    VANCOUVER, Nov. 8 /CNW/ - Aurizon Mines Ltd. (TSX:ARZ)(AMEX:  AZK) is
pleased to report results from its 2007 surface exploration program, at its
100 percent owned Kipawa Gold-Uranium project, north-western Quebec, Canada.
    The Kipawa area is located approximately 100 kilometres south of
Rouyn-Noranda, along the provincial border, and is accessible via logging
roads. The project covers a strike length of 75 kilometres, halfway between
the Elliot Lake uranium camp and the Abitibi gold belt camp, within the
Grenville Front, surrounding the alkaline Kipawa complex.
    Extensive field prospecting was conducted during this summer, as a follow
up to the 2006 till sampling results, which returned grades of up to 100 grams
of gold per tonne, (see Aurizon's news release dated February 26, 2007).

    -   Induced Polarization surveys and systematic till sampling of outcrops
        surrounding the gold dispersion trains, were conducted during the
        summer, 2007. There were 260 additional till samples taken within an
        area of 660 square kilometres. Assays are pending and should be
        released by year end.

    -   Uranium, rare earth element minerals and gold clustered anomalies
        associated with airborne radiometric anomalies, were discovered
        within two main areas referred to as Snake and Eagle. The best
        results are as follows:

                                              Light Rare      Heavy Rare
    Area (Sample)     U3O8     Yttrium       Earth Element   Earth Element
    Snake (63884)     0.20%     0.67%            0.09%           0.30%
    Eagle (63590)       -       0.32%            5.34%            0.4%

    "Rare earth and uranium discoveries, associated with the gold potential
at Kipawa, open up new exploration opportunities for Aurizon, considering that
these elements could provide the new solution to future global energy and
environmental challenges," said Martin Demers, Exploration Manager.


    A preliminary ground radiometric survey, using a SAIC GR-135 gamma-ray
spectrometer, was performed over a 350 square kilometre area along existing
road access, where anomalies were identified by airborne radiometric surveys.
    More than six hundred (600) measurements were taken and seven areas
returned continuous readings averaging between 611 to 24,060 counts per minute
on the Snake area.
    Uranophane, an alteration uranium bearing mineral, was observed on the
outcrop returning the best radiometric anomalies. Three hundred and fifty
(350) samples were taken, of which assays from 310 samples have been received
to date. The best assays from the grab samples returned a value of 0.20% U3O8.

    The main uranium anomalies were located within a metasedimentary belt
intruded by alkaline intrusions and were not associated with pegmatite dykes.
All of the area is affected by a large flat dipping shear zone delineating a
major contact between two geological provinces of Proterozoic and Archean age.
The main area also seems to be closely associated with later brittle northwest
trending structural fractures.
    More specifically, each anomaly was located along a multi-metres wide
straight layered paragneiss, where favourable reducing agents such as
magnetite, amphibole, molybdenite, biotite, pyrite concentrations associated
with and without graphite, are present. At this stage the dimension of the
favourable horizons remains unknown.
    The best uranium assays are associated with thorium values which are
above the laboratory's detection limit and will be reanalyzed. Considering the
potentially negative impact of thorium on future metallurgical recoveries of
uranium, a mineralogical study including microprobe analysis will be
undertaken to characterize the ore-bearing minerals.

    Rare Earth Elements

    Following the radiometric survey, prospecting found rare earth elements
mineralization associated with the oxide rich layers. The rare earth elements
typically occur in an alkaline intrusive context, such as the Kipawa complex.

    (1) Light rare earth elements include lanthanium (La), cerium (Ce),
        praseodymium (Pr) and neodymium (Nd).
    (2) Heavy rare earth elements include promethium (Pm), samarium (Sm),
        europium (Eu), gadolinium (Gd),  terbium (Tb), dysprosium (Dy),
        holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb) and
        lutetium (Lu).
    (3) Promethiums have not been assayed.

    Rare earth element anomalies are also associated with gallium, zirconium,
and yttrium.

    The principal uses of rare earth elements are:

    -   Petroleum fluid cracking catalysts
    -   Metallurgical applications
    -   Glass polishing compounds
    -   Glass additives
    -   Permanent magnets
    -   Catalytic converter materials
    -   Television, lighting, and X-ray intensifying phosphors
    -   The diverse nuclear, metallurgical, chemical, catalytic, electrical,
        magnetic, and optical properties of the rare earth elements have led
        to an ever increasing variety of applications. These uses range from
        mundane (lighter flints, glass polishing) to high-tech (phosphors,
        lasers, magnets, batteries, magnetic refrigeration) to futuristic
        (high-temperature superconductivity, safe storage and transport of
        hydrogen for a post-hydrocarbon economy).

    Light rare earth elements are used in the energy and high technology
industries as metal or oxide. Generally, assays for these elements average
below 2%. One sample, taken from Kipawa, returned assays over 2%.
    Heavy rare earth elements are used in high-technology and scientific
research industries, as composite material. Generally, assays for these
elements average below 0.02%. Fourteen (14) samples of the forty two samples
(42) taken from Kipawa, returned assays above 0.02%.
    Preliminary assays and the mineralogical context suggest a favourable
rare earth element discovery within the Kipawa complex.


    In 2008, Aurizon intends to aggressively resume its exploration effort in
the area, with gold, uranium and rare earth elements as primary targets.
Trenching and drilling will be performed as soon as the appropriate permits
and approvals are obtained.
    A progress report on Aurizon's 2007 gold exploration activities at Kipawa
will be released shortly.
    Aurizon has continuously worked in close collaboration with the First
Nation communities of Eagle Village and Wolf Lake over the last two years.

    Qualified Person and Quality Control

    Assays were performed on grab samples, averaging two kilograms.
Determination of uranium and Rare Earth Elements were conducted with lithium
metaborate fusion while gold assays were performed with standard fire assay.
Both were followed by standard ion couple plasma mass spectrometry assays,
Certified reference materials and blanks are inserted in the sample sequence
for quality control. Assay checking on the pulp and reject samples are carried
out systematically. Exploration primary assaying is performed at ALS Chemex,
located in Val-d'Or, Quebec.

    As a British Columbia corporation, the Company is subject to certain
rules and regulations issued by the British Columbia Securities Commission
("BC Securities Commission"). The Company is required to provide detailed
information regarding its properties including mineralization, drilling,
sampling and analysis, security of samples and mineral resource and mineral
reserve estimates. Further, the Company describes mineral resources associated
with its properties utilizing terminology such as "indicated" or "inferred"
which terms are recognized by Canadian regulations but are not recognized by
the United States Securities and Exchange Commission ("SEC").

    Cautionary Note to U.S. Investors Regarding Mineral Resources

    The SEC allows mining companies, in their filings with the SEC, to
disclose only those mineral deposits they can economically and legally extract
or produce. The Company may use certain terms in this document, such as
"mineral resources", "indicated mineral resources" and "inferred resources"
that are recognized and mandated by Canadian securities regulators but are not
recognized by the SEC.

    This News Release may use the term "indicated" resources. U.S. readers
are cautioned that while that term is recognized and required by Canadian
regulations, the SEC does not recognize it. U.S. investors are cautioned not
to assume that any part or all of mineral deposits in this category will ever
be converted into mineral reserves.

    This News Release may also use the term "inferred" resources. U.S.
readers are cautioned that while this term is recognized and required by
Canadian regulations, the SEC does not recognize it. "Inferred resources" have
a great amount of uncertainty as to their existence, and great uncertainty as
to their economic and legal feasibility. It cannot be assumed that all or any
part of an Inferred Mineral Resource will ever be upgraded to a higher
category. Under Canadian rules, estimates of Inferred Mineral Resources may
not form the basis of feasibility or pre-feasibility studies, except in rare
cases. U.S. investors are cautioned not to assume that part or all of an
inferred resource exists, or is economically or legally mineable.
