Excerpt: Pebble Mine is the common name of an advanced mineral exploration project investigating a very large porphyry copper, gold, and molybdenum mineral deposit in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. The proposal to mine the ore deposit, using large-scale operations and infrastructure, is controversial. Proponents argue that the mine will create jobs, provide tax revenue to the state of Alaska, and reduce American dependence on foreign sources of raw materials. Opponents argue that the mine would adversely affect the entire Bristol Bay watershed; and that the possible consequences to fish populations, when mining effluents escape planned containments, are simply too great to risk. Much of this debate concerns the tentative plan to impound large amounts of water, waste rock, and mine tailings behind several earthen dams at the mine site. The exact nature and scope of proposed mining activities at Pebble are yet to be finalized - but the general outline of the plan is known. A contiguous body of ore is known as Pebble West where mineralization locally extends to the surface, and as Pebble East where it is a deeply buried (off to the east) root of the deposit. Pebble West would probably be mined as...
