NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES

Groundstar Resource Limited ("Groundstar" or the "Company") (TSX VENTURE:GSA) provides the following update regarding its operations in Egypt. Groundstar has been informed by the operator of the West Kom Ombo block, Energean Oil & Gas, that the WKO-3X well that was spud on March 7, 2011, reached basement at 2,523 feet.

The main objective of the well was to provide a second stratigraphic control point, approximately 100 km southwest of the WKO-1X well location, in an area with very sparse geological and geophysical data coverage. The results of the WKO-3X well will be used for defining and further optimizing the future exploration approach in the license area. A regional aeromagnetic survey is currently under review to better define the optimum location of future exploration wells in this vast unexplored block (31,520 km²).

The WKO-3X well was the second of two committed frontier exploration wells in the vast and highly unexplored West Kom Ombo License that fulfills the contractual obligation of first extension of the exploration phase.
