Located 6.9 km south west of Yarraloola Homestead. The source states the deposit is on a low isolated hill on the banks of the Robe River. Probably Robe Hill itself, these days a short distance west of the North West Coastal Highway.
Vertical sedimentary rocks traversed by large lenticular quartz veins, but with no definitive lode. Malachite, cuprite and minor bismuth is noted in the source. The mineralised zone is 1-5 metres wide, striking north-east, dipping 40-75 degrees north-west.
Marston states it is two zones, joining to the north into a crag 10 metres high. The country rock is reddened weathered pyritic quartz-feldspar-mica-chlorite schist, with a cherty horizon, containing lenses and interlacing veinlets of quartz. The source states the best mineralisation is in the southern part of the east zone, up to 20 metres wide by 150 metres long, of limonite-quartz lenses, veins and pods, 1-5 metres long and up to 50 cms thick.
Cobalt rich pyrite dominates, with chalcopyrite, Fe bearing sphalerite, and galena.
There was minor copper production in 1963, but earlier mining remains unrecorded. Explored by Great Boulder across 1970-1973.
