En grunn røsk i vestkanten av en av sidebekkene til Mosvasselva. Røsken er ca. 5 m lang, 3-4 m bred og inntil 0.5 m dyp. I skjerpet er en mineralisering bestående av slirer og årer av pyrrhotitt og kobberkis i klorittisert grønnstein. Sonen som har en mektighet på minst 0.5 m ligger i øvre del av en mektig grønnsteinsenhet. Mineraliseringen ble oppdaget og undersøkt av Boliden i 1966 og ble videre kartlagt og målt geofysisk (SP-målinger) av ASPRO i 1985. Geofysikken viste at den kan følges diskontinuerlig over en avstand på ca. 1 km. Utskutte prøver av Boliden viste et innhold på 3.13 % Cu, 0.91 % Zn, 25 g/t Ag, mens en stor prøve av ASPRO viste 6.2 % Cu, 0.16 % Zn, 6.5 g/t Ag.
