Low grade sulphide mineralization in a small test pit. The main sulphide mineral is pyrrhotite. Six bulk-analysed samples show ore grades up to 0.18 % Ni, 0.14 % Cu, 0.024 % Co, 26.27 % Fe2O3 and 9.15 % S. The mineralization is associated with amphibolite of gabbroic origin occurring in a large synform (Botnelv synform, Foslie 1941).
