Portal recently signed an agreement to earn a 60% interest in the Cerro Solo Basin Project of Consolidated Pacific Bay Minerals Ltd. The project located within the San Jorge Gulf basin in central Chubut province in southern Argentina consists of three adjoining concessions totaling 30,000 hectares or 115 square miles.

The Cerro Solo Basin Project is located approximately 32 kilometers to the east of the Cerro Solo Uranium Deposit owned by CNEA. Cerro Solo 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%.

Portal's uranium exploration efforts in Chubut Province consist of 12 separate claims covering 320 square miles called "the La Pampa Uranium Project". Within the project area several strong airborne uranium radiometric anomalies and exposures of sandstones and conglomerate units are present along a north south trending portion of the Los Adobes Formation 45 kilometers long by 15 kilometers wide.

Mendoza Province The Tiger project consists of 5 claims covering 100 sq miles surrounding the Sierra Pintada Mine (CNEA) that produced 5 million lbs of uranium from 1974-1994 with remaining resources of 20 million lbs at an ore grade is 0.12% uranium. Portal has outlined 6 target areas over a strike length of 20 kilometers. Highest priority target lies near the southern boundary of the Sierra Pintada claims.

Phase I exploration

Phase I exploration, budgeted at US$400,000 has begun on the Tiger and La Pampa uranium projects. Exploration consists of mapping, sampling, surface radiometric spectrometer surveys and initiating permitting for up to 150 wide spaced drill holes. Phase II exploration will consist of approximately 20,000 - 25,000 meters of percussion or reverse circulation drilling to test the most favorable target areas.

Portal's portfolio now contains 400 square miles of prime exploration land in close proximity to, or surrounding, large uranium deposits. These high-potential projects are also amenable to year round exploration, providing for a consistent news flow, and the management team is a cohesive experienced group that has had great success in the past and is looking to duplicate that success with these projects.

* 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 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.
