    (1) Mineral resources which are not mineral reserves do not have
        demonstrated economic viability.

        Mineral reserves and resources estimates have been completed in
        accordance with the Standards of Disclosure for Mineral Projects as
        defined by National Instrument 43-101. Mineral resources are
        exclusive of mineral reserves.

        Mineral reserves and mineral resources for 2009 were calculated using
        a gold price of US$825 per ounce.
    

"For the third consecutive year, Casa Berardi has successfully renewed mineral reserves through the conversion of mineral resources." said David Hall, President and CEO. "As previously announced in recent press releases, the extensive drill program, initiated in the second half of 2009, is producing encouraging results and we anticipate a significant upgrade in the quality of our mineral resources plus a positive impact on our mineral reserves at the end of the current year."

    
    Casa Berardi Mine
    -----------------
    

The Casa Berardi gold deposits are located along a five kilometre east-west mineralized corridor. They include the East and West mines, and the Principal Zone. The Casa Berardi gold deposits can be classified as an Archean sedimentary-hosted lode gold deposit. The gold mineralization is superimposed on a continuous graphitic mudrock unit corresponding to the Casa Berardi Fault plane. Gold occurs mainly south of the Casa Berardi Fault, and sometimes on both sides of the fault.

The mine has produced 1.2 million recovered gold ounces since commencing production in 1986, including 495,300 recovered ounces since Aurizon recommenced production in December 2006.

Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) were commissioned by Aurizon to prepare updated mineral reserve and mineral resource estimates on the different zones of the property.

    Notes:

    1.  CIM definitions were followed for Mineral Reserves.
    2.  Mineral Reserves are estimated at a cut-off grade of 3.9 g/t Au for
        underground, and 1.2 g/t Au for open pit.
    3.  Mineral Reserves are estimated using an average long-term gold price
        of US$825 per ounce and a US$/C$ exchange rate of 1:1.09.
    4.  A minimum mining width of three metres was used.
    5.  Totals may not represent the sum of the parts due to rounding.
    6.  See Appendix A for additional technical parameters.
    

Proven and Probable Mineral Reserves have increased as a result of:

    
    -   At the West Mine, the 2009 mine production in Zones 113, Lower Inter
        and North West have been offset by the gain in mineral reserves from
        Zones 115, 118 and Lower Inter.

    -   A 9% decrease in grade is a result of the addition of lower grade ore
        from the Zone 113, 118 and Lower Inter and a decrease in the cut-off
        grade, due to higher gold prices.

    -   Mineral reserves are estimated using an average long-term gold price
        of US$825 per ounce, compared to US$750 per ounce in 2008, and a
        US$/C$ exchange of 1:1.09. A minimum cut off grade of 3.9 grams of
        gold per tonne was used, based on long term operating costs and gold
        prices, for the underground zones; and 1.2 grams of gold per tonne
        for the open pit. In 2008, the minimum cut off grade was 4.4 grams of
        gold per tonne.

    -   As the mining industry is currently experiencing gold prices that are
        higher than US$825 per ounce, the operations periodically mine ore
        that is not included in mineral reserves as the grades are lower than
        the minimum cut-off grades.

    Reconciliation of Casa Berardi Mineral Reserves
    -----------------------------------------------
    

Reconciliations of the mineral reserve estimates to the 2009 mill production return 105% for the tonnage, 97% for the grade and 101% for the ounces.

    Mineral Reserves - December 31, 2008          3,836,000          956,000
    Resource conversion(1)                        1,078,000          200,000

    Mineral Reserves - December 31, 2009          4,433,000        1,010,000
    -------------------------------------------------------------------------

    (1) Resource conversion resulted in the addition of 200,000 ounces to
        mineral reserves.

    (2) Mining depletion represents mineral reserves mined and processed in
        2009 before milling recoveries and excludes 7,000 ounces mined
        outside of the reserves established at the beginning of the year and,
        therefore, does not correspond to the actual 2009 gold production of
        159,261 ounces.

    (3) Mining costs represent an adjustment to the cut-off grade due to an
        increase in the three year moving average gold price and stable
        operating costs.

    Mine Plan for Mineral Reserves
    ------------------------------

    -   The mine plan for the current mineral reserves totals 4.4 million
        tonnes of ore, grading 7.09 grams of gold per tonne, to be mined over
        six years (2010 to 2016) from the 113 Zone, Lower Inter Zone, 118
        Zone and six smaller West Mine zones, as well as the open pit and
        underground production from the East Mine.

    -   Development was compiled by zone, measured from mine plans, and
        scheduled monthly for 2010, and quarterly thereafter. Development
        requirements average 25 metres per day for the next three years, and
        then decline rapidly, as most accesses and infrastructure will be
        completed.

    -   Production was compiled by stope, and scheduled quarterly by zone.
        The majority of the production tonnage will come from the 113, Lower
        Inter and the 118 Zones, together making up 72% of underground
        reserves.

    Notes:

    1.  CIM definitions were followed for Mineral Resources.
    2.  Mineral Resources are estimated at cut-off grades of:
        -  4 g/t Au for West Mine, Principal Mine and East Mine.
        -  3 g/t Au for South West, Inter and 104 zones in the West Mine.
           Those zones were estimated by Aurizon in 2000 using 2D polygons on
           longitudinal sections and reviewed by RPA in 2005.
        -  1.30 g/t Au for the East Mine - Open Pit (Geostat, 2008).
    3.  Mineral Resources are estimated using an average long-term gold price
        of US$825 per ounce, and a US$/C$ exchange rate of 1:1.09.
    4.  Minimum mining widths of two to three metres were used.
    5.  Mineral Resources are exclusive of Mineral Reserves.
    6.  Totals may not represent the sum of the parts due to rounding.
    7.  Mineral resources which are not mineral reserves do not have
        demonstrated economic viability
    8.  See Appendix B for additional technical parameters.

    Comparison with 2008 Mineral Resources
    --------------------------------------
    

The main variance in the mineral resource estimates between 2009 and 2008 are as follows:

    
    -   Geological re-interpretation of mineralized zones after drilling
        programs (Zone 113, 115, 118 and Lower Inter).

    -   Geological interpretation and 3D block model of two new mineralized
        zones (Zones 113 (S4) and 152 (East Mine)).

    -   Conversion of inferred into indicated; or of indicated into measured.

    -   Conversion of mineral resources into mineral reserves.

    -   Conversion of mineral resources to mineral reserves after completion
        of economic mining plan for Zones 115 and 118.

    -   Mining depletion (Zones 113, North West, Lower Inter).

    Outlook
    -------
    

Aurizon intends to utilize its strong cash flow to upgrade mineral resources to mineral reserves in order to extend and optimize the current mine plan.

In 2010, Aurizon also intends to update the mineral resources following an aggressive diamond drilling program and to complete a prefeasibility study to assess the relative risks and opportunities of mining the Principal Zone crown pillar by open pit.

The 810 metre level exploration drift will be extended in early 2010 to provide new access to drill the 113(deep), 113(S4), 118 and 123 Zones. Later this year, the 550 metre level exploration track drift will be extended by 600 metres to provide a drilling platform to verify the continuity between the Principal zones, and the 118, 120 and 123 Zones.

A surface exploration drilling program at both the East and West Mine is evaluating the extension of existing zones and testing new interpolated targets.

CAUTIONARY NOTE TO US READERS AND INVESTORS

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. Readers and 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 mineral 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" mineral 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. readers and 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" mineral 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. readers and investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

    
                                 APPENDIX A
                                 ----------

    Technical Parameters - Mineral Reserve Estimate
    -----------------------------------------------
    

The technical parameters for the mineral reserve estimate are as follows:

    
    -   Mineral reserve estimations were based on 3D block models for all
        zones except the South West Zone; the few remaining zones that were
        estimated using 2D polygonal methods are not included in mineral
        reserves.

    -   For the underground operation, the selected mining method is usually
        Sequential Transversal and Longitudinal Long Hole when the vein is
        larger than 10 metres and Longitudinal Long Hole Retreat when the
        vein is less than 10 metres. The stoping sequence includes cemented
        rockfill of the primary stoping sequence, cemented and unconsolidated
        rockfill for the longitudinal retreat and unconsolidated rockfill for
        secondary stoping sequence.

    -   Stope dilution has been calculated from numerical modeling on the
        basis of the stability of the stope openings, ore deposit geometry
        and mining method. The amount of dilution was reduced for stopes of
        smaller dimensions on the fringes of the zone, and increased for
        stopes with unfavourable geometry. In addition, each stope was
        assigned a backfill dilution percentage based on number of walls of
        fill and type of mucking floor. Dilution quantities were estimated
        for each stope, including hanging wall/footwall sloughage, and
        backfill dilution, where applicable. As a result, the dilution
        averages 21%.

    -   Extraction was estimated at 90% for primary stopes, and 95% for
        secondary stopes.

    -   A minimum cut off grade of 3.9 grams of gold per tonne was used based
        on long term operating cost and gold prices for most of the
        underground zones in the West Mine. For the East Mine crown pillar, a
        minimum cut off grade of 1.2 grams of gold per tonne was used based
        on long term operating costs and gold prices.

    -   Bulk density is different for each zone and is based on density
        determinations. Bulk density varies from 2.70 tonne per cubic metre
        (e.g. Zone 113) to 2.90 tonne per cubic metre (e.g. Principal Zones).
        A bulk density of 2.77 tonne per cubic metre was used for zones that
        have no density determinations (e.g. East Mine) and is based on
        historical data.

    -   Mineral reserves are estimated using an average long-term gold price
        of US$825 per ounce and a US$/C$ exchange rate of 1:1.09.

    -   Minimum underground mining widths of three metres were used.

    -   West Mine mineral reserves are based on new information acquired from
        the definition drilling completed in 2009. Information from the
        definition drilling is being used to outline the precise ore stope
        dimensions. Footwall drifts, which are set 20 metres apart, are being
        used as the collar locations of the current drill program.

    -   East Mine open pit reserves are contained in the crown pillar left
        behind by previous mining. Open pit optimization and detailed design
        were updated in 2008. A dilution factor of 20% was applied to open
        pit mineralization within the pit design, and above the 1.2 grams of
        gold per tonne cut-off grade. It is anticipated that the East mine
        crown pillar open pit will have a depth of 80 metres. The zone is
        covered by 18 metres of silt and clay overburden. Stripping ratio is
        estimated at 17:1.

    -   The East Mine underground reserves are based on a plan to re-
        establish access to old workings, and mine pillars and levels left
        behind during previous operations. Stope sizes are not standardized.
        Mining methods include longhole stoping where access can be attained
        for both top and bottom cuts, and cut and fill methods where only
        undercuts are accessible.


                                 Appendix B

    Technical Parameters - Mineral Resource Estimate
    ------------------------------------------------
    

The technical parameters for the mineral resource estimate are as follows:

    
    -   Except for the Inter and South-West zones, which are 2D polygonal
        estimates, and for the East Mine Crown Pillar, the resource estimates
        of the different mineralized zones at Casa Berardi since October 2005
        have been calculated by the use of block modeling grade interpolation
        by Scott Wilson RPA, assisted by mine staff.

    -   Mineral resources are estimated using an average long-term gold price
        of US$825 per ounce, and a US$/C$ exchange of 1:1.09.

    -   Grade estimation was usually carried out from 3D block solids. Drill
        holes as well as development samples were used for grade
        interpolation. Smaller zones were estimated previously by Aurizon,
        using 2D polygonal on longitudinal sections and have been reviewed by
        Scott Wilson RPA.

    -   Different minimum cut off grades were used as follows:

        -  4.0 grams of gold per tonne was used based on long term operating
           cost and gold prices for most of the underground zones in the West
           Mine, for the Principal Zone and the underground East Mine.

        -  4.3 grams of gold per tonne was historically used for the Cherty
           and 160E Zones.

        -  3.0 grams of gold per tonne was used for small zones previously
           estimated by 2D polygons on longitudinal sections.

        -  1.3 grams of gold per tonne was used based on long term operating
           cost and gold prices for most the open pit crown pillar at the
           East Mine.

        -  0.8 grams of gold per tonne was used based on long term operating
           costs and gold prices for the crown pillar at the Principal Mine.

    -   A total of 25 mineralized zones have been modeled at the Principal
        Zone. As the mineralized system extends towards the overburden-rock
        interface and the mineralized zones are close enough to each other to
        envisage open pit mining, the zones were modeled by using a 1.0 grams
        of gold per tonne threshold. The current block size is 1.25 metres
        north-south by 2.5 metres east-west by 5.0 metres vertical. The
        Principal Zone is covered by approximately 45 metres of overburden,
        which is composed of a thin layer of peat and thicker horizons of
        silt and glacial till. The host rock is of volcanic and sedimentary
        origin.

    -   Overall pit slopes of 24 degrees  and 55 degrees  were used for the
        overburden and host rock, respectively.

    -   Bulk density is different for each zone and is based on density
        determinations. Bulk density varies from 2.70 tonne per cubic metre
        (e.g. Zone 113) to 2.90 tonne per cubic metre (e.g. Principal Zones).
        A bulk density of 2.77 tonne per cubic metre was used for zones that
        have no density determinations (e.g. East Mine) and is based on
        historical data.

    -   Minimum underground mining widths of two to three metres.
