Iron mine closed 1954.

The mine was driven in an ore body standing as a rounded pillar, surrounded by leptite and granite. The ore is a low phosphorous iron ore.
The ore was mined down to 135 m dept and a shaft was sunk to 303 m dept. At the bottom a large amount of ore was found but since it was split into several smaller ore bodies it was not possible to mine it. Several diamond cores were made to search for more ore between 135 m and 303 m, as well as from the bottom level.
