Trillium / Calvert Statement on Anglo American's Withdrawal from Pebble Mine Project

September 18, 2013 // BOSTON, MA: Anglo American plc (LON: AAL) has announced that it is withdrawing from the proposed Pebble Mine Project in Bristol Bay, Alaska. This action, which casts a cloud of deep uncertainty over the project’s future, follows years of widespread opposition to the proposed open pit mine from Native Alaskans, sport and commercial fishing groups, environmental organizations, and retail grocers, along with other businesses and investors.

Anglo American’s withdrawal is a defining moment in this long running controversy which highlights the unique natural resource that is Bristol Bay. It is the home of the largest wild sockeye salmon fishery in the world, which is sustainably managed and central to the life of the Alaska Natives in the region.

Groups of investors, representing tens of billions of dollars, have expressed deep concern about the proposed mine. In letters to the Environmental Protection Agency in 2011, 2012 and 2013 investors shared their concerns about the Bristol Bay ecosystem, responsible mineral development, sustainable fishery management, Alaska Native culture, and the associated risks.

Trillium, Calvert and other concerned investors believe that this controversy serves as an important example of how environmental, social, government policy and financial risk factors must be addressed in an integrated manner.

We believe Anglo American reached a similar conclusion after its review of the risk/return profile of all projects currently in its pipeline, which led to its decision to withdraw from the project.

Because it is currently unclear whether remaining — or other — mining interests will pursue this large scale mine in any significant way, and because Bristol Bay is a vitally important natural resource, we wish to take this opportunity to, once again, urge the EPA to move forward with its science based review, the 404(c) process, and provide the Bristol Bay region with the protections it needs from large scale mining.

We will be working with fellow investors in the next few weeks to communicate our ongoing concerns to the EPA and other interested parties.
