Northern Dynasty Provides Update on EPA Discussions

Files Joint Motion with EPA to Extend Stay of Proceedings to May 4, 2017

VANCOUVER, March 20, 2017 /CNW/ - Northern Dynasty Minerals Ltd. (TSX: NDM; NYSE MKT: NAK) ("Northern Dynasty" or the "Company") announces that its wholly-owned subsidiary, Alaska-based Pebble Limited Partnership ("Pebble Partnership" or "PLP") and the US Environmental Protection Agency ("EPA") have filed a Joint Motion in federal court to extend a stay of proceedings in ongoing litigation under the Federal Advisory Committee Act ("FACA") to May 4, 2017 in the interest of resolving the matter.

The Company has made substantial progress in recent discussions with the EPA and intends to continue negotiating the matter directly, rather than through mediation. Government representatives are actively engaged in these discussions and, along with the Pebble Partnership, are focused on achieving a resolution that will be agreeable to both parties. In the meantime, the Court's Preliminary Injunction of November 25, 2014, will remain in effect for the duration of any stay.

"Active discussions between all parties involved have been positive and very constructive," said Tom Collier, CEO of the Pebble Partnership. "We remain confident in achieving a prompt and fair resolution that follows the rule of law, supports the interests of the parties involved and allows the Pebble Project to move into a normal course permitting process."

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, that address exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements. 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 or the outcome of litigation. Assumptions used by the Company to develop forward-looking statements include the following: the Pebble Project will obtain all required environmental and other permits and all land use and other licenses, studies and development of the Pebble Project will continue to be positive, and no geological or technical problems will occur.  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, approvals, licenses and title on a timely basis and delays due to third party opposition, changes in government policies regarding mining and natural resource exploration and exploitation, the final outcome of any litigation, completion of pre-feasibility and final feasibility studies, preparation of all necessary engineering for surface or underground mining 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. For more information on the Company, Investors should review the Company's filings with the United States Securities and Exchange Commission and its home jurisdiction filings that are available at www.sedar.com.
