Tournigan's Arizona Breccia Pipes Indicate the Presence of Uranium

VANCOUVER, BC -- (MARKET WIRE) -- March 6, 2007 --Tournigan Gold Corporation (TSX-V: TVC) (FRANKFURT: TGP) is pleased to report that anomalous pathfinder elements indicating the possible presence of uranium have been found at surface, over 22 breccia pipes in the northern Arizona Strip uranium district. Especially significant are six anomalous uranium samples collected from five breccia pipe targets. Five samples contain 17 to 53 parts per million (ppm) uranium, and a sixth sample, collected from annular faulting (see attached diagram) contains 1,240 ppm uranium. Other significant pathfinder elements found over breccia pipe targets include copper, lead, zinc, silver, arsenic, barium, chromium, molybdenum, nickel, and vanadium. Follow-up radiometric work conducted over the anomalous structures has defined twenty-two high priority targets. Drilling of the priority targets is scheduled to begin during the second quarter of 2007.

Collapse breccia structures containing strongly anomalous pathfinder element concentrations in outcrop are significant because all known breccia pipe-hosted uranium deposits in the Arizona Strip area of the Colorado Plateau are known to contain pathfinder element mineralization on surface, associated with breccias or annular faulting. Energy Fuels Nuclear produced over 19 million pounds of U3O8 (uranium oxide) from 7 mines in other breccia pipes during the period 1980 - 1991. The average ore grade of those pipes, 0.65 % U3O8, is high when compared with other uranium deposits worldwide.

"Tournigan has successfully identified anomalous uranium and associated pathfinder elements in nearly 33 percent of the 65 breccia pipe targets investigated as part of its initial reconnaissance exploration program conducted on its Arizona Strip properties," said James Walchuck, President and CEO of Tournigan. "Follow-up work on 22 high priority targets, including focused ground geophysics, is currently underway. Tournigan has staked some highly prospective uranium properties in Arizona, Wyoming and South Dakota during the last couple of years. Initial results from the Arizona properties seem to indicate that a new frontier of uranium exploration could open up for the Company."

Uranium in the Arizona Strip is hosted in breccia pipes which were formed by the collapse of overlying strata into karstic-limestone solution cavities in the Redwall Limestone Formation, creating roughly cylindrical, near vertical columns of broken (brecciated) rock. Breccia pipes typically range from 100 feet to 400 feet in diameter and can have a vertical dimension up to 3,000 feet. Uranium mineralization is found within the pipes at a stratagraphic interval coincident with the Permian Coconino Formation and Hermit Formation.

Tournigan maintains 54 claim-blocks covering more than 80 prospective breccia pipe targets. Exploration, conducted from June - September 2006, consisted of reconnaissance geologic mapping and the collection of 13 soil samples at each of 65 targets. Multiple pathfinder element anomalies were recorded in two or more soil samples from 16 targets. Follow-up work consisted of additional mapping, ground radiometric surveys and selective rock chip samples. Moderate to strong anomalous pathfinder element concentrations were identified on 22 targets. Pathfinder elements and their anomalous ranges are listed below.
