VANCOUVER, June 4, 2013

VANCOUVER, June 4, 2013 /PRNewswire/ - Northern Dynasty Minerals Ltd.
("Northern Dynasty" or the "Company") (TSX: NDM; NYSE MKT: NAK) has filed a
205-page submission with the US Environmental Protection Agency (EPA) in
response to its call for public comments on the revised draft Bristol Bay
Watershed Assessment (BBWA), calling the draft report and process to complete
it 'biased, manipulative and contrary to EPA's own guidelines.'

Northern Dynasty President  & CEO  Ronald Thiessen  said the  2013 draft  BBWA 
released in April  suffers from the  same major shortcomings  as the  original 
report published in May 2012 - in particular, that EPA continues to assess the
environmental effects of a  hypothetical mine of its  own invention, one  that 
does not  employ modern  engineering  standards, environmental  safeguards  or 
project-specific mitigation measures and  could not be  permitted under US  or 
Alaska law.

Although EPA's 'hypothetical  mine' is sited  at the location  of the  Pebble 
deposit, BBWA  authors  continue to  refuse  to consider  the  most  extensive 
scientific data  set available  on the  region -  environmental baseline  data 
collected by  the  Pebble Limited  Partnership  (the "Pebble  Partnership"  or 
"PLP") at a cost  of some $150  million. The failure  to fully consider  PLP's 
environmental data is contrary to EPA's  own guidelines for data quality,  and 
is compounded by the fact that BBWA  study authors have never set foot on  the 
Pebble Project site.

"The Bristol Bay Watershed Assessment process has truly become the theatre  of 
the absurd," Thiessen said. "Rather than waiting for the Pebble Partnership to
submit a  proposed development  plan for  consideration by  federal and  state 
regulatory agencies  under  the  National  Environmental  Policy  Act  (NEPA), 
something that  is expected  to occur  this  year, EPA  has invented  its  own 
hypothetical  mine,  it  has  continued  to  ignore  modern  mine  engineering 
practices and  regulatory  requirements, it  has  shunned the  best  available 
scientific and environmental data at its disposal, and it has created a public
and peer review process designed to minimize scientific scrutiny of its work.

"We believe  the Bristol  Bay Watershed  Assessment process  to be  a  cynical 
effort to manipulate  public perception  about a  project before  it has  been 
proposed or undergone federal and state  permitting. And we believe the  draft 
BBWA to be a fundamentally  biased report that should  have no bearing on  the 
future of America's most important undeveloped mineral resource."

Northern Dynasty's letter to EPA Acting Administrator Bob Perciasepe states
the federal agency has further failed to provide for an open, objective and
transparent public and scientific review of the 2013 draft BBWA by
unnecessarily restricting public comment opportunities on a 1,300+ page
document and restricting public access to its Peer Review Panel, ignoring the
agency's own guidelines for scientific peer review.

"While unprecedented, Northern Dynasty said at the outset of the BBWA process
that EPA's study could have served a valuable purpose for project stakeholders
and the people of southwest Alaska if it provided an objective, science-based
assessment of the true risks and opportunities associated with modern mine
development in the region prior to the onset of project permitting," Thiessen
said. "Unfortunately in its current form, the BBWA is not an objective,
science-based assessment but a demonstrably flawed and biased document now
being used to substantial effect by the anti-development community to
manipulate public and political opinion about one of America's greatest
assets, the Pebble Project."

Other materials submitted by Northern Dynasty to EPA include:

  *a summary report with numerous examples that demonstrate how BBWA study
    authors have distorted the potential effects of a mine designed and
    operated to modern engineering standards on the natural resources of
    Bristol Bay, relating to study methodology, steady state mine operations
    and range of failure scenarios;

  *a summary of independent peer review reports on seven studies prepared by
    environmental organizations and anti-Pebble activists, all of which figure
    prominently in the 2013 draft BBWA. Although commissioned by EPA,
    assumedly to bolster the scientific credibility of the activists' studies,
    the peer reviewers instead highlight significant problems with scientific
    methodology and highly questionable or wholly inadequate conclusions;

  *a summary of EPA's failure in the 2013 BBWA reportto meaningfully address
    criticisms that the 'hypothetical mine' evaluated in the original draft
    does not employ modern engineering standards, as outlined in a report from
    Geosyntec Consultants (2012 and 2013), and directed by Dr. Michael
    Kavanaugh, a registered professional engineer and member of the National
    Academy of Engineering with 39 years of experience in water quality and
    groundwater restoration; and

  *a report on well-established and time-proven fish habitat rehabilitation,
    mitigation and enhancement practices and opportunities, which demonstrates
    the extensive opportunities to enhance fish habitat productivity in the
    Pebble Project area as part of project development. This report clearly
    contradicts the BBWA's unfounded conclusion that mitigation for potential
    fish habitat impacts associated with Pebble is not possible.

"The Pebble Project represents  far too important a  resource for the  Bristol 
Bay region, the State of Alaska and the United States to have its fate decided
by a biased and manipulative study," Thiessen said, citing the 15,000 US  jobs 
and $2.4 billion-plus annual  GDP contribution forecast  in a recent  economic 
impact         study          of         the          Pebble          Project.

"Given  the  national  significance  of   the  project  and  the   significant 
shortcomings  of  the  2013  BBWA  draft,  we  remain  confident  that  future 
development of  Pebble will  ultimately  be determined  by federal  and  state 
regulators working within the objective NEPA permitting process to enforce the
robust environmental protection standards of the United States and 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, which  will benefit not  only 
the proponent, its partners and the people and culture of the State of Alaska,
but also industries,  suppliers and consultants  locally and in  the Lower  48 
United States  of America.  The  project is  located  200 miles  southwest  of 
Anchorage on state land designated for mineral exploration and development. It
is situated  in a  region of  rolling tundra  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 ownership and direction of 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 potential mine feasibility,
economic effects, 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 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 an open pit and/or 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. The
mineralization at the Pebble Project has not yet been classified as ore and
there is no assurance that it 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 annual Form 40-F filing with the United
States Securities and Exchange Commission and its home jurisdiction filings
