Information regarding potential upcoming dispute

Boliden has been informed that a number of British and Scottish companies in the
listed Travis Perkins Group have sued Boliden in an English court. The claim was
filed with the Competition Appeal Tribunal in London and is in the process of
being served on Boliden.

The information that Boliden has been provided with to date, contains a number
of uncertainties and unsubstantiated allegations. As a result, it is at present
not possible for Boliden to take any position in respect to the claim or to
estimate what potential exposure, if any, it entails for Boliden.

Background
The basis for the claim is that Travis Perkins allegedly suffered financial loss
as a result of the higher gross prices which Travis Perkins was charged due to
the sanitary copper tubing cartel that Boliden and seven other companies
participated in from June 1988 to March 2001 and later were fined for by the
European Commission in 2004. The Commission's decision led, among other things
to Boliden, following a judgment by the General Court in Luxembourg in May 2010
upholding the decision, paying MSEK 367 in fines and interest.
