Kensington Gold Mine

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 2018, approximately 651,515 tons of ore were mined, with 626,419 tons of ore processed through the mill facility. Approximately 19,317 tons of concentrate were shipped to an off-site refinery producing approximately 113,138 ounces of gold. With the addition of the gravity circuit, total gold production for 2018 is approximately 116,770 ounces. Currently, they employ 367 people.
