Amendment No. 4 to Schedule 13D This Amendment No. 4 to Schedule 13D (this "Amendment") is filed by the Reporting Persons as an amendment to the initial statement on Schedule 13D as filed with the Securities and Exchange Commission on December 8, 2003 (the "Original Schedule 13D"), as amended by Amendment No. 1 to Schedule 13D filed with the Securities and Exchange Commission on December 15, 2003 (the "First Amendment"), as further amended by Amendment No. 2 to Schedule 13D filed with the Securities and Exchange Commission on January 9, 2004 (the "Second Amendment") as further amended by Amendment No. 3 to Schedule 13D filed with the Securities and Exchange Commission on March 31, 2004 (the "Third Amendment", and together with the Original Schedule 13D, the First Amendment, the Second Amendment and the Third Amendment the "Schedule 13D"). Capitalized terms used but not defined in this Amendment have the meanings set forth in the Schedule 13D. The Schedule 13D is hereby amended and supplemented as follows: ITEM 2. IDENTITY AND BACKGROUND Item 2 of the Schedule 13D is hereby amended to report that Gold Fields Mining Corporation, a Delaware corporation, converted into a Delaware limited liability company with the name Gold Fields Mining, LLC. All references to Gold Fields in the Schedule 13D now refer to Gold Fields Mining, LLC, a Delaware limited liability company. Item 2 of the Schedule 13D also is hereby amended to replace Appendix A to the First Amendment with Appendix A to this Amendment. Appendix A to this Amendment includes, as of the date of this Amendment, the name, state of incorporation or organization, principal business, and principal place of business of each general partner of PNRC. Appendix A also includes, as of the date of this Amendment, the names, residence or business addresses, citizenship and present principal occupations or employment of the executive officers and directors of (1) Parent, (2) Gold Fields and (3) each other general partner of PNRC. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Item 5 of the Schedule 13D is hereby amended to read in its entirety as follows: (a) Based on the information reported by Issuer in its Quarterly Report on Form 10-Q for the quarter ended September 30, 2004, there were 10,424,681 Common Units outstanding as of November 1, 2004. As of December 30, 2004, PNRC owns 836,851 Common Units, representing 8.0% of the outstanding Common Units of Issuer, based on the number of Common Units outstanding as of November 1, 2004. As of December 30, 2004, Gold Fields may be deemed to beneficially own, by virtue of its ownership of PNRC, the same 836,851 Common Units, representing 8.0% of the outstanding Common Units of Issuer, based on the number of Common Units outstanding as of November 1, 2004. As of December 30, 2004, Parent may be deemed to beneficially own, by virtue of its ownership of PNRC and Gold Fields, the same 836,851 Common Units, representing 8.0% of the outstanding Common Units of Issuer, based on the number of Common Units outstanding as of November 1, 2004. In connection with the foregoing acquisition of Common Units by PNRC, Issuer placed 52,700 Common Units in escrow pending transfer to Issuer of certain coal mineral estates in certain parcels and tracts of land. On March 24, 2004, PNRC received 51,393 of these Common Units from the escrow following the transfer of some of the coal mineral estates to the Issuer, and now only 1,307 Common Units remain in escrow. The remaining 1,307 Common Units held in escrow are registered in the name of U.S. Bank National Association, as escrow agent. If the remaining coal mineral estates are transferred to Issuer prior to the deadline in the escrow agreement, the remaining 1,307 Common Units will be released from escrow to PNRC. (b) PNRC has sole power to vote or direct the vote and to dispose or to direct the disposition of the Common Units beneficially owned by it. Gold Fields, by virtue of its ownership of PNRC, may be deemed to have the power to vote or direct the vote and to dispose or to direct the disposition of the Common Units beneficially owned by PNRC. Parent, by virtue of its ownership of PNRC and Gold Fields, may be deemed to have the power to vote or direct the vote and to dispose or to direct the disposition of the Common Units beneficially owned by PNRC. (c) PNRC completed the sale of 200,000 Common Units on December 30, 2004 with net proceeds to PNRC of $50.27 per unit. The sale was made in compliance with Rule 144 of the Securities Act of 1933. Except for that sale, no transactions in Common Units were effected by the Reporting Persons, or to their knowledge, any of the persons listed on Appendix A to the Schedule 13D since the filing of the Third Amendment. (d) No person is known by any Reporting Person to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any Common Units owned by any Reporting Person. (e) Not applicable.
