About Red Dog

Red Dog Operations is one of the world's largest zinc mines, located about 170 kilometers (105 miles) north of the Arctic Circle in northwest Alaska, near Kotzebue.

In 1982, Red Dog Operations was developed through an innovative operating agreement between the operator Teck and the land-owner NANA, a Regional Alaska Native corporation owned by the Iñupiat of northwest Alaska. The mine and concentrator properties are leased from, and were developed under the agreement with NANA.

Red Dog is an open-pit truck-and-loader operation, using conventional drill and blast mining methods. Concentrates produced at Red Dog are shipped to our metallurgical facilities in Trail, British Columbia, and to customers in Asia and Europe.

The current mine life, based on existing developed deposits, is expected to extend through to 2031.
