Red Dog Mine

Project Description

The Red Dog Mine is an open pit, truck-and-loader operation using grinding and flotation processes to recover zinc and lead. The mine is located in northwestern Alaska, in the De Long Mountains of the Western Brooks Range, approximately 82 miles north of Kotzebue and 46 miles inland from the coast of the Chukchi Sea, on land owned by NANA Regional Corporation, Inc. (NANA). Access to the mine is by air. The project is a partnership between NANA and Teck Alaska Incorporated (Teck) (the operator). The major Red Dog Mine facilities include the Red Dog Main pit, Aqqaluk pit, mill, tailings storage facility, main waste stockpile, fresh water storage reservoir, water management systems, airstrip and Personnel Accommodations Complex (PAC). Power is supplied by on-site diesel generators. The mine has been in operation since 1989, and operates 24-hours a day, 365 days a year. In 2015 Red Dog mined 3,861,950 tonnes ore, milled 4,026,082 tonnes, and produced 1,013,607 tonnes zinc concentrate and 212,123 tonnes lead concentrate. All concentrates are exported to world markets via the DeLong Mountain Transportation System that connects the mine to port facilities on the Chukchi Sea. As of 2015, Teck employs over 630 people. The majority of Red Dog employees are NANA Shareholders.
