Portrush Announces Drilling Permit

VANCOUVER, BC -- (MARKET WIRE) -- March 29, 2007 -- Portrush Petroleum Corporation (TSX-V: PSH) (OTCBB: PRRPF) (http://www.portrushpetroleum.com) has been advised that a drilling permit has been granted for the Portrush et al No.1 - Moore 5 - 13- lll in Moore township, Lambton County, Southwestern Ontario. The prospect is located in the heart of a gas storage area on trend and mid point between two pinnacle reef gas storage pools, Kimball Colinville and Waubuno.

The Waubuno pool produced 6.01 BCF before being converted to gas storage and this prospect is postulated to have a similar reservoir with slightly less volume of gas in place.

Due to leasing problems the drilling has been delayed for many years. The leasing problem was resolved through "Force Pooling" in February 2007. It is anticipated the prospect will be drilled to a depth of 3,300 feet later this year. Portrush intends to retain more than a 50% interest in the project.

The operator at Mission River, Texas has advised that a proposal to drill additional deep tests is currently being evaluated and intends to resume drilling once the evaluation is completed.
