Rainy River Launches Ground Based Geophysical Surveys Designed to Penetrate Local Till Cover and Identify "Hidden" Massive Sulphide Bodies

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 10, 2007) - Nelson W. Baker, President of Rainy River Resources Ltd. (TSX VENTURE:RR) reports that the Company will be conducting test surveys of Quantec's Titan 24 DCIP/MT system as well as the newly developed InfiniTEM system from Abitibi Geophysics in an attempt to determine the signature of the various mineralization styles. Due to the thick overburden in Richardson Township, conventional ground based electromagnetic (EM) and electrical (IP) surveys have not been able to define the signature of the gold mineralization nor the massive sulphides hosted in the Cap Trend and the 34 Ni-Cu-PGE Zone.

The geophysical platforms that the Company will be utilizing are designed to "look deep" and to penetrate thick, conductive overburden that would hinder conventional geophysical survey systems. The surveys are not only designed to test the known mineralization, but also to explore outside the area that is currently being drilled in Richardson Township.

Surveying with InfiniTEM is scheduled to begin this month, and the Titan 24 DCIP and MT survey will be commencing in Q1 2008.
