Portrush Announces Well Reaches 8,104 Feet

VANCOUVER, BC -- (MARKET WIRE) -- February 2, 2007 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) ( 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 depth of 8,104 feet. As drilling progressed and indications of increasing pressure became evident, drilling was suspended and the well was logged. A 7-inch liner will be cemented in place. Drilling can then continue in the over pressured zone to the planned total depth of around 8,600 feet.

An intermediate logging program has been completed over the Frio and Vicksburg formations above 8,000 feet. This included reservoir pressure measurements and reservoir fluid sampling. Initial interpretation of the data indicates the presence of hydrocarbon bearing sandstones above this level.

There is potential for other sands to be present in the remaining 600 feet or so of section still to be examined as drilling continues to the planned total depth of 8,600 feet.

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

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.
