Two mineralization bands of variable thickness extend at about 9 km and are traced from Goyang Khola in the west to Bering Khola – Sunmai Khola – Sukininda Khola in the east in Ilam District. Ore distribution is not uniform throughout, however, in places, the concentration of combined sulphide (mainly pyrite) mineralization varies from 5–30% in massive sulphide ore. Mineral association, grain size, and texture in the ore indicate remobilization and re-concentration of the ore minerals during the metamorphic process. A tentative estimated geological reserve is about 11.72 Million metric tons of sulphide ore with average grades of Cu = 0.21%, Pb <1%, Zn <1%, Au <0.1 ppm and Ag traces to 150 ppm. It is a medium-sized low-grade polymetallic deposit which could be economic if more than two metals (Cu, Au, and Ag) are extracted.
