The Tingi Intrusive Complex is exposed over a 4 area making it a significant sized porphyry intrusive complex. Tingi is strikingly similar in tectonic setting, size, geology and mineralisation to the Ok Tedi porphyry coppergold deposit. The main difference is the level of erosion, with Tingi being less eroded than Ok Tedi and

In 2012, national JORC Code Reserves declined minimally by 12 tonnes to 4119 tonnes and amounted to 42% of EDR and 28% of total JORC Code resources. The most significant change in JORC Code Reserves occurred in the NT with a loss of 137 tonnes, or 56%, to just 107 tonnes.
Based on the feasibility study prior to the commencement of production in 2000, the Batu Hijau deposit had a resource of Gt % Cu, g/t Au. (Newmont website) Proven+probable reserves at the end of 2003 were stated as 570 Mt % Cu, g/t Au, representing Mt .
The Ok Tedi CuAuAg 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.
The USGS assessed undiscovered copper in two deposit types that account for about 80% of the world's copper supply. Porphyry copper deposits account for about 60% of the world's copper. In porphyry copper deposits, copper ore minerals are disseminated in igneous intrusions.
