| Mineraliseringen ligger innunder et uthengende berg på nordsiden av og 5 m fra bekken som kommer ned fra Koladalen. Man finner stedet ved å gå ca. 5 minutter fra Dyngebækken opp mot Koladalen i ei kløft. Selve skjerpet er vanskelig å se, men en rustsone og noen sudfidrike løsblokker omkring skjerpet ses tydelig. En løsblokk med spor etter boring er det eneste tydelige tegn på at det er skjerpet her. Sulfidlaget er 20-30 cm tykt, er orientert 80°/60°N og det kan følges ca. 2 m, men er utvilsomt lengre. I hengen ses mange "slicken-sides". Malmen er en deformert ("durch-bewegung") massiv middelskornet svovelkis (90%), resten er slireformete klorittflak. Vertsbergarten er metabasalt tilhørende Lyklingofiolittens gang-kompleks. Mineraliseringen omtales ikke i litteraturen. |
