I en veiskjæring på sydsiden av Vornesveien ses en liten vasskismineralisering. Man finner lokaliteten ved å gå ca. 100 m mot Våge fra Steinsvågstjørna. Mineraliseringen ligger på nordsiden av Håvardshaugen. Der ses ett, muligvis to sulfidlag av 10-20 cm's tykkelse som adskilles av forskifret basalt. Over det øverste sulfidlaget ses en ca. 10 cm tykk jernhatt. Ellers er begge sulfidlagene forvitrete, og den ytterste skorpen består av en porøs chertaktig masse. I det øverste sulfidlaget er det et sted en kraftig deformasjon som kommer til uttrykk ved at lamineringen er foldet i loddrett stilling. Mineraliseringen er ikke omtalt i litteraturen.
