TORONTO, November 15, 2012 /PRNewswire/ --

  *Drill results of the remaining 23 holes (MEX-409 to MEX 436) in the Maturi
    Deposit to be used in the final pre-feasibility AMEC resource report
  *Approximately 159 additional drill holes and 70 wedge offsets for the
    Maturi Deposit, including these 23 holes featured in this press release,
    will be factored into the final pre-feasibility AMEC resource numbers due
    later this month (November 2012)
  *The final pre-feasibility AMEC resource estimate report will confirm the
    extent and distribution of the higher grade portions of the deposit the
    presence of which is indicated by the current drill results

Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX: DM.U) is pleased to
announce assay results for 23 additional holes, MEX-409 to 436, on the Maturi
Deposit within the Twin Metals Minnesota Project in northeastern Minnesota.
Assay results highlight Area 1 (shallow west Maturi) , where 16 of the 17
drill holes have significant length intercepts with average grades over 0.7%
copper that meet a 0.5% Cu cut-off criteria. These holes, distributed across
the Maturi Resource, continue to indicate the ability to define a higher grade
sub-set of the resource for initial mine planning. These additional holes will
be incorporated into the final resource estimate to be issued by AMEC later
this month (November 2012).

"These holes continue to show the continuity, thickness, and grade that will
provide us a strong resource estimate on which we can base the pre-feasibility
mine planning." stated Vern Baker, President of Duluth Metals. "The additional
holes being added to the resource estimate have been very encouraging and will
provide for a very robust estimate. The pre-feasibility study is also focusing
on evaluating the optimum scale, location, mining method, and metallurgical
process for the Twin Metals Minnesota Project."

Drilling highlights in the western section of the Maturi Deposit include:

In Area 1 (shallow west Maturi):

  *Mex-422M returned a 155 foot intersection of 0.917% copper, 0.279% nickel,
    4.1 g/t silver and 0.639 grams TPM (TPM = Platinum+Palladium+Gold) at a
    0.5% Cu cut-off.
  *Mex-430M returned a 180 foot intersection of 0.896% copper, 0.256% nickel,
    3.3 g/t silver and 0.689 grams TPM at a 0.5% Cu cut-off.
  *Mex-412 returned a 152 foot intersection of 0.896% copper, 0.262% nickel,
    3.1 g/t silver and 0.692 grams TPM at a 0.5% Cu cut-off.
  *Mex-421M returned a 121.25 foot intersection of 0.889% copper, 0.250%
    nickel, 3.4 g/t silver and 0.617 grams TPM at a 0.5% Cu cut-off.

In Area 2 (deeper west Maturi):

  *Mex-409 returned a 137 foot intersection of 0.833% copper, 0.279% nickel,
    2.7 g/t silver and 0.817 grams TPM at a 0.5% Cu cut-off.
  *Mex-436M returned a 168 foot intersection of 0.746% copper, 0.264% nickel,
    2.4 g/t silver and 0.544 grams TPM at a 0.5% Cu cut-off.

The Twin Metals Minnesota Project covers over 32,000 acres of land/mineral
interests and consolidates the largest base and precious metal land position
in Minnesota. This extensive land position provides Twin Metals with the
platform to plan and develop one the world's largest copper-nickel-PGM
deposits within a new emerging mining belt in Minnesota, USA.

For the 2011-2012 Drill Program, half core samples are being prepared at ALS
Minerals laboratories in Thunder Bay and then shipped to its analytical
facilities in Vancouver. Samples are being analyzed for Au, Pt, and Pd using a
30g standard fire assay with an ICP-AES finish and for 33 other elements using
a four acid (near total) digestion and a combination of ICP-MS and ICP-AES.
ICP over-limits for copper and nickel are re-analyzed using dissolution four
acid (near total) digestion followed by ICP-AES or AAS. The remaining half
core samples are being stored in Minnesota.

Phillip Larson, P. Geo. is the Qualified Person for Duluth Metals and Senior
Geologist for Duluth Metals, in accordance with NI 43-101 of the Canadian
Securities Administrators, and is responsible for Duluth Metals technical
content of this press release and quality assurance of the exploration data
and analytical results.

About Duluth Metals Limited

This press release contains forward-looking statements (including
"forward-looking information" within the meaning of applicable Canadian
securities legislation and "forward-looking statements" within the meaning of
the US Private Securities Litigation Reform Act of 1995) relating to, among
other things, the results of drilling operations of Duluth Metals and
exploration and mine development.  Generally, forward-looking statements can
be identified by the use of words such as "plans", "expects" or "does not
expect", "is expected", "budget", "scheduled", "estimates", "forecasts",
"intends", "anticipates" or "does not anticipate", or "believes", or
variations of such words and phrases or statements that certain actions,
events or results "may", "could", "would", "might" or "will be taken", "occur"
or "be achieved".  Duluth Metals has relied on a number of assumptions and
estimates in making such forward-looking statements, including, without
limitation, the prices of copper, nickel and platinum group metals (PGMs) and
the costs associated with continuing exploration and mining development. 
Such assumptions and estimates are made in light of the trends and conditions
that are considered to be relevant and reasonable based on information
available and the circumstances existing at this time. A number of risk
factors may cause actual results, level of activity, performance or outcomes
of such exploration and/or mine development to be materially different from
those expressed or implied by such forward-looking statements including,
without limitation, whether such discoveries will result in commercially
viable quantities of such mineralized materials, the possibility of changes to
project parameters as plans continue to be refined, the ability to execute
planned exploration and future drilling programs, possible variations of
copper, nickel and PGM grade or recovery rates, the need for additional
funding to continue exploration efforts, changes in general economic, market
and business conditions, and those other risks set forth in Duluth Metals'
most recent annual information form under the heading "Risk Factors" and in
its other public filings.  Statements related to "reserves" and "resources"
are deemed forward-looking statements as they involve the implied assessment,
based on realistically assumed and justifiable technical and economic
conditions, that an inventory of mineralization will become economically
extractable.  Forward-looking statements are not guarantees of future
performance and such information is inherently subject to known and unknown
risks, uncertainties and other factors that are difficult to predict and may
be beyond the control of Duluth Metals.  Although Duluth Metals has attempted
to identify important risks and factors that could cause actual actions,
events or results to differ materially from those described in forward-looking
statements, there may be other factors and risks that cause actions, events or
results not to be as anticipated, estimated or intended.  Consequently, undue
reliance should not be placed on such forward-looking statements. In addition,
all forward-looking statements in this press release are given as of the date
hereof.  Duluth Metals disclaims any intention or obligation to update or
revise any forward-looking statements, whether as a result of new information,
future events or otherwise, save and except as may be required by applicable
securities laws.  The forward-looking statements contained herein are
expressly qualified by this disclaimer.
