Update regarding stopped production at the Garpenberg mine

18 Mar 2026 07:25 CET

In connection with the increase in seismic activity to abnormal levels in the
Garpenberg mine on Saturday evening, March 14, the mine was evacuated and mine
production was halted. Production in the concentrator continued until Sunday,
after which this production was also stopped for planning reasons. The seismic
activity has since decreased and initial inspections of the mine began on
Wednesday, March 18. Production in the mine will be resumed gradually after the
inspection of infrastructure and mining positions has been completed. However,
the timing of resumed production and the rate of ramp up cannot be determined at
this time. The overall impact on Boliden's results can only be estimated once
the inspection of the mine has been completed and the best way to resume
production has been identified.
