TORONTO, February 5, 2013 /PRNewswire/ --

Duluth Metals Limited ("Duluth") (TSX: DM) (TSX:DM.U) is pleased to present
early results from the exploration program currently underway on Duluth's 100%
owned exploration properties in the Duluth Complex, northeast Minnesota. The
program has successfully identified two new mineralized areas, one consisting
of platinum group element ("PGE") mineralization on the East Shore properties
which cover the eastern margin of the South Kawishiwi Intrusion (SKI), and a
second consisting of copper-nickel-PGE mineralization within the Nickel Lake
Macrodike (NLM). The program has consisted of geologic mapping, geochemistry,
geophysics, and initial drill testing of targets on the properties which cover
8,850 acres of favorable geology adjacent to Duluth's Twin Metals Project
(Fig. 1).

"It's exciting that at the very early stages of our exploration program we
have confirmed mineralization in hotter portions of the geological system
upstream from the multi-billion ton Twin Metals Minnesota deposits," commented
Dean Peterson, Senior Vice President-Exploration of Duluth Metals.

Vern Baker, President of Duluth Metals commented, "We are pleased with the
early drill results which have confirmed sulphide mineralization in two key
areas of this massive geological system. We will be continuing with further
extensive drilling in these two areas of mineralization. One of the key focal
points of the next phase of drilling is the East Shore area where higher grade
PGM values have been returned from both surface outcrop and preliminary
drilling. In addition, the drilling in the Nickel Lake Macrodike has
identified mineralization somewhat different to the known mineralization of
the adjacent Twin Metals Project. We are currently following up with down-hole
EMP geophysical surveys and intend to continue drilling into the spring with
holes aimed at higher grade targets within deeper sections of the NLM."

Duluth is also pleased to report that Alan King, one of the world's foremost
geophysicists is being retained to consult with the Duluth Exploration team.
Mr. King's extensive worldwide expertise on nickel/copper geophysics will be a
valuable addition to Duluth's exploration efforts.

Area 1 - East Shore PGE Mineralization

The first new area of mineralization comprises PGE mineralization along the
eastern side of the SKI and within the adjacent anorthositic rocks on the East
Shore Property as shown in Figures 1 and 2. Geological mapping and geochemical
sampling of outcrops and angular boulders this summer identified
mineralization along a 2000 foot strike length zone of the eastern contact of
the SKI. Outcrop grab sampling returned TPM ^[ ^1 ^] values up to 3.5
grams/tonne (g/t) TPM, and float sampling up to 7.7 g/t TPM (Fig. 2a).
Significantly, some of the samples are characterized by high PGE to copper
sulphide ratios. The occurrence of this mineralization suggests the potential
for high-grade structure-hosted PGE mineralization, which has not been
previously recognized in the Duluth Complex.

Initial drilling in the East Shore area has confirmed anomalous TPM values in
a flat-lying zone in several holes with highlighted drill intercepts (see Fig.
2b) of PGM rich material as follows: (True thickness is estimated at about
100% of core length.)

  *12-DM-007 returned a 11.7 foot intersection of 3.28 g/t TPM including 7.3
    feet of 4.95 g/t TPM
  *12-DM-006 returned a 13.9 foot intersection of 1.63 g/t TPM including 4.8
    feet of 2.96 g/t TPM

Full assay results are shown in the following Table 1:

    Drill Hole From   To   Thickness  Cu   Ni   Pt    Pd    Au    TPM
               (ft)  (ft)    (ft)    (%)  (%)  (g/t) (g/t) (g/t) (g/t)

    including  187.9 195.2    7.3    0.02 0.02  1.03  3.83  0.09  4.95

Area 2 - Nickel Lake Macrodike Mineralization

A systematic surficial geochemical survey in the NLM has defined a series of
pronounced base-metal (Fig. 3a) and precious-metal (Fig. 3b) geochemical
anomalies. These anomalies highlight the sulfide-bearing nature of the NLM
and appear to be sourced from discrete varieties of mapped sulfide-bearing
bedrock located on the northern margin of the NLM. The significant base and
precious metal geochemical anomaly in Section 20 is currently being drill

Within the NLM, a significant thickness of disseminated Cu-Ni-PGE bearing
sulphide has been identified in the initial drilling. Notably, the mineralized
material is unlike mineralization in the nearby Spruce Road and Maturi
Deposits, having an elevated Cu:Ni ratio of 5:1. The presence of this
mineralization in the NLM confirms the existence of sulphide-bearing magmas in
the feeder conduit to the mineralized SKI. The high Cu:Ni ratio suggests
sulphide fractionation took place within the NLM, and highlights the
possibility that the system may contain zones of concentrated Ni-rich sulphide
minerals in the feeder conduit.

Significant widths of mineralization in the NLM area have been identified both
in surface outcrop and in two drill holes to date (Fig. 4). Highlights from
the drilling to date are as follows: (The mineralized body is interpreted to
dip at about 60° to the southeast. True thickness is estimated at about 95% of
core length).

  *12-DM-017 returned a 243.4 foot intersection of 0.38% copper, 0.08% nickel
    and 0.12 grams/tonne (g/t) TPM, including a 30 foot intersection of 0.50%
    copper, 0.10% nickel and 0.13 g/t TPM.
  *12-DM-018 returned a 291.0 foot intersection of 0.30% copper, 0.06% nickel
    and 0.17 g/t TPM, including a 23.7 foot intersection of 0.50% copper,
    0.09% nickel, and 0.33 ppm g/t TPM.

Full assay results are shown in the following Table 2:

               From   To   Thickness  Cu   Ni   Pt    Pd    Au    TPM
    Drill Hole (ft)  (ft)    (ft)    (%)  (%)  (g/t) (g/t) (g/t) (g/t)
    12-DM-017  91.1  334.5   243.4   0.38 0.08 0.03  0.06  0.03  0.12
    including  196.0 226.0   30.0    0.50 0.10 0.03  0.07  0.03  0.13

    12-DM-018  113.4 404.4   291.0   0.30 0.06 0.04  0.08  0.04  0.17
    including  380.7 404.4   23.7    0.50 0.09 0.10  0.15  0.08  0.33

Ongoing drilling efforts are aimed at demonstrating the continuity of this
mineralization on strike and at depth, as well as following this
mineralization to deeper sections of the NLM. Future drilling efforts within
deeper sections of the NLM will focus on looking for higher grade
mineralization analogous to that found in the Maturi Deposit and potential
concentrations of Ni-rich massive sulphide. Drilling the most prospective area
for potential concentrations of massive sulphide at the mouth of the NLM will
require summer road building, planned to commence in the spring.

Duluth is continuing with an extensive drilling program into the spring of
2013. Currently there are two drills on the NLM mineralization area and two
drills on the East Shore PGM mineralization area. Exploration drilling
discussed in this press release is shown on the maps in this Press Release

About the Sampling

Duluth Metals adheres to a rigorous QA/QC program as a part of sampling
procedures throughout the drill program. Duplicate, blank, and reference
standards are inserted into the sample stream prior to submittal the
laboratory. Half core samples are crushed and pulverized at ALS Minerals in
Thunder Bay, Ontario, and then shipped to its analytical facilities in
Vancouver, British Columbia. Samples are analyzed for Au, Pt, and Pd using a
30 gram fire assay with an ICP-AES finish, and for Cu, Ni, and other trace
elements using a four acid (near total) digestion and a combination of ICP-MS
and ICP-AES finishes. Overlimits are re-analyzed using sodium peroxide fusion,
acid dissolution, followed by an ICP-AES finish. The remaining half core
samples are stored in Minnesota.

Till samples of approximately 1 kg were collected from the B-horizon and
submitted to ALS Minerals in Thunder Bay, Ontario. Samples were dried and
sieved to -63 micron, and analyzed for Au, Pt, and Pd using a 30 gram fire
assay with an ICP-MS finish, and for Cu, Ni, and 46 other trace elements using
a four acid (near total) digestion with an ICP-MS finish. Reference standards
and field duplicates are submitted to the sample stream prior to submittal to
the laboratory, and internal laboratory standards provide a further check on
sample precision.

Standards. While such terms are recognized under Canadian securities
legislation, the United States Securities and Exchange Commission does not
recognize these terms. The term "Inferred Mineral Resource" refers to a
mineral resource for which quantity and grade or quality can be estimated on
the basis of geological evidence and limited sampling and reasonably assumed,
but not verified, geological and grade continuity. These estimates are based
on limited information and it cannot be assumed that all or any part of an
"Inferred Mineral Resource" will be upgraded to a higher classification
resource, such as "Indicated" or "Measured", as a result of continued
exploration. Accordingly, an estimate relating to an "Inferred Mineral
Resource" is insufficient to allow meaningful application of technical and
economic parameters or to enable an evaluation of economic viability. Under
Canadian securities legislation, estimates of an "Inferred Mineral Resource"
may not form the basis of feasibility or other economic studies. Investors are
cautioned not to assume that all or any part of an "Inferred Mineral Resource"
is economically or legally mineable. Investors are also cautioned not to
assume that all or any part of "Indicated" will ever be converted into
"Mineral Reserves" (being the economically mineable part of an "Indicated" or
"Measured Mineral Resource").
