Hosted by chloritic, kaolinized, brecciated, strongly fractured feldspar porphyry, chert, rhyolite. Two main shears containing mineralised lenses of copper stained goethite, up to 20 cms thick in quartz veins. There is also thin quartz-limonite veinlet stockwork in the country rock margins to the shears. Malachite, chrysocolla, and sporadic rare azurite.
Located 1.2 kilometres west north-west of the Copper Hills Mine. In 1956, 2.84 tonnes of cupreous ore grading at 13.17% Cu was produced. The source indicates the extensive workings when inspected in the mid 1970's, would indicate a greater production.
Marston notes, 500-800 metres north-east are two chert bands, with scattered chalcopyrite blebs in rhyolite breccia, with minor Zn mineralisation.
