Dette er det klart største skjerpet i dette området med tippvolum på ca. 120 m3 rundt en vannfylt synk. Nord for synken er blottet en sulfidmineralisert sone som er 80-100 cm bred. Den består av uregelmessige årer og aggregater av magnetkis, kobberkis, pyritt og stedvis sinkblende i en massiv, dels klorittisert grønnstein. Den er i tillegg noe anriket på kvarts over en bredde på 30-40 cm sentralt i sulfidsonen. Analyser viser at mineraliseringen også er noe anriket på kobolt.
