Zinkgruvan is a long-running underground zinc-lead-copper-silver operation in south-central Sweden. Boliden acquired the mine in April 2025 through its wholly owned Zinkgruvan Mining AB subsidiary. Separate zinc-lead and copper ores are treated through crushing, autogenous grinding, flotation and concentrate-dewatering circuits, with paste backfill used underground. Wheaton does not hold an equity interest in the mine but is entitled to 100% of life-of-mine payable silver production under its streaming agreement. At December 31, 2025, Boliden reported resources exclusive of reserves under PERC 2021.
