Investor organizations holding over $170 billion in assets are urging the U.S. Environmental Protection Agency to evaluate the mine waste impacts of the proposed Pebble Mine on Alaska’s Bristol Bay watershed, an ecosystem of international significance. Pebble is a joint project of London-listed Anglo American and Canadian Northern Dynasty, in which Rio Tinto is a major shareholder.
The stakes are high. Southwest Alaska’s Pebble mine site holds the world’s largest undeveloped copper-gold-molybdenum deposit, while Bristol Bay supports the world’s largest remaining wild sockeye salmon runs, which produce roughly half of all the world’s commercial sockeye salmon.
