A small abandoned, now waterfilled mine.
Contact metamorphic sulfide mineralization that occurs occurs in association with a dolerite (diabase) vein.
Marked as locality "F" in Stensrud (2004). It is probably identical with the Co-bearing arsenopyrite locality near Kroksæter of Vogt (1884, p. 288), also mentioned by Goldschmidt (1911, p. 263).
