Gamle Utsjøen mine was recently rediscovered by prospector Wilhelm Tveter who detected the entrance to a mine below the present water level in a small bay on the eastern shore of Lake Utsjøen. This is possibly the site where a 1-2 m wide nearly massive vein of sulphides was reported to have been found in 1787, and which according to old analyses cited by Bradt (1790) contained 255-320 g/t Au. However, all later attempts to find this deposit which was the most gold-rich in the whole Eidsvoll district, has failed. Several explanations for this have been given as discussed by Foslie (1924). But one reason could be that mine became flooded when the Lake Utsjøen dam was built in the 19ths century in order to float timber down the small stream during spring. The registered Utsjøen mine (AK0016) to the south is worked along a quartz vein poor in sulphides. The Gamle Utsjøen mine in the extension of a N-S trending system of milky quartz veins which is exposed in the hillside between Utsjøbråten and Utsjøen, and east of the dirt road on the eastern side of the lake. However, these 1-2 m thick veins contain only minor pyrite and chalcopyrite.
