An investigation of tectonic controls of gold mineralisation in quartz veins at Tarcoola recommended the further study of : - brecciated zones (in which reefs and veins exhibit an increased gold concentration) to establish their structural...

Gold mineralisation at the Tarcoola prospect occurs within quartz veins occupying extensional fractures and faults cutting through the quartz sandstone and claystone of the Late Proterozoic Tarcoola Formation. Most of the past gold production has...

The March-April 1987 drilling programme, of 25 angled RC holes totalling 2437 m, tested the gold content of the known mineralised quartz veins and also attempted to determine the distribution of gold within the surrounding Tarcoola Formation....

The main focus of a recently begun gold exploration programme on the Tarcoola Goldfield has been the Tarcoola Blocks mine, where gold occurs in subvertical quartz reefs, up to 2 m wide, which cross-cut folded Mid-Proterozoic sandstone and carbonaceous...
