Teck Reports Elkview Plant Outage

VANCOUVER, Sept. 20, 2022 - Teck Resources Ltd. (TSX: TECK.A and TECK.B, NYSE: TECK) ("Teck") announced today that there has been a structural failure of the plant feed conveyor belt at its Elkview steelmaking coal operation in the Elk Valley of British Columbia. Initial estimates are that production at Elkview Operations will be interrupted for 1-2 months as repairs are implemented. Elkview will reschedule planned plant maintenance to take advantage of plant downtime and mine operations will focus on pre-stripping during the outage. Assuming a two-month suspension of plant operations, Teck expects the impact on 2022 steelmaking coal production will be in the range of 1.5 million tonnes.

When also factoring in the impact of the recent labour action at Westshore Terminals, Teck's third quarter steelmaking coal sales are now expected to be between 5.5 - 5.9 million tonnes versus our previously announced guidance range of 5.8 - 6.2 million tonnes.
