Det er utsprengt 3-4 m3 i en skrent ved sjøkanten. Magnetitt- mineraliseringen er knyttet til en liten skarnkropp i båndet diorittisk gneis. Skarnkroppen har uregelmessig form og er diskordant i forhold til båndingen i omliggende gneis. Båndingen er delvis utvisket av skarndannelsen, men kan følges gjennom skarnet. Skarnmineralene er epidot, granat, pyroksen, kalkspat, hydrotermalkvarts og mikroklin. Det er uregelmessig magnetitt-mineralisering, fra sterkt impregnerte bånd , årer og uregelmessig disseminasjon (prøve 02), til svak disseminasjon (03 og 04). Uregelmessige årer og ansamlinger av kvarts og mikroklin har ofte magnetitt-anrikning langs kontaktene (01). Skarnlinsa er 3,5 m mektig ved sjøkanten og kiler ut etter få meter til noen få dm.
