Boliden's exploration success continues

Boliden today reports further success in exploration at its Kristineberg Mine in Västerbotten, Sweden.

In November Boliden announced the discovery of a zinc-silver rich mineralization at 900 – 1000 m depth in the mine. SEK 60 million has now been approved for the development and preparation for production of the so called K-zinc.

Continued exploration in the same area has revealed a new copper-gold-zinc mineralization (J-zone). The first assay data indicated promising grades.

The new copper-gold-zinc zone is located underneath the Einarsson ores and the K-zinc. The J-zone lies within the existing Exploitation Concessions at Kristineberg. Boliden intends to continue drilling into the J-zone in order to obtain information on geology and the possible extension and continuity of the zone.

Exploration and development of deposits containing copper is strategically important to Boliden and to the supply of concentrate to the smelter at Rönnskär.

Bolidens laboratory at Rönnskär has performed the assays. Randomly selected samples are sent to Chemex in Vancouver for check assay.

The exploration program is conducted by Boliden geologists and is supervised by Mati Sallert, Bolidens Manager of Ore Reserves and Project Evaluation. Mr Sallert is registered as a "Qualified Person" by the Swedish Mining Association.

The Kristineberg Mine has been in production since 1940 and currently has around 150 employees. The ore mined there contains copper, lead, zinc, gold and silver.

More press releases & news

The abnormally high seismic activity in Garpenberg has decreased and mining production at low levels will commence in the second quarter. The first quarter throughput was just under 0.8 Mton instead of the expected slightly over 0.9 Mton at already communicated grades. All inspections are not yet complete but production in the most affected part of the mine is not expected to resume in 2026. Until further notice, Garpenberg's production is therefore estimated to be around 30 percent of the guided capacity of 3.7 Mton per year. For the first quarter of 2026, EBITDA will be negatively affected by approximately SEK -400 million at today's prices and terms.

Boliden has decided to invest in a new hoist system at Garpenberg and an industrial demonstration plant for the production of supplementary cementitious material at Rönnskär. The investments, which amount to SEK 4 billion and SEK 1.5 billion respectively, will strengthen the earnings capacity of both units and lay the foundation for exploiting further future opportunities.
