Ero Copper (TSX: ERO, NYSE: ERO) has reduced its full-year copper production guidance due to the delay of commercial production at the Tucumã operation in Pará, Brazil, following power disruptions in the third quarter.
The company now forecasts copper production of 43,000 to 48,000 tonnes in concentrate, down from its original guidance of 59,000 to 72,000 tonnes.
In the third quarter, the Caraiba operation produced 10,766 tonnes of copper, while the Xavantina operation yielded 31,446 ounces of gold.
Full-year gold production guidance was maintained at the increased range of 60,000 to 65,000.
