Thumbs-up for Alaskan mine draws fire
Science Magazine - Edited by Jeffrey BrainardA company seeking to build a controversial gold and copper mine in Alaska won a major victory on 24 July when the U.S. Army Corps of Engineers issued an environmental analysis saying the mine wouldn’t endanger the world’s most productive sockeye salmon fishery. The decision clears the way for the Corps to issue permits needed by promoters of the Pebble Mine, located at the headwaters of two major watersheds that form part of the Bristol Bay salmon runs, just north of the Aleutian Islands.

Environmental and Native Alaskan groups and some salmon scientists blasted the new study, saying it understated risks by focusing on the mine’s small, initial footprint over 20 years of mining rather than its potential impacts if it expands to become one of the world’s largest gold and copper mines, as its promoters hope. Mine backers have said such an expansion would get a closer environmental review later if they pursue it. Scientists have raised concerns that even the smaller mine could have wide impacts, because the resilience of the salmon runs hinges on access to a wide variety of spawning habitats. Environmental groups have vowed to file lawsuits to block the project.
