what happened

High acid prices keep weighing on Capstone Copper and may cut annual output more than the market anticipates, Market Talk reports, citing UBS. According to the bank, the company is cutting heap production at Mantoverde to protect its margins as cathode volumes shrink.

UBS lowered its FY27 production forecast by 15,000 metric tons to 209,000 tons, well below the 227,000-ton consensus compiled by Visible Alpha. The bank keeps a buy rating and says acid prices improving could create upside.

The shares fell 4.2% to A$11.34.

why it matters

For the copper market this is mainly a signal about one producer's cost pressure: higher reagent costs can curb leach output and squeeze revenue at current metal prices. The effect is limited to a single company.
