An indicated 29 100 tonnes of tailings containing 1.88 g/t Au, 2 g/t Ag, 70 ppm Cu, 1200 ppm Pb, 350 ppm Zn, and 80 ppm As in 2 separate dumps remain on site. Cyanidation leach tests show that about 60% of Au in the truck dumps and up to 50% of the Au...

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...
