Tournigan’s Prefeasibility Study Indicates Kuriskova Could Be Among World’s Lowest Cost Uranium Producers

Tournigan Energy Ltd. (TVC: TSX-V; TGP: Frankfurt) has received a Preliminary Feasibility Study (“PFS”) on its flagship Kuriskova high-grade uranium deposit located in Slovakia from its independent consultant, Tetra Tech, Inc. (Tt), in Golden, Colorado.

Highlights of the PFS for Kuriskova:
  • Internal Rate of Return 30.8%; 1.9 year payback; $277 million Net Present Value (NPV) at an 8% discount rate (Pre-Tax, base case US$68/lb U3O8, US$15/lb Mo);
  • 94% increase of Indicated Resource to 28.5 million pounds of U3O8 since Tournigan’s June 2009 Preliminary Economic Assessment (“PEA”);
  • 92% uranium recovery in PFS, increased from 90% in the PEA;
  • 62% increase in the uranium grade to the process plant to 0.408% U3O8 in the PFS from 0.252% U3O8 in PEA;
  • 26% lower life of mine operating costs in the PFS compared to the PEA. The PFS estimates US$22.98/lb U3O8 life of mine operating costs and US$16.68/lb U3O8 during the first 4 years of production. These are net of a molybdenum credit of about US$1.27 per pound of U3O8;
  • 1.5 year decrease of preproduction construction period in PFS to 3 years compared to 4.5 years in the PEA;
  • The project can be developed as an underground mine/processing facility with a very small surface footprint;
  • Kuriskova would utilize Best Available Technologies in the mining and processing operations. The uranium can be extracted using conventional alkaline (non-acid) processing; and
  • There are multiple exploration targets within the Kuriskova License area, with the potential to expand the resource base and extend project life.

“We are very pleased with these results. They demonstrate that the Kuriskova project has the potential to be among the lowest cost uranium producers in the world. The PFS not only illustrates the robust economics of the Kuriskova project but also the competitive advantages it has over other uranium projects as a result of its high-grade resource and relatively low operating cost estimates.” said Dorian L. (Dusty) Nicol, Tournigan’s president and chief executive officer.

“Our next step is, working with our strategic partner Areva, to begin a Feasibility Study and Environmental Assessment Study that will continue to define project parameters to a higher degree of confidence and allow the permitting of the project to begin. The development of the Kuriskova uranium project could provide Slovakia with a secure source of uranium for approximately 30 years at its current consumption rate,” said Nicol.

Mineral Reserves and Resource Estimate

The PFS resource estimate is based on the report, “Mineral Resource Update Kuriskova Uranium Project East-Central Slovakia” prepared by Tetra Tech, Inc. dated June 9, 2011 (the Independent Qualified Person for this report was Dr. Rex Bryan of Tetra Tech) as summarized in the following table:

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

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

Based on estimated Indicated Resources, mineral reserves (including dilution tonnage of 5% at a grade of 0.03% U) were estimated at 2.5 million tonnes at an average grade of 0.346%U which was determined to provide an underground mining rate of about 210,000 ore tonnes per year at an economic cutoff of 0.13% U 3O 8 for approximately 13 years. No Inferred resources were used in reserve calculation or mine plan.

Resource Expansion Potential

Tournigan is planning an exploration program to continue testing multiple uranium exploration targets within the Kuriskova license area. Exploration success would likely add resources that could be accessed from the planned Kuriskova infrastructure. Tournigan will conduct further step-out exploration drilling where the high-grade mineralization is open along strike and at depth.

Mining and production

The PFS states that the project would be best developed as an underground mine using conventional mining and processing methods. The mine plan is based on underhand drift and fill mining utilizing a roadheader as the primary production method and assuming an external dilution (over break) of 5% at a grade of 0.03% U.

The project would be designed with an underground processing facility. As a result of the mining and processing facilities being underground, the project can be developed with a very small surface footprint. The uranium can be extracted using conventional alkaline (non-acid) processing. Kuriskova would utilize Best Available Technologies in the mining and processing operations.

Metallurgical test results completed at Hazen Research in Golden, Colorado indicate that uranium and molybdenum recoveries can be achieved using conventional alkaline leaching and precipitation circuits producing separate uranium (yellowcake) and molybdenum concentrates.

The average annual production of uranium as a U 3O 8 concentrate would be approximately 786 tonnes and 84 tonnes of molybdenum in molybdenite with a life-of-mine U 3O 8 production of 20.9 million pounds (9,500 tonnes). Project economics in the base case analysis are based on these figures.

Metallurgy and Processing

Metallurgical test results completed at Hazen Research in Golden, Colorado indicate that uranium and molybdenum recoveries of 92.0% and 86.8%, respectively, can be achieved using conventional alkaline leaching and precipitation circuits producing separate uranium (yellowcake) and molybdenum concentrates.

Financial Analysis

The base case uses forward prices of US$68/lb U 3O 8 and US$15/lb Mo respectively.

Initial capital costs are US$225 million (including owner’s costs and a contingency of US$31 million). During the life of mine there will be sustaining capital requirements of about US$71 million.

Total operating costs are estimated to be US$22.98 per pound of U 3O 8 over the mine life. During the first 4 years of production, total operating costs are estimated at US$16.68 per pound of U 3O 8. These costs are net of a byproduct credit for molybdenum of about US$1.27 per pound of U 3O 8.

In addition to adding value to the Kuriskova project, molybdenum has been defined as a Class 2 strategic metal by the European Union. Royalties payable to the government in this base case will add about US$2.89 per pound of U 3O 8.

The base case internal rate of return is estimated at 30.8% on a pre-tax basis with a 1.9 year payback after the start of production on an estimated initial capital cost of US$225 million including owner’s costs and a contingency of US$31 million.

At an 8% discount rate, the pre-tax NPV is estimated at US$277 million. The project is financially sensitive to U 3O 8 price and amount of uranium produced per year. This is directly related to the tonnage and grade mined and processed annually as well as to plant recovery.

The following tables illustrate the sensitivity of the project to changes in U 3O 8 price and discount rate used in the NPV calculation:
 
Uranium (U3O8) Price Sensitivity
Economic Parameter   -10%   Base Case   +10%
  ($61.2)   ($68.0)   ($74.80)
NPV   $201.2   $276.8   $352.4
IRR   25.7%   30.8%   35.4%
 
Discount Rate Sensitivity
NPV 0%   NPV 5%   NPV 8% Base Case   NPV 10%
$618.3   $374.2     $276.8   $225.7
All dollar values are in US$ millions.
