The Red Dog Mine is a zinc and lead mine in northern Alaska, located about 80 miles north of Kotzebue in the Northwest Arctic Borough. This metal sulfide mine is the second-largest producer of zinc in the world, and is a major source of revenue for native corporations across the state. Ore is mined year-around and trucked 55 miles to a port on the Chukchi Sea where it is stored for shipment to a metallurgical facility in Trail, British Columbia. Shipments can only be made during four ice-free months, and because of the shallow water, the ore must be lightered to ships with small barges. The main pit is almost out of ore, but in 2010 the mine began extracting ore from an adjacent pit, expected to last until 2031. Read more here and here.
