Petrostar Petroleum Corporation: GEN-2 Down Hole Tool Field Testing Commences on Maidstone Property, Plans for $350,000 Flow-Through Financing

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 11, 2007) - Petrostar Petroleum Corporation (TSX VENTURE:PEP)(FRANKFURT:LMQ); "Petrostar" or the "Company") is pleased to announce that the first phase of field-testing of its second generation Down Hole Tool (GEN-2 DHT) commenced at its Maidstone testing facilities on December 7, 2007.

The GEN-2 DHT, which evolved from applying modifications to the successfully tested first generation DHT, has the capability of reaching temperatures of 250ºC, a significant increase from 190ºC that was achieved by the first generation DHT, and has been redesigned to maintain the targeted temperature for a longer timeframe in the well bore allowing for increased down-hole steam and pressure generation. As well, the GEN-2 DHT is capable of reaching temperatures of 250ºC utilizing a 22-kilowatt generator as opposed to a 66-kilowatt generator required by the first generation DHT.

During this phase of field-testing, the GEN-2 DHT reached the temperature target of 250ºC within three hours of deployment. Furthermore, the temperature of the water in the well bore reached 93ºC. The next step in the first phase of the field diagnostic testing is to pull the GEN-2 DHT out of the well bore to evaluate the integrity of the new stainless steel wrapped electrical cable, the capabilities of the newly designed and constructed hydraulic delivery system and the GEN-2 DHT itself, which has commenced. The second phase of field-testing will commence immediately after these evaluations are complete.

The Company plans to issue, through a non-brokered private placement, up to 1,750,000 units (the "Units") of the Company at a price of $0.20 per Unit for a total of $ 350,000. Each Unit will consist of one common flow through share (a "Flow Through Share") in the capital of the Company and one non-transferable share purchase warrant. Each full warrant will entitle the holder thereof to purchase one additional common share of the Company for a period of two years following the closing date at a price of $0.25 per share in the first year and $0.30 per share in the second year. The private placement is subject to the acceptance of the TSX Venture Exchange and all shares issued there under will be subject to a 4-month hold period.

Mr. Sandy Sprinkle, P.Eng and Consultant to Petrostar, a qualified person under NI51-101, has approved the technical content of this news release.

On behalf of the Board of Directors,
