A molybdenum and copper prospect.Huston lists the locality in the same general region as the Spinifex Ridge mine in the Bamboo Creek District.

Marston (1979) names it as Gobbos prospect, stating it is 10 kilometres north north-east of the McPhee Creek prospect.

Aged 3313 Ma. Contains calc-alkaline, rare earths, chalcopyrite, molybdenite, scheelite, pyrite, minor galena, in stockwork quartz-carbonate veins. There is also variable amounts of potassium feldspar, biotite, and chlorite, associated with a small silicified and sericitised quartz-plagioclase porphyry stock.
