Northern Dynasty reacts to negative federal Record of Decision on Alaska’s Pebble Project

November 25 , 2020 Vancouver – Northern Dynasty Minerals Ltd. (TSX: NDM; NYSE American: NAK)

("Northern Dynasty" or the "Company") announces that today, its 100%-owned, US-based subsidiary Pebble

Limited Partnership (the “Pebble Partnership”) received formal notification from the US Army Corps of

Engineers (“USACE”) that its application for permits under the Clean Water Act and other federal statutes

has been denied. The lead federal regulator found Pebble’s ‘compensatory mitigation plan’ as submitted

earlier this month to be ‘non-compliant’, and that the project is ‘not in the public interest’.

Northern Dynasty called the decision politically motivated and said it is fundamentally unsupported by the

administrative record as developed by the USACE through the Environmental Impact Statement ( “EIS”)

process for the Pebble Project. The Company intends to launch an administrative appeal of the USACE

permitting decision.

The Company notes:

“The Final EIS found Pebble to be a project of merit that would fully co -exist with clean water, healthy fish

and wildlife populations, and the important fisheries resources of southwest Alaska. The Final EIS also found

that Pebble would make an important , positive socioeconomic contribution to the people and villages of

Bristol Bay, Alaska – where full-time jobs are scarce and people face one of the highest costs of living in the

country – as well as to the State of Alaska and the United States.

“Based on the positive findings of the Final EIS, conclusions by the USACE that development of the Pebble

Project is ‘not in the public interest’ are wholly unsupported.

“At a time when the United States h as declared a ‘national emergency’ due to its over -reliance on foreign

producers for critical minerals required to ensure the country’s future economic and military security, it is

unconscionable to determine that permitting and development of one of the g reatest accumulations of

strategic and critical minerals ever discovered on American soil is ‘not in the public interest’.

“President-elect Biden’s campaign recently said his administration would support boosting domestic

production of copper and other met als necessary for the production of clean and renewable energy

technologies, and a transition to a lower carbon future.”

Northern Dynasty confirmed that the Pebble Partnership will appeal the USACE permitting decision within

the 60-day window provided for it to do so.

“For the United States to turn its back on an opportunity to develop these minerals here at home in a manner

that US regulators have agreed is environmentally safe and responsible, and to do so for purely political

reasons, is not just short -sighted,” said Northern Dynasty President & CEO Ron Thiessen. “It’s self -

destructive.”
