Forekomsten består av en vannfylt dagskjæring på et lite nes på østsida av Nossevatnet. Skjæringa er 14 m lang og opptil 3 m bred med orientering 276°. I østenden er det en vannfylt synk som er noen meter dyp. Berggrunnen består av finkornet, grågrønn, karbonatførende grønnstein. På tippen finnes opptil 30 cm store kvartsblokker. Kvartsen er gjennomsatt av uregelmessige karbonatårer som dels danner en breksjestruktur. Slike uregelmessige breksjeårer kan også sees i de utilgjengelige veggene i skjæringa. Kobbermineraliseringen ser i hovedsak ut til opptre i breksje med karbonatfragmenter i mørk grågrønn, finkornet amfibol matriks. Både kobberglans og bornitt danner finkornet fylling i denne matriks. I tillegg finnes kobberglans som uregelmessige strenger i og langs kanten av kvartsårer.
