Lundin Mining is a Canadian mining and exploration company with a focus in Europe. The Company is one of the world's leading producers of zinc. The main asset of Lundin Mining is the Zinkgruvan mine, located about 200 kilometers southwest of Stockholm, Sweden. The mine has been producing zinc, lead and silver on a continuous basis since 1857. Zinkgruvan has consistently ranked in the lowest cost quartile among zinc mines in the world. In the beginning of 2005, Lundin Mining acquired the remaining outstanding shares of North Atlantic Natural Resources AB (NAN). NAN's primary asset is the Storliden copper and zinc mine in the Skellefte mining district of northern Sweden, which has been in production since 2002. By acquiring ARCON International Resources P.l.c. of Ireland, Lundin Mining added the Galmoy zinc-lead mine and an extensive exploration acreage in the county of Kilkenny, Ireland to it's existing portfolio. Lundin Mining also holds a large copper/gold exploration project in the prolific Norrbotten mining district in northern Sweden as well as exploration permits covering numerous exploration targets in the historical Skellefte mining district of northern Sweden.
