Portrush Announces Scanio-Shelton #7

VANCOUVER, BC -- (MARKET WIRE) -- May 9, 2006 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTC BB: PRRPF) ( wishes to announce that the next deep test on the Mission River lease will be drilled in early June. The well, the Scanio/Shelton #7, will be drilled approximately 1,200 feet north of the Scanio Shelton #6 and the operator has hired the drilling contractor who successfully drilled the number six well.

The Scanio Shelton #6 was drilled earlier this year and was 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. Work is already underway to prepare the lease for the number seven well.

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 and through the 8,400 pay section 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.

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.
