Ottar Jøsang discovered this magnesite/serpentine deposit in 1956 according to his own notes.

Mentioned in Berget (2011). It's located according to Jøsang (1966:93) about 300m SSE of Butjern.

I have not been able to find the exact location of this quarry, and I am not even sure that this is correct Amundrud farm (Ronald Werner, 2021).
