In this prospect, a 10–12 m wide copper mineralization zone occurs in micaceous quartzite and schist of the Kulekhani Formation. There are very few old workings/ mines operated by the local people applying traditional method. Ore veins or pods, lenses, stringers of massive ore up to 1 m long are disseminated in the host rock. On the surface, the average copper content in the ore is 0.1 to 0.3% and with an upper limit of 1.5%. The total strike length of the mineralized band is about 1300 m (east and The prospect area is represented by calcareous phyllite, sericitic quartzite, carbonaceous phyllite and impure dolomite. Two mineralization bands occur in association with quartz lenses and veins within impure dolomite and calcareous phyllite. The maximum combined thickness of the mineralized bodies is 21–30 m and the strike length is around 200 m. The average copper content in the ore is <0.5%, but some of the individual lenses and veins consist of up to 7% Cu.
