The Bottle Creek gold mine is 95 kilometres north-west of Menzies.
It was discovered in 1983, and then studied by various groups thereafter. Mining was started by Norgold in 1988, but closed only one year later due to a limited gold resource. They left behind three long narrow water filled pits and mullock hills. The mullock has been encased in earth and re-habilitated.
The deposit is located in the Ularring Greenstone Belt. It lies in an elongated plain, with the deposit striking north north-west. Gold is found close to the contact between two sequences. One contains banded iron formation with interbedded mafic volcanics, quartzites, and conglomerate. The other upper sequence shows mafic and ultramafic rocks, with minor interflow sediments, quartz porphyry intrusives and tuff. All is flanked by granitoids. Mafic minerals have been altered to ankerite-calcite-biotite-hornblende-chlorite-epidote-quartz schist, with garnet porphyroblasts, while at the margin of the porphyry is sericite schist.
Gold is concentrated between the two sequences, 30-60 metres below the surface, as micro free particles, and grain inclusions in quartz, limonite, goethite and beudanite, with an even distribution.
The main ore mineralisation is pyrite, pyrrhotite, magnetite, in turn these carrying tetrahedrite, sphalerite, arsenopyrite, and chalcopyrite with gold and electrum as micro grains. Silver occurs with tetradedrite, arsenical pyrite, pyrrhotite, sphalerite, arsenopyrite, chalcopyrite, and electrum within the massive sulphides.
Lesser mineralisation is found to the surface, expressed as a weathered gossan to an 85 metres depth. It has a strike length of 26 kilometres with sporadic mineralisation along its length. The gossan contains massive sulphides, mainly pyrite with minor tetrahedrite, sphalerite, arsenopyrite, marcasite and magnetite, in kaolinite, muscovite, quartz, chlorite, siderite, dolomite and calcite gangue. The gossan itself is goethite rich at depth, and hematite rich near the surface. It also contains minor talc, rutile, tourmaline (schorl?), Mn oxides, secondary beudantite, alunite-group minerals, anomalous mercury, Te, Ti, and patchy gold.
