                                 LEASE AGREEMENT

Steve Sutherland (Lessor) agrees to lease to Prelude Ventures, Inc. (Lessee) the

14, 23, 24, 25, and 26, T28N, R60E, MDB&M in Elko County, Nevada (referred to as
property), subject to the following conditions:

RECITALS:

B.   "Lease Year" means each one (1) year period following the Effective Date
     and each anniversary of the Effective Date.

C.   WARRANTIES. The Lessor warrants that he is the owner of the lode mining
     claims more particularly described in Exhibit A and said claims are free
     from all liens and encumbrances.

D.   EXPLORATION AND DEVELOPMENT RIGHTS. Lessor will grant the Property to
     Lessee for the Lease period with the exclusive right to explore, develop,
     and mine the Property for gold, silver, and other valuable minerals.

E.   PERFORMANCE REQUIREMENTS / ASSUMPTION OF CLAIM MAINTENANCE. Under
     applicable Federal, State and County laws and regulations, Federal,
     State, and County annual mining claim maintenance or rental fees are
     required to be paid for the unpatented mining claims which constitute all
     or part of the Property, beginning with the annual assessment work period
     of September 1, 2001 to September 1, 2002. Prelude shall timely and
     properly pay the Federal, State, and County annual mining claim
     maintenance or rental fees, and shall execute and record or file, as
     applicable, proof of payment of the Federal, State, and County annual
     mining maintenance or rental fees and of Lessor's intention to hold the
     unpatented mining claims which constitute the Property. If Prelude does
     not terminate this Lease before June 1 or any subsequent Lease Year,
     Prelude will be obligated either to pay the Federal, State, and Local
     annual mining claim maintenance or rental fees for the Property due that
     year or to reimburse Lessor for same.

F.   AREA OF INTEREST. Any additional claims located or acquired by the Lessee
     within one (1) mile from the exterior boundaries of the mining claims
     described in Exhibit "A" shall become a part of the leased property and
     shall be subject to the terms of this lease as of the Effective Date.

G.   SCHEDULE OF MINIMUM PAYMENTS. The Lessee shall pay to the Lessor minimum
     payments, which shall be advance payments of the Royalty, of US$5000.00

<PAGE>

     (five thousand dollars) upon execution of this lease. The Lessee may
     extend this lease upon payment of the following:

       1.     Pay Lessor US$7,500.00 on or before the first anniversary of the
              execution of this lease.

       2.     Pay Lessor US$10,000.00 on or before the second anniversary of the
              execution of this lease.

       3.     Pay Lessor US$20,000.00 on or before the third anniversary of the
              execution of this lease.

       4.     Pay Lessor US$50,000.00 on or before the fourth anniversary of the
              execution of this lease.

       5.     Each annual payment thereafter shall be US$50,000.00 plus an
              annual increase or decrease equivalent to the rate of inflation
              designated by the Consumer's Price Index (CPI) for that year with
              execution year as base year. Each such payment shall be made on or
              before the successive anniversary of the execution of this lease.

H.   BUYOUT. Buyout price is US$5,000,000 (five million dollars) from which
     advance royalty payments, made up to the day of the buyout, may be
     subtracted from the Buyout price. Lessee will pay Lessor a perpetual
     one-half per cent (0.5%) royalty on Net Smelter Returns (as defined below
     in Section I. of this document) thereafter.

I.   DEFINITION OF NET SMELTER RETURNS. During the term of this Agreement,
     Lessee shall pay to Lessor, as a land owner's Production Royalty, a
     percentage of the Net Smelter Returns (as defined below) from the sale of
     any Valuable Minerals, Ore, and Product mined and sold from the Property.
     "Net Smelter Returns" are defined as the gross revenues actually received
     by the Lessee from the sales of any Valuable Minerals extracted and
     produced from the Property less the following charges:

      1.     All costs to Lessee of weighing, sampling, determining moisture
             content and packaging such material and of loading and
             transporting it to the point of sale, including insurance and
             in-transit security costs.

      2.     All smelter costs and all charges and penalties imposed by the
             smelter, refinery, or purchaser.

      3.     Marketing costs and commissions.

      4.     Not withstanding the foregoing, for purposes of determining the
             royalty payable to Lessor on any gold and/or silver produced from
             the Property, the price attributed to such gold and/or silver
             shall be the price per ounce

                                       2
<PAGE>

             of gold and/or silver on which the royalty is to be paid (as the
             case may be) as quoted on the London Metals Exchange at the PM
             fix on the day prior to the date of final settlement from the
             smelter, refinery or other buyer of the gold and/or silver on
             which the royalty is to be paid (the "Quoted Price"). For
             purposes of determining the gross revenues, in the event the
             Lessee elects not to sell any portion of the gold and/or silver
             mined from the Property, but instead elects to have the final
             product of any such gold and/or silver credited to be held for
             its account with any smelter, refiner, or broker, such gold
             and/or silver shall be deemed to have been sold at the Quoted
             Price on the day such gold and/or silver is actually credited to
             or placed in Lessee's account. The percentage for this
             Production Royalty shall be three per cent (3%).

      5.     Lessor shall be paid the Production Royalty quarterly by certified
             check by the Lessee.

J.   CONDITIONS OF TERMINATION BY LESSOR. This Lease may be terminated at any
     time by the Lessor subject to the following:

             1.     If Lessee fails to meet the above lease payments, Lessor
                    must give written notice to Lessee of such default. After
                    receipt of default, Lessee has 15 days to cure the default.

             2.     If Lessee fails to make Federal, State, and County
                    maintenance payments or filing fees at least 15 days prior
                    to due date, Lessee shall notify Lessor of a possible
                    default. After 10 days, if the default is not cured Lessor
                    may initiate payment on the claims. Lessee will be able to
                    cure this default by reimbursing all Federal, State, and
                    County Payments made by the Lessor plus a 20% penalty within
                    30 days.

K.   CONDITIONS OF TERMINATION BY LESSEE. This Lease may be terminated at any
     time by the Lessee subject to the following:

                 1.     Lessee must give written notice 30 days prior to
                        relinquishing the leased property.

                 2.     In the event Lessee desires to terminate the agreement
                        after June 1 of any year, Lessee shall be responsible
                        for all Federal, State, and County maintenance and
                        filing fees for the next assessment year regarding the
                        leased property.

                 3.     Lessee shall deliver to Lessor, in reproducible form,
                        all data generated or obtained for the leased property,
                        whether factual or interpretive as defined in section P.

<PAGE>

                 4.     Lessee shall quitclaim to Lessors all claims located or
                        acquired by Lessee within one (1) mile area of interest
                        described in section F.

L.   RECLAMATION, COMPLIANCE WITH THE LAW. All exploration and development
     work performed by the Lessee during the term of this Agreement shall
     conform with the applicable laws and regulations of the state in which
     the Property is situated and of the United States of America. Lessee
     shall be fully responsible for compliance with all applicable Federal,
     State, and local reclamation statutes, regulations, and ordinances
     relating to such work, at Lessee's cost, and Lessee shall indemnify and
     hold harmless Lessor from any and all claims, assessments, fines, and
     actions arising from Lessee's failure to perform the foregoing
     obligations. Lessee's reclamation obligation shall survive termination of
     the Agreement. Lessor agrees to cooperate with Lessee in Lessee's
     application for governmental licenses, permits, and approvals, the costs
     of which shall be borne by Lessee. Lessee shall own all governmental
     licenses, permits, and approvals.

M.   LIENS. Lessee shall keep the property free from any and all liens and
     encumbrances.

N.   TRANSFER, ASSIGNMENT, RIGHT OF FIRST REFUSAL. Either party shall be free
     to assign its rights under the detailed agreement to an affiliate
     company. They also shall have the right to transfer all or part of their
     interest in the Agreement to a third party, but transfers to a third
     party shall be subject to a right of first refusal by the Lessor.
     Assignments permitted under this paragraph shall not be effective unless
     and until the permitted assignee agrees in writing in form and substance
     acceptable to the remaining party assuming all of the assigning party's
     obligations under this Lease Agreement. The party assigning interest in
     this lease shall notify the other party within 15 days of such assignment
     and all parts of this agreement will remain in effect.

     termination of the detailed agreement, Lessee shall return to Lessor all
     information of a nature similar to that described above and developed by
     Lessee during the term of the Mining Lease. If requested by Lessor not
     more than once in any 12 calendar months, Lessee shall submit to Lessor,
     within 60 days of Lessee's receipt of such request, an annual progress
     report describing Lessee's work upon the Property, the results of such
     work, and the amounts expended by Lessee in furtherance thereof to the
     date of such report.
