Abstract. The gold deposit at Porgera is located in the highlands of Papua New Guinea. Alluvial gold was first recognized in 1939, but systematic exploration did not begin until 1961. The middle Miocene Porgera intrusive system, which was derived from melting of thickened crust, was emplaced within Late Cretaceous sediments on the northern

Autoclave pressure oxidation (POX) is an effective pre-treatment option when extracting gold from refractory ore bodies, such as pyrite and arsenopyrite. While gold processing plants are the most common utilizers of POX technology, the process can also be applied to other metals, like copper, zinc and uranium.

Gold grades and grain size increase from Stages 1 to 2. In addition, Stage 2 mineralisation is characterised by high silica and low sulphur, and consequently by higher Au:S (10:1) ratios compared to Stage 1 (2:1) which has low silica and high sulphur. The majority of gold is present as extremely fine grains contained within pyrite.
