Teck Reports Resumption of Production at Trail Operations

VANCOUVER, Aug. 13, 2021 - Teck Resources Ltd. (TSX: TECK.A and TECK.B, NYSE: TECK) ("Teck") announced today that the oxygen plant at Trail has been restarted following an improvement in air quality that had been affected by smoke from wildfires in southwestern British Columbia. Operations at the Trail metallurgical facility are ramping back up to full capacity.

However, while production has resumed there remains a risk of further smoke from wildfires and additional outages of the oxygen plant as long as the fire season continues. Regional air quality conditions are being actively monitored and Trail Operations has response plans in place to protect employee safety. Guidance will be updated if necessary after fire risks subside.
