RB 89/00075 Geological investigations of the Earea Dam Goldfield, South Australia.

Author: Crettenden, P.P.

Gold was discovered near Earea Dam 50 km SE of Tarcoola in 1899. Production to date totals 59 237.59 grams of gold bullion from 1869.63 tonnes of ore, with an average head grade of 35.33 g/t gold. Gold-bearing quartz was mined from an east-dipping shear within the Archaean Kenella Gneiss. Rock chip sampling by SADME revealed anomalous gold values associated with amphibolite dykes. Tarcoola Gold Ltd carried out a two-phase drilling programme of 4 diamond and 16 reverse circulation drillholes, intersecting significant mineralization SW of the Wilgena Enterprise Mine. As the grade of ore is sporadic and patchy, further drilling is required to delineate the potential ore zone.
