NEW RESOURCE ESTIMATE CONFIRMS PEBBLE EAST AS ONE OF THE WORLD'SMOST
IMPORTANT COPPER-GOLD-MOLYBDENUM DEPOSITS
- 3.4 billion tonnes grading 1.00% copper equivalent, containing 42.6 billion pounds of copper, 39.6 million ounces of gold, and 2.7 billion pounds of molybdenum.
At a 1.00% copper equivalent cut-off, the estimated inferred mineral resources are:
- 1.4 billion tonnes grading 1.29% copper equivalent, containing 24.6 billion pounds of copper, 20.9 million ounces of gold, and 1.2 billion pounds of molybdenum.
A summary of mineral resources for the Pebble East deposit at various cut-off grades is tabulated below (see also Pebble Project Deposit Plan and Section posted on Northern Dynasty's website at www.northerndynasty.com):

Note
1 By prescribed definition, "Mineral Resources" do not have demonstrated
economic viability. An Inferred Mineral Resource is that part of a mineral
resource for which quantity and grade can be estimated on the basis of geological
evidence and limited sampling and reasonably assumed, but not verified, geological
and grade continuity.
Note 2 Copper equivalent calculations use metal prices of US$1.00/lb for copper,
US$400/oz for gold, and US$6.00/lb for molybdenum. Copper equivalent has not
been adjusted for metallurgical recoveries. Adjustment factors to account
for differences in relative metallurgical recoveries for copper, gold and
molybdenum will depend upon the completion of definitive metallurgical testing.
CuEQ = Cu % + (Au g/t x 12.86/22.05) + (Mo% x 132.28/22.05).
Note 3 A 0.30% CuEQ cut-off is considered to be comparable to that used for
porphyry deposit open pit mining operations in the Americas. For bulk underground
mining higher cut-offs, such as 0.60% CuEQ, are typically used. All cut-offs
are subject to a feasibility study.
Note 4 The resources estimate for Pebble East was prepared by the technical
staff of Northern Dynasty and audited by independent consultants, Scott Wilson
Roscoe Postle Associates.
The new Pebble East resource
estimate is based upon assay results from 132 core holes drilled in the Pebble
East area. The estimate was prepared by the technical staff of Northern Dynasty
and audited by industry leading geological and mining consultants at Scott
Wilson Roscoe Postle Associates Inc., under the direction of David W. Rennie,
P. Eng., an independent Qualified Person as defined by National Instrument
43-101. A technical report detailing the resource estimate will be filed on
www.sedar.com within 45 days.
The 2006 drilling program at Pebble East expanded the north-south length of
the deposit to over 7000 feet, with grades over this extent consistently exceeding
1% copper equivalent. The deposit remains open for expansion to the north
and to the south across a width exceeding 4000 feet. Importantly, significant
amounts of high-grade copper minerals (predominantly bornite) were intersected
during 2006 in the northern most holes drilled and also in holes near the
southern most area drilled. The presence of significant bornite mineralization
in these holes indicates their proximity to mineralizing centers which are
open to extension and appear to be strengthening to the north and to the south.
Northern Dynasty met its target of early February to re-commence drilling
at the Pebble Project site. Four rigs are now active, with plans to ramp up
to 8 rigs by April.
The 2007 program will focus on Pebble East and consist of two components:
delineation drilling and infill drilling. Delineation drilling will contribute
to further expansion of resources and the infill drilling will upgrade the
classification of known mineralization. Delineation drilling in the order
of 100,000 feet will focus on extending the Pebble East deposit to the north
and south and also define its eastern and western limits. Infill drilling,
comprising approximately 150,000 feet, is also planned with the focus on upgrading
the resource classification of the highest grade 1 billion tonnes of the deposit.
The Pebble East discovery
is a substantial addition to the Pebble Project. The mineral resources and
the metals contained in the near surface Pebble West deposit, as announced
in March 2005 are listed for comparison in Tables 2 and 3 below.

Mark Rebagliati, P.Eng., is the Qualified Person supervising the quality control and assurance program for the Pebble Project. Logging and sampling is completed in Northern Dynasty's secure facility at Iliamna, Alaska. The NQ-size core is split and samples are transported to the ALS Chemex laboratory in Fairbanks for drying, weighing and crushing. Samples are shipped by airfreight to ALS Chemex laboratories in, North Vancouver, Canada (ISO 17025 accredited) and Sparks, Nevada (ISO 9001:2000 certified) for final preparation and analysis. Gold is determined by 30 g Fire Assay (FA) fusion with an Atomic Absorption Spectroscopy (AAS) finish. Copper and molybdenum assays are by four acid digestion with an Inductively Coupled Plasma-Emission Spectroscopy (ICP-ES) finish. All samples are also analyzed for 23 additional elements by four acid digestion ICP-ES. Northern Dynasty includes standards, duplicates and blanks in addition to the laboratory's internal quality control work. Duplicate samples are analyzed by Acme Analytical Laboratories of Vancouver, Canada. |
