Sprengt litt (3 m3 tipp) i skrent i kanten av elva. Her sitter mineraliseringen i grafittgneiss i kontakt med amfibolitt. Utgående sees ikke, men over en mektighet på minst 10 cm (dømt etter stuffer fra tippen) opptrer semimassiv-massiv svovelkis-magnetkis-mineralisering (3 prøver). Mineraliseringen domineres av finkornet, massiv svovelkis med breksjetekstur: Gneisfragmenter og årer av gangart og magnetkis (prøve NO0046.1). Magnetkis er anriket i sidebergkontakten (NO0046.3). Hengberget er hornblendegneis.
