Forekomsten ligger ca. 300 m østsørøst for gården Fiskeløs. Arbeidene består av en gjenrast og gjengrodd dagskjæring som er 10 m lang og 1-2 m bred og høy. Den har retning 16° og ligger langs vestsida av mindre myrsøkk. Innerst i skjæringa er det blottet en minst 60 cm bred kvartsgang med orientering 18°/76° i en finkornet amfibolitt. Både melkehvir kvarts og mørk kvartsbreksje med kullblende finnes. Den rikeste sulfidmineraliseringen forekommer langs randen av breksjesona og består av aggregater og bånd av sinkblende, kobberkis og blyglans.
