The ore has been extracted from five pits over a 65m stretch along the NE-SW strike. The tailings are deposited downhill of the extraction sites. The country rock consists of gneiss with alternating light quartzo-felspathic bands and darker more amphibolitic bands. The sulphide mineralization is mainly restricted to these amphibolite bands that may reach 4-5m thickness with locally sub-ophitic texture. The ore consists of irregular lenses and lumps of massive pyrrhotite and minor chalcopyrite, in addition to disseminated sulphides. The massive pyrrhotite is medium grained and up to 0.5m thick and may have brecciated structure bearing rounded amphibolite fragments. Chalcopyrite preferably occurs in short veins or strands, partly in the amphibolite, partly in the massive sulphide.
