TORONTO, July 7, 2011 -


 

Duluth Metals Limited (”Duluth Metals”) (TSX: DM) (TSX: DM.U) is
pleased to announce assay results for 15 holes drilled on the Twin
Metals Nokomis Deposit in northeastern Minnesota, including 9 holes
containing intersections with Total Precious Metals (TPM (equal
sign) Platinum+Palladium+Gold) grades greater than 1g/t and 11
holes having intersections greater than 1.7% Copper Equivalent(x).
Three holes, Mex-211, 217 and 225, intersected significant
mineralization up to 350 metres due east of the current Nokomis
resource, thereby expanding the current mineralized area
southwards. This includes a 25 foot intersection in Mex-225,
containing 3.385 g/t TPM within a 120 foot section of 2.19g/t TPM.
Four holes, Mex-218, 220, 223 and 224 continue to confirm higher
grade assays in the Eastern Higher Grade Zone, and two holes,
Mex-212 and 219 continue to confirm higher grade assays in the B
Higher Grade Zone. The Nokomis Deposit is one of four qualified
resources within the Twin Metals Project being advanced by the
joint venture company Twin Metals Minnesota LLC.

    Highlights from expansion drilling south of
the current Nokomis Deposit include:

  • Mex-225 returned 185.0 feet of 0.710% copper, 0.184% nickel,
    3.1 g/t
    silver and 1.642 grams per tonne (g/t) Total Precious Metals
    (TPM
    (equal sign) Platinum+Palladium+Gold) (Cu Equivalent(x) of
    1.92%),
    including a 120.0 foot section of 0.835% copper, 0.230% nickel,
    3.6
    g/t silver and 2.190 g/t TPM (Cu Equivalent(x) of 2.40%), as well
    as a
    25.0 foot section of 1.100% copper, 0.325% nickel, 5.9 g/t silver
    and
    3.385 g/t TPM (Cu Equivalent(x) of 3.39%).
  • MEX-217 intersected 267.5 feet of 0.698% copper, 0.184% nickel,
    2.3 
    g/t silver and 1.139 g/t TPM (Cu Equivalent(x) of 1.72%) including
    a
    20 foot section of 0.986% copper, 0.251% nickel, 3.4 g/t silver
    and
    1.887 g/t TPM (Cu Equivalent(x) of 2.49).

    Within the Eastern Higher Grade area, drilling
highlights include:

  • Mex-224 returned 170.0 feet of 0.690% copper, 0.180% nickel,
    3.0 g/t 
    silver and 1.616 grams TPM (Cu Equivalent(x) of 1.86%), including
    a
    87.0 foot section of 0.892% copper, 0.243% nickel, 3.5 g/t silver
    and
    2.166 g/t TPM (Cu Equivalent(x) of 2.47%) as well as a 50.0
    foot
    section of 1.089% copper, 0.302% nickel, 4.2 g/t silver and 2.737
    g/t
    TPM (Cu Equivalent(x) of 3.06).
  • MEX-223 intersected 95.0 feet of 0.749% copper, 0.186% nickel,
    2.5 g/t 
    silver and 0.738 g/t TPM (Cu Equivalent(x) of 1.60%) including a
    50.0
    foot section of 1.000% copper, 0.252% nickel, 3.1 g/t silver and
    1.054
    g/t TPM (Cu Equivalent(x) of 2.17).
  • MEX-220 intersected 125.0 feet of 0.786% copper, 0.195% nickel
    4.0 g/t 
    silver and 1.566 g/t TPM (Cu Equivalent(x) of 2.00%) including a
    30.0
    foot section of 1.140% copper, 0.241% nickel, 7.1 g/t silver and
    2.125
    g/t TPM (Cu Equivalent(x) of 2.76).
  • MEX-218 intersected 80.0 feet of 0.695% copper, 0.188% nickel,
    2.9 g/t 
    silver and 0.978 g/t TPM (Cu Equivalent(x) of 1.65%) including a
    55.0
    foot section of 0.809% copper, 0.208% nickel, 3.3 g/t silver and
    1.129
    g/t TPM (Cu Equivalent(x) of 1.89).

(x) Note - Copper Equivalent is based on US metal prices of:
Copper - US$1.75/lb, Nickel - US$7.00/lb, Cobalt - US$10.00/lb,
Gold - US$600/oz, Platinum - US$1,100/oz, Palladium - US$350/oz and
Silver - US$8.50/oz, and the methodology with metallurgical
recoveries, refining costs and other charges being considered for
all metals in accordance with the Net Smelter Return Factors
contained in the January 22, 2008, NI 43-101 Scoping Study produced
by Scott Wilson RPA.

“The drilling program continues to provide results that increase
our confidence in this resource. These results also indicate that
areas of significantly higher TPMs can be identified within the
resource. Two exciting intersections with very good precious metal
results, 50 feet of 2.737g/t TPM in Mex-224 and 25 feet of 3.385
g/t TPM in Mex-225, show the potential within this resource to
define areas with higher TPM values”, stated Vern Baker, President
of Duluth Metals. “Overall, the drilling this year has been quite
encouraging. Three of the drill holes included in this release
(Mex-211, Mex-217, Mex-225) show the continuity of the resource
extending beyond the previous limits.”

A map illustrating the location of the 15 drill holes reported
in this press release, 14 of which have mineralized intercepts, can
be found on the Company website under this press release at

The Twin Metals Project now covers over 25,000 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 nickel-copper-PGM deposits within a new
emerging mining belt in Minnesota, USA.

AMEC E&C Services Inc. from Reno, Nevada has been engaged to
review and prepare a comprehensive updated NI 43-101 Resource
Report on the expanded Twin Metals Project which now includes the
Twin Metals and Franconia properties.

For the 2010-2011 Drill Program, half core samples are being
prepared at ALS Chemex Ltd. laboratories in Thunder Bay and then
shipped to its analytical facilities in Vancouver. Samples are
being analyzed for Au, Pt, and Pd using a standard fire assay with
an ICP finish and for 27 other elements using a four acid (near
total) digestion and a combination of ICPMS and ICPAES. ICP over
limits were re-analyzed using sodium peroxide fusion, acid
dissolution followed by ICPAES. The remaining half core samples are
being stored in Minnesota.

David Oliver, P. Geo. and Twin Metals Site Manager is the
Qualified Person for this press release, in accordance with NI
43-101 of the Canadian Securities Administrators, and is
responsible for the technical content and quality assurance of the
exploration data and analytical results.

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. Aside from the
joint venture, Duluth Metals retains a 100% position on
approximately 31,000 acres of mineral interests on exploration
properties adjacent to and nearby the Twin Metals Minnesota LLC
joint venture.

About Twin Metals Minnesota LLC

Twin Metals Minnesota LLC is a joint venture company, 60% owned

acquired Franconia Minerals Corporation assets from Duluth Metals
to Twin Metals, will cover more than 25,000 acres of land/mineral
interests and include four NI 43-101 compliant mineral resources:
the Nokomis Deposit, the Maturi Deposit, the Birch Lake Deposit and
the Spruce Road Deposit.(Franconia currently holds an undivided 70%
interest in the Birch, Spruce and Maturi properties and has
exercised its option to increase its interest to 82% by agreeing to
fund all of the carried interest of its joint venture partner
through to commercial production.)
