750 metres south-west of the Onedin prospect. Hosted by similar rock to Onedin. Quartz bearing mudstone is found at the base, below spherulitic rhyolite. This is intruded by amygdaloidal rhyolite and basalt dykes. Small gossan pods are found at the surface, with chert, breccia, and silicified carbonate.
Pyrrhotite and chalcopyrite are the main sulphide minerals, with less abundant pyrite, sphalerite and galena, associated with quartz, carbonate, tremolite, and chlorite. Ironstone sections contain abundant pyrrhotite.
The sulphide mineralisation is found along bedding planes, fractures and parallel to the foliation in chloritic sandstone and mudstone.
The site has seen only limited drilling at the time of writing.
