| Malmen ligger NV for Ørnevatn, i flankene av en kompleks synformstruktur som strekker seg over til Ørnevatnmalmen (FI0261). Malmen er hovedsaklig konsentrert i NV, i to adskilte malmkropper. Det er mulig at malmkonsentrasjonen strekker seg mot dypet mot SØ. Malmen er en god liggmalm av samme type som på Kjellmannsåsen og Ørnevatn, med gehalt 25 - 32 % Fe magn. Malmareal: 8500 m2. |
