The Beutong copper gold project ("Beutong") is a large is a large porphyry copper-gold system located in Nagan Raya Regency, Aceh on the island of Sumartra, Indonesia. Beutong comprises the Beutong East Porphyry ("BEP"), Beutong West Porphyry ("BWP") and the Beutong Skarn ("BSK").
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic ...
In all well-studied porphyry copper deposits, three types of fluid inclusions coexist; low 'salinity' (<5 wt% NaCl equiv) vapor-rich inclusions, hypersaline liquid-rich inclusions, and multi-solid bearing inclusions, some of which have extreme homogenization temperatures and high apparent salinities (60–80 wt% NaCl equiv; Fig. 2).For each deposit studied, the TX data from hypersaline ...
Indonesia's copper deposits are gold-rich porphyry copper deposits, typical of the islands of Southeast Asia. These gold-rich porphyries are hosted by diorite to quartz-diorite and, to a …
The Batu Hijau porphyry Cu Au deposit lies in southwest Sumbawa Island, Indonesia. It is a world-class porphyry Cu deposit in an island are setting, and is typical of this deposit type in most features, including igneous association, morphology, hydrothermal alteration and mineralisation style.
In 2013, a diamond drill program tested an extensive advanced argillic alteration lithocap within the Hu'u project on eastern Sumbawa Island, Indonesia. A very large and blind copper-gold deposit (Onto) was discovered, in which copper occurs largely as disseminated covellite with pyrite, and as pyrite-covellite veinlets in a tabular block ...
The Elang porphyry Cu-Au deposit is located in south western Sumbawa in Indonesia approximately 60 km due east of the Batu Hijau Porphyry Cu-Au mine (Figure 1). It is a large deposit with a current resource estimate of 1430 Mt at 0.35 g/t Au and 0.33 g/t Cu (Ball, 2011). A regional stream sediment sampling and mapping program in
Newly discovered porphyry copper deposits in North Sulawesi (Celebes) are located in two principal districts, each with several centers of porphyry copper mineralization. The deposits were discovered by reconnaissance stream silt geochemistry, which detected anomalies of the order of 500 to 1,000 ppm Cu, against a background of 100 ppm Cu, with ...
The region hosts world-class porphyry copper deposits and underexplored areas that are likely to contain undiscovered deposits. Examples of known porphyry copper deposits include Batu Hijau and Grasberg in Indonesia; Panguna, Frieda River, and Ok Tedi in Papua New Guinea; and Namosi in Fiji.

porphyry copper system, and unpublished work by Adi Maryono based on Indonesian deposits. The potassic, phyllic and propylitic alteration zones of the deposit are discussed including their impact on the measured response. Chapters 2 to 4 present a number of case studies. Chapter 2 covers four porphyry Cu-Au deposits, including Grasburg, the
Porphyry copper deposits form in continental magmatic arcs along convergent plate-margin boundaries or in island-arc environments. The deposits are associated with subduction-related volcanic centers, although in some examples, they are thought ... 2008), such as at the well-studied Grasberg deposit, Indonesia (for example, Sapiie and Cloos ...
