Duluth Metals hits higher grade mineralization in Eastern Area



    TORONTO, March 4 /CNW/ - Duluth Metals Limited ("Duluth Metals")
(TSX: DM) (TSX:DM.U) today announced it had intersected higher grade
mineralization in four holes in the Eastern Area of the Maturi Extension
Properties in Minnesota. Holes MEX-77, 78, 80 and 82 confirm the presence of
higher grade mineralization in parts of the Eastern Area, relative to that in
the initial NI 43-101 qualified Nokomis Resource. (See press release dated
June 26, 2007.) In comparing only these four holes, MEX-77, 78, 80 and 82 in
our Eastern Area (using a 0.5% copper cut-off) returned an average 40%
increase in the copper grade, a 26% increase in the nickel grade, a 154%
increase in the gold grade, a 222% increase in the platinum grade, a 220%
increase in the palladium grade and a 211% increase in the TPM grades relative
to the average grade of the Indicated Resource portion of the overall Nokomis
Resource.
    Of particular note is Hole MEX-78 which returned 123.1 feet of 0.905%
copper and 0.264% nickel with 1.426 grams per tonne (g/t) of Total Precious
Metals (TPM = Platinum+Palladium+Gold) and 3.7 g/t silver, including 113.3
feet of 0.941% copper, 0.274% nickel, 1.513 g/t TPM and 3.8 g/t silver, with a
49.2 foot section of 1.167% copper, 0.351 % nickel, 1.781 g/t TPM and 4.2 g/t
silver. Hole MEX-80 intersected 88.6 feet of 0.689% copper, 0.209% nickel,
1.882 g/t TPM and 3.5 g/t silver including 49.2 feet of 0.916% copper, 0.258 %
nickel, 2.361 g/t TPM and 4.8 g/t silver with a 14.9 foot section of 1.262%
copper, 0.380 % nickel, 3.795 g/t TPM and 8.3 g/t silver. Hole MEX-77 was not
completed due to technical problems but was suspended in higher grade
mineralization returning 40 feet of 0.929% copper, 0.269% nickel and 2.379 g/t
TPM including 30 feet of 1.030% copper, 0.294% nickel and 2.690 g/t TPM.
    "The drilling results verify a significant increase in platinum,
palladium and gold numbers as well as strong copper and nickel grades in our
Eastern Area," stated Dr. Henry Sandri, President and CEO. "The four Eastern
holes in this press release continue to demonstrate the higher tenor of the
Eastern Area drill results, in comparison to the overall Nokomis grades.
Marked increased grades in all metals have been, in general, a defining event
of the Eastern Area."
    Two additional holes, MEX 79 and 83, were also completed immediately
south of and along the boundary of the Nokomis Resource Block in the western
area of the property. Highlights include MEX-83 which intersected 105.5 feet
of 0.632% copper, 0.176% nickel and 0.822 g/t TPM including 65.5 feet of
0.742% copper, 0.192% nickel and 0.950 g/t TPM with a 10.0 foot section of
1.020% copper, 0.222% nickel and 1.174 g/t TPM.
    "We are proceeding further with our aggressive 200,000 foot drilling
program to complete-fill and step-out drilling to the existing large Nokomis
Resource Block, and exploration drilling to define new mineralization in the
Eastern Exploration Area," stated Dr. Sandri.
    A "MEX 77-83 Location Map" highlighting these holes can be found on our
Company website at www.duluthmetals.com.
    True thickness is estimated at about 90% of core length. Drill hole
MEX-77 was not completed with drilling suspended in mineralization due to
technical difficulties(*). The following table with (0.3% copper and 0.5% copper
cut-offs) contains a more detailed summary of the drill intercepts:

    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. Large diameter PQ
drilling is also continuing with the objective of providing large bulk sample
material for further metallurgical test work.
