Rodinia Lithium Files Favourable Preliminary Economic Assessment Technical Report (ccnm)

TORONTO, ONTARIO--(Marketwire - Dec. 23, 2011) - Rodinia Lithium Inc. ("Rodinia" or the "Company") (TSX VENTURE:RM)(OTCQX:RDNAF) is pleased to announce that the Company has filed a National Instrument 43-101-compliant Technical Report dated December 22, 2011, effective as of November 8, 2011 entitled "NI 43-101 Technical Report Preliminary Economic Assessment Salar de Diablillos Project Salta, Argentina", prepared by SRK Consulting (U.S.) Inc. (the "Report") under the Company's profile on SEDAR at www.sedar.com. The Report contains a comprehensive sub-surface to end gate breakdown of Rodinia's Preliminary Economic Assessment ("PEA") on the 100% owned Salar de Diablillos lithium brine project ("Diablillos" or "Salar") located in Salta Province, Argentina, the results of which were announced in a press release dated November 7, 2011.

The Report includes:

• Detailed geological overview and sub-surface brine model
• Preliminary processing flow sheets and site layout
• Overview of connections to key infrastructure including, water, power and transportation
• Sensitivities of the project to changes in lithium carbonate price, operating and capital costs
• High level project development schedule

There are no material differences between the results announced in the press release dated November 7, 2011 and the final PEA.

PEA Highlights (all currency is US$, pre-tax)

The PEA outlines an operation producing 15,000 tonnes lithium carbonate ("LC") per year and approximately 51,000 tonnes of KCl ("potash") per year, projecting a 34% internal rate of return ("IRR") pre-tax and a $561 million pre-tax net present value ("NPV") at an 8% discount rate. The PEA also outline's Rodinia's available option to increase production to 25,000 tonnes LC and 85,000 tonnes potash per year. This increased production scenario generates a much higher pre-tax NPV estimate of $964 million, along with a pre-tax IRR of 36%. A summary of the key economic findings, as reported in the November 7, 2011 press release, includes:

The PEA is preliminary in nature, includes inferred brine resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the estimates of the PEA will be realized.

Rodinia's Salar de Diablillos lithium-brine project in Salta, Argentina, contains a recoverable resource of 2.82 million tonnes lithium carbonate equivalent and 11.27 million tonnes potassium chloride equivalent. The project contains a recoverable inferred resource of 952,553,000 m3 grading 556 mg/L lithium and 6,206 mg/L potassium. Throughout 2011, Rodinia will focus on continuing to develop the Diablillos project by completing additional drilling and advancing through scoping study.

The Company also holds 100% mineral rights to approximately 70,000 acres in Nevada's lithium-rich Clayton Valley in Esmeralda County, and is currently in the process of assessing the size, quality and processing alternatives of this deposit. The Clayton Valley project is located in the only known lithium-brine bearing salt lake in North America, and looks to represent the only new source for domestic lithium carbonate supply.
