The mine is situated in the forest immediately east of the Botshaugdalen farm. It comprises a an 2 m wide and 8 m long water-filled shaft that according to the size of the spoil heaps, appear to be 5-10 m deep. The shaft and two small pits 10 m and 20 m northwards is connected with trenches exposing the vein system. The shaft has been driven down along a meter-wide zone trending NE-SW which comprises parallel and interconnected quartz veins (0.1-0.3 m thick) inside a zone of gneissic aplite truncating grey granodioritic orthogneisses at the northern margin of the shaft. At the border between aplite and granodiorite the vein system turns to NNE-SSW and then to NW-SE in the first pit to the north. The wall rocks are commonly only weakly sericite-altered in a 0.1-0.3 m wide zone along the vein contact with the exception of areas, where the host-rocks contain networks of thin quartz veins in pyritic sericite alteration. The main quartz veins contain interstices and vein-parallel fractures filled with pyrite, chalcopyrite and specularite (hematite). Analyses of the ores yield up to 10 g/t Au. |
