| Lottvika er en massiv til semi-massiv jernsulfidsone som kan følges ca. 200 m langs sjøen. Den er synlig i en 4-6 m høy skrent hvor det er gjort mindre arbeider. Koordinatene til forekomstene er angitt hvor det er gjort mest arbeid. Der er det sprengt ut 3 m langt og 0,6 m høyt innhugg/lien stoll i skrenten. Flere 1-20 cm tykke lag/linser med massiv magnetkis som kan følges noen meter finnes i sulfidsonen med total mektighet på opptil 2 m. Magnetkis dominerer, men prøver viser at små mengder sinkblende også finnes. |
