| Forekomsten består av et lite skjerp nær Bergstul seter. En bilvei fører fram til sætra. Skjerpet ligger 30 m vest for denne og 10 m ovenfor et nyrestaurert stabbur. Det er en mindre skjæring hvor det antas at det er skutt inn i en lengde av 3-4 m med retning 196º. De indre 2 m er gjenrast av store blokker og er dermed utilgjengelig. Skjerpet er anlagt i en middelskornet amfibolitt, antatt metagabbro. Bornitt og mindre mengder kobberkis opptrer i grovkornet kvarts på tippen. Kvartsgangen er ikke blottet i dag, men ut i fra størrelser på blokker på tippen er den minst 10 cm mektig. Forekomsten er ubetydelig. |
