 'scavenged' from Bi-Te-Cu-Au-Ag-S fluids or melts.
