Greens Creek Mine

Project Description


The Greens Creek Mine is an underground cut-and-fill and long hole stoping operation using grinding and flotation processes to recover zinc and lead, and gravity processes to recover silver and gold.

The mine is located in southeast Alaska, in the Tongass National Forest near Hawk Inlet on Admiralty Island National Monument, approximately 18 miles southwest of Juneau, on U.S. Forest Service and private patented land within the City and Borough of Juneau. Access to the mine is by sea, and a 13-mile access road.

The project is operated by Hecla Greens Creek Mining Company (HGCMC). The major Greens Creek Mine facilities include the Greens Creek underground mine, surface mill, dry stack tailings facility, tailings storage facility, water treatment system, wastewater treatment plant, administrative and camp facilities, ferry dock and ship-loading facility. Power is supplied by hydroelectric infrastructure and diesel generators.

The mine started production in 1989, and today operates 24-hours a day, 365 days a year. In 2017, Greens Creek Mine produced approximately 8,351,882 ounces of silver, 50,854 ounces of gold, 52,547 tons of zinc, and 17,996 tons of lead. As of 2017, Hecla Greens Creek Mining Company employed approximately 430 people.
