The Main Hill Mine is about 8 kilometres south south-west as a small water filled pit, bordering the north side of the upper reaches of the Chinnamon Creek. The Breccia Hill open pit is a few hundred metres to the south. Both were developed by the Lynas Corporation 1994-1998. Gold is found with pyrrhotite-lollingite-arsenopyrite.
