SUMMARY

This summary highlights information contained elsewhere in this proxy statement/prospectus and may not contain all the information that is important to you. MMR urges you to read carefully the remainder of this proxy statement/prospectus, including the attached annexes, and the other documents to which MMR has referred you because this section does not provide all the information that might be important to you with respect to the charter amendment and merger being considered at the MMR special meeting. See also the section entitled “Where You Can Find More Information” beginning on page 160. MMR has included page references to direct you to a more complete description of the topics presented in this summary.

Special Factors (see page 24)

General Description and Effects of the Merger (see page 24)

At the effective time, Merger Sub will merge with and into MMR, with MMR surviving the merger as a wholly owned subsidiary of FCX.

Pursuant to the merger agreement, at the effective time, each issued and outstanding share of MMR common stock, other than any dissenting shares or shares held by FCX and any of its subsidiaries (including any shares acquired in connection with the consummation of the transactions contemplated by the PXP merger agreement), will be converted into the right to receive $14.75 in cash and 1.15 royalty trust units, which is referred to herein as the merger consideration. As of the date of this proxy statement/prospectus, none of the subject interests associated with the royalty trust units had any reserves classified as proved, probable or possible, other than MMR’s onshore Lineham Creek well, and none of such subject interests had any associated production. Cash will be paid in lieu of any fractional royalty trust units. Pursuant to the merger agreement, equity awards relating to shares of MMR common stock will either be cancelled and converted upon the consummation of the merger into the right to receive the merger consideration or will be converted into comparable equity awards relating to FCX common stock on generally the same terms and conditions as prior to the merger. Concurrently with the execution of the merger agreement, certain executive officers of MMR waived their contractual rights to accelerated vesting of equity awards as a result of the merger. For additional information on equity awards relating to shares of MMR, see the section entitled “Special Factors—Treatment of Options and Restricted Stock Units” beginning on page 92.

The corporate headquarters of the combined company will be located in Phoenix, Arizona, and the combined company expects to maintain offices in Houston, Texas and New Orleans, Louisiana, to support its oil and gas operations and existing administrative functions. FCX and MMR expect to complete the merger in the second quarter of 2013. However, the merger is subject to approvals and other conditions, and it is possible that factors outside the control of MMR and FCX could result in the merger being completed at a later time, or not at all.

MMR’s Reasons for the Merger and Recommendation of the MMR Special Committee and Board of Directors (see page 39)

The MMR special committee has unanimously (i) determined that the charter amendment and merger are fair to, advisable and in the best interests of MMR and its stockholders; (ii) approved the merger agreement; and (iii) recommended that the MMR board of directors adopt and approve the merger agreement.

Acting upon the unanimous recommendation of the MMR special committee, the MMR board of directors has approved the charter amendment and the merger agreement and recommends that MMR stockholders vote to approve the charter amendment and adopt the merger agreement.

Subject to certain conditions, the MMR board of directors, acting upon the recommendation of the MMR special committee, may change its recommendation in response to either (i) an intervening event or (ii) a superior proposal, if it determines, after consultation with its outside financial advisors and outside counsel, that not doing so would be inconsistent with its fiduciary duties under applicable law.

Opinion of Financial Advisor to the MMR Special Committee (see page 56)

In connection with the merger, on July 16, 2012, the MMR special committee retained Evercore Group L.L.C., which is referred to herein as Evercore, to act as a financial advisor to the MMR special committee. On December 5, 2012, at a meeting of the MMR special committee, Evercore rendered its oral opinion, subsequently confirmed by delivery of a written opinion later that day, that, as of December 5, 2012 and based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, the merger consideration to be received by the holders of shares of MMR common stock pursuant to the merger agreement was fair, from a financial point of view, to the holders of shares of MMR common stock entitled to receive such merger consideration (other than PXP or any of its subsidiaries).

The full text of the written opinion of Evercore, dated as of December 5, 2012, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is attached as Annex C to this proxy statement/prospectus and is incorporated by reference in its entirety into this proxy statement/prospectus. You are urged to read the opinion carefully and in its entirety. Evercore’s opinion was addressed to, and provided for the information and benefit of, the MMR special committee (in its capacity as such) in connection with its evaluation of whether the merger consideration to be received by the holders of shares of MMR common stock was fair, from a financial point of view, to the holders of shares of MMR common stock entitled to receive such merger consideration (other than PXP or any of its subsidiaries) and did not address any other aspects or implications of the merger. Evercore’s opinion does not address the fairness of the proposed merger, or any consideration received in connection with the proposed merger, to the holders of any other securities, creditors or other constituencies of MMR, nor does it address the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of MMR, or any class of such persons, whether relative to the merger consideration or otherwise. Evercore assumed that any modification to the structure of the merger would not vary in any respect material to its analysis. Evercore’s opinion does not address the relative merits of the merger as compared to any other business or financial strategies that might be available to MMR, nor does it address the underlying business decision of MMR to engage in the merger. Evercore’s opinion does not constitute a recommendation to the MMR special committee or to any other persons in respect of the merger, including as to how any holder of shares of common stock of MMR should act or vote in respect of the merger. Finally, Evercore did not express any opinion as to the price at which shares of MMR capital stock or shares of FCX capital stock will trade at any time or as to the price at which the royalty trust units will trade at any time.

Opinion of Financial Advisor to the FCX Special Committee (see page 68)

On December 4, 2012, Credit Suisse Securities (USA) LLC, which is referred to herein as Credit Suisse, rendered its oral opinion to the special committee of the FCX board of directors (which was subsequently confirmed in writing by delivery of Credit Suisse’s written opinion dated the same date) with respect to the fairness, from a financial point of view, to FCX of the aggregate merger consideration (which, for purposes of the opinion, refers to the aggregate cash consideration and royalty trust units) to be paid or issued by FCX for the outstanding shares of MMR common stock in the merger pursuant to the merger agreement.

Credit Suisse’s opinion was directed to the FCX special committee (in its capacity as such), and only addressed the fairness, from a financial point of view, to FCX of the aggregate merger consideration to be

paid or issued by FCX in the merger pursuant to the merger agreement and did not address any other aspect or implication of the merger, including, without limitation, the fairness from a financial point of view to MMR’s stockholders of the merger consideration to be received by MMR’s stockholders in the merger pursuant to the merger agreement. The Credit Suisse opinion did not address the fairness to the holders of MMR common stock (in their capacity as such) of the merger or the merger consideration to be received by such holders in the merger or the differing interests of such holders, discussed under “Differing Interests of MMR Stockholders and FCX.” This proxy statement/prospectus includes a summary of Credit Suisse’s opinion and the material financial analyses performed by Credit Suisse in connection with the preparation of its opinion. The full text of Credit Suisse’s written opinion is included as an exhibit to the Rule 13e-3 transaction statement on Schedule 13E-3 with respect to the merger filed with the SEC as of the date hereof, which is referred to herein as the Schedule 13E-3, and is incorporated by reference hereby and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Credit Suisse in preparing its opinion. However, neither Credit Suisse’s written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement/prospectus are intended to be, and they do not constitute a recommendation to the FCX special committee or the FCX board of directors with respect to the proposed merger or advice or a recommendation to any holder of MMR common stock as to how such holder should vote or act on any matter relating to the proposed merger. See the section entitled “Special Factors—Opinion of Financial Advisor to the FCX Special Committee” beginning on page 68.

Differing Interests of MMR Stockholders and FCX in the Merger (see page 50)

The interests of MMR stockholders other than FCX with respect to the merger consideration are significantly different from the interests of FCX. Among other things, FCX will pay the merger consideration in exchange for all of the outstanding equity interests in MMR while MMR stockholders other than FCX will receive the merger consideration in exchange for their equity interests in MMR and, following the consummation of the merger, MMR stockholders will not have a direct or indirect equity ownership interest in MMR or any of its assets. However, the royalty trust units that MMR stockholders receive as merger consideration pursuant to the merger agreement will provide the right to have an economic interest with respect to MMR’s ultra-deep assets.

Interests of MMR Directors and Executive Officers in the Merger (see page 76)

In considering the recommendation of the MMR board of directors, acting upon the unanimous recommendation of the MMR special committee, to adopt the merger agreement, MMR stockholders should be aware that certain MMR executive officers and directors may be deemed to have interests in the merger that are different from, or in addition to, those of MMR stockholders generally. These interests, which may create actual or potential conflicts of interest, are, to the extent material, described in the section entitled “Special Factors—Interests of MMR Directors and Executive Officers in the Merger” beginning on page 76. The MMR board of directors was aware of these potential conflicts of interest and considered them, among other matters, in evaluating and negotiating the merger agreement, in reaching its decision to approve the merger agreement, and in recommending to MMR stockholders that the merger agreement be adopted. These interests include the following:

In addition, certain MMR directors and executive officers own significant amounts of MMR common stock, as described in the section entitled “Stock Ownership of FCX and MMR Directors and Executive Officers and Certain Beneficial Owners—Ownership of MMR Directors and Executive Officers” beginning on page 142. Shares of MMR common stock held by MMR directors and executive officers will be treated in the merger in the same manner as shares held by unaffiliated holders. Assuming the merger was consummated on April 26, 2013, the merger consideration payable to the MMR directors in the aggregate would consist of approximately $134.9 million in cash and 10.5 million royalty trust units. See the section entitled “Special Factors—Interests of MMR Directors and Executive Officers in the Merger—Merger Consideration Payable to MMR Directors” beginning on page 78.

Interests of the FCX Parties in the Merger (see page 154)

In considering voting on the proposals to be presented at the special meeting and other matters related to the merger, MMR stockholders should be aware that FCX has interests in the merger that are different from, or in addition to, those of MMR stockholders generally. These interests, which may create actual or potential conflicts of interest, are, to the extent material, described in the section entitled “Related Party Transactions” beginning on page 154. The MMR board of directors and the special committee of the MMR board of directors were aware of these potential conflicts of interest and considered them, among other matters, in evaluating and negotiating the merger agreement, in reaching its decision to approve the merger agreement, and in recommending to MMR stockholders that the merger agreement be adopted. These interests include the following:

In addition, on December 5, 2012, FCX entered into the PXP merger agreement, pursuant to which FCX agreed to acquire PXP. The PXP merger is a separate transaction and the completion of the PXP merger is not a condition to the completion of the merger, nor is completion of the merger a condition to the completion of the PXP merger. PXP is the owner of shares of MMR common stock representing approximately 31.3% of the outstanding shares of MMR common stock as of April 4, 2013, the record date, and PXP has entered into a support agreement with respect to the merger, which generally obligates PXP, in its capacity as a stockholder of MMR, to vote all of its shares of MMR common stock in favor of the charter amendment proposal and the merger proposal and against alternative transactions and generally prohibits PXP from transferring its shares of MMR common stock prior to the consummation of the merger.

For a discussion of certain relationships between MMR and FCX, see the section entitled “Related Party Transactions” beginning on page 154.

Material U.S. Federal Income Tax Consequences of the Merger (see page 80)

The MMR stockholders’ receipt of the merger consideration in exchange for their shares of MMR common stock in the merger will be a fully taxable transaction for U.S. federal income tax purposes.

The Royalty Trust intends to treat itself as a grantor trust. Accordingly, the Royalty Trust unitholders will be taxed directly on their pro-rata share of the income attributable to the assets of the Royalty Trust. The U.S. federal

income tax treatment of the royalty interests held by the Royalty Trust is subject to uncertainty. Based on the state of facts as of the date hereof, however, the Royalty Trust intends to treat the royalty interests as mineral royalty interests for U.S. federal income tax purposes, generating ordinary income subject to depletion. If the royalty interests are not properly treated as mineral royalty interests, then the royalty interests would be treated as a debt instrument for U.S. federal income tax purposes and a Royalty Trust unitholder, in that event, will be required to include in such Royalty Trust unitholder’s income its share of the interest income on such debt instrument as it accrues in accordance with the rules applicable to contingent payment debt instruments contained in the Internal Revenue Code of 1986, as amended, and the corresponding regulations. In such a case, the amount, timing and character of income, gain, or loss in respect of an investment in the Royalty Trust could be affected.

For more information, see the section entitled “Special Factors—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 80.

MMR URGES YOU TO CONSULT YOUR OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO YOU OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES.

Before deciding whether to vote for the proposals presented in this proxy statement/prospectus, you should carefully consider all of the information contained in or incorporated by reference herein, as well as the specific material U.S. federal income tax consequences under the section entitled “Special Factors—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 80.

Regulatory Approvals Required for the Merger (see page 91)

To complete the merger, FCX and MMR must make filings with antitrust authorities in the United States and obtain the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the related rules and regulations, which is referred to herein as the HSR Act, which provide that certain transactions may not be completed until required information has been furnished to the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission and until certain waiting periods have been terminated or have expired. MMR and FCX each filed a notification and report form with the Antitrust Division and the FTC on December 14, 2012. Early termination of the HSR waiting period was granted by the FTC on December 26, 2012.

FCX and MMR will seek to complete the merger in the second quarter of 2013.

Legal Proceedings (see page 96)

Purported MMR stockholders have filed a number of putative class actions challenging the merger on behalf of all MMR stockholders. In addition, purported FCX stockholders have filed a number of derivative actions challenging the merger on behalf of FCX. The defendants in these lawsuits include, among others, MMR, FCX, members of their boards of directors, the Royalty Trust, Merger Sub and PXP. The lawsuits seek various forms of relief, including an injunction barring or rescinding the merger and damages. Additional information on these legal proceedings related to the merger is provided in the section entitled “Special Factors—Legal Proceedings,” beginning on page 96. The MMR and FCX defendants believe the lawsuits are without merit and intend to defend vigorously against them.

Risk Factors (see page 99)

Before deciding whether to vote for the proposals presented in this proxy statement/prospectus, you should carefully consider all of the information contained in or incorporated by reference herein, as well as the section entitled “Risk Factors” beginning on page 99.

The Companies (see page 108)

MMR

McMoRan Exploration Co.

1615 Poydras Street

New Orleans, Louisiana 70112

(504) 582-4000

McMoRan Oil & Gas Co., the immediate predecessor of McMoRan Exploration Co. (MMR), was incorporated under the laws of the State of Delaware on April 15, 1994. On May 12, 1994, Freeport-McMoRan Inc. spun off its oil and gas operations to its shareholders through a distribution of shares of McMoRan Oil & Gas Co. At the time of the spin-off, James R. Moffett and Richard C. Adkerson were (1) Co-Chairman of the Board and Co-Chairman of the Board and Chief Executive Officer, respectively, of McMoRan Oil & Gas Co. and (2) Chairman of the Board and Senior Vice President, respectively, of Freeport-McMoRan Inc. Following its separation from Freeport-McMoRan Inc., McMoRan Oil & Gas Co. pursued a business plan of exploring for and producing oil and gas, primarily in the Gulf of Mexico and onshore in the Gulf Coast area. Freeport Sulphur Company was incorporated under the laws of the State of Delaware on August 26, 1997 (name was changed to Freeport-McMoRan Sulphur Inc. on October 21, 1997). MMR was incorporated under the laws of the State of Delaware on July 30, 1998. MMR began doing business as a publicly-traded company on November 17, 1998 when McMoRan Oil & Gas Co. and Freeport-McMoRan Sulphur Inc. combined their operations. As a result, McMoRan Oil & Gas LLC and Freeport-McMoRan Sulphur LLC (name was changed to Freeport-McMoRan Energy LLC on September 29, 2003), the successors to those companies, became MMR’s wholly owned subsidiaries.

MMR’s oil and gas operations are conducted through McMoRan Oil & Gas LLC, its principal operating subsidiary. MMR engages in the exploration, development and production of oil and natural gas in the shallow waters (less than 500 feet of water) of the Gulf of Mexico and onshore in the Gulf Coast area of the United States. MMR’s exploration strategy is focused on targeting large structures on the “deep gas play,” and on the “ultra-deep play.” Deep gas prospects target large deposits at depths typically between 15,000 and 25,000 feet. Ultra-deep prospects target objectives at depths typically below 25,000 feet. MMR has one of the largest acreage positions in the shallow waters of the Gulf of Mexico and Gulf Coast areas, MMR’s regions of focus. MMR has rights to approximately 855,000 gross acres, including approximately 381,000 gross acres associated with the ultra-deep gas play below the salt weld. MMR’s focused strategy enables it to make efficient use of its geological, engineering and operational expertise in these areas where MMR has more than 40 years of operating experience. MMR also believes that the scale of its operations in the Gulf of Mexico allows it to realize certain operating synergies and provides a strong platform from which to pursue its business strategy.

Royalty Trust

The Royalty Trust is a statutory trust created by FCX under the Delaware Statutory Trust Act pursuant to a trust agreement entered into on December 18, 2012, between FCX, as depositor, Wilmington Trust, National Association, as Delaware trustee and certain officers of FCX, as regular trustees. The Royalty Trust was created to hold certain overriding royalty interests, which are referred to herein as the royalty interests, in hydrocarbons saved and produced from MMR’s shallow water Gulf of Mexico and onshore Gulf Coast ultra-deep exploration

prospects, which are referred to herein as the subject interests. MMR owns less than 100% of the working interest in each of the subject interests.

Since 2008, MMR’s ultra-deep drilling activities (below the salt weld, i.e., the listric fault) have confirmed MMR’s geologic model and the highly prospective nature of this emerging geologic trend. Data from seven wells drilled to date tie geologic formations encountered below the salt weld to productive zones onshore, in the deepwater Gulf of Mexico and in Mexico. Each of these seven wells is included in the subject interests, along with additional exploration prospects that will also be burdened by the Royalty Trust. To date, only the Davy Jones No. 1 well has been completed and efforts continue to obtain a measurable flow rate. As such, the subject interests remain “exploration concepts” and further drilling and flow testing will be required to determine the commercial potential of the subject interests.

AT THIS TIME, THERE IS NO PRODUCTION AND THERE ARE NO RESERVES CLASSIFIED AS PROVED, PROBABLE OR POSSIBLE ASSOCIATED WITH THE SUBJECT INTERESTS, OTHER THAN THE LINEHAM CREEK WELL, OR THE ROYALTY TRUST UNITS. The Royalty Trust will have no ability to influence the exploration or development of the subject interests. In addition, FCX will be under no obligation to fund or to commit any other resources to the exploration or development of the subject interests.

FCX

Freeport-McMoRan Copper & Gold Inc.

333 North Central Avenue

Phoenix, Arizona 85004

(602) 366-8100

The merger agreement also provides that MMR is required to pay FCX a termination fee of $98 million if:

No Solicitation by MMR of Takeover Proposals (see page 117)

The merger agreement restricts the ability of MMR to, directly or indirectly:

If, however, at any time prior to the MMR stockholder approval having been obtained, MMR, directly or indirectly, receives a bona fide, unsolicited written takeover proposal from any person that does not result from a breach of the non-solicitation provisions of the merger agreement and if the MMR board of directors, acting upon the recommendation of the MMR special committee, determines in good faith, after consultation with its outside financial advisors and outside legal counsel, that such takeover proposal constitutes or would reasonably be expected to lead to a superior proposal, then MMR may directly or indirectly engage in or otherwise participate in discussions or negotiations with the person making such takeover proposal and its representatives and potential sources of financing regarding such takeover proposal.

The MMR Special Meeting (see page 132)

The special meeting of MMR stockholders is scheduled to be held at 10:00 a.m., local time, on Monday, June 3, 2013 at McMoRan Exploration Co., 1615 Poydras Street, New Orleans, Louisiana, 70112. At the MMR special meeting stockholders of MMR will be asked:

You may vote at the MMR special meeting if you owned common stock of MMR at the close of business on the record date, April 4, 2013.

You may cast one vote for each share of common stock of MMR that you owned on the record date.

Approval of the charter amendment proposal requires the affirmative vote of the holders of a majority of the outstanding shares of MMR common stock. Approval of the merger proposal requires the affirmative vote of holders of (1) a majority of the outstanding shares of MMR common stock and (2) a majority of the outstanding shares of MMR common stock, excluding shares owned by FCX and its subsidiaries, PXP and its subsidiaries, and certain MMR executive officers and directors who also serve as officers and/or directors of FCX, specifically, Richard C. Adkerson, Robert A. Day, Gerald J. Ford, H. Devon Graham, Jr., James R. Moffett, Nancy D. Parmelee, Kathleen L. Quirk and B. M. Rankin, Jr., who are referred to herein as the interested stockholders.
