Portal Finds Encouraging Clues In Initial Uranium Exploration On
La Pampa Uranium Project

Portal Resources Ltd. (TSX-V: PDO) is pleased to report on progress of Phase I exploration on the La Pampa uranium concessions in the Province of Chubut, Argentina.

Portal's La Pampa uranium project consists of nine exploration concessions covering 53,969 hectares or 208 square miles located 40 to 80 kilometers southwest of the Cerro Solo uranium deposit of CNEA. The Cerro Solo deposit has a historical resource* of 10 million pounds of U3O8 at a grade of 0.30% and 3.3 million pounds of molybdenum at a grade of 0.20% molybdenum. Cerro Solo and other uranium deposits and occurrences in the area are hosted within the Los Adobes Formation consisting of coarse-grained sandstones and conglomerate units representing ancient river channels.

Initial prospecting within one of Portal's nine concessions has identified an area believed to be underlain by the Los Adobes and Cerro Barcino Formations. Mapping of this target area shows a thicker section of coarse sandstone and pebble conglomerate which is typical of the more favorable parts of the Los Adobes Formation to host uranium mineralization. Additionally prospecting with a spectrometer has identified anomalous or above background radiometric values in the same zone.

Portal is encouraged by the initial success of its prospecting program on this area. Next week a detailed ground radiometric survey will commence to determine the size of the area of interest and conduct detailed mapping to determine the thickness and stratigraphic position of the sandstone and pebble conglomerate within the sedimentary sequence.

The La Pampa uranium project covers strong airborne uranium radiometric anomalies along a north-south trending portion of the Los Adobes Formation sandstones 45 kilometers long by 15 kilometers wide. The Phase I initial prospecting efforts will also continue within the other eight La Pampa concession areas.

All work on the project is carried out by competent geological staff in Argentina under the overall guidance of Mr. Gary Nordin, P.Geo. British Columbia, the designated Qualified Person for the La Pampa project in accordance with National Instrument 43-101.
