Portrush Announces #12 Well Producing at 2 Million Cubic Feet Per Day

VANCOUVER, Sep 15, 2008 (BUSINESS WIRE) -- Portrush Petroleum Corporation (PSH)(US:PRRPF) (http://www.portrushpetroleum.com) wishes to announce that the #12 well has been placed on production at a rate in excess of 2 million cubic feet per day. All wells in the Mission River property in Texas have been placed on production and the field is producing at a rate of approximately 3.8 million cubic feet of gas and 127 barrels of oil a day. The operator receives an 11.44% premium on gas sales due to the high BTU value of the gas. Four additional wells are planned for the lease.

Portrush's monthly revenue from the field at this rate of production and based on its 10% working interest is approximately $100,000 per month. A reserve report is being completed and the operator anticipates drilling the first of the four wells in early November. Three of the wells will be drilled to 8,700 feet and one will be drilled to 6,500.

The gathering system will require upgrading to handle any anticipated increase in production volumes arising from these additional wells.
