When visited in 1908 by the mines inspector, Eyre, Gurr and Roberts controlled the lease. The lode was 3 feet wide, with much green copper carbonate (probably malachite) in the upper levels. A 5 tonne parcel had been sent amounting to 21% copper.
Marston (1979) states it is a lenticular cupriferous quartz vein, up to 1 metre wide, and length of 40 metres.
Production in 1952 amounted to 44.59 tonnes of cupreous ore grading at 6.83% Cu.
