Pebble Mine tailings storage facilities

Meeting Pebble Mine's resource needs

The Pebble operations would require a tremendous volume of water. This water would be used for processing ore, slurrying as much as 10.8 billion tons of mine waste from the mill to the waste-storage facilities, and slurrying concentrate along the 86-mile pipeline from the mine to the port. The Pebble Mine will also require considerable power, which will likely drive construction of new power plants at the mine and port sites. The above graphs show the estimated Pebble Mine power usage (MW/yr) as compared to the cities of Anchorage and Fairbanks and estimated water usage (billions gal/yr) as compared to Anchorage and Red Dog Mine, currently the largest mine in Alaska.
