TORONTO, Feb. 5, 2013

TORONTO, Feb. 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)
12-DM-006  187.9 201.8   13.9    0.24 0.08  0.41  1.05  0.18  1.63
including  192.2 197.0    4.8    0.50 0.16  0.75  1.81  0.41  2.96
12-DM-007  187.9 199.6   11.7    0.04 0.02  0.69  2.48  0.10  3.28
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:

Drill Hole From   To   Thickness  Cu   Ni   Pt    Pd    Au    TPM
           (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 
(Figures  1-4),  which  can   also  be  found  on   the  Company  website   at

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.

Cautionary Note to United States  Investors Concerning Estimates of  Indicated 
and Inferred Mineral Resources
This press release uses the terms "Indicated Mineral Resources" and  "Inferred 
Mineral Resources"  in  accordance  with the  Canadian  Institute  of  Mining, 
Metallurgy and  Petroleum (CIM)  Definition 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").
