TORONTO, ONTARIO, August 24, 2012:  Rainbow Resources Inc. (TSX VENTURE: RBW) ("Rainbow" or the "Company") is pleased to report that a Phase 1 diamond drilling program at the Company's 100%-owned International Silver Property in southeastern British Columbia is reaching targeted depths of 100 to 130 metres, intersecting highly deformed quartz-mica schist/gneiss as expected.  Initial drilling is focused on an exposed quartz dominated structure featuring disseminated to massive galena, pyrite and rare sphalerite.  Drill core is being logged, split and sent in for assaying using multi-element analysis in testing for silver, gold, lead and zinc mineralization.

The number of drill site locations is being increased and an additional drill program update will follow in the near future.  Moose Mountain Technical Services, Rainbow's resource consultants, are overseeing this first-ever drill program at the International Property.

The exploration target at the International is a high-grade, near-surface silver deposit.
