Production since 1912 totals 5206.4 grams from 146.3 tonnes of ore with average head grade of 35.6 g/t gold bullion. Gold was won from shear zones and ferruginous quartz veins within Archaean Kenella Gneiss. Sub-vertical shear zones and quartz veins strike EW and vary in width from 0.15-0.6 metres. Soil sampling on a grid over the main workings revealed two anomalous zones greater than 0.01 ppm gold. The peak value was 0.074 ppm gold, 200 metres east of the main workings. Limited rock chip sampling from accessible underground workings and grab samples of mullock heaps produced peak values of 0.61 ppm gold for underground samples and 22 ppm gold for surface samples. Multielement geochemistry has shown a correlation of gold with Cu, Pb, Zn and As.
