I overvokst terreng nedenfor østenden av Mellomåsen, over en avstand langs strøket på 200 m og 40 m fra strandlinjen finnes flere røsker som blotter et kisførende og delvis grafittholdig kvartsittlag i glimmerskiferen. Mye av kvartsitten er sterkt forskifret og fører rikelig med glimmer. Hengdelen av kvartsitten viser disseminert, båndet, for det meste fattig svovelkisdisseminasjon, mens liggdelen er kraftigere mineralisert, delvis breksjert og fører både svovelkis, magnetkis, sinkblende og kobberkis. Total sonemektighet varierer fra 0.5 m og opptil rundt 2 m. I strøkfortsettelsen av denne sonen, med overdekkede partier imellom, finnes reg. nr. 0351 mot NØ og nr. 0760 mot SV.
