TORONTO, ONTARIO--(Marketwire - April 7, 2009) - Polar Star Mining Corporation ("Polar Star" or the "Company") (TSX VENTURE: PSR.V) announced today that it has received a draft of SRK's Independent Technical Report on the Chepica Project located near the town of Talca in Region VII, southern Chile.

Highlights of the Report are as follows:

- Total Measured and Indicated Resources of the Chepica Number 1 Vein system are 401,000 tonnes grading 2.6 grams/tonne gold, 8.3 grams/tonne silver and 0.48% copper using a cut-off grade of 0.6 grams/tonne gold, uncut.

- The current Chepica plant has been designed to process up to 120 tonnes/day.

A separate metallurgical report was received from the University of La Serena Metallurgical Laboratory stating that their test work on drill core indicates the copper and gold recoveries are in the order of 65%. These metallurgical results have not yet been included in SRK's technical report.

The Chepica process plant is currently milling limited amounts of exploration and development rock from the Number 2 Vein.

The final SRK report will be posted on SEDAR subsequent to review and approval.

Estimation was based on 50 of 66 drill holes corresponding to 5,299 meters of diamond core drilling, together with 19 underground channel samples and 2 trench samples totalling 92.5 meters in length.

The resources were estimated by Ordinary Kriging using block model sizes of 10 by 10 by 10 meters.
