RockBridge Resources Inc. (TSX VENTURE: RBE) has completed the summer prospecting of the Cross Hills Newfoundland Rare Earth and Copper property, and all samples have been sent to Activation Laboratories in Ontario for analysis. Accordingly, RockBridge is now proceeding with its plans for drilling to commence upon award of the contract.

In addition, RockBridge has been successful in application for a Government of Newfoundland and Labrador Department of Natural Resources Mineral Incentive Program Junior Exploration Assistance Grant which is designed to defray 50% of approved eligible costs, to a maximum grant of $100,000.

RockBridge President, Gary Mathiesen, stated "There are similarities between the geology, age and mineralization findings of our property and that of the major deposits in Saudi Arabia which suggests some potential for major Rare Earth Element mineralization. With China supplying more than 95 per cent of the global output of rare earth oxides while sitting on nearly 60 per cent of the world reserves, and cutting export quotas for Rare Earth Elements by 72%, the tightening of supply regulations obviously provides additional motivation as we prepare to drill in the coming weeks."

RockBridge Resources Inc. (TSX VENTURE: RBE) announces as part of its 2010 work program on its Cross Hills property, the commencement of the summer prospecting program, and the expansion of the Cross Hills property. The Cross Hills property now consists of 100% interest in 343 mineral claims covering 20,923 acres, prospective for Rare Earth Elements and metals and for Copper.

RockBridge Resources Senior Vice President, Adrian Van de Mosselaer, along with RockBridge's geologists and prospectors inspected the Cross Hills property late last week to kick off a 10 day focussed prospecting program. The results from this program will establish targets for drilling later this summer.

RockBridge met with the Mayor and council of Grand Le Pierre, the town situated within the Cross Hills property, and received tremendous support. New information and potential new claims were identified which has lead RockBridge to expand its Cross Hills property. Three new claim areas have been registered. One area consists of 10 claims covering 610 acres near Little Harbour East, across the harbour from Cross Hills, encompassing a coastal area known to locals as "Blue Rocks". The second area of 11 new claims expands RockBridge's Cross Hills property 671 acres to the south to fully encompass the coastal portion of the property, and an area know to locals as "The Mine", which was prospected for Gold many years ago. The third consists of 18 claims of 1,098 acres extending RockBridge's property in the north east to encompass a visible large quartz vein.

Photos of the new claim areas, and prospecting activity are available on RockBridge's web site at http://www.rockbridgeresources.com/projects.cfm.

RockBridge President, Gary Mathiesen, commented, "RockBridge would like to thank the people of Grand Le Pierre for their generous assistance and support. It is because of the support of the community leaders that RockBridge has been able to identify some very interesting targets for prospecting. We look forward to the completion of the summer prospecting program, the commencement of drilling later this summer, and increased involvement in the community."
