Portrush Announces Well Reaches 8,650 Feet

VANCOUVER, BC -- (MARKET WIRE) -- February 10, 2006 -- Portrush Petroleum Corporation (TSX-V: PSH), (OTC BB: PRRPF) ( today provided an update regarding its continuing operations on the Scanio-Shelton #6 well in the Mission River property in Texas.

The well has been drilled to a depth of 8,650 feet since the Company's last report. A 7.62-inch liner had been set at a depth of 8,170 feet and drilling resumed earlier this week. As drilling progressed indications of increasing pressure resulted in a decision to run an additional five-inch liner in the interval between 8,170 and 8,650. This casing string has now been cemented in place and preparations are underway to drill ahead to a planned total depth of around 10,500 feet. Mud weight has been increased to 15.0 pounds.

An intermediate logging program was completed over the Frio and Vicksburg formations in the interval between 8,170 and 8,650. Initial interpretation of the logs has indicated the presence of several hydrocarbon-bearing sandstones in this section.

The interval logged in this run and the previous logging run has examined the Frio and Vicksburg formations to a depth of 8,650 feet. There is potential for other sands to be present in the remaining 1,900 feet of section still to be examined as drilling continues to the planned total depth of 10,500 feet. The drilling contractor has allocated thirty days in total to drill the well.

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.
