Warrants

/NOT FOR DISTRIBUTION TO UNITED STATES WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES /

TORONTO , Nov. 9, 2009 /CNW/ - Polar Star Mining Corporation (TSXV: PSR) ("Polar Star" or the "Company") announces an update for the Third Quarter activities on its 100% owned Montezuma Property in Chile . The Company also announces the early exercise of over 2.78 million warrants of the company providing proceeds of $1.25 million .

    
    Montezuma

    -   Montezuma consists of the 100% owned exploration concessions staked
        by Polar Star totalling approximately 50,000 hectares and covering
        25 kilometres of the West Fault, well known for the exceptional size
        of its associated porphyry copper deposits such as Escondida and
        Chuquicamata.

    -   During August 2009, select holes from the March 2009 drill campaign
        were re-analysed for gold, silver and a variety of other associated
        elements. Assays received contain gold values in the range of 0.2 -
        1.8 g/t and silver values in the range of 2 - 49 g/t. Recent detailed
        mapping of an old hand trench, 200-300m north of hole 7 has uncovered
        a 70m wide zone of copper oxides including chrysocola, atacamite,
        cuprite and possibly chalcocite within 20cm of surface. This showing
        lies on the south edge of a 1.5 sq km area of alteration and staining
        visible on the enhanced satellite image. Recently received
        preliminary assays show a 20 metre zone of Cu, Au and Ag enrichment,
        grading from a low of 0.22% to a high of 31.3% Cu, from a low of
        0.08 g/t to a high of 11.75 g/t Au and from a low of 0.5 g/t to a
        high of 618 g/t Ag.

    -   During September and October 2009, an additional 74.7 line kilometres
        of IP surveys, digital enhancement and re-interpretation of the
        project satellite imagery were completed and geological mapping and
        soil sampling of the IP electrode pits was initiated. Data received
        indicates a new anomaly, 3 kilometres north of the main anomaly, at
        least 600 metres wide and 3 kilometres long open to the north, south
        and west.

    -   Polar Star continues its drill target selection process and plans to
        begin drilling in late November 2009. Attached is an updated map of
        the Montezuma anomalies.

    Region II

    -   In July 2009, Polar Star staked an additional 8 properties in the
        Mega Porphyry Belt to the south of the Company's Montezuma Property
        and to the north of the Zaldivar and Escondida mines. The properties
        total 63,700 hectares and are located within the Domeyko Fault System
        and in some cases along the West Fault.

    Early Exercise of Warrants

    -   As of the date of this release, 2,779,366 warrants, expiring in
        August 2010, were exercised early, providing proceeds of $1,250,715
        to the Company. HudBay Minerals Inc. announced November 3, 2009 that
        they acquired 1,004,336 common shares of Polar Star through the early
        exercise of the August 2010 warrants, bringing its aggregate holding
        of common shares to 6,873,704. An international institutional
        investor also exercised their warrants early.
    

"We are encouraged by the progress we are making in advancing our properties," stated Doug Willock , President and CEO of Polar Star. "The early exercise of warrants is an endorsement of our work and provides funds that will be used for further exploration."
