Mineraliseringen befinner seg på samme nivå som Reinfjellskjerpene lenger øst. I en skrent er det sprengt litt og blottlagt et vertikalsnitt på 3 m. De øverste 2 m er en lys kvarts-feltspatisk granat-glimmergneis (prøve 01). Den underste meteren er mer kvartsittisk, uten granat og har litt finfordelt magnetkis (2-3 %, 02). 1.3 km mot VNV (UTM 467340 7352730), i tilnærmet samme nivå, er det sprengt ut 5 m3 i en 2 m høy skrent som består av granat-hornblendegneis med svovelkis-impregnasjon, samt spor av sinkblende og kobberkis (10-20 %, 03).
