Item 1.        Security and Issuer.
               -------------------

           This Statement constitutes Amendment No. 12 to the Statement on
Schedule 13D, as previously amended (the "Schedule 13D"), filed with the
Securities and Exchange Commission, by Leucadia National Corporation
("Leucadia") with respect to the shares of common stock, par value $0.01 per
share (the "Common Stock"), of MK Resources Company (formerly MK Gold Company)
("MK Resources"). Unless otherwise indicated, all capitalized terms used herein
shall have the meaning ascribed to them in the Schedule 13D.

Item 4.        Purpose of Transaction.
               ----------------------

           On August 8, 2005, MK Resources issued a press release (the "MK
Resources Press Release") announcing the declaration by the board of directors
of MK Resources of a dividend of one deferred valuation right (a "DVR") per
share on the Common Stock payable to all stockholders of record at the close of
business on August 18, 2005 (the "Record Date"). As stated in the MK Resources
Press Release, each DVR will entitle a stockholder of record on the Record Date
to receive an amount equal to its pro rata share of the proceeds, if any, after
deducting all expenses, from the orderly sale of the 4,821,905 common shares of
Bear Creek Mining Corporation ("Bear Creek") owned by MK Resources, after
deducting from such net sale proceeds $2,804,327 (the aggregate market value of
4,821,905 Bear Creek common shares at May 2, 2005, based on the closing sale
price for Bear Creek common shares on that date).

           On August 8, 2005, Leucadia consented to the declaration and payment
of the dividend of the DVR, and waived any breach by MK Resources of any of its
representations, warranties, covenants or agreements set forth in the Agreement
and Plan of Merger, dated as of May 2, 2005, among Leucadia, MK Resources and
Marigold Acquisition Corp. ("Merger Sub"), and the Credit Agreement, dated as of
March 1, 1998, as amended, between Leucadia and MK Resources, or any default
under those agreements that may result, directly or indirectly, as a result of
the declaration or payment of the dividend of the DVR.

           The MK Resources Press Release also announced MK Resources' agreement
to provide certain contractual appraisal rights to all record stockholders of MK
Resources who continuously hold shares of Common Stock through the effective
time of the proposed merger of Merger Sub, a wholly owned subsidiary of
Leucadia, with and into MK Resources pursuant to the Merger Agreement (the
"Merger").

           In connection with the proposed Merger, Leucadia has filed a
registration statement (File No. 333-125806) with the Securities and Exchange
Commission (the "SEC"). MK RESOURCES STOCKHOLDERS ARE URGED TO READ CAREFULLY
THE REGISTRATION STATEMENT, INCLUDING THE PROXY STATEMENT/PROSPECTUS INCLUDED
THEREIN, AND THE OTHER DOCUMENTS RELATING TO THE PROPOSED MERGER FILED WITH THE
SEC BECAUSE THEY CONTAIN IMPORTANT INFORMATION RELATING TO THE MERGER. Free
copies of these documents and other documents containing information about
Leucadia and MK Resources, may be obtained without charge, at the SEC's website
at www.sec.gov. Free copies of Leucadia's filings may also be obtained by
directing a request to Leucadia National Corporation, 315 Park Avenue South, New
York, New York 10010, Attention: Corporate Secretary, and free copies of MK
Resources' filings may also be obtained by directing a request to MK Resources
Company, 60 East South Temple, Suite 1225, Salt Lake City, Utah 84111,
Attention: Secretary.


                                       3

           Leucadia, MK Resources and their respective directors and executive
officers and other members of management and employees may be deemed to be
participants in the solicitation of proxies from stockholders of MK Resources in
respect of the proposed Merger. Information regarding Leucadia's directors and
executive officers is available in Leucadia's proxy statement for its 2005
annual meeting of stockholders, dated April 22, 2005, and information regarding
MK Resources' directors and executive officers is available in MK Resources'
Form 10-K/A for the fiscal year ended December 31, 2004, dated April 28, 2005.
Additional information regarding the interests of such potential participants is
included in the registration restatement, and the proxy statement/prospectus
included therein, and the other documents relating to the proposed Merger filed
with the SEC.
