Q: Investorideas.com

1. Lithium batteries currently are used in cell phones and PC's and other applications - can you explain to investors the role lithium batteries will play with electric vehicles?

A: Mr. Guillermo Trias

Lithium ion batteries are becoming the best choice for electric vehicles, among other reasons, because lithium-ion stores three times the amount of energy and is much lighter than existing competing technologies.

Phase 2 drilling by Tasman intersects thick intervals of heavy rare earth elements and highest grades of zirconium at Norra Karr, Sweden

Including 43.7m averaging 0.70% TREO, 1.7% ZrO2 with 48.3% HREO

Tasman Metals Ltd. ("Tasman" or the "Company") TSXV - TSM; Frankfurt - T61; Pink Sheets - TASXF. Mr Mark Saxon, President and CEO, is pleased to provide assay results from a further five (5) drill holes that test the Company's 100% owned Norra Karr rare earth element (REE) - zirconium (Zr) project in Sweden. All drill holes intersected REE-Zr mineralization, with mineralized widths in one hole exceeding 100m, and two holes terminating in mineralization at a vertical depth of approximately 110m.

This set of results are the first of the Phase 2 program as announced 31st March 2010, which was drilled immediately after Phase 1 due to the success of the initial drilling at Norra Karr. Results from 20 drill holes have now been released, with these new drill holes located on two infill sections each spaced 200m from the sections previously reported.

RockBridge Announces Two New Mineral Discoveries

RockBridge Resources Inc. (RockBridge) (TSX VENTURE: RBE) is pleased to announce the results of sample analysis resulting from saw cut sampling of the #12 and other historic showings along with additional sampling from its Cross Hills Newfoundland property. This prospecting program was performed to better delineate the known zones of mineralization, locate any historic zones that could not be identified during the prior field investigation and identify additional mineralization on the property. The main historic target coordinates were sampled by channel cuts and representative grab sampling. Anomalous values were encountered however historic results could not be reproduced. During the prospecting program two material new mineral discoveries were made.
