As outlined in Jowitt et al. (2013), multiple deposit types can be present within a single resource or reserve estimate, meaning that some multi-deposit type systems (e.g., porphyry-skarn-epithermal) have been classified using the dominant deposit type in contained metal terms. We have also included sub-classifications within our database …Web

Introduction. Porphyry copper–gold deposits are large volume, low-grade disseminations formed by precipitation of copper and gold (plus molybdenum) from fluids of magmatic origin 1.These deposits form at shallow crustal levels (mostly <5 km depth) in association with variably large magmatic reservoirs emplaced at 10–15 km depth feeding the shallower …Web
commonly affected by thermal resetting, we infer that the total time span of hydrothermal activity cannot have been more than 0.45 Myr. This allows the calculation of the volatile fluxes associated with the formation of the deposit. The Cu resource of Ok Tedi is 8.51 Mt Cu and the estimated overall Cu:S ratio of the ore is 1:5 toWeb
