Portrush to Drill a Second Deep Test at Mission River

VANCOUVER, BC -- (MARKET WIRE) -- April 11, 2006 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTC BB: PRRPF) ( wishes to announce that the operator has proposed drilling another deep test on the Mission River lease 1,000 feet north of the Scanio Shelton #6.

The recoverable proved producing reserves from the Scanio Shelton #6 are estimated at 5 BCF and 200,000 barrels of condensate. The newly proposed well will be drilled to further evaluate the aerial extent of the producing zone. The well will also help to fully develop the other sands encountered in the Scanio Shelton #6. It has been agreed in order to effectively drain the reservoir and recover the reserves another well is needed.

The newly proposed well will be drilled to properly develop the sands encountered in the Scanio Shelton #6 and is a very significant departure from the original twelve well shallow drilling program. It is considered in the best interest of all participants because the potential new reserves to be captured far exceed the potential reserves in the shallower formations.

An announcement on the timing of the drilling and a decision on further drilling will be taken in due course.

The Scanio Shelton #6 has been placed on production at a rate of two and a half million cubic feet of gas and one hundred and fourteen barrels of condensate a day.

The Mission River lease is being developed 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 8,800 feet. Portrush has a 10% working interest in the field. To date seven wells have been drilled and all seven wells have been placed on production.

The Company will extend the term of previously granted stock options to Directors and Officers which expire this month by granting options to directors to purchase up to 1,600,000 shares at $0.15 per share for a period of 3 years.
