Financial Results

Net earnings (loss) per share attributable to equity holders was $(0.41) for the fourth quarter and $(0.53) for the year ended

December 31, 2021. Adjusted net earnings (loss) per share attributable to equity holders 1 was $0.09 for the fourth quarter

and $0.06 for the year ended December 31, 2021, after adjusting for the non-cash net realizable value (“NRV”) write-down

of ore stockpiles and impairment charge on Rosebel, discussed below.

Loss before interest, income taxes, depreciation an d amortization1 was $193.4 million for the fourth quarter and earnings

before interest, income taxes, depreciation and amortization (“EBITDA”)1 was $27.1 million for the year ended December

31, 2021. Adjusted EBITDA 1 was $90.0 million for the fourth quarte r and $355.7 million for the year ended December 31,

2021.

Mine-site free cash flow1 was $12.3 million for the fourth quarter and $133.8 million for the year ended December 31, 2021.

Annual mine-site free cash flow was down $89.4 million from the prior yea r, primarily due to lower operating cash flow at

Rosebel ($111.6 million) and Westwood ($68.5 million), and higher capital expenditures at Rosebel ($ 30.8 million) and

Essakane ($21.9 million), partially offset by higher operating cash flow at Essakane ($136.5 million).

Net cash from operating activities was $67.5 million ($76.0 million before changes in working capital) for the fourth quarter

and $285.0 million ($293.0 million before changes in working capital) for the year ended December 31, 2021. Annual n et

cash from operating activities was down $62.6 million from the year prior, primarily due to lower revenue and higher cash

operating costs ($98.2 million), higher income tax es paid ($10.5 million), partially offset by higher cash receipts from the

settlement of derivatives ($31.7 million) and proceeds from insurance claims ($10.2 million).

The updated mineral reserves and mineral resources estimates and life -of-mine plan for Rosebel were considered by the

Company to be an indicator of impairment. A non-cash impairment charge of $205.1 million (post-tax impairment charge of

$132.9 million) was recognized in the consolidated statements of earnings (loss) in the fourth quarter.

Attributable gold production was 153,000 ounces for the fourth quarter and 601,000 ounces for 2021, near the top of the

updated production guidance.

Cost of sales (excluding depreciation) per ounce sold was $1,597 for the fou rth quarter and $1,270 per ounce sold for the

year ended December 31, 2021, up 20% from $1,057 per ounce sold in 2020. Included was a non-cash NRV write-down of

ore stockpile and finished goods inventories of $147 per ounce sold (2020 - $nil) comprised of $49 per ounce included in

cash costs and AISC per ounce sold as short -term and $98 per ounce excluded from cash cost and AISC per ounce sold

as long-term, and the positive impact of realized derivative gains of $19 per ounce sold (2020 – loss of $27 per ounce sold).

Excluding the NRV write-down, cost of sales per ounce sold was higher primarily due to lower production and sales volumes.

Cash cost1 per ounce sold was $1,184 for the fourth quarter and $1,132 per ounce sold for the year ended December 31,

2021, in line with the updated guidance. Cash costs were up 15%, from $988 per ounce sold in 2020, due to higher operating

costs, which included a non -cash NRV write-down of short -term ore stockpile and finished goods inventories of $50 per

ounce sold (2020 - $nil), and lower production and sales volumes.

AISC per ounce sold was $1,537 for the fourth quarter and $1,426 per ounce sold for the year ended December 31, 2021,

near the top end of the updated guidance. AISC were up 16%, from $1,232 per ounce sold in 2020, primarily due to lower

production and sales volumes as well as higher sustaining capital expenditures. Included was a non-cash NRV write-down

of short-term ore stockpile and finished goods inventories of $50 per ounce sold (2020 - $nil).

The DARTFR2 (days away, restricted, transferred duty frequency rate) was 0.3 7 and the TRIFR2 (total recordable injuries

frequency rate) was 0. 76 for 2021, below the global annual targets of DARTFR 0.51 and TRIFR 0.85, respectively. Côté

Gold has surpassed over 3.4 million hours with no lost time injuries to date.

Exploration

Exploration projects – greenfield $ 5.6 $ 7.4 $ 27.8 $ 19.9

Exploration projects – brownfield1 5.5 4.8 19.6 16.4

$ 11.1 $ 12.2 $ 47.4 $ 36.3

1. Exploration projects - brownfield for the fourth quarter 2021 included near -mine exploration and resource development of $3.0 million (third quarter 2021 - $2.5

million, fourth quarter 2020 - $2.7 million, 2021 - $10.7 million, 2020 - $8.4 million).

For the fourth quarter, expenditures for exploration and project studies totaled $11.1 million, of which $8.1 million was

expensed and $3.0 million was capitalized. During the year, drilling activities on active projects and mine sites totaled

approximately 195,000 metres.

Liquidity and Capital Resources

As at December 31, 2021, the Company had $544.9 million in cash and cash equivalents, $7.6 million in short -term

investments and net cash 1 of $1 6.3 million. Approximately $498 million was available under the Company ’s secured

revolving credit facility (the "Credit Facility") resulting in available liquidity1 at December 31, 2021 of $1.1 billion.

During 2021, the Company entered into gold sale prepayment arrangements (the "2022 Prepay Arrangements") at a

weighted average cost of 4.45% per annum in respect of 150,000 gold ounces. These arrangements have an average

forward contract price of $1,753 per ounce on 50,000 gold ounces and a collar range of $1,700 to $2,100 per ounce on

100,000 gold ounces. This will result in a total prepayment to the Company of $236 million over the course of 2022 and the

requirement on the part of the Company to physically deliver 150,000 gold ounces over the course of 2024. The 2022

Prepay Arrangements have the effect of rolling the 150,000 ounce gold sale prepay arrangement entered into in 2019 (the

“2019 Prepay Arrangement”), from 2022 to 2024 after the completion of the construction of Côté Gold. In January 2022, the

first 12,500 ounces were delivered into the 2019 Prepay Arran gement and the Company received $2.5 million in cash in

relation to the collar on the 2019 Prepay Arrangement and $19.7 million in cash pursuant to the 2022 Prepay Arrangements.

The Company is in the process of finalizing lease agreements for mobile equip ment with a value of approximately $125

million that will be purchased on behalf of the unincorporated Côté Gold joint venture. Sumitomo Metal Mining Co. (“SMM”)

will guarantee some of the leases for their 30% ownership. The remaining Côté Gold project dev elopment costs are net of

these leases, as previously disclosed.

In addition to the gold sale prepayment arrangements noted above, and in order to mitigate volatility during the construction

of Côté Gold between 2021 and mid-2023, the Company entered into certain derivative contracts in respect of certain of its

future gold sales, exchange rates and certain other commodities exposure. At December 31, 2021, approximately 26% and

10% of the Company ’s 2022 and 2023 estimated attributable production, respective ly, was hedged at average prices

between $1,300 per ounce and $3,000 per ounce. The Company has also entered into various oil and currency hedging

transactions. Refer to the MD&A "Market Risk – Summary of Hedge Portfolio" for information relating to the Co mpany’s

outstanding derivative contracts.

The net cash generated by operations is highly dependent on the gold price as well as other factors, including the USDCAD

exchange rate. The Company is scheduled to complete the remaining construction of Côté Gold during 2022 and 2023

resulting in significant capital expenditures that, together with sustaining and expansion capital expenditures at its existi ng

mines, are expected to exceed total current cash and cash generated from operations. As a result, the Compa ny expects

to make its first draw down on its credit facility in the first half of 2022 and expects to draw down most this facility over the

course of 2022 and 2023. Assuming the continuation of prevailing commodity prices and exchange rates, operations

performing in accordance with the 2022 guidance and 2023 plan, and no significant change in the Côté Gold costs or the

time of achieving commercial production (see also “Côté Gold Project” section below), the Company believes it should have

adequate liquidity, in addition to its existing credit facility and the additional equipment leases, to implement its near -term

operational plans and complete the development of Côté Gold.

To ensure adequate liquidity and flexibility, the Company regularly reviews expenditures and assesses opportunities taking

into consideration current liquidity, the capital markets, foreign exchange rates, ongoing operational and financial

performance and progress in the development of projects. As a result, the Company may take additiona l measures to

increase its liquidity and capital resources including additional financing, strategically disposing of assets or pursuing jo int-

venture partnerships.

of $42.9 million (third quarter 2021 - $nil; 2020 - $nil and 2019 - $nil), in addition to sustaining l ease principal payments, environmental rehabilitation accretion and

depletion, and prior period operating costs, partially offset by by -product credits.

8 Includes expansion capitalized stripping for the fourth quarter 2021 of $21.1 million (third quarter 2021 - $21.8 million) and 2021 of $65.0 million (2020 - $57.8 million

and 2019 - $30.4 million).

9 Cost of sales, cash costs and AISC per ounce sold may not be calculated based on amounts presented in this table due to round ing.

Essakane continued to deliver strong results and achieved attributable gold production of 98,000 ounces in the fourth quarter

and a record 412,000 ounces for the year. Production was lower in the quarter due to lower grades in the mining schedule,

partially offset by higher recovery.

Mining activity of 15.0 million tonnes for the fourth quarter was in line with the prior quarter, while the strip ratio of 2.7 was

lower by 7%. The mine began sequencing out of the enriched ore zones at the bottom of the main pit resulting in lower

grade in the fourth quarter. Mining activity of 60.4 million tonnes for the year was higher than in 2020 as a result of operational

efficiencies and reduction of cycle times achieved from the modifications to the hauling fleet. The strip ratio of 2.8 in 202 1

Page | 6 of 27

was higher by 12% as a result of continued focus on stripping campaigns in the upper benches during the year.

Mill throughput of 3.3 million tonnes in the fourth quarter was in line with the prior quarter and plant availability remaine d

above 92%. Mill throughput of 12.9 million tonnes in 2021 was 4% higher than in 2020 as a result of the mill debottlenecking

project and other optimization initiatives.

As the COVID-19 situation evolved towards the end of 2021 and into 2022, measures and controls are being strengthened

to limit transmission, reinforce awareness and promote vaccination. Approximately 64% of the workforce is fully vaccinated.

The IAMALLIN improvement project has now progressed to the execution phase and is focusing on mill and mine

productivities and working capital including spare parts management, operations efficiency and maintenance programs.

The Company reported on certain security incidents and developments in Burkina Faso ( see news releases dated

September 1, 2021, October 29, 2021, November 1, 2021 and January 25, 2022). All IAMGOLD personnel continues to be

safe and associated supply chains have not been significantly impacted by the security situation. The workforce has been

progressively increased to close to normal levels following a tempo rary reduction towards the end of 2021 , while the

Company continues to monitor the situation . The Company continues to expect that 2022 production will be within the

guidance range. The Company has taken proactive measures to ensure the safety and security of in-country personnel and

continuously evaluates the security environment. Investments in infrastructure in the region and at the mine site are being

made to further strengthen security measures, while regularly engaging with relevant authorities and ot her partners in

Burkina Faso in relation to security in the region as well as its supplies and transportation routes.

Outlook

Attributable gold production at Essakane in 2022 is expected to be in the range of 360,000 to 385,000 ounces, with

production expected to be relatively steady over the year as planned grades normalize closer to reserve grades, offset

slightly by higher recoveries due to expected lower graphitic content. Looking beyond 2022, Essakane is expected to

continue to produce in the range of 325,000 to 375,000 ounces in each of 2023 and 2024. Cash costs are expected to

increase slightly due to inflationary cost pressures, changes in transportation and logistics in relation to our workforce, and

the upgrade to transportation infrastructure at and outside of the mine site to address the security situation. The cost of our

main consumables consisting of explosives, cyanide, lime and grinding media are expected to be 5% to 7% higher on

average compared to 2021 pricing, resulting in an approximate 1% to 2% increase in cash costs reflected in 2022 guidance

estimates. The increase in AISC reflects the increase in operating costs, as well as higher sustaining capital and capitalized

stripping. Capital expenditures are expected to be approximately $170 million, compared to $136 million in 2021, primarily

consisting of capitalized stripping.

Rosebel achieved attributable gold production of 42,000 ounces in the fourth quarter and 154,000 ounces for the year.

Production increased in the quarter due to higher grades processed and higher recovery.

Material mined of 13.8 million tonnes in the quarter reflected the continued ramp up of mining activities over the year. Focus

on strategic pushbacks and stripping continued. The backlog in maintenance work on the aging mining fleet and the resulting

lower equipment availability and reliability continued to be challenges during the quarter, however, deliveries of new mobile

equipment replacing the aged mining fleet have commenced.

Mill throughput of 2.4 million tonnes in the fourth quarter decreased 8% compared with the prior quarter due to maintenance

related work. Increased recoveries in addition to the higher sales and drawdown of inventories were due to the efficiency

improvements of the carbon adsorption/desorption circuit which were completed near the en d of the quarter. The increase

in recoveries and lower in-circuit gold inventory levels are expected to be maintained from 2022 onward. Rosebel provided

48% of the mill feed at an average grade of 0.72 g/t and Saramacca provided 37% of the mill feed at an average grade of

0.95 g/t. The remaining 15% mill feed was from low grade long-term ore stockpiles at an average grade of 0.58 g/t.

The COVID-19 situation at site and in Suriname has started to stabilize and improved during the fourth quarter, however

the new Omicron variant remains a concern as new cases in January 2022 were the highest recorded since the start of the

pandemic. Throughout 2021, workforce productivity levels were adversely impacted as a result of approximately 40% of the

total workforce having had COVID-19 since the start of the pandemic. The site continues to monitor and implement mitigating

measures to reduce the impact, including actively engaging in community related initiatives. Approximately 41% of the

workforce was fully vaccinated as of December 2021.

The Company has been collaborating with the government task force assigned to manage the security situation at site with

regards to illegal miners. The government security force have increased their patrols of the mine site during the fo urth

quarter, resulting in some decreases in pit intrusions.

The construction of required infrastructure at the Saramacca project, including the facility pad, the sedimentation dams

(functional), haul road, and public road crossings, as well as the majori ty of the previously planned activities related to the

West Dump rock drains have been completed by the end of the fourth quarter. Additionally, the dewatering wells, further

development of the rock drains and the completion of other earthworks activities, including slope remediation and bypass

road phase 2, are expected to be completed during 2022.

The Company has completed an updated Mineral Resource and Mineral Reserve estimate as of December 31, 2021 and

an updated life -of-mine plan for Rosebel ( see new s release dated January 12, 2022 ). The updated Mineral Reserves

estimate for Rosebel (on 100% basis and at $1,300 gold price) is comprised of Proven and Probable Mineral Reserves

totaling 3.8 million ounces of gold and the updated Mineral Resources estimate (on a 100% basis, at $1,500 gold price and

including Mineral Reserves) is comprised of Measured and Indicated Mineral Resources totaling 6.3 million ounces of gold.

Production is expected to ramp up to an estimated 300,000 ounces per year on a 100% basis starting in 2025 until the

current expected end of mine life in 2033 based on the updated Mineral Reserves estimate.

The updated mineral reserves and mineral resources estimates and life -of-mine plan for Rosebel were considered by the

Company to be an indicator of impairment for the Rosebel cash generating unit, which consists of the Rosebel complex and

the Rosebel royalty payable to Euro Resources S.A. by the Company. As a result, an assessment was performed and it

was determined that the carrying amount exceeded its recoverable amount of approximately $373.8 million. This resulted

in a non -cash impairment charge of $205.1 million (post -tax impairment charge of $132.9 million) being recorded in the

consolidated statements of earnings (loss) in the fourth quarter.

The IAMALLIN improvement project is in the discovery phase with on-site consultation commencing in the first half of 2022.

Outlook

Attributable gold production at Rosebel in 2022 is expected to be in the range of 155,000 to 180,000 ounces, with production

expected to be stronger in the second half after the seasonal rains subside. In addition, recoveries are expected to increase

compared to 2021 from continuing refurbishment initiatives at the mill complex. Cash costs are expected to increase due to

inflationary cost pressures, however unit costs per ounce sold are expected to decrease with higher expected production

levels. The cost of our main consumables consisting of explosives, cyanide, lime and grinding media are expected to be

5% to 7% higher compared to 2021 pricing, resulting in an approximate 1% to 2% increase in cash costs reflected in 2022

guidance estimates. Capital expenditures are expected to be approximately $140 million, compared to $99 million in 2021,

the majority of which relate to capitalized stripping and Saramacca development. Looking beyond 2022, Rosebel is expected

to produce 180,000 to 200,000 of attributable gold ounces in 2023 and 2024. As a result of the Company's current capital

allocation prioritization, the Company will be commencing a strategic review process to evaluate options for Rosebel.
