delighted to be able to welcome the former shareholders of NAN as new 
shareholders of Lundin Mining. The combination of Zinkgruvan, NAN's 
production and exploration assets and Lundin Mining's highly prolific 
exploration projects in Norrbotten will, together with the announced 
intended merger with ARCON, serve to create a highly competitive leading 
European base metals producer - and to create significant values for our 
shareholders", comments Mr. Lukas Lundin, Chairman of Lundin Mining.
