    VANCOUVER, Oct. 27 /CNW/ - Aurizon Mines Ltd. (TSX: ARZ; AMEX:   AZK) is
pleased to provide a progress report on the drilling activities at its Joanna
Gold Project, located 20 kilometres from Rouyn-Noranda, in north-western,
Quebec.
    To date, three hundred ninety-seven (397) holes totalling 118,600 metres
have been completed by Aurizon at Joanna, with the objective of confirming
results from previous drilling and to extend the mineralized zones. Results
from two hundred eighty-two (282) holes have been previously released, and
results from thirty-eight (38) holes are included in this release. Results are
currently pending for seventy-seven (77) holes.
    Drilling completed to date intersected one to three mineralized
intersections along the main zones. Combined and continuous thicknesses
average between 20 and 60 metres for the whole extension of the Hosco Zone
using a cut off grade of 0.5 grams of gold per tonne over 5 metres.
Thicknesses can reach 80 metres locally, plunging steeply to the west.
    "We are pleased to report that the infill drilling program is on schedule
to provide an updated resource model and mineral resource estimate. The total
width of the zone is now defined by a stacking of up to three mineralized
lenses within the proposed pit contour." said Martin Demers, Exploration
Manager of Aurizon.

    
    Results of three (3) typical holes are as follows:

    Results of thirty-five (35) holes with grades above 1 gram of gold per
tonne are indicated on detailed tables attached to this news release. Another
table presents distinct 1.3 to 1.5 metres intervals returning more than
10 grams per tonne. Three (3) of the holes had grades below 1.0 grams of gold
per tonne, and, as a result, were not included in the table. A sketch showing
the location of holes with intersections with grades above 1 gram of gold per
tonne over more than 22 metres, or equivalent metal factor (grade X true
width) is attached to this release.

    
    Hosco Zone
    ----------
    

    Infill drilling is performed on a 25 metre by 25 metre spacing within the
core of the areas previously known as the Hosco Zone as defined by BBA in
their Preliminary Assessment Report dated May 22, 2008, (available under the
Company's profile at www.sedar.com.) In this area, gold mineralization is
located within two lenses located on both sides of the Cadillac break both
dipping 55 degrees to the North. The South Zone, extending for more than
800 metres, corresponds to the entire length of the deposit. The North Zone is
restricted to an extension of 400 metres. All the infill drilling was
successful in intersecting mineralization above cut off parameters defined by
the Preliminary Assessment report.
    The drilling results confirm the continuity of the zones. Historically,
holes drilled by previous owners were only partially assayed for intersections
containing visible veinlets. Recent experience gained by Aurizon indicates
that a more systematic assaying of the drill core can extend the width of the
mineralized zone.

    
    Preliminary Assessment Report
    -----------------------------
    

    The BBA Preliminary Assessment Report concluded that based upon the
September 2007 mineral resources estimate for the East block (Hosco) above the
200 metre level, the project is potentially feasible as a stand alone open-pit
mine operation and recommended that additional work be undertaken to advance
the project to the pre-feasibility stage. In addition, the report provided
guidelines on the environmental risks.
    Based on the preliminary pit optimization studies and mine design in the
report, the diluted in pit resources contained in the detailed pit design
amounts to 9.08 million tonnes in the indicated mineral resource category and
9.07 million tonnes in the inferred mineral resource category at a combined
average grade of 1.5 grams of gold per tonne, based on a cut-off grade of
0.5 grams of gold per tonne. The overall life of mine stripping ratio is
estimated at 3.4 tonnes of waste per tonne of ore, with an inter-ramp pit
slope of 55 degrees. Total metal recovered is estimated at 653,000 ounces of
gold assuming a mill recovery of 77%.
    The Preliminary Assessment Report is preliminary in nature and includes
inferred mineral resources that are considered too speculative geologically to
have the economic considerations applied to them that would enable them to be
categorized as mineral reserves. There is no certainty that the preliminary
assessment will be realized.

    Outlook

    Based on current results, the infill drilling program has been extended
and is now expected to be completed, later in the fourth quarter, 2008.
Aurizon expects to receive an updated resource estimate on the Joanna Gold
Project early in 2009, and has appointed BBA to prepare the pre-feasibility
study upon completion of the updated resource estimate. Roche Ltd. has been
appointed to complete the required environmental studies. The pre-feasibility
study will include the results of the expanded drill program, resource
modelling and the metallurgical testwork that is presently in progress.
    The completion of the infill drilling program is an important element in
the preparation of the pre-feasibility study. Following the infill drilling
program, Aurizon intends to resume its exploration drilling activities,
testing the dip extension below 700 metres, and geophysical and geochemical
targets outside of the main orebody, including the recently optioned
Alexandria property located along the eastern extension of the Joanna deposit.

    Quality Control

    Core assays are performed on core sawed in half, with standard fire assay
procedures and atomic absorption finition. Certified reference material,
duplicate and blanks are inserted in the sample sequence for quality control.
Assay checking on pulp and coarse reject are carried out on approximately 10%
of samples. For additional information on Quality Assurance and Quality
control ("QA/QC"), refer to the previously mentioned Preliminary Assessment
Report. Exploration primary assaying was performed at ALS Chemex of Val d'Or
and check assays were carried out by Laboratoire d'Analyse Bourlamaque of Val
d'Or. ALS Chemex is a fully accredited laboratory under ISO 9001-2000
standards, and Laboratoire d'Analyse Bourlamaque is in the process of
obtaining ISO-9001-2000 certification.
    Drill hole planning, implementation and the quality control program is
supervised by Martin Demers P.Geo., Exploration manager, an appropriately
qualified person as defined by National Instrument 43-101. Mr. Demers is also
responsible for the scientific and technical information in this news release.

    CAUTIONARY NOTE TO US READERS

    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.
