| Det østlige malmdraget (se FI0012 Boris Gleb) er her foldet ned i en isolert synform. Det ble i 1961 boret på en magnetisk anomali rett SØ for Sandnesvatnet, men resultatet var negativt. Malmen har utgående SØ for borområdet, der liggmalm fra det østlige malmdraget (Vakkeråsdraget) danner grensen mellom hornblendegneis og kvartsitt. Mektigheten er mellom 2 og 10 m. Malmareal, Bjørnevannskvalitet: 3200 m2 og Tverrdalskvalitet: 5000 m2. Forekomsten er vurdert å være for liten, for fattig, og ligger for nær bebyggelsen til å være aktuell for drift. |
