GLOBAL COVID-19 PANDEMIC

The global COVID-19 pandemic continues to evolve including the continuing imposition of restrictions on the movement of people and goods, social distancing measures, restrictions on group gatherings, quarantine requirements and contact tracing. IAMGOLD has been closely monitoring and taking necessary measures to manage the impact of the COVID-19 pandemic on its operations, development projects and exploration activities. IAMGOLD is managing the financial and operational challenges of COVID-19 while rapidly addressing the needs of its employees and the communities where IAMGOLD operates. IAMGOLD continues to work closely with local and national governments and communities on limiting the impact of the COVID-19 pandemic on its people and business, and supporting local efforts to manage the pandemic.
IAMGOLD has taken extensive steps, across its operations and offices, to protect the health and safety of employees, contractors and local communities in response to the COVID-19 pandemic. These steps included: implementation of sanitary measures recommended by Health Authorities and COVID-19 prevention protocols. The protocols address risk controls, including: restricting site access to employees, contractors and incoming supplies; screening processes (the use of external laboratories for PCR testing, the acquisition of Antigen test kits and the use of thermal cameras to check temperatures before entering the sites); physical distancing; the use of personal protective equipment; arranging additional transportation buses and increasing on-site medical personnel.

STRATEGIC DEVELOPMENTS

IAMGOLD’s transformational strategy centres on delivering the lower cost Côté Gold Project, de-risking the Boto Gold Project, optimizing its current operations and continuing to invest in its pipeline of brownfield and greenfield exploration. Together with its financial strategy of maintaining a strong balance sheet, IAMGOLD expects to secure favourable hedges on cost inputs and protective hedges on a portion of gold production during construction of the Côté Gold Project as appropriate, management believes IAMGOLD is positioned to deliver on its goal of superior returns to shareholders.

Financial

On December 30, 2020, IAMGOLD together with its joint venture partner AngloGold Ashanti Limited (“AGA”) completed the sale of their collective interest in Société d’Exploitation des Mines d’Or de Sadiola S.A. (“Sadiola”) to Allied Gold Corp (“Allied Gold”). Upon closing, IAMGOLD and AGA each received $25 million. In addition, on January 4, 2021, IAMGOLD and AGA each received additional consideration of $1.8 million based upon the amount by which the cash balance of Sadiola at April 30, 2020 was greater than the amount agreed pursuant to the agreement entered into by IAMGOLD and AGA with Allied Gold in December 2019.
During the third quarter 2020, IAMGOLD implemented a gold hedging strategy to mitigate gold price exposure and to further strengthen the balance sheet during the Côté Gold Project construction period. IAMGOLD intends, under appropriate conditions, to hedge 15% to 20% of total production between 2021 and mid-2023 through a combination of options and/or collars (see news release dated July 21, 2020). During the fourth quarter, IAMGOLD executed gold hedges for 2021 in the range of $1,600 to $2,800 per ounce on 78,040 ounces, for which a premium of $1.3 million was paid.
During the fourth quarter 2020, IAMGOLD executed zero cost collar option contracts based on the Brent benchmark, in the range of $40.70 to $55.00 per barrel, for the period January 2023 to September 2024 to hedge attributable fuel consumption related to mining operations at Essakane. IAMGOLD also executed zero cost collar option contracts relating to the West Texas Intermediate (“WTI”) benchmark, in the range of $31.15 to $45.00 per barrel for 2021, and in the range of $36.10 to $50.00 for the period January 2023 to September 2024. These WTI hedges are attributed to fuel consumption related to mining operations at Rosebel.
In the third quarter 2020, IAMGOLD issued a notice to redeem its 7% Senior Notes due 2025 for a total amount of $421.3 million and funded the redemption on September 29, 2020 and the indenture governing the 2025 Notes was satisfied and discharged on this date.
In the third quarter 2020, IAMGOLD announced that it had completed its private offering of $450 million aggregate principal amount of 5.75% Senior Notes (“Notes”) due 2028. IAMGOLD used the net proceeds from the offering of the Notes to fund the redemption of all of its outstanding 7% Senior Notes due 2025 and for general corporate purposes.
The redemption of the 7% Senior Notes and issuance of the 5.75% Senior Notes extended the term by three and a half years at a lower rate of interest. The refinancing further supports the balance sheet and helps mitigate the risk of gold price volatility and exposure. The redemption also resulted in a cash loss of $21.3 million that is expected to be offset by lower interest expense over the original term of the 7% Notes.
Following the new Notes issuance, both Moody’s and S&P re-affirmed their ratings of B1 and B+, respectively, for IAMGOLD.
In the third quarter 2020, an ESG assessment by Moody’s affiliate Vigeo Eiris ranked IAMGOLD 4th out of 45 sector peers, with notable strengths in community involvement, environmental strategy, health & safety and governance.
In the first quarter 2020, IAMGOLD amended its $500 million credit facility with a maturity date of January 31, 2023. IAMGOLD further amended its credit facility on September 30, 2020. These amendments included, among other things, extending $472 million of credit available under the credit facility agreement to a maturity date of January 31, 2024.

Exploration

In the third quarter 2020, IAMGOLD reported assay results from its 2020 drilling program at the Monster Lake Project in Canada. Drilling highlights included: 3.8 metres grading 16.9 g/t Au, 2.82 metres grading 5.63 g/t Au, and 12.3 metres grading 2.09 g/t Au.
In the second quarter 2020, IAMGOLD reported assay results from its 2020 diamond drilling program at the Rouyn Gold Project in Canada. Drilling highlights included: 9.8 metres grading 10.4 g/t Au and 9.8 metres grading 27.8 g/t Au (including 4.4 metres grading 58.4 g/t Au). IAMGOLD reported additional assay results in the third quarter 2020. Drilling highlights included: 4.1 metres grading 10.4 g/t Au and 7.4 metres grading 8.3 g/t Au.
In the second quarter 2020, IAMGOLD reported initial assay results from its 2020 infill and expansion diamond drilling program at the Nelligan Project in Canada. Drilling highlights included: 25.1 metres grading 1.87 g/t Au and 27.0 metres grading 2.86 g/t Au. IAMGOLD reported additional assay results in the third quarter 2020. Drilling highlights included: 39.1 metres grading 2.14 g/t Au and 34.5 metres grading 1.85 g/t Au. IAMGOLD reported the remaining assay results in the fourth quarter 2020. Drilling highlights included: 17.3 metres grading 7.62 g/t Au and 42.0 metres grading 1.15 g/t Au.

Development and Operations

On November 2, 2020, IAMGOLD reported that a seismic event occurred at Westwood on October 30, 2020. All employees were brought safely above ground. The appropriate government authorities were notified and the cause of the seismic event is being investigated. Milling operations restarted on November 4, 2020 to process stockpile material and Grand Duc open pit ore. The Westwood underground mine operations were suspended pending the results of the investigation and while a business recovery plan was being assessed.
In the third quarter 2020, prior to the seismic event, IAMGOLD filed a National Instrument (“NI”) 43-101 Technical Report for the Westwood mine, incorporating modified mining methods, operational practices and revised productivity assumptions. In this context, total attributable mineral reserves at year end decreased by 47% to 0.626 million ounces, primarily the result of more conservative geotechnical assumptions related to specific zones located in higher seismic risk areas. Overall mineral resources at year end have remained largely unchanged. As is typical for underground operations, and supported by reasonable assumptions in-line with historical operating experience, IAMGOLD continues to work on converting its significant underground mineral resources to mineral reserves over time.
In the third quarter 2020, IAMGOLD, together with joint venture partner Sumitomo Metal Mining Co., Ltd. (“SMM”) announced the decision to proceed with the construction of the Côté Gold Project. During the fourth quarter 2020, activities related to the construction of the Project continued with all key permits required for currently planned construction in place. Additional permits are required to complete subsequent construction elements and commissioning for operations, which IAMGOLD expects to receive in due course. At December 31, 2020, detailed engineering reached 73%, which has enabled IAMGOLD to obtain firm bids and secure prices on all major equipment. As a result, approximately 45% of total expenditures from July 1, 2020 have been committed, further reducing technical and cost risks for the Project. Earthwork contractors also mobilized to site ahead of schedule and commenced work including pad preparation, road widening, and overburden stripping. Camp construction progressed with two additional dormitories in place in January 2021, allowing further ramp up at site.
In the second quarter 2020, Rosebel Gold Mines N.V. (“Rosebel”) signed an Unincorporated Joint Venture (“Rosebel UJV”) agreement with Staatsolie Maatschappij Suriname N.V. (“Staatsolie”) relating to the concession areas within the Rosebel UJV Area of Interest, which includes Saramacca. The Rosebel UJV excludes the existing gross Rosebel mining concession, which is 95% owned by Rosebel and 5% owned by the Republic of Suriname. Rosebel holds a 70% participating interest and Staatsolie holds a 30% participating interest in the Rosebel UJV on behalf of the Republic of Suriname. Staatsolie has paid Rosebel an initial amount of $34.0 million toward an aggregate owing of $54.9 million for all operating and capital expenses related to the Saramacca Project. The remaining amount will be paid out of Staatsolie’s gold entitlement from the Saramacca property.
In the first quarter 2020, IAMGOLD announced that the Government of the Republic of Senegal approved the mining permit application for the Boto Gold Project for an initial 20-year period. The receipt of the mining permit positions the Project for an eventual construction decision and production.

Organizational and Board of Directors Changes

In the fourth quarter 2020, IAMGOLD announced the appointment of Anne Marie Toutant and Deborah Starkman as independent non-executive Directors to IAMGOLD’s Board of Directors, effective December 14, 2020.
In the third quarter 2020, IAMGOLD announced the retirement of Carol Banducci, EVP and CFO, effective March 31, 2021 and the retirement of Jeffery Snow, General Counsel and SVP Business Development, effective August 31, 2020.

In the first quarter 2020, Oumar Toguyeni was appointed to the role of Senior Vice President, International Affairs & Sustainability, with the primary objective of managing IAMGOLD’s relationships with governments and other stakeholders in West Africa and South America.

Reserves and Resources

Total attributable proven and probable gold reserves decreased by 2.8 million ounces or 17% to 13.9 million ounces from the prior year. The decrease was primarily due to the sale of Sadiola, mine depletion at all operations and the previously announced reclassification of a portion of reserves at Westwood (see news release dated August 5, 2020). Excluding the sale of Sadiola, a discontinued operation, total attributable proven and probable reserves decreased by 1.2 million ounces or 7%.
Total attributable measured and indicated resources decreased by 12% to 23.9 million ounces, as a result of the sale of Sadiola and the Eastern Borosi Project, and mine depletion. Total attributable inferred resources decreased by 6% to 11.3 million ounces primarily as a result of the asset sales mentioned above.

Subsequent to Year End

On January 4, 2021, IAMGOLD announced it has adopted new governance guidelines with respect to board renewal to reflect evolving governance best practices. The guidelines provide that: the average Board tenure should not exceed ten years, no director should chair a standing committee of the Board for more than ten years and no director should be the Board Chair for more than ten years. In addition, IAMGOLD announced that John Caldwell voluntarily decided to step down from the Board, effective January 4, 2021, and Mahendra Naik decided not to stand for re-election at the upcoming meeting of shareholders. Ron Gagel was appointed as Chair of the Audit and Finance Committee.
On January 12, 2021, IAMGOLD entered into an agreement to sell a royalty portfolio to Triple Flag Precious Metals Corp for up to $47.6 million. The royalty portfolio includes up to 39 royalties on various non-core exploration and development properties. The transaction has not been completed and is subject to customary closing conditions, a minimum value condition and, in certain instances, rights of first refusal. The transaction is expected to close during the first quarter 2021.
On January 21, 2021, IAMGOLD reported initial assay results from its delineation drilling program at the Gosselin Zone discovery in Canada. Drilling highlights included: 417.3 metres grading 0.95 g/t Au (including 197.2 metres grading 1.60 g/t Au), 353.0 metres grading 1.04 g/t Au (including 46.0 metres grading 3.39 g/t Au) and 86.0 metres grading 5.57 g/t Au (including 30.35 metres grading 14.70 g/t Au).
Subsequent to year end, IAMGOLD added gold hedges for the first half of 2023 with a collar option at strike prices between $1,700 and $2,700 per ounce on 24,000 ounces, for which a premium of $1.1 million was paid.
On February 12, 2021, IAMGOLD further amended the $500 million credit facility to primarily, among other things, extend the maturity date by two years to January 31, 2025 for $490 million of the available credit.
In January 2021, Bloomberg re-iterated IAMGOLD’s inclusion in the 2021 Bloomberg Gender-Equality Index (“GEI”) for the 3rd consecutive year. The 2021 Bloomberg GEI recognizes 380 global companies that foster a more inclusive and equitable workplace.
IAMGOLD ranked 10th out of 116 global mining peers based on the Corporate Knights 2021 Global 100 Sustainability scorecard. Corporate Knights reviews over 8,000 global, publicly traded companies with greater than $1 billion in annual revenues.

UPCOMING GROWTH CATALYSTS

In North America, IAMGOLD is advancing construction of the Côté Gold Project, with the early commencement of major earthworks and the continued expansion of the construction camp. In 2021, approximately 17,000 metres of diamond drilling is planned, including 14,500 metres to continue the delineation drilling program on the Gosselin zone to support the completion of a maiden resource estimate, expected in the second half of 2021. IAMGOLD continues to advance various ongoing and planned delineation and resource evaluation drilling programs at selected projects including the Nelligan Gold, Monster Lake and Rouyn Gold projects in Quebec. At Westwood, work is being done to evaluate the potential development of the Fayolle deposit, which, pending permitting, may provide incremental feed commencing in the fourth quarter 2022 to the Westwood mill as part of its “hub-and-spoke” model. This model exploits the significant mill capacity available at Westwood to bring forward regional exploration value from assets like Fayolle and the optioned Rouyn Gold Project and to enhance the overall value of Westwood with incremental production growth from such supplementary feed.
In West Africa, the Mill Upgrade Project at Essakane is expected to be completed in the first quarter 2021. IAMGOLD continues de-risking activities at the Boto Gold Project, by advancing engineering, building access infrastructure, and progressing with environmental and social programs to support the project development. Building on its exploration success along the Senegal-Mali Shear Zone with several other discoveries located within 15 kilometres of the Boto Gold Project in adjacent countries, IAMGOLD has also initiated a strategic study, referred to as the “Bambouk Gold Complex,” to advance resource evaluation and delineation at the Diakha-Siribaya and Karita projects to support the evaluation of various potential development scenarios and identify regional synergies.
In South America, Rosebel’s camp expansion is expected to be completed by the second quarter 2021, enabling Rosebel to return to full mining rates. Remaining non-critical Saramacca infrastructure is expected to be completed by mid-year.

FULL YEAR AND FOURTH QUARTER 2020 SUMMARY

Financial Performance

Revenues from continuing operations for 2020 were $1,241.7 million, up $176.4 million or 17% from the prior year. The increase was primarily due to higher realized gold prices ($265.6 million), partially offset by lower sales volume at Rosebel ($52.1 million), Essakane ($20.4 million) and Westwood ($17.4 million). Revenues from continuing operations for the fourth quarter 2020 were $347.5 million, up $54.1 million or 18% from the same prior year period. The increase was primarily due to higher realized gold prices ($71.9 million) and higher sales volume at Essakane ($8.1 million), partially offset by lower sales volume at Westwood ($19.3 million) and Rosebel ($6.4 million).
Cost of sales from continuing operations for 2020 was $991.4 million, down $4.3 million from the prior year. The decrease was due to lower depreciation expense ($18.4 million), partially offset by higher royalties ($10.6 million) resulting from higher realized gold prices and higher operating costs ($3.5 million). Cost of sales from continuing operations for the fourth quarter 2020 was $263.5 million, up $11.2 million or 4% from the same prior year period due to higher operating costs ($11.2 million) and royalties ($3.3 million), partially offset by lower depreciation expense ($3.3 million). Operating costs increased due to higher drawdowns of stockpiles compared to the reversal of previous impairments of ore stockpiles at Essakane and Rosebel in the fourth quarter 2019. The higher operating costs were partially offset by reduced costs at Westwood as the underground mine was put into care and maintenance following the seismic event. The increase in royalties was driven by higher realized gold prices.
Depreciation expense from continuing operations for 2020 was $256.7 million, down $18.4 million or 7% from the prior year. The decrease was primarily due to lower depreciation at Westwood resulting from the extended life of the underground blocks and impairment charge recorded in the fourth quarter 2019. Depreciation expense from continuing operations for the fourth quarter 2020 was $69.6 million, down $3.3 million or 5% from the same prior year period due to the same factor as the annual decrease partially offset by higher depreciation related to stockpiles.
Income tax expense for 2020 was $44.1 million, up $13.7 million from the prior year. Income tax expense for 2020 comprised current income tax expense of $55.8 million (December 31, 2019 – $38.3 million) and deferred income tax recovery of $11.7 million (December 31, 2019 – deferred income tax recovery of $7.9 million). The increase in income tax expense was primarily due to changes to deferred income tax assets and liabilities, differences in the impact of fluctuations in foreign exchange, and differences in the level of taxable income in IAMGOLD’s operating jurisdictions from one period to the next.
Net earnings from continuing operations attributable to equity holders for 2020 was $38.5 million, or $0.08 per share, compared to net loss from continuing operations of $373.3 million, or $0.80 per share in the prior year. The increase in net earnings was primarily due to lower impairment charges, net of reversal ($333.6 million) and higher gross profit ($180.7 million), partially offset by lower interest income, derivatives and other investment gains (losses) ($53.0 million), higher other expenses ($32.6 million) and higher income tax expense ($13.7 million). Net earnings from continuing operations attributable to equity holders for the fourth quarter 2020 was $59.0 million, or $0.12 per share, compared to net loss from continuing operations of $303.8 million, or $0.65 per share from the same prior year period. The increase in net earnings was primarily due to lower impairment charges, net of reversal ($321.1 million) and higher gross profit ($42.9 million).
Adjusted net earnings from continuing operations attributable to equity holders² was $87.7 million, or $0.19 per share², compared to adjusted net loss from continuing operations²of $30.0 million, or $0.06 per share² in the prior year. Adjusted net earnings from continuing operations attributable to equity holders² for the fourth quarter 2020 was $19.1 million, or $0.04 per share², compared to adjusted net loss from continuing operations²of $3.8 million, or $0.01 per share² in the same prior year period.
Net cash from operating activities for 2020 was $347.6 million, down $15.4 million from the prior year. The decrease was primarily due to proceeds received in the prior year from the forward gold sale arrangement ($169.8 million), settlement of derivatives ($17.9 million) and higher movements in non-cash working capital items and non-current ore stockpiles ($16.0 million), partially offset by higher earnings after non-cash adjustments ($189.4 million). Net cash from operating activities for the fourth quarter 2020 was $128.7 million, down $133.8 million from the same prior year period. The decrease was primarily due to proceeds received in the prior year from the forward gold sale arrangement ($169.8 million) and lower movements in non-cash working capital items and non-current ore stockpiles ($15.6 million), partially offset by higher earnings after non-cash adjustments ($54.5 million).
Net cash from operating activities before changes in working capital²for 2020 was $368.1 million, up $0.6 million from the prior year. Net cash from operating activities before changes in working capital²for the fourth quarter 2020 was $108.0 million, down $118.2 million from the same prior year period.
Mine-site free cash flow² for 2020 was $223.2 million, up $164.5 million from the prior year. Mine-site free cash flow² for the fourth quarter 2020 was $77.7 million, up $22.6 million from the same prior year period.

Financial Position

Cash, cash equivalents, short-term investments and restricted cash were $986.1 million at December 31, 2020, up $121.3 million from December 31, 2019. The increase was primarily due to cash generated from operating activities ($347.6 million), net proceeds from the sale of a 30% interest in the Saramacca Project ($34.0 million) and net proceeds from the sale of Sadiola ($25.0 million), partially offset by spending on property, plant and equipment ($292.1 million).

Production and Costs

Attributable gold production from continuing operations was 653,000 ounces for 2020, down 57,000 ounces from the prior year. The decrease was primarily due to lower throughput at Rosebel (41,000 ounces) resulting from a temporary labour disruption between June 12 and July 24, 2020, the underground mine at Westwood being placed on care and maintenance due to the seismic event in the fourth quarter and the government mandated province-wide COVID-19 related shutdown between March 15 and April 15, 2020 (12,000 ounces), and lower throughput at Essakane resulting from COVID-19 related restrictions (4,000 ounces). Attributable gold production from continuing operations was 169,000 ounces for the fourth quarter 2020, down 10,000 ounces from the same prior year period. The decrease was due to the seismic event at Westwood (15,000 ounces), lower throughput at Rosebel (4,000 ounces), partially offset by higher head grades at Essakane (9,000 ounces) due to mine sequencing.
Attributable gold sales from continuing operations were 646,000 ounces for 2020, down 61,000 ounces from the prior year. The decrease was due to lower sales volume at Rosebel (35,000 ounces), Westwood (13,000 ounces), and Essakane (13,000 ounces). Attributable gold sales from continuing operations were 172,000 ounces for the fourth quarter 2020, down 12,000 ounces from the same prior year period. The decrease was due to lower sales volume at Westwood (14,000 ounces) and Rosebel (4,000 ounces), partially offset by higher sales volume at Essakane (6,000 ounces).
Cost of sales¹ per ounce from continuing operations for the fourth quarter and year ended 2020 of $1,045 and $1,057, respectively, were up 15% and 11% from the same prior year periods primarily due to lower sales volume in addition to the factors noted above.
Total cash costs²per ounce produced from continuing operations for the fourth quarter and year ended 2020 of $998 and $984, respectively, were up 6% and 8% from the same prior year periods due to lower production and factors noted above.
All-in sustaining costs² per ounce sold from continuing operations for the fourth quarter 2020 was $1,294, up 10% from the same prior year period due to higher cost of sales¹ per ounce. All-in sustaining costs² per ounce sold from continuing operations for the year ended 2020 was $1,232, up 8% from the prior year due to higher cost of sales¹ per ounce, partially offset by lower sustaining capital expenditures.

Continued Commitment to Zero Harm®

In 2020, IAMGOLD’s global safety statistics show a 10% improvement from 2019 in the DART³ (days away, restricted, transferred duty) frequency rate, and a 23% improvement in the TRI (total recordable injuries) frequency rate. Through various programming, IAMGOLD continuously promotes a safe work environment.

Global COVID-19 Pandemic

In response to the global COVID-19 pandemic, IAMGOLD has taken extensive steps to protect the health and safety of employees and contractors.
As the global COVID-19 pandemic evolved, IAMGOLD adjusted and expanded the extensive measures previously implemented to protect the health and safety of employees, contractors and local communities. These measures included training on new procedures and sanitary measures recommended by Health Authorities, adjusted work schedules, physical distancing and protective equipment, restricted site access, screening processes for employees, contractors and incoming supplies, use of thermal cameras to check temperatures before site entrance, and arranging additional transportation buses and on-site medical personnel. In addition, the number of living quarters at Essakane and Rosebel were increased. Initially the on-site workforce was limited to essential personnel only. As IAMGOLD’s COVID-19 health and safety protocols were embedded in the operations, the workforce was expanded with Essakane reaching normal capacity in the third quarter 2020 and Rosebel expected to reach normal capacity in the first quarter 2021.

GOLD PRODUCTION, COST OF SALES, TOTAL CASH COSTS AND ALL-IN SUSTAINING COSTS

IAMGOLD expects 2021 attributable gold production to be in the range of 630,000 to 700,000 ounces. At Essakane, production is expected to be between 365,000 and 390,000 ounces, improving from 2020 levels, with increased recoveries and throughput anticipated benefiting from targeted mill improvements. At Rosebel, production is expected to be between 220,000 and 245,000 ounces, increasing from 2020 levels as the mining operations resume their operating cadence resulting in increased mill throughput with higher grade feed. Westwood production is expected to be between 45,000 to 65,000 ounces, below 2020 levels, with continuous mill feed supplied by the Grand Duc open pit near the mill complex and a stronger second half, which is expected to benefit from the safe restart of underground operations.

IAMGOLD expects cost of sales¹ on an attributable ounce sold basis to be in the range of $980 to $1,030. IAMGOLD’s guidance on total cash costs² and all-in sustaining costs² for 2021 is expected to be in the range of $930 to $980 per ounce produced and $1,230 and $1,280 per ounce sold, respectively. All-in sustaining cost guidance for 2021 reflects ongoing efforts to improve productivity and optimize performance across the sites, while safeguarding operations from any resurgent impacts of the global COVID-19 pandemic. The guidance IAMGOLD provides is annual and quarterly variation is normal. Costs are expected to be lower in the second half of the year compared to the first half, benefitting from higher anticipated production in the second half. The guidance also considers the impact of IAMGOLD’s assumptions related to oil prices and foreign exchange rates as outlined in the Market Trends section.

ESSAKANE

IAMGOLD expects attributable production at Essakane in 2021 to be in the range of 365,000 to 390,000 ounces. Essakane expects to continue to optimize mining activity, lower unit costs and pursue mine and mill efficiencies as higher proportions of hard rock are processed.

Mining activity is expected to achieve elevated levels in 2021 supported through the use of a mining contractor to secure strategic pushback objectives providing greater access to higher grade ore zones. Essakane is also targeting improvements to the mine hauling fleet through upgrades that increase unit payloads and overall truck utilization. Maintenance activities are expected to sustain the improvements that have been realized in overall truck fleet availability and reliability, as well as increasing the drill fleet reliability.

Essakane is targeting completion of the mill upgrade in the first half of 2021 with improvements expected to de-bottleneck the crushing circuit which is expected to yield higher grinding capacities increasing overall throughput in addition to optimizing liner and grate configurations. Essakane expects to continue to realize improvements in gravity recoveries from the addition of a third gravity screen to mitigate any adverse effects encountered from ore pockets containing graphitic carbon.

These initiatives are designed to deliver on the 2021 production and cost targets, while positioning Essakane to pursue the evaluation of additional resources at satellite zones with the potential to add to the mine life of the Essakane operation.

ROSEBEL

IAMGOLD expects attributable production at Rosebel in 2021 to be in the range of 220,000 to 245,000 ounces. 2021 production guidance reflects the resumption of strategic pushbacks and mine development on the Rosebel concession, which were paused in 2020. These activities are intended to expose higher grade ore zones, while mining volumes at the Saramacca deposit continue to ramp up into higher grade zones. Cycle times are expected to be optimized along the newly completed haul road linking the Saramacca deposit to the Rosebel mill. While the Rosebel mining operations return to normal operating levels, the mill feed is expected to be supplemented through the processing of available ore stockpiles.

Mill throughput is expected to return to normal operating levels in 2021 reflecting continuous mining activities in the year, with head grades reflective of higher grade material sourced from the Saramacca deposit. Hard rock run rates are targeted to increase in 2021 through improvements in both blast fragmentation and crusher performance. Additional improvements to the mill are planned including replacements in the process water piping network to improve throughput, as well as upgrades to the elution circuit designed to reduce liquid losses and improve mill recoveries.

WESTWOOD

IAMGOLD expects production at Westwood in 2021 to be in the range of 45,000 to 60,000 ounces benefitting from the safe restart of underground extraction activities expected in the second half of the year. Throughout 2021 the mill feed will be supplemented with lower grade surface material from the Grand Duc satellite pit nearby the mill complex.

INCOME TAXES

IAMGOLD expects to pay cash taxes in the range of $78 million to $88 million in 2021. In that regard, total cash taxes in 2021 include an estimated additional $8 million of tax to be paid by Rosebel, pursuant to a temporary 10% Government of Suriname “Solidarity Levy”, due to expire December 31, 2021, for which the Rosebel tax stability agreement only serves to reduce the extra levy from 10% to 9%, making the rate of tax for Rosebel 45% instead of 36% for the period February 1 through December 31, 2021. IAMGOLD is subject to income tax in several jurisdictions, at various tax rates. However, the consolidated effective tax rate for IAMGOLD is subject to significant fluctuations period over period due to: expenditures and revenues recognized only for financial accounting purposes or only for income tax purposes; income tax unrelated to the income or loss before taxes for the current period, such as withholding taxes; and adjustments for deferred tax purposes that are not directly related to the income or loss before taxes for the current period, such as foreign exchange rate changes. In addition, adjustments to deferred income tax assets and/or liabilities may be recorded during the year.

DEPRECIATION EXPENSE

Depreciation expense in 2021 is expected to be in the range of $295 million to $305 million.

5 In addition to the above capital expenditures, $23 million in total principal lease payments are expected.

In 2021, IAMGOLD expects capital spending to be $710 million ± 5%. The increase in spending over 2020 reflects Côté construction spending primarily focused on major earthworks and infrastructure, expected higher capitalized stripping at both Essakane and Rosebel as a result of COVID-19 related impacts in 2020 on life-of-mine pit sequencing and Boto de-risking activities.

Sustaining

Sustaining capital guidance of $120 million and is expected to be higher than the amount expended in 2020. Total sustaining capitalized stripping of $10 million is included in sustaining capital and is also expected to be higher than in 2020. Both increases reflect re-sequencing of activities from 2020.

Non-sustaining (Development/Expansion)

Rosebel’s non-sustaining capital of $75 million includes the completion of non-critical path items related to Saramacca construction, targeted for completion in the first half of 2021, and non-sustaining capitalized stripping of $45 million. Essakane’s non-sustaining capital of $90 million primarily comprises $65 million in capitalized stripping for future production, tailings liners, village resettlement activities and the completion of the mill optimization project, targeted for completion in the second quarter 2021. Westwood’s non-sustaining capital of $10 million is primarily for underground development.

OPERATIONS ANALYSIS BY MINE SITE

Essakane Mine – Burkina Faso (IAMGOLD interest – 90%)

Attributable gold production for the fourth quarter was higher by 10% compared to the same prior year period, primarily due to the focus on mining in higher grade zones which was partially offset by lower recoveries resulting from the higher graphitic content of the ore. Attributable gold production for the year ended 2020 was lower by 1% compared to the same prior year period, primarily due to lower mill throughput from processing higher quantities of harder rock and lower recoveries, partially offset by higher grades.

Material mined in the fourth quarter was lower compared to the same prior year period due to changes in mine sequencing which led to higher waste mining in upper areas of the pit and lower ore mining at the bottom of the pit. Material mined during the year ended 2020 was slightly lower compared to the same prior year period as fewer mining crews were available resulting from COVID-19 restrictions. Although the Mill Upgrade Project (the “Mill Upgrade”) was impacted by delays in fabrication and international delivery schedules resulting from the global COVID-19 pandemic, all required equipment arrived onsite and the installation commenced in the fourth quarter. The Mill Upgrade is scheduled to be completed in the first quarter 2021.

Essakane implemented strict COVID-19 protocols to ensure the health and safety of employees, including social distancing, hand washing stations, the mandatory use of masks on site and in the offices in Ouagadougou, modifications to work rotations, the use of rapid antigen tests on employees entering the site and the quarantining of all positive and suspected cases. Additional measures included reconfiguration of site facilities to accommodate physical distancing rules, 24/7 ambulance service and air evacuation plans for emergency situations. As these protocols were embedded in the operations, Essakane progressively reached normal capacity in the third quarter 2020. A project to add 200 beds was completed in the third quarter for alignment with the COVID-19 protocols. In addition, a 20-bed field hospital and a medical confinement house were established in Ougadougou to accommodate COVID-19 cases.

As well, detailed safety procedures were developed, communication channels were created for questions and concerns, and regular inspections were conducted by internal site health professionals and by the local health authorities to ensure these measures were appropriately implemented and consistently followed.

Cost of sales per ounce sold for the fourth quarter and year ended 2020 were higher by 29% and 16%, respectively, compared to the same prior year periods primarily due to higher operating costs resulting from additional drawdowns of stockpiles to feed the mill, increased cyanide consumption to accommodate changing ore characteristics and higher royalties driven by higher realized gold prices.

Total cash costs per ounce produced for the fourth quarter and year ended 2020 were higher by 9% and 7%, respectively, compared to the same prior year periods. As noted above, this was primarily due to higher operating costs and higher royalties.

All-in sustaining costs per ounce sold for the fourth quarter 2020 were higher by 15% compared to the same prior year period, primarily due to increased cost of sales per ounce and increased sustaining capital expenditures for mobile equipment. All-in sustaining costs per ounce sold for the year ended 2020 were higher by 7%, compared to the same prior year period, primarily due to increased cost of sales per ounce partially offset by lower sustaining capital expenditures.

Sustaining capital expenditures for the fourth quarter 2020 of $16.7 million included mobile equipment of $7.0 million, capital spares of $3.2 million, camp safety & security of $2.1 million, power generator overhaul of $1.6 million, mill enhancements of $0.4 million, resource development of $0.1 million, and various other sustaining capital expenditures of $2.3 million. Non-sustaining capital expenditures of $20.7 million included capitalized stripping of $15.6 million, tailings liners and dams of $3.3 million, mill upgrade of $1.0 million and various other non-sustaining capital expenditures of $0.8 million.

Sustaining capital expenditures for the year ended 2020 of $37.3 million included capital spares of $11.4 million, mobile equipment of $7.9 million, camp safety and security improvements of $4.6 million, mill enhancements of $3.3 million, power generator overhaul of $2.4 million, resource development of $1.4 million, and various other sustaining capital expenditures of $6.3 million. Non sustaining capital expenditures for the year ended 2020 of $76.4 million included capitalized stripping of $57.8 million, tailings liners and dams of $11.9 million, mill upgrade of $4.6 million, camp extension of $1.3 million, and other non-sustaining capital expenditures of $0.8 million.

Outlook

Essakane’s attributable production in 2021 is expected to be between 365,000 and 390,000 ounces. Capital expenditures are expected to be approximately $150 million, comprising $60 million of sustaining capital expenditures and $90 million of non-sustaining capital expenditures. Sustaining capital of $60 million includes capitalized stripping ($10 million), capital spares ($14 million), mobile equipment ($10 million), major rebuilds & repairs ($5 million), generator overhaul ($3 million), mill equipment ($3 million), resource development ($2 million), and other sustaining capital expenditures ($13 million). Non-sustaining capital of $90 million includes expansionary capitalized stripping ($65 million), tailings liners ($11 million), village resettlement activities ($8 million), the tailings thickening plant ($3 million) and mill upgrades ($3 million).

Rosebel Mine – Suriname (IAMGOLD interest – 95%)

Attributable gold production for the fourth quarter was lower by 7% compared to the same prior year period primarily due to lower throughput resulting from unplanned mill maintenance to reline the ball mills. This decrease was partially offset by higher grades as a result of mining at the Saramacca deposit delivering 1.36 million tonnes of ore at a grade of 1.14 g/t Au.

Attributable gold production for the year ended 2020 was lower by 16%, compared to the same prior year period primarily due to the temporary work stoppage from June 12 to July 24, 2020. This decrease was partially offset by higher grades from mining at the Saramacca deposit delivering a total of 2.35 million tonnes of ore at a grade of 1.27 g/t Au.

The Saramacca haul road was completed in the fourth quarter. The project to increase camp capacity, to meet newly implemented social distancing requirements, is underway as all modules arrived on site during the quarter and are being assembled.

Additional non-critical Saramacca infrastructure will be completed in the first half of 2021.

Rosebel implemented strict COVID-19 protocols to ensure the health and safety of employees, including social distancing, the mandatory use of masks in public places or where social distancing is not possible, modifications to work rotations, the use of rapid antigen tests on 40% of employees entering the site and all contact cases and symptomatic cases on site were isolated in separate designated blocs. Confirmed cases at site were transported to Paramaribo for isolation and treatment in government medical facilities. As these protocols were embedded in the operations, the workforce recall was expanded with Rosebel operating at 75% of mining capacity by the end of the fourth quarter 2020. To accommodate the full workforce under the COVID-19 protocols, a project is underway that is expected to add an additional 300 beds by the second quarter 2021. The Mill was operating at its normal rate by the end of July with ore sourced primarily from stockpiles. Mine direct feed is planned to increase with the augmented manpower on site by the second quarter 2021. And Saramacca achieved planned mining rates in the fourth quarter.

The collective labour agreement with the Rosebel Union expired on August 15, 2020. Negotiations for a new agreement continue to progress.

Cost of sales per ounce sold and total cash costs per ounce produced for the fourth quarter were higher by 2% and 5% respectively, compared to the same prior year periods, primarily due to lower sales and production volumes, and higher royalties driven by higher realized gold prices. Cost of sales per ounce sold and total cash costs per ounce produced for the year ended 2020 were both higher compared to the prior year by 6%. This was primarily due to the reduction in sales and production volumes resulting from the temporary work stoppage from June 12 to July 24, 2020 related to the introduction of COVID-19 safety protocols, as well as higher royalties, resulting from higher realized gold prices

All-in sustaining costs per ounce sold for the fourth quarter 2020 were consistent with the same prior year period. All-in sustaining costs per ounce sold for the year ended 2020 were higher by 5% primarily due to higher cost of sales per ounce, partially offset by lower sustaining capital expenditures.

Sustaining capital expenditures for the fourth quarter 2020 of $8.1 million included resource development of $2.4 million, capital spares of $1.9 million, building upgrades of $0.7 million, mill enhancements of $0.7 million, tailings management of $0.4 million, mobile equipment of $0.4 million and various other sustaining capital expenditures of $1.6 million. Non-sustaining capital expenditures for the fourth quarter 2020 of $12.3 million included capitalized stripping of $7.3 million, $4.5 million related to the Saramacca Project and $0.5 million for the camp capacity expansion.

Sustaining capital expenditures for the year ended 2020 of $29.3 million included capital spares of $10.9 million, resource development of $4.6 million, mill equipment of $3.3 million, building upgrades of $2.7 million, tailings management of $1.9 million, mobile equipment of $1.0 million and various other sustaining capital expenditures of $4.9 million. Non-sustaining capital expenditures for the year ended 2020 of $38.5 million included $22.6 million related to the Saramacca Project, $14.9 million of capitalized stripping and $1.0 million for the camp capacity expansion. The Saramacca Project costs of $22.6 million were related to haul road, bridge and other infrastructure construction, and associated costs of vehicles and mobile equipment.

Outlook

Rosebel’s attributable production in 2021 is expected to be between 220,000 and 245,000 ounces. Capital expenditures are expected to be approximately $125 million, comprising $50 million of sustaining and $75 million of non-sustaining capital. Sustaining capital of $50 million includes capital spares ($23 million), mill upgrades ($8 million), resource development ($6 million), tailings management ($5 million), water management ($3 million), mobile equipment ($3 million), and other small projects ($2 million). Non-sustaining capital of $75 million is to secure strategic expansionary pushbacks within the Rosebel concession ($45 million) including accompanying pit infrastructure ($6 million) and the completion of infrastructure and civil works on the Saramacca property ($24 million).

Westwood Mine – Canada (IAMGOLD interest – 100%)

On November 23, 2020, IAMGOLD announced a temporary reduction in the underground workforce of approximately 70% at the Westwood mine, as the underground operations were placed in care and maintenance following the seismic event on October 30, 2020. As reported on November 2, 2020, the cause of the seismic event is under investigation while a business recovery plan for Westwood is being assessed. The Westwood mill restarted on November 4, 2020, processing stockpile material and Grand Duc open pit ore.

Despite the underground operation suspension, the permitting process, environmental studies and sampling have commenced on the Fayolle property, which was acquired in the second quarter.

Gold production for the fourth quarter and the year ended 2020 was 52% and 13% lower, respectively, primarily due to the underground mine being put into care and maintenance. Despite the challenges faced by Westwood, the additional ore sourced from Grand Duc resulted in the highest annual mill throughput performance since 2005.

Cost of sales per ounce sold and total cash costs per ounce produced for the fourth quarter were higher by 6% and 1% respectively, compared to the same prior year period, primarily due to lower sales and production volumes that were partially offset by lower operating costs as the underground mine was placed in care and maintenance in the fourth quarter 2020. Cost of sales per ounce sold and total cash costs per ounce produced for the year ended 2020 were higher compared to the prior year by 11% and 23%, respectively. This was primarily due to the reduction in sales and production volumes.

All-in sustaining costs per ounce sold for the fourth quarter and year ended 2020 were higher compared to the same prior year period by 9% and 19% respectively, primarily due to higher cost of sales per ounce partially offset by lower sustaining capital expenditures as a result of COVID-19 restrictions and the underground mine suspension.

Sustaining capital expenditures for the fourth quarter 2020 of $2.1 million included deferred development of $0.9 million, underground construction of $0.5 million, underground fixed equipment of $0.3 million, mobile equipment of $0.1 million and various other sustaining capital expenditures of $0.3 million. Non-sustaining capital expenditures for the fourth quarter 2020 of $1.9 million included deferred development of $0.9 million, fixed and mill equipment of $0.4 million, underground construction of $0.1 million, development drilling of $0.1 million and various other non-sustaining capital expenditures of $0.4 million.

Sustaining capital expenditures for the year ended 2020 of $11.7 million included deferred development of $7.0 million, underground fixed equipment of $2.3 million, underground construction of $1.7 million, mobile equipment of $0.2 million, and various other sustaining capital expenditures of $0.5 million. Non-sustaining capital expenditures for the year ended 2020 of $9.5 million included deferred development of $5.7 million, development drilling of $1.4 million, underground construction of $0.9 million, fixed and mill equipment of $0.5 million, mobile equipment of $0.3 million, and various other non-sustaining capital expenditures of $0.7 million.

Westwood was placed on care and maintenance on March 25, 2020, along with other mining companies province-wide, as directed by the Government of Quebec in response to the COVID-19 pandemic as mining was considered a non-essential business. Subsequently on April 15, 2020, Westwood commenced the restart of operations from care and maintenance following the April 13, 2020 confirmation from the Government of Quebec that mining is an essential business. The restart at Westwood was done in accordance with the standards set by the Government of Quebec, the Public Health Directorate and the Commission des normes, de l’équité, de la santé et de la sécurité du travail (“CNESST”) to limit the risk of the spread of COVID-19. Ramp-up activities included training employees on new procedures and sanitary measures, adjusted work schedules and transport, and physical distancing and protective equipment. In addition, site access controls have been enhanced, including temperature checks on all employees and visitors entering the site.

Outlook

Westwood’s production in 2021 is expected to be between 45,000 and 65,000 ounces with underground extraction activities expected to restart in the second half of the year supported by an operational resiliency plan targeting the safe extraction from multiple zones in the mine. Capital expenditures are expected to be approximately $20 million, consisting of $10 million in sustaining and $10 million in non-sustaining capital.

DISCONTINUED OPERATIONS

Mali – Sadiola Mine (IAMGOLD interest – 41%)

On December 30, 2020, IAMGOLD together with its joint venture partner AngloGold Ashanti Limited (“AGA”) completed the sale of their collective interest in Société d’Exploitation des Mines d’Or de Sadiola S.A. (“Sadiola”) to Allied Gold Corp (“Allied Gold”). Upon closing, IAMGOLD and AGA each received $25 million. In addition, on January 4, 2021, IAMGOLD and AGA each received additional consideration of $1.8 million based upon the amount by which the cash balance of Sadiola at April 30, 2020 was greater than the amount agreed pursuant to the agreement entered into by IAMGOLD and AGA with Allied Gold in December 2019. IAMGOLD and AGA remain entitled to deferred consideration of $12.5 million each upon the production of the first 250,000 ounces from the Sadiola Sulphides Project (“SSP”), $12.5 million each upon the production of a further 250,000 ounces from the SSP, and $1.25 million each in the event a favourable settlement is achieved by Sadiola in ongoing litigation pending before the Malian courts.

Mali – Yatela Mine (IAMGOLD interest – 40%)

On February 14, 2019, Sadiola Exploration Limited (“SADEX”), a subsidiary jointly held by IAMGOLD and AGA, entered into a share purchase agreement with the Government of Mali, whereby SADEX agreed to sell to the Government of Mali its 80% participation in Société d’Exploitation des Mines d’Or de Yatela (“Yatela”), for a consideration of $1. The transaction remains subject to the fulfillment of a number of conditions precedent, among which the adoption of two laws, confirming the change of status of Yatela to a State Entity, and also the creation of a dedicated state agency, notably in charge of mine rehabilitation and closure. As part of the transaction, and upon its completion, IAMGOLD will make a one-time payment of approximately $18.5 million to the said state agency, in an amount corresponding to the estimated costs of completing the rehabilitation and closure of the Yatela mine, and also financing certain outstanding social programs. Upon completion and this payment being made, SADEX and its affiliated companies will be released of all obligations relating to the Yatela mine, including those relating to rehabilitation, mine closure and the financing of social programs.

As of March 31, 2019, the Yatela disposal group met the criteria to be classified as held for sale. The Yatela disposal group continues to meet the criteria to be classified as held for sale as IAMGOLD remains confident that the conditions precedent will be fulfilled and the sale will close.

Together the Sadiola and Yatela disposal groups are considered a separate geographical area of operation and have therefore been presented as discontinued operations in the Consolidated statement of earnings (loss).

CONSTRUCTION PROJECTS

Côté Gold Project, Canada

The Côté Gold Project is a 70:30 joint venture between IAMGOLD as the operator, and Sumitomo Metal Mining Co., Ltd. (“SMM”). On July 21, 2020, IAMGOLD, together with SMM, announced the decision to proceed with the construction of the Project, which at a gold price of $1,700, on a 100% basis, is expected to have a net present value of $2.0 billion and an internal rate of return of 22.4% (see news release dated July 21, 2020).

As at December 31, 2020, the Project reported (on a 100% basis) proven and probable mineral reserves of 233.0 million tonnes grading 1.0 g/t Au for 7.3 million contained ounces. Measured and indicated resources (inclusive of reserves) totaled 365.5 million tonnes grading 0.9 g/t Au for 10.2 million contained ounces, and inferred resources totaled 189.6 million tonnes grading 0.6 g/t Au for 3.8 million contained ounces (see news release dated February 17, 2021).

In line with company-wide COVID-19 safety protocols, additional steps have been taken to protect the health and safety of employees and contractors at the Project, including PCR testing of all personnel and visitors entering the site and the mandatory use of masks in vehicles, common areas, or where social distancing is not possible. In addition to PCR testing, IAMGOLD expects to implement antigen testing. Both tests are diagnostic tools intended to reduce the spread of COVID-19 through detection and quarantine as appropriate.

The planned construction schedule is 32 months, with the following key milestones:

Construction start: Q3 2020 – commenced on schedule
Major earthworks start: Q2 2021 – commenced early, in Q1 2021
Process building enclosed: Q1 2022
Tailings Management Facility Phase 1 completed: Q4 2022
Commissioning completed: Q3 2023
Commercial production: H2 2023

IAMGOLD’s total expenditures (exclusive of sunk costs) from July 1, 2020, for its 70% share of the Project construction costs, net of leasing, remain in the range of $875 million to $925 million. IAMGOLD’s share of leasing is expected to be approximately $120 million, assuming a go-forward USDCAD exchange rate of 1.30 (previously approximately $80 million at an exchange rate of 1.35).

Total expenditures are primarily comprised of capital expenditures. Non-capital expenditures represent approximately 4% of the total. Total expenditures are currently expected to be incurred as set out in the table below. The minor changes from year to year reflect the timing of lease arrangements and non-critical path capital expenditures following advancement of detailed engineering and procurement with no impact on the overall Project schedule.

Distribution of Spend

Year	% Total Expenditures
	Original Estimate	Current Estimate
2020: (from July 1)	10%	6%
2021:	45%	41%
2022:	35%	35%
2023:	10%	18%

The Côté Gold Project’s costs are exposed to the Canadian dollar. As at year end and including contracts subsequently executed, IAMGOLD has hedged this exposure using forwards and collar options as follows: for 2021, approximately 44% of this exposure is hedged in the range of USDCAD 1.28 to 1.47. In addition, IAMGOLD has allocated approximately C$145 million of cash on hand to fund the Project which, together with the derivative hedges, increases the percentage of the exposure hedged to approximately 73%. For 2022, approximately 28% of this exposure is hedged in the range of USDCAD 1.30 to 1.48; and for the remaining construction costs related to 2023, approximately 65% of this exposure is hedged in the range of USDCAD 1.30 to 1.46. IAMGOLD will continue to execute hedges for the balance of the Project’s Canadian dollar exposure as appropriate. The Project is also exposed to fuel costs. IAMGOLD has hedged approximately 90% of the entire Project’s fuel exposure with collar options in the range of $33 – $50 per barrel of West Texas Intermediate oil.

During the fourth quarter 2020, activities related to the construction of the Project continued with all key permits required for currently planned construction activities in place. Additional permits are required to complete subsequent construction elements and commissioning for operations, which IAMGOLD expects to receive in due course. At December 31, 2020, detailed engineering reached 73% which has enabled IAMGOLD to obtain firm bids and secure prices on all major equipment. This included the awarding of contracts for the fabrication of long-lead items such as the ball mill and high pressure grinding rolls. As a result, approximately 45% of total expenditures from July 1, 2020 have been committed, further reducing technical and cost risks for the Project.

During the fourth quarter 2020, the earthwork contractors mobilized to site ahead of schedule and commenced work including pad preparation, road widening, and overburden stripping. Camp construction progressed with two additional dormitories in place in January 2021, allowing further ramp up at site. Of the total number of rooms planned, approximately 25% have been installed, meeting the current requirements of the site.

As at December 31, 2020, $51 million of the Project’s planned total expenditures from July 1, 2020 have been incurred.

Capital expenditures	$	38.0	$	6.8	$	4.7	$	73.1	$	31.3	$	17.8

Outlook

The Project initiated earthwork construction in the first quarter 2021, ahead of schedule.

Camp construction to increase the current capacity on site will continue as planned and is expected to be fully commissioned by the second half of 2021. Detailed engineering will continue to advance and procurement will initiate the expediting phase for critical equipment contracts awarded in the fourth quarter 2020.

Total Project expenditures are expected to be $368 million in 2021, including $355 million of capital expenditures.

Greenfield Exploration

In addition to planned delineation drilling programs to support the future mining activities of the Côté deposit itself, IAMGOLD also carries out an ongoing greenfield exploration program on the Côté property. This greenfield exploration is not included in the Project budget.

In the fourth quarter 2020, IAMGOLD spent $0.5 million (2020 – $1.8 million) on greenfield exploration activities which were focused on continued delineation diamond drilling on the newly discovered Gosselin and Young-Shannon zones, located approximately 1.5 kilometres northeast of the Côté gold deposit. Approximately 4,100 metres of diamond drilling were completed during the quarter, for a total of approximately 11,800 metres completed in 2020. Subsequent to the quarter, IAMGOLD reported first assay results from the ongoing delineation drilling program with highlights including: 417.3 metres grading 0.95 g/t Au, including 197.2 metres grading 1.60 g/t Au; 353.0 metres grading 1.04 g/t Au, including 46.0 metres grading 3.39 g/t Au; and 86.0 metres grading 5.57 g/t Au, including 30.35 metres grading 14.70 g/t Au (see news release dated January 21, 2021).

In 2021, IAMGOLD expects to spend $2.8 million on greenfield exploration related to the Côté property. Approximately 17,000 metres of diamond drilling is planned, including 14,500 metres to continue the delineation drilling program on the Gosselin zone to support the completion of a maiden resource estimate, expected in the second half of 2021.

DEVELOPMENT PROJECTS

Boto Gold Project, Senegal

As at December 31, 2020, the Boto Gold Project (on a 100% basis) reported estimated probable mineral reserves totaling 29.0 million tonnes grading 1.7 g/t Au for 1.6 million contained ounces. Indicated resources (inclusive of reserves) totaled 40.6 million tonnes grading 1.6 g/t Au for 2.0 million contained ounces and inferred resources totaled 8.2 million tonnes grading 1.8 g/t Au for 469,000 contained ounces (see news release dated February 17, 2021).

In line with company-wide COVID-19 safety protocols, additional steps have been taken to protect the health and safety of employees and contractors at the Project, the mandatory use of masks in vehicles, common areas, or where social distancing is not possible and thermal screening of all personnel and visitors entering the site.

During the first quarter 2020, IAMGOLD announced that the Government of the Republic of Senegal approved the exploitation permit application for the Boto Gold Project for an initial period of 20 years. With the receipt of the mining permit, the Project is fully permitted and is positioned for a construction decision and eventual production. IAMGOLD also announced the results on various project development and operating optimizations studies undertaken since the completion of the 2018 Feasibility Study and filed a supporting National Instrument 43-101 Technical Report. The optimized study contemplates an operation that is expected to produce an average of 160,000 ounces of gold per year during the first six years of operations, averaging 130,000 ounces of gold per year at all-in sustaining costs of $842 per ounce sold over a mine life of approximately 11 years. With expected initial capital expenditures of $271 million, the study suggests an after-tax net present value (using a 6% discount rate) of $219 million using a gold price assumption of $1,350 per ounce (see news releases dated October 22, 2018, January 13, 2020, and February 14, 2020). The capital cost estimate in the Optimization Study reflects pricing as at the second quarter 2019 and is deemed to have an overall accuracy of ±15%. The Optimization Study estimate excludes escalation, inflation and the impact of project and schedule changes.

During the fourth quarter 2020, Project de-risking activities continued, with project engineering advancing to approximately 70% complete. Activities included commencing road construction, commissioning a construction camp, commencing earthworks for the permanent camp, and awarding engineering contracts related to plant equipment design. Various geotechnical and hydrogeological assessments are currently underway which will be used to refine facility and pit design. Restrictions related to the COVID-19 pandemic eased during the fourth quarter, allowing work on site to progress with the proper controls and processes in place to ensure a safe working environment for all personnel and nearby communities. Capital expenditures in 2020 totaled $16.1 million.

Throughout 2020, IAMGOLD completed approximately 23,000 metres of diamond and reverse circulation (“RC”) drilling. Exploration efforts continued to focus on infill and delineation drilling aimed at resource conversion, as well as continued efforts to expand existing resources and evaluate selected target areas within the exploitation permit to discover new zones of mineralization with potential to increase existing resources.

Outlook

In 2021, capital expenditures are expected to total $60 million with an early works package that includes the completion of a year-round access road, engineering for critical plant equipment, and sustainability programs targeted to promote cohesion with local communities and ensure adequate environmental protections. Additional expenditures are being incurred in the process of de-risking and positioning the project for a construction decision. Project management efforts continue with advancement of the Project in advance of an eventual construction decision.

EXPLORATION

Throughout 2020, IAMGOLD was active at brownfield and greenfield exploration projects in selected countries located in West Africa and the Americas.

In 2020, expenditures for exploration and project studies totaled $36.3 million compared to $51.2 million in the prior year, of which $27.7 million was expensed and $8.6 million was capitalized. IAMGOLD’s accounting policy is to expense exploration costs and capitalize costs of evaluating the technical feasibility and commercial viability of extracting a mineral resource, including those on or adjacent to existing mine sites. The decrease in total exploration and project expenditures reflected challenges and program deferrals associated with the global COVID-19 pandemic. Drilling activities on active projects and mine sites totaled approximately 192,000 metres for the year, within the 2020 program guidance.

OUTLOOK

In 2021, planned exploration program spending (excluding project studies) will total $56 million, comprising near mine brownfield and greenfield exploration programs. Brownfield programs will continue to focus on resource conversions at all operational sites, as well as evaluate associated regional targets to identify and delineate, as required, potential new satellite resources to sustain future production, including advancing the “hub-and-spoke” operational concept for Westwood at the Fayolle and Rouyn Gold projects in Quebec. Greenfield programs will continue to focus on the delineation and expansion of resources at IAMGOLD’s development and advanced resource stage projects including: the Gosselin zone at the Côté Gold Project in Ontario, the Diakha deposit and Karita discovery near the Boto Gold Project as part of the Bambouk regional program in West Africa, and at the Nelligan Gold Project in Quebec. In addition, IAMGOLD continues to explore for new discoveries in its industry leading portfolio of advanced to early-stage greenfield projects.

The 2021 resource development and exploration program will include between 240,000 to 280,000 metres of diamond and reverse circulation (“RC”) drilling.

BROWNFIELD EXPLORATION PROJECTS

IAMGOLD’s mine and regional exploration teams continued to conduct systematic brownfield exploration and resource development work during 2020 at the Essakane, Rosebel and Westwood operations.

Essakane, Burkina Faso

As at December 31, 2020, IAMGOLD reported total attributable proven and probable reserves at Essakane, including heap leach reserves, of 101.8 million tonnes grading 0.9 g/t Au for 3.0 million contained ounces. Total attributable measured and indicated mineral resources (inclusive of reserves) totaled 126.4 million tonnes grading 1.0 g/t Au for 3.8 million contained ounces and attributable inferred resources totaled 9.2 million tonnes grading 1.1 g/t Au for 317,000 contained ounces. At the nearby Gossey satellite deposit, located approximately 15 kilometres northwest of the Essakane operation, attributable indicated mineral resources totaled 9.4 million tonnes grading 0.9 g/t Au for 262,000 contained ounces and inferred mineral resources totaled 2.6 million tonnes grading 0.9 g/t Au for 77,000 contained ounces (see news release dated February 17, 2021).

In the first quarter 2020, IAMGOLD filed a National Instrument 43-101 Technical Report on the Carbon-In-Leach (“CIL”) and Heap Leach feasibility study which supported an investment scenario to optimize the mill and increase CIL plant capacity while postponing heap leach operations until the end of CIL operations (see news release dated February 12, 2020).

During 2020, IAMGOLD completed approximately 7,200 metres of diamond and RC drilling focused on infill and resource development at the Essakane Main Zone (“EMZ”) and the Falagountou deposit, as well as at the Tassiri satellite project, located approximately 8 kilometres southwest of the EMZ.

In 2021, approximately 7,200 metres of diamond and reverse circulation drilling is planned to continue to evaluate the resource potential at select high-priority targets within trucking distance to Essakane, including GEM, Korizena, and Tassiri.

Rosebel, Suriname

As at December 31, 2020, IAMGOLD reported total estimated attributable proven and probable mineral reserves at Rosebel, including the Saramacca deposit, of 124.0 million tonnes grading 1.9 g/t Au for 4.1 million contained ounces. Total attributable measured and indicated resources (inclusive of reserves) totaled 277.2 million tonnes grading 1.0 g/t Au for 8.6 million contained ounces and attributable inferred resources totaled 67.1 million tonnes grading 0.9 g/t Au for 1.9 million contained ounces (see news release dated February 17, 2021).

During 2020, IAMGOLD completed approximately 47,150 metres of diamond and RC drilling focused on evaluating potential resource expansions in the vicinity of existing operations. In the fourth quarter 2020, approximately 15,600 metres of infill diamond drilling were completed at the J Zone, Pay Caro, Koolhoven and Rosebel pits on the Rosebel mine concession to upgrade inferred resources to the indicated category. Drilling activities at the Saramacca pit were postponed to 2021. Regional exploration activities continued to evaluate various target areas largely focused along the Brokolonko – Saramacca trend. Approximately 6,300 metres of RC drilling were completed during the fourth quarter, for a total of 7200 metres for the year.

In 2021, approximately 61,000 metres of diamond and reverse circulation drilling is planned to improve resource confidence, target resource expansions and continue to explore high priority exploration targets on the mine lease and surrounding exploration concessions.

Westwood, Canada

As at December 31, 2020, IAMGOLD reported total estimated attributable proven and probable mineral reserves at Westwood of 3.95 million tonnes grading 4.9 g/t Au for 626,000 contained ounces. Total attributable measured and indicated resources (inclusive of reserves) totaled 7.2 million tonnes grading 7.0 g/t Au for 1.6 million contained ounces and attributable inferred resources totaled 7.0 million tonnes grading 8.0 g/t Au for 1.8 million contained ounces (see news release dated February 17, 2021).

During the fourth quarter 2020, underground excavation totaled 737 metres of lateral development for a total of 5,167 metres excavated in 2020. In addition, close to 5,000 metres of resource development diamond drilling and approximately 1,370 metres of geotechnical drilling were completed in the fourth quarter for a total of approximately 11,000m metres of surface and 49,700 metres of underground resource development and geotechnical diamond drilling in 2020. The diamond drilling program focused on infilling known mineralized zones as well as resource definition drilling in areas to be mined underground. The surface program focused on upgrading inferred resources at the Grand Duc satellite pit, located 1 kilometre west of the Westwood mill.

In 2021, approximately 39,000 metres of underground and surface diamond drilling are planned that will continue to focus on resource definition and development and include 10,000 metres on surface exploration projects.

GREENFIELD EXPLORATION PROJECTS

In addition to the near-mine and brownfield exploration programs described above, IAMGOLD conducted active exploration and drilling programs on a number of early to advanced stage greenfield exploration projects during 2020. Highlights included:

Diakha-Siribaya, Mali

As at December 31, 2020, IAMGOLD (on a 100% basis) reported total indicated mineral resources of 18.0 million tonnes grading 1.3 g/t Au for 744,000 contained ounces, and inferred resources of 23.2 million tonnes grading 1.6 g/t Au for 1.2 million contained ounces (see news release dated February 17, 2021).

During the fourth quarter 2020, IAMGOLD completed approximately 300 metres of RC drilling to initiate exploration of target areas near the Siribaya Zone 1B deposit. Throughout 2020, exploration activities focused on exploring selected high-priority geochemical and geophysical targets within a 20-kilometre radius of the Diakha deposit, as well as testing for extensions of the Diakha deposit along strike to the south. Approximately 2,300 metres of diamond and RC drilling were completed in 2020.

The 2021 exploration program will involve the completion of approximately 22,000 metres of infill drilling at the Diakha deposit to upgrade inferred ounces in support of ongoing evaluation studies of the Bambouk Regional Complex concept.

Karita, Guinea

The Karita Gold Project is wholly owned by IAMGOLD and was acquired in 2017 as a granted exploration permit that covers approximately 100 square kilometres, located in Guinea between IAMGOLD’s Boto Gold Project in Senegal to the north, and its Diakha-Siribaya Gold Project in Mali to the south.

During 2019, a first pass drilling program totalling approximately 1,800 metres of RC drilling was completed from which reported assay results confirmed a new discovery of mineralization along this portion of the Senegal-Mali Shear Zone. Assay highlights include: 29.0 metres grading 2.96 g/t Au; 21.0 metres grading 9.01 g/t Au; and 16.0 metres grading 3.17 g/t Au (see news release dated October 2, 2019).

Throughout 2020, exploration efforts focused on logistical preparations and planning for the commencement of a resource evaluation drilling program. Due to significant logistical impacts arising from the COVID-19 pandemic in 2020, the program was delayed and has been re-scheduled for 2021. The 2021 exploration program will include an approximately 20,000 metre delineation drilling program to support a future maiden resource estimate.

Pitangui, Brazil

As at December 31, 2020, IAMGOLD reported (on a 100% basis) mineral resources at the São Sebastião deposit comprised of indicated resources totaling 3.3 million tonnes grading 4.4g/t Au for 470,000 contained ounces; and additional inferred resources totaling 3.6 million tonnes grading 3.8 g/t Au for 433,000 contained ounces (see news release dated February 17, 2021).

During 2020, approximately 1,100 metres of diamond drilling were completed to evaluate regional exploration targets located within the approximately 180 square kilometre exploration licenses. For much of the year, all field-based exploration activities were suspended in response to the COVID-19 pandemic.

The 2021 exploration program will continue to evaluate targeted resource expansions and evaluate selected targets on the large property position.

Monster Lake Joint Venture, Canada

As at December 31, 2020, IAMGOLD reported (on a 100% basis) inferred mineral resources of 1.1 million tonnes grading 12.1 g/t Au for 433,300 contained ounces, assuming an underground mining scenario (see news release dated February 17, 2021).

During the fourth quarter 2020, IAMGOLD acquired TomaGold’s remaining 25% interest in the Monster Lake Project. Total consideration was C$8.5 million which included a C$500,000 cash payment and the issuance of 1,464,377 common IAMGOLD shares. IAMGOLD holds an undivided 100% interest in the Project (see TomaGold’s news releases dated September 17 and November 11, 2020).

Throughout 2020, IAMGOLD completed approximately 3,000 metres of diamond drilling focused on testing the Annie Shear Zone in an effort to extend the mineralization intersected during 2019 and reported assay results which included the following highlights: 3.8 metres grading 16.9 g/t Au, 2.82 metres grading 5.63 g/t Au, and 12.3 metres grading 2.09 g/t Au (see news release dated August 13, 2020).

The 2021 exploration program will focus on identifying and evaluating new targets on a project-scale including the completion of a regional till sampling and geological mapping program. Approximately 3,400 metres of diamond drilling is also planned to continue evaluating the resource potential of the Annie Shear Zone, located along the +4 km long structural corridor hosting the Megane 325 resource.

Nelligan Joint Venture, Canada

The Nelligan Gold Project is currently operating as a 75:25 earn-in option to joint venture with Vanstar Mining Resources Inc., with IAMGOLD holding an option to earn an additional 5% interest. The Project is located approximately 15 kilometres south of the Monster Lake Project in the Chapais – Chibougamau area in Quebec.

As at December 31, 2020, IAMGOLD reported (on a 100% basis) inferred mineral resources of 97.0 million tonnes grading 1.0 g/t Au for 3.2 million contained ounces (see news release dated February 17, 2021).

Throughout 2020, IAMGOLD completed approximately 7,600 metres of diamond drilling focused on infill and step-out drilling at the Renard Zone to evaluate resource extensions at depth and along strike. Assay results from the 2020 drilling program were reported throughout the year, with highlights including: 25.1 metres grading 1.87 g/t Au, 27.0 metres grading 2.86 g/t Au, 39.1 metres grading 2.14 g/t Au, and 34.5 metres grading 1.85 g/t Au, 17.3 metres grading 7.62 g/t Au and 42.0 metres grading 1.15 g/t Au (see news releases dated June 18, August 11, and December 2, 2020).

In 2021, the results of a metallurgical sampling and testing program are expected which will provide additional information to continue to refine process flow sheet parameters, help improve IAMGOLD’s understanding of potential gold recovery, and establish grinding and milling characteristics of the mineralization. The exploration program will continue focus on resource expansion with approximately 10,000 metres of diamond drilling planned to support the completion of an updated resource estimate expected in the second half of 2021. Exploration activities will also continue to identify and evaluate new targets outside the current resource footprint elsewhere on the property.

Rouyn Option, Canada

IAMGOLD holds a purchase option with Yorbeau Resources Inc. (“Yorbeau”) for the Rouyn Gold Project, located near the city of Rouyn-Noranda in Quebec. Under the terms of the purchase agreement, IAMGOLD can acquire a 100% interest in the Project by making scheduled cash payments totaling C$4 million and completing exploration expenditures totaling C$9 million over a four year period. By the end of the expenditure period, IAMGOLD must complete a resource estimate in accordance with National Instrument 43-101, after which IAMGOLD, at its election, can purchase a 100% interest in the Project, subject to a 2% net smelter return, by paying Yorbeau the lesser of C$15 per resource ounce or C$30 million.

During 2020, IAMGOLD completed approximately 16,400 metres of diamond drilling designed to infill and test lateral extensions of the Lac Gamble zone as well as to test select high-priority targets near the historic Astoria deposit, located approximately 1 kilometre to the east of Lac Gamble zone. Assay results from Lac Gamble reported throughout the year included: 9.8 metres grading 10.4 g/t Au, 9.8 metres grading 27.8 g/t Au (including 4.4 metres grading 58.4 g/t Au), 4.1 metres grading 10.4 g/t Au, and 7.4 metres grading 8.3 g/t Au (see news releases dated May 13 and August 20, 2020).

In 2021, a 14,000 metre diamond drilling program is planned to further delineate the Lac Gamble and Astoria zones, to support a future maiden resource estimation. The program will also initiate the evaluation of the resource potential of other selected targets including in the Cinderella and Augmitto areas.

Eastern Borosi Joint Venture, Nicaragua

During the third quarter 2020, IAMGOLD divested its 70% interest in the Eastern Borosi Project to Calibre Mining Corp. Total consideration included $4.1 million in cash and shares, and a 2.0% Net Smelter Return on future production from the property in favor of IAMGOLD (see Calibre’s news releases dated August 13 and August 20, 2020).

OTHER

Loma Larga, Ecuador

IAMGOLD, through its 35.5% (December 31, 2019 – 35.6%) equity ownership interest in INV Metals Inc. (“INV Metals”), has an indirect interest in the Loma Larga gold, silver and copper project in southern Ecuador. IAMGOLD’s ownership interest in INV Metals decreased to 35.5% in the first quarter 2020 on the issuance of additional shares by INV Metals.

During the second quarter 2020, INV Metals filed a National Instrument 43-101 Feasibility Study Technical Report in support of its previously announced updated feasibility study results. The study supports the proposed development of an underground mine with anticipated average annual production of 203,000 gold equivalent ounces over a 12-year mine life with an after-tax internal rate of return of 28.3%, after-tax payback period of 2.4 years, and an after-tax net present value of $454 million using a gold price assumption of $1,400 per ounce (see INV Metals’ news release dated March 31 and April 14, 2020).

During the third quarter 2020, INV Metals completed an Environmental Impact Study and remains focused on permitting and financing Loma Larga with the goal of commencing development in 2021. In addition, INV Metals announced that the Ecuadorian Constitutional Court upheld the rights of mining concession holders, solidifying any lawful rights that were previously potentially in jeopardy (see INV Metals’ news release dated September 21, 2020).

Subsequent to year end, IAMGOLD participated in INV Metals’ private placement of common shares and acquired an additional 4.8 million common shares of INV Metals at a price of C$0.45 per share for an aggregate amount of $1.7 million (C$2.2 million). This acquisition allowed IAMGOLD to maintain a 35.5% ownership interest in INV Metals (see INV Metals’ news release dated January 29, 2021).

The Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise except as required by applicable law.

NON-GAAP PERFORMANCE MEASURES

IAMGOLD uses certain non-GAAP financial performance measures in its news release, which are described in the following section.

NET CASH FROM OPERATING ACTIVITIES BEFORE CHANGES IN WORKING CAPITAL

IAMGOLD makes reference to a non-GAAP performance measure for net cash from operating activities before changes in working capital. Working capital can be volatile due to numerous factors, including a build-up or reduction of inventories and mine plan changes. Management believes by excluding these items, this non-GAAP measure provides investors with the ability to better evaluate the cash flow performance of IAMGOLD.

Net cash from operating activities before changes in working capital does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The following table provides a reconciliation of net cash from operating activities before changes in working capital to net cash from operating activities.

GOLD MARGIN

IAMGOLD’s News Release refers to gold margin per ounce, a non-GAAP performance measure, in order to provide investors with information about the measure used by management to monitor the performance of its gold mines. The information allows management to assess how well the gold mines are performing, relative to the plan and to prior periods, as well as assess the overall effectiveness and efficiency of gold operations.

In periods of volatile gold prices, profitability changes with altering cut-off gold grades. Such a decision to alter the cut-off gold grade will typically result in a change to total cash costs per ounce, but it is equally important to recognize gold margins also change at a similar rate. While mining lower-grade ore results in less gold being processed in any given period, over the long-run it allows IAMGOLD to optimize the production of profitable gold, thereby maximizing IAMGOLD’s total financial returns over the life of the mine to maximize the total value of the asset going forward. At the same time, the site operating teams seek to achieve the best performance in terms of cost per tonne mined, cost per tonne processed and overheads.

Gold margin per ounce does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

MINE-SITE FREE CASH FLOW

Mine-site free cash flow is a non-GAAP financial performance measure calculated as cash flow from mine-site operating activities less mine-site related property, plant and equipment expenditures. IAMGOLD believes this measure is useful to investors in assessing IAMGOLD’s ability to operate its mine sites without reliance on additional borrowing or usage of existing cash.

Mine-site free cash flow does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

AVERAGE REALIZED GOLD PRICE PER OUNCE SOLD

Average realized gold price per ounce sold is intended to enable management to understand the average realized price of gold sold in each reporting period after removing the impact of non-gold revenues and by-product credits.

Average realized gold price per ounce sold does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

The following table provides a reconciliation of average realized gold price per ounce sold to revenues as per the consolidated financial statements.

ADJUSTED NET EARNINGS (LOSS) ATTRIBUTABLE TO EQUITY HOLDERS

Adjusted net earnings (loss) attributable to equity holders of IAMGOLD and adjusted net earnings (loss) attributable to equity holders of IAMGOLD per share are non-GAAP performance measures. Management believes these measures better reflect IAMGOLD’s performance for the current period and are better indications of its expected performance in future periods. These measures are used internally by IAMGOLD to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, IAMGOLD believes these measures are useful to investors in assessing IAMGOLD’s underlying performance. These measures are intended to provide additional information, but are unlikely to be comparable to similar measures presented by other issuers. These measures do not have any standardized meaning prescribed by IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Adjusted net earnings (loss) attributable to equity holders of IAMGOLD represents net earnings (loss) attributable to equity holders excluding certain impacts, net of taxes, such as changes in estimates of asset retirement obligations at closed sites, unrealized (gain) loss on non-hedge derivatives and warrants, impairment charges and reversal of impairment charges, write-down of assets, and foreign exchange (gain) loss. These measures are not necessarily indicative of net earnings (loss) or cash flows as determined under IFRS.

The following table provides a reconciliation of earnings (loss) before income taxes and non-controlling interests as per the Consolidated statements of earnings (loss), to adjusted net earnings (loss) attributable to equity holders of IAMGOLD.

1 COVID-19 expenses pertain to incremental costs incurred resulting from the impact of COVID-19 on the operations of IAMGOLD. Specifically, costs related to incremental labour, transportation, safety and other new operational measures and processes implemented to manage the impact of COVID-19. The COVID-19 expenses for the fourth quarter and year ended 2020 of $4.2 million and $22.0 million, respectively, are presented net of total subsidy received by IAMGOLD of $nil and $5.4 million, respectively,
2 Care and maintenance costs at Westwood does not include subsidy received by IAMGOLD of $1.2 million, which is included in COVID-19 expenses, net of subsidy.

After adjusting reported net earnings for those items not considered representative of IAMGOLD’s core business or indicative of future operations, IAMGOLD had adjusted net earnings from continuing operations in the fourth quarter and year ended 2020 of $19.1 million and $87.7 million, respectively.

TOTAL CASH COSTS PER OUNCE PRODUCED

IAMGOLD’s News Release and refers to total cash costs per ounce produced, a non-GAAP performance measure, in order to provide investors with information about a key measure used by management to monitor performance. This information is used to assess how well the producing gold mines are performing compared to plan and prior periods, and also to assess their overall effectiveness and efficiency.

Total cash costs are calculated in accordance with a standard developed by the Gold Institute, which was a worldwide association of gold and gold product suppliers, including leading North American gold producers. Although the Gold Institute ceased operations in 2002, the standard is still an accepted measure of reporting cash costs of gold production in North America. Adoption of the standard is voluntary and the cost measures presented herein may not be comparable to other similarly titled measures of other companies. Costs include mine site operating costs such as mining, processing, administration, royalties, production taxes, and realized derivative gains or losses, exclusive of depreciation, reclamation, capital expenditures and exploration and evaluation costs. These costs are then divided by IAMGOLD’s attributable ounces of gold produced by mine sites in commercial production to arrive at the total cash costs per ounce produced.

IAMGOLD reports the measure for the Essakane, Rosebel and Westwood mines.

The measure, along with revenues, is considered to be one of the key indicators of a company’s ability to generate operating earnings and cash flow from its mining operations. Total cash costs does not have any standardized meaning prescribed by IFRS, are unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures are not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.

The following table provides a reconciliation of total cash costs per ounce produced for gold mines to cost of sales, excluding depreciation expense as per the consolidated financial statements.

ALL-IN SUSTAINING COSTS PER OUNCE SOLD

IAMGOLD believes, although relevant, the current total cash costs measure commonly used in the gold industry does not capture the sustaining expenditures incurred in producing gold, therefore, may not present a complete picture of a company’s operating performance or its ability to generate free cash flow from its current operations. For these reasons, members of the World Gold Council (“WGC”) defined an all-in sustaining costs measure which better represents the costs associated with producing gold. The WGC is a non-profit association of the world’s leading gold mining companies, established in 1987 to promote the use of gold.

The all-in sustaining costs (“AISC”) per ounce sold measure better meets the needs of analysts, investors and other stakeholders of IAMGOLD in assessing its operating performance and its ability to generate free cash flow. The definition of AISC, on an attributable basis, commences with cost of sales, excluding depreciation expense, and includes sustaining capital expenditures, sustaining exploration and evaluation expenses, sustaining lease principal payments, environmental rehabilitation accretion and depreciation, by-product credits, and corporate general and administrative costs. Classified as sustaining capital are expenditures which are required to maintain existing operations, including sustaining capitalized stripping, underground mine development costs relating to producing areas, ongoing replacement of mine equipment and capital spares, tailings and other facilities, capitalized brownfield exploration costs and other capital expenditures.

This measure seeks to represent the cost of selling gold from current operations, and therefore does not include capital expenditures attributable to development projects or mine expansions, greenfield exploration expenses, income tax payments, working capital defined as current assets less current liabilities (except for inventory adjustments), items needed to normalize earnings, interest costs or dividend payments.

Consequently, this measure is not representative of all of IAMGOLD’s cash expenditures and is not indicative of IAMGOLD’s overall profitability. The calculation of AISC per ounce sold is based on IAMGOLD’s attributable interest in sales from its gold mines. The usage of an attributable interest presentation is a fairer and more accurate way to measure economic performance than using a consolidated basis. IAMGOLD reports the AISC per ounce sold measure on an attributable sales basis, compared with IAMGOLD’s current total cash costs presentation, which is on an attributable production basis.

IAMGOLD reports the measure with and without a deduction for by-product credits and reports the measure for the Essakane, Rosebel and Westwood mines.

AISC does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. This measure is not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.
