Rio Tinto Announces it is Withdrawing from Pebble Mine Project in Alaska

Statement from Trillium Asset Management, LLC and Calvert Investments on Rio Tintos withdrawal from the Pebble Mine Project
April 9, 2014: Rio Tinto plc (LON: RIO) 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. In March, Trillium Asset Management (Trillium) and Calvert Investment Management, Inc. (Calvert) specifically requested that Rio Tinto re-examine its participation in the project.
Rio Tinto’s withdrawal also follows Anglo American’s (LON: AAL) withdrawal from the Project in September 2013 and the U.S. Environmental Protection Agency’s February 2014 decision to initiate a Clean Water Act 404(c) review of the project. This most recent development is yet another clear signal that the proposed Pebble Mine is the wrong mine in the wrong place.
The Bristol Bay region of Alaska, where the colossal open pit mine is proposed, 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 and non-natives in the region.
Groups of investors, representing tens of billions of dollars, have, for years, 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 that Rio Tinto reached a similar conclusion after its strategic review, which led to the company’s decision to withdraw from the project.
We will be working with fellow investors in the next few weeks to communicate our ongoing concerns to the EPA as it accepts comments on its Clean Water Act review.
