A copper prospect located about 3 kilometres south of the Southern Cross bore. Two shafts were sunk in 1968, 4.5 metres apart, and each to a depth of 4.5 metres. The northern shaft contains patchy mineralisation, but locally grading up to 23% Cu.
The deposit contains three mineralised, and two un-mineralised quartz veins, filling faults, in dark-grey sericite schist, and gneiss, along a length of 305 metres. The main vein is up to 0.8 metres wide at the northern end, and grades into a number of heavily malachite stained narrow quartz lenses at the southern end.
The surface shows malachite, trace chalcopyrite and chalcocite, with rich limonite and tourmaline filled quartz veins. The ore is chalcopyrite, chalcocite, bornite, azurite, with malachite common in fractures.
