Duluth Metals Receives NI 43-101 Report on Copper-Nickel-PGE Nokomis Deposit and Starts Scoping Study

    TORONTO, Aug. 13 /CNW/ - Duluth Metals Limited ("Duluth") (TSX: DM)
(TSX:DM.U) announces the receipt of the independent NI 43-101 compliant report
completed by 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 Roscoe Postle Associates Inc., Toronto Canada,
is the Independent Qualified Person who prepared the report which is available
on www.sedar.com or the Company website at www.duluthmetals.com.
    "This technical report summarizes the high quality polymetallic character
and consistency of the Nokomis Deposit. The deposit is primarily a
copper-nickel-PGM play but has other potential credits including gold, silver
and cobalt," stated Dr. Henry Sandri, President. "The Nokomis Deposit covers
roughly one-third of our land holdings and the company is continuing drilling
to confirm additional mineralization on the rest of our properties."
    The Technical Report details the initial resource estimate previously
announced by the Company on June 26, 2007. The resource estimate is reported
as 347 million tonnes (382 million tons) of the higher classification resource
category of Indicated Resources grading 0.62% copper, 0.20% nickel, 0.52 grams
per tonne of total precious metals (TPM = Platinum+Palladium+Gold), plus an
additional 108 million tonnes (119 million tons) of Inferred Resources grading
0.64% copper, 0.18% nickel, 0.70 grams per tonne TPM.
    "The size, extent and consistency of the mineralized resources identified
to date has prompted the Company to initiate a formal Scoping Study on the
Nokomis Deposit. At the same time we are continuing to drill step-out holes to
the East and South on the Maturi Extension Properties and to drill selective
in-fill locations. The copper and nickel variograms in the report demonstrate
the excellent consistency of copper, nickel and platinum group metal grades
and geometry in the area explored to date", said Dr. Henry Sandri, "In other
words, the Nokomis Deposit consists of big, contiguous and cohesive blocks of
copper, nickel and PGM resources."
    The Scoping Study is anticipated to be completed early in the fourth
quarter of this year. Drilling is currently underway to upgrade the Inferred
portion of the resource to Indicated. The mineralization is also open to the
east, northeast and south and the current drilling may also add substantially
to the resource in these areas. Based on the continued advancement of the
project, the Company plans to start a Pre-Feasibility Study during the fourth
quarter of 2007.
    The resource estimate, principally located in the western portion of the
property, is highlighted below and is also reported at higher cut-off grades
as follows:

    1.  CIM definitions were followed for Mineral Resource estimation and
    2.  Mineral Resources are estimated at a zone definition (wireframe) cut-
        off grade of 0.8% Cu equivalent grade (CuEq).
    3.  Mineral Resources were estimated using average long-term metal US$
        prices of $6.00/lb nickel, $2.00/lb copper, $10/lb Co,
        $950/oz platinum, $350/oz palladium and $600/oz gold.
    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%) = Cu% + 1.94 x Ni% + 1.77 x Co%
        + 0.15 x Au g/t + 0.48 x Pt g/t + 0.17 x Pd g/t
    7.  The 0.8% CuEq cut-off grade includes all material in the wireframed
    8.  TPM is Au g/t + Pt g/t + Pd g/t.
    9.  Co, Au, Pt, Pd grades, that are lacking in the few historic drill
        holes used in the estimate, have been entered in the resource
        database based on regression of assay grades from DML drill hole
    10. Resource blocks at cut-off grades up to and including 0.8% Cu form
        reasonably coherent areas that could be developed for mining.
