Forekomsten ligger rett vest for traktorvei, og består av en stoll med retning 230° som er påsatt i østsida av en skrent. En 2-3 m lang skjæring fortsetter utenfor stollen. Denne ender i et steinbrudd hvor både tipp- og urmateriale har blitt fjerna i nyere tid. Stollen er trolig ca. 10 m lang, men 4 m inn i stollen er det en vannfylt, trolig dyp sjakt. Stollen er anlagt langs en 30-50 cm bred rustfarget knusningssone med orientering 220°/85°. Sonen består av mørk blåsvart bergart med disseminasjon og stikk av pyritt og tynne kavrtslinser med små mengder pyritt, sinkblende og blyglans. Den ligger i en finkornet, grå og strukturløs bergart som trolig representerer en permisk gang.
