Garpenberg may be among the world?s
oldest mines, having started mining in
1200, but by no means can the mine?s
current style be considered conservative. The
mine, which lies just 180 km northwest of
Stockholm, is very comfortable as a technology
leader using some very cutting edge ideas in
underground mine mechanisation.
Milled tonnage production levels reached a
record high and metal production levels for
zinc, lead and silver were high during 2007.
Mine life took a major advance in 1972 when
Garpenberg North went into production.
Another very significant milestone came in
1998 with the discovery of the Lappberget
orebody. Garpenberg North is about 3 km
north of the main shaft system and Lappberget
is only about 200 m east of the main drive
between Garpenberg and Garpenberg north.
The older Garpenberg north mine is now closed but the Garpenberg expansion mine is thriving:
