Portal Provides Update on Bigwave Farm-In Agreement

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/12/11 -- Portal Resources Ltd. (TSX VENTURE: PDO) ('Portal' or the 'Company') announced on September 21, 2010 that it executed a binding Term Sheet, signed by all of the Bigwave Joint Venture ('JV') partners, giving the Company the right to increase its working interest, on a progressive basis, up to an average of 70% in certain lands owned by the JV. In the ensuing time since that announcement the Company has worked diligently to prepare a definitive Farm-in Agreement (the 'Agreement') in accordance with the terms of the Term Sheet that is acceptable to all partners. To date the Company has not been able to secure a unanimous consensus on this Agreement. While Portal's management team remains optimistic as to a conclusion to this matter there can be no assurances that a final document will be executed.

'Despite the fact that we have been unable to conclude the definitive Farm-in Agreement we have not been idle. We are continuing to review additions to the management team as well as acquisitions of both exploration and production assets,' stated David Hottman, Chairman and CEO.

The Bigwave Joint Venture consists of 17.75 sections (11,360 acres) of land, targeting light sweet oil. The Company will utilize the technological advancements in Horizontal Drilling and Multi-Stage Fracing to produce oil and gas. The first horizontal well has been drilled and requires a multistage frac as part of the completion.

Portal Resources Ltd. has offices in both Calgary and Vancouver, Canada and is focused on the exploration, development and exploitation of oil and gas resources in North America. Please refer to the Company's website at www.portalresources.net for additional information.

Portal is involved in the exploration for hydrocarbons and all of its current property holdings are in the grassroots or primary exploration stage. Exploration for hydrocarbons is a speculative venture necessarily involving substantial risk. There is no certainty that the expenditures incurred on Portal's exploration properties will result in discoveries of commercial quantities of hydrocarbons. Portal's future success in exploiting and establishing a reserve base will depend on Portal's ability to raise funds to develop its current properties and on its ability to discover hydrocarbons and acquire properties or prospects that are producing. There is no assurance that Portal's future exploration and development efforts will result in the discovery or development of commercial accumulations of oil and natural gas.

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
