The 1998 dam breach at the Los Frailes mine in Spain
In April 1998, a dam breach accident occurred in the tailings pond at the Los Frailes mine in Spain, which was then owned by Boliden's subsidiary, Boliden Apirsa S.L. ("Apirsa"). Large and successful remediation efforts were carried out in the same year, however, legal disputes regarding the costs of these efforts remain.

Deliveries of smelting residues to Chile during the mid 1980s
Between 1984 and 1985, Boliden delivered a total of approximately 20,000 tonnes of metallic residues from the Rönnskär smelter to the Chilean company, PROMEL, in the city of Arica. We wish to clarify Boliden's role regarding the deliveries and our position regarding the damages that may be attributable to the deliveries.
