MacDonald Mines Outlines Targets on 5 Distinct Project Areas; 5000 Metre Drill Program to Commence in Late June



    TORONTO, June 16 /CNW/ - MacDonald Mines Exploration Ltd. (TSX
VENTURE:BMK) ("MacDonald" or the "Company") is pleased to announce it will
commence it's Spring 2008 drill program in late June, covering targets on five
project areas in the "Ring of Fire" District of the James Bay Lowlands. The
drill program will operate through to the end of October 2008.

    Drill Program

    Approximately 30 holes, totaling 5,000 metres will be diamond-drilled
within five of the Company's project areas, where each individual project area
represents a separate property within MacDonald Mines' extensive land
position. The five properties are made up of distinct but separate claim
groups distributed over a wide geographical area that is underlain by similar
geology.

    The Five Project Areas

    The drill program will focus on geophysically defined targets on the
following five Project Areas;

    
    1.  McNugget Property    (100% MacDonald owned, including 6 claim Hawk
                             Uranium JV Property)
    2.  Salo Property        (100% MacDonald owned)
    3.  Wellington Property  (MacDonald, Canadian Orebodies, Coordinates
                             Capital Corp.)
    4.  Adelaide Property    (MacDonald, Temex, Canadian Orebodies)
    5.  Hornby Property      (MacDonald and Temex)
    

    Description of Targets

    Hadyn Butler, P.Geo. Director and Chief Geologist for MacDonald Mines
commented,
    "MacDonald's recently completed James Bay Lowlands airborne geophysical
surveys have located both "Distinctive coincident magnetic-electromagnetic
targets, as well as long stratigraphic conductors." Multiple discrete (short
strike length) coincident magnetic-electromagnetic targets have been found on
all Project Areas and show similar discrete magnetic-electromagnetic
signatures known to be associated with the Noront Double Eagle
nickel-copper-platinum-group-element ("Ni-Cu-PGE") sulphide deposit, where the
magnetic component is mostly pyrrhotite. The geophysical target strike length
is often short-forming discrete magnetic and electromagnetic surface anomalies
with the long axis of mineralization (due to tectonic stretching) towards the
vertical. Geophysical target discreteness of this kind is a known part of the
Archean tectonic pattern, which is now beginning to present themselves in the
James Bay Lowlands "Ring of Fire".
    MacDonald's on-going ground geophysical surveys have defined prime
geophysical target positions, as outlined, in preparation for the upcoming
diamond drilling campaign."
    The Spider-KWG McFaulds discovery, which included 8.02% copper over
18.8 metres from hole MCF 04-57, and the very recent WSR VMS discovery, which
included 131.9 metres of semi-massive to near massive sulphides in Hole
5.01-09, outlines the features of the volcanogenic massive sulphide ("VMS")
deposits in the area, where the magnetic component is mostly magnetite in the
VMS feeder zone.
    Hadyn Butler, further commenting on the evolving geological description
of the James Bay Lowlands, stated the following;

    
    -   To this time, exploration drilling results of formational conductors
        in the "Ring of Fire" regional greenstones have been identified as
        sulphidic.
    -   Many large well-differentiated gabbro chambers containing lower
        ultramafic (peridotite and pyroxenite) and chromitite layers, as well
        as upper titanomagnetite layers, occur near the base of the regional
        greenstone succession.
    -   The volcanic covering above these gabbro chambers contain significant
        VMS deposits and laterally extensive sulphidic units, some with a
        signature suggesting VMS stratigraphic horizons akin to the "Key-
        Tuffite horizon" in the Matagami VMS Camp in Quebec.
    -   The gabbros themselves likely provided the "heat engine" that created
        the VMS deposits in the volcanic successions above.
    -   In this greenstone succession, the basal layer of the gabbro chambers
        is the target horizon for Ni-Cu-PGE mineralization.
    -   MacDonald has several discrete geophysical targets in this same
        stratigraphic position, and probable repeat sequences (folded and/or
        faulted) farther south, east and west of the greenstone base layer.
    -   Early drilling campaigns proved that MacDonald has a number of VMS
        target horizons.
