| Det er sprengt ut noen få m3 i denne mineraliseringen i forbindelse med prøvedriften på Fiskefjord jernmalmforekomst i perioden 1904 - 1907. Grove flak av molybdenglans opptrer spredt i en minst 1 m mektig steiltstående sone (oppover skrenten) i en grovkornig mangeritt (?) med pyroksen (prøve 03 og 04). I kontakten med molybdenmineraliseringen i V er en 3 - 4 m mektig parallell sone med middelskornet gabbro med disseminert til semimassiv magnetkis og noe kobberkis (prøve 01 og 02). |
