New details emerge on Garpenberg mine shaft expansion amid seismic issues

Boliden plans a new hoisting shaft at its Garpenberg mine to boost production to 4.5 million tons annually, following a weekend collapse that injured workers and ongoing high seismic activity halting underground operations. The investment builds on earlier announcements amid disruptions.

A collapse over the weekend at Boliden's Garpenberg mine in Hedemora injured several people, followed by high seismic activity that halted all underground work and led to evacuations. Despite these challenges, the company is pressing ahead with expansion plans, including a new hoisting shaft near a mineral-rich area to transport ore to the surface. As previously reported, Boliden is investing four billion kronor in the project to secure the mine's long-term future. The Garpenberg mine produces complex ore containing zinc, lead, silver, copper, and gold. The shaft will support annual production of 4.5 million tons, for which Boliden has environmental permits—though the decision faces appeals. 'It is a future investment for Garpenberg,' site manager Joanna Lindahl told reporters.
