      THIS CREDIT AGREEMENT, dated as of February 20, 1997 between HYCROFT
RESOURCES & DEVELOPMENT, INC., a Nevada corporation (the "Borrower"), and THE
BANK OF NOVA SCOTIA (the "Lender"),


                              W I T N E S S E T H:

      WHEREAS, the Borrower is engaged directly and through Hycroft Lewis Mine,
Inc., its wholly-owned Subsidiary (such capitalized terms, and other terms used
in these recitals, to have the meanings set forth in Section 1.1 below) in the
business of exploring for and mining gold and silver in the State of Nevada;
and

      WHEREAS, the Borrower desires to obtain a Commitment from the Lender
pursuant to which U.S. Loans and Canadian Loans, in a maximum aggregate
principal amount at any one time outstanding not to exceed U.S.$13,000,000 (or
the U.S. Dollar Equivalent thereof), will be made to the Borrower from time to
time prior to the Commitment Termination Date; and

      WHEREAS, the Lender is willing, on the terms and subject to the conditions
hereinafter set forth (including Article V), to extend such Commitment and make
such Loans to the Borrower; and

      WHEREAS, the proceeds of such Credit Extensions will be used

           (a)  to make payment in full, concurrently with the initial
      Borrowing hereunder, of the Indebtedness (including a portion of the
      intercompany Indebtedness owing by the Borrower to the Parent) identified
      in Item 7.2.2(b) ("Indebtedness to be Paid") of the Disclosure Schedule;
      and

           (b)  for general corporate purposes and working capital purposes of
      the Borrower and its Subsidiary Guarantors;
                
      NOW, THEREFORE, the parties hereto agree as follows:


                                  ARTICLE I

                      DEFINITIONS AND ACCOUNTING TERMS

      SECTION I.1.  Defined Terms.  The following terms (whether or not
underscored) when used in this Agreement, including its preamble and recitals,
shall, except where the context otherwise requires, have the following meanings
(such meanings to be equally applicable to the singular and plural forms
thereof):         

      "Affiliate" of any Person means any other Person which,



   8

directly or indirectly, controls, is controlled by or is under common control
with such Person (excluding any trustee under, or any committee with
responsibility for administering, any Plan).  With respect to the Lender, a
Person shall be deemed to be "controlled by" another Person if such other
Person possesses, directly or indirectly, power to vote 51% or more of the
securities (on a fully diluted basis) having ordinary voting power for the
election of directors or managing general partners.  With respect to all other
Persons, a Person shall be deemed to be "controlled by" another Person if such
other Person possesses, directly or indirectly, power

           (a)  to vote 10% or more of the securities (on a fully diluted
      basis) having ordinary voting power for the election of directors or
      managing general partners; or

           (b)  to direct or cause the direction of the management and policies
      of such Person whether by contract or otherwise.

      "Agreement" means, on any date, this Credit Agreement as originally in
effect on the Effective Date and as thereafter from time to time amended,
supplemented, amended and restated, or otherwise modified and in effect on such
date.

      "Alternate Base Rate" means, on any date and with respect to all Base Rate
Loans, a fluctuating rate of interest per annum (rounded upward, if necessary,
to the next highest 1/16 of 1%) equal to the higher of

           (a)  the rate of interest most recently established by the Lender at
      its Domestic Office as its base rate for Loans denominated in U.S.
      Dollars; and

           (b)  the Federal Funds Rate most recently determined by the Lender
      plus 1/2 of 1%.

The Alternate Base Rate is not necessarily intended to be the lowest rate of
interest determined by the Lender in connection with extensions of credit.
Changes in the rate of interest on that portion of any Loans maintained as Base
Rate Loans will take effect simultaneously with each change in the Alternate
Base Rate.  The Lender will give notice promptly to the Borrower of changes in
the Alternate Base Rate.

      "Authorized Officer" means, relative to the Borrower and any other
Obligor, those of its officers or managing members (in the case of a limited
liability company) whose signatures and incumbency shall have been certified to
the Lender pursuant to Section 5.1.1.

      "Base Rate Loan" means a Loan denominated in U.S. Dollars bearing interest
at a fluctuating rate determined by reference to

                                     -2-


   9

the Alternate Base Rate.

      "Borrower" is defined in the preamble.

      "Borrower Pledge Agreement" means the Pledge Agreement executed and
delivered by the Borrower pursuant to Section 5.1.5 in substantially the form
of Exhibit G-1 hereto, as amended, supplemented, amended and restated or
otherwise modified.

      "Borrower Security Agreement" means the Security Agreement executed and
delivered by the Borrower pursuant to Section 5.1.6 and attached hereto as
Exhibit H-1, as amended, supplemented, amended and restated or otherwise
modified.

      "Borrowing" means the Loans of the same type, denominated in the same
Currency and, in the case of LIBO Rate Loans, having the same Interest Period
made by the Lender on the same Business Day and pursuant to the same Borrowing
Request in accordance with Section 2.4.

      "Borrowing Base Amount" means, at any time, an amount equal to 80% of the
aggregate amount of Eligible Inventory.

      "Borrowing Base Certificate" means a certificate duly completed and
executed by the chief accounting or financial Authorized Officer of the

evidenced by a Note payable to the order of the Lender, in a minimum stated
principal amount denominated in U.S. Dollars equal to the original Commitment
Amount.  The Borrower hereby irrevocably authorizes the Lender to make (or
cause to be made) appropriate notations on the grid attached to the Lender's
Note (or on any continuation of any such grid), which notations, if made, shall
evidence, inter alia, the date of, the outstanding principal of, and the
interest rate and Interest Period applicable to the Loans evidenced thereby,
and whether such Loans are denominated in U.S. Dollars or Canadian Dollars. 
Such notations shall be conclusive and binding on the Borrower and the Lender
absent manifest error; provided, however, that the failure of the Lender to
make any such notations shall not limit or otherwise affect any Obligations of
the Borrower or any other Obligor.
                            
      SECTION II.8.  Renewal of the Commitment. Any term or provision of Article
II to the contrary notwithstanding, the Borrower and the Lender hereby agree
that:   

           (a)  At least fifteen but not more than sixteen months before the
      Stated Maturity Date then in effect (if the Commitment then remains in
      effect), the Borrower may, by delivery of a written request to the
      Lender, request that the Lender provide a new commitment to extend the
      then effective Stated Maturity Date for a period of exactly one
      additional year and establish a new "Stated Maturity Date" which shall be
      extended to the date which is one year from the "Stated Maturity Date"
      then in effect at the time of delivery of such written request; provided,
      however, that the Borrower may not request more than two such extensions.

           (b)  Upon its receipt of such notification from the Borrower, the
      Lender may, in its sole and absolute discretion, agree to provide to the
      Borrower the extension described in the foregoing clause (a) (and thereby
      establish 


                                    -25-


   32


      a new Stated Maturity Date which newly established date shall
      be the date which is exactly one year from the "Stated Maturity Date"
      then in effect at the time of delivery of such notification), and the
      Lender will, no later than 30 days prior to the date which is exactly one
      year prior to the "Stated Maturity Date" then in effect at the time of
      delivery of such notification, notify the Borrower of its
      approval or disapproval of such request.


                                 ARTICLE III

                 REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

      SECTION III.1.  Repayments and Prepayments.  The Borrower shall repay in
full the unpaid principal amount of each Loan upon the Stated Maturity Date
therefor.  Prior thereto, the Borrower
                                               
            (a) may, from time to time on any Business Day, make a voluntary
      prepayment, in whole or in part, of the outstanding principal amount of
      any Loans; provided, however, that

                 (i)  no such prepayment of any LIBO Rate Loan may be made on
            any day other than the last day of the Interest Period for such
            Loan,

                 (ii)  all such voluntary prepayments shall require at least
            three but no more than five Business Days' prior written notice to
            the Lender, and

                 (iii)  all such voluntary partial prepayments shall be in an
            aggregate minimum amount equal to the U.S. Dollar Equivalent of
            U.S.$500,000 and an integral multiple equal to the U.S. Dollar
            Equivalent of U.S.$100,000;

            (b) shall, on each date when any reduction in the Commitment Amount
      shall become effective pursuant to Section 2.3, make a mandatory
      prepayment of all Loans equal to the excess, if any, of the aggregate,
      outstanding principal amount of all Loans over the lesser of (i) the
      Commitment Amount as so reduced and (ii) the then existing Borrowing Base
      Amount;

            (c)  shall, upon three Business Days' written notice from the
      Lender, in the event that the Lender shall have determined at any time
      (including on each date of the making of any Credit Extension and on the
      date of a Continuation/Conversion Notice with respect to any Credit
      Extension or at any other time periodically) that the aggregate principal
      amount of all Credit Extensions


                                    -26-


   33


      outstanding (after converting all Credit Extensions denominated in
      Canadian Dollars to their U.S. Dollar Equivalent on such date of
      determination) was in excess of the lesser of

                 (i)  the Commitment Amount that was then in effect, and

                 (ii)  the Borrowing Base Amount that was then in effect,

      make a mandatory prepayment such that the U.S. Dollar Equivalent of the
      outstanding principal amount of all Credit Extensions does not exceed the
      lesser of (x) the Commitment Amount then in effect or (y) the Borrowing
      Base Amount then in effect; and

           (d) shall, immediately upon any acceleration of the Stated Maturity
      Date of any Loans pursuant to Section 8.2 or Section 8.3, repay all
      Loans, unless, pursuant to Section 8.3, only a portion of all Loans is so
      accelerated.

Each prepayment of any Loans made pursuant to this Section shall be without
premium or penalty, except as may be required by Section 4.4.  No voluntary
prepayment of principal of any Loans shall cause a reduction in the Commitment
Amount.

      SECTION III.2.  Interest Provisions. Interest on the outstanding principal
amount of all Loans shall accrue and be payable in accordance with this Section
3.2.
                                          
      SECTION III.2.1.  Rates. Pursuant to an appropriately delivered Borrowing
Request or Continuation/Conversion Notice, the Borrower may elect that Loans
comprising a Borrowing accrue interest at a rate per annum:
                              
           (a) on that portion of U.S. Loans maintained from time to time as a
      Base Rate Loan, equal to the sum of the Alternate Base Rate from time to
      time in effect plus a margin of 1%; and

           (b) on that portion of Loans maintained as a LIBO Rate Loan, during
      each Interest Period applicable thereto, equal to the sum of the LIBO
      Rate (Reserve Adjusted) applicable to the relevant Currency for such
      Interest Period plus a margin of 1.5%.

      All LIBO Rate Loans shall bear interest from and including the first day
of the applicable Interest Period to (but not including) the last day of such
Interest Period at the interest rate determined as applicable to such LIBO Rate
Loan.


                                    -27-


   34



      SECTION III.2.2.  Post-Maturity Rates.  After the date any principal
amount of any Loan is due and payable (whether on the Stated Maturity Date,
upon acceleration or otherwise), or after any other monetary Obligation of the
Borrower shall have become due and payable, the Borrower shall pay, but only to
the extent permitted by law, interest (after as well as before judgment) on
such amounts (in the applicable Currency) at a rate per annum equal to the sum
of (a) the Alternate Base Rate, plus (b) the applicable margin for such Loan
pursuant to Section 3.2.1 plus (c) a margin of 2%.                          

      SECTION III.2.3.  Payment Dates.  Interest accrued on each Loan shall be
payable, without duplication:
                                    
           (a) on the Stated Maturity Date therefor;

           (b) on the date of any payment or prepayment, in whole or in part,
      of principal outstanding on such Loan;

           (c) with respect to Base Rate Loans, on each Monthly Payment Date
      occurring after the Effective Date;

           (d) with respect to LIBO Rate Loans, the last day of each applicable
      Interest Period (and, if such Interest Period shall exceed 90 days, on
      the 90th day of such Interest Period);

           (e) with respect to any Base Rate Loans converted into LIBO Rate
      Loans on a day when interest would not otherwise have been payable
      pursuant to clause (c), on the date of such conversion; and

           (f)  on that portion of any Loans the Stated Maturity Date of which
      is accelerated pursuant to Section 8.2 or Section 8.3, immediately upon
      such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount is due and
payable (whether on the Stated Maturity Date, upon acceleration or otherwise)
shall be payable upon demand.


                                    -28-


   35

       

      SECTION III.2.4.  Interest Act Provision.

           (a)  For the purposes of the Interest Act (Canada), whenever
      interest payable pursuant to this Agreement is calculated with respect to
      any monetary Obligation relating to Canadian Loans on the basis of a
      period other than a calendar year (the "Calculation Period"), each rate
      of interest determined pursuant to such calculation expressed as an
      annual rate is equivalent to such rate as so determined, multiplied by
      the actual number of days in the calendar year in which the same is to be
      ascertained and divided by the number of days in the Calculation Period.

           (b)  The principal of deemed reinvestment of interest with respect
      to any monetary Obligation relating to Canadian Loans shall not apply to
      any interest calculation under this Agreement.

           (c)  The rates of interest with respect to any monetary Obligation
      relating to Canadian Loans stipulated in this Agreement are intended to
      be nominal rates and not effective rates or yields.

      SECTION III.3.  Judgment Currency.  The Obligations of the Borrower and
each other Obligor in respect of any sum due to the Lender hereunder, under the
Notes or any other Loan Document shall, notwithstanding any judgment in a
currency (the "Judgment Currency") other than the currency in which such sum
was originally denominated (the "Original Currency"), be discharged only to the
extent that on the Business Day following receipt by the Lender of any sum
adjudged to be so due in the Judgment Currency, the Lender, in accordance with
normal banking procedures, purchases the Original Currency with the Judgment
Currency.  If the amount of Original Currency so purchased is less than the sum
originally due to the Lender, the Borrower agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify the Lender against such loss,
and if the amount of Original Currency so purchased exceeds the sum originally
due to the Lender, the Lender agrees to remit such excess to the Borrower.

      SECTION III.4.  Commitment Fee.  The Borrower agrees to pay to the Lender,
for the period (including any portion thereof when its Commitment is suspended
by reason of the Borrower's inability to satisfy any condition of Article V)
commencing on the Effective Date and continuing through the final Commitment
Termination Date, a commitment fee at the rate of 1/2 of 1% per annum on the
sum of the average daily unused portion of the Commitment Amount.  Such
commitment fees shall be payable by the Borrower in arrears on each Monthly
Payment Date, commencing with the first such day following the Effective Date,
and on the 



                                    -29-


   36

Commitment Termination Date.  All such fees shall be non-refundable.

                                 ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

      SECTION IV.1.  LIBO Rate Lending Unlawful.  If the Lender shall determine
(which determination shall, upon notice thereof to the Borrower, be conclusive
and binding on the Borrower) that the introduction of or any change in or in
the interpretation of any law makes it unlawful, or any central bank or other
governmental authority asserts that it is unlawful, for the Lender to make,
continue or maintain any Loan as, or to convert any Loan into, a LIBO Rate Loan
of a certain type, the obligations of the Lender to make, continue, maintain or
convert any such Loans shall, upon such determination, forthwith be suspended
until the Lender shall notify the Borrower that the circumstances causing such
suspension no longer exist, and all LIBO Rate Loans of such type shall
automatically convert into Base Rate Loans at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.
              
      SECTION IV.2.  Deposits Unavailable. If the Lender shall have determined
that
                                          
           (a) deposits in the applicable Currency, in the relevant amount and
      for the relevant Interest Period are not available to the Lender in its
      relevant market; or

           (b) by reason of circumstances affecting the Lender's relevant
      market, adequate means do not exist for ascertaining the interest rate
      applicable hereunder to LIBO Rate Loans of such type,

then, upon notice from the Lender to the Borrower, the obligations of the
Lender under Section 2.4 and Section 2.5 to make or continue any Loans as, or
to convert any Loans into, LIBO Rate Loans of such type shall forthwith be
suspended until the Lender shall notify the Borrower that the circumstances
causing such suspension no longer exist.

      SECTION IV.3.  Increased LIBO Rate Loan Costs, etc.  The Borrower
agrees to reimburse the Lender for any increase in the cost to the Lender of,
or any reduction in the amount of any sum receivable by the Lender in respect
of, making, continuing or maintaining (or of its obligation to make, continue
or maintain) any Loans as, or of converting (or of its obligation to convert)
any Loans into, LIBO Rate Loans. The Lender shall promptly notify the Borrower
in writing of the occurrence of any such 

                                    -30-


   37


event, such notice to state, in reasonable detail, the reasons therefor and the
additional amount required fully to compensate the Lender for such increased
cost or reduced amount.  Such additional amounts shall be payable by the
Borrower to the Lender within five days of its receipt of such notice, and such
notice shall, in the absence of manifest error, be conclusive and binding on
the Borrower.

      SECTION IV.4.  Funding Losses.  In the event the Lender shall incur any
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by the Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a LIBO
Rate Loan as a result of
                                  
           (a) any conversion or repayment or prepayment of the principal
      amount of any LIBO Rate Loans on a date other than the scheduled last day
      of the Interest Period applicable thereto, whether pursuant to Section
      3.1 or otherwise;

           (b) any Loans not being made as LIBO Rate Loans in accordance with
      the Borrowing Request therefor; or

           (c) any Loans not being continued as, or converted into, LIBO Rate
      Loans in accordance with the Continuation/Conversion Notice therefor,

then, upon the written notice of the Lender to the Borrower, the
Borrower shall, within five days of its receipt thereof, pay to the Lender such
amount as will (in the reasonable determination of the Lender) reimburse the
Lender for such loss or expense.  Such written notice (which shall include
calculations in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrower.

      SECTION IV.5.  Increased Capital Costs.  If any Change in Law after the
Effective Date affects or would affect the amount of capital required or
expected to be maintained by the Lender or any Person controlling the Lender,
and the Lender determines (in its sole and absolute discretion) that the rate
of return on its or such controlling Person's capital as a consequence of its
Commitment or the Loans made by the Lender is reduced to a level below that
which such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by the Lender to the Borrower, the Borrower shall immediately pay
directly to the Lender additional amounts sufficient to compensate the Lender
or such controlling Person for such reduction in rate of return; provided,
however, that (x) the Borrower shall not be required to compensate the Lender
or such controlling Person for amounts arising solely as a result of, or 



                                    -31-


   38

to the extent such amounts are in respect of, the Lender's delay in complying
with any such Change in Law and (y) the Borrower shall not be required to
compensate the Lender or such controlling Person for increased costs which the
Lender does not pass on to substantially all of its customers to whom the
Lender is, by agreement, entitled to pass on such costs.  A statement of the
Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrower.  In determining such amount, the Lender
may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable.

      SECTION IV.6.  Taxes.  All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or
other charges of any nature whatsoever, and all interest, penalties and
liabilities with respect thereto, imposed by any taxing authority, but
excluding franchise taxes and taxes imposed on or measured by the Lender's net
income or net receipts by reason of a connection between the Lender and the
relevant taxing jurisdiction (other than a connection arising solely from the
Lender having executed, delivered, performed its obligations or received any
payment under, or enforced any right arising in connection with, this Agreement
or any related transaction) (such non-excluded items being called "Taxes").  In
the event that any withholding or deduction from any payment to be made by the
Borrower hereunder is required in respect of any Taxes pursuant to any
applicable law, rule or regulation, then the Borrower will
 
           (a) pay directly to the relevant authority the full amount required
      to be so withheld or deducted;

           (b) promptly forward to the Lender an official receipt or other
      documentation satisfactory to the Lender evidencing such payment to such
      authority; and

           (c) pay to the Lender such additional amount or amounts as is
      necessary to ensure that the net amount actually received by the Lender
      will equal the full amount the Lender would have received had no such
      withholding or deduction been required.

      If the Lender is required by law at any time to pay any Taxes or make any
payment on account of Taxes on, in relation to or calculated by reference to
any sum received or receivable in connection with the Loans or any other amount
payable hereunder, or any liability for Taxes in respect of any such sum is
imposed, levied or assessed against the Lender, then the Borrower will
indemnify the Lender for the full amount of Taxes (including 
                         

                                    -32-


   39


Taxes attributable to any payment on account of such indemnification and any
interest, penalties and costs with respect to any such Taxes) actually (or, in
the event such Taxes are directly paid by the Borrower, deemed) paid by the
Lender, whether or not such Taxes were correctly or legally asserted.  Such
indemnification shall be made within 30 days of the demand of the Lender
therefor.  In the event that the Borrower makes any payment of Taxes in
connection with any such indemnification, the Borrower shall promptly forward
to the Lender an official receipt or other documentation satisfactory to the
Lender evidencing such payment to the applicable taxing authority.

      If the Borrower fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Lender the required receipts or other
required documentary evidence, the Borrower shall indemnify the Lender for any
incremental Taxes, interest or penalties that may become payable by the Lender
as a result of any such failure.

      The Lender shall, on or prior to the Effective Date, and at
such times as reasonably requested by the Borrower, deliver to the Borrower one
or more United States Internal Revenue Service Form 4224 (or successor forms or
such other forms), appropriately completed, to establish that payments to the
Lender in the then current taxable year of the Lender are exempt from
withholding or deduction of Taxes.

     If the Lender fails to deliver to the Borrower the appropriate form in
accordance with the immediately preceding sentence, other than as a result of a
change in law, then the Lender shall not be entitled to indemnification under
this Section with respect to U.S. withholding taxes that the Borrower is
required to pay in accordance with clause (a) above, and the Borrower shall not
be required to pay any additional amount in respect of such U.S. withholding
taxes to the Lender pursuant to clause (c) of this Section.

     SECTION IV.7.  Payments, Computations, etc.IV.7.  Payments, Computations,
etc.  All payments by the Borrower pursuant to this Agreement, the Note or any
other Loan Document shall be made by the Borrower to the Lender, without
setoff, deduction or counterclaim, not later than 11:00 a.m. San Francisco,
California time, on the date due, in same day or immediately available funds,
to such account as the Lender shall specify from time to time by notice to the
Borrower.  Funds received after that time shall be deemed to have been received
by the Lender on the next succeeding Business Day.  All interest and fees shall
be computed on the basis of the actual number of days (including the first day
but excluding the last day) occurring during the period for which such interest
or fee is payable over a year comprised of 360 days (or, in the case of
interest on a Base Rate Loan, 365 days or, if appropriate, 366 days).  Whenever
any payment to be made shall otherwise be due on 


                                    -33-


   40


a day which is not a Business Day, such payment shall (except as otherwise
required by clause (iii) of the proviso to the definition of the term "Interest
Period" with respect to LIBO Rate Loans) be made on the next succeeding
Business Day and such extension of time shall be included in computing interest
and fees, if any, in connection with such payment.

      SECTION IV.8.  Setoff.  The Lender shall, upon the occurrence of any
Default described in clauses (a) through (d) of Section 8.1.9 or upon the
occurrence of any other Event of Default and the declaration by the Lender
pursuant to Section 8.3 that all or any portion of the Loans and other
Obligations shall be due and payable, have the right to appropriate and apply
to the payment of the Obligations
owing to it (whether or not then due), and (as security for such Obligations)
the Borrower hereby grants to the Lender a continuing security interest in, any
and all balances, credits, deposits, accounts or moneys of the Borrower then or
thereafter maintained with the Lender.  The Lender agrees promptly to notify
the Borrower after any such setoff and application made by the Lender;
provided, however, that the failure to give such notice shall not affect the
validity of such setoff and application.  The rights of the Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff under applicable law or otherwise) which the Lender may have.

      SECTION IV.9.  Use of Proceeds.  The Borrower shall apply the proceeds of
each Borrowing in accordance with the fourth recital; without limiting the
foregoing, no proceeds of any Credit Extension will be used to acquire any
equity security of a class which is registered pursuant to Section 12 of the
Securities Exchange Act of 1934 or any "margin stock", as defined in F.R.S.

      Lender was solely as a result of the Lender's wilful misconduct, the
      Lender will reimburse the Borrower for any Indemnified Liabilities paid
      by the Borrower to the Lender in respect of such action);

           (c) any investigation, litigation or proceeding related to any

ITEM 6.15   SCHEDULE OF ROYALTIES


a.   Crofoot Mine.

     Net Proceeds Royalty in the production of minerals payable under Section 3
of the Mining Lease With Option to Purchase (patented mining claims) dated July
1, 1985, between Henry C. Crofoot, Jr., Trustee, and Hycroft Resources &
Development, Inc. ("Hycroft U. S."), and under Section 3 of the Mining Lease
With Option to Purchase (unpatented mining claims) dated July 1, 1985, among
Henry C. Crofoot, Jr. and Iola Jane Crofoot, his wife, and Daniel M. Crofoot
and Theodore A. Kolb and Alison Kolb, his wife, and Hycroft U. S., as amended
by certain amendment agreements, including the Fourth Amendment Agreement dated
effective January 1, 1996, and under the Deed of Unpatented Mining Claims With
Reservation of Net Proceeds Royalty and Sulphur Mineral Rights dated effective
January 1, 1996, and the Deed of Patented Mining Claims With Reservation of Net
Proceeds Royalty Sulphur Mineral Rights effective January 1, 1996 (collectively
the "Crofoot Agreements").

     Hycroft U. S. shall pay the Royalty Owner a production royalty of the
applicable percentage of Net Proceeds for all ores and minerals (except
sulphur) mined or otherwise recovered and removed from the Crofoot Mine
properties and sold by or for the account of Hycroft U. S. before or after
processing, smelting or refining ("Ores and Minerals").  The applicable royalty
percentages are:

            a. Seven percent (7%) of Net Proceeds derived from the
            sale of mercury; and

            b. Four percent (4%) of Net Proceeds derived from the
            sale of silver, gold and all other minerals (except
            sulphur).

     "Net Proceeds" means the amount actually received by Hycroft U. S. from
the sale of Ores and Minerals less, but only to the extent actually incurred
and borne by Hycroft U. S.:

     a.     Sales, use, gross receipts, severance and other taxes, if any,
payable with respect to severance, production, removal, sale or disposition of
Ores and Minerals, but excluding any taxes on net income;
            
     b.     Charges and costs, if any, for transportation to places where Ores
and Minerals are milled, treated, processed or otherwise beneficiated,
smeltered, refined and sold;
            
     c.     Charges and costs, if any, for milling, treatment, processing, or
other beneficiation, including but not limited to crushing, screening and all
mining costs; and  


   78

                                                                      Schedule I


     d.     Charges, costs and penalties, if any, for smelting, refining and
marketing.  In addition to the foregoing deductions, Hycroft U. S. shall
include in deductible costs depreciation of all equipment, billings and
facilities required by Hycroft U. S. to mine and process Ores and Minerals.
Unit depreciation charges shall be determined quarterly by dividing the Crofoot
Mine fixed assets by the total tons of ore reserves expected to be processed
through the Crofoot Mine, including any ores from other properties planned for
commingling through the Crofoot Mine plant.  The depreciation deducted on the
quarterly Crofoot Mine royalty statement shall be the product of the Crofoot
Mine ore tons processed during the quarter multiplied by the depreciation
charge per ton calculated above.  Upon termination of the Crofoot Mine
operations, the final royalty statement shall include the proceeds from sale or
salvage of the Crofoot Mine fixed assets prorated with respect to the total
tons and Crofoot Mine tons of ore processed through the Crofoot Mine plant.
Charges for interest, exploration, corporate overhead, depletion allowances and
property payments are specifically excluded from the Crofoot Mine Net Proceeds
royalty determination.

     If milling, treatment, processing or other beneficiation or smelting or
refining are carried on  in facilities owned or controlled, in whole or in
part, by Hycroft U. S., charges, costs and penalties for such operations,
including transportation, shall mean the amount that Hycroft U. S. would have
incurred if such operations were carried out at facilities not owned or
controlled by Hycroft U. S. then offering comparable custom services for
comparable products on prevailing terms.

     Hycroft U. S. may recover from production royalties as due to the Royalty
Owner, all advance royalty payments paid in accordance with the Crofoot
Agreements, as well as all other sums which are credited in favor of Hycroft U.
S. in accordance with the Crofoot Agreements against amounts otherwise due to
the Royalty Owner.  The Net Proceeds production royalties are payable on or
before the 30th day after the last day of each fiscal quarter during which
Hycroft U. S. receives payment for the sale of Ores and Minerals.  The Net
Proceeds production royalty payment obligation terminates and Hycroft U. S.
shall have no further obligation of any kind to the Royalty Owner when Hycroft
U. S. has paid a total of $12,800,000, including the sum of all purchase price
and advance and production royalty payments made pursuant to the Crofoot
Agreements and the conveyances executed and delivered in accordance with the
Crofoot Agreements.

     Under the Arbitrator's Rulings described in Item 1.1(6)(c) above, Hycroft
U.S. is obligated to F.W. Lewis, Inc. to deliver data and information and to
account for the production of ores and products from the Crofoot Mine and the
Lewis Mine as provided in the Commingling Plan, as defined in the Arbitrator's
Rulings.

b.   Lewis Mine.

     The Net Value production royalty payable to Frank W. Lewis and F.W. Lewis,
Inc. (collectively "Lewis"), is payable in accordance with Section 10 of the
Mining Lease dated January 1, 1983, between Frank W. Lewis, lessor, and The
Standard Slag Company, lessee, as assigned to Hycroft Lewis Mine, Inc.
("Hycroft Lewis"), and as amended by the:  (a) Lewis-

   79

                                                                      Schedule I

Hycroft Agreement dated January 10, 1989, among Frank W. Lewis, Hycroft Lewis
and Hycroft Resources & Development, Inc.; (b) Second Lewis-Hycroft Agreement
dated March 15, 1991, among Frank W. Lewis, Granges Inc., Hycroft Lewis and
Hycroft Resources & Development, Inc.; (c) Supplemental Memorandum of Mining
Lease dated January 29, 1997, between F.W. Lewis and Hycroft Lewis; and (d) the
Arbitrator's Rulings.  Under the Lewis Mine Mining Lease, Hycroft Lewis is
obligated to pay to Lewis royalties of seven and one-half percent (7.5%) of the
net value of all minerals and ores mined and sold by Hycroft Lewis from the
Lewis Mine, except with respect to gold.  With respect to gold, the Net Value
royalty percentage rate shall be determined as follows:




       ASSAY VALUE                                          NET VALUE ROYALTY RATE
                                                                  
 .050 oz., or less, of gold per ton                                   5%
More than .050 oz. but less than .060 oz. of gold per ton            6%
More than .060 oz. but less than .070 of gold per ton                7%
More than .070 oz. but less than .100 oz. of gold per ton            7-1/2%
More than .100 oz. but less than .120 oz of gold per ton             8%
More than .120 oz. but less than .140 oz of gold per ton             9%
More than .140 oz. or more of gold per ton                           10%



Assay Value is determined by dividing the actual gold recovered by the refinery
by the actual number of tons of ore produced during a calendar month, the
resultant figure being the Assay Value per ton.

     The term "Net Value" means the gross selling price of ores and
concentrates, less the cost of hauling ores and concentrates, from the Lewis
Mine to the market or smelter or other reduction works which purchases the ores
and concentrates, and freight charges from the shipping point to smelter or the
cost of trucking charges from the Lewis Mine direct to market or smelter, if
handled in that matter, together with smelting, milling and handling charges,
plus the cost of insurance on bullion shipments.  No other deductions shall be
permitted without Lewis' written consent.

     If ores are processed in a mill or processing plant owned, operated or
controlled by Hycroft Lewis (directly or indirectly) or milled upon the Lewis
Mine properties, no deductions shall be made for milling, processing or
transportation to the mill or other charges.  Payment of the Net Value
royalties for gold and silver shall be made to Lewis monthly on or before the
last day of each month on all minerals and ores sold during the preceding
calendar month.  Net Value of royalties for gold shall be determined on the
basis of total shipments to the refinery each month.  Hycroft Lewis shall
instruct the refiner or smelter to deposit seven and one-half percent (7.5%) of
the silver and other metals, together with the determined gold Net Value
royalty, into an account in Lewis' name.

     In each calendar year, Hycroft Lewis is entitled to credit the advance
minimum royalty payments paid under the Lewis Mine Mining Lease against the Net
Value production royalties

   80

                                                                      Schedule I

payable by Hycroft Lewis to Lewis for the year during which the advance minimum
royalty payment is paid.

     Under the Arbitrator's Rulings described in Item 1.1(6)(c) above, Hycroft
U.S. is obligated to F.W. Lewis, Inc. to deliver data and information and to
account for the production of ores and products from the Crofoot Mine and the
Lewis Mine as provided in the Commingling Plan, as defined in the Arbitrator's
Rulings.
