Pebble Project

History and Location

The Pebble Project is located approximately 200 miles southwest of Anchorage in the Bristol Bay region. The deposit lies entirely within the Lake and Peninsula Borough, approximately 23,782 square miles of land which is home to some 1,500 people in 18 communities.

The area around Pebble was secured by the State of Alaska during the Cook Inlet Land Exchange of 1974 - a three-way land swap involving the federal government, the State and the Cook Inlet Region Inc. (CIRI), an Alaska Native regional corporation. The State of Alaska secured land including what is now Pebble, explicitly for its mineral potential.

Surrounding terrain is characterized by tundra, gently rolling hills and the absence of permafrost. At just 1,000-feet above sea-level and 65 miles from tidewater on Cook Inlet by air, the project setting presents few obstacles to successful mine and infrastructure development.

Alaska is known around the world for its rigorous environmental standards, as well as its healthy fish and wildlife populations. The state currently has five hard rock mines with exemplary performance records and five major development projects, including Pebble.

While enforcing high standards, regulatory oversight in Alaska is also intrinsically stable and predictable. Alaskans strongly support responsible resource development, and have clearly indicated their support for the state's permitting system as the appropriate venue for evaluating projects like Pebble.

Northern Dynasty is confident that Pebble can be developed in an environmentally sound and socially responsible manner, consistent with Alaska and US standards.

2001

  • Northern Dynasty secures agreements to purchase Pebble property

1988 - 1997

  • Cominco (now Teck) explores the property

(1) The IHS Global report is based on a conceptual mine plan using an iteration of the engineering work undertaken by the Pebble Partnership in 2013 and is the only economic impact study available at this time. The IHS report is intended to provide information about general economic effects/contribution of a development at Pebble to Alaska and the United States. The report should not be used to evaluate the Pebble Project’s impact on Northern Dynasty.
