Northern Dynasty Minerals Ltd. - Pebble Deposit Drilling Results Update

VANCOUVER, Nov. 20 /CNW/ - Northern Dynasty Minerals Ltd. ("Northern
Dynasty" or the "Company") (TSX: NDM; AMEX: NAK) reports that core drilling
activities at the Pebble Limited Partnership's ("PLP", "Pebble Partnership" or
the "Partnership") project site in southwest Alaska continue to intersect long
intervals of higher grade mineralization, and demonstrate a very high level of
continuity within the Pebble deposit.
The focus of the Partnership's 2008 drill program is to upgrade the
classification for a large portion of the mineral resource in the Pebble East
area and to delineate the deposit's extent and overall geometry in order to
facilitate comprehensive mine planning. To early November 2008, PLP crews had
completed 123,000 feet of drilling in 27 infill and step-out holes. Results
have been received for 18 holes (numbered 8401 through 8416, 8419 and 8421),
and assays are pending for seven other holes. Drilling is ongoing with six
rigs working on new holes.
"The primary goal of the 2008 drill program is to allow the Partnership
to finalize a Prefeasibility Study next year," said Northern Dynasty President
& CEO Ron Thiessen. "The results we are releasing today are fully consistent
with that goal. Not only do they confirm the consistency and tenor of the
Pebble deposit, but also the potential to expand the mineral resource in
future."
Thiessen said a revised mineral resource estimate for the Pebble deposit
will be complete before year end, and is expected to move a significant
proportion of the mineralization in the Pebble East area from an inferred to
an indicated category. He added that Northern Dynasty plans to cease reporting
on the Pebble West and Pebble East zones separately, and publish a single
mineral resource estimate for the overall Pebble Deposit.
A Table of 2008 Pebble Deposit Assay Results is included with this news
release and a Drill Hole Location Plan Map is posted on Northern Dynasty's
website www.northerndynastyminerals.com/ndm/NewsReleases.asp.

Highlights include:

- Hole 8405 intersected 2,460 feet grading 1.20% copper equivalent
(CuEQ(1)) (0.78% Cu, 0.25 g/t Au, 0.046% Mo). Included in this
intersection is a 386 foot interval grading 1.87% CuEQ (1.40% Cu,
0.16 g/t Au, 0.066% Mo).
- Hole 8410 intersected 1,525 feet grading 1.21% CuEQ (0.80% Cu, 0.44
g/t Au, and 0.023% Mo). Included in this intersection is a 730 foot
interval grading 1.44% CuEQ (0.92% Cu, 0.57 g/t Au, 0.027% Mo).
- Hole 8412 intersected 1,301 feet grading 1.76% CuEQ (1.11% Cu, 0.69
g/t Au, and 0.038% Mo). Included in this intersection is a 649 foot
interval grading 1.96% CuEQ (1.34% Cu, 0.65 g/t Au, 0.036% Mo).
- Hole 8413 intersected 2,469 feet grading 1.15% CuEQ (0.80% Cu, 0.20
g/t Au, and 0.040% Mo). Included in this intersection is a 1789 foot
interval grading 1.32% CuEQ (0.96% Cu, 0.23 g/t Au, 0.036% Mo).
- Hole 8414 intersected 1,224 feet grading 1.27% CuEQ (0.60% Cu, 0.80
g/t Au, and 0.027% Mo). Included in this intersection is a 796 foot
interval grading 1.42% CuEQ (0.59% Cu, 1.06 g/t Au, 0.024% Mo).
- Hole 8515 intersected 2009 feet grading 1.15% CuEQ (0.64% Cu, 0.54
g/t Au and 0.029% Mo). Included in this intersection is a 1060 feet
interval grading 1.52% CuEQ (0.81% Cu, 0.84 g/t Au and 0.028% Mo).

Of particular note, hole 8413 (2,469 feet grading 1.15% CuEQ)
demonstrates the strength of the mineralizing system in the central part of
Pebble East. Holes 8410, 8412, 8414 and 8415 drilled in the southeast, holes
8408, 8411 and 8419 drilled in the northwest, and hole 8404 drilled in the
south, tested for the extent of the deposit. The positive results from these
holes confirm the open-ended potential in these areas.
The 2008 drilling program has also contributed significantly to the
geological and structural understanding of the Pebble deposit which will
assist with the Prefeasibility Study work.
"Pebble continues to distinguish itself as one of the world's great
mineral deposits, with the potential to support a modern, long-life mine that
delivers substantial benefits to shareholders, local communities and the State
of Alaska," Thiessen said. "Based on the positive drill results released
today, and ongoing progress made by the project's engineering, environmental
and stakeholder relations teams, the Pebble Partnership remains on track to
finalize a Prefeasibility Study in the latter half of 2009 and commence
project permitting in early 2010."

Comments on Forward Looking Information, Estimates 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.
Subsequent results and developments may differ materially from those
postulated in the estimates and forward-looking statements. Other factors that
could cause the Company's actual results and performance to differ materially
from those in forward-looking statements include adverse market prices for
metals, the conclusions of detailed feasibility and technical analyses, lower
than expected grades and quantities of resources, mining rates and metal
recovery rates and the fact that necessary capital may not be available to the
Company on terms acceptable to it or at all. 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 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 20-F filing with the United States Securities
and Exchange Commission and its home jurisdiction filings that are available

<<
Information about CuEQ
>>

Copper equivalency or "CuEQ" is a manner of expressing poly-metallic
deposits as a grade of the principal mineralization (by value). As used
herein, gold and molybdenum values have been expressed as part of the copper
grade. CuEQ as calculated herein is based on assumed metal prices of
US$1.80/lb for copper, US$800/oz for gold, and US$10.00/lb for molybdenum.
Copper equivalent has not been adjusted for metallurgical recoveries.
Adjustment factors to account for differences in relative metallurgical
recoveries for gold, copper and molybdenum depend upon the completion of
definitive metallurgical testing. Significant shifts in the relative values of
these metals can significantly change the CuEQ. CuEQ is provided for
illustrative purposes only.

<<
Information Concerning Estimates of Measured, Indicated
and Inferred Resources
>>

This news release uses the terms "measured resources", "indicated
resources" and "inferred resources". Northern Dynasty Minerals Ltd. advises
investors that although these terms are recognized and required by Canadian
regulations (under National Instrument 43-101 Standards of Disclosure for
Mineral Projects), the U.S. Securities and Exchange Commission does not
recognize them. Investors are cautioned not to assume that any part or all of
the mineral deposits in these categories will ever be converted into reserves.
In addition, "inferred resources" have a great amount of uncertainty as to
their existence, and economic and legal feasibility. It cannot be assumed that
all or any part of an Inferred Mineral Resource will ever be upgraded to a
higher category. Under Canadian rules, estimates of Inferred Mineral Resources
may not form the basis of feasibility or pre-feasibility studies, or economic
studies except for Preliminary Assessment as defined under 43-101. Investors
are cautioned not to assume that part or all of an inferred resource exists,
or is economically or legally mineable.
