Teck’s Quebrada Blanca and Carmen de Andacollo Operations Achieve The Copper Mark Verification

Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) today announced its newly expanded Quebrada Blanca Operations (QB) and Carmen de Andacollo Operations (CdA) have been awarded the Copper Mark in recognition of environmentally and socially responsible production practices.

“Copper is an essential metal for the transition to a low-carbon economy and our new Quebrada Blanca operation, as well as our Carmen de Andacollo operation, are contributing to helping sustainably meet growing demand,” said Jonathan Price, President and CEO, Teck. “Being awarded the Copper Mark demonstrates our operations’ commitment to responsible copper production, both for our customers and for the environment and people where we operate.”

“We are pleased to welcome Quebrada Blanca and Carmen de Andacollo among the growing number of sites that have received the Copper Mark,” said Michèle Brülhart, Executive Director of the Copper Mark. “Teck’s operations are a great example of our multi-metal approach, having achieved the Copper Mark, the Zinc Mark and the Molybdenum Mark. We are grateful for Teck’s commitment to the Copper Mark assurance framework and look forward to continuing our partnership on the responsible production of key metals supporting the clean energy transition.”

The newly expanded QB Operation is currently ramping up to full production, which will double Teck’s annual consolidated copper production.

In 2022, Teck’s Highland Valley Copper Operations was the first mine in Canada to achieve Copper Mark verification. In 2023, Teck’s Trail Operations was the first smelting and refining facility globally to achieve the Zinc Mark verification.

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’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.
