Teck Resources Limited reported unaudited 2025 production that was generally in line with prior guidance and reaffirmed most of its 2026–2028 outlook for Teck-operated sites. Annual copper production reached 453,500 tonnes, supported by strong fourth quarter performance, including 55,400 tonnes of copper from Quebrada Blanca as that operation continued to work toward steady-state conditions. Copper sales in the fourth quarter lagged production due to weather-related shipment delays at Quebrada Blanca, shifting some volumes into early 2026.
Annual zinc in concentrate production was 565,000 tonnes, at the higher end of guidance, with Red Dog contributing 462,700 tonnes and Antamina 102,300 tonnes. Refined zinc production was 229,900 tonnes, also at the top of its guidance range, reflecting a focus on processing higher-margin residues. Teck expects to record $295 million of positive settlement pricing adjustments in the fourth quarter due to higher base metal prices.
The company maintained its previously disclosed production and net cash unit cost guidance for 2026–2028 across its operated assets, with one notable change: 2026 zinc in concentrate production guidance for Antamina was reduced to 35,000–45,000 tonnes from 55,000–65,000 tonnes, based on an updated mine plan. Antamina’s 2026 copper production guidance of 95,000–105,000 tonnes remained unchanged.
