(collectively, the “Parties”)

WHEREAS Tournigan Gold Corporation (“Tournigan”), Tournigan USA and Sweetwater are each party to an Option Amendment and Assignment Agreement (the “OAA Agreement”) dated September 14, 2007 pursuant to which Tournigan USA agreed to pay Sweetwater US$50,000 and a further CDN$592,000 in cash, and deliver to Sweetwater an aggregate of 340,000 common shares in the capital of Tournigan to exercise the Option as contemplated by section 3.7 of the Amended Option Agreement (as such term is defined in the OAA Agreement) (the “Option”).

AND WHEREAS Sweetwater acknowledges that there are certain deficiencies in the land tenure reports prepared by Meadowlark Search, Inc. relating to certain of the Properties (as such term is defined in the OAA Agreement), particulars of which deficiencies are set out in a letter from the Sweetwater to Tournigan USA dated as of the date of the OAA Agreement (each a “Deficiency”, and collectively, the “Deficiencies”).

AND WHEREAS pursuant to the OAA Agreement, Sweetwater agrees to rectify the Deficiencies to the satisfaction of Tournigan USA within four months of the Closing (as such term is defined in the OAA Agreement), failing which Tournigan USA shall be entitled to rectify the Deficiencies and shall be entitled to reimbursement by Sweetwater for the fees and expenses it incurs in doing so.

AND WHEREAS the OAA Agreement further provides that in the event a Deficiency cannot be rectified by Sweetwater or by Tournigan USA, as the case may be, Sweetwater will pay Tournigan USA an amount equivalent to the reduction in the value of the Properties caused by the Deficiency (a “Deficiency Payment”), such amount to be agreed to by Sweetwater and Tournigan USA, acting reasonably.

- 2 -

AND WHEREAS the OAA Agreement provides, among other things that at the Closing of the exercise of the Option, an aggregate of $100,000 (the “Escrowed Cash”) will be placed into escrow, and that Tournigan USA may require the Escrow Agent to release some or all of the Escrowed Cash to Tournigan USA to be applied towards the payment of any Deficiency Payment, all on the terms and conditions of this Agreement.

AND WHEREAS Sweetwater and Tournigan USA wish to appoint the Escrow Agent to act as escrow agent in respect of the Escrowed Cash and the Escrow Agent wishes to act in such capacity, on the terms and conditions contained herein.

AND WHEREAS the Escrow Agent has agreed to undertake and perform its duties according to the terms and conditions hereof:

NOW THEREFORE this Agreement witnesseth that in consideration of the aforesaid agreements, and of the sum of $1.00 now paid by the Parties hereto, each to the other (the receipt and sufficiency of which the Parties do hereby respectively acknowledge each to the other), the Parties covenant and agree as follows:

1. At the Closing, Tournigan USA will place and deposit in escrow with the Escrow Agent the Escrowed Cash as security for losses caused to Tournigan USA by reason of Deficiencies which cannot be rectified by Sweetwater or by Tournigan USA.
    

2. The parties agree that the Escrowed Cash will be held and retained by the Escrow Agent in a separate interest-bearing trust account pursuant to the terms of this Agreement. During the term of this Agreement, ownership of and interest in the Escrowed Cash shall not be transferred, sold, assigned, alienated, released from escrow, transferred within escrow, or otherwise in any manner dealt with, except as hereafter provided. Any interest accrued in respect of the Escrowed Cash shall form part of the Escrowed Cash and be held in escrow pursuant to this Agreement.
    

3. During the term of this Agreement, Tournigan USA may deliver to the Escrow Agent a clear, irrevocable direction (a “Tournigan USA Direction”) executed by the President, Secretary or other authorized representative of Tournigan USA, providing:

1. particulars of any Deficiency which cannot be rectified, including the amount of any loss caused such Deficiency; and
    

2. particulars of the Deficiency Payment required to be made by Sweetwater to Tournigan USA in relation to such Deficiency, including the amount of such Deficiency Payment,

- 3 -

and directing the Escrow Agent to release Escrowed Funds to it to be applied toward such Deficiency Payment (the “Specified Funds”). Tournigan USA must deliver a copy of the Tournigan USA Direction to Sweetwater at the same time it delivers the Tournigan USA Direction to the Escrow Agent. Except as provided in section 4 of this Agreement, 15 Business Days (as such term is defined in the OAA Agreement) following the receipt of a Tournigan USA Direction, which the Escrow Agent shall be entitled to rely on and act upon, the Escrow Agent shall deliver the Specified Funds to Tournigan USA as directed in a Tournigan USA Direction. Tournigan USA may deliver one or more Tournigan USA Directions during the term of this Agreement.

4. If Sweetwater objects to the contents of a Tournigan USA Direction, Sweetwater must deliver to Tournigan USA and the Escrow Agent written notice of such objection (a “Sweetwater Objection Notice”) executed by the President, Secretary or other authorized representative of Sweetwater within 10 Business Days following the date on which it receives a copy of the Direction from Tournigan USA. The Sweetwater Objection Notice shall indicate the basis for Sweetwater's objection to the contents of such Tournigan USA Direction. If no Sweetwater Objection Notice is delivered to the Escrow Agent within the prescribed time period, the Escrow Agent shall deliver the Specified Funds as directed in the Tournigan USA Direction. In the event that a Sweetwater Objection Notice is delivered to the Escrow Agent within the prescribed time period, the Escrow Agent shall continue to hold the Escrowed Cash for ten Business Days, during which period Tournigan USA and Sweetwater shall make their commercially reasonable best efforts to resolve any dispute they may have as to the contents of the Tournigan USA Direction. If during this period the Escrow Agent receives a joint written direction (a “Joint Direction”) executed by the President, Secretary or other authorized signatory of each of Sweetwater and the Tournigan USA directing that the Escrow Agent disburse the Escrowed Cash in accordance with such Joint Direction or not disburse Escrowed Cash, the Escrow Agent shall proceed to disburse some or all of the Escrowed Cash in accordance with such Joint Direction, or shall not disburse such funds notwithstanding the Direction. If no Joint Direction is received by the Escrow Agent within 30 Business Days following receipt of a Sweetwater Objection Notice by the Escrow Agent, the Escrow Agent shall be entitled to deal with the Escrowed Cash solely in accordance with section 14 of this Agreement.
    

5. During the term of this Agreement, Sweetwater may deliver to the Escrow Agent a clear, irrevocable direction (a “Sweetwater Direction”) executed by the President, Secretary or other authorized representative of Sweetwater advising that all outstanding Deficiencies have been rectified, and directing the Escrow Agent to release all remaining Escrowed Funds held by it to Sweetwater (the “Release Funds”). Sweetwater must deliver a copy of the Sweetwater Direction to Tournigan USA at the same time as Sweetwater delivers the Sweetwater Direction to the Escrow Agent. Except as provided in section 6 of this Agreement, 15 Business Days following receipt of the Sweetwater Direction, which the Escrow Agent shall be entitled to rely on and act upon, the Escrow Agent shall deliver the Release Funds as directed in the Sweetwater Direction. Sweetwater may deliver only one Sweetwater Direction during the term of this Agreement.

If Tournigan USA objects to the contents of a Sweetwater Direction, Sweetwater must deliver to Tournigan USA and the Escrow Agent a Tournigan USA Objection Notice executed by the President, Secretary or other authorized representative of Tournigan USA within 10 Business Days following the date on which it receives a copy of the Sweetwater Direction from Sweetwater. The Tournigan USA Objection Notice shall indicate the basis for Tournigan USA's objection to the contents of such Sweetwater Direction. If no Tournigan USA Objection Notice is delivered to the Escrow Agent within the prescribed time period, the Escrow Agent shall deliver the Release Funds as directed in the Sweetwater Direction. In the event that a Tournigan USA Objection Notice is delivered to the Escrow Agent within the prescribed time period, the Escrow Agent shall continue to hold the Escrowed Cash for 10 Business Days, during which period Tournigan USA and Sweetwater shall make their commercially reasonable best efforts to resolve any dispute they may have as to the contents of the Sweetwater Direction. If during this period the Escrow Agent receives a Joint Direction executed by the President, Secretary or other authorized signatory of each of Sweetwater and the Tournigan USA directing that the Escrow Agent disburse the Escrowed Cash in accordance with such Joint Direction or not disburse Escrowed Cash, the Escrow Agent shall proceed to disburse some or all of the Escrowed Cash in accordance with such Joint Direction, or shall not disburse such funds notwithstanding the Direction. If no Joint Direction is received by the Escrow Agent within 30 Business Days following receipt of an Objection Notice by the Escrow Agent, the Escrow Agent shall be entitled to deal with the Escrowed Cash solely in accordance with section 16 of this Agreement.
