Vancouver, British Columbia CANADA, December 03, 2008 /FSC/ - Portrush Petroleum Corporation (PSH - TSX Venture, PRRPF - OTCBB), wishes to announce that the #14 well in the Mission River Texas Field has been drilled and completed. The well was drilled to a depth of 7,795' and was selected to penetrate certain specific objectives between 7,200' and 7,700' that were found productive in the No. 11 and No. 12 wells. The target zones were intersected and the operator intends to have the well on production within two weeks.

Two additional wells are planned to be drilled in the coming weeks.

The last 4 wells drilled were all successful and new pay zones were found that have not been previously produced in the Field. Each new well is located to develop the newly discovered Lower Frio formations but will also be positioned to develop the proven Upper Vicksburg (8,000' to 8,500').

Drilling at the Portrush et al #2, Moore 6-12-III well on its Waubuno property in Moore (St. Clair) Township, Lambton County, Southwestern Ontario is continuing and is anticipated to reach total depth within the next week. Portrush holds a 65% working interest in the project.
