Duluth Metals receives scoping level metallurgical study and updates metallurgical program



    TORONTO, Nov. 19 /CNW/ - Duluth Metals Limited ("Duluth") (TSX: DM)
(TSX:DM.U) today announced the receipt of a report entitled "A PRELIMINARY
REPORT OF A SCOPING LEVEL METALLURGICAL STUDY CONDUCTED ON THE CU/NI/PGM
NOKOMIS DEPOSIT" completed by SGS Lakefield Research Ltd., a Member of the SGS
Group (SGS SA). The report is available on our website at
www.duluthmetals.com.
    A scoping level metallurgical study was conducted for Duluth Metals Ltd
on a 252 kg composite ore sample of drill core from the Maturi Extension
Properties - Nokomis Deposit. The composite was taken from 8 widely spaced
holes, and graded 0.75% Cu, 0.24% Ni, 0.19 g/t Pt, 0.43 g/t Pd and 0.12 g/t
Au. Significant high extraction and recovery rates were returned from the
initial metallurgical test of the Nokomis Deposit copper - nickel - PGM ores
as outlined below. These results confirm the use of conventional flotation -
concentration and hydrometallurgical processing using the Platsol(TM) process
as the preferred method of final recovery. The Nokomis Deposit occupies
approximately one third of Duluth's Maturi Extension Properties near Ely,
Minnesota.
    "The full results of the report confirmed the superb recoveries of
copper, nickel and PGMs and presented a number of areas where improvements may
further enhance recoveries" stated Dr. Henry Sandri, President and CEO. "The
Nokomis ore was tested using a wide range of processing techniques. Multiple
hydrometallurgical tests were also conducted, resulting in the highest
recoveries using Platsol(TM) which allows for an environmentally clean method
of recovering base and precious metals. These recoveries are some of the
highest seen to date with Duluth Complex ores. While the current results are
excellent, we plan to undertake more testing to continue to optimize our
approach and flowsheet".

    
    The Metallurgical Study reported the following results:

    -   Multiple flotation-concentration tests and hydrometallurgical tests
        were performed in order to design an appropriate flowsheet for
        processing Nokomis deposit ore.

    -   Flotation-Concentration Recoveries of 95.3% for copper and 72.4% for
        nickel, and 86.0%, 87.0% and 73.0% for platinum, palladium and gold,
        respectively, producing a bulk Cu-Ni concentrate were achieved using
        conventional flotation-concentration techniques.

    -   Hydrometallurgical testing using the Platsol(TM) process on the bulk
        Cu-Ni concentrate produced extraction efficiencies of 99.6%, 99.2%,
        97.6%, 98.1%, and 84.1%, respectively for Cu, Ni, Pt, Pd and Au under
        typical Platsol(TM) conditions.

    -   Combined Flotation-Concentration and Platsol(TM) testing achieved
        recoveries of 94.9% for copper and 71.8% for nickel, and 83.9%, 85.4%
        and 61.3% for platinum, palladium and gold, respectively.

    -   Split stream tests also showed very good initial promise at producing
        a separate saleable Cu concentrate, grading 28% Cu, 1% Ni, 2.38 g/t
        Pt, 9.24 g/t Pd and 3.38 g/t Au, and a commercial bulk nickel
        concentrate.
    

    Results of these tests will be input into Duluth's Scoping Study of the
Nokomis Deposit, presently being prepared by Scott Wilson Roscoe Postle
Associates Inc.
    Duluth is presently preparing a second set of samples for further testing
and optimization studies at SGS Lakefield. This round will utilize the core
reject from 12 selected holes in the Nokomis Deposit. Two-hundred to
three-hundred kg composite samples are being batched from the reject, with
sufficient sample remaining to test individual holes. The suite of samples
will yield approximately 1,230 kg of material for testing and attempt to:
cover all geographic quarters of the Nokomis Deposit, represent a spectrum of
grades and mineralogies, and cover the various metals ratios.
    Duluth has also initiated a large core drilling program using PQ (3.35
inch) sized drill core. Duluth is presently drilling with 5 drill rigs, 4
drilling NQ (1.875 inch) core and 1 drilling PQ. During the winter/spring of
2007-2008, two more of the drills will convert to PQ drilling. Duluth plans to
drill 12 to 16 sites, each site drilling 4 to 5 holes, in its current +200,000
foot drill program using PQ drills in order to obtain 30 tonnes of samples for
further metallurgical testing. This testing will include crushing and grinding
tests to determine the representative Bond mill work index and a bulk sample
bench scale test optimizing the flotation-concentration and hydrometallurgical
processing flowsheet. This data will be used in Duluth's 2008 Pre-Feasibility
Study.

    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.
