Located 35 km north north east of Nullagine.

Near a small tonalitic stock. Zoned Cu-Au and Zn-Pb-Ag-Au, over a distance of 1.5 kilometres laterally away from the stock. The most significant prospect at Quartz Circle is called Igloo, with a non-JORC resource of 0.127 Mt at 4.1% Cu.

The prospect consists of malachite, chalcocite, native copper, chalcopyrite, galena, and sphalerite. The chalcopyrite-quartz breccia areas contain significant gold grades.

Miller's prospect is 300 metres to the south of Cu-Au veins. Emperor contains disseminated to semi massive sphalerite-galena rich zones.

Two kilometres to the north is Gold Show Hill consisting of gold bearing quartz veins, hosted by fragmental felsic volcanic rocks, altered to quartz-sericite-pyrite-carbonate. Within the veins is pyrite and arsenopyrite, with pale sphalerite, tetrahredrite, chalcopyrite, acanthite, and galena.

It would appear access is continuing east along a track from the Lionel copper deposit. The Mindat co-ordinates are centred on numerous tracks, minor exploration pits, and bulldozed areas covering several square kilometres. The site is not near the Sunday Hill manganese prospect also listed under this section.
