Northern Sun Makes Canadian Gas Discovery

Northern Sun Exploration has made a new gas pool discovery at the Company's property near Lavoy, Alberta. The Company's 100% working interest exploration test well was drilled to a depth of 650 meters encountering gas in six separate and distinct zones. The well was successfully completed and flow-tested for a seven day period, and results indicate that the well should initially produce at a combined rate of 2 million cubic feet per day (333 barrels of oil equivalent per day). A pipeline tie-in to a third party facility is currently being surveyed and regulatory approvals should be in place for gas sales by the end of June 2005.

The Company has surveyed and licensed a follow-up well to be drilled immediately into the new discovery pool based on data obtained from the initial well.

Chris Cooper, President & CEO, commented "The successful Lavoy well will add significant production to the Company immediately and we are optimistic that a successful follow-up well coupled with our existing production will help the Company achieve management's goal to exit 2005 at over 1000 boepd."

The Company also reports that, due to wet conditions, completion and testing activities on the three exploration wells at Grouard are still underway, with results expected within the next two weeks.
