Encouraging Results At Cerro Solo Uranium Project

Portal Resources Ltd. (TSX Venture Exchange -- Symbol: PDO) is pleased to announce encouraging results from the initial uranium exploration the Company has carried out on three exploration concessions within the San Jorge Basin in Chubut province Argentina. Portal has the right to earn a 60% interest in the concessions under terms of an option agreement with Consolidated Pacific Bay Minerals Ltd.

Mapping and interpretation of satellite imagery defined areas within the concessions that are believed to be underlain by the Los Adobes Formation which, approximately 30 kilometers to the east, hosts the Cerro Solo deposit owned by Compania Nacional de Energia Atomica (CNEA). Cerro Solo is the largest uranium deposit in the San Jorge Basin with an 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.

Alpha Track surveys were completed in areas of alluvial cover to define zones with anomalous radioactivity reflecting uranium mineralization in the sedimentary sequence at depth. Six of sixty Alpha Track samples collected on 200 meter intervals on 2 lines 4 kilometers apart produced anomalous track etch results. Based on these encouraging results, additional sample lines are being completed with results to be released as they become available.

Additionally, Portal has renegotiated terms of the Cerro Solo option agreement with Consolidated Pacific Bay Minerals Ltd. under which Portal is earning its interest in the project. As significant delays have been encountered in obtaining final approval and registration of the three exploration concessions comprising the project, terms of the agreement have been amended so that both timing of payments (with the exception of the initial payment which was made on signing) as well as work commitments are now tied to the date on which final approval and registration of the concessions are received from the Chubut government.

All work on the Cerro Solo joint venture is carried out by competent geological staff in Argentina under the overall guidance of Portal's VP Exploration, Mr. Alex Boronowski, P.Geo. British Columbia, the designated Qualified Person in accordance with National Instrument 43-101. Mr. Alex Boronowski has reviewed this news release.

* The above resource estimates are historical and do not conform to the standards of National Instrument 43-101. They may vary materially from estimates made in accordance with the classification made pursuant to NI 43-101 and should not be relied upon. The company's qualified person (QP) has not done sufficient work to classify the historical estimate as a current mineral resource and is not treating the historical estimates as current mineral resources as defined in NI 43-101. However, the company's QP believes the historic estimate is relevant and offers a fair description of the project's known mineralization.
