Three small prospects has been worked east of Fuglavatnet. This locality has the richest mineralization, and is therefore considered the main prospect, where a 1x1m pit has been dug in a 4x5m outcrop. The dump contains an estimated 8m3 rock. Ore occurs throughout the outcroup as dissiminated grains in quartz rich sections a schistose biotite-(amphibole)- quartz gneiss. The richest sulphide mineralization is found associated with thin quartz veins.
