	NEWS RELEASE 08-07 Thursday, May 08, 2008

Portal Expands Tiger Uranium Project Portal Resources Ltd. (TSX-V: PDO) announces that the San Rafael project in Mendoza province consisting of claims held under the Minera Rio de la Plata S.A. (MRDP) and San Pedro agreements, has been reorganised. Portal expanded the Tiger uranium project from 5 claims (26,069 hectares or 101 square miles) to 9 claims totaling 44,924 hectares (174 square miles) which will continue to be held under the Minera Rio de la Plata (MRDP) exploration agreement. Additionally, the payment due on April 9, 2008 under the MRDP agreement has been rescheduled with a new due date of July 10th 2008. The Tiger project partially surrounds the Sierra Pintada mine, belonging to Compania Nacional de Energia Atomica (CNEA), an Argentinean government corporation, as well as hosts excellent exploration targets in the favourable host stratigraphy extending 40 kilometers to the south of the Sierra Pintada mine. Sierra Pintada produced 5 million lbs of U3O8 from 1974 through 1986 and has a remaining historical resource* of 20 million lbs U3O8 at an ore grade of 0.12% (CNEA Report January 2006). Also, as part of the reorganization of the San Rafael project, Portal has terminated the San Pedro agreement and returned 53 claims totaling 144,856 hectares held under the MRDP agreement. These claims included the Anchoris copper-gold porphyry target as well as potential for low sulphidation gold-silver mineralization. "Portal believes that the Tiger project has good potential to host a significant Sierra Pintada style uranium deposit" states Bruce Winfield President and CEO of Portal Resources, "and we look forward to pursing this potential." Portal Resources Ltd. was founded in 2004 and is a precious and base metal exploration company focused on gold/silver, molybdenum, and uranium assets in Argentina and North America. The Company currently controls approximately 203,000 hectares (784 square miles) of mineral rights in three primary project areas in Argentina and southwestern Colorado, USA.
