SUCCESSFUL DRILLING CONTINUES AT PEBBLE
NORTHERN DYNASTY COMMENCES STUDIES TO DEVELOP WORLD CLASS GOLD-COPPER MINE
November
4, 2003, Vancouver, BC - Ronald Thiessen, President and CEO of Northern
Dynasty Minerals Ltd. (TSX Venture: NDM; OTCBB: NDMLF) is pleased to announce
further assay results from the core drilling program being completed within
the giant Pebble gold-copper-molybdenum deposit located in southwestern Alaska.
With the outstanding results received from this drill program, Northern Dynasty
will now rapidly advance the Pebble project towards completion of a final
feasibility study for a large-scale, open pit, gold-copper-molybdenum mine.
The project is expected to compare favourably with the world's important
gold-copper mines. A strengthening gold price and the recent substantial increase
in the copper price provide a very favourable platform to advance the Pebble
project.
Northern Dynasty will finish the current 65,000 feet (20,000 metres) of drilling
in November at hole 3135. It is expected that this drilling program is confirming
significant additional resources and a new resource estimate for the Pebble
deposit will be completed in December. This work will be followed by a preliminary
economic assessment of the project by an internationally recognized third
party engineering group. In early spring a major, in-fill, grid drilling program
is scheduled to allow detailed production planning of in-pit resources. Further
details of Northern Dynasty's plans to rapidly move the Pebble Project
to final feasibility status will be announced in the next few months.
Results from newly completed drill holes are reported below and a drill hole
location map is attached to this news release and posted at www.northerndynasty.com.
One of the highlights is step-out drill hole 3114, located 220 metres outside
the southeastern boundary of the Pebble deposit. Hole 3114 intersected 380
feet (115.8 metres) grading 0.98% copper equivalent1 and opens
up the southeastern side of the Pebble deposit to dramatic expansion of the
higher-grade mineralization. Another new highlight is the successful extension
to depth of holes 3082, 3085 and 3086. As these previously drilled holes had
bottomed in gold-copper mineralization they were re-entered and drilled deeper.
Results from these holes clearly show that the Pebble deposit's resources
extend to greater depth.

Note 1
Copper equivalent calculations use metal prices of US$0.80/lb for copper,
US$350/oz for gold, and US$4.50/lb for molybdenum. Copper equivalent estimates
have not been adjusted for metallurgical recoveries of gold and copper. Molybdenum
recovery is assumed to be 60%. Adjustment factors to account for differences
in relative metallurgical recoveries for gold, copper, and molybdenum will
depend upon the completion of definitive metallurgical testing.
CuEQ = Cu(%) + (Au (g/t) x 11.25/17.64) + (Mo(%) x 59.52/17.64)
The Pebble deposit
is one of the world's largest undeveloped gold and copper resources. Prior
to Northern Dynasty's extensive drill program this year, Snowden Mining
Industry Consultants Inc. estimated an inferred mineral resource for the deposit
of 1.0 billion tonnes grading 0.61% copper-equivalent1 (0.40 g/t
Au, 0.30% Cu, and 0.015% Mo above a cut-off grade of 0.30% copper equivalent).
This resource estimate contains 13.1 million ounces of gold and 6.8 billion
pounds of copper. It is based on 80 holes drilled by Teck Cominco American
Incorporated over the period 1988 to 1997; these holes were widely spaced
from 100 to 250 metres apart throughout much of the deposit and up to 300
metres apart near the margins. Perhaps more importantly, Snowden also established
for the first time that the deposit contains significant amounts of higher-grade
resources: 271 million tonnes of 0.86% copper-equivalent (0.59 g/t Au, 0.43%
Cu and 0.018% Mo above a cut-off grade of 0.70% copper-equivalent). The copper
equivalent values for the mineral resource and recently released drill hole
information were determined using a copper price of US$0.80/lb. As Pebble
has a huge copper and gold resource, rising commodity prices, like the recent
increase in copper to over $0.90/lb, would have a significant impact on future
revenues.
Pebble deposit mineralization is very continuous with almost no internal waste
and is persistent over a broad area measuring at least 1.7 kilometres E-W
by 1.7 kilometres N-S. Mineralization begins right at the bedrock surface,
which is covered only by a thin veneer of gravels ranging from 5 to 25 metres
thick, indicating the deposit will have an unusually low stripping ratio.
The deposit remains unconstrained, allowing for expansion in most directions
and to the east under Tertiary cover. Its total depth extent is unknown. Many
of Teck Cominco's widely spaced holes, which averaged 163 metres deep,
bottomed in mineralization (50% bottomed in 0.60% copper equivalent or better).
The size of the Pebble deposit is expected to increase with delineation drilling
to depth and outside the Snowden resource estimate boundary.
The Pebble deposit comprises only 5% of a giant, 89 square-kilometre sulphide
system that is covered by the property. Recently, the United States Geological
Survey listed the Pebble mineralized system as the most extensive in the world.
Large-scale porphyry systems such as these commonly host multiple deposits.
Since commencing exploration work last year at Pebble, Northern Dynasty has
made several new deposit discoveries and established many other targets for
developing substantial gold, copper and molybdenum resources within this giant
mineralized system. In addition to the twelve new holes (announced above)
that were drilled in the Pebble deposit area, Northern Dynasty also completed
two new exploration holes, numbered 3107 and 3109, located 2,000 metres and
2,500 metres north of the Pebble deposit. These holes intersected low-grade
stockwork gold mineralization over considerable lengths (130 metres grading
0.37 g/t Au and 52 metres grading 0.33 g/t Au).
Northern Dynasty is focused on developing an entire mineral district at its
Pebble gold-copper-molybdenum project. Both access and infrastructure are
favourable for development. Located in southwestern Alaska in a region of
low rolling hills with an average elevation of only 300 metres above sea level,
the district also enjoys a more favourable winter climate than much of the
north-central United States. The project is situated only 132 kilometres from
tidewater along a proposed road route to a year round deep-sea port on Cook
Inlet. The town of Iliamna, 25 kilometres from the project, has an airport
with two 1500-metre paved runways that serve 3 daily scheduled flights from
Anchorage.
Northern Dynasty is a Hunter Dickinson Inc. managed company with 30.1 million
shares outstanding. Hunter Dickinson Inc. companies have a strong record of
success in exploring and developing large gold-copper porphyry projects, several
of which have yielded exceptional returns for their shareholders.
Mark Rebagliati, P.Eng, is the Qualified Person for the Pebble Project and
is supervising the quality control and quality assurance program. Logging
and sampling is completed in Northern Dynasty's secure facility at Iliamna,
Alaska. The NQ-size core is mechanically split and samples are transported
to the SGS Mineral Services laboratory in Fairbanks for sample preparation.
Sample pulps are shipped by airfreight to SGS Canada Inc., Toronto, Canada
(an ISO 9002 certified laboratory) for analyses. Gold is determined by Fire
Assay (FA) fusion with an Atomic Absorption Spectroscopy (AAS) finish. For
results greater than 2,000 ppb gold, samples are re-analyzed by one-assay-ton
FA fusion with a gravimetric finish. Copper assays are conducted with sodium
peroxide fusion and Inductively Coupled Plasma-Emission Spectroscopy (ICP-ES)
finish. All samples are analyzed for Cu and Mo, and 31 additional elements
by aqua regia digestion ICP-ES. Northern Dynasty includes standards and duplicates
in addition to the laboratory's internal quality control work.
