Rodinia Lithium Inc. Announces Increased Resource Potential at Salar de Diablillos Based on Independent Gravity Survey

TORONTO, ONTARIO–(Marketwire – Sept. 29, 2010) – Rodinia Lithium Inc. (“Rodinia” or the “Company”) (TSX VENTURE:RM)(OTCQX:RDNAF), is pleased to report that it has received the results from a gravity survey covering its Salar de Diablillos lithium-brine project in Salta, Argentina (“Diablillos” or the “Salar”). The gravity survey was completed by Quantec Geoscience Argentina S.A., a subsidiary of Quantec Geoscience Ltd. of Toronto, Canada. The gravity survey allows for the estimation of basement depth and potential aquifers contained within the basin, and will be an invaluable tool during the resource estimation process.

William Randall, President and CEO of Rodinia, commented “The results from the gravity survey are extremely encouraging, as they define a basin capable of hosting potentially significant resources of lithium, potash, and boron. We are pleasantly surprised to find that the basin extends further north than anticipated, beyond the visible Salar surface, and to note that the deepest parts of the basin remain untested. Given the positive drill results announced September 17, we feel confident in the economic potential of this deposit given the depth and extent of the inferred aquifers” (see Press Release dated September 17, 2010 for additional details on drill hole D-RC-01).

The gravity survey results show basement depths that exceed 390 metres from the Salar surface and suggest an extension of the potentially mineralized horizons further north beyond the Salar surface by an additional 2.0 kilometres.

The results estimate the deepest portion of the basin, with depths approaching 400 metres, to be in the northern and north-eastern region of the Salar. This region coincides, in part, with the high-grade zones defined on surface (see Press Release dated September 24, 2010 and Press Release dated May 26, 2010) and indicates that reverse circulation drill hole D-RC-01 was drilled very close to basement depth. The deepest areas of the Salar have not yet been tested by the current drill program.

Results received from the gravity survey are being processed to produce an estimate of the basin volume and to aid in the current drilling program. The Company plans to release additional results as they become available.

All exploration and drilling initiatives undertaken by Rodinia are supervised by William Randall, MSc (Geology), the President and CEO of Rodinia, and by Ray Spanjers, Rodinia’s Manager of Exploration. Both Messrs. Randall and Spanjers are considered qualified persons, as defined by National Instrument 43-101, and Mr. Randall has reviewed and approved the scientific and technical information in this release.

About Rodinia Lithium Inc.:

Rodinia Lithium Inc. is a Canadian mineral exploration company with a primary focus on lithium exploration and development in North and South America. The Company is positioned to capitalize on the expected increase in demand for lithium carbonate that is projected to result from the anticipated paradigm shift to mass adoption and use of key lithium applications like lithium-ion batteries as well as glass ceramics, greases, pharmaceuticals etc.

Rodinia is currently exploring its Clayton Valley project in Nevada, USA, which surrounds the only lithium-brine producer in North America, and its Salar de Diablillos project in Salta, Argentina.
