Portrush Announces Well Reaches Total Depth

VANCOUVER, BC -- (MARKET WIRE) -- February 8, 2007 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) (http://www.portrushpetroleum.com) is pleased to provide an update regarding its continuing operations on the Scanio-Hawn No.1 well in the Mission River property in Texas.

The well has been drilled to a total depth of 8,670 feet and a decision to complete the well has been taken.

Drilling was suspended and an intermediate logging program was completed over the Frio and Vicksburg formations before a 7 inch intermediate casing was set at approximately 8,000 feet. The well was then drilled to a depth of 8,670 feet and the remaining portion of the well was logged. Initial interpretation of the data indicates the presence of hydrocarbon bearing sandstones in several zones to a depth of 8,636 feet.

A final interpretation of the overall hydrocarbon column encountered, and hence estimated reservoir volumes will be made following completion of the well and full analysis of all the log data and fluid sampling recovered.

The Mission River lease is operated by McAlester and is located at the south end of the town of Refugio, Refugio County, Texas. The field has multiple pays at depths ranging from 2,000 to 8,500 feet. Portrush has a 10% working interest in the field. To date eight wells have been drilled and all have been placed on production.
