Portrush Update on Production

VANCOUVER, BC -- (MARKET WIRE) -- March 7, 2007 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) (www.portrushpetroleum.com) is pleased to provide an update regarding its continuing operations on the Scanio-Hawn No.1 well on the Mission River property in Texas.

The well, drilled to a depth of approximately 8,600 feet earlier last month, encountered hydrocarbon bearing sandstones within the main target zone. One of these zones was perforated and the well was placed on production and connected to the sales line this week.

The well has been placed on production at a rate of approximately two hundred and fifty thousand cubic feet of gas per day. Production is through a 10/64" choke and Flowing Tubing Pressure is 1,900 pounds.

All production testing was conducted into the sales line. Existing production equipment has been upgraded to deal with the larger production volumes. Total daily production from the field is approximately 2.5 million cubic feet of gas and approximately 90 barrels of condensate a day.

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, nine wells have been drilled and all have been placed on production.
