Title: Tournigan Increases Indicated Resource at Kuriskova by 39% to 28.5 Million Pounds of U3O8

Vancouver, April 26, 2011 - Tournigan Energy Ltd. (TVC: TSX-V; TGP: Frankfurt) has updated its resource estimate for the Kuriskova uranium deposit in Slovakia. This NI 43-101 compliant updated estimate increases the amount of uranium contained in the Indicated Resource by 39% to 28.5 million pounds of U₃O₈ and increases the overall size of the deposit. Tetra Tech, Inc., the firm that is conducting the ongoing Prefeasibility Study on Kuriskova, has reviewed, audited and approved the updated resource estimate.

Highlights of the updated estimate include:

About 7.9 million pounds of U₃O₈ have been added to the Indicated Resource category, increasing the Indicated Resource by 39% to 28.5 million pounds of U₃O₈;
Overall the uranium oxide contained in the Kuriskova deposit has increased by 3.1 million pounds of U₃O₈ and now comprises 28.5 million pounds at 0.555% U₃O₈ in the Indicated Resource and an additional 12.7 million pounds in Inferred Resource at 0.185% U₃O₈; and
Kuriskova remains one of the highest grade known uranium deposits in the world outside of Canada's Athabasca Basin.

"We are confident that this Indicated Resource is of sufficient size and grade to be the basis of a Reserve for the Kuriskova Prefeasibility Study, which we expect to complete around the end of this year," said Dorian L. (Dusty) Nicol, Tournigan's president and CEO. "We expect the increase in high-grade resource to have a positive effect on overall project economics as compared to our June 2009 Preliminary Assessment (Scoping Study).

"We emphasize that we believe there remains significant exploration potential to increase the size of the Kuriskova resource both immediately adjacent to the current resource and in the surrounding exploration licence. This new resource estimate also continues to demonstrate the presence of a significant amount of molybdenum within the uranium resource, which could represent a significant by-product credit."

The following tables summarize the current and previous resource estimates:

Current Resource April 2011:

Kuriskova Resource Estimate April 2011 - Cut-off 0.05%U
	U%	Tonnes (000)	%U₃O₈	U₃O₈ lbs (000)	Mo%	Tonnes (000)	Mo lbs (000) *
Total Indicated (Main Zone, Hanging wall zone and Zone 45)	0.471	2,328	0.555	28,487	.065	2,301	3,312
Total Inferred (Main Zone, Hanging wall zone and Zone 45)	0.157	3,099	0.185	12,664	.033	2,996	2,185

* Mo resource numbers represent molybdenum associated with uranium resource blocks above a 0.05%U cutoff

The updated estimate incorporates the results of 18 diamond drill holes totaling 4,548 metres that were drilled since the last resource estimate previously disclosed in a news release dated March 24, 2010. The updated estimate also reflects enhanced understanding of Kuriskova geology which has allowed more detailed structural modeling than was done in the past. The estimate was prepared by Ravi Sharma, Tournigan's manager of resources and reserves, and reviewed, audited and approved by Tetra Tech, Inc., who is preparing an independent NI 43-101 compliant Technical Report which will be filed on SEDAR within 45 days of the date of this news release. Mr. John W. Rozelle, P.G., is Tetra Tech, Inc.'s Qualified Person (QP) for this updated report and is an independent Qualified Person as defined by NI 43-101.

Drill core samples are analyzed by ALS Chemex in Seville, Spain for chemical assay, under Tournigan's strict Quality Assurance/Quality Control protocols. Interpretation and outlining of mineralization was conducted section-by-section by incorporating geological, structural and assay information for each geological domain. The 3D wireframe solids of the previous resource estimate dated March 24, 2010 were updated with infill holes for the Main Zone South and new wireframe solids were created for Zone 45 based on step-out drill holes. The detailed structural interpretation was carried out for the deposit and structures controlling grades were modeled and incorporated; these were reviewed by Tetra Tech. Interpolation and NI 43-101 compliant resource classification parameters were reviewed by Tetra Tech.

Ravi Sharma, MAusIMM, Tournigan's manager of resources and reserves, and a Qualified Person as defined by NI 43-101, has reviewed and approved the technical disclosure contained in this news release. Tetra Tech, Inc. has also reviewed and approved the technical content of this news release.

Notice to US investors:
This press release uses the terms "indicated resources" and "inferred resources", which are calculated in accordance with the Canadian National Instrument 43-101 and the Canadian Institute of Mining and Metallurgy Classification system. We advise investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize them. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. In addition, "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in certain exceptional cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally minable.
