The Awak Mas gold deposits are situated in the Latimojong Metamorphic Complex, Sulawesi, Indonesia. These deposits are hosted in pumpellyite- to greenschist-facies metasedimentary and metavolcanic rocks. Total estimated gold contents equals to 47.3 Mt at 1.4 ppm Au.
The deposits contain low amounts of fine-grained disseminated sulphide. Gold is usually associated with pyrite, chalcopyrite, and tetrahedrite-tennantite (arsenopyrite is absent). Accessory minerals include magnetite, hematite, covellite, and bornite, which are associated with quartz veins, silicification and brecciation zones. The alteration assemblage is characterised by the presence of albite, quartz, calcite, chlorite, epidote, zoisite, and sericite.
40 valid minerals.
