Tournigan Updates Progress on Prefeasibility Study for Kuriskova

Tournigan Energy Ltd. (TVC: TSX-V; TGP: Frankfurt) (Pink Sheets: TVCFF)continues to advance an NI 43-101 compliant prefeasibility study for
its Kuriskova uranium project in Slovakia. Tetra Tech, Inc. of Golden,
Colorado is preparing the study, expected to be completed in December
2011.

Tetra Tech′s proposed mine production plan for Kuriskova will be based
on the Indicated portion of the most recent resource estimate. The April
2011 resource estimate comprises an Indicated Resource of 28.5 million
pounds U₃O₈ grading 0.555% U₃O₈
contained in 2.3 million tonnes and an additional Inferred Resource of
12.7 million pounds U₃O₈ grading 0.185% U₃O₈
contained in 3.1 million tonnes, at a cut-off of 0.05%U (see news
release dated April 26, 2011 announcing the resource estimate prepared
by Tetra Tech). Ongoing metallurgical test work has confirmed uranium
recoveries of 93-94%.

All field work and data interpretation necessary for completion of the
prefeasibility study on schedule are in progress. Highlights of the work
include:

• 
  Completion of Phase 1 metallurgical test work at Hazen Research. Phase
  II is in progress;
  
• 
  Geotechnical studies: the third of five geotechnical holes is being
  drilled, with completion of the geotechnical drilling program expected
  by mid-September. Logging of oriented core is continuing and results
  are being interpreted;
  
• 
  Hydrogeological modeling: the three hydrogeological holes have been
  drilled and results are being interpreted;
  
• 
  Collection of environmental base line data, including water and soil
  sampling and analysis;
  
• 
  Preliminary engineering work for mine, process plant and
  infrastructure design; and
  
• 
  Capital and operating cost estimates.
  

The Phase 1 test work at Hazen has confirmed uranium and molybdenum
leach recoveries of 93-94% and 90-93%, respectively, on Kuriskova
composites using a conventional alkaline leach circuit at P₈₀
200 mesh grind, 200^oC, and oxygen overpressure of 100 psi in
a two hour leach time. Phase 2, which is ongoing, is focusing on
refinement of the uranium and molybdenum precipitation parameters using
industry standard flow sheets for alkaline process plants.

In addition to advancing the Kuriskova prefeasibility study, Tournigan
is continuing with surface exploration work (geology, geochemistry and
geophysics) within the Kuriskova exploration licence and on the
company′s other exploration licences in Slovakia. This is expected to
lead to drill targets which the company will begin testing after the
Kuriskova geotechnical drilling is completed. Tetra Tech is also in the
process of preparing an NI 43-101 resource estimate for the Novoveska
Huta uranium deposit in Slovakia which is expected for release by the
end of September.
