Teck Resources shares rose Wednesday morning after the company reported strong output in the fourth quarter, topping expectations, and reaffirmed its medium-term guidance.

Shares traded 6.6% higher at 74.02 Canadian dollars ($53.49).

The Canadian diversified mining company produced 134,100 metric tons of copper in the quarter, thanks to a strong performance from its Quebrada Blanca mine in northern Chile. In the prior-year period, production came to 122,100 tons.

According to FactSet, analysts expected a slight decline to 117,300 tons for the period.

The quarter's copper production brought full-year output to 453,500 tons.

Zinc production came to 108,600 tons for the quarter, while refined zinc rose to 68,100 tons, up from 62,000 tons a year earlier.

Teck reaffirmed its 2026 to 2028 production guidance across its operated sites but cut 2026 zinc outlook from its Antamina mine in Peru to 35,000 to 45,000 tons due to an updated mine plan, while leaving its copper guidance unchanged at 95,000 to 105,000 tons.
