TORONTO, ONTARIO -- (Marketwire) -- 06/29/10 -- Rodinia Minerals Inc. ('Rodinia' or the 'Company') (TSX VENTURE: RM)(PINK SHEETS: RDNAF)(OTCQX: RDNAF), is pleased to report that as of market open tomorrow, Wednesday, June 30, 2010, the Company's shares will commence trading on the TSX Venture Exchange under its new name, 'Rodinia Lithium Inc.' The Company previously received shareholder approval for the name change at its Annual General Meeting held on June 10, 2010. The Company's ticker symbols remain unchanged as 'RM' on the TSX Venture and 'RDNAF' on the OTCQX.

In addition, the Company is pleased to report the mobilization of a reverse circulation ('RC') drill rig to its Salar de Diablillos ('Diablillos' or the 'Salar') property. The RC drill and other equipment are setting up on site and drilling is expected to commence this week. All applicable environmental permits and access agreements with surface land holders are in place. Rodinia has established a field camp on the Salar to service the program and ensure efficient work and timely results. Raymond P. Spanjers, MSc. (Geology), Rodinia's Manager of Exploration, and two local geologists who will oversee the drilling program, are on site.

As outlined in the Company's Press Release of June 17, 2010, the drill program will explore across the entire salar with up to 32 drill holes. The Company is finalizing its initial drill targets based on a prioritization of data received from its previous auger drill exploration program and gravity survey results from Quantec Geoscience Argentina S.A., a subsidiary of Quantec Geoscience Ltd. of Toronto, Canada. Rodinia anticipates drilling under this program to occur to depths between 50 and 250 metres. The Company anticipates that results from this drill program will assist to establish a National Instrument 43-101 compliant resource estimate for the Diablillos property.

William Randall, President and CEO, remarked, 'The mobilization and startup of our first RC drill program at Diablillos marks a key milestone for the Company and we are excited to get the drill turning. We have developed an extensive program based on a systematic analysis of the data received from gravity surveys and our recently completed auger drill exploration holes. We have prioritized targets for drilling and are prepared to commence the program.'

All exploration and drilling initiatives undertaken by Rodinia are supervised by William Randall, MSc. (Geology), the President and CEO of Rodinia. Mr. Randall is a qualified person, as defined by National Instrument 43-101, and he has reviewed and approved the scientific and technical information in this release. According to the Company's sampling protocol, sample size is to exceed 300 milliltres and be stored in clean, secure containers for transportation. The prepared samples are then forwarded to the ALS Laboratory Group, Environmental Division, in Fort Collins, CO (USA) for analysis. A rigorous QA/QC program is implemented consisting of regular insertion of standards and blanks to ensure laboratory integrity.
