Rodinia Minerals Inc. Enters Into Definitive Agreement and Samples Brines Up to 950 ppm and an Average Mg:Li Ratio of 1.4 at Salinas Grandes

TORONTO, ONTARIO--(Marketwire - Dec. 1, 2009) - Rodinia Minerals Inc. ("Rodinia" or the "Company") (TSX VENTURE:RM), reports positive results from its due diligence review and has entered into a definitive agreement (the "Definitive Agreement") with a private party in Argentina with respect to the previously announced acquisition of approximately 4,500 hectares of the Salar de Salinas Grandes, located in the Province of Jujuy, Argentina (the "Salar de Salinas Grandes")(See Press Release dated October 30, 2009). Pursuant to the terms of the Definitive Agreement, Rodinia is required to make cash payments in the aggregate of USD$900,000 over the next two years, of which USD$150,000 is payable upon entering into the Definitive Agreement.

Results from sampling of brines during the thirty days of due diligence have returned excellent lithium ("Li") values, with numbers as high as 950 parts per million ("ppm") and extremely favourable magnesium ("Mg") to lithium ratios. The samples taken from within aquifers on the Salinas Grandes property averaged 440 ppm Li and 1.4 Mg:Li ratio.

A total of five samples were collected from various locations across the salar, comprising surface water and aquifer tests. Surface water samples represent the concentrations present in waters that are presently feeding the sub-surface aquifers. The high lithium values in these samples are encouraging as it shows that geothermal sources in the area are extremely lithium rich. The sub-surface samples were collected from aquifers below a laterally extensive impermeable clay layer. These samples are from aquifers that would be the focus of subsequent exploration programs and possible producers. The results are summarized in the table and map below.

An exploration program following up on these positive results is currently being devised. The program is currently thought to consist of surface geophysics, including gravity and TEM, in conjunction with extensive sampling of the near surface aquifers. A systematic grid will be employed to allow for proper characterization of the lithium-rich brines.
