TECK.B Teck Resources Limited

Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) today provided unaudited third quarter 2023 steelmaking coal sales volumes and realized prices.

Our third quarter steelmaking coal sales were 5.2 million tonnes, below our guidance of 5.6 – 6.0 million tonnes due to slower than anticipated supply chain recovery following the impacts of B.C. wildfires and the labour disruption at B.C. ports, and plant challenges. We implemented a plant improvement initiative in the second and third quarter and are seeing improved plant performance in the fourth quarter. The realized steelmaking coal price in the third quarter averaged US$229 per tonne. We expect to report a positive steelmaking coal provisional pricing adjustment of $23 million in the third quarter.

Our third quarter 2023 financial results are scheduled for release on October 24, 2023.
