Production Disturbances at Boliden Aitik

Regulatory News:

During the second quarter, the production in Aitik is lower due to an ore mix that is causing low recoveries and process disturbances in the concentrator. The recovery of copper is expected to stay on the same level as in the first quarter and the milled volume is expected to be negatively affected with around one million tonnes during the second quarter.

The production plan for milled tonnage for the whole year of 2015 has been adjusted to 39 Mtonnes.
