The concerns of many fishing and sportsmen’s groups, environmentalists and local Alaskans have risen over the proposed Pebble open-pit copper/gold mine in southwest Alaska. Here I have superimposed an image of the mine footprint over Washington DC, using Google Earth Pro, to demonstrate the size of the proposed open-pit mine and the tailings and wasterock storage impoundments that we’ve calculated would be necessary to accommodate this mining operation.

We estimate this huge mine will produce 13.5 billion cubic yards of liquid slurry and wasterock. All of the waste must be eternally confined in a seismically activearea that will likely experience major earthquakes. Spills, leakage or any other damage to the dams could negatively affect Alaska’s $5 billion BristolBay fishing industry as well as tourism.
