About Red Dog
Red Dog Operations is both the largest critical minerals mine in the United States and one of the largest zinc mines in the world. In 1982, Red Dog was developed through a partnership between Teck and the land-owner NANA, an Alaska Native corporation owned by the Iñupiat of northwest Alaska. The partnership between Teck and NANA ensures real benefits for the local Iñupiat community, while recognizing there is still more to do as we advance our commitment to sustainable practices and meaningful engagement.
