In order to maintain the Option in good standing, Terra Nova shall:

(a)fund the following expenditures (“Expenditures”):

i)in the amount of at least One Million Dollars (CDN$1,000,000) on or before May 31, 2005, such amount to be a firm commitment (“Committed Expenditures”)

(b)These Expenditures may be accelerated and applied to future years’ Expenditures, and accordingly at Terra Nova’s election the Option may be exercised sooner. If, in a given period in section 3(a), Terra Nova fails to incur sufficient Expenditures, Terra Nova will nevertheless be deemed to have satisfied section 3(a), if Terra Nova pays Noranda an amount which is equal to the difference between Terra Nova’s actual Expenditures and the amount set out in the applicable section relating to such given period in section 3(a).

4.Cash Calls. Noranda may submit an invoice to Terra Nova up to 60 days prior to a quarter in which approved Expenditures are to be incurred or committed, setting out the estimated Expenditures for such 3 month period. Noranda may also submit other invoices relating to reconciliations, bills, accounts or other requests for payment in respect of any Expenditures made by Noranda in accordance with this Letter Agreement. Within 30 days of receipt of such invoice, Terra Nova shall pay Noranda the invoice amount. For greater certainty, in the event Terra Nova fails to make full payment to Noranda pursuant to the section 4, the Option shall terminate in accordance with section 6(f). Noranda shall not be obligated to expend any funds not provided by Terra Nova.

5.Government Assistance. Any grant or other form of government financial assistance received by a party with respect to expenditures on the Property shall be shared by the parties, in the proportion of their respective expenditures at the time that such financial assistance applies.

6.During the Option Period:

(b)Noranda shall have the right to be operator and shall be entitled to include as Expenditures administrative and overhead charges of 10% of direct project costs;

Notwithstanding, if Terra Nova is in default of this Letter Agreement, Noranda shall not provide such information to Terra Nova until such default is corrected.
2. At any time after the Committed Expenditures are incurred, Terra Nova may terminate this Letter Agreement, allow this Letter Agreement to lapse by not fulfilling the requirements of section 3, or abandon its Option on all or part of the Property.
3. If either party acquires, directly or indirectly, any interest in any property which to the extent that property is within an area of interest as shown on a map attached hereto in Schedule B, the acquiring party must disclose it to the other party, who shall then have 30 days to elect to have the acquired property become part of the Property. The other party must then pay the acquiring party its proportionate share of the acquisition costs (which shall be deemed to be 50% during the Option Period).

Formation of the Joint Operating Company

7.If Terra Nova exercises the Option, then a joint operating company will automatically be formed between Noranda and Terra Nova (the “Joint Operating Company”). The following is a summary of the main Joint Operating Company terms:

Joint Operating Co. Interests	50%	50%	100%

(b)Each party shall contribute its percentage interest share of expenditures to the Joint Operating Company, failing which its interest shall be diluted according to the following formula:

A = B x 100%, where

C

A is a party’s Joint Operating Company interest,

B is a party’s deemed expenditures under section 7(a) above, plus all of the party’s actual expenditures made after the formation of the Joint Operating Company, and

C is the parties’ total deemed expenditures under section 7(a) plus all of the parties’ expenditures made after the formation of the Joint Operating Company

Each party shall have a vote equal to its percentage interest in the Property. In case of a tie, the operator shall have the casting vote.

(e)Noranda shall be the initial operator and shall be entitled to remain as operator as long as it is not in default, and has at least a 50% interest in the Property, in which case the non-operator may become operator as long as those conditions persist.

(f)The operator may include as expenditures an administrative and overhead charge of 15% of direct project costs, 5% of third party contract work and 3% of capital costs.

The non-operator must pay the invoice within 30 days of receipt, failing which interest shall be charged at the rate of the Canadian Imperial Bank of Commerce’s prime rate plus 10%. If the non-operator fails to make full payment, including interest, within 60 days of the expiry of the 30 day period, its joint operating company interest shall automatically be extinguished and converted to a 1% Royalty as per clause 7(c) (i) and (ii).

(i)The operator shall not take any of the following actions without the prior written unanimous consent of the management committee:

(i)create, or permit to remain, any liens on any joint asset;

12. Notwithstanding section 11, Terra Nova may not assign this Letter Agreement without the prior written consent of Noranda, not to be unreasonably withheld, provided that it may assign to an affiliated company, which must then agree to be bound by the terms of this Letter Agreement. If Terra Nova has exercised its Option to earn a 50% interest in the Joint Operating Company, thereafter Noranda may not assign this Letter Agreement without the prior written consent of Terra Nova, not to be unreasonably withheld, provided that it may assign to an affiliated company, which must then agree to be bound by the terms of this Letter Agreement.

14. Each party shall promptly execute and deliver all further documents and take all further action reasonably necessary or desirable to give effect to the terms and intent of this Letter Agreement.

15. No waiver of any term of this Letter Agreement by a party is binding unless such waiver is in writing and signed by the party entitled to grant such waiver. No failure to exercise, and no delay in exercising any right, remedy or breach under this Letter Agreement shall be deemed to be a waiver of that right, remedy or breach.

16. No amendment, supplement or restatement of any term of this Letter Agreement is binding unless it is in writing and signed by each party.

17. A standard force majeure clause shall apply to this Letter Agreement.

18. Unless otherwise specified, words importing the singular include the plural and vice versa. The term “including” means “including, without limitation.”

19. The division of this Letter Agreement into sections and the insertion of headings are for convenience of reference only and are not to affect the construction or interpretation of this Letter Agreement.

20. If any term of this Letter Agreement is or becomes illegal, invalid or unenforceable, that term shall not affect the legality, validity or enforceability of the remaining terms of this Letter Agreement.

21. This Letter Agreement constitutes the entire agreement between the parties with respect to the subject matter herein and supersedes all prior agreements, negotiations, discussions, undertakings, representations, warranties and understandings, whether written or verbal.

22. For every provision in this Letter Agreement, time is of the essence.

23. This Letter Agreement shall be governed by and shall be construed and interpreted in accordance with the laws of Ontario and the laws of Canada applicable in Ontario.

If the foregoing terms and conditions reflect our agreement, please execute and return the enclosed copy of this Letter Agreement, which is intended to create a binding agreement between us. We will then prepare a formal definitive Agreement which outlines other terms which are normal to the industry for the review and signature of both parties.

SCHEDULE D

to the Letter Agreement between Noranda Inc. and Terra Nova Gold Corp. dated May 18, 2004.

NET SMELTER RETURN ROYALTY

1.For the purposes of this Agreement the term "Net Smelter Returns" shall mean the actual proceeds received from any independent custom smelter, mill, mint or other purchaser for the sale of all minerals, metals or concentrates extracted and derived from the ore mined from the Property after deducting therefrom all charges and penalties for smelting and refining and the cost of transportation (to the mill or smelter and thereafter to the mint), insurance premiums, sampling and assaying charges incurred after the minerals, metals or concentrates have left the Property and all appropriate mint charges.

2.Within ninety (90) days following the end of each calendar year, commencing with the year in which the Property is brought into Commercial Production, the Operator shall deliver to the non-operator a statement of the Net Smelter Returns for the said calendar year, duly certified by an independent Chartered Accountant appointed by the Operator for such purposes, together with payment of the royalty, if any, determined as aforesaid. If the amount of Net Smelter Return is not ascertainable for a calendar quarter, it shall be estimated as nearly as possible at the time for payment and an adjustment shall be made at the end of each calendar year. The non-operator shall have the right within a period of three (3) months from receipt of the audited statements to conduct an independent audit at its own cost and expense, the right to review the Operator's books and records relating thereto and an opportunity to discover issues raised with the Operator's auditors.
