SUMMARY FINANCIAL AND OPERATING DATA

OPERATIONS

Consolidated. First-quarter 2013 consolidated copper sales of 954
million pounds were higher than the January 2013 estimate of 940 million
pounds (primarily reflecting higher production and sales from Africa)
and also higher than first-quarter 2012 sales of 827 million pounds
primarily because of higher production from Indonesia and Africa.

First-quarter 2013 consolidated gold sales of 214 thousand ounces were
lower than the January 2013 estimate of 230 thousand ounces (primarily
reflecting timing of shipments) and lower than first-quarter 2012 sales
of 288 thousand ounces primarily because of anticipated lower ore grades
in Indonesia.

First-quarter 2013 consolidated molybdenum sales of 25 million pounds
were higher than the January 2013 estimate of 23 million pounds and
first-quarter 2012 sales of 21 million pounds primarily because of
stronger sales in the metallurgical and chemical sectors.

Consolidated sales from mines for the year 2013 are expected to
approximate 4.3 billion pounds of copper, 1.4 million ounces of gold and
92 million pounds of molybdenum, including 1.0 billion pounds of copper,
295 thousand ounces of gold and 23 million pounds of molybdenum for
second-quarter 2013.

As anticipated, consolidated average unit net cash costs (net of
by-product credits) of $1.57 per pound of copper in first-quarter 2013
were higher than unit net cash costs of $1.26 per pound in first-quarter
2012 reflecting lower by-product credits.

Assuming average prices of $1,400 per ounce of gold and $11 per pound of
molybdenum for the remainder of 2013 and achievement of current sales
volume and cost estimates, consolidated unit net cash costs (net of
by-product credits) for FCX's copper mining operations are expected to
average approximately $1.45 per pound of copper for the year 2013.
Projected unit net cash costs for 2013 are higher than previous
estimates primarily because of lower gold credits. The impact of price
changes for the remainder of 2013 on consolidated unit net cash costs
would approximate $0.015 per pound for each $50 per ounce change in the
average price of gold and $0.01 per pound for each $2 per pound change
in the average price of molybdenum. Quarterly unit net cash costs vary
with fluctuations in sales volumes and average realized prices
(primarily gold and molybdenum prices), and are expected to decline
during the second half of the year as FCX gains access to higher grade
ore in Indonesia (54 percent of 2013 consolidated copper sales volumes
and 63 percent of consolidated gold sales volumes are expected in the
second half of 2013).

North America Copper Mines. FCX operates seven open-pit copper
mines in North America - Morenci, Bagdad, Safford, Sierrita and Miami in
Arizona, and Chino and Tyrone in New Mexico. All of the North America
mining operations are wholly owned, except for Morenci. FCX records its
85 percent joint venture interest in Morenci using the proportionate
consolidation method. In addition to copper, certain of FCX's North
America copper mines (Sierrita, Bagdad, Morenci and Chino) also produce
molybdenum concentrates, which are sold to FCX's molybdenum sales
company at market-based pricing.

Operating and Development Activities. FCX has increased
production from its North America copper mines in recent years and
continues to evaluate a number of opportunities to invest in additional
production capacity at several of its North America copper mines in
response to positive exploration results in recent years.

At Morenci, FCX is expanding mining and milling capacity to process
additional sulfide ores identified through exploratory drilling. The
approximate $1.4 billion project is targeting incremental annual
production of approximately 225 million pounds of copper in 2014 (an
approximate 40 percent increase from 2012) through an increase in
milling rates from 50,000 metric tons of ore per day to approximately
115,000 metric tons of ore per day and mining rates from 700,000 short
tons per day to 900,000 short tons per day. The targeted increase in
mining rates has been achieved, engineering activities are nearing
completion and construction activities for the new mill and related
facilities are in progress.

Operating Data. Following is summary consolidated operating data
for the North America copper mines for the first quarters of 2013 and
2012:

Consolidated copper sales volumes from North America of 353 million
pounds in first-quarter 2013 were higher than first-quarter 2012 sales
of 338 million pounds primarily reflecting increased production at the
Chino mine.

FCX expects sales from the North America copper mines to approximate
1.45 billion pounds of copper for the year 2013, compared with 1.35
billion pounds in 2012, primarily reflecting higher production at
Morenci and Chino.

Average unit net cash costs (net of by-product credits) for the North
America copper mines of $1.86 per pound of copper in first-quarter 2013
were higher than unit net cash costs of $1.51 per pound in first-quarter
2012 primarily reflecting higher mining rates and lower molybdenum
credits.

FCX estimates that average unit net cash costs (net of by-product
credits) for the North America copper mines would approximate $1.89 per
pound of copper for the year 2013, based on current sales volume and
cost estimates and assuming an average molybdenum price of $11 per pound
for the remainder of 2013. North America's average projected unit net
cash costs would change by approximately $0.025 per pound for each $2
per pound change in the average price of molybdenum for the remainder of
2013.

South America Mining. FCX operates four copper mines in South
America - Cerro Verde in Peru and El Abra, Candelaria and Ojos del
Salado in Chile. FCX owns a 53.56 percent interest in Cerro Verde, a 51
percent interest in El Abra, and an 80 percent interest in both the
Candelaria and Ojos del Salado mining complexes. All operations in South
America are consolidated in FCX's financial statements. South America
mining includes open-pit and underground mining. In addition to copper,
the Candelaria and Ojos del Salado mines produce gold and silver, and
the Cerro Verde mine produces molybdenum concentrates that are sold to
FCX's molybdenum sales company at market-based pricing.

Operating and Development Activities. FCX has commenced initial
construction activities associated with a large-scale expansion at Cerro
Verde. The project, with an estimated cost of $4.4 billion, will expand
the concentrator facilities from 120,000 metric tons of ore per day to
360,000 metric tons of ore per day and provide incremental annual
production of approximately 600 million pounds of copper and 15 million
pounds of molybdenum beginning in 2016.

FCX continues to engage in studies to evaluate a potential large-scale
milling operation at El Abra to process additional sulfide material and
to achieve higher recoveries. Exploration results at El Abra indicate
the potential for a significant sulfide resource.

Operating Data. Following is summary consolidated operating data
for the South America mining operations for the first quarters of 2013
and 2012:

Consolidated copper sales volumes from South America of 285 million
pounds in first-quarter 2013 approximated first-quarter 2012 sales of
286 million pounds as higher grade ore at Candelaria offset lower grade
ore at Cerro Verde.

FCX expects South America's sales to approximate 1.34 billion pounds of
copper for the year 2013, compared with sales of 1.25 billion pounds of
copper in 2012, primarily reflecting higher grade ore at Candelaria.

Average unit net cash costs (net of by-product credits) for South
America of $1.51 per pound of copper in first-quarter 2013 were higher
than unit net cash costs of $1.40 per pound in first-quarter 2012
primarily reflecting higher costs for maintenance and repairs.

FCX estimates that average unit net cash costs (net of by-product
credits) for South America mining would approximate $1.44 per pound of
copper for the year 2013, based on current sales volume and cost
estimates and assuming average prices of $1,400 per ounce of gold and
$11 per pound of molybdenum for the remainder of 2013.

Indonesia Mining. Through its 90.64 percent owned and wholly
consolidated subsidiary PT Freeport Indonesia, FCX's assets include one
of the world's largest copper and gold deposits at the Grasberg minerals
district in Papua, Indonesia. PT Freeport Indonesia produces copper
concentrates, which contain significant quantities of gold and silver.

Operating and Development Activities. FCX has several projects in
progress in the Grasberg minerals district, primarily related to the
development of large-scale, high-grade underground ore bodies. In
aggregate, these underground ore bodies are expected to ramp up over
several years to produce approximately 240,000 metric tons of ore per
day following the currently anticipated transition from the Grasberg
open pit in 2017. Development of the Grasberg Block Cave and Deep Mill
Level Zone (DMLZ) is advancing according to schedule, which would enable
the DMLZ to commence production in 2015 and the Grasberg Block Cave mine
to commence production in 2017. Over the next five years, estimated
aggregate capital spending on these projects is currently expected to
average $735 million per year ($585 million per year net to PT Freeport
Indonesia).

Operating Data. Following is summary consolidated operating data
for the Indonesia mining operations for the first quarters of 2013 and
2012:

Indonesia's first-quarter 2013 copper sales of 198 million pounds were
higher than first-quarter 2012 copper sales of 134 million pounds when
labor-related disruptions affected operations. Productivity measures
have continued to improve resulting in first-quarter 2013 daily mill
throughput averaging 199,400 metric tons per day, including 59,000
metric tons per day from the Deep Ore Zone (DOZ) underground mine.

As expected, Indonesia's first-quarter 2013 gold sales of 191 thousand
ounces were lower than first-quarter 2012 gold sales of 266 thousand
ounces primarily as a result of lower ore grades from mine sequencing.

At the Grasberg mine, the sequencing of mining areas with varying ore
grades causes fluctuations in the timing of ore production resulting in
varying quarterly and annual sales of copper and gold. FCX expects sales
from Indonesia to approximate 1.1 billion pounds of copper and 1.25
million ounces of gold for the year 2013, compared with 716 million
pounds of copper and 915 thousand ounces of gold for the year 2012. FCX
expects sales from Indonesia to increase in the second half of 2013 as
PT Freeport Indonesia gains access to higher ore grades and achieves the
targeted ramp up in production from the DOZ underground mine to
approximately 80,000 metric tons per day (57 percent of Indonesia's
projected copper sales and 63 percent of Indonesia's projected gold
sales are expected in the second half of 2013).

Indonesia's unit net cash costs (including gold and silver credits) of
$1.34 per pound of copper in first-quarter 2013 were higher than unit
net cash costs of $0.33 per pound in first-quarter 2012 primarily
reflecting lower gold credits, partly offset by higher copper sales
volumes.

FCX estimates Indonesia's average unit net cash costs (net of gold and
silver credits) would approximate $1.00 per pound of copper for the year
2013, based on current sales volume and cost estimates and assuming an
average gold price of $1,400 per ounce for the remainder of 2013.
Projected unit net cash costs for 2013 are higher than previous
estimates primarily because of lower gold credits. Indonesia's projected
unit net cash costs would change by approximately $0.05 per pound for
each $50 per ounce change in the average price of gold for the remainder
of 2013. Because of the fixed nature of a large portion of Indonesia's
costs, unit costs vary from quarter to quarter depending on copper and
gold sales volumes, as well as average realized gold prices for the
quarterly period. Indonesia's unit net cash costs are expected to
decline during the second half of the year as it gains access to higher
grade ore.

Africa Mining. Through its 56 percent owned and wholly
consolidated subsidiary Tenke Fungurume Mining S.A.R.L. (TFM), FCX
operates the Tenke Fungurume (Tenke) mine in the Katanga province of the
Democratic Republic of Congo (DRC). In addition to copper, the Tenke
mine produces cobalt hydroxide.

Operating and Development Activities. TFM has completed its
second phase expansion project, which included optimizing the current
plant and increasing mine, mill and processing capacity. The expanded
mill is capable of throughput of 14,000 metric tons of ore per day to
enable increasing copper production by 150 million pounds to over 430
million pounds per year. Costs incurred to date total approximately $615
million and included mill upgrades, additional mining equipment and a
new tankhouse. A second sulphuric acid plant, which was included in the
$850 million total estimated project capital cost, is expected to be
installed in 2015. The expanded mill facility is performing well, with
first-quarter 2013 average throughput rates of 14,600 metric tons per
day.

FCX continues to engage in drilling activities, exploration analyses and
metallurgical testing to evaluate the potential of the highly
prospective minerals district at Tenke. These analyses are being
incorporated in future plans to evaluate opportunities for expansion.
Future expansions are subject to a number of factors, including economic
and market conditions, and the business and investment climate in the
DRC.

Operating Data. Following is summary consolidated operating data
for the Africa mining operations for the first quarters of 2013 and 2012:

Africa mining operations established new records in first-quarter 2013
for mining, milling and copper sales. Copper sales from Africa of 118
million pounds in first-quarter 2013 were higher than first-quarter 2012
copper sales of 69 million pounds primarily reflecting higher mining and
milling rates principally related to the ramp up of the expansion
project and higher ore grades.

FCX expects Africa's sales to approximate 435 million pounds of copper
and 28 million pounds of cobalt for the year 2013, compared with 336
million pounds of copper and 25 million pounds of cobalt for the year
2012.

Africa's unit net cash costs (net of cobalt credits) of $1.23 per pound
of copper in first-quarter 2013 were slightly lower than unit net cash
costs of $1.25 per pound in first-quarter 2012, primarily reflecting the
benefit of higher sales volumes, partly offset by lower cobalt credits.

FCX estimates Africa's average unit net cash costs would approximate
$1.18 per pound of copper for the year 2013, based on current sales
volume and cost estimates and assuming an average cobalt price of $12
per pound for the remainder of 2013. Africa's projected unit net cash
costs would change by approximately $0.065 per pound for each $2 per
pound change in the average price of cobalt for the remainder of 2013.

Freeport Cobalt. On March 29, 2013, through the newly formed and
wholly consolidated Freeport Cobalt joint venture, FCX acquired a
large-scale cobalt chemical refinery located in Kokkola, Finland, and
the related sales and marketing business. FCX is the operator of the
joint venture with an effective 56 percent ownership interest. The
remaining effective ownership interests are held by FCX's partners in
TFM, including 24 percent by Lundin Mining Corporation and 20 percent by
La G?n?rale des Carri?res et des Mines.

This acquisition enhances FCX's cobalt marketing position, product
portfolio and product development capabilities, and provides direct
end-market access for the cobalt hydroxide production from TFM.

Initial consideration paid was $355 million, including $34 million of
acquired cash. Under the terms of the agreement, there is the potential
for additional consideration of up to $110 million over a period of
three years, contingent upon the achievement of revenue-based
performance targets. The acquisition was funded 70 percent by FCX and 30
percent by Lundin, which amounts will be repaid prior to any shareholder
distributions.

Molybdenum Mines. FCX has two wholly owned molybdenum mines in
North America ? the Henderson underground mine and the Climax open-pit
mine, both in Colorado. The Henderson and Climax mines produce
high-purity, chemical-grade molybdenum concentrates, which are typically
further processed into value-added molybdenum chemical products.

Operating Data. Following is summary consolidated operating data
for the molybdenum mines for the first quarters of 2013 and 2012:

The Climax molybdenum mine was commissioned in second-quarter 2012 and
includes a new 25,000 metric ton per day mill facility. Molybdenum
production from the Climax mine totaled 5 million pounds in
first-quarter 2013 and is targeted at 20 million pounds for the year
2013 (with potential to produce up to approximately 30 million pounds
per year, depending on market conditions). FCX intends to operate the
Climax and Henderson mines in a flexible manner to meet market
requirements.

Average unit net cash costs for FCX's molybdenum mines were $7.32 per
pound of molybdenum in first-quarter 2013, compared with $6.88 per pound
in first-quarter 2012, reflecting higher input costs at Henderson and
the addition of production from Climax.

Based on current sales volume and cost estimates, FCX expects unit net
cash costs for the molybdenum mines to average approximately $7.25 per
pound of molybdenum for the year 2013 (reflecting approximately $7.50
per pound for Henderson and $6.90 per pound for Climax).

EXPLORATION ACTIVITIES

FCX is actively conducting exploration activities near its existing
mines with a focus on opportunities to expand reserves that will support
the development of additional future production capacity in the large
minerals districts where it currently operates. Exploration results
indicate opportunities for significant future potential reserve
additions in North and South America and in the Tenke Fungurume minerals
district. The drilling data in North America continue to indicate the
potential for expanded sulfide production.

Exploration spending is expected to approximate $235 million for the
year 2013, compared to $251 million in 2012. Exploration activities will
continue to focus primarily on the potential for future reserve
additions in FCX's existing minerals districts. Approximately one-third
of the 2013 budget is associated with global greenfield exploration
projects.

CASH FLOWS

FCX generated operating cash flows of $831 million (net of $430 million
in working capital uses and changes in other tax payments) for
first-quarter 2013. Excluding results from pending acquisitions, based
on current sales volume and cost estimates and assuming average prices
of $3.25 per pound of copper, $1,400 per ounce of gold and $11 per pound
of molybdenum for the remainder of 2013, FCX's consolidated operating
cash flows are estimated to approximate $5.5 billion (including $0.4
billion in net working capital sources and changes in other tax
payments) for the year 2013. The impact of price changes during the
remainder of 2013 on operating cash flows would approximate $270 million
for each $0.10 per pound change in the average price of copper, $50
million for each $50 per ounce change in the average price of gold and
$80 million for each $2 per pound change in the average price of
molybdenum.

Capital expenditures totaled $805 million for first-quarter 2013.
Excluding amounts for pending acquisitions, capital expenditures are
currently estimated to approximate $4.4 billion for the year 2013
(including $2.6 billion for major projects and $1.8 billion for
sustaining capital). Major projects for 2013 primarily include the
expansions at Cerro Verde and Morenci and underground development
activities at Grasberg. FCX is also considering additional investments
at several of its sites. Capital spending plans will continue to be
reviewed and adjusted in response to changes in market conditions and
other factors.

Other investing activities for first-quarter 2013 included $321 million
(net of cash acquired) for payments by the Freeport Cobalt joint venture
to fund the March 2013 acquisition of a cobalt chemical refinery.

CASH AND DEBT

Following is a summary of cash available to the parent company, net of
noncontrolling interests' share, taxes and other costs at March ?31, 2013
(in billions):

At March ?31, 2013, FCX had $10.1 billion in debt, including the March
2013 issuance of $6.5 billion of senior notes.

During first-quarter 2013, FCX sold $6.5 billion of senior notes in four
tranches and also entered into an agreement for a $4.0 billion bank term
loan (the Term Loan). No amounts are currently available to FCX under
the Term Loan, which will be funded at closing of the PXP and MMR
acquisitions. The weighted-average interest rate of these financings
approximates 3.1 percent. FCX expects to use the net proceeds from these
financings to fund the pending acquisitions of PXP and MMR, including
for the payment of cash consideration for the acquisitions and the
repayment of certain indebtedness of PXP and MMR. If the PXP acquisition
is not completed, FCX will be required to redeem all the outstanding
7-year, 10-year and 30-year notes (which total $5 billion) at 101
percent plus accrued and unpaid interest.

At March ?31, 2013, FCX had no borrowings and $43 million of letters of
credit issued under its revolving credit facility, resulting in
availability of $1.5 billion. In February 2013, FCX entered into a new
$3.0 billion senior unsecured revolving credit facility, which will
refinance and replace its existing revolving credit facility upon
completion of the pending acquisition of PXP.

FINANCIAL POLICY

FCX has a long-standing tradition of seeking to build shareholder value
through investing in projects with attractive rates of return and
returning cash to shareholders through common stock dividends and share
purchases. FCX paid common stock dividends of $297 million in
first-quarter 2013. FCX's current annual dividend rate for its common
stock is $1.25 per share. On March 27, 2013, FCX's Board of Directors
(the Board) declared a regular quarterly dividend of $0.3125 per share,
which will be paid on May 1, 2013. FCX intends to continue to maintain a
strong financial position, invest aggressively in attractive growth
projects and provide cash returns to shareholders. The Board will
continue to review FCX's financial policy on an ongoing basis.

PENDING ACQUISITIONS OF PXP AND MMR

On December 5, 2012, FCX announced definitive agreements to acquire, in
separate transactions, PXP and MMR. PXP per-share consideration is
equivalent to 0.6531 shares of FCX common stock and $25 in cash. MMR
per-share consideration consists of $14.75 in cash and 1.15 units of a
royalty trust, which will hold a five percent overriding royalty
interest in future production of MMR's existing shallow water ultra-deep
prospects. The combined company would be a premier U.S.-based natural
resource company with a growing production profile and an industry
leading global portfolio of mineral assets and significant oil and gas
resources. The addition of a high quality, North America-focused oil and
gas resource base is expected to provide strong current cash flows and
significant growth potential, enhanced geographic diversification and
complementary exposure to markets positioned for global growth.

Completion of each transaction is subject to receipt of PXP and MMR
stockholder approval of their respective transaction. The PXP
transaction is not conditioned on the closing of the MMR transaction,
and the MMR transaction is not conditioned on the closing of the PXP
transaction. The transactions are expected to close in second-quarter
2013, subject to satisfaction of all conditions to closing.
