Gold. Known from the early 1900's. The workings occur on the eastern slope of a hill in which schist is overlain by conglomerate. Trace gold is found in the schist below the conglomerate, but not in the conglomerate itself. Soft lode material between the schist and conglomerate one foot thick, dipping east, with some free gold. By 1912, 9.16 ounces had been removed, with two shafts.
Maybe the haunt of the occasional prospector, and recently exploration companies to make their books look good. No mining had taken place. In 1970, Hawkstone Minerals found more than 1% grade Ni nearby in gossan.
The area is remote. It would appear access is via faint tracks heading west, just north of the Copenhagen mine on the Corunna Downs Road. There are a number of tracks in the area, and getting lost is likely. Map is approximate only.
