Skarn
The complex copper mineralisation which has an average thickness of 10 m, has a copper content up to 0.1 wt% (Harpøth et. al 1986).
The area belongs to the Gletsherland migmatite complex (Haller 1955) and comprises mixed Lower Proterozoic gneisses and supracrustals intruded by synorogenic leucocratic granites, most probably of Lower or Middle Proterozoic age (Harpøth et. al 1986).
