Curraghinalt

Curraghinalt Gold Deposit - Northern Ireland - 100% interest in licenses

Tournigan holds 100% of four licences spanning 838km2 in counties Tyrone and Londonderry, Northern Ireland. The property lies 127 km west of Belfast and 15 km northeast of Omagh. At Curraghinalt, previous operators identified gold-bearing quartz veins in a well defined mesothermal gold system. Tournigan started drilling the property in 2003 and released its latest resource estimate in Dec. 2007 as follows:

Curraghinalt Gold Resource Estimate
Micon 12/07 Tonnes Grade (gpt) Ounces
Indicated 570,000 13.95 250,000
Inferred 640,000 17.15 350,000
(Cut-off Grade 6 g/t au, > 1 metre thickness)


The resource estimate, disclosed in December 2007, is from a study prepared by independent consultant Micon International Limited of Toronto. The complete technical report in support of the resource estimate is available at this link: 43-101 Curraghinalt Technical Report (PDF, 4.26 mb)

The study incorporated results from a 24-hole, 11,934-metre drilling program conducted by Tournigan in 2006 and 2007. The drilling confirmed that the mineralized resource zone extends a further 300 metres to the southeast and remains open. 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 considerably enhanced Tournigan's understanding of the deposit.

In February 2008 Tournigan provided the results of a deep drill hole, CT-53, at its Curraghinalt gold deposit in Northern Ireland. The hole was not previously disclosed in the resource estimate announced December 5, 2007, as it was completed post deadline for resource evaluation.

CT-53, drilled to a depth of 501 metres, was collared northwest of the main resource zone and terminated over top of CT-26. It was drilled as part of an ongoing program of testing the down dip extension of the main resource. The hole intersected 16 mineralized veins including seven of particularly high grade. CT-53 returned similar vein grades and widths to those recorded in hole CT-26; the last deep hole in the deposit that was included in the December resource estimate.

Highlights include:

From To Width (m) g/t Au
57.25 58.25 1.00 9.0
78.37 79.37 1.00 9.7
165.64 166.64 1.00 18.1
175.58 176.58 1.00 10.6

Next Steps
Tournigan believes the 346 km² Curraghinalt property has substantial exploration potential and intends to continue adding to and upgrading the current inferred and indicated resource by conducting an active exploration program. In 2008 Tournigan will continue with an additional 2,500 metres of infill and exploratory drilling. The company expect to release a preliminary assessment on the deposit in the third quarter of 2008.

Access and Infrastructure

Highways, public roads, private roads and local farm tracks provide access to and within the property boundary. Within the property boundaries there are ample sources of water. A major power line sub-station is located at Plumbridge, approximately 9 km northwest of the property and roughly 6 km north of the village of Gortin. The claim block is sufficiently large for the location of mine infrastructure requirements such as mill and office buildings, waste dumps and tailings storage areas.

History

Tournigan acquired a 100% interest in the licenses containing the Curraghinalt deposit subject to a 2% net smelter royalty payable to Minco plc. Previous exploration at Curraghinalt in the 1980's and 1990's consisted of more than 17,000 metres of drilling and 697 metres of underground development work as well as extensive surface trenching. Since Tournigan began work in April of 2003, the company has completed a detailed project compilation and review of the historical database, performed underground mapping, structural analysis, soil geochemical surveys, in-fill and step-out drilling and limited geophysical surveys over the entire Curraghinalt vein system.

This work upgraded the confidence of the resource and identified mineralization that extended the known high-grade gold mineralization to twice the previously documented depth. In addition numerous other promising targets have been identified that may expand the currently defined resource.

Geology

Curraghinalt is a high-grade mesothermal quartz-sulphide gold vein system. The geology of the property consists primarily of a sequence of meta-sedimentary rocks consisting of pelites, semi-pelites, and psammites. Gold occurs in quartz veins ranging in thickness from a few centimetres to over three metres (average width approximately 1.2 metres) within a west-northwest trending vein swarm.
