Mineraliseringen, første gang mutet i 1902, har utgående i veikanten 30 m NØ for veidelet. Det er en 2 m mektig middelskornet (noe vekslende kornstørrelse) kvartsbåndet magnetitt-mineralisering med endel amfibol, feltspat, granat og biotitt. Mineraliseringen strekker seg VNV-over oppover lia - lengden er ukjent. Liggbergart er middelskornet kalkspatmarmor, og hengbergart er feltspatrik amfibolitt.
