Pebble to challenge borough ordinance in Alaska Superior Court

State of Alaska: 'If enacted, the initiative would be preempted by state law'

VANCOUVER, Oct. 18, 2011 /CNW/ - By a narrow 280 - 246 (53 - 47%) margin, voters in Southwest Alaska's Lake & Peninsula Borough have supported a ballot measure that, if upheld by the courts, would restrict future development that affects more than one square mile of land within the 31,000 square mile borough. The Pebble Limited Partnership (the 'Pebble Partnership' or 'PLP') and the State of Alaska view the initiative sponsored by anti-Pebble activists as unconstitutional and unenforceable because it seeks to restrict development of state-owned resources on state lands through a municipal ordinance, and will challenge it in Alaska's Superior Court.

'Given the ballot measure's misleading language, in particular its seeming focus on protecting salmon, it's not surprising that it was supported by a slim majority of Lake & Peninsula Borough voters,' said Ron Thiessen, President & CEO of Northern Dynasty Minerals Ltd. ('Northern Dynasty')

'What's most important is that the rule of law in Alaska and the United States is clear and reliable, such that this unconstitutional attempt by narrow self-interests to restrict economic development in a region the size of South Carolina will not stand. We believe the State of Alaska's constitutional obligation to manage natural resources on its land for the benefit of all Alaskans will ultimately be acknowledged by the courts.'

On November 7, 2011, the Alaska Superior Court will begin proceedings to consider the constitutionality of the Lake & Peninsula Borough ordinance. In addition to PLP and the State of Alaska, the initiative is opposed by a broad spectrum of Alaska interests, including a group of four Alaska Native village corporations representing seven Lake & Peninsula Borough communities whose private land holdings would be affected by the ordinance. It is also opposed by the Resource Development Council for Alaska, the Alaska State Chamber of Commerce, the Alaska Miners Association, Council of Alaska Producers, the Alaska Oil and Gas Association, Alaska Industry Support Alliance, among others.

In a previous legal filing with Alaska's Supreme Court, the State of Alaska stated that 'the initiative would enact an ordinance that is unenforceable as a matter of law…' and 'will inevitably conflict with, and be preempted by, state law.' The state's legal brief also notes: 'The Alaska Constitution provides that the state has the policy of encouraging the development of resources by making them available for maximum use consistent with the public interest.'

Thiessen said the Pebble Partnership will continue to invest in the State of Alaska with the goal of finalizing a Prefeasibility Study for the Pebble Project and initiating federal and state permitting under the National Environmental Policy Act (NEPA) in late 2012. He said PLP's legal challenge of the borough ordinance will advance in parallel with efforts to design an environmentally sound and socially responsible project that co-exists with clean water, healthy fisheries and traditional ways of life in Southwest Alaska.

'The Pebble Project has the potential to create substantial economic and social benefits for the people of Southwest Alaska for decades to come, in a way that enhances commercial and subsistence fisheries and ensures the long-term sustainability of Alaska Native culture,' he said. 'Pebble simply has too much potential for the region and the state to allow special interests to forestall its development before an optimized mine plan is proposed for the consideration of federal and state regulators and the people of Alaska.'

About the Pebble Project

The Pebble Project is an initiative of the Pebble Partnership to responsibly develop a globally significant copper, gold and molybdenum deposit in southwest Alaska into a modern, long-life mine. The project is located 200 miles southwest of Anchorage on state land designated through two public land use planning exercises for mineral exploration and development. It is situated approximately 1,000 feet above sea-level, 65 miles from tidewater on Cook Inlet and presents favourable conditions for successful mine site and infrastructure development.

The Pebble Project consists of the Pebble deposit, surrounding mineral claims and a stream of financing provided by Northern Dynasty's project partner Anglo American US(Pebble) LLC. The Pebble Partnership was established in July 2007 as a 50:50 partnership between a wholly-owned affiliate of Northern Dynasty and a wholly-owned subsidiary of Anglo American plc. Both Northern Dynasty and Anglo American have equal rights of management, operatorship and control in the Pebble Partnership.

Under the terms of the Pebble Limited Partnership Agreement, Anglo American is required to elect to commit $1.5 billion in staged investments in order to retain its 50% interest in the Pebble Project. Funds provided by Anglo American are currently being invested in comprehensive exploration, engineering, environmental and socioeconomic programs toward the future development of the Pebble Project.

Forward Looking Information and other Cautionary Factors

This release includes certain statements that may be deemed 'forward-looking statements'. All statements in this release, other than statements of historical facts, especially those that address estimated resource quantities, grades and contained metals, are forward-looking statements because they are generally made on the basis of estimation and extrapolation from a limited number of drill holes and metallurgical studies. Although diamond drill hole core provides valuable information about the size, shape and geology of an exploration project, there will always remain a significant degree of uncertainty in connection with these valuation factors until a deposit has been extensively drilled on closely spaced centers, which has occurred only in specific areas on the Pebble Project. Although the Company believes the expectations expressed in its forward-looking statements are based on reasonable assumptions, such statements should not be in any way construed as guarantees of the ultimate size, quality or commercial feasibility of the Pebble Project or of the Company's future performance. The likelihood of future mining at the Pebble Project is subject to a large number of risks and will require achievement of a number of technical, economic and legal objectives, including obtaining necessary mining and construction permits, completion of pre-feasibility and final feasibility studies, preparation of all necessary engineering for underground workings and processing facilities as well as receipt of significant additional financing to fund these objectives as well as funding mine construction. Such funding may not be available to the Company on acceptable terms or on any terms at all. There is no known ore at the Pebble Project and there is no assurance that the mineralization at the Pebble Project will ever be classified as ore. The need for compliance with extensive environmental and socio-economic rules and practices and the requirement for the Company to obtain government permitting can cause a delay or even abandonment of a mineral project. The Company is also subject to the specific risks inherent in the mining business as well as general economic and business conditions.
