Greens Creek Mine
Project Description
The Greens Creek Mine is an underground cut-and-fill and long-hole stoping operation using flotation and gravity processes to recover silver, gold, lead, and zinc.
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 mine facilities include the underground mine, surface mill, dry stack tailings storage facility, wastewater treatment plant, administrative and camp facilities, ferry dock, and ship-loading facility. Power is supplied by connection to the local hydroelectric-powered utility with diesel generators as a backup.
The mine started production in 1989 and today operates 24-hours a day, 365 days a year. In 2023, HGCMC produced approximately 9.7 million ounces of silver, 60,900 ounces of gold, 51,500 tons of zinc, and 19,600 tons of lead. As of 2024, HGCMC employed approximately 512 people.
