TORONTO, July 21 /EMWNews/ - Duluth Metals Limited

("Duluth") (TSX: DM) (TSX:DM.U) today announces the receipt of the

independent NI 43-101 compliant report completed by Scott Wilson Roscoe

Postle Associates Inc. (Scott Wilson RPA) entitled "Technical Report on the

Resource Estimate for the Nokomis Deposit on the Maturi Extension

Properties, Minnesota, USA, prepared for Duluth Metals Limited". Richard E.

Routledge, M.Sc., P.Geo. of Scott Wilson RPA, Toronto Canada, is the

Independent Qualified Person who prepared the report which is available on

http://www.sedar.com or the Company website at http://www.duluthmetals.com.



    "This update on our Resource prepared by Scott Wilson RPA confirms good

continuity, grade and the fact that we are delineating zones of higher

grade mineralization", stated Henry J. Sandri, President and CEO. "As the

Resource is estimated on approximately 50% of our Maturi Extension

Properties, we look forward to expanding the Nokomis Deposit and seeking

out high grade exploration opportunities."



    The Updated Nokomis Resource Estimate defines 449 million tonnes

Indicated Resources grading 0.624% copper, 0.199% nickel, 0.600 grams per

tonne TPM (copper equivalent grade of 1.46%), plus an additional 284

million tonnes of Inferred Resources grading 0.627% copper, 0.194% nickel,

0.718 grams per tonne TPM (copper equivalent grade of 1.50%). (Note -

Copper Equivalent is based on US metal prices of: Copper - $1.75/lb, Nickel

- $7.00/lb, Cobalt - $10.00/lb, Gold - $600/oz, Platinum - $1,100/oz,

Palladium - $350/oz and Silver - $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.)

    1.  CIM definitions were followed for Mineral Resource estimation and

        classification.

    2.  Mineral Resources are estimated at a zone definition (wireframe) cut-

        off grade of approximately 1.0% Cu equivalent grade (CuEq).

    3.  The approximately 1.0% CuEq cut-off grade includes all material in

        the wireframed zones.

    4.  Bulk density is 3.01 t/m(3)

    5.  Resources were estimated to a maximum depth of approximately 1,350 m.

    6.  Copper equivalent (CuEq%) is based on Net Smelter Return Factors as

        determined for the Preliminary Economic Assessment by Scott Wilson

        RPA dated January 18, 2008.

    7.  Metal Prices used were $1.75/lb copper, $7.00/lb nickel, $10.00/lb

        Co, $600/oz Au, $1100/oz Pt and $350/oz Pd.

    8.  Copper equivalent (CuEq%) = Cu% + 3.03 x Ni% + 0.63 x Co%

        + 0.30 x Au g/t + 0.76 x Pt g/t + 0.24 x Pd g/t based on expected

        metal prices and process recovery and refining charges.

    9.  TPM is Au g/t + Pt g/t + Pd g/t.

    10. Co, Au, Pt, Pd grades, that are lacking in historic drill holes, have

        been entered in the resource database based on regression of assay

        grades from DML drill hole assays.

    In addition, Duluth Metals will be shortly commencing the

Pre-Feasibility Study on the Nokomis Deposit. This contract is soon to be

awarded and work should commence in August.



    The current project schedule includes ongoing infill drilling within

the Nokomis Deposit and step out drilling; ongoing studies, including

metallurgical studies for optimization; bulk sampling for large scale

metallurgical testing; environmental studies and permitting assessments;

mining engineering and planning studies, the upcoming Pre-Feasibility Study

and a Full Updated Resource Estimate in early 2009.

    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 Maturi Extension Property 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.
