$16,000,000.00                                                 February 12, 2003

                                                                Denver, Colorado

      FOR VALUE RECEIVED, the undersigned Raleigh Mining International Limited,
a company organized and existing under the laws of the Province of Ontario,
Canada ("Maker"), hereby promises to pay to the order of Glamis de Mexico, S.A.
de C.V., a corporation organized and existing under the laws of Mexico, or any
subsequent holder of this Note ("Holder"), the sum of Sixteen Million Dollars
and No Cents (U.S. $16,000,000.00), with no interest thereon prior to default.
The undersigned Metallica Resources Inc., a Canadian federal corporation
("Guarantor"), is the direct corporate parent of Maker and is the guarantor of
Maker's obligations under this Note pursuant to that certain Guaranty dated
February 12, 2003, from Guarantor in favor of Holder.

      1. Payment of Note. This Note shall be payable as follows:

            (a) Five Million Dollars (US$5,000,000) shall be paid at the
earliest to occur of the following: (i) six (6) months from February 12, 2003,
or (B) three (3) business days following the date on which Maker and/or its
subsidiary, Minera San Xavier, S.A. de C.V., a company organized and existing
under the laws of Mexico ("MSX") and/or Guarantor both (X) completes and
receives the proceeds from a public or private debt or equity financing which
provides net proceeds to Maker or MSX of not less than Five Million Dollars
(US$5,000,000) and (Y) receives all permits and approvals necessary to commence

"Cerro San Pedro Project.).

            (b) Six Million Dollars (US$6,000,000) shall be paid twelve (12)
months from February 12, 2003, provided, however, that if Maker and Guarantor do
not have the financial ability to make such payment in cash, then Guarantor may
make all or part of that payment by delivering to Holder fully registered and
freely tradable common shares of Guarantor, together with such duly executed
stock powers or endorsements as are necessary to properly transfer the Guarantor
shares from Guarantor to Holder under the laws of Canada. The shares so
delivered shall be priced at the greatest allowable discount under applicable
Canadian and/or TSE rules from the average closing price of Guarantor's shares
on the Toronto Stock Exchange for twenty (20) trading days preceding the date on
which the payment became due to Holder. In the event that Guarantor elects to
deliver common shares to Holder in lieu of cash as provided in this paragraph
(b), the following terms and covenants shall apply:

                  (i)   In the event that Holder wishes to sell more than one
                        hundred thousand (100,000) of Guarantor's shares during
                        any ten (10) day trading period, Holder shall provide
                        Guarantor not less than forty -

<PAGE>

                        eight (48) hours prior notice to afford Guarantor the
                        opportunity to place the shares at the then-prevailing
                        market price. If Guarantor is unable to place the shares
                        or fails to respond to Holder within the forty-eight
                        (48) hour period, Holder shall be free to sell the
                        shares in the open market;

                  (ii)  In the event that Guarantor intends to conduct any
                        equity financing by way of public issue or private
                        placement while Holder still holds Guarantor shares,
                        Guarantor shall notify Holder of the same and shall
                        provide Holder the opportunity, exercisable at Holder's
                        sole discretion, to sell all or a portion of its shares
                        in the same transaction. The maximum number of Holder's
                        shares to be included in the equity financing shall be
                        the same percentage of the total shares to be issued as
                        the Holder's shares represent of the total issued and

<PAGE>

                              II. GRANT OF ROYALTY

      2.1 GRANT. FOR GOOD AND VALUABLE CONSIDERATION RECEIVED, the receipt and
sufficiency of which MSX hereby acknowledges, MSX grants to Glamis a royalty
(the "Royalty") on the Net Returns of all Minerals mined and removed from the
Properties and sold or deemed to have been sold by or for MSX, on the terms and
conditions herein specified.

      2.2 PERCENTAGE OF NET RETURNS.

            (a) Refined Gold. The percentage of Net Returns to be paid to Glamis
for refined gold produced from Minerals mined from the Properties shall be based
as follows:

<TABLE>
<CAPTION>
Monthly Average Gold
Returns
Price Per Ounce         Percentage of Net
---------------         -----------------
<S>                     <C>
Less than $325.00               0.0%
$325.00-$349.99                 0.5%
$350.00-$374.99                 1.0%
$375.00-$399.99                 1.5%
$400.00 or above                2.0%
</TABLE>

            (b) Other Products. In the event that MSX causes silver or other
refined metals other than refined gold to be produced from Minerals mined from
the Properties, or in the event that MSX sells raw ore, dore or concentrates
produced from Minerals mined from the Properties, the percentage of Net Returns
to be paid Glamis for such products shall be that percentage set forth in
Section 2.2(a) determined based on the price of gold as provided in Section 2.3.

      2.3 CALCULATION OF NET RETURNS. It is the intention of the Parties that
the Royalty be based upon the value, at the boundary of the Cerro San Pedro
Project Lands, of the Minerals produced and sold or deemed sold, determined by
reference to published prices for refined gold, silver and other metals and the
actual proceeds of sales for other Minerals, all as provided in Section 2.3(a)
below. Glamis acknowledges that it may be necessary or appropriate to process,
treat or upgrade Minerals of the Cerro San Pedro Project Lands before they are
sold and that, to determine the value of such Minerals at the boundary of the
Cerro San Pedro Project Lands, MSX shall be entitled to deduct all costs and
only those costs incurred or deemed incurred by MSX after the Minerals leave the
Cerro San Pedro Project Lands. Therefore, the Parties agree that as used this
Agreement, "Net Returns" shall mean Gross Proceeds (as defined in Section 2.3(a)
below) less Costs and Expenses (as defined in Section 2.3(b) below).

            (a) Gross Proceeds. As used in this Agreement, "Gross Proceeds"
shall mean and shall be calculated as follows:

                  (i) Refined Gold. If MSX causes refined gold to be produced
from Minerals mined from the Properties, the Royalty shall be paid on the
refined gold, as herein provided. For purposes of determining the Royalty, the
refined gold shall be deemed to have been sold at the Monthly Average Gold
Price, and the Gross Proceeds shall be determined by multiplying Gold Production
during the calendar month by the Monthly Average Gold Price for that month. As
used herein, "Gold Production" shall mean the quantity of refined gold
out-turned during the calendar month to MSX's pool account by an independent
third-party refinery from Minerals produced from the Properties, on either a
provisional or final settlement basis. As used herein, "Monthly Average Gold
Price" shall mean the average London Bullion Market

                                       -2-
<PAGE>

Association P.M. Gold Fix, calculated by dividing the sum of all such prices
reported for the month by the number of days for which such prices were
reported.

                  (ii) Refined Metals Other Than Gold. If MSX causes silver or
other refined metals other than refined gold to be produced from Minerals mined
from the Properties, the Royalty shall be paid on the refined metal produced, as
herein provided, and the Gross Proceeds shall be determined by multiplying
Refined Metal Production during the calendar month by the Monthly Average
Refined Metal Price for that month. As used herein, "Refined Metal Production"
shall mean the quantity of Refined Metal out-turned during the calendar month to
MSX's pool account by an independent third-party refinery from Minerals produced
from the Properties, on either a provisional or final settlement basis. As used
herein, "Monthly Average Refined Metal Price" shall mean the average New York
Refined Metal Price as published by Metals Week, calculated by dividing the sum
of all such prices reported for the calendar month by the number of days for
which such prices were reported.

                  (iii) Raw Ore, Dore or Concentrates. Subject to Section 2.4,
if MSX sells raw ore, dore or concentrates produced from Minerals mined from the
Properties, then the Gross Proceeds shall be equal to the amount of the proceeds
actually received by MSX during the calendar month from the sale of such raw
ore, dore or concentrates.

            (b) Costs and Expenses. As used in this Agreement, "Costs and
Expenses" shall mean all costs, charges, and expenses paid or deemed incurred by
MSX for or with respect to Minerals produced from the Properties, after such
Minerals leave the Cerro San Pedro Project Lands, including, without limitation:

                  (i) charges for treatment in the smelting and refining
processes (including handling, processing, interest, provisional settlement
fees, sampling, assaying and representation costs, penalties and other processor
deductions);

                  (ii) actual costs of transportation (including loading,
freight, insurance, security, transaction taxes, handling, port, demurrage,
delay, and forwarding expenses incurred by reason of or in the course of such
transportation) of Minerals (with respect to which Royalty is paid) from the
Cerro San Pedro Project Lands to the place of treatment as described in Section
2.3(b)(i) above and then to the place of sale;

                  (iii) costs or charges of any nature for or in connection with
insurance, storage, or representation at a smelter or refinery for Minerals;

                  (iv) actual sales and brokerage costs paid to third-parties,
if any, on Minerals for which the Royalty is based on actual proceeds received
by MSX and an allowance for reasonable sales and brokerage costs paid to
third-parties, if any, for refined metals that are subject to the Royalty
provided in Section 2.3(a)(i),(ii) and (iii); and

                  (v) sales, use, severance and any other tax based directly
upon, measured by and actually assessed against the value or quantity of
Minerals produced, but excluding any and all taxes and any payments, taxes, and
fees: (X) based upon the net or gross income of MSX or any owner or operator of
the Properties or the Cerro San Pedro Project; (Y) based upon the value of the
Properties or the Cerro San Pedro Project, the privilege of doing business, or
other similarly based payments, taxes or fees; and (Z) not based directly upon
and actually assessed against the value or quantity of Minerals produced.

                                      - 3 -
<PAGE>

In the event that smelting and/or refining are carried out in facilities owned
or controlled by MSX or any Affiliate of MSX, then charges, costs and penalties
for such operations, including without limitation for loading, transportation
and associated insurance, shall mean the amount that MSX would have incurred if
such operations were carried out at facilities not owned or controlled by MSX or
any Affiliate of MSX then offering comparable custom services for comparable
products on prevailing terms.

      2.4 SALES TO AFFILIATES. MSX shall be permitted to sell Minerals from the
Properties in the form of raw ore, dore, or concentrates to an Affiliate of MSX,
provided that such sales shall be considered, solely for the purpose of
computing the Royalty, to have been sold at prices and on terms no less
favorable than those that would be extended to an unaffiliated third party under
similar circumstances.

      2.5 COMMINGLING. MSX shall have the right of mixing or commingling, at any
location and either underground or at the surface, Minerals produced from the
Properties with Minerals produced from other lands, provided that MSX shall
determine the weight, grade or volume of, sample and analyze all such Minerals
before the same are so mixed or commingled. Any such determination of weight,
grade or volume, sampling and analysis shall be made in accordance with sound
sampling and analytic practices, and procedures. The weight, grade or volume and
the analysis so derived shall be used as the basis of allocation of Royalty
payable to Glamis hereunder in the event of a sale by MSX of Minerals so mixed
or commingled.

                             III. PAYMENT OF ROYALTY

      3.1 ACCRUAL AND PAYMENT OF ROYALTY. The obligation to pay Royalty shall
accrue upon the out-turn of refined metals meeting the requirements of the
specified published price to MSX's account or the sooner sale of unrefined
metals, dore, concentrates, ores or other mineral products, as herein provided.
Royalties shall become due and payable quarterly on the fifteenth (15th) day of
the month next following the end of the calendar month in which the same accrue.
In the event that MSX determines that any payment of Royalty was underpaid or
overpaid, MSX shall correct such overpayment or underpayment by adjustment to
the amount of the next subsequent payment of Royalty following such
determination.

      3.2 PROVISIONAL STATEMENTS. Where out-turn of refined metals is made by an
independent third-party refinery on a provisional basis, the Gross Proceeds and
the Royalty paid to Glamis for such metals in any month shall be based upon the
amount of refined metal credited by such provisional settlement, but shall be
adjusted in subsequent statements to account for the amount of refined metal
established by final settlement by the refinery.

      3.3 MONTHLY STATEMENTS. Royalty payments shall be accompanied by a
statement showing in reasonable detail the following: (a) the quantities and
grades of the refined metals, dore, concentrates, other mineral products, or
ores produced and sold or deemed to have been sold by MSX in the preceding
calendar month; (b) the average monthly price determined as provided in Section
2.3(a)(i) and (ii) for refined metals on which Royalty is due; (c) the proceeds
of sale for other Minerals on which Royalty is due, determined as provided in
Section 2.3(a)(iii) and Section 2.4; (d) Costs and Expenses; and (e) other
pertinent information in sufficient detail to explain the calculation of the
Royalty payment. Monthly royalty statements also shall list the quantity and
quality of any dore that has been retained as inventory for more than sixty (60)
days.

                                       -4-
<PAGE>

      3.4 GLAMIS' ELECTION WITH RESPECT TO INVENTORY UPON RECEIPT OF MONTHLY
STATEMENT. Glamis shall have fifteen (15) days after receipt of each monthly
statement rendered to it pursuant to Section 3.3 to either:

            (a) request that inventoried dore be deemed sold as provided in
Section 2.3(a)(i) and (ii) above as of the fifteenth (15th) day of the month for
which the monthly statement was rendered, utilizing the mine weights and assays
for such dore and utilizing a deemed charge for all Costs and Expenses as
specified in Section 2.4 above which shall be based upon the most recent charges
to MSX for such items; or

            (b) elect to wait until the time that refined gold or silver from
such dore is actually out-turned to MSX or such dore is sooner sold by MSX.

The failure of Glamis to respond within the fifteen (15) day period shall be
deemed to be an election under (b) above. No Royalty shall be due with respect
to stockpiles of ores or concentrates unless and until such ores or concentrates
are actually sold.

      3.5 OBJECTIONS TO ROYALTY PAYMENTS/AUDITS. All Royalty Payments made
during each calendar year shall be considered final and in full satisfaction of
all obligations of MSX with respect thereto, unless Glamis gives MSX written
notice describing and setting forth a specific objection to the determination
thereof within ninety (90) days following the end of the calendar year during
which such Royalties were paid. During the ninety (90) day period, Glamis shall
have the right, upon reasonable notice and at a reasonable time, to have MSX's
accounts and records relating to the calculation of the Royalties paid during
such calendar year audited by Glamis or an independent certified public
accountant acceptable to Glamis and MSX. If such audit determines that there has
been a deficiency or an excess in the payment made to Glamis, such deficiency or
excess shall be resolved by adjusting the next monthly Royalty payment due
hereunder, or by direct payment if no monthly Royalty payment follows the audit
determination. Glamis shall pay all costs of such audit unless a deficiency of
ten percent (10%) or more of the amount due to Glamis is determined to exist.
MSX shall pay the costs of such audit if a deficiency of ten percent (10%) or
more of the amount due to Glamis is determined to exist. All books and records
used by MSX to calculate Royalties due hereunder shall be kept in accordance
with generally accepted account principles, consistently applied. Failure on the
part of Glamis to make a claim on MSX for adjustment within such ninety (90) day
period shall establish the correctness and preclude the filing of exceptions
thereto or making of claims for adjustment thereon.

      3.6 TAKE IN KIND ELECTION. At the beginning of each calendar year during
which MSX may produce Minerals from the Properties, Glamis may elect to take its
Royalty in kind for the following calendar year. Glamis must notify MSX of its

      4.3 FURTHER ASSURANCES AND CONTINUING OBLIGATIONS. MSX agrees to execute

acknowledged by the Parties that such registration may not be possible.
Therefore, it is further understood and agreed that MSX shall remain liable for
all Net Returns that may become due to Glamis under this Royalty Deed,
regardless of any transfers by MSX, its successors or assigns, of all or any
interest in the Cerro San Pedro Project or in the Properties.

any way to the calculation of Royalty payable pursuant to this Deed, mining or

accordance with the laws of the State of Nevada, without regard to choice or
conflict of laws rules or principles. The exclusive venue for any action brought
to enforce or interpret this Agreement shall be Reno, Nevada. The Parties may
bring such an action in any federal or state court in Reno, Nevada. The Parties
