Mineraliseringen er en stratabundet sulfid-disseminasjon i lys glimmergneis (mer muskovitt enn biotitt) med kvartslinser. Den er prøvetatt over en strøklengde på 220m på tre punkter: Prøve 02 og 03 (UTM 428790 7379500), 01 (UTM 428790 7379440) og 04 (UTM 428790 7379290). Den lyse glimmergneisen er 6-7m mektig. Svovelkis er disseminert over hele bredden, men konsentrasjoner opp mot 10% finnes i enkelte dm-mektige lag, da med litt kobberkis. I glimmergneisens heng og ligg opptrer middels-grovkornet hornblendegneis, stedvis med granater.
