Rodinia Minerals Inc. Provides Operational Update on Clayton Valley and Diablillos

TORONTO, ONTARIO--(Marketwire - Feb. 23, 2010) - Rodinia Minerals Inc. ("Rodinia" or the "Company") (TSX VENTURE:RM)(OTCQX:RDNAF) is pleased to provide an operational update on its Clayton Valley lithium-brine project in Nevada, USA ("Clayton Valley"), and on its Salar de Diablillos lithium-brine project in Salta, Argentina ("Diablillos"). "We are encouraged by the progress our team has made so far in 2010 at Clayton Valley and our ability to add to our land package at Diablillos," remarked David Stein, President and CEO. "In addition, the startup of the exploration program at Diablillos marks another key milestone for the Company." The Company anticipates drilling at both Clayton Valley and Diablillos will assist in establishing a NI 43-101 compliant resource estimate on both properties. The Company also anticipates it will be able to provide additional updates to this effect in the coming weeks.

Clayton Valley Project, Nevada, USA

The previously announced drill program at Clayton Valley (see Press Release dated December 8, 2009) is progressing with four holes completed to date, and a fifth hole on the western margin ready to be re-drilled now that additional casing has arrived at site. Both the eastern and southern claim packages have been tested with two holes each, with the second hole on the southern block currently underway at a depth of 1,500 feet. The technical difficulties encountered in the previous drill campaign have all been resolved, and two holes have successfully reached the basement floor.

Commenting on the drill program at Clayton Valley, William Randall, Vice President Exploration stated, "The drilling is progressing as planned. To date, we have encountered specific gravity and salinity values in discrete, clay bounded aquifers, which through comparative and relative analysis, are consistent with our understanding of rich lithium mineralization. Assaying for lithium is in progress and we anticipate being able to report initial results within the next two weeks to a month."

The Company is also in receipt of a gravity survey with results indicating that basin depths within the Clayton Valley are at their deepest within Rodinia's current claim package. "These deeper areas have the potential to host denser lithium-rich brines as they migrate due to gravitational setting," noted William Randall, (see Figure 1 below for additional details).

"Based on these preliminary findings, and the success of our new technical processes, Rodinia is in the process of staking additional land in Clayton Valley," added David Stein.

Diablillos Project, Salta, Argentina

Through a series of private transactions, Rodinia has expanded its current land package in the Salar de Diablillos to 5,756 hectares, such that the Company now owns the entire nucleus of the salar (see Figure 2 below for additional details). "These additional acquisitions provide a significant strategic advantage to Rodinia, as unlike many other lithium-brine operations, we now control a complete salar in Diablillos, as opposed to sharing the salar with other operators," stated David Stein. "We continue to evaluate opportunities in the area, including the potential to acquire additional land around the margin of the salar."

In addition to the increase in land package, Rodinia has commenced an initial auger drill exploration program at Diablillos. The program will use a two hundred by two hundred meter grid to ensure proper representation of the brine resource and will target brines from sand aquifers below the initial clay layer on the property. Holes are expected to vary in depth between two and four meters, with samples being sent to the ALS Laboratory Group in the USA for analysis. "We anticipate being able to report initial results within the next month," said William Randall.

Management has devised a procedure to ensure sample integrity by minimizing the contamination from external sources and has implemented a full QA/QC protocol that includes blanks and standards.
