| Mineraliseringen er blottet over 1x0.5m like ved strandkanten i et ellers overdekt terreng. Det synes klart at det dreier seg om fastfjell da bergartenes strøk og fall er i overensstemmelse med regional foliasjon og det ligger flere småblokker av samme malmtype like nedenfor. Den stratiforme mineraliseringen er blottet over 40cm mektighet. Sidestein er ikke blottet, men det er antatt å være grønnskifer. Mineraliseringen er massiv, finkornet svovelkis (RW336 og 337) med kobberkis anriket i noen cm mektige bånd. Kobberkis er spesielt anriket mot liggen, over minst 10cm mektighet (RW338). |
