Endeavour copper-gold porphyry deposits, Northparkes,

Four economic porphyry copper-gold deposits, Endeavour 22, 26, 27, and 48, occur within the Late Ordovician Goonumbla Volcanic Complex of central-west New South Wales, Australia. Together these deposits have a combined ore reserve of 63.6 million metric tons (Mt) at 1.1 percent copper and 0.5 g/t gold. Mineralization is centered in narrow, pipelike quartz monzonite porphyry (QMP) intrusive

The gold and silver bearing quartz veins are characterized as mesothermal based on fluid inclusion studies. The fluid inclusions within quartz crystals in the veins indicate gold mineralization formed at a minimum temperature of 250°C and a pressure of 2.5 kilobars, corresponding to lithostatic pressure at a depth of 7 km (Geiger, 2000).
