Large portions of Boliden's Garpenberg mine in Sweden will remain closed throughout 2026 following a period of abnormally high seismic activity, according to a company press release. The mining company reports that seismic risks have now decreased, allowing some production to potentially resume during the second quarter of this year. However, significant sections of the underground mine will stay shut down for the remainder of 2026.
The events at the Garpenberg mine are expected to result in an economic loss of approximately 400 million Swedish kronor (around $38 million). Underground work at the mine is estimated to restart in the second quarter following the recent abnormal seismic activity. According to Boliden, the seismic activity in the Garpenberg mine has decreased, though the extended closure reflects ongoing safety assessments.
