RockBridge Resources Inc.: Major Expansion of Cross Hills Property

RockBridge Resources Inc. (RockBridge) (TSX VENTURE: RBE) is pleased to announce expansion of the Newfoundland Cross Hills property from 54 claims of 3,200 acres to 304 claims covering over 18,500 acres.

The additional 15,300 acres are adjoined to RockBridge's claims, surrounding the existing property to the south and west, and extending to the northeast. These new properties secure sites of highly anomalous Rare Earth Element till samples collected by the Newfoundland Geological Survey. In addition, these properties secure the rights to areas of particular magnetic and geological interest for Rare Earth and Copper mineralization similar to those of the discoveries announced in RockBridge's June 29, 2010 news release.

RockBridge President, Gary Mathiesen, stated, "Our two new mineral discoveries announced last week are evidence of this area's potential. We have been able to use our most recent assay results to guide us in securing property which contain features of interest. In addition, we are compiling a prospecting plan which will provide us with additional data required to precisely define our targets for drilling this fall."
