Update on Land Acquisition and Permitting on Portal's Slick Rock Uranium Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 17, 2008) - Portal Resources Ltd. (TSX VENTURE:PDO) is pleased to provide a progress report on the Company's Slick Rock uranium project located in the southern portion of the prolific Uravan Mineral District in Colorado which has historically produced over 84 million pounds of uranium oxide (U3O8) and 220 million pounds of vanadium oxide (V2O5).

The company has added to its property position through the acquisition by staking of six Bureau of Land Management claims totaling approximately 100 acres. These claims, which are contiguous with Portal's existing properties, cover at least one area of closely spaced holes drilled in the 1970's on a zone of uranium mineralization located approximately two miles to the northeast on what is believed to be the mineralized trend that hosts the past producing Wilson and Silver Bell mines.

As previously announced, Portal plans to carry out a 3500 meter drill program in early spring of 2008. The planned program will consist of 15 holes to a depth of 200 meters. Compilation of previous work carried out in the 1970's and 1980's on the properties, has identified several areas of previous drilling with hole spacing of 50 to 150 meters which, historically in the district, indicates drilling on uranium mineralized zones. Portal plans to further define these mineralized areas through drilling both within them and on projected extensions.

Permitting for the planned drill program is proceeding well with applications having been submitted in late 2007. The permits anticipated to be issued in March will allow for the drill program to commence in the spring of 2008.

"The Slick Rock project is an exciting opportunity to explore for new orebodies in this prolific district and we are very excited with the upcoming drill program which will be the first drilling in over 20 years on these historic mineralized trends," states Bruce Winfield, President of Portal.

Mr. Alex Boronowski, P.Geo, British Columbia is the designated Qualified Person in accordance with the guidelines of National Instrument 43-101 and is responsible for the program design and quality control of exploration undertaken by the Company on the Slick Rock program.
