Oct 19, 2012 - Rainbow Samples 2.51 OZ/T AU, 2.06 OZ/T AU and 0.86 OZ/T AU at Big Strike Project

TORONTO, ONTARIO, October 19, 2012:  Rainbow Resources Inc. (TSX VENTURE: RBW) ("Rainbow" or the "Company") is pleased to report that while its 2012 Big Strike Project drilling is focused on the high priority International and Gold Viking properties, the Company continues to identify highly prospective areas elsewhere throughout its 13,000-hectare land package (100% owned) in the West Kootenay region of southeast British Columbia. 

Two grab samples from a trench exposing numerous quartz veins in a mafic host rock (diorite) at the Whitewater Property near Nelson returned 2.06 oz/t Au (64.1 g/t) and 0.86 oz/t Au (26.9 g/t).  The samples were taken from different veins 30 metres apart and have been re-submitted for total metallics analysis.  This part of the Whitewater property, a former underground producer, has seen little exploration other than an access road and trench.     

Meanwhile, a sample containing quartz with banded tourmaline from a trench at the Referendum Property, also in the Nelson Gold Camp, has returned 2.51 oz/t Au (78.1 g/t).  It too is being reviewed using total metallics analysis.  At another area of this past producing property, a copper stained occurrence discovered recently by a Moose Mountain Technical Services geologist along a deactivated logging road has assayed >10000 ppm Cu (>1% Cu). 

Rainbow cautions that these samples, while highly encouraging, may not necessarily be representative of mineralization on each of the properties.

While drilling proceeds at Gold Viking, extensive prospecting continues at various Big Strike properties including the recently drilled International Silver Property in an effort to uncover additional high priority potential discovery areas.  Results will be released as soon as they are received and reviewed by Moose Mountain Technical Services, Rainbow's resource consultants. 

Meanwhile, drilling preparations are advancing at Jewel Ridge in Nevada, contiguous to Barrick Gold's Ruby Hill Mine.  Rainbow's Phase 1 program will focus on the former producing Hamburg Pit where one of the most recent historical results included 2.1 g/t Au over 39.6 metres near-surface.
