VANCOUVER, March 19, 2013 /PRNewswire/ - Northern Dynasty Minerals Ltd.
("Northern Dynasty" or the "Company") (TSX: NDM; NYSE MKT: NAK) comments on
recent statements from US Senator Maria Cantwell (D-WA) regarding the
Company's comments on the US Environmental Protection Agency (EPA) draft
Bristol Bay Watershed Assessment (BBWA) report in 2012 and the Company's
disclosure of its 2011 Preliminary Economic Assessment of the Pebble
gold-copper project.

In a July 2012  news release, Northern Dynasty  stated that "the draft  (BBWA) 
assessment evaluated the potential effects  of a 'hypothetical mine  scenario' 
as determined by  the EPA, even  though this scenario  could not be  permitted 
under federal and state law." Senator  Cantwell has expressed concerns to  the 
effect that Northern  Dynasty may be  "misleading investors" because  Northern 
Dynasty is pointing out that the  Preliminary Economic Assessment was not  the 
actual basis for the EPA's hypothetical model. While the Preliminary  Economic 
Assessment presented a potential mine  development scenario at Pebble, it  was 
not intended  to  include  all  the mine  design  information  and  mitigating 
measures (as required for permitting) that  would have allowed for a  detailed 
assessment by the  EPA. According to  statements by the  EPA, the  Preliminary 
Economic Assessment formed some part of  the input into the draft Bristol  Bay 
Watershed Assessment (BBWA) report in 2012.

"Senator Cantwell's  concerns  have no  basis  in fact,"  said  Ron  Thiessen, 
President & CEO of Northern Dynasty. "While the EPA may have used some of  the 
information presented  in  our Preliminary  Economic  Assessment to  create  a 
'hypothetical mining scenario', it  is the EPA alone  that is responsible  for 
designing and then assessing the effects of the hypothetical mine in the BBWA.
To suggest that  Northern Dynasty  is responsible for  the EPA's  hypothetical 
project which was evaluated in the EPA's draft BBWA when we had no involvement
with the report is wrong."

Thiessen pointed out that:

  *Northern Dynasty's 2011 Preliminary Economic Assessment presents Northern
    Dynasty's view of a potential development plan for the Pebble Project at a
    conceptual level only for the purpose of broadly evaluating project
    economics. The 'preliminary economic evaluation' presents no detailed
    engineering, no environmental management plans, no fisheries mitigation
    considerations or other strategies for managing potential environmental
  *Many of the environmental consequences predicted in the EPA's draft
    Bristol Bay Watershed Assessment are unrelated to the project concept
    presented in Northern Dynasty's Preliminary Economic Assessment. For
    instance, the EPA's tailings embankment design and its road-building,
    culvert and pipeline design standards were derived from other sources, yet
    contribute to some of the most significant impacts predicted in the BBWA.

Northern Dynasty's Preliminary Economic Assessment and related SEC  disclosure 
filingsmeet all applicable legal standards in the United States and  Canada. 
Mr. Thiessen  also noted  that  the Pebble  Limited Partnership  (the  "Pebble 
Partnership" or "PLP") continues to  study the optimal design for  permitting, 
building and operating an environmentally sound and socially responsible  mine 
at Pebble.

"We remain  committed to  supporting PLP  as it  advances the  Pebble  Project 
through  an  unprecedented   process  of  scientific   study  and   meaningful 
stakeholder engagement," Thiessen said.  "It is unfortunate  that the SEC  has 
been wrongfully involved  in this  Alaska permitting  issue, but  it will  not 
disrupt the  commitment PLP  has made  to the  people of  Alaska to  submit  a 
sustainable mine plan  that co-exists with  healthy fisheries and  traditional 
ways of life."

About the Pebble Project

The Pebble Project is an initiative  of PLP 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 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 being 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 

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. 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
