To gjenraste groper ligger på sørsida av Skillefjordelva. Det finnes ingen opplysninger om tidligere aktivitet. Sulfidmineraliseringene opptrer langs grensen mellom grønstein og granitt, og domineres av kvarts-karbonat breksje med sulfidmatriks. Få grønnsteinsfragmenter finnes også i breksjen som dels er forskifret. Breksjen er ikke påvist i fast fjell men antas å følge grensen mellom grønnsteinen og granitten med retning tilnærmet NØ-SV. Både granitten og grønnsteinen fører noe rust og stikk med sulfider.
