GRADE DISTRIBUTION OF THE GIANT OK TEDI Cu-Au

2021-2-18  The Ok Tedi porphyry Cu-Au deposit in Papua New Guinea is a world-class mineral deposit. In its premining stage, it contained 5.5 Mt Cu and 18.1 Moz Au; skarn accounts for ~80% of the current 1.9 Mt Cu and 7.7 Moz Au in total resources. Two composite felsic stocks intruded a tectonostratigraphic sequence of clastic and carbonate rocks at ~1.16 ± 0.10 Ma, in a postcollisional tectonic setting.

History of the Ok Tedi porphyry copper prospect,

The Ok Tedi porphyry copper-gold deposit in western Papua New Guinea was discovered and tested by a subsidiary of Kennecott Copper Corporation in 1968-1971. Exploration lapsed in 1972-1975 while Kennecott and the government of Papua New Guinea sought agreement on terms which would apply to any future mining operation.

Since 1970, several large mines have been developed in PNG (e.g. Panguna, Ok Tedi, Porgera, Lihir, Ramu) but always with controversial environmental standards and social impacts often overlooked or ignored.
