Teck’s Red Dog Operations Achieves Zinc Mark Verification

Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) today announced its 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 CEO, 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.”

Michèle Brülhart, 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 multi-metals 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.

To be verified for Copper Mark, operations are assessed and independently verified against 32 responsible production criteria including greenhouse gas emissions, community health and safety, respect for Indigenous rights and business integrity. More information about the Copper Mark verification can be found here.

Teck is one of the world’s largest producers of mined zinc. Red Dog Operations is one of the world's largest zinc mines and the largest critical mineral mine in the USA while Teck’s Trail Operations is one of the world’s largest fully integrated zinc and lead smelting and refining facilities. Teck’s Trail Operations has an extremely low carbon intensity for its product as outlined in this report .

In 2023, Teck’s Trail Operations was the first smelting and refining facility globally to achieve the Zinc Mark verification and Teck’s newly expanded Quebrada Blanca Operations (QB) and Carmen de Andacollo Operations (CdA) were awarded the Copper Mark. In 2022, Teck’s Highland Valley Copper Operations was the first mine in Canada to achieve Copper Mark verification.  

Teck’s commitment to responsible production is underpinned by a comprehensive sustainability strategy, which guides our focus on operating sustainably, ensuring the health and safety of our people, and building strong relationships with communities.
