Rodinia Minerals Inc. Reports Initial Sample Results At Diablillos With Brines Up To 890 Mg/L And An Average Mg:Li Ratio Of 2.57

Toronto, Ontario, March 1, 2010: Rodinia Minerals Inc. (“Rodinia” or the “Company”) (TSX-V: RM; OTCQX: RDNAF), is pleased to report that it has received positive initial sample results from its auger drill exploration program on its Salar de Diablillos lithium-brine project in Salta, Argentina (“Diablillos”).  The Company believes the initial results may be indicative of high concentrations of lithium and potash.

Results from the initial sampling of brines have returned lithium (“Li”) values of up to890 milligrams per litre (“mg/L”) and favourable magnesium (“Mg”) to lithium ratios.  The samples taken from within aquifers on the Diablillos property averaged 858 mg/L Li and 2.57 Mg:Li ratio.  These samples are from aquifers that will be the focus of subsequent exploration programs and to assess the feasibility of production in the future.  The results from aquifer sampling are summarized in the table below.

A sampling procedure was established to ensure sample integrity by minimizing contamination of brine samples by the dissolution of overlying sediments and evaporates that may be enriched in lithium.  Where possible, holes were drilled to three metres depth in an attempt to penetrate the overlying clay layer, which varies in thickness between one and over three metres.  Below the clays, a medium to coarse grained sand aquifer was encountered containing high-grade lithium brine in its porous space.  A historical drill hole in the south eastern margin of the salar indicates the presence of this aquifer to a vertical depth of at least 75 metres, with material coarsening at depth to a coarse basal conglomerate (SEGEMAR; www.segemar.gov.ar).

Sample integrity was maintained by pushing four inch casing down into the hole and pumping, where possible, the contents of the hole.  The hole was then left to refill from the aquifer below, ensuring proper representation of brine geochemistry.  This brine was then sampled and decanted before collection in sealed plastic containers that had been previously rinsed in the same brine.  All samples were sent to ALS Laboratory Group, Environmental Division, in Fort Collins, CO, USA where Rodinia is sending both its Diablillos and Clayton Valley project samples.

Rodinia’s auger drill exploration program is now being retooled to allow for exploration at depths to four-to-five metres.  The Company is encouraged by the results of the initial three metres program but believes that the nucleus of the salar has yet to be intersected.

The eight hole exploration program collected samples from various locations across the salar, comprising aquifer and surface water tests.  Surface water samples represent the concentrations present in waters that are presently feeding the salar.  The lithium values in these samples are encouraging as it shows that geothermal sources in the area are potentially lithium rich.  The surface sample results are summarized in the table below.

The project is supervised by William Randall MSc (Geology), the Vice President Exploration of Rodinia. Mr. Randall is aqualified 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 millilitres 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.

About Rodinia Minerals Inc.:

Rodinia Minerals 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 Diablillos project in Salta, Argentina.
