  · Revenues totalled SEK 10,407 million (8,550)
  · The operating profit totalled SEK 1,205 million (265)

Improved prices and terms affected by strong USD

  · The effect of a stronger USD and improved smelting terms outweighed the
impact of lower metal prices.
  · Several minor disruptions to Smelters’ processes resulted in lower feed
compared to preceding quarter’s very strong production.
  · Increased mined production and improved recovery levels at Garpenberg.
  · Production levels fell at Aitik due to winter conditions and maintenance
work.
  · Appeal regarding diesel tax at Aitik was rejected. Boliden continues to
pursue appeals.
