Attention:

Mr. William  Wolfe

Dear Sirs:

RE:

PURCHASE OF ULSTER MINERALS LIMITED (“Ulster”)

We have jointly entered into option agreements respecting the Curraghinalt and Tyrone properties dated February 3, 2003 respectively (the “Option Agreements”).   We understand that the “Mineral Rights” on the “Properties” (both as defined in the Option Agreements, which definition shall apply here) are held by your wholly owned subsidiary, Ulster.  As we have discussed, it is our desire to move aggressively towards production from the Properties, and to that end we wish to acquire a 100% interest in the properties through the acquisition of 100% of Ulster.

We are writing this letter (“Agreement”) to confirm the terms for the purchase and sale of all of the issued and outstanding shares of Ulster (the “Ulster Sale”) by its sole shareholder, Strongbow Resources Ltd (“Strongbow”), to Tournigan Gold Corporation (“Tournigan”) subject to obtaining all necessary shareholder and regulatory approvals (including all necessary acceptances of The TSX Venture Exchange (“TSX”)), upon the terms and conditions set out below.

Purchase and Sale Agreement

1.

Strongbow hereby agrees to sell all of its right title and interest in the issued shares of Ulster (“Ulster Shares”) to Tournigan at the Closing (defined below) on the terms set out herein.  .

Purchase Price

2.

The Purchase Price for the Ulster Shares shall be:

(a)

10,000,000 common shares of Tournigan, issued at a deemed price of $0.♦ per share (the “Purchase Shares”); and

(b)

Tournigan's covenant to pay to Strongbow, whenever Ulster applies the cumulative exploration expenditures disclosed on the books of Ulster as at the date of closing against its income, an amount (the "SR Share of Tax Credit") equal to $0.20 for every $1.00 by which Ulster's taxes payable are reduced as a consequence of the deduction of such expenditures within 30 days of the date that Ulster claims such expenditures as a deduction.  For this purpose the amount by which Ulster's taxes payable are reduced as a consequence of the deduction of exploration expenditures shall be calculated as though the deductions are against income that would otherwise be taxed at the highest marginal tax rate that would have been applicable to Ulster in respect of the value of its operating income in the relevant year less interest charges relating to mining operations on the Properties in such year but before any other deductions (i.e. after deducting interest, the existing exploration expenditures will be considered to be the first deductions in any year against income of Ulster).

The Purchase Shares shall be issued as follows:  

(c)

5,000,000 Purchase Shares shall be issued forthwith upon the issuance by the TSX of a bulletin accepting this agreement for filing; and

(d)

the remaining 5,000,000 Purchase Shares (the “5m Balance”) will be issued upon the decision by Ulster or Tournigan (whichever occurs first and whether it is a formal board decision or a de facto management decision) to commence construction of commercial scale mining facilities on the Properties;

Additional Terms

3.

(a)

Strongbow shall be entitled to name one representative for appointment to the Board of directors of Tournigan to be appointed at the closing of this transaction.  Strongbow shall continue to have a right but not the obligation, to a representative on Tournigan’s board for so long as Strongbow retains not less than 50% of the Tournigan shares it has been issued. The right is exercisable by submitting one nominee each year for inclusion in the annual materials as a management nominee for the board of directors of Tournigan.

(b)

Upon Closing the Option Agreements will be terminated, and replaced in whole by this agreement..

(c)

The number of Tournigan shares or other securities to be issued in respect of Tournigan's obligation to issue the 5m Balance shall be adjusted in accordance with industry standard comprehensive anti-dilution provisions in the event of alterations in the share capital of Tournigan or other significant transactions including share splits or consolidations, capital reorganizations or reclassifications, discounted (greater than the maximum discount in respect of private placements permitted at the time under TSX Venture Exchange Policies) rights offerings, amalgamations, mergers, arrangements and stock dividends and other such events.

(d)

Strongbow has agreed to accept the payment of the 5m Balance and the SR Share of Tax Credit at a future date on the assumption that Tournigan will hold 100% of the outstanding shares of Ulster and a 100% interest in the Properties at the time those payments are due.  Accordingly, Tournigan agrees that it will not sell, assign or transfer, directly or indirectly, any shares of Ulster, allow Ulster to sell, assign or transfer any interest in the Properties or allow Ulster to issue shares to anyone other than Tournigan until all such payments have been made unless, at the time of such transaction, Strongbow receives such consideration and other contractual entitlements satisfactory to it in respect of such rights.

The completion of the Sale of Ulster Shares (the “Closing”) will be at the offices of Armstrong Simpson 2080 – 777 Hornby Street, Vancouver, British Columbia, at 10:00 a.m. (Vancouver time) on the 2nd business day after receipt of all necessary regulatory approvals (the “Closing Date”), or such other place or date as may be mutually agreed by the parties.
