Located 30 km north of Mukinbudin.
Pb-Zn-Ag deposit, but sub-economic. East trending narrow magnetite-franklinite, and biotite-garnet lenses, associated with hydrothermally altered monzonite-syenite zones, within granite and granodiorite. Ferguson mentions the 'Dam Gossan' covering 200 by 250 metres listing franklinite, willemite, galena, sphalerite, and coronadite. There is also a mineral occurrence as narrow lenses, one kilometre to the north in rock with a long list consisting of magnetite, spessartine, epidote, quartz, augite, hornblende, hematite, grossular, cordierite, calcite, sphene, galena, pyrite, willemite, biotite, zircon, and apatite. He also mentions a south deposit on trend with the main one, but no more information is provided.
Explored by Asarco 1971-1972, Otter/Shell 1976-1979, and West Coast Holdings 1981-1983. The deposit is interesting as some species it contains are uncommon in Western Australia.
The Mindat co-ordinates are approximate.
