The Greens Creek Mine is the 5th largest silver producer in the world. The mine is located about 16 miles (25 km) south of Juneau, Alaska, within the Admiralty Island National Monument.
The deposits at Greens Creek were discovered in 1975 and full production began in 1989. The mine is an underground operation, with surface disposal of tailings onto two 29 acres (120,000 sq m) sites. The mill produces semi-pure Doré bars of silver, gold, zinc, and lead on-site. These are trucked 9 miles (14 km) from the mill complex to a port site on Hawk Inlet for export to smelting and refining facilities.
The mine closed for a few years during the mid-1990s due to low metal prices but currently operates at capacity. It is the largest private employer in the Juneau Borough with 280 workers. Most mine workers commute from Juneau on a high-speed ferry. Historically the mine used diesel generators to supply power, but now a submarine cable transmits 95 percent of the power directly from the Juneau grid. Read more here and here.
