Abstract/Summary

The Aynak copper deposit, located 30 km south of Kabul in Afghanistan, was discovered by Soviet geologists in the 1970s. Extensive exploration undertaken in the area between 1974-80 included several hundred boreholes, seventy trenches and nine exploratory adits. This delineated several large ore bodies and smaller lenses with a total “drill-indicated resource” of 240 Mt at 2.3% Cu (ESCAP, 1995). The mineralisation at Aynak consists of disseminated bornite and chalcopyrite, mainly concentrated in a stratabound orebody in a cyclic succession of metamorphosed dolomites, marls, siltstones and carbonaceous pelites. A model proposes Cu was leached from underlying volcanic rocks and flowed up faults to deposit Cu sulphides into overlying sediments.
