TECK'S RED DOG OPERATIONS ACHIEVES ZINC MARK VERIFICATION

Teck Resources Ltd.'s Red Dog operations, the largest critical mineral mine in the United States, has been awarded the Zinc Mark in recognition of environmentally and socially responsible production practices.

"Zinc plays an important role in enabling a low-carbon future and our people are focused every day on responsibly producing this critical mineral that the world needs," said Jonathan Price, president and chief executive officer, Teck. "With Red Dog being awarded the Zinc Mark, all of Teck's managed base metals operations are now verified and recognized for strong environmental and social performance, illustrating our focus on responsible production for the benefit of our customers, and for the environment and people where we operate."

Michele Brulhart, executive director of the Copper Mark, said: "Teck's Red Dog operation is the first mining site to receive the stand-alone Zinc Mark. We are excited to see the standard applied to other metals operations, and congratulate Teck on the initiative and Red Dog on its achievement."

The Copper Mark multimetals approach includes the Zinc Mark as well as Molybdenum Mark and Nickel Mark. Producers of these metals are able to use the Copper Mark assurance framework to achieve their respective "mark." The Copper Mark assurance framework aims to promote responsible production practices along the value chains of the covered minerals.
