Portrush Announces Scanio-Shelton No. 8

VANCOUVER, BC -- (MARKET WIRE) -- December 5, 2006 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) (http://www.portrushpetroleum.com) announced today that the operator of the Mission River, Texas property has finalized the location for the next deep test and anticipates drilling the well in early January utilizing a Patterson-UTI drilling rig capable of drilling to 8,500 feet with a 4" pipe.

The operator recently completed a 3-D seismic shoot on the property and has used the data to enhance the Scanio-Shelton No. 8 location. Wellsite preparations will commence immediately.

The Company holds a 10% interest in the Mission River property and the seismic shoot covered the entire property of just over 700 acres. It is anticipated the seismic data will support a multi-well deep drilling program on the property after the completion of this well. The seismic information will be used to locate the wells and determine the optimum number of wells that will be required to drain the reservoir. To date two deep wells have been drilled and successfully placed on production. An upgrade of the pipeline gathering system is underway. This will allow an increase in the production capacity.

In respect to the Lenox property in Michigan, the Company has received a report recommending drilling of a third well on this property. The Company is reviewing this proposal in addition to another proposal to develop a similar pinnacle reef project located in the province of Ontario.

The TSX Venture Exchange has not reviewed this press release and has neither approved nor disapproved the information contained in this press release.

The statements made in this Press Release may contain forward-looking statements that may involve a number of risks and uncertainties. Actual events or results could differ materially from the Company's expectations and projections.
