TORONTO, July 10 /CNW/ - Duluth Metals Limited ("Duluth Metals") (TSX: DM) (TSX:DM.U) today announced significant new assays for six infill and one step-out holes drilled on the Nokomis Deposit located near Ely, Minnesota. Highlights include hole MEX-109 which intersected 155.0 feet of 0.828% copper, 0.247% nickel, 1.089 grams per tonne (g/t) of Total Precious Metals (TPM (equal sign) Platinum+Palladium+Gold) and 3.2 g/t silver (Cu Equivalent(x) of 2.00%), which included 40.0 feet of 0.955% copper, 0.278% nickel, 1.527 g/t TPM and 3.9 g/t silver (Cu Equivalent(x) of 2.40%). Holes MEX-108, 109, 111, 112 and 116 all reflect significant grade increases to the head grade utilized in the 43-101 Scoping Study published on January 22, 2008. These holes continue to demonstrate that within the global resource there are significant areas of higher grade copper, nickel, TPM mineralization that will help pursue the recommendations of the Scoping Study.

In addition to MEX-109, the drilling intersected mineralized sections ranging from 30.0 to 142.7 feet as per the detailed table below and returned significant higher grade sections in a number of holes as follows:

-   MEX-108 intersected 137.7 feet of 0.899% copper, 0.249% nickel and
    0.979 g/t TPM (Cu Equivalent(x) of 2.03%), including 73.9 feet of
    1.081% copper, 0.287% nickel and 1.197 g/t TPM (Cu Equivalent(x) of
    2.40%).
-   MEX-111 intersected 142.7 feet of 0.901% copper, 0.245% nickel and
    0.957 g/t TPM (Cu Equivalent(x) of 2.02%), including 24.0 feet of
    1.094% copper, 0.289% nickel and 1.333 g/t TPM (Cu Equivalent(x) of
    2.51%).
-   MEX-112 intersected 34.5 feet of 1.175% copper, 0.270% nickel and
    1.821 g/t TPM (Cu Equivalent(x) of 2.69%), including 29.5 feet of
    1.240% copper, 0.272% nickel and 1.897 g/t TPM (Cu Equivalent(x) of
    2.79%).
-   MEX-113 intersected 30.0 feet of 0.684% copper, 0.223% nickel and
    0.989 g/t TPM (Cu Equivalent(x) of 1.74%), and in another zone,
    intersected 15.0 feet of 0.921% copper, 0.505% nickel and 0.849 g/t
    TPM (Cu Equivalent(x) of 2.78%).
-   MEX-114 intersected 44.4 feet of 0.682% copper, 0.195% nickel and
    1.686 g/t TPM (Cu Equivalent(x) of 1.91%).
-   MEX-116 intersected 44.2 feet of 0.874% copper, 0.287% nickel and
    0.920 g/t TPM (Cu Equivalent(x) of 2.12%), including 14.9 feet of
    1.214% copper, 0.378% nickel and 1.143 g/t TPM (Cu Equivalent(x) of
    2.83%), and in another zone, intersected 9.9 feet of 1.032% copper,
    0.666% nickel and 1.025 g/t TPM (Cu Equivalent(x) of 3.44%).

(x) Note to Reader: 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 - $350/0z 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 January 22, 2008, NI 43-101 Scoping Study produced by Scott
    Wilson Roscoe Postle Associates.

"Holes Mex-108 and 109 are two excellent holes which indicate the expansion of our higher grade intersections within our current Nokomis Resource Block. MEX-111, our one step-out hole to the Southwest, intersected 142.7 feet of 0.901% copper, 0.245% nickel and 0.957g/t TPM. We are especially pleased with the on-going results which demonstrate the continuity of mineralization and areas of higher grade copper, nickel and TPM intercepts within the Nokomis Deposit" stated Dr. Henry J. Sandri, President and CEO of Duluth. "We are definitely achieving one of the primary objectives of the Scoping Study in terms of delineating higher grade zones."

A more detailed summary of the assay results for holes MEX-108 to MEX-116 can be found in the table below. True width is estimated at about 90% of core length.

For the 2008 drill program, half core samples have been 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.

Currently five drills are turning on the property. Two of the rigs are continuing with large diameter PQ core drilling with the objective of providing bulk sample material for further metallurgical test work.
