Mr. Byard MacLean, P. Eng.

British Columbia, 

Mr. MacLean:

The purpose of this letter (the “Letter of Intent”) is to outline the terms and conditions upon which Zena Capital Corp. (“Zena”) proposes to enter into an option agreement (“Option”) to acquire up to 100% of certain mineral rights in properties located in British Columbia (hereinafter referred to as “Barite”).  We acknowledge that this letter is an expression of intent only and does not result in the formation of a binding agreement between us other than in respect of Paragraphs 1, 2, and 6.4, which will be binding obligations on the parties in accordance with their terms.

1.

Exclusivity / Closing

1.1

It is acknowledged that Zena has incurred and will incur significant expenses in completing its due diligence in preparation for the closing of the transactions contemplated in this Letter of Intent (“the Transaction”).  Accordingly, Byard MacLean (the “MacLean”) agrees not to initiate contact with, solicit or enter into negotiations with any other party regarding the sale or option of Barite from the date of the execution of this Letter of Intent except in the event that a formal option agreement as contemplated in Section 7.1 (i) of this Letter of Intent is not entered into within 120 days of this Letter of Intent, or in the event that the Transaction herein fails to close by October 31, 2003, in which case such prohibition will end.

It is acknowledged that MacLean has incurred and will incur significant expenses in completing his due diligence in preparation for the closing of the Transaction contemplated in this Letter of Intent. Accordingly, Zena agrees not to initiate contact with, solicit or enter into negotiations with any other party regarding the completion of a Qualifying Transaction, as defined in the policies of the TSX Venture Exchange (“Exchange”) from the date of the execution of this Letter of Intent except in the event that a formal option agreement as contemplated in Section 7.1 (i) of this Letter of Intent is not entered into within 120 days of this Letter of Intent, or in the event that the Transaction herein fails to close by October 31, 2003, or in the event Zena gives notice to MacLean that Zena does not propose to proceed with the Transaction based upon the results of the Phase 1 program of exploration to be undertaken by Zena in respect of the Barite, in which case such prohibition will end.

1.2

The closing date ("Closing Date") for the formal option agreement shall occur as soon as reasonably possible after the receipt of all necessary regulatory and shareholder approvals, provided that such Closing Date shall occur on or before October 31, 2003, otherwise this Letter of Intent and the formal option agreement contemplated herein shall terminate unless extended by mutual agreement. 

2.

Confidentiality

2.1

Zena agrees to keep confidential all those things, which may be described as trade secrets relating to Barite and the business plan that has been prepared to advance the development of Barite unless otherwise required by the law or the policies of the Exchange to make such information public. 

2.2

MacLean acknowledges that Zena is a public company with statutory disclosure requirements and, accordingly, Zena will be required to make disclosure from time to time in accordance with applicable securities legislation.  Roy Brown and MacLean will submit all necessary information as requested by Zena in respect of the Barite and the Transaction in order to enable Zena to prepare any required news release and regulatory filings.

3.

Terms of Option

3.1

MacLean represents to Zena that MacLean has all legal and beneficial title to Barite (the “Right”) subject only to certain property payments and royalty payments on production (being a minimum yearly advance royalty payment of $4,000, commencing July 21, 2003, to a maximum of $300,000 and the payment of $5.00 per tonne of barite are sold from the high grade Phase 2 target area all as disclosed in Appendix A).  MacLean represents and warrants to Zena that the Right is not subject to any other requirement, liens, encumbrances or charges.  MacLean will grant to Zena the exclusive right and option (the “Option”) to acquire up to a 100% undivided right, title and interest in and to Barite subject only to Zena continuing to make such its pro rata portion (based upon the working interest Zena has earned in the Right from time to time) of the foregoing advance royalty payments, high grade ore payments as well as those additional royalty payments to MacLean, as set out in section 3.2(iii) hereof.

3.2

The Option will be based on a three phase program of exploration and “earn-in” by Zena.  In order to exercise the Option and maintain such in good standing and in full force and effect, Zena shall:

(i)

Incur up to $40,000 on a Phase 1 program of exploration described in Appendix B (of which $10,000 will be on account of an option payment to Bill Inverarity as set out in the December 26, 2002 agreement between Bill Inverarity and MacLean listed in Appendix A) which will earn Zena an undivided 30% working interest in MacLean’s Right.  The $40,000 is to be spent by Zena prior to Exchange approval to the transaction and is to be funded as to $25,000 as permitted by section 8.5(b) of Policy 2.4 of the Exchange and as to $15,000 as part of Zena’s due diligence expenditures to be incurred on Barite.  The Phase 1 program is to be commenced within fifteen days of signing this Letter of Intent.

(ii)

Subject to the completion of Phase 1, Zena shall have the option to expend up to a further $200,000 on a Phase 2 program on Barite consisting of exploration, development and equipment purchases as set out in Appendix B (of which $25,000 will be on account of an equipment purchase payment to Bill Inverarity as set out in the December 26, 2002 agreement between Bill Inverarity and MacLean listed in Appendix A) which will earn Zena a further undivided 20% working interest in the Right thereby bringing the total interest held by Zena to an undivided 50% in the Right.  Zena will be entitled to at least a 100% payback of its expenditures from net profits derived from exploration and development of Barite on completion of Phases 1 and 2 while still maintaining its 50% interest.  Phase 2 of exploration shall be based upon a qualified engineering report (recommending the expenditure of $200,000) and will be subject to Exchange approval.  Such report must be received within one month of completing Phase 1.  Completion of Phase 1 includes Zena’s receipt of Phase 1 data necessary to complete the report.

(iii)

Subject to the completion of Phase 2, Zena shall have the option to expend a further $550,000 on a Phase 3 program of exploration, development and property royalty payment as set out in Appendix B which will earn Zena a further undivided 50% working interest in the Right subject to a 20% Net Profits Royalty (as defined in Appendix C) payable to MacLean after Zena achieves a payback of all of its expenditures on Barite (totaling $790,000 after Phase 3).  The Phase 3 program shall be based upon a qualifying engineering report recommending the expenditure of up to $460,000.  Zena must elect to fund Phase 3 within 1 month of receiving a qualified engineering report recommending the expenditure of up to $460,000 (which excludes any property royalty payment). Such report must be received within one month of completing Phase 2.  Completion of Phase 2 includes Zena’s receipt of Phase 2 data necessary to complete the report.

3.3

The formal option agreement and Zena’s interest in the Right will be held by a wholly owned subsidiary of Zena to be established in conjunction with closing of the Transaction.

3.4

Zena and MacLean will set up a committee to approve the payment of budgets in respect of Phase 1, 2 and 3.  Zena and MacLean will each have one representative appointed to this committee.  Zena will make payments on presentation of invoices as approved by such committee on a semi-monthly basis.  These expenditures will be consistent with the Phase 1, 2 and 3 budgets as attached in Appendix B.

3.5

After completing the expenditures required by Phase 1, should Zena decide not to complete the expenditures for Phase 2 or 3, then Zena’s interest will be converted to a carried Net Profits Royalty and subject to dilution. Dilution to Zena’s Net Profits Royalty if only Phase 1 is completed will take place in stages as follows based upon additional expenditures on Barite by MacLean since entering into this Letter of Intent with Zena (provided such additional expenditures by MacLean are consistent with the budgets presented to Zena as contained in Appendix B):

(i)

should MacLean spend an additional $40,000 on Barite then Zena’s carried interest will reduce to 15%;

(ii)

should MacLean spend an additional $100,000 on Barite then Zena’s carried interest will reduce to 7.5%;

(iii)

should MacLean spend an additional $200,000 on Barite then Zena’s carried interest will reduce to 5%; and

(iv)

should MacLean spend an additional $350,000 on Barite then Zena’s carried interest will reduce to 2.5%.

The foregoing dilution will take place only upon each expenditure milestone being met in full by MacLean.  After completing Phase 1 in no event can Zena’s carried Net Profits Royalty in Barite be reduced below 2.5%.  After completing the expenditures required by Phase 2 should Zena decide not to complete the expenditures required by Phase 3 then Zena’s interest will be converted to a carried Net Profits Royalty and will be subject to dilution.  Dilution to Zena’s Net Profits Royalty if Phase 2 is completed by Zena will be calculated by dividing Zena’s expenditures on Barite to the end of Phase 2 by the total expenditures on Barite since MacLean entered into the Letter of Intent with Zena (provided such additional expenditures by MacLean are consistent with the budgets presented to Zena as contained in Appendix B) and multiplying by Zena’s then held interest (being a carried 50% Net Profits Royalty) provided that if Zena completes Phase 2 then in no event can its carried Net Profits Royalty be diluted to less than 10%.

For clarification purposes only in respect of Zena having completed Phase 2:

Upon completion of Phase 2 Zena will have spent $240,000 and the dilution is calculated on the basis of $240,000/($240,000 plus MacLean’s subsequent total expenditures) times 50%.  Any total expenditure by MacLean subsequent to Zena’s election not to proceed past Phase 2 in excess of $960,000 will not dilute the Net Profits Royalty of Zena below 10%.

If Zena holds these minimum Net Profits Royalties, then these Net Profits Royalties can be purchased by MacLean for $40,000 for the Phase 1 Net Profits Royalty (2.5%) and $240,000 for the Phase 2 Net Profits Royalty (10%).  These payments to purchase the Net Profits Royalty are exclusive of proceeds received by Zena from Phase 1, 2 or 3 exploration, bulk sampling or production work.

3.6

Any net proceeds derived from Barite (after underlying royalty payments are made) as a result of the Phases 1 and 2 program, will firstly be paid to Zena, up to the aggregate amount of funds expended by Zena on Barite to that point in time.  The balance of any net proceeds derived therefrom will be used to fund the Phase 3 program plus the property royalty payment of $90,000 as expressed in Appendix B, up to a maximum of $550,000, unless Zena elects not to proceed with Phase 3.  If Zena elects not to proceed with Phase 3, then the balance of funds, after repaying Zena the aggregate amount of funds expended by Zena on Phases 1 and 2 (up to $240,000) will be paid 50% to Zena and 50% to MacLean.  If Zena elects to proceed with Phase 3, then balance of the funds derived from Phases 1 and 2, after repaying Zena the funds expended on Phases 1 and 2 (up to $240,000) will be used to fund Phase 3 plus the property royalty payment of $90,000 as expressed as Appendix B (up to $550,000).  If there remains excess funds derived from Phases 1 and 2 after repaying Zena up to the $550,000 Zena expended on Phase 3 and for the property royalty payment, then 40% of the excess funds derived from Phases 1 and 2 will be paid to Zena and 60% of the excess funds will be paid to MacLean.

3.7

Zena will pay MacLean a 20% Net Profits Royalty on any net profits derived from Phase 3 and net profits derived after Phase 3.  Zena or its nominee may purchase the Net Profits Royalty after completion of Phase 2 and before Phase 3 is commenced for $400,000.  Should Zena elect to purchase the 20% Net Profits Royalty, Zena will have 360 days from the date of election to fund such purchase.  Any time after Phase 3 is commenced, the Net Profits Royalty may be purchased by Zena for the lower of 20% of the net present value of Barite (as determined by an independent valuator) and 20% of a 3rd party arms length offer to purchase Barite provided that the 3rd party arm’s length offer to purchase is not less than 80% of the net present value.

4.

Management / Consulting Agreements

4.1

It is acknowledged that the services of MacLean are essential to the success of the Barite and Zena is desirous of appointing MacLean as the Operator of the Project and accordingly, he agrees to enter into an agreement with Zena upon the commencement of Phase 2, the terms of which are to be mutually agreed upon.  Subject to applicable regulatory approval MacLean will be paid a retainer of $1,000 per month plus a $250 per diem for each day of attendance at the property, within the framework of the Budget (see Appendix B) for Phases 2 and 3.

4.2

The parties hereto agree that Roy Brown will, upon commencement of Phase 1, be retained to provide consulting services with respect to due diligence, and other administrative requirements to facilitate the closing of the Transaction.  Zena will pay a retainer of $2,500 per month for two months, at which time Zena will review this payment and determine whether the need for Mr. Brown’s further services are required.  If his further services are deemed required, the parties agree to retain Mr. Brown for an additional period of up to ten months at a retainer of $2,500 per month.  The payment will be made on the 15th day of each month and may be pro rated in the first month.

4.3

Stock options will be granted to Roy Brown and MacLean on closing in conjunction with the negotiation of agreements contemplated in Sections 4.1 and 4.2. The terms of the stock option grants will be negotiated in good faith within the guidelines and limitations of Exchange policy. These options will be earned and vested as to 50% on completion of Phase 2 and 50% on completion of Phase 3, in addition to any vesting provisions required by the Exchange.

5.

Financing / Sponsorship

5.1

Zena will select and retain a sponsor for the proposed transaction as required by the Exchange.

5.2

Zena and MacLean will collectively use their best efforts to complete a public or private equity financing of approximately $250,000, the final amount and pricing of the financing to be subject to Exchange approval, in conjunction with closing the transaction.

6.
