Tournigan Announces Significant Increase in Curraghinalt Gold
Resource and Updated Resource for the Kuriskova Uranium Deposit
======================================================================
Vancouver, December 5, 2007 -- Tournigan Gold Corporation (TVC:TSX-V;
TGP:Frankfurt) announced today a significant increase in the gold
resource at its Curraghinalt property in Northern Ireland and a
reduction, in line with the company's published expectations, of the
uranium resource at its Kuriskova deposit in Slovakia.
Curraghinalt update
The new Curraghinalt estimate, prepared by independent consultant Micon
International Limited of Toronto, includes an indicated resource of
250,000 ounces of gold contained in 570,000 tonnes of material with an
average grade of 13.95 grams of gold per tonne, and an inferred
resource of 350,000 ounces of gold contained in 640,000 tonnes of
material with an average grade of 17.15 grams of gold per tonne based
on a cut-off of 6 grams of gold per tonne and a minimum vein width of 1
metre.
The previous estimate for Curraghinalt, prepared by independent
consultant John Tully of North Vancouver, B.C. was an inferred resource
of 262,000 ounces of gold contained in 527,700 tonnes of material with
a grade of 15.45 grams of gold per tonne based on a cut-off of 6 grams
of gold per tonne and a minimum vein width of 1 metre. There was no
indicated resource in the January 2005 estimate.

The inverse distance resource estimate is based on 264 drillholes
including 11,934 metres in 24 holes drilled subsequent to the Tully
estimate (January 2005). Hole spacing ranged between 30 to 100 metre
centres. The Micon estimate was prepared by Dibya Kanti Mukhopadhyay,
an Independent Qualified Person as defined by Canada's National
Instrument 43-101 policy for the disclosure of mineral projects.
Tournigan expects to file the complete study on SEDAR within 45 days.
"Results from the drilling program confirm that the mineralized
resource zone extends a further 300 metres to the southeast and remains
open," said Tournigan president James Walchuck. "Furthermore, the deep
drilling to the northwest confirms that all the primary resource veins
are present, and several new veins have been identified. A detailed
structural review has enhanced our understanding of the deposit
considerably. Moving forward we will be reviewing options including a
preliminary assessment and further drilling."
Kuriskova update
The new Kuriskova estimate, prepared by independent consultant A.C.A.
Howe of Berkhamsted, England, is an inferred resource of 36.29 million
pounds of uranium oxide (U308) contained in 5.1 million tonnes of
material with an average grade of 0.323% U3O8 based on a cut-off of
0.035% U3O8. The Main Zone portion of the inferred resource estimate
includes 30.92 million pounds U3O8 contained in 3.34 million tonnes of
material with an average grade of 0.421% U3O8. The A.C.A. Howe
estimate was prepared by Galen White, an Independent Qualified Person
as defined by National Instrument 43-101. Tournigan expects to file the
complete study on SEDAR within 45 days.
In terms of pounds of U308, the new estimate represents a reduction of
28.1% from A.C.A. Howe's previous inferred resource estimate in May
2007 of 50.5 million pounds U3O8 contained in 9 million tonnes of
material with a grade of 0.255% U3O8 based on a cut-off of 0.035% U308.
This is within the reduction range of 10% to 30% anticipated by
Tournigan in its October 24, 2007 news release.
"At this level Kuriskova remains a world-class uranium deposit," said
Mr. Walchuck. "While it's been difficult for shareholders awaiting this
restatement, we can now move forward with a clear understanding of the
project's development potential. The high grade main zone comprises the
vast majority of the resource and the average grade of the global
resource estimate has moved up by 26% to 0.323."

As previously disclosed, the new estimate incorporates an improved
geological understanding of the deposit and addresses modeling issues
identified in the prior resource estimate. The inverse distance
estimate includes results from 10 of 13 diamond drill holes drilled by
Tournigan at the Kuriskova deposit in 2006, three diamond holes drilled
by Tournigan in late 2005, and 13 relevant holes of the 52 historical
diamond drill holes drilled by previous government operators. The hole
spacing for this inferred resource ranged between 40 to 150 metre
centres.
"Our next step will be a new estimate, expected in mid 2008, that takes
into account a recently completed 26-hole, 9,825-metre 2007
exploration program at Kuriskova," said Joe Ringwald, Vice President
Technical Services for Tournigan. "We expect to begin disclosing assay
results from this program in January 2008, assuming the contracted
assay laboratory can process the drill core on schedule.
"We also expect that the next estimate will upgrade a significant
portion of the deposit to the indicated resource classification. Our
optimism is based in part on radiometric readings indicating that a
majority of the 26 drill holes have intersected uranium mineralization.
We are now correlating the radiometric readings with geochemical
results from historic drilling on the property."
Tournigan has engaged AMEC to conduct a Kuriskova Targeting Study
involving mine development concepts and environmental impacts. AMEC
will work in collaboration with Wismut Umwelttechnik GmbH (WISUTEC) of
Chemnitz, Germany. AMEC is one of the world's largest international
engineering and project management companies. WISUTEC is an expert in
mine rehabilitation, geotechnics, and industrial, mine, and drinking
water technology. Targeting studies are by nature highly conceptual
and, if used, normally pre-date scoping studies. They are used to limit
project options available and to establish whether or not a property
has sufficient merit to warrant further expenditure. The Kuriskova
Targeting Study is scheduled for completion early in 2008.

CAUTIONARY NOTES TO US INVESTORS CONCERNING RESERVE AND RESOURCE
ESTIMATES
Indicated Resources
This news release and analysis uses the terms "indicated resource". The
Company advises US investors that while these terms are recognized and
required by Canadian regulations, the SEC does not recognize them. US
investors are cautioned not to assume that any part or all of mineral
deposits in these categories will ever be converted into reserves.
Mineral resources that are not "mineral reserves" do not have
demonstrated economic viability. Disclosure of "contained ounces" is
permitted under Canadian regulations; however, the SEC normally only
permits the reporting of non-reserve mineralization as in-place tonnage
and grade.
Inferred Resources
This news release uses the term "inferred resources". The Company
advises US investors that while this term is recognized and required by
Canadian regulations, the SEC does not recognize it. "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 rare cases. US
investors are cautioned not to assume that any part or all of an
inferred resource exists or is economically or legally mineable.
The TSX Venture Exchange does not accept responsibility for the
adequacy or accuracy of this release.
