Barisan Porphyry Belt

Middle Ise Ise Porphyry Cu-Au Prospect

This prospect is located about 8 km southeast of Abong. Geological mapping, rock-chip and channel sampling by East Asia Minerals has outlined altered and gold-copper mineralized diorite and quartz diorite over an area of 1,200 m x 500 m. The alteration assemblages that have been recognised are advanced argillic, quartz-clay-pyrite (locally phyllic), argillic and propylitic. Sugary quartz veins and silica-alunite veins are present. Sulfides that have been noted are pyrite and minor chacocite, covellite and chalcopyrite. The best results reported from channel sampling to date is 10 m at 0.17 g/t Au and 0.21% Cu.
