The Link - Spring 2024

Teck Resources Ltd.’s Red Dog Operations in Northwest Alaska is the world’s first zinc mine to be awarded the Zinc Mark, a certification that the facility meets high environmental, social and governance standards. Accounting for more than 4% of global zinc production — along with lead, silver, and germanium byproducts — Red Dog is the largest critical minerals mine in the United States. “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 Teck Resources President and CEO Jonathan Price. Now, the critical metal produced at Red Dog will bear the Zinc Mark, an extension of the Copper Mark framework established by the International Copper Association in 2019 as an independent entity to promote responsible mining practices and demonstrate the sector’s efforts to uphold the United Nations Sustainable Development Goals. Copper Mark-assured sites currently account for 25 percent of the copper mined globally. This includes Teck’s Highland Valley Copper Operations in BC, which was the first mine in Canada to be awarded the Copper Mark. This sustainability certification was expanded to include Zinc Mark, Molybdenum Mark, and Nickel Mark. To be certified with any of these marks, operations are assessed and independently verified against 32 ESG criteria, including greenhouse gas emissions, community health and safety, respect for Indigenous rights, and business integrity. — North of 60 Mining News www.AlaskaAlliance.com 2024 Meet Alaska Conference & Trade Show 59 Red Dog honored with first Zinc Mark Serving all of Alaska since 1958 TEMSCO Helicopters, Inc PO Box 5057 Ketchikan, Alaska 99901 Phone 907-225-5141 • fax 907-225-2340 • www.TemscoAir.com HELICOPTERS, INC.
