Portal Completes Drilling on Slick Rock Uranium Project

Portal Resources Ltd. (TSX VENTURE:PDO) announces that it has completed a rotary drilling program of 12,860 feet, (3,920 meters) in 18 vertical drill holes on its Slick Rock Uranium Project located within the Uravan Uranium-Vanadium Mineral Belt, in southwestern Colorado. The ore bodies in the Slick Rock District are hosted within relatively coarse grained, cross-bedded, sandstone units of the Salt Wash Member of the Morrison Formation representing river channel fill deposits.

Down-hole gamma logging/probing of Portal's holes was conducted by an independent consulting service to define radioactive horizons hosting uranium mineralization. Two of the 18 holes returned equivalent grade percentages U3O8 (e%U3O8) above e0.02% U3O8 (0.44 lbsU3O8/tonne). Drill hole C-4 intersected 0.61 m (2 feet) averaging e0.55% U3O8 (12 lbs/tonne) between 579.5 feet (209.3m) and 581.5 feet (209.8m) in depth. According to the induction (conductivity) logs, the mineralization appears to be related to a narrow sandstone horizon within a shaly-sandstone unit believed to belong to the Jurassic age Salt Wash Member of the Morrison Formation. C-13 intersected 2.5 ft (0.76m) averaging e0.022% U3O8 between 591.5 feet (213.6 m) and 594.0 feet (214.5 m) in depth. The hole is located approximately 380 meters southwest of C-4. These intersections are interpreted as roll-front style mineralization in sandstone units formed in meandering fluvial channels.

An additional 8 of the 18 drill holes returned anomalous e%U3O8 values ranging from e less than 0.01% to e less than 0.02%U3O8. Three of these holes represent 100 meter step-outs to the south-southwest, east and west from C-4 The distribution of 4 of the holes containing anomalous e%U3O8 values plus C-4 suggest that there is a zone of interest trending east-west which measures approximately 30 meter wide by 400 meter long.

All work on Slick Rock Uranium Project was carried out by Mr. Don White, P.Geo 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.
