The deposit is situated in a wide zone of sericitized and chloritized supracrustals, originally quartz and feldspar rich acid volcanics. The ore zone strikes E-W and the dip varies between 45° and 70° S. The plunge is approximately 45° SW. The hostrock surrounding the are is strongly schistose sericite-quartzite with varying chlorite content. The are zone consists of talc-chlorite schist, usually best developed in the hanging wall.
There are two major are lenses. A and A3. Both are mixed sulphides with contents of gold, silver, copper, zinc, lead and sulphur. In terms of value- zinc is the most important are.
Kristineberg is among the first ores found in the so called Skellefte-district, and also the first one to be confirmed through electrical ore prospecting (geophysics) in 1918. 1930-34 further investigations and 35 the shaft is sunk to 90 m level, decision to start mining -37 and the first ore leaves for Boliden in 1940. Kristineberg was the starting point of the ropeway passing thrugh the district, passing Rakkejaur to Boliden. Today among deepest mines in Sweden with mining at +1100 meters.
