Polar Star Files NI 43-101 Report on Chépica Copper/Gold Project in Chile


    TORONTO, June 18, 2009 /CNW/ - Polar Star Mining Corporation (TSX-V: PSR)
("Polar Star" or the "Company") is pleased to report it has completed the
Technical Report on its Chépica copper/gold project in Chile.
    As announced on May 21, 2009, the Company together with SRK Consulting of
Santiago Chile have refined the geostatistical parameters of the resource
model presented in the draft received in April. The main difference being the
change from one generalized search ellipsoid in the April draft to two
sub-ellipsoids orientated parallel to the strike of both sections of the
Chépica Number 1 Vein system. The Company has now filed the NI 43-101
compliant Technical Report on SEDAR.

    Highlights of the report

    -   Total Measured and Indicated Resources of the Chépica Number 1 Vein
        system are 178,000 tonnes grading 4.1 grams/tonne gold,
        9.5 grams/tonne silver and 0.51% copper using an un-capped cut-off
        grade of 1.3 grams/tonne gold.

    -   The current Chépica plant should allow for processing at the designed
        capacity of 120 tons/day of sulphide ore. Operating costs of US$8/ton
        are in keeping with the design and size of the plant.

    -   SRK Consulting is of the opinion that there are excellent exploration
        opportunities at Chépica to expand the current size of the copper-
        gold project.

    (*) reported at a cut-off of 1.30 g/t gold, not capped

    A resource cut-off of 1.3 grams per tonne of gold was applied to the
resource based on experience with the mill on site at Chépica and other
operations in the region, and the Company considers that 1.3 grams per tonne
is an appropriate indication of commercial viability.
    Estimation was based on 50 of 66 drill holes corresponding to 5,299
metres of diamond core drilling, together with 17 underground channel samples
and two trench samples totalling 92.5 metres in length.
    The resources were estimated by Ordinary Kriging using block model sizes
of 2.5 by 2.5 by 5 metres.
