Financial Statements as at December 31, 2017 for more information.
Toronto, Ontario, February 21, 2018 - IAMGOLD Corporation (“IAMGOLD” or the “Company”) reported
its consolidated financial and operating results for the quarter and year ended December 31, 2017.
"It was a year of outstanding accomplishments," said IAMGOLD’s President and CEO, Steve Letwin.
"Robust operating performance, including record production at Essakane, and continued cost
improvements drove gross profit up 50% and we ended the year with $1 billion in liquidity. Exploration
results were, and continue to be, exceptional. Gold reserves rose 86% to 14.5 million ounces, as
significant increases at Rosebel and Côté Gold were followed by a 1.4 million ounce reserve estimate at
our Boto Gold Project. Boto's recent pre-feasibility results indicate the potential for a long-life, low-cost
mine. As we deliver on our strategy to increase net asset value per share, our core assets are proving to
be significant catalysts for growth. Last month we secured the exploration rights for Brokolonko near
Saramacca, another milestone in our consolidation strategy at Rosebel. In 2019, we expect production
from Saramacca and potentially heap leaching at Essakane soon after. A ramp-up to full production at
Westwood is anticipated in 2020, followed by a potential production start at Côté Gold in 2021."

Strategic Developments
• As at December 31, 2017 attributable proven and probable gold reserves were 14.5 million
ounces; up 86% from the end of 2016. Attributable measured and indicated resources (including
reserves) were 24.7 million ounces and attributable inferred resources were 8.8 million ounces; up
6% and 44%, respectively, from the end of 2016.
• Rosebel’s attributable reserves increased by 69% from the end of 2016 to 3.3 million ounces as at
December 31, 2017, reflecting mine planning optimization and cost reductions enabling access to
additional ounces.
• Declared initial resource estimate for the Saramacca gold deposit near the Rosebel mine,
comprising 1.0 million indicated ounces grading 2.20 g/t Au and 0.5 million inferred ounces grading
1.18 g/t Au (on a 100% basis). Subsequent infill and expansion drilling results identified additional
high-grade intersections. Highlights included; 3.47 g/t Au over 39.0 metres; 4.50 g/t Au over 34.5
metres and 67.39 g/t Au over 6.0 metres. These, together with remaining drill results, will be
incorporated into an updated resource model in 2018.
• Completed pre-feasibility study for the Côté Gold Project, with highlights including the conversion
of 3.8 million attributable ounces of resources to probable reserves and a 17-year mine life with
average annual attributable production of 207,000 ounces and life-of-mine all-in sustaining costs of
$689 per ounce sold.
• Completed sale of a 30% interest in the Côté Gold Project to Sumitomo Metal Mining for $195
million and established a (70:30) joint venture.

northwest of Saramacca, a property believed to be on the same mineralization trend as
Saramacca.
• Reported high-grade drilling results from the 2017 drilling program for the Diakha Deposit at the
Siribaya Project in Mali. Highlights from infill drilling included 18.0 metres grading 11.06 g/t Au,
including 6.0 metres grading 32.45 g/t Au, and from expansion drilling 16.0 metres grading 7.65 g/t
Au, including 4.0 metres grading 28.94 g/t Au.
• Announced positive pre-feasibility results for Boto Gold Project in Senegal. As at December 31,
2017, Boto had an estimated 1.4 million ounces of probable reserves grading 1.64 g/t Au.
Indicated resources (including reserves) increased by 23% to 1.9 million ounces grading 1.60 g/t
Au and inferred resources increased by 375% to 594,000 ounces grading 1.66 g/t Au from the end
of 2016. Pre-feasibility highlights include a 13.5-year mine life with life-of-mine average annual
production of nearly 100,000 ounces, and all-in sustaining costs of $829 per ounce sold. A

FULL YEAR AND FOURTH QUARTER 2017 HIGHLIGHTS
Financial Performance
• Revenues for 2017 were $1,094.9 million, up $107.8 million or 11% from 2016 primarily due to higher
sales volume at Westwood ($70.6 million), Essakane ($11.9 million) and Rosebel ($9.6 million),
combined with a higher realized gold price ($14.5 million). Revenues for the fourth quarter 2017 were
$291.1 million, up $38.6 million or 15% from the same prior year period primarily due to higher sales
volume at Westwood ($21.0 million) and Essakane ($4.8 million), and a higher realized gold price
($19.9 million), partially offset by lower sales at Rosebel ($7.6 million).
• Cost of sales for 2017 was $942.0 million, up $57.1 million or 6% from 2016. The increase was due to
higher operating costs ($52.1 million), depreciation ($4.1 million) and royalty expense ($0.9 million).
Operating costs were higher mainly due to a 73,000 attributable ounce increase in sales at our owner-
operator sites, with sales nearly doubling at Westwood and higher sales at both Rosebel and
Essakane. Cost of sales for the fourth quarter 2017 was $250.0 million, up $16.6 million or 7% from
the same prior year period. The increase was due to higher operating costs ($16.1 million) and royalty
expense ($0.5 million) as depreciation remained unchanged. Operating costs were higher primarily
due to a 15,000 attributable ounce increase in sales, with Westwood's sales doubling from the same
prior year period.
• Depreciation expense for 2017 was $265.4 million, up $4.1 million from 2016, primarily due to higher
amortization of capitalized stripping and higher production, partially offset by lower depreciation at
Rosebel due to an increase in reserves. Depreciation expense for the fourth quarter 2017 was $68.2
million, unchanged from the same prior year period primarily due to the increase in reserves at
Rosebel offset by higher amortization of capitalized stripping.
• Income tax expense for 2017 was $97.6 million, up $64.2 million from 2016. Income tax expense for
2017 comprised current income tax expense of $59.7 million (2016 - $21.7 million) and deferred tax
expense of $37.9 million (2016 - $11.7 million). The increase in income tax expense in 2017 was
primarily due to differences in the level of taxable income in IAMGOLD's operating jurisdictions from
4
one period to the next and changes in deferred tax assets and liabilities as a result of impairment
reversals.
• Net earnings attributable to equity holders for 2017 were $501.6 million ($1.08 per share), up $449.0
million ($0.95 per share) from 2016. The increase was due to impairment reversals relating to the Côté
Gold Project and the Rosebel mine ($524.1 million), and higher gross profit ($50.7 million), partially
offset by the gain on the sale of gold bullion in 2016 ($72.9 million) and higher income taxes ($64.2
million) in 2017. Net loss attributable to equity holders for the fourth quarter 2017 was $17.7 million
($0.04 per share), up $12.4 million ($0.03 per share) from the same prior year period. The increase
was due to higher income tax expense ($31.3 million), partially offset by a higher share of net earnings
from investments in associates and joint ventures ($6.2 million), lower foreign exchange loss ($4.7
million), higher interest and other investment income ($3.6 million) and lower finance costs ($2.2
million).
• Adjusted net earnings attributable to equity holders2 for 2017 were $29.3 million ($0.06 per share2), up
$25.4 million ($0.05 per share2) from 2016. Adjusted net loss attributable to equity holders for the
fourth quarter 2017 was $13.8 million ($0.03 per share2), compared to adjusted net earnings
attributable to equity holders of $3.3 million ($0.01 per share2) in the same prior year period.
• Net cash from operating activities for 2017 was $295.3 million, down $15.8 from 2016. The decrease
was due to an increase in income tax paid ($33.7 million) and changes in the movement of non-cash
working capital items ($18.3 million), partially offset by higher earnings after non-cash adjustments
($36.8 million). Net cash from operating activities for the fourth quarter 2017 was $65.2 million, up $1.4
million from the same prior year period.
• Net cash from operating activities before changes in working capital2 for 2017 was $294.0 million, up
$2.5 million from 2016. Net cash from operating activities before changes in working capital2 for the
fourth quarter 2017 was $68.2 million, up $5.6 million from the same prior year period.
Financial Position
• We ended the year in a strong financial position with cash, cash equivalents, short-term investments in
money market instruments, and restricted cash totalling $815.8 million at December 31, 2017, up
$53.1 million from December 31, 2016. The increase was primarily due to net proceeds from the
issuance of the 7% Senior Notes ($393.6 million), which extended the term of our debt by five years to
2025. A continued focus on improving costs contributed to the generation of $295.3 million in cash
from operating activities. Further, the Company received net proceeds from the sale of a 30% interest
in the Côté Gold Project, to form a joint venture with Sumitomo Metal Mining Co., Ltd. ($96.5 million).
We also benefited from proceeds from the issuance of flow-through shares ($15.1 million). The
increase was partially offset by the redemption of the 6.75% Senior Notes ($505.6 million), and
spending on Property, plant and equipment and Exploration and evaluation assets, including
capitalized borrowing costs ($234.5 million).
Production and Costs
• Attributable gold production, inclusive of joint venture operations, was 882,000 ounces in 2017, up
69,000 ounces from 2016. The increase was primarily due to the continued ramp-up at Westwood
(60,000 ounces), higher throughput at Essakane (12,000 ounces) and Rosebel (6,000 ounces),
partially offset by lower grades at Sadiola (7,000 ounces), and the closure of Yatela (2,000 ounces).
Attributable gold production, inclusive of joint venture operations, was 228,000 ounces in the fourth
quarter 2017, up 13,000 ounces from the same prior year period. The increase was due to the
continued ramp-up at Westwood (11,000 ounces) and higher throughput at Essakane (6,000 ounces),
partially offset by lower grades at Rosebel (4,000 ounces).
• Attributable gold sales, inclusive of joint venture operations, were 871,000 ounces in 2017, up 63,000
ounces from 2016, primarily due to higher sales at Westwood (57,000 ounces), Essakane (8,000
ounces), and Rosebel (8,000 ounces), partially offset by lower sales at the Joint Ventures (10,000
ounces). Attributable gold sales, inclusive of joint venture operations, were 230,000 ounces for the
fourth quarter 2017, up 12,000 ounces from the same prior year period, primarily due to higher sales at
Westwood (18,000 ounces) and Essakane (3,000 ounces), partially offset by lower sales at Rosebel
(6,000 ounces) and the Joint Ventures (3,000 ounces).
5
• Cost of sales1 per ounce for 2017 was $783, down 1% from 2016 due to higher sales volume, partially
offset by lower capitalized stripping and higher energy costs. Cost of sales per ounce for the fourth
quarter 2017 was $802, up 2% from the same prior year period primarily due to higher energy costs,
and a weaker U.S. dollar relative to the euro and the Canadian dollar, partially offset by higher sales
volume.
• Total cash costs2 per ounce produced for 2017 were $755, up 2% from 2016 primarily due to lower
capitalized stripping, and higher energy costs. Total cash costs for the fourth quarter 2017 were $751
per ounce produced, up 2% from the same prior year period primarily due to higher energy costs, and
a weaker U.S. dollar relative to the euro and the Canadian dollar.
The normalization of Westwood's costs was discontinued in the second quarter 2017, and as such,
total cash costs for the year ended and fourth quarter 2017 included a reduction of $1 and $nil per
ounce, respectively (2016 - $32 and $44 per ounce). Also included in total cash costs for the year
ended and fourth quarter 2017 were realized derivative gains from hedging programs of $3 and $7 per
ounce, respectively (2016 - losses of $1 and $nil per ounce).
• All-in sustaining costs2 per ounce sold for 2017 were $1,003, down 5% from 2016 primarily as a result
of lower sustaining capital expenditures. All-in sustaining costs1 per ounce sold for the fourth quarter
2017 were $1,071, up 8% from the same prior year period primarily as a result of higher sustaining
capital expenditures and higher cost of sales.
As noted above, with the normalization of Westwood's costs discontinued in the second quarter 2017,
all-in sustaining costs for the year ended and fourth quarter 2017 included a reduction of $1 and $nil
per ounce, respectively (2016 - $33 and $43 per ounce). Also included in all-in sustaining costs for the
year ended and fourth quarter 2017 were realized derivative gains from hedging programs of $4 and
$9 per ounce, respectively (2016 - losses of $1 and $nil).
Commitment to Zero Harm Continues
• The DART rate3, representing the frequency of all types of serious injuries across IAMGOLD, was 0.52
in 2017, below our target of 0.56. We regret the fatality of an employee at the Westwood mine during
the first quarter of 2017.

2018 GUIDANCE
Refer to the January 16, 2018 news release
Attributable Gold Production - 850,000 to 900,000 oz
Costs
Cost of Sales1/oz $765 - $815
Total Cash Costs2/oz produced $750 - $800
All-in Sustaining Costs2/oz sold $990 - $1,070
Attributable gold production in 2018 is expected to trend upwards in the second half of the year. Westwood
will continue to focus on underground development, with 125,000 to 135,000 ounces expected for the year.
Rosebel's higher grades and improving productivity are expected to drive production higher (295,000 to
310,000 expected) despite lower throughput anticipated with the proportion of hard rock approaching 60%.
At Essakane (380,000 to 395,000 ounces expected), grades and recoveries are expected to increase
while throughput is expected to be lower than the record throughput in 2017. The Sadiola Joint Venture is
expected to produce between 50,000 and 60,000 ounces. With the continued focus on performance
optimization and cost reductions across the sites, we expect total cash costs2 and all-in sustaining costs2
per ounce to trend downwards in the second half of the year.
Capital Expenditures - $365 million ± 5%
Capital expenditures in 2018 are expected to be significantly higher than the $220.5 million spent in 2017
as a result of advancing multiple growth projects as outlined below in the non-sustaining capital section.
Sustaining Capital - $140 million - Consistent with 2017 spending.
Sustaining capital guidance of $140 million is similar to 2017. While total capitalized stripping of $45 million
is expected to be at a level similar to 2017, an increase is expected at Essakane reflecting higher mining
activity at Falagountou, with an offsetting decrease expected at Rosebel as strip ratios decrease as the ore
body is reached in active phases. Rosebel's strip ratios are expected to be higher in 2019.
Non-Sustaining Capital (Development/Expansion) - $225 million - Advancing growth projects.
Non-sustaining capital guidance of $225 million includes $85 million at Rosebel, predominantly for initial
development work at Saramacca, with a production start expected in the second half of 2019; $75 million
at Essakane, which includes an initial $30 million for the Heap Leach Project, with construction expected to
commence in the second half of 2018; and $45 million at Westwood primarily for expansion/ramp-up
development. The $15 million for corporate and development projects is primarily related to the Côté Gold
Project feasibility study targeted for completion in the first half of 2019. The $5 million for Sadiola includes
previous commitments related to the Sulphide Project. Capital spending estimates could be updated
throughout the year as additional studies are completed.
Depreciation
Depreciation expense in 2018 is expected to be between $275 and $285 million.
Income Taxes
Cash taxes in 2018 are expected to range between $40 and $55 million. Additionally, adjustments to
deferred tax assets and/or liabilities may be recorded during the year.

OPERATIONS ANALYSIS BY MINE SITE
Essakane Mine - Burkina Faso (IAMGOLD interest - 90%)
Essakane achieved record gold production in 2017 as mill throughput exceeded nameplate capacity. This
reflected an updated SAG mill liner design and improved operating and maintenance practices, which
increased mill capacity, speed, and circuit availability.
Attributable gold production of 102,000 ounces for the fourth quarter and 389,000 ounces for the full year
2017 was up 6% and 3% from the same prior year periods, respectively. The increases were due to higher
throughput and recoveries, partially offset by lower grades.
8
Mill throughput of 13.9 million tonnes in 2017 exceeded nameplate capacity of 10.8 million tonnes, despite
86% hard rock. And mill throughput for the fourth quarter was higher than the same prior year period
despite 85% hard rock content (2016 - 65%).
Due to mine sequencing, grades were lower in the fourth quarter 2017 compared to the same prior year
period. Mining activities increased as a result of ongoing initiatives to increase equipment availability and
productivity, including the addition of two production drills and a loader. Mill recoveries continue to improve
as mining continues in non-graphitic zones.
Cost of sales per ounce was $792 for the fourth quarter 2017 and $785 for the full year, up 9% and 10%,
respectively, from the same prior year periods. The increases were primarily due to lower capitalized
stripping costs due to mine sequencing, higher energy costs, higher processing costs due to increased
throughput and a higher proportion of hard rock, and a weaker US dollar relative to the euro.
Total cash costs per ounce produced were $715 for the fourth quarter 2017 and $738 for the full year, up
4% and 10%, respectively, from the same prior year periods. The increases were mainly due to higher
costs of sales for the reasons mentioned above. Total cash costs per ounce for the fourth quarter and full
year 2017 included the positive impact of realized derivative gains from hedging programs of $12 and $5
per ounce, respectively (2016 - losses of $1 for both periods).
All-in sustaining costs per ounce sold were $990 for the fourth quarter 2017, up 4% from the same prior
year period mainly due to higher cost of sales, partially offset by higher sales volume and lower sustaining
capital expenditures. All-in sustaining costs per ounce were $957 for the full year 2017, lower than the
previous year by 2% mainly due to lower sustaining capital expenditures and higher sales volume, partially
offset by higher cost of sales. Included in all-in sustaining costs for the fourth quarter and full year 2017
was the positive impact of realized derivative gains from hedging programs of $14 and $6 per ounce,
respectively (2016 - losses of $1 and $nil).
Outlook
Essakane’s attributable production for 2018 is expected to be between 380,000 and 395,000 ounces.
Essakane continues to focus on optimizing production by increasing mining and milling efficiencies at
higher proportions of hard rock. To improve recoveries, we expect to complete the geometallurgical study
by the end of the first quarter 2018. The study is expected to improve the ability to better identify pockets of
graphitic ore. The oxygen plant, which is expected to increase recoveries through improved leach kinetics
and improve the efficiency of the circuit by reducing reagent consumption, is to be commissioned at the
end of 2018.
The pre-feasibility study on the Heap Leach Project is expected to be completed by the second quarter
2018. A heap leach facility could provide a low-cost method for processing marginal and low grade
mineralization as well as some existing stockpiles, which, together with the carbon-in-leach (CIL) plant,
would provide significant upside potential to the site’s annual production. Additionally, a combined heap
leach/CIL operation provides a strong opportunity to justify additional pushbacks to extend the life of the
operation.
The construction of the solar power plant, which commenced during the second quarter 2017, is expected
to be completed by the end of the first quarter 2018.
Essakane continues to focus on resource expansion in areas adjacent to and at depth below the Essakane
pit.
Essakane's strong mill performance, ongoing performance optimization, growth potential from heap
leaching, and a highly prospective land package, provide significant upside to its current life of mine plan.
Rosebel Mine - Suriname (IAMGOLD interest - 95%)
Attributable gold production for the fourth quarter 2017 was 79,000 ounces compared to 83,000 ounces in
the same prior year period. The lower production was due mainly to lower grades. Despite 49% hard rock
content in the fourth quarter 2017 (2016 - 26%), throughput continued to benefit from major mill
improvements completed in 2016. Further improvements to maximize SAG mill performance and reduce
power consumption are on-going. For the full year, attributable production was 302,000 ounces, up 2%
from 2016 due to higher throughput and grades, partially offset by lower recoveries.
