The NGU has registered a copper mine at the confirmed coordinates:
58.7449130N,9.0594370E.
These coordinates seem to be inaccurate. At the altitude map there is nothing visible that might suggest the presense of an adit. These coordinates are used in Mindat. Needs to be confirmed by visit in the field.
The NGU reports that there is a 33 m long adit.
The deposit was discovered in 1880 and was prospected in 1901 and 1903.
The ore was found in a slightly sulphide mineralised pegmatite hosted in a biotite gneiss. Pyrite and chalcopyrite were the main ore minerals.
The vein has a width of up til 1.4 m and can be followed over a length of 12 m into the mine.
