Duluth Metals new drill results confirm increased mineralization to Nokomis Deposit



    TORONTO, Sept. 5 /CNW/ - Duluth Metals Limited ("Duluth") (TSX: DM)
(TSX:DM.U) today announces significant assay results for 6 additional step-out
and in-fill holes drilled south of and in the central portion of the Nokomis
Deposit. Assay results from the southerly step-out drilling include MEX-49
which intersected 118.1 feet of 0.748% copper, 0.226% nickel and 1.045 grams
per tonne (g/t) of Total Precious Metals (TPM = Platinum+Palladium+Gold).
Included in that interval are 4.9 feet of 4.420% copper, 0.392% nickel and
2.989 g/t of TPM. The Nokomis Deposit is situated in the western portion of
the Maturi Extension Properties near Ely, Minnesota.
    "These new holes confirm the continuation of copper-nickel-PGE group
mineralization directly to the south on the west side of the Nokomis Resource
Block. We are extremely pleased with the infill drilling in the middle section
of the Nokomis Deposit as some of the holes have returned some of the highest
grade Total Precious Metal and silver values reported to date. Our current
drilling program is aimed at expanding our Nokomis Deposit to the south and
east in previously untested areas on our Maturi Extension Properties." stated
Dr. Henry Sandri, President and CEO. "These last 6 drill holes continue to
support our geologic models and are an indication of the potential increase in
the size and extent of our current resource block. We are encouraged by these
results as we continue to execute step-out drilling in the east and additional
in-fill drilling in the existing Nokomis Resource Block."
    Drill holes MEX-46, 48, 49, and 50 were drilled south of and within the
southern margin of the Nokomis Deposit. Currently, the farthest hole hitting
mineralization at approximately 400 metres south of the southern margin (Hole
MEX-45) of the Nokomis Resource Block is MEX 48, which returned a total
mineralized interval of 334.0 feet grading 0.463% copper and 0.133% nickel and
0.445 g/t TPM including 54.0 feet of 0.620% copper, 0.174% nickel and
0.726 g/t of TPM and 35.0 feet of 0.870% copper, 0.220% nickel and 0.826 g/t
of TPM.
    In-fill drilling in the middle section of the Nokomis Deposit returned
significant assays and demonstrate a greater thickness than is currently
estimated. Drill hole MEX-47 intersected a total mineralized interval of
285.3 feet of 0.634% copper, 0.189% nickel and 0.743 g/t of TPM including 29.5
feet of 1.022% copper, 0.354% nickel and 1.763 g/t of TPM. Drill-hole MEX-51
confirmed mineralization in the middle portion of the Nokomis Deposit
returning 73.8 feet of 0.907% copper, 0.217% nickel and 1.509 g/t of TPM.
    A 'MEX 46-51 Location Map' can be found on our Company website at
www.duluthmetals.com.
    True thickness is estimated at about 90% of core length. The following
table with (0.3% copper and 0.5% copper cut-offs) contains a more detailed

    For the 2007 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.
    A Scoping Study for the Nokomis Deposit is underway and being conducted
by Scott Wilson RPA of Toronto. The Study is anticipated to be completed in
October. The purpose of the Scoping Study is to have independent consultants
review potential mining and operational approaches and provide preliminary
project economics. The Study is based on the earlier published NI 43-101
Resource Block and metallurgical studies presently being conducted by SGS
Lakefield.

    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
Nokomis Deposit 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.
