TRAIL OPERATIONS IS FIRST SMELTING & REFINING FACILITY GLOBALLY TO ACHIEVE ZINC MARK VERIFICATION

Teck Resources Ltd.'s Trail operations has been awarded the Zinc Mark.

Teck's Trail operations is the first stand-alone zinc processing site globally to receive the Zinc Mark. This was achieved using the Copper Mark's multimetals approach and assurance framework. To achieve the Zinc Mark, Teck's Trail operations was assessed and independently verified against 32 responsible production criteria including greenhouse gas emissions, community health and safety, respect for indigenous rights, and business integrity.

"Zinc has a crucial role to play in global efforts to decarbonize as its primary use in galvanizing steel extends the life of essential infrastructure and clean tech like renewable power and electric vehicles," said Jonathan Price, chief executive officer, Teck. "It is important to produce zinc sustainably and responsibly, and we're proud that Trail operations has been awarded the Zinc Mark."

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 and demonstrate the industry commitment to the United Nations Sustainable Development Goals.

"We're delighted that Teck has become the first stand-alone zinc processing site to receive the Zinc Mark. The Copper Mark's multimetals approach was developed with the ambition of making more responsibly sourced zinc, molybdenum and nickel available to society. Today's award testifies to Teck's commitment to this vision. We are looking forward to continuing our collaboration with Teck to promote sustainable and responsible practices across the zinc value chain," said Michele Brulhart, executive director of the Copper Mark.

"Since its inception less than six months ago the Zinc Mark has realized clear routes for industry to demonstrate responsibility under a single ESG framework. We applaud Teck for achieving the Zinc Mark, which helps enable responsible sourcing of raw materials used in the green transition," said Andrew Green, International Zinc Association executive director.

Teck's approach to operating responsibly is underpinned by a long-term sustainability strategy that sets the company's goals in the areas of Health and Safety, Climate Change, Responsible Production, Our People, Water, Tailings Management, Communities and Indigenous Peoples, and Biodiversity and Reclamation.

Teck is one of the world's largest producers of mined zinc, and 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 a recent report. Teck's Red Dog operations is one of the world's largest zinc mines and the largest critical mineral operation in the United States.

This verification by Trail operations follows Teck's Highland Valley Copper operations achieving Canada's First Copper Mark verification in 2022.

About the Copper Mark

The Copper Mark is an assurance framework to promote responsible practices and demonstrate the transition minerals industry's contribution to the United Nations Sustainable Development Goals. The Copper Mark uses a rigorous site-level assessment process to independently verify whether individual copper, nickel, zinc and/or molybdenum producing sites have responsible production practices. Over 25 per cent of globally mined copper is currently produced by Copper Mark-assured sites.

The Copper Mark was built on a genuine commitment of the copper industry to responsible production, and the framework has since expanded to allow participation by nickel, zinc and molybdenum producers. The Copper Mark framework involves a robust three-year re-evaluation process at site-level for participants. Participants commit to continual improvement, building the management systems necessary to ensure continuing legal compliance.
