the porphyry-style resources that sit within the volumetrically dominant Fubilan monzonite porphyry and not in their host rocks, whereas the Sydney monzodiorite is still largely devoid of significant resources, which are instead hosted in the sur-rounding country rock as skarn. Additional detail and useful discussion are provided by Pol-lard (2014) on the timing and nature of hydrothermal

HIDDEN MINERAL DEPOSITS IN Cu-DOMINATED PORPHYRY

The Ok Tedi Cu-Au-Ag deposit of western Papua New Guinea also is generally thought of as a major porphyry Cu deposit, yet hosts both porphyry and skarn mineralization. Current reserve estimates indicate that the majority of the contained metal within the deposit is hosted by skarns rather than porphyry bodies. Thus, following the Grasberg example in terms of contained metal, Ok Tedi could

The deposit is mined as a large open pit with a flotation processing plant capable of treating in the order of 22 to 24 million tonnes per annum (Mtpa), and currently recovering copper and gold into a saleable concentrate using conventional technology. The throughput rate is highly dependent on the ore lithology delivered from the mine.

Mt Fubilan is a rich coppergold-silver deposit with several phases of mineralisation centred on two intrusions, known as the Fubilan monzonite porphyry, located in the northern half or Centre Pit area and the Sydney monzodiorite stockworks with subsequent alteration in the south. Majority of the ore is found in the sulphide skarns, located adjacent to the intrusions along the contacts with the
