Forekomsten ligger i en fjellside øst for Skreivatn, 250 m i ØNØ-retning fra Ø-enden. Det er sprengt litt i en rusten linseformet enhet i sandsteinene. De er oppbygd av krysskiktede lag som er middels- til grovkornete, lokalt med overgang til grovere gruslag. Sandsteinene varierer i farge fra hvite til grå og grønnlige (kloritt-førende). Den mineraliserte linse er ca 10 m lang og opptil 2.5 m bred. Den fører disseminasjon av kobber- og svovelkis som dels opptrer langs tynne soner på tvers av krysskiktningen. Sulfidmengden overstiger sjelden et par prosent.
