Boliden Profit Jumps 77% as Tight Copper and Zinc Supply Lift Metal Prices

Swedish mining group Boliden reported on Thursday that its third-quarter adjusted operating profit rose roughly 77 percent from a year earlier, as higher copper and zinc prices outweighed operational disruptions and rising costs. The company said operating profit excluding the revaluation of process inventory climbed to about 4.90 billion crowns, equivalent to $494.4 million, up from 2.75 billion crowns in the same quarter last year.

The result reflects a market in which supply constraints have driven copper and zinc prices higher, lifting profitability at Boliden's mines even as lower treatment charges weighed on its smelting business. The company is Europe's third-largest zinc and copper producer and is also active in metal casting, refining and recycling, producing gold, silver and lead alongside its main metals. The chief executive said in a statement that there is a growing consensus that the copper price has a new floor.

Smelting and mine performance

Smelter operating profit excluding inventory revaluation more than doubled to 1.48 billion crowns, as higher metal and sulphuric-acid prices offset lower processing fees. Earlier this year, problems with a new roaster slowed expansion at one of Boliden's smelters, but the company said performance improved toward the end of the quarter, supporting expectations for a faster ramp-up.

At the company's flagship Aitik mine, Boliden cut its full-year copper-grade guidance after more waste rock was mixed with ore, although it raised the site's ore-processing target to 42 million tonnes. The company also maintained its target for the Garpenberg operation to process 1.5 million tonnes of ore. Zinc and silver production at Garpenberg was disrupted by an earthquake in March, though the chief executive said recovery remained on track.

Zinc prices have also surged on tight supply, reaching a four-year high in September as inventories and mined-material availability remained constrained. That backdrop has supported margins across the copper and zinc mining sector, even as individual operations deal with geological and technical setbacks. Higher metal prices and sulfuric-acid prices have been the main counterweights to weaker processing fees at the smelting end of the business.

What it means for workers and skills

For the people who run mines, smelters and processing plants, the quarter points to steady demand for skills in ore processing, metallurgy and plant maintenance. Higher throughput targets at Aitik and Garpenberg depend on engineers and operators who can manage grade control, equipment reliability and commissioning schedules. Smelter ramp-ups similarly rely on process and maintenance teams able to bring new equipment up to full performance after delays.

The results also underline how swings in treatment charges and metal prices can shift the balance between mining and smelting operations within a single company. Roles tied to cost control, energy use and furnace performance tend to come under closer scrutiny when processing fees fall, while mining teams face pressure to protect ore quality and volumes when grades decline. Both pressures shape hiring and training priorities as operators plan the year ahead.

What to watch next

Boliden kept its 2026 capital-expenditure forecast at 15.5 billion crowns, a signal that project spending across its sites is expected to continue. Investors and industry analysts will be watching whether the smelter ramp-up holds through the fourth quarter, whether Aitik can recover its copper-grade guidance, and how far copper and zinc prices stay elevated as supply remains constrained. The company's ability to lift output without adding safety or reliability risk will be a central test.
