Aug 9, 2012 - Geophysical Data Outlines New Targets Over a 7-km Trend at International Silver Property

TORONTO, ONTARIO, August 9, 2012:  Rainbow Resources Inc. (TSX VENTURE: RBW) ("Rainbow" or the "Company") is pleased to report that the Company's prospecting and geological teams are immediately following up on freshly interpreted Fugro airborne geophysical data that has greatly expanded the zone of potential mineralization at the 4,000-hectare International Silver Property in the prolific West Kootenay region of southeast British Columbia. The first-ever drill program at the International is ready to begin.

The very prominent "Cabin" showing, a high-grade silver target in the central portion of the property where shallow drilling commences this coming weekend, is along the edge of a resistivity high that trends NW/SE through the property.  Moose Mountain Technical Services, Rainbow's resource consultants, reports that similar geophysical responses to those seen in the Fugro data for the "Cabin" area, and for the "Forgotten" showing 1,000 metres to the north, exist over a substantial portion of the northwest trending structure for a total distance of 7 kilometres.

Following a significant high-grade silver discovery in the early 1900's, the B.C. government surveyed the International vein system in the 1930's over a true strike length of 1.2 kilometres.  Airborne surveys had never been previously carried out over the property, the largest holding in the Company's 13,000-hectare Big Strike Project.

Six high-priority locations along the 7,000-metre-long trend at the International are being investigated as this important new geophysical data is followed up on the ground.

For further information:  President David W. Johnston -  (403) 701-2781.
