Pebble Mine: Tailings Dam Failures

The technical literature fails to show an example of any similar metal-mine tailings impoundment that has not released toxic contaminants into the environment over the long-term via chronic seepage – especially following site closure.

Pebble Mine Report: Overview

In 2012 Wild Salmon Center and Trout Unlimited produced a report examining the proposed Pebble Mine and its impacts on the wild salmon fishery of Bristol Bay, Alaska. This report describes significant ecological, economic, and cultural concerns raised by proposed development of the Pebble copper, gold, and molybdenum deposit in the headwaters of the Bristol Bay basin, which is home to North America’s most abundant wild salmon fishery and the world’s largest sockeye salmon run.
