Metso Minerals will supply a grinding system for a new concentrator at
Boliden's Aitik mine in Gällivare, Northern Sweden. The new concentrator, with
the grinding circuit, is scheduled to start operation in 2010. The value of the
equipment order is approximately EUR 39 million. 

Metso's order comprises two AG (autogenous) mills and two pebble mills,
complemented by engineering, erection and start-up services. Metso has also

annum. The Aitik mine is one of Europe's largest producers of copper, and also
