ITEM 1. CHANGES IN CONTROL OF REGISTRANT

     Pursuant to a Stock Purchase Agreement dated September 1, 1999 (the "Stock
Purchase Agreement") between MK Gold Company (the "Company") and Leucadia
National Corporation ("Leucadia"), Leucadia has agreed to purchase, subject to
certain conditions, and the Company has agreed to sell, subject to certain
conditions, 18,058,635 shares (the "Shares") of the authorized but unissued
shares of Common Stock of the Company at the price of $0.8753 per share,
representing the book value of the Shares as at June 30, 1999.

     The purpose of the sale of the Shares to Leucadia was to provide the
Company with a portion of the funds necessary for the Company to acquire the
entire share capital and subordinated debt of RioMin Exploraciones SA
("Riomin"), as more fully described in Item 2 of this report. Because funding
for this acquisition was required before the sale of the Shares could be
completed, the Company has borrowed $15,806,723 from Leucadia pursuant to a
Promissory Note dated September 1, 1999 (the "Promissory Note"). The Promissory
Note is due September 1, 2001 and bears interest at a rate of 8% per annum for a
period of 60 days, increasing to 12% thereafter. Interest is payable
semi-annually in arrears commencing March 31, 2000. The Promissory Note will be
used by Leucadia to pay the purchase price for the Shares upon issuance of the
Shares.

     Upon consummation of the transactions contemplated by the Stock Purchase
Agreement, Leucadia will beneficially own 27,058,635 shares of Common Stock of
the Company, which will represent approximately 72.5% of the Common Stock to be
outstanding at that time. Prior to the purchase of the Shares, Leucadia
beneficially owns 9,000,000 shares of Common Stock of the Company, representing
approximately 46.7% of the Company's outstanding Common Stock.

     Leucadia has informed the Company that its source of funding of the
Promissory Note was its working capital. Each party's obligation to consummate
the transactions contemplated by the Stock Purchase Agreement is subject to
certain conditions, including the expiration or termination of applicable
waiting periods under the Hart-Scott Rodino Antitrust Improvements Act of 1976,
as amended.

     The foregoing description is qualified by reference to the Stock Purchase
Agreement and the Promissory Note, which are incorporated by reference as
exhibits to this report.

ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

     On September 1, 1999, pursuant to a Sale and Purchase Agreement, the
Company acquired the entire share capital and subordinated debt of Riomin (the
"Acquisition") from Rio Tinto plc ("Rio Tinto"). Riomin holds the exploration
and mining rights to the Las Cruces copper deposit in the pyrite belt of Spain
(the "Project"). The Project is in the exploration and development phase and no
copper is currently being produced from the Project. Actual mining will be
subject to permitting, engineering and construction.

                                       2
<PAGE>
     The aggregate purchase price for the Acquisition was $42 million in cash.
In addition, Rio Tinto will be entitled to receive a 1.5% royalty on any copper
sales from the Project at a price exceeding $0.80 per pound. The Company
obtained funding for the Acquisition through (i) borrowings of $20 million
pursuant to an existing Credit Agreement, dated as of March 1, 1998 (the "Credit
Agreement"), between Leucadia and the Company, (ii) the borrowing from Leucadia
of $15,806,723 in connection with the pending stock purchase described in Item 1
of this report and (iii) $6,193,277 from the Company's working capital. The
aggregate purchase price for the Acquisition was determined pursuant to
negotiations between the Company and Rio Tinto.

     In connection with the Acquisition, the Company has granted Straits
Resources Ltd., Sydney, Australia, a one-year option to purchase 35% of Riomin
at the Company's cost, plus interest.

     Prior to the sale, there were no material relationships between Riomin or
Rio Tinto and the Company or its affiliates, directors or officers or any
associate of any director or officer of the Company.

     The foregoing description is qualified in its entirety by reference to the
Sale and Purchase Agreement, which is incorporated by reference as an exhibit to
this report.

     (a)  The Company intends to file financial statements of Riomin no later
          than November 15, 1999.

     the date of such written notice, or

          (i)  if legal proceedings have not been instituted in respect of such

<PAGE>
          (ii) in the event that the Vendor shall make in respect thereof a
               request pursuant to clause 5.12(a)(ii), if legal proceedings have
               not been instituted by the Purchaser in respect of such claim by
               the due service of process on the Vendor within three months of
               the date on which pursuant to clause 5.12(a)(ii) judgement is
               given by a court of competent jurisdiction in respect of such
               proceedings as shall have been instituted by the Purchaser
               pursuant to such request or the date settlement is reached in
               such third party proceedings with the consent of the Vendor or on
               which the Vendor and the Purchaser agree that proceedings or
               other action against the third party shall be abandoned.

     For the purpose of this clause 5.3 legal proceedings shall not be deemed to
     have been commenced unless they shall have been properly issued and validly
     served upon the Vendor.

          for this paragraph) have been less than US$25,000;

     (b)  unless and until and only to the extent that the liability in respect
          of that claim (not being a claim for which liability is excluded under
          sub-clause 5.4(a) above) when aggregated with the liability of the
          Vendor in respect of all other claims shall exceed US$300,000.

5.5  Save in the case of fraud or fraudulent concealment the aggregate liability
     of the Vendor in respect of all claims under this Agreement shall not in
     any circumstances exceed US$42,000,000.

5.6  The Vendor shall be under no liability whatsoever in respect of any claim
     under the Warranties if the facts or circumstances giving rise thereto are
     fully and fairly disclosed in the Disclosure Letter, any of the documents
     contained in the Data Room or provided for or stated to be exceptions under
     the terms of this agreement or are otherwise known to the Purchaser at the
     date hereof.

5.7  No liability (whether in contract, tort or otherwise) shall attach to the
     Vendor in respect of any claim under the Warranties to the extent that:-

     (a)  the claim or the events giving rise to the claim would not have arisen
          but for an act, omission or transaction of the Purchaser or which
          would not have arisen but for any claim, election or surrender or
          disclaimer made or omitted to be made or notice or consent given or
          omitted to be given by the Purchaser under the provisions of any
          statutes relating to Tax;

     (b)  the claim is based upon a liability which is contingent only, unless
          and until such contingent liability becomes an actual liability or
          until the same is finally adjudicated;


<PAGE>
     (c)  provision or reserve in respect of the matter giving rise to the claim
          shall have been made in the Accounts or to the extent that the matter
          giving rise to the claim shall have been noted in the Accounts;

     (d)  the claim occurs wholly or partly out of or the amount thereof is
          increased as a result of:-

          (i)    any change in the accounting principles or practices of the
                 Purchaser introduced or having effect after the date of this
                 agreement unless the same is introduced to bring the accounting
                 principles and practices into line with generally accepted
                 accounting principles and practices in Spain in relation to a
                 business of the type carried on by the Company; or

          (ii)   any increase in the rates of taxation made after the date
                 hereof; or

          (iii)  any change in law or regulation or in its interpretation or
                 administration by the Spanish courts, by the Spanish taxation
                 authorities or by any other fiscal, monetary or regulatory
                 authority (whether or not having the force of law);

     (e)  the loss or damage giving rise to the claim is recoverable by the
          Purchaser under any policy of insurance or would have been so
          recoverable but for any change in the terms of insurance since the
          date of this agreement; or

     (f)  the claim relates to a claim or liability for taxation and would not
          have arisen but for any winding-up or cessation after Completion of
          any business or trade carried on by the Company or the Purchaser.

5.8  The Purchaser shall promptly:-

     (a)  inform the Vendor in writing of any fact, matter, event or
          circumstance which comes to its notice whereby it appears that the
          Vendor is or may be liable to make any payment in respect of any claim
          under the Warranties or whereby it appears the Purchaser's Group shall
          become or may become entitled to recover from some other person a sum
          which is referable to a payment already made by the Vendor in respect
          of such a claim; and

     (b)  thereafter keep the Vendors fully informed of all developments in
          relation thereto; and

     (c)  provide all such information and documentation (no matter how it is
          recorded or stored) as the Vendor shall request in connection
          therewith and also in connection with any proceedings instituted by or
          against the Purchaser's Group under clause 5.12 and which information
          or documentation is not the subject to legal professional privilege or


<PAGE>
          confidential information created or brought into existence by the
          Purchaser's Group since Completion.

5.9  The only remedies available to the Purchaser in respect of this agreement
     together with any other documents referred to in this agreement (the
     "Transaction Documents") are damages for breach of contract (subject to the
     limitations set out in this agreement) and, for the avoidance of doubt, it
     does not have any right to rescind or terminate any Transaction Documents
     either for breach of contract or for negligent or innocent
     misrepresentation or otherwise.

5.10 The Purchaser hereby represents and warrants that it has no knowledge of
     any fact which might lead to claims against the Vendor under the
     Warranties.

5.11 The Purchaser's Group will take or procure the taking of all such steps and
     action as are necessary or as the Vendor may reasonably require in order to
     mitigate any claim under the Warranties and the Purchaser's Group shall act
     in accordance with such request subject to the Company and the Purchaser
     being indemnified and adequately secured to the reasonable satisfaction of
     the Purchaser by the Vendor against all reasonable costs and expenses which
     may properly be incurred by reason of such action, including reasonable
     legal costs and expenses on a full indemnity basis. Nothing in this
     agreement shall or shall be deemed to relieve the Purchaser of any common
     law or other duty to mitigate any loss or damage incurred by it.

5.12 (a)  This clause shall apply in circumstances where:-

          (i)    any claim is made against the Purchaser which may give rise to
                 a claim by the Purchaser against the Vendor under the
                 Warranties; or

          (ii)   the Purchaser is or may be entitled to make any recovery from
                 some other person any sum in respect of any facts or
                 circumstances by reference to which the Purchaser has or may
                 have a claim against the Vendor under the Warranties; or

          (iii)  the Vendor shall have paid to the Purchaser an amount in
                 respect of a claim under the Warranties and subsequent to the
                 making of such payment the Purchaser becomes or shall become
                 entitled to recover from some other person a sum which is
                 referable to that payment.

     (b)  The Purchaser shall and, where appropriate, the Company shall:-

          (i)    (prior to taking any action against the Vendor under the
                 Warranties in the case of clause 5.12(a)(i) and clause
                 5.12(a)(ii) and subject to the Company and the Purchaser being
                 indemnified and adequately secured to the reasonable
                 satisfaction of the Purchaser by the Vendor against all
                 reasonable costs and expenses which may properly be incurred


<PAGE>
                 by reason of such action) promptly and diligently take all such
                 action (including reasonable legal costs and expenses on a full
                 indemnity basis) as the Vendor may reasonably request including
                 the institution of proceedings and the instruction of
                 professional advisers approved by the Vendor (such approval not
                 to be unreasonably withheld) to act on behalf of the Company
                 and the Purchaser (as the case may be) to avoid, dispute,
                 resist, compromise, defend or appeal against any such claim
                 against the Purchaser as is referred to in clause 5.12(a)(i) or
                 to make such recovery by the Purchaser as is referred to in
                 clause 5.12(a)(ii) or clause 5.12(a)(iii), as the case may be,
                 in accordance with the instructions of the Vendor to the intent
                 that such action shall be delegated entirely to the Vendor
                 provided that at all times the Purchaser and the Company shall
                 continue to be indemnified and secured to the reasonable
                 satisfaction of the Purchaser provided that, however, either:

                 (A)   the Purchaser and/or the Company (as the case may be)
                       must consent in writing to the terms and conditions of
                       any settlement or compromise of any claim or dispute; or

                 (B)   (1)  the Purchaser and/or the Company (as the case may
                            be) must receive a full release, signed by all other
                            parties to the dispute or claim, releasing the
                            Purchaser and/or the Company (as the case may be)
                            from all claims and liability arising out of the
                            claim or dispute; and

                       (2)  the settlement or compromise of the claim or dispute
                            must not hinder or impair the ability of the
                            Purchaser and/or the Company (as the case may be) to
                            carry on its or their business or businesses.

          (ii)   so long as the Vendor shall have given adequate security
                 therefor not settle or compromise any liability or claim to
                 which such action is referable without the prior written
                 consent of the Vendor which consent shall not be unreasonably
                 withheld or delayed; or

          (iii)  in the case of clause 5.12(a)(iii) only, promptly repay to the
                 Vendor an amount equal to the amount so recovered or, if lower,
                 the amount paid by the Vendor to the Purchaser.

5.13 The Vendor hereby agrees to indemnify and keep indemnified the Purchaser
     against any loss, liability, cost or expense (including, without
     limitation, environmental and rehabilitation liabilities) it may incur as a
     direct result of any act or omission of the Vendor and/or the Company prior
     to Completion in relation to any investigation permits (other than the
     Investigation Permits) held from time to time by the Company.

     (b)  required by law or the rules of the London Stock Exchange or other

     provided that this clause 7.1 does not apply to announcements,
     communications or circulars made or sent by the Purchaser after Completion
     to customers, clients or suppliers of any Group Company to the extent that
     it informs them of the Purchaser's acquisition of the Shares or to any
     announcements containing only information which has become generally
     available.

7.2  The restrictions contained in clause 7.1 shall apply without limit of time

                                   ----------

                                     Royalty

1.   A Royalty of 1.5% (one and a half per cent) of "Sales Revenue" shall be
     paid by Purchaser to Vendor in respect of all sales realised in any
     calendar month in which the "Trigger Price" is exceeded. For the purposes
     of this Schedule, the "Trigger Price" is exceeded when the official monthly
     average LME Cash Settlement price for Grade A copper is equivalent to or
     greater than $0.80 per pound of copper.

2.   "Sales Revenue" shall mean:-

     (A)  in the case of sales of copper metal, whichever is the higher of:

          either   (1) the invoiced volume of metal sold in any month multiplied
                       by the actual official monthly average LME Cash
                       Settlement price for Grade A copper for that relevant
                       month; or

                   (2) the invoiced volume of metal sold in any month
                       multiplied by the actual price realised by the Purchaser
                       (including any premium),

          for all metal produced by the Purchaser from ore mined from the land
          which is the subject of the Investigation Permits ("the Permit Land")

     (B)  in the case of sales of copper produced from the Permit Land which is
          sold in any form which is partly or not wholly processed, "Sales
          Revenue" shall mean whichever is the higher of:

          either   (1) the actual final invoice value for the volume of partly
                       processed copper sold in the relevant month. (For these
                       purposes, final invoice value shall mean the full value
                       of the cargo as adjusted for final weight, assays and
                       prices); or

                   (2) the value for the volume of partly processed copper sold
                       which would have been invoiced if the copper price used
                       in calculating the relevant amount was the actual
                       official monthly LME Cash Settlement price for Grade A
                       copper for the month in which the final invoice is
                       settled,

          for all partly processed copper produced by the Purchaser and mined
          from the land which is the subject of the Permit Land.

     In calculating the Sales Revenue for the purposes of paragraphs 2(A) and
     (B) above the Purchaser may deduct the following costs and expenditures:


<PAGE>
     (a)  freight, transportation and insurance costs of copper metal from the
          treatment plant and/or refinery to the point of sale;

     (b)  the amount of any royalties payable to the Spanish government and any
          other royalty payable in respect of ore mined, or copper metal
          produced from the Permit Land;

     (c)  sales commissions and other sales representation costs in connection
          with the sales of copper metal incurred on an arms-length basis in the
          ordinary course of business by the Purchaser,

     but such costs and expenditures shall not include operating costs
     (including without limitation mining, operating, refining, financing and
     related costs, and administration costs).

     In addition, in calculating the Sales Revenue for the purposes of paragraph
     2(B) above the Purchaser may deduct smelting and refining charges or such
     other deductions which are directly related to the further processing of
     the product into cathode copper.

3.   The Purchaser must maintain proper records of:

     (a)  tonnes of ore mined;

     (b)  information or returns regarding the payment of royalties, taxes or
          other payments to the Spanish government in respect of mining on the
          Permit Land;

     (c)  all other information necessary to determine "Sales Revenue" and to
          allow Royalty to be calculated; and

     (d)  all amounts paid by the Purchaser to the Vendor under paragraph 4
          below,

     together called the "Purchaser's Records".

4.   On each occasion the Purchaser is obliged to provide a statement under
     paragraph 5, and within 12 months thereafter, the Vendor may at its own
     expense:

     (a)  upon reasonable notice to the Purchaser request and have access during
          the Company's normal business hours at premises maintained by the
          Company in Spain to inspect the Purchaser's Records;

     (b)  require an audit of the Purchaser's Records to be performed by an
          auditor nominated by the Vendor. Any such audit of the Purchaser's
          records shall be conducted in accordance with accounting principles
          generally applied in Spain;


<PAGE>
     (c)  if such an audit discloses a discrepancy between the amount paid by
          the Purchaser pursuant to paragraph 5 and the amount which should have
          been paid pursuant to that paragraph, then if there has been an
          underpayment by the Purchaser, the Purchaser must pay the underpayment
          immediately, and if there has been an overpayment, then the
          overpayment may be set off by the Purchaser against any further
          amounts payable to the Vendor pursuant to paragraph 5.

5.   Within 21 (twenty one) days of the end of any applicable calendar month in
     which the "Trigger Price" has been exceeded, the Purchaser will send to the
     Vendor a statement summarising:

     (a)  the quantity of copper metal (expressed in lbs) produced during the
          calendar month in which the "Trigger Price" is effective from ore
          mined from the Permit Land;

     (b)  the Purchaser's calculation of "Sales Revenue" for the respective
          calendar month; and

     (c)  the quantity of copper (metal and concentrate) sold during the
          relevant month.

     The Purchaser shall at the same time pay the Vendor the relevant Royalty in
     US dollars by telegraphic transfer to a bank to be nominated by Vendor.

IV.  THE COMPANY'S REPRESENTATIONS AND WARRANTIES
     --------------------------------------------

     The Company makes the following representations and warranties to LUK, each
and all of which shall survive the execution and delivery of this Agreement and
the Closing (as defined herein) hereunder:

     4.1 Organization. The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the State of
Delaware with corporate power and authority to own, lease and operate its
properties and to conduct its business as currently being and as proposed to be
conducted. The Company is qualified as a foreign corporation to transact
business in Utah and in any other jurisdiction where it is required to be so
qualified, except where the failure to be so qualified would not have a material
adverse effect on the condition, financial or otherwise, or the results of
operations, business or business prospects of the Company and its subsidiaries
taken as a whole (a "Material Adverse Effect").

     4.2 Due Authorization. The Company has the requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by the
Company and, assuming that this Agreement has been duly executed and delivered
by LUK, constitutes a legal, valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms, except as rights
to indemnity hereunder may be limited by federal or state securities laws and
except as enforceability may be limited by bankruptcy,

                                       2
<PAGE>
insolvency, fraudulent conveyance, moratorium, reorganization and similar laws
relating to or affecting creditors' rights generally and general principles of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law).

     4.3 Authorized and Outstanding Shares of Capital Stock. The authorized
capital stock of the Company consists of forty million (40,000,000) shares of
Common Stock, of which 19,261,365 shares currently are issued and outstanding as
of the date hereof. Except for 2,500,000 shares issuable under the Company's
Stock Incentive Plan (the "Stock Incentive Plan") and 180,000 shares issuable
under the Company's Stock Option Plan for Non-Employee Directors (the
"Non-Employee Director Plan"), no subscription, warrant, option or other right
to purchase or acquire any shares of any class of capital stock of Company or
securities convertible into such capital stock is authorized or outstanding, and
other than this Agreement or pursuant to outstanding stock options issued under
the Stock Incentive Plan and the Non-Employee Director Plan, there is no
commitment of Company to issue any such shares, warrants, options or other such
rights or securities.

     4.4 Authorization and Issuance of Securities. The issuance of the
Securities has been duly authorized and, upon delivery to LUK of certificates
therefor against payment in accordance with the terms hereof, the Securities
will have been validly issued and fully paid and non-assessable, free and clear
of all pledges, liens, encumbrances and preemptive rights.

     4.5 Subsidiary Organizations. Each subsidiary of the Company has been duly
organized and is validly existing and in good standing under the laws of their
jurisdictions of incorporation, has corporate power and authority to own, lease
and operate its properties and to conduct its business as currently being and as
proposed to be conducted and is qualified as a foreign entity to transact
business in each other jurisdiction where the failure to do so would have a
Material Adverse Effect. All of the issued and outstanding capital stock of each
such subsidiary has been duly authorized and validly issued, is fully paid and
nonassessable and is owned directly by the Company.

     4.6 No Other Rights. The issuance of the Securities is not subject to
preemptive or other similar rights.

     4.7 No Conflicts. Neither the Company nor any of its subsidiaries is in
violation of its charter or in default in the performance or observance of any
material obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument to which the Company or any of its subsidiaries is a party or by
which it or any of them may be bound, or to which any of the property or assets
of the Company or any of its subsidiaries is subject, the effect of which
default in performance or observance would have a Material Adverse Effect. None
of the execution and delivery of this Agreement will conflict with or constitute
a breach of, or default under, or result in the creation or imposition of any
lien, charge or encumbrance upon any property or assets of the Company or any of
its subsidiaries pursuant to, any contract, indenture, mortgage, loan agreement,
note, lease or

                                       3
<PAGE>
other agreement or instrument to which the Company or any of its subsidiaries is
a party or by which it or any of them may be bound, or to which any of the
property or assets of the Company or any of its subsidiaries is subject, nor
will such action result in any violation of the provisions of the certificate of
incorporation or by-laws of the Company or any applicable law, administrative
regulation or administrative or court decree.

     4.8 No Consents. Except for filings required under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 as amended (the "HSR Act"), the Securities
Act of 1933, as amended (the "Securities Act"), the Securities Exchange Act of
1934, as amended (the "Exchange Act") or state securities or "blue sky" laws, no
authorization, approval or consent of, or filing with, any court or governmental
authority or agency, is necessary or required in connection with the sale of the
Securities hereunder or the transactions contemplated hereby.

     4.9 Litigation. There is no action, suit or proceeding before or by any
court or governmental agency or body, domestic or foreign, now pending or, to
the best knowledge of the Company, threatened, against or affecting the Company
or any of its subsidiaries, which is reasonably likely to have a Material
Adverse Effect. There is no action, suit or proceeding before or by any court or
governmental agency or body, domestic or foreign, now pending or, to the best
knowledge of the Company, threatened, which would materially and adversely
affect the consummation of the transactions contemplated by this Agreement.

V.   LUK's REPRESENTATIONS AND WARRANTIES
     ------------------------------------

     LUK makes the following representations and warranties to the Company, each
and all of which shall survive the execution and delivery of this Agreement and
the Closing hereunder:

     5.1 Organization. LUK has been duly incorporated and is validly existing as
a corporation in good standing under the laws of the State of New York with
corporate power and authority to own, lease and operate its properties and to
conduct its business as currently being and as proposed to be conducted and to
enter into and perform its obligations under this Agreement. LUK is qualified as
a foreign corporation to transact business in each jurisdiction where it is
required to be so qualified, except where the failure to be so qualified would
not have a material adverse effect on the business, financial condition or
results of operation of LUK and its subsidiaries taken as a whole.

     5.2 Due Authorization. LUK has the requisite corporate power and authority
to enter into this Agreement and consummate the transactions contemplated
hereby. This Agreement and the transactions contemplated hereby have each been
duly authorized, executed and delivered by LUK, and this Agreement constitutes a
legal, valid and binding agreement of the Company, enforceable against LUK in
accordance with its terms, except as rights to indemnity hereunder may be
limited by federal or state securities laws and except as enforceability may be
limited by bankruptcy, insolvency,

                                       4
<PAGE>
fraudulent conveyance, moratorium, reorganization and similar laws relating to
or affecting creditors' rights generally and general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

     5.3 No Conflicts. LUK is not in violation of its certificate of
incorporation or in default in the performance or observance of any material
obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument to which LUK is a party or by which it may be bound, or to which any
of the property or assets of LUK or any of its subsidiaries is subject, the
effect of which default in performance or observance would have a material
adverse effect on the condition, financial or otherwise, or the results of
operations, business or business prospects of LUK and its subsidiaries
considered as one enterprise. The execution and delivery of this Agreement will
not conflict with or constitute a breach of, or default under, or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the LUK or any of its subsidiaries pursuant to any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument to which LUK or any of its subsidiaries is a party or by which it or
any of them may be bound, or to which any of the property or assets of LUK or
any of its subsidiaries is subject, nor will such action result in any violation
of the provisions of the certificate of incorporation or by-laws of LUK or any
applicable law, administrative regulation or administrative or court decree.

     5.4 No Consents. Except for filings under the HSR Act and under the
Securities Act and the Exchange Act, no authorization, approval or consent of,
or filing with, any court or governmental authority or agency, or under the
certificate of incorporation of the Company, is necessary or required in
connection with the purchase of the Securities hereunder or the execution,
delivery or performance of this Agreement or the transactions contemplated
hereby.

     5.5 LUK's Investment Intention. LUK represents and warrants that it is
purchasing the Securities for its own account, for investment purposes and not
with a view to the distribution thereof, except in compliance with the
provisions of the Securities Act of 1933, as amended (the "Act"). LUK agrees
that it will not, directly or indirectly, offer, transfer, sell, assign, pledge,
hypothecate or otherwise dispose of any of the Securities (or solicit any offers
to buy, purchase, or otherwise acquire or take a pledge of any of the
Securities), except in compliance with the Act and the rules and regulations
thereunder.

     5.6 Access to Data. LUK has had an opportunity to discuss the Company's
business, management, and financial affairs with its management and to review
the Company's records and facilities, and LUK is relying for purposes of this
Agreement upon its own due diligence review of the Company, not on any
representation or warranty of the Company other than as expressly set forth in
this Agreement.

VI.  COVENANTS
     ---------

     6.1 Tax Compliance. The Company shall pay all transfer, excise or similar
taxes in connection with the issuance, sale, delivery or transfer by the Company
to LUK of the Securities and shall save LUK harmless without limitation as to
time against any and all liabilities with respect to such taxes. The obligations
of Company under this Section 6.1 shall survive the payment, prepayment or
redemption of the Securities and the termination of this Agreement.

     6.2 Registration Rights. At any time after the date hereof, upon the
written request of LUK that the Company effect the registration under the Act
(which shall be a shelf registration if requested by LUK) of all or part of the
shares of Common Stock (including the Securities upon their issuance) owned by
LUK (including any affiliate of LUK) and specifying the intended method or
methods of disposition thereof, the Company shall, at its own cost, cooperate
with LUK and effect the registration under the Act of such shares as soon as
practicable after receipt of such request.

                                 PROMISSORY NOTE



$15,806,723                                                   New York, New York
                                                              September 1, 1999

          FOR VALUE RECEIVED, the undersigned, MK Gold Company, a Delaware
corporation with offices at 60 East South Temple, Salt Lake City, Utah 84111
(the "Maker"), hereby promises to pay to Leucadia National Corporation, a New
York corporation (the "Payee"), at its offices located at 315 Park Avenue South,
New York, New York 10010, or at such other place as Payee or any holder hereof
may from time to time designate to Maker in writing, the principal sum of
$15,806,723 on September 1, 2001 (the "Maturity Date"). Maker promises to pay
interest in lawful money of the United States on the unpaid principal amount of
this Note from the date hereof until such principal amount is paid in full, at
the interest rate specified in the next sentence. Interest shall accrue on the
unpaid principal balance hereof at an annual rate of 8% per annum for a period
of 60 days from the date hereof, and thereafter at the annual rate of 12% per
annum until payment of this Note in full. Interest hereunder shall be payable
semi-annually in arrears on the last day of September and March, beginning on
March 31, 2000 and on the Maturity Date and shall be computed on the basis of
the actual number of days elapsed over the period of a 360-day year. On any day
on which the Maker is to pay any amount due under this Promissory Note ("Payment
Day"), funds must be received at or before 11:00am New York time. Funds received
after 11:00am on any Payment Day will be treated as having been received on the
next day banks are open for business in New York.

          The following shall constitute Events of Default under this Note:

          (a) failure by Maker to make any payment of interest required under
this Note and such failure remains unremedied for 5 days;

          (b) failure by Maker to make any payment of the principal of this Note
when the same becomes due and payable at maturity, by acceleration or otherwise;

          (c) Maker pursuant to or within the meaning of any bankruptcy law:

          (i) commences a voluntary case; (ii) consents to the entry of an order
for relief against him in an involuntary case; (iii) consents to the appointment
of a custodian for him or for all or substantially all of his property; (iv)
makes a general assignment for the benefit of his creditors; or (v) admits in
writing his inability generally to pay its debts as the same become due.

          Upon the occurrence of an Event of Default specified in clause (c)
above, the principal amount of this Promissory Note, together with all accrued
and unpaid interest thereon and all other amounts owing hereunder, shall become
immediately due and payable, without presentment, demand, notice, protest or
other requirements of any

<PAGE>
kind (all of which are hereby expressly waived by maker). If any other Event of
Default occurs and is continuing, then and in every such case, Payee, by notice
to Maker, may declare the unpaid principal of, and any accrued but unpaid
interest on, this Note to be due and payable. Upon such declaration, the
principal and interest on this Note shall be due and payable immediately.

          Maker hereby waives diligence, demand, presentment, protest and
(except as herein provided) notice, and assents to extensions of time of
payments, releases, surrender or forbearance or other indulgence, without
notice.

          Maker acknowledges and agrees that Maker's obligation to pay principal
and interest hereunder shall not be subject to any counterclaims, offsets or
defenses against Payee or any holder of this Note that are presently existing or
which may arise in the future.

          If this Note is referred to an attorney or other person for
collection, Maker shall be liable for the reasonable fees and expenses of such
attorney or person and the other reasonable expenses and costs of collection.

          No failure or delay on the part of Payee to exercise any right, power
or privilege under this Promissory Note and no course or privilege or operate as
a waiver of any default or an acquiescence therein, nor shall any single or
partial exercise of any such right, power or privilege preclude any other right,
power or privilege. The rights and remedies expressly provided for in this Note
are cumulative to, and not exclusive of, any rights or remedies that Payee
otherwise would have.

          THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAW OF THE STATE OF NEW YORK AND SHALL BE BINDING UPON THE SUCCESSORS AND
ASSIGNS OF MAKER AND SHALL INURE TO THE BENEFIT OF PAYEE, ITS SUCCESSORS,
ENDORSEES AND ASSIGNS.

          Nothing contained in this Note shall be deemed to establish or require
the payment of a rate of interest in excess of the maximum rate legally
enforceable. If the rate of interest called for under this Note at any time
exceeds the maximum rate legally enforceable, the rate of interest required to
be paid hereunder shall be automatically reduced to the maximum rate legally
enforceable. If such interest rate is so reduced and thereafter the maximum rate
legally enforceable is increased, the rate of interest required to be paid
hereunder shall be automatically increased to the maximum rate legally
enforceable, which in no event shall exceed the rate otherwise provided for in
this Note.

          Maker hereby irrevocably consents to the jurisdiction of the Courts of
the State of New York and of any Federal Court located in such State in
connection with any action or proceeding arising out of or relating to this
Note. Maker further agrees that Maker will not commence or move to transfer any
action or proceeding, arising out or relating to the provisions of this Note, in
any Court other than one located in the State of New York. In any such
litigation, Maker waives personal service of any summons,

                                       2
<PAGE>
complaint or other process and agrees that the service thereof may be made by
certified mail directed to Maker at the address set forth above or at such other
place as Maker may from time to time designate to Payee in writing.

          This Note may not be changed, modified or terminated orally, but only
by an agreement in writing signed by Maker and Payee.

          At any time and from time to time the holder of this Note, subject to
compliance with applicable securities laws, may transfer this Note and assign
its rights hereunder pursuant to a written instrument of transfer duly executed
by the holder of this Note or its attorney duly authorized in writing.

          If any term or provision of this Note shall be held invalid, illegal
or unenforceable, the validity of all other terms and provisions hereof shall in
no way be affected.

     THIS OPTION AGREEMENT ("Agreement") is entered as of the 26th day of
August, 1999 (the "Effective Date"), by MK Gold Company, a Delaware corporation
("MKG"), the address of which is 60 E. South Temple, Salt Lake City, Utah 84111
and Straits Resources Limited, an Australian Corporation ("SRL"), (ACN # 056 601

follows:


                                    RECITALS

     MKG and SRL are parties to that certain Heads of Agreement, executed on
July 19, 1999 relating to a possible joint bid by MKG and SRL to acquire Riomin

Rio Tinto plc ("Rio Tinto"), and its 100% owned Las Cruces Project and its
associated Exploration Package I located near Seville, Spain (the "Project") and
Exploration Package II.

     MKG and SRL now desire that MKG shall acquire the Project in accordance
with the agreed bid consideration, subject to SRL's right to receive an option
to purchase 35% interest in the Project in accordance with the terms and subject
to the conditions of this Agreement.


                                   ARTICLE I
                                  DEFINITIONS

     2.1 Option. MKG hereby grants to SRL, or its affiliate, the irrevocable,
exclusive, and non-transferable option ("Option") to purchase an unencumbered
35% interest in Riomin Exploraciones, SA as 100% owners of the Project and

     2.2 Exercise Period. The Option may be exercised at any time during the
period commencing on the date that MKG acquires the Project ("Acquisition Date")
and ending on the date exactly twelve months from the Acquisition Date (the

     2.3 Time and Manner of Exercise. In order to exercise the Option, SRL shall
provide written notice to MKG of its intent to exercise the Option specifying
the proposed closing date for the exercise of the Option (the "Option Closing

within the Option Period.

     2.4 Purchase Price. The price for the purchase of the Option shall be an
amount equal to (i) 35% of MKG's initial up-front payment to Rio Tinto and
direct Project expenditures post acquisition from the date of acquisition to the

Purchase Price on the Option Closing Date by wire transfer of immediately
available funds to an account specified in writing by MKG.

feasibility study. MKG agrees to utilize SRL technical expertise to develop the
project as an open pit SX-EW operation in a mutually agreeable manner.

     2.7 Termination. If SRL does not timely exercise the Option within the
Option Period, this Agreement shall expire and be of no further force and
effect; provided, however, that the interest acquired by SRL under Section 5.1
shall survive a termination of this Agreement under this Section 2.7.

                                  ARTICLE III

     4.1 Representations and Warranties of Both Parties. Each Party warrants and

this

                                       2
<PAGE>
Agreement and all transactions contemplated herein and that all corporate, board

                                   ARTICLE V
                           FAILURE TO EXERCISE OPTION

     5.1 SRL's Failure to Exercise Option. If, and only if, MKG acquires the
Project and SRL does not elect to exercise the Option, SRL shall receive, in
lieu of any other compensation, US$2 Million to be paid upon the earlier of the
commencement of commercial production of the Las Cruces Project or the transfer
by MKG of its beneficial interest in the Project other than to an entity that
remains an affiliate of MKG.

                                   ARTICLE VI
                          RIGHT TO TERMINATE RELATIONS

     6.1 Right to Terminate Relations. If MKG has not acquired the Project
within six (6) months from the Effective Date of this Agreement and if at that
time no negotiations by MKG are ongoing for acquisition of the Project, the
Parties' obligations under this Agreement, and any further relations or
obligations between the Parties shall cease to exist, at the option of either
Party.

                                  ARTICLE VII
                            OPERATION OF THE PROJECT

     If SRL timely exercises the Option and pays the Purchase Price to MKG, the
Parties will jointly operate the Project and the interests in Exploration
Package II, pursuant to the following general terms and conditions:

     7.1 Business Entity. The Parties will acquire and hold their interests in
the Project through a corporation or other business entity or arrangement (the
"Company") unless they otherwise mutually agree.

     7.2 Definitive Agreement. If SRL timely exercises the Option and pays the
Purchase Price to MKG, the Parties will diligently and in good faith negotiate
and execute one or more definitive agreements setting forth their rights and
obligations in respect of the Project and Exploration Package II and the
Company, which agreement or agreements shall contain the terms and conditions
set forth in this Article VII, together with other terms and conditions as are
customary in the mining industry.

     7.3 Initial Ownership Interests. After such time that SRL has exercised the
Option and paid the Purchase Price to MKG, the Parties shall have the following
initial ownership interest in the Project ("Ownership Interests"):

                                        3
<PAGE>
          MKG - 65%
          SRL - 35%

     7.4 Additional Contributions. After SRL's payment of the Purchase Price,
each Party shall be obligated to contribute its pro rata share, based on its
current Ownership Interest, of all approved costs incurred by or for the
Project.

     7.5 Adjustment of Ownership Interests. If either Party contributes less
than its pro-rata share of anticipated Project costs, its Ownership Interest
will be proportionately reduced as follows: the reduced Party's Ownership
Interest shall be recalculated by dividing: (X) the sum of (1) the value of the
reduced Party's initial contribution (for SRL- the Purchase Price and for MKG-
total expenditures for the purchase and operation of the project to the Option
Closing Date minus the Purchase Price), (2) the total of all of the reduced
Party's contributions under Section 7.4, and (3) the amount, if any, the reduced
Party contributed to the Project with respect to which the default occurred; by
(Y) the sum of (1), (2) and (3) above for both Parties; and then multiplying the
result by one hundred. The Participating Interest of the other Party shall be
increased by the amount of the reduction in the Ownership Interest of the
reduced Party. A reduced Party whose recalculated Participating Interest becomes
less than ten percent (10%) shall relinquish its entire Ownership Interest to
the other Party and the reduced Participant shall have the right to receive a
ten percent (10%) Net Profits Interest.

     7.6 Project Management. The Project will be managed by a committee or board
("Management Committee") to determine overall policies, objectives, procedures,
methods and actions of the Company. The Management Committee shall consist of
two (2) members appointed by MKG and two (2) members appointed by SRL. MKG shall
designate one of its members to serve as the chair of the Management Committee.

     7.7 Decisions. Each Party, acting through its appointed member(s) in
attendance at the meeting, shall have the votes on the Management Committee in
proportion to its Ownership Interest. Unless otherwise provided, the vote of the
Party with an Ownership Interest over fifty percent (50%) shall determine the
decisions of the Management Committee. All matters coming before the Management
Committee will be decided by simple majority vote; provided, however, that the
following matters shall require unanimous consent: the approval of annual
programs and budgets (a procedure to break a deadlock with regard to annual
programs and budgets will be contained in the joint venture agreement to be
completed by the Parties), matters regarding the sale of all or a material part
of the Project, the incurring of debt over US$ 5 million for any particular item
by the Company, a significant change of scope for development of the Project as
described by the Feasibility Study, or the entering into by the Joint Venture
Company of any single contract during Mining Operations the value of which
exceeds US$5 million.

     7.8 Feasibility Study. At such time as either Party is of the good faith
and reasonable opinion that economically viable Mining Operations may be
possible on the

                                       4
<PAGE>
Project, the Party may propose to the Management Committee that a Feasibility
Study be prepared.

     7.9 Project Financing. If the Management Committee determines to develop a
mine at the Project, the Parties will cooperate in seeking to obtain limited
recourse financing for mine construction and development; provided, however,
that each Party will be responsible solely for its own share of any project
financing.

     7.10 Transfer of Interest. A Party shall have the right to transfer to a
third party an interest in its Ownership Interest; provided, however that (a)
neither Party shall transfer all or any part of a Party's Ownership Interest
without the consent of the other Party which shall not be unreasonably withheld;
(b) neither Party shall transfer all or any part of its Ownership Interest
without affording the other Party a right of first refusal with respect to the
proposed transfer; and (c) no transferee of all or any part of a Party's
Ownership Interest shall have the rights of a Party unless and until the
transferring Party has provided to the other Party notice of the transfer, and,
the transferee, as of the effective date of the transfer, has committed in
writing to assume and be bound the same extent as the transferring Party. This
Section 7.10(a) and (b) shall not apply to a transfer resulting from the sale of
all or substantially all of the assets of either Party or the merger or
corporate reorganization of either Party, or to a transfer to a wholly-owned
subsidiary or Affiliate of either Party.

     7.11 Exploration Package II. If SRL timely exercises the Option and pays
the Purchase Price, SRL shall have an initial ownership interest in Exploration
Package II equal to 35% of MKG's interest in Exploration Package II existing at
the time of exercise. The provisions of Article VII shall apply to the parties'
interests in Exploration Package II mutatis mutandis, it being the intention of
the parties that, so long as no adjustment of ownership interests occurs (as
between MKG and SRL) under the provisions of clause 7.5 hereof, MKG shall have a
65% interest and SRL shall have a 35% interest in whatever rights to Exploration
Package II that MKG would have otherwise possessed if the Option had not been
timely exercised and paid for. In the event of an adjustment under clause 7.5
hereof, the provisions of clause 7.5 shall determine the relative interests of
the parties in Exploration Package II.

                                  ARTICLE VIII
                               GENERAL PROVISIONS

     8.1 Notices. All notices, payments and other required or permitted

                           STRAITS RESOURCES LIMITED

                        NET PROFITS INTEREST CALCULATION
                        --------------------------------

9.1 Income and Expenses. Net Profits Interest shall be calculated by deducting
from the Gross Revenue (as defined below) realized, such costs and expenses
attributable to Exploration, Development, Mining, the marketing of Products and
other Operations as would be deductible under generally accepted accounting
principles and practices consistently applied, including without limitation:

          (a) All costs and expenses of replacing, expanding, modifying,
altering or changing from time to time the Mining facilities. Costs and expenses
of improvements (such as haulage ways or mill facilities) that are also used in
connection with workings other than the Project shall be charged to the Project
only in the proportion that their use in connection with the Project bears to
their total use;

          (b) Ad valorem real property and unsecured personal property taxes,
and all taxes, other than income taxes, applicable to Mining of the Project,
including without limitation all state mining taxes, sales taxes, severance
taxes, license fees and governmental levies of a similar nature;

          (c) Allowance for project overhead;

          (d) All expenses incurred relative to the sale of Products, including
an allowance for commissions at rates which are normal and customary in the
industry;

          (e) All amounts payable to the remaining Party during Mining pursuant
to any applicable operating or similar agreement in force with respect thereto;

          (f) The actual cost of investment under the Agreement but prior to
beginning of Mining, which shall include all expenditures for Exploration and
Development of the Project incurred by the non-withdrawing Party both prior and
subsequent to the withdrawing Party acquiring a Net Profits Interest;

                                 Exhibit B - 1
<PAGE>
          (g) Interest on monies borrowed or advanced for costs and expenses,
but in no event in excess of the maximum permitted by law (interest on equity
contributions will not be included);

          (h) An allowance for reasonable working capital and inventory;

          (i) Costs of funding Environmental Compliance;

          (j) Actual costs of Operations; and

          (k) Rental, royalty, production, and purchase payments.

     For purposes hereof, the term "Gross Revenue" shall mean the sum of (i)
gross receipts from sale of Products, less any charges for sampling, assaying,
or penalties; (ii) gross receipts from the sale or other disposition of Assets;
(iii) insurance proceeds; (iv) compensation for expropriation of Assets; and (v)
judgment proceeds.

     It is intended that the remaining Party shall recoup from Gross Revenue all
of its on-going contributions for Exploration, Development, Mining, Expansion
and Modification and marketing Products before any Net Profits Interest are
distributed to any person holding a Net Profits Interest. It is the intention of
the parties that in calculating such Net Profits, the remaining party shall be
entitled to recover capital expenditures by depreciating such expenditures over
the life of the Project. If in any year after the beginning of Mining of the
Project an operating loss relative thereto is incurred, the amount thereof shall
be considered as and be included with outstanding costs and expenses and carried
forward in determining Net Profits Interest for subsequent periods. If Products
are processed by the remaining Party, or are sold to an Affiliate of the
remaining Party, then, for purposes of calculating Net Profits Interest, such
Products shall be deemed conclusively to have been sold at a price equal to fair
market value to an arm's length purchaser FOB the concentrator for the Project,
and Net Profits Interest relative thereto shall be calculated without reference
to any profits or losses attributable to smelting or refining.

     9.2 Payment of Net Profits Interest. Payments of Net Profits Interest shall
commence in the calendar quarter following the calendar quarter in which Net
Profits Interest are first realized, and shall be made forty-five (45) days
following the end of each calendar quarter during which Net Profits Interest are
realized, and shall be subject to adjustment, if required, at the end of each
calendar year. The recipient of such Net Profits Interest payments shall have
the right to audit such payments following receipt of each payment by giving
notice to the remaining Party and by conducting such audit in accordance with
the terms agreed to by the Parties. Costs of such an audit shall be borne by the
holder of the Net Profits Interest described herein.

     9.3 Definitions. All capitalized words and terms used herein have the same
meaning as in the Agreement.
