Portrush Announces Well Reaches 7,622 Feet

VANCOUVER, BC -- (MARKET WIRE) -- January 27, 2006 -- Portrush Petroleum Corporation (TSX-V: PSH), (OTC BB: PRRPF) (http://www.portrushpetroleum.com) is pleased to provide an update regarding its continuing operations on the Scanio/Sheldon No.6 well in the Mission River property in Texas.

The well has been drilled to a depth of 7,622 feet since the Company's last report. As drilling progresses and indications of increasing pressure become evident a 7.62-inch liner will be cemented in place. It is anticipated this will happen at approximately 8,000 feet in the next few days. Drilling will then continue in the over pressured zone to the planned total depth of around 10,500 feet. Mud weight at present is 9.5 pounds. This will increase substantially after the intermediate string is set.

An intermediate logging program will be completed over the Frio and Vicksburg formations above 8,000 feet. Initial interpretation of the data will be made to determine the presence of hydrocarbon bearing sandstones above this level.

The intermediate interval logged and described above will examine the Frio and Vicksburg above a depth of 8,000 feet. There is potential for other sands to be present in the remaining 2,500 feet or so of section still to be examined as drilling continues to the planned total depth of 10,500 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 six wells have been drilled to approximately 6,500 feet and all six have been placed on production.
