Svovelkis, magnetkis og kobberkis er impregnert langs kontaktsonen mellom amfibolitt i heng og granittisk gneis i ligg. Det er skjerpet over en strøklengde på ca 80 m . Hovedskjerpet: Stoll er drevet litt på skrå ned mot vest. Den er vannfylt , ca 5 m lang og 40 m3 tipp. I heng er det middelskornet hornblendegneis. Under denne er det 2 m mektig kvartsittisk gneis med disseminasjon av svovelkis og magnetkis (prøve 03). Under denne er det 1 m mektig grønnlig (sansynligvis pga. pyroksen og epidot) kvartsittisk gneis med litt sulfid-disseminasjon (prøve 04). Videre innover i stollen ser det ut til å være båndet hornblendegneis med et ca 0,5 m mektig rustent lag innerst. Over stollen, 10 m vest for åpningen er det en 5x2 m og 2 m dyp røsk (10 m3 tipp) i utgående av det rustlaget som stod innerst i stollen. 3 m mektig middelskornet granittisk gneis med disseminasjon av svovelkis (5 %), magnetkis og spor av kobberkis (prøve 05). Bånd av kvartsittisk gneis rik på svovelkisbånd (prøve 06).

Det sørligste skjerpet er 4x3 m og 1 m dypt med 10 m3 tipp. I heng står en 2 m mektig amfibolitt som er båndet: Finkornete amfibolittlag veksler med middelskornet, lysere (mer feltspat og kalkspat) granat-hornblendegneis. Hornblendegneisen fører disseminasjon av svovelkis, magnetkis og spor av kobberkis (prøve 01). I ligg er det 2 m mektig middelskornet granittisk gneis med kvartsittiske lag. Særlig sistnevnte er rik på svovelkis som opptrer i bånd med svovelkiskrystaller opptil 3-4 mm store, men er vanligvis mer finkornet (prøve 02).

1x1 m røsk med 1 m3 tipp i middelskornet kvartsrik granittisk gneis med sulfid-disseminasjon. I liggen opptrer grovkornet granittisk gneis med store muskovittflak og disseminasjon av svovelkis og kobberkis (07). 50 m nord for dette skjerpet er det røsket litt (1 m3 tipp) i sulfidholdig granittisk gneis. Grovkornet muskovittholdig granittisk gneis i ligg.
