VANCOUVER, British Columbia--(BUSINESS WIRE)--Tournigan Energy Ltd. (TVC: TSX-V; TGP: Frankfurt) (Pink Sheets: TVCFF) announces a resource estimate for its Novoveska Huta uranium project in Slovakia. This is the first NI 43-101 compliant resource estimate that has been prepared for this deposit; the estimate has been reviewed, audited and approved by Tetra Tech, Inc. The results of the resource estimate at a cutoff grade of 0.06% U are:
- 3.75 million pounds of U3O8 in Measured and Indicated Resources of 1.662 million tonnes grading 0.102% U3O8; and an additional
- 12.738 million pounds of U3O8 in Inferred Resources of 4.689 million tonnes grading 0.123% U3O8.
This resource adds to Tournigan’s 43-101 compliant uranium inventory. The Novoveska Huta uranium deposit is located near the town of Spisska Nova Ves, about 50 kilometres northwest of Tournigan’s high-grade Kuriskova uranium deposit. At Kuriskova, the most recent resource estimate (see news release dated April 26, 2011) comprises an Indicated Resource of 28.5 million pounds U3O8 at a grade of 0.555% U3O8 contained in 2.3 million tonnes and an additional Inferred Resource of 12.7 million pounds U3O8 at a grade of 0.185% U3O8 contained in 3.1 million tonnes, both estimates at a cutoff of 0.05% U. The Kuriskova Prefeasibility Study, being prepared by Tetra Tech, Inc. continues to progress on schedule, with completion expected by early in 2012.
“We are excited to add these pounds of uranium to our 43-101 compliant resource inventory so close to Tournigan’s flagship Kuriskova project,” said Dorian L. (Dusty) Nicol, Tournigan’s President and CEO. “We look forward to growing and advancing both properties.”
Tournigan’s objective at Novoveska Huta was to verify historic data, which was collected during Slovakia’s communist period, and to find additional resources. The western part of the deposit (currently comprising the Measured and Indicated Resource) was known before Tournigan acquired the property, but the data base had not been verified and underground sampling data had not been evaluated. Tournigan’s work in the western part of the deposit verified the historical data. In addition, Tournigan included underground channel sample data in the new resource estimate. Tournigan’s exploration drilling in the eastern part of the deposit confirmed the extension of mineralization to the east and increased the exploration potential of the deposit. The eastern block is at a higher grade than the western block and remains open to the east and north.
In addition to historical drilling and underground sampling data that could be verified, the Novoveska Huta resource estimate incorporates 17 diamond drill holes totaling 8,897 metres drilled by Tournigan between 2006 and 2011. These holes comprise 7 twin holes drilled to verify historical drill holes, 2 twin holes drilled to verify data from the historic shaft, 2 exploration holes drilled into the western block and 6 step-out holes (of which 5 were completed) that were drilled to explore and extend the deposit to the east.
Historical data at Novoveska Huta were compiled during Slovakia’s communist period. They comprise 106 surface drill holes (of which 38 were used in this resource estimate), 371 underground holes and 5.5 Km of underground development from which were taken 2,081 radiometric channel samples. Only data which could be verified and had backup of hardcopy stamped original documents were used in the resource estimation. Data verification was reviewed by Tetra Tech, Inc. The data base comprises eU % (gamma) for historic holes and U % (chemical assay) for Tournigan holes. Tournigan carried out closed-can analysis at Energy Lab, USA, to confirm that there are no disequilibrium issues between radiometric gamma and chemical assays.

*The resource estimate includes radiometric gamma for historic holes and underground development data and chemical assays for Tournigan drilling. Molybdenum resource numbers represent molybdenum associated with uranium resource blocks above a 0.06% U cutoff.
**All of the molybdenum resource is classified as Inferred because of the absence of molybdenum assays in historical data. For this same reason, not every uranium block in the resource is included in the molybdenum resource and therefore uranium and molybdenum resource tonnages do not correspond.

The estimate was prepared by Ravi Sharma, Tournigan's Manager of Resources and Reserves, and has been reviewed, audited and approved by Tetra Tech, Inc. Tetra Tech, Inc. 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. Dr. Rex Bryan is Tetra Tech's Qualified Person (QP) for this report and is an independent Qualified Person as defined by NI 43-101. This estimate is prepared in accordance to National Instrument 43-101 and classified as Measured, Indicated and Inferred according to the “CIM Standards on Mineral Resources and Reserves”.
A historical (not NI 43-101 compliant) P & Z3 (Slovak resource classifications, roughly analogous to Inferred) resource estimate prepared by former operator Uranpres (Jozef Daniel) in 2005 reported 19,970,000 pounds of uranium contained in 12 million tonnes at an average grade of 0.075% U308 (cutoff grade 0.015% U308) at Novoveska Huta (see Tournigan news release dated September 10, 2008).
Drill core samples from 17 drill holes drilled by Tournigan were analyzed by ALS Vancouver, SGS Lakefield and the SGUDS Laboratory in Slovakia for chemical assay between 2006 and 2011. The assays were conducted 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. The 3D wireframe solids were created using Datamine studio software. Block models within these mineralized 3D wireframe solids were interpolated using ordinary kriging. The estimate was reviewed by Tetra Tech, Inc. Interpolation and NI 43-101 compliant resource classification parameters were reviewed by Tetra Tech, Inc.

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.
