Canadian Arrow Mines Upgrades Kenbridge Nickel Resource Estimate - 87% Increase in Nickel Contained in Measured and Indicated Classes

    SUDBURY, ON, Aug. 19 /CNW/ - Canadian Arrow Mines Ltd. (CRO: TSX-V) (the
"Company") is pleased to report an updated and upgraded resource estimate for
the Kenbridge Nickel Project in northwest Ontario. The updated resource model
was derived from an extensive database containing 62,487 metres of underground
and surface diamond drilling, including delineation drilling conducted during
the latter half of the 2007-2008 drill program that focused primarily on
mineralization below the limits of the proposed open pit. The tighter drill
definition has also upgraded the majority if the resource from inferred to
measured and indicated classifications. The model extends from surface to a
vertical depth of 725 m. Mineralization remains open below this depth and
along strike.
    The table below summarizes the upgraded Kenbridge resource estimate:

    (1) The updated resource for Kenbridge is estimated on the basis of US$
        metal prices of $10.00/lb nickel, $2.50/lb copper, $25/lb cobalt with
        a USD exchange rate of $0.90. NSR cut-offs were $13/tonne for open
        pit mining and $54/tonne for underground mining.
    (2) Mineral resources which are not mineral reserves do not have
        demonstrated economic viability. The estimate of mineral resources
        may be materially affected by environmental, permitting, legal,
        title, socio-political, marketing, or other relevant issues.
    (3) The quantity and grade of reported inferred resources in this
        estimation are uncertain in nature and there has been insufficient
        exploration to define these inferred resources as an indicated or
        measured mineral resource and it is uncertain if further exploration
        will result in upgrading them to an indicated or measured mineral
        resource category.
    (4) The mineral resources in this press release were estimated using the
        Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM
        Standards on Mineral Resources and Reserves, Definitions and
        Guidelines prepared by the CIM Standing Committee on Reserve
        Definitions and adopted by CIM Council December 11, 2005.

    Commenting on the results, Mr. Kim Tyler, President, stated, "This
resource estimate is an important milestone for the project. Having the
majority of the Kenbridge resource in the measured & indicated classes
provides greater confidence in the mineralization and the potential for
expansion. The definition drilling from surface to the 375 m elevation had a
positive impact on the upper portion of the underground resources. We expect
similar results as we continue infill drilling at depth. This will be
accomplished with an advanced exploration program currently in the permitting
    Compared to the previous NI 43-101 resource estimate (Jan '08), total
contained nickel in measured and indicated classifications has increased from
52.2M lbs to 97.7M lbs, a gain of 87%.
    The Kenbridge deposit occurs in a vertically dipping, lenticular gabbro
and gabbro breccia with surface dimensions of approximately 250 m x 60 m. A
total of 532 holes including 62,487 m of drilling define the Kenbridge
database. Inverse distance squared grade interpolation was utilized to
determine block model grades using parameters set by variographic analyses.
The Kenbridge mineral resource model was constructed in Gemcom using a
geostatistical block model approach constrained by net smelter return, (NSR),
wireframes considering both nickel and copper composite grades. Intrusive
dykes and country rock xenoliths were modeled. Block size was set at 5 m x 5 m
x 5 m. Assays were composited to 1.5 m lengths with assay detection limit
values assigned to unsampled intervals. An image of the block model can be
viewed on the Company's website at
    Kenbridge was explored by Falconbridge Limited between 1952 and 1958
where a 2,042 ft (622 m) shaft, two working levels and a bulk sample / pilot
plant were completed.
