UEX/AREVA Report Additional High-Grade Basement-Hosted Mineralization in the Prospective Corridor Between the Kianna and Anne Deposits: SHE-121-3 Intersects 1.57% U(3)O(8) Over 3.7 metres



    Trading Symbol: UEX-TSX

    VANCOUVER, Dec. 4 /CNW/ - UEX Corporation ("UEX") announced today that
AREVA Group subsidiary AREVA Resources Canada Inc. ("AREVA") has reported to
UEX the last holes from the 2007 fall drilling program at its Shea Creek
Uranium Project ("Shea Creek"), which is located in the western Athabasca
Basin of northern Saskatchewan, Canada.
    Shea Creek hosts the Kianna, Anne, and Colette Deposits and is one of the
ten Western Athabasca Projects currently under option from AREVA, the
operator. UEX has earned a 40.0% interest in the ten projects and has spent in
excess of $27.8 million on exploration and development expenditures in just
over three years, as of October 31, 2007. UEX has an option to earn an
additional 9% interest, and anticipates that it will reach the required
expenditures of $30.0 million to earn its full 49% interest by December 31,
2007, at which time, AREVA and UEX will form a Joint Venture where
expenditures will be shared 49% by UEX and 51% by AREVA.
    "We recently announced in this fall program SHE-123-2 grading 2.80%
U(3)O(8) over 4.9 metres 150 metres south of Kianna and now SHE-121-3 grading
1.57% U(3)O(8) over 3.7 metres 225 metres north of Anne. Both holes
intersected new high-grade basement-hosted structures in the prospective
corridor between the two deposits. Whether the mineralization in these holes
is directly associated with Anne and Kianna or are two of potentially several
interconnected mineralized structures interpreted along the 600 metre strike
between Anne and Kianna will be determined by further drilling," said Stephen
Sorensen President and CEO of UEX.
    Sorensen went on to say that "the Shea Creek Corridor has the potential
to be mineralized over the entire three kilometre strike length between the
Anne, Kianna and Colette Deposits. The fall exploration campaign was very
successful with all holes intersecting mineralization within one or more
settings, either perched, unconformity or basement mineralization. The
directional cuts that successfully intersected mineralization which is
reported here between Anne and Kianna will permit continued drilling aimed at
intersecting these and any additional mineralized structures. Such structures
have the potential to contain basement hosted mineralization comparable to
that in the Anne and Kianna deposits, which include intersections such as in
SHE-114-11 where 5.40% U(3)O(8) was intersected over 37.7 metres at Kianna,
and in SHE-122-1 where 4.73% U(3)O(8) was intersected over 33.7 metres at
Anne."

    2007 Fall Drilling Program at the Shea Creek Project

    The 2007 fall drilling program utilized three drills that started in
mid-September is now completed. One drill was used to expand the Anne Deposit;
currently the Anne Deposit is open in all directions. Pilot hole SHE-122
completed during the summer months (see Map 1 on UEX's website), was being
used to test the unconformity ("UC") and basement ("B") extensions of
mineralization in the northern portion of the Anne Deposit. With the discovery
of high-grade basement mineralization in the Kianna Deposit, a greater focus
is being placed on the basement mineralization at the Anne Deposit.
    Another two drills were used to explore the area between the Kianna and
Anne Deposits, where historical drilling intersected mineralization in 9 out
of 13 drill holes. The two deposits are about 600 metres apart. Drilling
utilized pilot holes SHE-121 and SHE-123 (see Map 2) to target inferred
structures that offset a favourable geological trend between the Anne and
Kianna Deposits. Structural offsets are considered important for uranium
deposition and are recognized in all three deposits at Shea Creek.

    Drilling Between the Anne and Kianna Deposits:

    
    SHE-121-3:
    (UC) 0.39% U(3)O(8) over 2.8 metres
    (B)  1.57% U(3)O(8) over 3.7 metres, including 2.05% U(3)O(8) over
         2.8 metres
    (B)  0.22% U(3)O(8) over 2.0 metres
    

    SHE-121-3 is located between the Anne and Kianna deposits. The hole
location is 225 metres north of the Anne Deposit. The purpose of the hole was
to extend upon the unconformity mineralization in SHE-121-2 (reported on
November 14, 2007) and to identify possible basement structures. The
unconformity was intersected 65 metres north-east of pilot hole SHE-121 at a
depth of 727.8 metres. The majority of the mineralization at the unconformity
was associated with breccias between 725.3 to 728.1 metres grading 0.39%
U(3)O(8) over 2.8 metres. High-grade basement-hosted mineralization was
encountered between 750.8 to 754.5 metres grading 1.57% U(3)O(8) over 3.7
metres, including 2.05% U(3)O(8) over 2.8 metres. A second zone in the
basement was encountered between 770.8 to 772.8 metres grading 0.22% U(3)O(8)
over 2.0 metres.
    The significance of the unconformity mineralization with previous
released results this fall has uncovered a mineralized strike length of
90 metres that remains open in all directions. In addition, multiple
intersections of basement-hosted mineralization within structures warrants
additional drilling.

    Anne Deposit Drilling:

    
    SHE-122-3:
    (UC) 0.65% U(3)O(8) over 3.5 metres
    (B)  1.08% U(3)O(8) over 1.6 metres
    (B)  3.50% U(3)O(8) over 1.6 metres
    (B)  0.65% U(3)O(8) over 2.0 metres
    

    SHE-122-3 is located on the western side of the Anne Deposit. The purpose
of the hole was to extend upon the unconformity mineralization and expanding
the potential for high grade basement mineralization. The unconformity was
intersected 45 metres north of pilot hole SHE-122 at a depth of 726.8 metres.
Mineralization was associated with breccias at the unconformity between 723.4
to 726.9 metres grading 0.65% U(3)O(8) over 3.5 metres. High-grade
basement-hosted mineralization was encountered between 738.4 to 740.0 metres
grading 1.08% U(3)O(8) over 1.6 metres. A second zone of high-grade
basement-hosted mineralization was encountered between 773.0 to 774.6 metres
grading 3.50% U(3)O(8) over 1.6 metres. An additional zone of mineralization
was encountered in the basement between 786.8 to 788.8 metres grading 0.65%
U(3)O(8) over 2.0 metres.
    The mineralization at the unconformity and within the basement in the
northern portion of the Anne Deposit (the Anne Deposit has a strike length
greater than 250 metres) is still open in all directions.
    Uranium grades are calculated from gamma probe logging. True widths of
mineralized intervals have not yet been determined. The technical information
in this news release has been compiled and reviewed by Erwin Koning, P. Geo.,
AREVA's District Geologist, West Athabasca Region, a qualified person as
defined by National Instrument 43-101.

    About the Anne Deposit

    The Anne Deposit is geologically comparable to the Kianna Deposit with
both unconformity and basement mineralization. To date, the unconformity
mineralization at the Anne Deposit has been traced over a strike length of
250 metres and a width of 100 metres and remains open in all directions. With
the recent focus on the Kianna Deposit, no work has been carried out on the
Anne Deposit since the fall of 2004.

    
    Previous drilling programs have outlined three distinct styles of
high-grade mineralization:

    -   Unconformity-type mineralization in close proximity to the
        unconformity (previous hole SHE-99-2, grading 9.17% U(3)O(8) over
        15.7 metres, including 36.37% U(3)O(8) over 2.5 metres);
    -   Basement-hosted mineralization found in zones up to 35 metres below
        the unconformity: (previous hole SHE-96-3, grading 1.39% U(3)O(8)
        over 47.3 metres).
    -   Fracture/fault controlled perched mineralization higher in the
        sandstone column is also prevalent within the Anne area. However,
        intersections can not be correlated between drill holes with the
        current density of drill information
    

    About the Kianna Deposit

    At the Kianna Deposit, high-grade uranium mineralization has been
intersected in multiple zones at depths from 662 metres to 922 metres, a
vertical distance of approximately 260 metres - located in sandstone high
above the unconformity, at the unconformity, and below the unconformity in
basement rocks, with unconformity depths ranging from approximately 710 to
760 metres.

    
    To date, the AREVA-UEX drilling programs from 2004 through to 2007 have
outlined three distinct styles of high-grade uranium mineralization that are
still open in all directions:

    -   Perched sandstone-hosted mineralization found in discrete zones tens
        of metres above the unconformity currently has a defined strike
        length of 80 metres and a width of 60 metres (previously announced
        2005 hole SHE-114-5, 27.4% U(3)O(8) over 8.8 metres, including
        58.3% U(3)O(8) over 3.5 metres);
    -   Unconformity-type mineralization in close proximity to the
        unconformity has a defined strike length of 200 metres and a width of
        200 metres (previously announced 2006 hole SHE-115-3, grading 12.57%
        U(3)O(8) over 11.9 metres, including 27.35% U(3)O(8) over
        4.2 metres);
    -   Basement-hosted mineralization found in zones up to 200 metres below
        the unconformity has outlined a strike length of 200 metres and a
        down-dip extension of 160 metres (previously announced 2005 hole
        SHE-114-11, grading 5.40% U(3)O(8) over 37.7 metres, including
        25.46% U(3)O(8) over 4.0 metres).
