TORONTO, Nov. 9, 2009 /CNW/ - Polar Star Mining Corporation (TSXV: PSR.V) ("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."
