Northern Dynasty Discovers New Higher-Grade Zone on East Side of Pebble Gold-Copper-Molybdenum Deposit

VANCOUVER, British Columbia--(BUSINESS WIRE)--Nov. 29, 2004--Northern Dynasty Minerals Ltd. (AMEX:NAK - News; TSX VENTURE:NDM - News)

Ronald W. Thiessen, President and CEO of Northern Dynasty Minerals Ltd. is pleased to announce that a substantial, new higher-grade gold-copper-molybdenum zone has been discovered by drilling on the east side of the Pebble deposit. This discovery, which demonstrates that there are multiple sources of mineralization, has significant implications for the deposit model and mine operations being planned. The discovery was made during the Company's comprehensive 2004 program of drilling, engineering and environmental studies designed to provide detailed data for a feasibility study and environmental impact statement for a large-scale open pit operation.

Core holes drilled on the eastern side of the Pebble deposit during the 2004 program intersected previously unrecognized, vertically and laterally extensive gold-copper-molybdenum mineralization. This mineralization, called the East Zone, is associated with an intense alteration signature, and extends east across the boundary of the Resource Lands well on to the Exploration Lands (see plan map and cross sections attached). A tabulation of assay results for East Zone discovery drill holes is attached and all results compiled to date from drilling of the Pebble deposit are posted at www.northerndynasty.com.

As presently defined, the East Zone includes holes 4136, 4137, 4149, 4155, 4181, 4188, 4210, 4250 4284, 4292, 4293, 4300, 4301, 4302 and 4303 which were drilled over an area of 2,000 feet by 2,000 feet. The East Zone is open to the north, south and east and to depth. Although there are a number of similarities with the geology and alteration in the central portion of the Pebble deposit, the favourable alteration and mineralization in the East Zone has been observed in drill holes to at least 2379 feet (725 m) in depth - much deeper than the mineralization in the Central Zone. The East Zone underlies unmineralized and unaltered Tertiary rocks that are absent at its western extent and progressively increase to a maximum thickness of 1,028 feet (310 m) in the east. Drill hole 4300 which was completed furthest to the east, intersected the strongest mineralization. Many discovery holes bottomed in mineralization with a general strengthening in molybdenum content to the east and at depth. An inferred eastern source area for the East Zone mineralization requires substantial additional drilling to establish its full potential.

The Pebble property is located in southwestern Alaska, USA. The property consists of the Resource Lands that host most of the Pebble gold-copper-molybdenum deposit, as it is currently known, and the surrounding Exploration Lands that host several porphyry gold-copper-molybdenum deposits and gold occurrences. The United States Geological Survey has listed the Pebble mineral system as the most extensive in the world (see attached Property Map).

Northern Dynasty recently exercised its option to acquire 80% of the Resource Lands from Teck Cominco American Inc. ("Teck Cominco"). In addition the Company exercised its option to acquire up to a 50% interest in the extensive surrounding Exploration Lands. Teck Cominco has a 90 day right to form a 50% joint venture on the Exploration Lands. As a consequence of exercising the Teck Cominco options, Northern Dynasty also has a 90 day period to elect whether to also acquire the 20% carried interest in the Pebble Project, held by a related party, for share consideration equal to the independently appraised value of the 20% interest. By exercising all of its options the Company can acquire up to a 100% interest in the Resource Lands (with no back-in right or royalty) and up to a 50% interest in the surrounding Exploration Lands.

Mark Rebagliati, P.Eng and Dr. Morris Beattie, P.Eng are the Qualified Persons for the Pebble Project and are 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 ALS Chemex laboratory in Fairbanks for drying, weighing and crushing. Samples are shipped by airfreight to the main ALS Chemex laboratory, North Vancouver, Canada (an ISO 9002 certified laboratory) 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.
