RockBridge Updates Projects

RockBridge Resources Inc. (TSX VENTURE: RBE) (RockBridge) reports that as part of its 2010 work program, a ten day prospecting program on the Cross Hills Rare Earth property in southern Newfoundland has been completed by its experienced prospecting team. Reconnaissance exploration of the property and detailed investigation of historic showings were the focus of the program. Traverses were performed across RockBridge's newly staked ground along with detailed sampling and channel sampling of the main showing. New areas of radioactivity were identified during the program along with areas showing interesting copper mineralization. Results of pending assays will determine the significance of historic and new areas for the focus of further work. All samples have been sent to Activation Laboratories for analysis and are pending results expected in June.

The Cross Hills work program may include further and more refined exploration as RockBridge works towards delineating possible drill targets for an initial drill program in the coming months.

On RockBridge's Pembina Cardium oil and gas properties in Alberta, work continues in preparation for the planned horizontal drilling program later this year. Horizontal drilling and multi-stage fraccing has greatly accelerated activity in the Pembina Cardium field, which has become a focal point for the industry in Alberta in 2010.

RockBridge President, Gary Mathiesen, stated, "RockBridge is very pleased with the continuing thorough exploration being undertaken by its crews on the Cross Hills property and looks forward to the further results of the work program."
