| Skjerpet ligger på vestsiden i skråningen ned mot Tronsåi ca. 980 m.o.h. Det er to parallelle innhugg i ØV retning og langs strøk i en skrent. Det sørlige innhugget er 5 m langs strøket, 2.5 m bredt og ca. 5 m høyt, mens det nordlige er 1 m langs strøket, 3 m bredt og 2 m høyt. Tippvolumet er ca. 60 kbm. Mineralisering består av en meget svak og ujevnt fordelt impregnasjon av pyritt i silisifisert klorittskifer. Pyrittkornene er fra mm til cm i størrelse. Vertsbergart er en massiv, mm-kornet kloritt-amfibolskifer, sannsynligvis metabasalt. |
