Portrush Announces Scanio-Hawn No. 1 Well

VANCOUVER, BC -- (MARKET WIRE) -- January 22, 2007 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) (http://www.portrushpetroleum.com) announced today that the operator of the Mission River, Texas property has commenced drilling the next deep test utilizing a Patterson-UTI drilling rig capable of drilling to 8,500 feet with a 4" pipe. The well spudded earlier today.

The well has been re-named the Scanio-Hawn No.1.

The operator recently completed a 3-D seismic shoot on the property and has used the data to enhance the Scanio-Hawn location.

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. 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 has been completed. This will allow an increase in the production capacity.
