June 17, 2010

FOR IMMEDIATE RELEASE

• GRAVITY SURVEYS NEARING COMPLETION

• DRILLING AND ENVIRONMENTAL PERMITS APPROVED FOR 32 HOLE EXPLORATION PROGRAM

• DRILL CREW ASSEMBLED – TEAM TO BE LEAD BY RAY SPANJERS

• RC DRILLING CONTRACT SIGNED AND EXPECTED TO COMMENCE SHORTLY

Toronto, Ontario, June 17, 2010: Rodinia Minerals Inc. (“Rodinia” or the “Company”) (TSX-V: RM; OTCQX: RDNAF), is pleased to announce the advancement of its exploration program at its Salar de Diablillos lithium-brine project in Salta, Argentina (“Diablillos”). “We are encouraged by our ability to define a high-grade lithium-potash zone with our auger drill exploration program and are excited to commence the next phase of exploration at Diablillos” remarked William Randall, President and CEO of Rodinia. “Starting our first standard reverse circulation ("RC") drill program at Diablillos marks another key milestone for the Company and one, we anticipate, may provide significant support in establishing a NI 43-101 compliant resource estimate for the property.” (See Press Releases dated March 1, April 20, and May 26, 2010 for auger drill results at Diablillos).

Rodinia has engaged Quantec Geoscience Argentina S.A., a subsidiary of Quantec Geoscience Ltd. of Toronto, Canada to conduct a gravity survey of the Diablillos property and the Company anticipates receiving this analysis before finalizing the initial drill targets.

In addition, the Company has awarded the contract for drilling at Diablillos to Compañia Argentina de Perforaciones S.A., a reputable drill supply and contracting company in Argentina. The mobilization of the drill is expected to commence shortly. All drilling and environmental permits in support of the drill campaign are in place, as are access agreements with surface land holders.

Raymond P. Spanjers, MSc. (Geologoy), Rodinia’s Manager of Exploration will be running the drill program at Diablillos. Mr. Spanjers, a licensed Professional Geologist, has 29 years experience in industrial mineral exploration, plant and mine management. Prior to joining Rodinia, Mr. Spanjers spent 10 years with FMC Lithium Division where he explored for lithium brine deposits in Nevada and the Andean Puna of Argentina to identify potential production sites. Mr. Spanjers has also spent time exploring for and mining lithium deposits of spodumene pegmatites in the King’s Mountain Belt of North Carolina. He also oversaw the Company’s last drill campaign on its Clayton Valley Project in Nevada, USA.

Mr. Spanjers and his team in Argentina will explore across the entire salar with up to 32 drill holes using a standard RC drill rig. It is anticipated that initial drill targets will be prioritized based on an extensive review of the previously completed auger drill samples and the gravity survey to be received from Quantec Geoscience. The Company anticipates drilling under this program to occur to depths between 50 and 250 metres.

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 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.
