The Ertsberg-Grasberg district hosts two giant Cu-Au (± Mo)-rich porphyry and skarn-hosted Cu systems that formed between 3.3 and 2.5 Ma. These Cu-Au systems are associated with two separate K-rich dioritic intrusions, the Grasberg Igneous Complex and the Ertsberg Intrusive Complex, which were shallowly emplaced into a sedimentary …

Coexisting, liquid-rich and vapor-rich primary fluid inclusions in quartz provide direct evidence for fluid phase separation in high-grade quartz–roscoelite–gold veins and breccias from the Porgera alkalic-type gold deposit. Vapor-rich fluid inclusions are CO2-rich, and sometimes contain liquid CO2 at room temperature. The close spatial and paragenetic …
The Porgera Gold Mine, located in the Madang province of Papua New Guinea, was initially discovered by The Australian Bureau of Mineral Resources in 1933. The ore extracted from this mine primarily consists of chalcopyrite, galena, and silver, while the waste material primarily comprises calcite, dolomite, and siderite.
and Mines in Papua, a few geologists' publications (notably Pinder,1901; Stanley, 1912, 1923; Trail,1967) and a variety of unpublished data. The first traces of gold in New Guinea were' found by Saavedra in 1528. The first gold in Papua was found near Port Moresby in 1878. The next discovery was at Sudest Island in 1888 followed by Misima Island in
Gram 24K is a unit for weighing gold used in Jewelleries in Papua New Guinea. 1 Gram = 0.03215 troy ounce, 1 troy ounce = 31.104199066874 Gram. Today, Tuesday 03 September 2024 in Papua New Guinea, 1 Gram of gold 24K = 317.02 Papua New Guinea Kina.

A continued exploration programme has further defined the geology of the Tolukuma vein system, verified the resource indicated by Newmont, and identified potential for additional mineralisation. The resource at Tolukuma Hill, designated as Zone C, is a measured 440,000t @ 17g/t Au and 46g/t Ag with an additional indicated resource of 120,000t @ …
Papua New Guinea Gold Production data is updated yearly, averaging 61,641.000 kg from Dec 1990 to 2022, with 33 observations. The data reached an all-time high of 74,540.000 kg in 2000 and a record low of 31,900.000 kg in 1990. Papua New Guinea Gold Production data remains active status in CEIC and is reported by U.S. Geological …
The Kulumadau deposit represents an intermediate-sulfidation epithermal gold deposit (3.8 Mt at 2.3 g/t, Ag:Au = 1). Mineralisation is primarily confined to hydrothermal breccias within preexisting fault zones, where it is disseminated throughout a hydrothermal matrix comprising chlorite-quartz-adularia-illite-I/S clays-calcite-pyrite. The host sequence …

The region of Papua New Guinea and Solomon Islands hosts an abundance of porphyry, epithermal and skarn mineral deposits, such as Ok Tedi, Frieda River, Porgera, Wafi-Golpu, Ladolam (Lihir) and Panguna (Bougainville; Fig. 1; Cooke et al., 2005, Sillitoe, 2010, Richards, 2013).Globally, such mineral-systems account for approximately one …
The Bilimoia gold deposit (1.77 Moz), Papua New Guinea (PNG), is a fault-hosted quartz-gold vein system hosted by 290-221 Ma years old basement that was regionally metamorphosed to greenschist facies at ~45 Ma. Mineralisation occurred during S 3-S 4 ductile events in a S 1-S 4 deformation sequence, rapid uplift, crustal

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 margin of the ...
