Duluth Metals Geologic Model Targets Higher Grade Base & Precious Metal Zones in Nokomis Deposit

TORONTO, Canada - Duluth Metals Limited (”Duluth Metals”) (TSX: DM) (TSX:DM.U) today
announced that the results of advanced geological modelling and analysis of
the Nokomis base and precious metal deposit, are beginning to identify and
characterize higher grade copper, nickel, platinum, palladium and gold zones
within the deposit, and potentially define contiguous, large tonnage - higher
grade zones that will be important in the evaluation of future mining
scenarios. This geological analysis forms part of the Company’s current work
program on the combined base and precious metal Nokomis Deposit, which also
includes mine planning, metallurgical studies, infrastructure analysis,
project optimization, and environmental baseline studies required for future
permitting.

The modeling currently led by Dean Peterson, Duluth Metals Senior VP
Exploration and Duluth Metals staff is providing a new understanding of the
origin of and the controls on grade distribution within the Nokomis Deposit.
The geologic models provide confidence in the search parameters and
variography of the block models and subsequent grade - tonnage estimates.
Duluth Metals is commissioning a new 43-101 resource estimate which will
include 155 drill holes and 63 wedges as part of its higher grade zone
targeting effort.

“This work has gone a long way to explaining why we have much higher than
typical Duluth Complex grades in many areas within our very large deposit,”
stated Duluth Metals’ President and CEO, Dr. Henry J. Sandri. “This kind of
understanding of the origin of, and the spatial distribution of our higher
grade material will be key not only in defining new high grade areas, but
will also be instrumental in assisting us to optimize the economics of our
current resource.”

The modeling has identified and provided an understanding of the origin
of and controls on the distribution of four distinct types of higher-grade
Copper-Nickel-Platinum-Palladium-Gold mineralization within the Nokomis
Deposit mineralized system.

<<
- Platinum Group Element- rich disseminated mineralization within the
SKI on the Eastern side of the Nokomis Property. This area is known
as the Eastern High Grade Corridor (21 drill holes as press released
October 27, 2008). This large coherent zone of significantly higher
grade PGE mineralization is the result of the initial constriction of
the magma channel beneath a large block of older rocks within the
Nokomis Deposit. Such a blockage impedes the flow of crystals and
sulfide droplets. However, the liquid portion of the magma continues
to flow along with its dissolved Platinum Group Elements ("PGE").
Once these dissolved and flowing PGE's come in contact with a stuck
sulfide droplet, they instantly dissolve into the sulfide and
increase the PGE grade of the sulfide.

- Nickel-Cobalt enriched semi-massive sulfide mineralization at the
base of the SKI (or immediately below) the main magma channelway
through the Nokomis Deposit. This mineralization is believed to have
formed by continuous flushing of hot magma through the channelway
which melted footwall granitic rocks. These granitic melts were
incorporated into the magma and induced the formation of new sulfide
minerals beneath a crystal slurry. These new sulfides scrubbed the
melt of nickel and cobalt and settled to the bottom of the system.

- Copper-PGE enriched disseminated mineralization deep in the footwall
below the magma channel. The ever-deepening (into the melting
footwall) magma channel induced and pinned hydrothermal convection
cells in the footwall beneath the magma channel. The water in the
system was released from the footwall granitoids by thermal
metamorphism and circulated Cu-PGE downwards beneath the channel way.

- Top-Loaded Cu-PGE enriched disseminated mineralization in the SKI. To
the sides of the magma channel way, the sulfide-bearing crystal-
liquid slurry was intruded as batches of magma out and to the sides
of the channel. Since these highly crystalline magmas are distal to
the very hot main magma channel, they solidified quickly into
sulfide-bearing troctolite. Once the silicates (olivine+plagioclase)
are solid, buoyant fractionated sulfide (Cu-PGE) liquid and magmatic
waters moved upwards through the solidifying crystal pile and
precipitated Cu-PGE sulfide and hydrous silicate minerals beneath the
overlying crystal-poor, liquid silicate magma.

About Duluth Metals

Duluth is committed to acquiring, exploring and developing copper, nickel
and platinum group metal (PGM) deposits. Duluth’s principal property is the
Nokomis Deposit located within the rapidly emerging Duluth Complex mining
camp in northeastern Minnesota. The Duluth Complex hosts one of the world’s
largest undeveloped repositories of copper, nickel and PGMs, including the
world’s third largest accumulation of nickel sulphides, and one of the
world’s largest accumulations of polymetallic copper and platinum group
metals.
