Gastar Announces Update on Australian Activity

Gastar Exploration Ltd. (AMEX:GST) (TSX:YGA) together with joint venture partner Eastern Star Gas (ASX: ESG) announced today the results from the latest exploratory corehole drilled on license PEL 238 located in New South Wales, Australia.

The Edgeroi-1 corehole was drilled approximately 26 miles north of the existing Bibbliwindi and Dewhurst areas and intersected a total of more than 70 feet of coal, including 33 feet of coal within the primary targeted Bohena coal seam. The coals intersected in the Edgeroi-1 well appear to be fractured with high gas contents. These results are consistent with the results seen in the Bibbliwindi and Dewhurst areas where over 50 feet of fractured, gas-rich coal was found in the primary Bohena coal seam.

"The results from the Edgeroi-1 corehole support the pre-drill estimates for a significant amount of recoverable coalbed methane from the Edgeroi prospect area, extending the CBM potential on PEL 238 much further north than previously mapped," said J. Russell Porter, Gastar's President and Chief Executive Officer.

"Along with the earlier results seen to the south, we believe this corehole is additional validation of the tremendous resource potential of PEL 238. With the flurry of recent acquisitions of independent CBM players in eastern Australia, we believe that PEL 238 is now the largest independently owned CBM resource in eastern Australia and will be attractive as a source of gas for both domestic and export purposes."

The SEC has generally permitted oil and gas companies, in their filings with the SEC, to disclose only proved reserves that, under SEC definitions and guidelines, a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. This press release discloses "probable" reserves that the SEC's guidelines would prohibit us from including in our filings with the SEC.
