Red Dog Mine, Chukchi Sea

Red Dog Mine, Chukchi Sea

by | Feb 22, 2020

The Red Dog Mine is a zinc and lead mine about 46 miles (74 km) inland from the Chukchi Sea coast and connected by road to an export terminal, 89 miles (144 km) southeast of Point Hope and 62 miles (100 km) northwest of Kotzebue, Alaska. This metal sulfide mine is the second largest producer of zinc in the world and is a major source of revenue for Alaska Native corporations across the state.

In the mid-1950s, a local bush pilot and prospector named Bob Baker noticed red-stained creeks in the area. In 1968, a geologist from the U.S. Geological Survey sampled rocks and stream sediments in the region and named Red Dog Creek after Bob Baker’s dog. In 1975, the U.S. Bureau of Mines conducted a mineral examination of the Red Dog site. Interest in mining these deposits was expressed by both the NANA Regional Corporation Inc. who owns the land, and by the Cominco mining company that later became the Teck mining corporation. Active exploration of the site and adjacent area began in 1975 and the first claims were staked in 1978. In 1980, Cominco Alaska drilled 9 holes that totaled 915 meters to determine the size of the deposit. Geologic mapping was done in the region from 1977 to 1984. In 1986 the State of Alaska agreed to construct a shallow-water port on the Chukchi Sea and a road connecting the port to the mine site. Construction on the port, road, and open-pit mine began in 1987 and the first ore was processed by the mill in late 1989.

The ore from Red Dog is mined year-around and trucked 55 miles (89 km) to a storage facility on the Chukchi Sea coast. 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 ore is shipped to a metallurgical facility in Trail, British Columbia, and to Asia and Europe. The main pit is almost depleted, but in 2010 the mine began extracting ore from an adjacent pit that is expected to last until 2031. Read more here and here. Explore more of Red Dog Mine here:

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2019 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The colour scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
