                                    RECITALS

         A. Lewis owns the Lewis Mine situated in Humboldt and Pershing
Counties, Nevada and more particularly described in Exhibit A attached hereto
and incorporated herein (the "Lewis Mine").

         B. The Lewis Mine is subject to a "Mining Lease" dated January 1, 1983
between Frank W. Lewis as Lessor and the Standard Slag Corp. as Lessee. The
Mining Lease has been transferred through various conveyances to the present
holders, Hycroft Lewis, Inc. and Vista Gold Corp. (collectively "Vista"). The
Mining Lease, any amendments thereto, and all conveyances affecting the Mining
Lease shall be referred to collectively as the "Vista Lease."

         C. Great American wishes to obtain the exclusive right and option to
acquire Lewis' interests under the Vista Lease, which include (but are not
limited to) the right to receive lease payments and production royalties, Lewis'
ownership interest in the Lewis

                                       -1-


Mine, Lewis' reversionary interest in the Lewis Mine, and the various
contractual obligations owed by Vista to Lewis under the Vista Lease. These
rights shall be referred to collectively as the "Leasehold Rights."

         NOW THEREFORE, the parties agree as follows:

                                   SECTION ONE
                               Option to Purchase

         1.1 Initial Option. Lewis grants to Great American the exclusive option
to undertake due diligence and other studies with respect to the Lewis Mine (the
"Initial Option"). The Initial Option shall have a term of two (2) months
commencing on June 15, 2004 and ending at midnight on August 14, 2004. During
the Initial Option, Great American shall have the right to conduct such inquires
and investigations as it deems appropriate regarding title, mineral potential,
environmental factors, and other issues affecting the Lewis Mine.

         In consideration of the Initial Option, Great American has paid Lewis
the sum of TWENTY-FIVE THOUSAND DOLLARS ($25,000.00), receipt of which is
hereby acknowledged by Lewis. This Initial Option payment shall be applied to
the purchase price in the event that Great American proceeds with this Agreement
in accordance with Section 1.2 below.

         1.2 Extended Option Period. On or before August 15, 2004, Great
American may elect to enter into an extended option (the "Extended Option") to
purchase the Leasehold Rights from Lewis. The Extended Option shall have a
period of two (2) years,

                                       -2-


commencing on August 15, 2004 (the "Effective Date") and ending at midnight on
August 14, 2006.

         During the term of the Extended Option, and until Great American
exercises its option to purchase pursuant to Section 1.3 below, Great American
shall make the following option payments to Lewis:

         a. Great America shall pay the sum of TWO HUNDRED FIFTY THOUSAND
DOLLARS ($250,000.00) to Lewis on or before August 15, 2004 to main tain the
Extended Option in effect for a period of six (6) months.

         b. Thereafter, Great American shall make option payments to Lewis in
accordance with the schedule below. Each $250,000.00 payment shall maintain
the Extended Option for the ensuing six (6) months:

                 Date of Payment                Amount of Option Payment
                 ---------------                ------------------------
               February 15, 2005                      $250,000.00
               August 15, 2005                        $250,000.00
               February 15, 2006                      $250,000.00

         All of the option payments made pursuant to Sections 1.1 and 1.2 shall
be applied to the purchase price.

         1.3 Exercise of Option. At any time on or before August 15, 2006, Great
American may exercise its option to purchase the Leasehold Rights (the "Option
to Purchase") by giving written notice to Lewis as provided in this Agreement.
The purchase price for the Leasehold Rights shall be SEVEN MILLION FIVE HUNDRED

                                       -3-


THOUSAND DOLLARS ($7,500,000.00), less the option payments made pursuant to
Sections 1.1 and 1.2 above. The Option to Purchase will be deemed to have been
exercised on the date that Great American transmits to Lewis a written notice of
exercise of the Option to Purchase. Upon receipt of such notice, Lewis and Great
American shall set a closing date, which shall in no event be later than thirty
(30) days from the receipt of such notice.

         1.4 Work Commitment. In addition to the option payments described in
Sections 1.1 and 1.2 above, Great American shall commit to undertake TWO HUNDRED
FIFTY THOUSAND DOLLARS ($250,000.00) in evaluating the Lewis Mine during each
year following the Effective Date ("Expenditures"). These Expenditures are
intended to assist Great American in evaluating the title and mineral potential
of the Lewis Mine. In the event that Great American does not fulfill its work
obligation during a contract year (i.e., each twelve-month period following the
Effective Date), it will pay the difference between its actual Expenditures and
$250,000.00 to Lewis within fifteen (15) days following the end of each contract
year. Excess Expenditures from one contract year shall be carried forward and
credited against the amount of any and all Expenditures due during the next
contract year.

         Expenditures toward the work obligation shall not include off-site
corporate costs, corporate legal fees, accounting fees, officers' salaries, or
promotional expenses of any kind. However, to the extent that corporate officers
are qualified to provide geological or mining-related services, their salaries,
pro-rated to account for time spent for benefit of

                                       -4-


 the Lewis Mine, shall qualify as Expenditures. Geological or engineering work
 done off-site for the benefit of the Lewis Mine shall also be included as
 Expenditures.

         In the event that Great American undertakes exploration drilling on the
Lewis Mine with the permission of and in coordination with Vista, Great American
shall first enter into a separate agreement with Lewis regarding assay
requirements, survey of drill holes, delivery of data, and delivery of core and
drill samples.

                                   SECTION TWO
                        Obligations during Option Period

         2.1 Right of Evaluation. Upon execution of this Agreement, Great
American shall have the right to evaluate the Lewis Mine in order to determine
whether to exercise the Option. However, such evaluation shall proceed in
accordance with (1) those rights reserved or granted to Lewis under the Vista
Lease and (2) such rights as Great American may negotiate directly with Vista.

         2.2 Environmental Evaluation. Great American has completed an
environmental evaluation of the Lewis Mine and accepts the Lewis Mine in its
current environmental condition. In the event Great American exercises its
Option, Great American shall assume all of Lewis' environmental reclamation and
clean-up liabilities which are not covered by the Vista Lease, including
environmental conditions that pre-dates the Effective Date of this Agreement.

                                       -5-


         Great American shall reclaim any disturbance, including drilling,
created by its activities under this Agreement in accordance with applicable
rules and regulations of the appropriate state and federal agencies.

         2.3 Data. Upon execution of this Agreement Lewis shall make available
for copying by Great American all maps, deeds, and other documents pertaining to
the title, boundaries, prior work, production history, and similar material
associated with the Lewis Mine which Great American requests and which are in
Lewis' possession (but subject to the warranty disclaimers of Sections 4.3 and
4.4 below). All copies shall be made at Great American's expense.

         2.4 Area of Interest. Should Great American locate any fractional
claims ("Fractional Claims") within the perimeter of the claims comprising the
Lewis Mine, the Fractional Claims shall be located in the name of Lewis, and
Lewis hereby appoints Great American as its agent to perform such claim staking.
The Fractional Claims shall become part of the Lewis Mine, subject to all terms
and conditions of this Agreement. Lewis and Great American shall execute such
additional agreements as necessary to document the addition of the Fractional
Claims to this Agreement. Further, all Fractional Claims and any claims located
by Great American or anyone under its control within two (2) miles of the
present Lewis boundary shall be located in the name of Lewis and shall be
subject to the Vista Lease.

         2.5 Conduct of Work. Great American shall perform its activities under
this Agreement in accordance with all applicable laws and regulations, including
those relating

                                       -6-


to environmental reclamation and clean-up, and in compliance with applicable
workers' compensation laws of the State of Nevada.

         2.6 Liability and Insurance. During the term of this Agreement and
after exercise of the Purchase Option, Great American shall indemnify and hold
Lewis harmless from any claims, demands, liabilities or liens arising out of
Great American's activities on the Lewis Mine, unless arising from the sole
negligence of Lewis. During the term of this Agreement, Great American shall
obtain and carry a policy of public liability insurance in the amount of at
least ONE MILLION DOLLARS ($1,000,000) for personal injury and ONE HUNDRED
THOUSAND DOLLARS ($100,000) for property damage, protecting Lewis against any
claims for injury to persons or damage to the Lewis Mine resulting from Great
American's activities under this Agreement. The insurance policy shall name
Lewis as an additional insured and evidence of such shall be delivered to Lewis
within thirty (30) days of the Effective Date of this Agreement.

         2.7 Liens. Great American shall keep the Lewis Mine free and clear from
any and all mechanics' or laborers' liens arising from labor performed on, or
material furnished to the Lewis Mine at Great American's request. However, a
lien on the Lewis Mine shall not constitute a default if Great American, in good
faith, disputes the validity of the claim, in which case the existence of the
lien shall constitute a default thirty (30) days after the validity of the lien
has been adjudicated adversely to Great American. Lewis shall record a Notice of
Non-Responsibility on behalf of Lewis in accordance with applicable law.

                                       -7-


         2.8 Assignment. Prior to exercising the Purchase Option, Great
American may license, sell, assign, sublease or joint venture ("Transfer") this
Agreement or interests therein to another party ("Transferee") only upon the
occurrence of all of the following:

         a. Payment to Lewis of ten percent (10%) of any fees or payments
received by Great American for the Transfer, except in the case of transfer to a
wholly-owned subsidiary or affiliate of Great American, as the case may be;

         b. Approval by Lewis of the mining expertise of the Transferee; and

         c. Approval by Lewis of the fiscal responsibility of the Transferee.

         Notwithstanding anything herein to the contrary, no Transfer of the
Lewis Mine shall relieve Great American of its responsibility for performance of
all obligations under this Agreement. Great American and each Transferee shall
be jointly and severally liable for the performance of all obligations hereunder
of Great American.

         In the event Lewis determines that the expertise or fiscal
responsibility of the Transferee does not meet acceptable commercial standards,
Lewis may withhold approval of the Transfer and such Transfer shall be void. It
is understood between the parties that the payment to Lewis of a portion of the
payments received by Great American for the Transfer shall not constitute a
penalty for Transfer, but shall constitute payment to Lewis for investigation of
the professional expertise and financial trustworthiness of the proposed
Transferee.

         Prior to exercise of the Purchase Option, no Transfer shall be effected
without full compliance with the provisions of this Section, including the
written consent of Lewis.

                                       -8-


         After exercise of the Purchase Option, Great American may Transfer any
and all interest in the Leasehold Rights without approval or restriction or
payment to Lewis.

         2.9 Installation of Equipment. During the term of this Agreement, Great
Ameri can may install, maintain, replace, and remove any and all machinery,
equipment, tools and facilities ("Equipment") which it places on the Lewis Mine
to use in connection with its evaluation activities under the Agreement or other
activities after exercise of the Extended Option. In the event Great American
does not exercise the Option to Purchase, upon termination of this Agreement for
any reason Great American shall have a period of thirty (30) days following such
termination during which it shall remove all of the Equipment at its sole cost
and expense.

         2.10 Acquisition of Permits. Great American shall acquire all federal,
state and local permits required for its activities under this Agreement,
including without limitation those pertaining to reclamation and the posting of
a reclamation bond, as may be required by law.

         Great American shall simultaneously deliver to Lewis copies of all
permit applications filed with regulatory agencies pertaining to the Lewis Mine
or its operations hereunder. Great American shall, promptly upon their receipt,
deliver to Lewis copies of all permits, amendments, and modifications issued for
the Lewis Mine or its operations hereunder.

         2.11 Inspection of Lewis Mine. Lewis, or its authorized agents or
representa- lives, shall be permitted to enter the Lewis Mine at all reasonable
times for the purpose

                                       -9-



of inspection, surveying and sampling, but shall enter the Lewis Mine at their
own risk and so as not to unreasonably hinder the operations of Great American.
Lewis shall give reasonable notice before any visit and shall indemnify and hold
Great American harmless from any damage, claim or demand by reason of injury to
Lewis or its agents or representatives, including death or damage to or
destruction of any property of Lewis or said agents or representative while on
the Lewis Mine or the approaches thereto.

         2.12 Taxes. Great American shall pay all taxes levied or assessed
against any improvements placed on the Lewis Mine by Great American. Lewis shall
provide promptly to Great American copies of all documents relating to such
taxes. Great American may take such action, at its expense, as it deems proper
to obtain a reduction or refund of taxes paid or payable by it, and Lewis shall
cooperate in such action, including but not limited to allowing such action to
be taken and prosecuted in Lewis' name. In the event Great American does not
exercise the Option to Purchase, upon termination of this Agreement, taxes shall
be apportioned between Lewis and Great American on a calendar year basis for the
remaining portion of the calendar year. Lewis shall not be liable for taxes on
any Equipment placed on the Lewis Mine under this Agreement.

                                  SECTION THREE
                            Default and Termination

         3.1 Termination. Subject to the other terms of this Agreement, Great
American shall have the right to terminate this Agreement at its sole discretion
at any time after paying the Option payments described in Section 1. 2(b) and by
satisfying the first year's

                                      -10-


work commitment described in Section 1.4. Upon termination Lewis shall retain
all payments previously made and this Agreement shall cease and terminate.
Within thirty (30) days after termination, Great American shall provide to Lewis
all Data developed by Great American with respect to the Lewis Mine. To the
extent practical all Data shall be provided in electronic format as well as hard
copy. Great American makes no representation or warranty, express or implied of
any kind or nature whatsoever with respect to the accuracy or reliability of the
Data. Termination by Great American shall be effective as of the date Great
American transmits to Lewis a written notice of termination and a quitclaim deed
conveying to Lewis all of Great American's right, title and interest in the
Lewis Mine and to any additional claims located pursuant to Section 2.3.

         At the time of executing this Agreement, Great American shall sign and
deliver a Quitclaim Deed to Lewis relinquishing all of Great American's right,
title, and interest in the Leasehold Rights. The Agreement shall be held in
trust by Richard W. Harris, Esq., and shall be released and recorded in the
event of termination or an unremedied default pursuant to this Section 3.

         3.2 Default. Prior to exercise of the Option to Purchase or termination
by Great American, if Great American fails to perform its obligations under this
Agreement, and in particular fails to make any payment due Lewis hereunder,
Lewis may declare Great American in default by giving Great American written
notice specifying the obligation(s) which Great American has failed to perform.
If Great American fails to remedy a default

                                      -11-


in payment within fifteen (15) days of receiving notice of such default, or has
not begun to cure any other default within thirty (30) days and thereafter
diligently prosecute such action to completion, Lewis may terminate this
Agreement and Great American shall peaceably surrender possession of the
Leasehold Rights to Lewis. However, if Great American disputes in writing that
any default has occurred, the matter shall be determined by litigation in a
court of competent jurisdiction. If Great American is found to be in default
hereunder, Great American shall have a reasonable time to cure such default, and
if so cured, Lewis shall have no right to terminate this Agreement by reason of
such default. Great American shall promptly respond in writing to any notice of
default served on Great American, either by curing the default or providing a
written explanation as to why, in Great American's opinion, a condition of
default does not exist.

         3.3 Obligations Following Termination. In the event of any termination
of this Agreement, except a termination under Section 4.6 hereof, Great American
shall surrender possession of the Leasehold Rights to Lewis. In the event of any
termination of this Agreement, Great American shall have no further liability or
obligations under this Agreement, except for any obligations: (1) to pay its
apportioned share of taxes as provided in Section 2.12 hereof, (2) to pay any
payments owed to Lewis upon the effective date of termination, (3) to remove
Equipment as provided in Section 2.8 hereof, (4) to fulfill its reclamation
obligations pursuant to Section 2.1 hereof, and (5) to satisfy any other accrued
obligations or liabilities imposed by this Agreement or by operation of law.

         4.10 Entire Agreement. This Agreement terminates and replaces all prior
agree ments, either written, oral or implied between the parties hereto, and

full force and effect and shall in no way be affected, impaired or invalidated
thereby.
