Portrush Releases Waubuno Seismic Results

VANCOUVER, Aug 06, 2008 (BUSINESS WIRE) -- Portrush Petroleum Corporation (PSH)(US:PRRPF) (http://www.portrushpetroleum.com) completed a 3D Seismic Survey in early May 2008 over its Waubuno property in Moore (St. Clair) Township, Lambton County, Southwestern Ontario and has received a favorable geophysical report and interpretation from its consultants in Calgary.

A good Niagaran pinnacle reef anomaly is reported to lie within the 150-acre unit known as the Waubuno Prospect, which was spaced and pooled by Portrush in 2005 and 2006. In 2007 the Portrush et al #1, Moore 5-13-III exploratory test was drilled and suspended after encountering near reef geological conditions. This Well was drilled on limited 2D Seismic data and the original interpreted anomaly is now considered as "side swipe" to a pinnacle reef.

Several key maps and Seismic lines from the 3D survey are presented in the Report to show an interpreted Niagaran Pinnacle Reef exists within this 3D volume. The A2 Carbonate time structure map shows an A2 structural high on the eastern flank of a B Salt hole. This is the area thought to be most influenced by the interpreted pinnacle reef, which underlies this time high. This is further supported by an A2 Salt map which shows salt termination against the interpreted reef margin. An A1 Carbonate amplitude map reveals a strong amplitude anomaly along the western margin of the interpreted pinnacle reef. The A1 Carbonate Sucrosic Dolomite porosity with an oil show encountered in the Portrush et al #1, Moore 5-13-III suspended well was tied to the Seismic. This porosity and aerial distribution of Dolomite is a strong indication of reefing to the east. It also represents an added bonus of a potential commercial oil leg existing in Lot 13, adjacent to the west flank of a pinnacle reef in Lots 12 and 13, Concession III, Moore Township.

A drill location to test the interpreted crestal position of a postulated pinnacle reef has been surveyed. An application for a drill permit for the Portrush et al #2, Moore 6-12-III was filed by Hadley Resources Limited (Canada) with the Ministry of Natural Resources on July 31, 2008
