James R. Moffett and Richard Adkerson, McMoRan?s Co-Chairmen, said, ?Our ultra-deep drilling program continues to confirm our geologic model which targets large structures in the shallow waters of the Gulf of Mexico that are analogous to the hydrocarbon bearing geologic formations seen onshore and in the deepwater. To date, each of the five exploratory wells drilled below the salt weld have confirmed the presence of hydrocarbon bearing sands. The results to date highlight the potential for multi-Tcfe reservoirs spanning a 200 square milearea on the Shelf of the Gulf of Mexico. We look forward to results from our ongoing drilling operations and the important flow test at Davy Jones, which would be the first production from this significant and emerging new geologic trend.?

PRODUCTION AND DEVELOPMENT ACTIVITIES

Third-quarter 2011 production averaged 187 MMcfe/d net to McMoRan, compared with 146
MMcfe/d in the third quarter of 2010. Production in the third quarter of 2011 was higher than McMoRan?s

2

previously reported estimates of 180 MMcfe/d in July 2011 because of favorable production performance. Production is expected to average approximately 170 MMcfe/d in the fourth quarter of 2011 and 187
MMcfe/d for the year. McMoRan?s estimated production rates are dependent on the timing of planned recompletions, production performance, weather and other factors.
Production from the Flatrock field averaged a gross rate of approximately 164 MMcfe/d (67
MMcfe/d net to McMoRan) in the third quarter of 2011, compared with 182 MMcfe/d (34 MMcfe/d net to McMoRan) in the third quarter of 2010. McMoRan owns a 55.0 percent working interest and a 41.3 percent net revenue interest in the Flatrock field.

EXPLORATION ACTIVITIES

McMoRan?s exploration strategy is focused in the shallow waters of the Gulf of Mexico (GOM) and
Gulf Coast area on the ?ultra-deep gas play? and on the ?deep gas play.?

Shallow Water, Ultra-Deep Exploration Update

Since 2008, McMoRan has actively pursued large ultra-deep targets located in the shallow waters of the GOM below the salt weld (i.e. listric fault) at depths generally below 25,000 feet. The data gained to date from five wells confirm McMoRan?s geologic model and the highly prospective nature of this emerging geologic trend. Prior to McMoRan?s involvement in the ultra-deep, there had been only two wells drilled on the Shelf targeting these objectives; one did not reach its targeted depth and the other was outside McMoRan?s focus area. McMoRan?s results to date have indicated the potential for large accumulations of hydrocarbons at these deeper depths in the shallow waters of the GOM.
McMoRan?s activities to date have confirmed that drilling below the salt weld on the Shelf of the GOM can be achieved safely. In addition, the data indicate the presence below the salt weld of geologic formations including Middle/Lower Miocene, Wilcox, Frio, Tuscaloosa and Cretaceous carbonate. These formations have been prolific onshore, in the deepwater GOM and in international locations. McMoRan is encouraged by the results which indicate the potential for prospects with high quality reservoirs on large structures with multi-Tcfe of gross unrisked potential. McMoRan intends to conduct further drilling and flow testing to determine the ultimate potential of this emerging geologic trend.
In September 2011, McMoRan commenced installation of production facilities on South Marsh Island Block 230 for the Davy Jones field. McMoRan is in the process of mobilizing a drilling rig to commence completion activities for the development of Wilcox sands in the Davy Jones discovery well (Davy Jones No.1) with flow testing expected by year-end 2011.
As previously reported, McMoRan has drilled two successful sub-salt wells in the Davy Jones field. The Davy Jones No.1 well logged 200 net feet of pay in multiple Wilcox sands, which were all full to base. The Davy Jones offset appraisal well (Davy Jones No. 2), which is located two and a half miles southwest of Davy Jones No. 1, confirmed 120 net feet of pay in multiple Wilcox sands, indicating continuity across the major structural features of the Davy Jones prospect, and also encountered 192 net feet of potential hydrocarbons in the Tuscaloosa and Lower Cretaceous carbonate sections. McMoRan has advanced the technology, equipment and processes needed to develop this field and expects to complete and flow test Davy Jones No. 1 by year-end 2011 and Davy Jones No. 2 in the second half of 2012. Following successful flow tests, McMoRan expects production from both wells to utilize new production facilities currently being installed.
Davy Jones involves a large ultra-deep structure encompassing four OCS lease blocks (20,000 acres). McMoRan holds a 63.4 percent working interest and a 50.2 percent net revenue interest in Davy Jones. Other working interest owners in Davy Jones include: Energy XXI (NASDAQ: EXXI) (15.8%), JX Nippon Oil Exploration (U.S.A.) Limited (12%) and Moncrief Offshore LLC (8.8%). McMoRan?s total investment in Davy Jones, which includes $483.3 million in allocated property acquisition costs, totaled
$699.6 million at September 30, 2011.

McMoRan commenced drilling the Blackbeard East ultra-deep exploration by-pass well on August
25, 2011 at 30,630 feet. The by-pass well is currently drilling below 32,000 feet to evaluate Eocene objectives encountered in the original well prior to a mechanical issue. The original well was drilled to
32,559 feet. The by-pass well is permitted to 34,000 feet.
As reported in January 2011, wireline logs indicated that Blackbeard East encountered hydrocarbon bearing sands in the Oligocene (Frio) with good porosity below 30,000 feet. The well previously encountered 178 net feet of hydrocarbons in the Miocene sands above 25,000 feet. Pressure and temperature data below the salt weld between 19,500 feet and 24,600 feet at Blackbeard East indicate that a completion at these depths could utilize conventional equipment and technologies.
Blackbeard East is located in 80 feet of water on South Timbalier Block 144. McMoRan holds a
72.0 percent working interest and a 57.4 percent net revenue interest in the well. Other working interest owners in Blackbeard East include EXXI (18.0%) and Moncrief Offshore LLC (10.0%). McMoRan?s total
investment in Blackbeard East, which includes $130.4 million in allocated property acquisition costs, totaled
$252.4 million at September 30, 2011.
The Lafitte ultra-deep exploration well, which is located on Eugene Island Block 223 in 140 feet of water, commenced drilling on October 3, 2010. Wireline logs from interim logging operations in September
2011 and recent logging operations in October 2011 indicate several Lower Miocene sands that appear to be hydrocarbon bearing. The sands have various thicknesses that aggregate approximately 250 gross feet (115 feet net), some of which are contained within a thin-bedded, sand-shale formation. These Lower Miocene aged sands are correlative to Lower Miocene sands seen onshore and in the deepwater of the GOM and provide additional confirmation of McMoRan?s ultra-deep geologic model. Lafitte is McMoRan?s third ultra-deep prospect to encounter Miocene age sands below the salt weld on the GOM Shelf.
The Lafitte well has been drilled to 28,400 feet and will be deepened to a proposed total depth of
29,950 feet to evaluate deeper Miocene objectives and possibly the Oligocene section. McMoRan holds a
72.0 percent working interest and a 58.3 percent net revenue interest in Lafitte. Other working interest owners in Lafitte include EXXI (18.0%) and Moncrief Offshore LLC (10.0%). McMoRan?s total investment in
Lafitte, which includes $35.9 million in allocated property acquisition costs, totaled $130.5 million at
September 30, 2011.
McMoRan plans to commence drilling an ultra-deep well within the Blackbeard West unit on Ship Shoal Block 188 in the fourth quarter of 2011. The well has a proposed total depth of 26,000 feet and is located approximately 4 miles west of the Blackbeard West #1 well on South Timbalier Block 168. McMoRan holds a 67.3 percent working interest and a 51.5 percent net revenue interest in the Blackbeard West well on Ship Shoal Block 188.

Shallow Water, Deep Gas Exploration Update

In addition to the ultra-deep play on the Shelf of the GOM, McMoRan?s exploration strategy is also focused on the ?deep gas play.? Deep gas prospects target large Miocene age deposits above the salt weld (i.e. listric fault) at depths typically between 15,000 to 25,000 feet.
The Boudin deep gas exploration well, which is located in 20 feet of water on Eugene Island Block
26, commenced drilling on February 27, 2011. The well is currently drilling below 23,800 feet towards a proposed total depth of 24,800 feet to evaluate Miocene objectives. McMoRan holds a 53.5 percent
working interest and a 42.4 percent net revenue interest in Boudin. EXXI holds a 20.6 percent working interest. McMoRan?s total investment in Boudin, which includes $14.8 million in allocated property acquisition costs, totaled $51.3 million at September 30, 2011.

REVENUES

McMoRan?s third-quarter 2011 oil and gas revenues totaled $134.5 million, compared to $90.8 million during the third quarter of 2010. During the third quarter of 2011, McMoRan?s sales volumes

4

totaled 11.4 Bcf of gas, 674,700 barrels of oil and condensate and 1.8 Bcfe of plant products, compared to
8.8 Bcf of gas, 534,000 barrels of oil and condensate and 1.5 Bcfe of plant products in the third quarter of
2010. McMoRan?s third-quarter comparable average realizations for gas were $4.38 per thousand cubic feet (Mcf) in 2011 and $4.61 per Mcf in 2010; for oil and condensate McMoRan received an average of
$100.94 per barrel in third-quarter 2011 compared to $75.78 per barrel in third-quarter 2010.

CASH, LIQUIDITY AND CAPITAL EXPENDITURES

At September 30, 2011, McMoRan had $642.3 million in cash. Total debt was $561.6 million at
September 30, 2011, including $261.6 million in convertible securities. McMoRan had no borrowings and
$100 million of letters of credit issued under its revolving credit facility resulting in total availability of $50 million at September 30, 2011.
On October 6, 2011 McMoRan completed an exchange offer for its $74.7 million 5¼% Convertible Senior Notes due 2011 (?existing notes?). A total of $68.2 million of the existing notes were accepted for exchange for an equal principal amount of newly issued 5¼% Convertible Senior Notes due 2012 (?new notes?). McMoRan repaid the remaining $6.5 million of the existing notes, which matured on October 6,
2011. The terms of the new notes are substantially identical to the terms of the existing notes, except that the new notes have a maturity date of October 6, 2012.
In September 2011, McMoRan acquired Whitney Exploration LLC?s (Whitney) 2.97% working interest in Davy Jones and 2% working interest in Blackbeard East. Under the terms of the transaction, McMoRan issued approximately 2.8 million shares of McMoRan common stock and paid $10 million in cash to Whitney for these interests. McMoRan?s common stock price on the closing date was $12.36 per share. Total consideration, including the assumption of certain drilling cost obligations, approximated $49 million.
McMoRan has approximately 161 million shares of common stock outstanding. Assuming conversion of McMoRan?s remaining outstanding 8% Convertible Perpetual Preferred Stock, 4% Convertible Senior Notes, 5¾% Convertible Perpetual Preferred Stock and the new notes, McMoRan would have approximately 224 million common shares outstanding on a fully converted basis.
Capital expenditures totaled $145.0 million for the third quarter of 2011 and $403.9 million for the nine-months ended September 30, 2011. McMoRan expects 2011 capital expenditures to approximate
$500-550 million, including $300-350 million for exploration and $200 million for development. Capital spending will continue to be driven by opportunities, drilling results and follow-on development activities.
Net abandonment expenditures, which include scheduled conventional and hurricane-related work, totaled $51.2 million for the third quarter of 2011 and $93.4 million for the nine-months ended September
30, 2011. Abandonment expenditures are expected to approximate $140 million in 2011.
In the third quarter of 2011, McMoRan recorded $22.6 million in gains for reimbursable costs associated with its insurance programs. Since 2009, McMoRan has recorded $115.6 million in gains associated with the 2008 hurricane events in the GOM and continues to pursue reimbursement of certain hurricane-related abandonment costs under its insurance programs.

McMoRan EXPLORATION CO.RECONCILATION OF REPORTED AMOUNTS TO NON-GAAP ITEMS (Unaudited)

EBITDAX is a financial measure commonly used in the oil and natural gas industry but is not a recognized accounting term under accounting principles generally accepted in the United States of America (GAAP). As defined by McMoRan, EBITDAX reflects the company?s adjusted oil and gas operating income (loss). EBITDAX is derived from net income (loss) from continuing operations before other income, net; interest expense, net; income tax expense; Main Pass Energy HubTM costs; exploration expenses; depletion, depreciation and amortization expense; hurricane repair charges included in production and delivery costs;
stock-based compensation charged to general and administrative expenses; insurance recoveries; gain on sale of oil and gas property; and change in fair value of oil and gas derivative contracts. EBITDAX should not be considered by itself or as a substitute for net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP, or as a measure of McMoRan?s profitability or liquidity. Because EBITDAX excludes some, but not all, items that affect net income (loss), the computation of this non-GAAP financial measure may be different from similar presentations of other companies, including oil and gas companies in our industry. As a result, the EBITDAX data presented below may not be comparable to similarly titled measures of other companies.
McMoRan?s management utilizes both the GAAP and non-GAAP results presented in this news release to evaluate McMoRan?s performance and believes that comparative analysis of results are useful to investors and other internal and external users of our financial statements in evaluating our operating performance, and such analysis can be enhanced by excluding the impact of these items to help investors meaningfully compare our results from period to period. The following is a reconciliation of reported amounts from net loss applicable to common stock to EBITDAX (in thousands):
