Project Description

The Kensington Gold Mine is an underground long hole stoping and drift-and-fill operation using flotation processes to recover gold. The mine is located in southeast Alaska, in the Tongass National Forest between Berners Bay and Lynn Canal, approximately 45 air miles north of Juneau and 35 air miles south of Haines. It is situated on private and U.S. Forest Service lands within the City and Borough of Juneau and access to the mine is by air or sea. The project is operated by Coeur Alaska, Inc. (Coeur), a wholly owned subsidiary of Coeur d'Alene Mines Corporation. The major Kensington Mine facilities include the Kensington underground mine, underground paste backfill plant, surface mill, tailings treatment facility, administrative and camp facilities, generator facilities, water treatment facilities, and marine dock facility. Power is supplied by on-site diesel generators. The mine was originally permitted in 2005, and operates 24-hours a day, 365 days a year. In 2014, approximately 642,249 tons of ore was mined, with 635,961 tons ore processed through the mill facility. Approximately 18,378 tons of concentrate was shipped to an off-site refinery producing approximately 120,469 ounces of gold. As of 2014, Coeur employs approximately 318 people.
