Insights

IAMGOLD's 2024 performance marks a transformative year in its evolution to a mid-tier gold producer, with several notable achievements that strengthen its market position. The 43% increase in production to 667,000 ounces demonstrates successful execution of growth strategies, particularly the rapid ramp-up of Côté Gold, which achieved commercial production faster than typical for large-scale Canadian gold mines.

The financial results are particularly impressive, with $1.63 billion in revenue and $486 million in operating cash flow. Cost management has been exemplary, with AISC of $1,716 per ounce trending toward the lower end of guidance, despite industry-wide inflationary pressures. This cost discipline, combined with higher gold prices, has significantly enhanced operating margins.

The Westwood turnaround deserves special attention - generating $94.4 million in mine-site free cash flow and warranting a $455.5 million impairment reversal, validating management's rehabilitation strategy. This success story demonstrates IAMGOLD's operational expertise in underground mining.

Looking ahead to 2025, the production guidance of 735,000-820,000 ounces reflects continued growth momentum. The successful mineral reserves replacement at Essakane and significant resource increases at Nelligan (up 56% in Indicated resources) provide strong organic growth potential. The expanded $650 million credit facility and dual credit rating upgrades reflect strengthening financial fundamentals and improved market confidence.

The strategic increase in Côté ownership to 70% positions IAMGOLD to capture greater value from this cornerstone asset, which has demonstrated capability to operate above nameplate capacity. With combined measured and indicated resources of 16.5 million ounces between Côté and Gosselin, there's substantial potential for Côté to become one of Canada's largest gold mines.

Toronto, Ontario--(Newsfile Corp. - February 20, 2025) - IAMGOLD Corporation (NYSE: IAG) (TSX:IMG) ("IAMGOLD" or the "Company") today reported its financial and operating results for the fourth quarter and year ended December 31, 2024. Preliminary operating results for the fourth quarter and year ended 2024, alongside operating guidance estimates for 2025, were previously disclosed on January 14, 2025.

"Last year was a monumental year for IAMGOLD, as the Company achieved key milestones to position the Company as a dynamic, modern multi-asset mid-tier gold producer that is poised for potential free cash flow expansion while retaining significant growth opportunities," said Renaud Adams, President and Chief Executive Officer of IAMGOLD. "IAMGOLD finished 2024 with total attributable gold production of 667,000 gold ounces, a 43% increase from the prior year and in line with our previously raised guidance estimates. This strong performance was driven by the start of production at Côté Gold and the outperformance of Essakane and Westwood. "

"The Côté Gold team had a very strong year, as the mine achieved among the quickest ramp-ups to commercial production for a large-scale open pit gold mine in Canada. Our efforts continue to be focused on the ramp up of the processing plant towards achieving the nameplate throughput rate of 36,000 tpd at a steady, sustainable rate. We are prioritizing stability and operating consistency, while refining and balancing our maintenance schedules for wear and tear. The plant has demonstrated its ability to operate above nameplate over multi-day periods, and with an additional secondary crusher scheduled to be installed in November, we look forward to determining the potential of the plant to sustainably achieve over nameplate with minimal capital spending in the near term. Longer term, we will continue to pursue improvements in mining and processing activities and investigate the potential options to bring into the mine plan the full resource base estimate of the Côté and Gosselin zones - which combine for over 16.5 million ounces of measured and indicated and 4.2 million ounces of inferred resources - to define Côté Gold among Canada's largest gold mines in operation."

"At Essakane, the mine achieved the top end of guidance with strong, stable operations through the year. While the cost of operations in country have risen over the last two years, Essakane is positioned to generate strong cash flows as waste stripping is scheduled to decline year over year. The exploration team has done an amazing job with the updated Mineral Reserves estimate announced today in which we saw Essakane more than replace reserve depletion, thereby implying the potential for further mine life extension within the secured perimeter of our operations."

"Finally, the transformation of Westwood has been among the top mining success stories in 2024, as the last few years of redevelopment and rehabilitation resulted in the successful turnaround of the mine where it finished the year generating $94.4 million in mine site free cash flow. Further, this achievement was during a transitional year as our teams completed the safe rehabilitation of the mine and began standard underground development and mining operations."

OUTLOOK

Production

	Actual 2024	Full Year Guidance 2025
Côté Gold (000s oz)	124	250 - 280
Westwood (000s oz)	134	125 - 140
Essakane (000s oz)	409	360 - 400
Total attributable production¹ (000s oz)	667	735 - 820

Attributable ounces account for IAMGOLD ownership interests of: Côté Gold - weighted average to account for the repurchase of the 9.7% interest effective November 30, 2024, returning IAMGOLD's interest to 70%; Westwood - 100%; Essakane - 90%.

Total attributable production for IAMGOLD in 2025 is expected to be in the range of 735,000 to 820,000 ounces, an increase from 2024 production, driven by the ramp-up of Côté Gold to nameplate production later during 2025 and continued strong production levels from Essakane and Westwood. Production at Côté Gold in its first full year, on a 100% basis, is expected to be between 360,000 to 400,000 ounces for the year (250,000 to 280,000 ounces on an attributable basis). For further details, refer to the operations section of each mine below.

Consists of Westwood and Essakane on an attributable basis of 100% and 90%, respectively. For Côté Gold, the attributable basis in 2024 is based on IAMGOLD's ownership of 60.3% up to November 2024, thereafter, increasing to 70% for December 2024. 2024 all-in sustaining cost for Côté Gold represents the five-month period following achievement of commercial production. For 2025, the attributable basis for Côté Gold is 70% for all periods.
This is a non-GAAP financial measure. See "Non-GAAP Financial Measures".

Cash costs on a consolidated basis are expected to be in the range of $1,200 to $1,350 per ounce sold, a slight increase from last year primarily as a result of an increase in expected cash costs at Essakane. AISC for IAMGOLD are expected to be in the range of $1,625 and $1,800 per ounce sold, in line with last year as a result of the ramp up of Côté Gold and reduced capitalized waste stripping at Essakane.

The full year guidance is based on the following 2025 full year assumptions, before the impact of hedging: average realized gold price of $2,500 per ounce, USDCAD exchange rate of 1.35, EURUSD exchange rate of 1.11, average Brent oil price of $75 per barrel and WTI price of $70 per barrel.

Capital expenditures guidance (±5%).
Includes $11 million of capitalized exploration and evaluation expenditures also included in the Exploration Outlook guidance table.

Capital expenditures for IAMGOLD in 2025 are expected to total $310 million, of which $290 million is categorized as sustaining capital. Capital expenditures are down from the prior year, as a result of the completion of expansion capital outlays as Côté Gold construction and commissioning was completed earlier in the year. Sustaining capital estimates are expected to decline going forward, as Côté completes the construction of the full tailings dam footprint and as capitalized waste stripping declines at Essakane based on the current mine plan.

Exploration Outlook

Exploration expenditures for 2025 are expected to be approximately $38 million, the majority of which will be expensed. The largest exploration spend will be at Côté Gold of approximately $13 million attributable to IAMGOLD including the Gosselin resource delineation drilling program, Essakane at approximately $7 million, followed by Nelligan/Monster Lake at approximately $6 million.

Income Taxes Paid and Depreciation Outlook

The Company expects to pay cash taxes in the range of $120 to $130 million during 2025. Cash tax payments do not occur evenly by quarter, as amounts paid in a quarter can include payments of the final balance of the prior year taxes and payments of instalments for the current year, both required to be made at times as prescribed by different countries. There are no significant cash taxes expected in respect of the new global minimum top-up taxes ("GloBE"). The income taxes paid guidance does not include cash tax obligations arising as part of the Bambouk sales process. See "Bambouk Assets" for additional details.

Depreciation expense for 2025 is expected to be $450 million (±5%) with increased depreciation expense due to the increase in the value of depreciable property, plant and equipment following the completion of construction and commencement of commercial operations at Côté Gold and the impairment reversal at the Westwood cash generating unit ("CGU").

ENVIRONMENTAL, SOCIAL AND GOVERNANCE

The Company is committed to maintaining its culture of accountable mining through high standards of Environmental, Social and Governance practices, including its commitment to strive for the goal of Zero Harm®, in every aspect of its business.

Health and Safety

Health and safety is core to the Company's pursuit of its Zero Harm® vision. Through various prevention programs, the Company continually promotes a wellness program and a safe work environment at its sites. The TRIFR (total recordable injuries frequency rate) was 0.63 as at December 31, 2024 (compared to 0.69 as at December 31, 2023), tracking below the Company's target of 0.66.

In the fourth quarter of 2024, teams from each operation participated in workshops to review and identify the Company's health and safety leading and lagging indicators for 2025 with a continued focus on Critical Risk Management and Visible Felt Leadership.

Environmental

In 2024, the key environmental focus areas for the Company were water and biodiversity. In the fourth quarter 2024, the Company reached the final stages of the development of a water stewardship framework that takes a catchment-based planning approach, to enhance its management capacities in this area and allow the Company to evaluate its impacts and contributions to regional watersheds. Part of this water stewardship framework included the development of a Water Management Standard and updating of the Water Policy. In 2024, the Company also expanded on the initial biodiversity assessment performed in 2022 to develop a more comprehensive roadmap to understand its dependencies and impacts on nature and evaluate the appropriateness of the Company reporting against the Taskforce on Nature-related Financial Disclosures. The Company also initiated decarbonization and energy management assessments of its sites, in support of the Company's decarbonization aspirations.

At Essakane, the Falagountou Closure Plan was filed at the end of May 2024. The Closure Plan for the Essakane pit that was submitted in 2019 is currently being updated and the target timeline for the submission is the first quarter 2025. Essakane conducted a management review of its environmental management system. The site continued to run an environmental 'stop incident' campaign to educate and empower employees to recognize and respond to environmental risks. External audits were also performed on Tailings, Water and Health & Safety management systems at Essakane, in support of, but separate from the TSM audit.

At Westwood, external audits were performed on Tailings, Water and Health & Safety management systems. The 2021 Westwood Closure Plan was approved on June 11, 2024, and the Doyon Closure Plan was approved on July 3, 2024, by the Quebec Ministry of Natural Resources and Forestry. Westwood continues to pilot water recycling projects to reduce water withdrawal from the Bousquet River.

Côté Gold submitted its Phase 1 Environmental Effects Monitoring Report to Environment and Climate Change Canada. Côté Gold submitted its greenhouse gas emissions report for 2023 to Ontario's Emissions Performance Standard Program, which required reasonable assurance under ISO 14064 in September 2024.

As of December 31, 2024, there were zero environmental significant incidents.

Social Performance

In 2024, the Company reviewed its approach to community investment and initiated the development of a Community Investment Strategy. In the fourth quarter 2024, the Company began the implementation of a new Community Investment Standard that provides guidance on investments that aligns with the Company's community investment focus areas. Each operation continues to engage with their communities of interest and support community investment initiatives. At Essakane, key engagements and activities included discussions on economic, social, security, and resettlement topics, engagements with stakeholders as part of the Essakane Closure Plan and monitoring of artisanal miners. The Company continues to address legacy issues from the original Relocation Action Plan ("RAP 1") with the rebuilding of select houses. The Company is expected to complete all rebuilding efforts associated with RAP 1 within a three-year time period.

During the fourth quarter 2024, IAMGOLD entered into a partnership agreement with Project CURE to deliver two 40-foot cargo containers of medical supplies to seven health centres in the Dori and Gorom-Gorom medical districts in 2025.

Throughout the fourth quarter 2024, Côté Gold hosted: Mattagami First Nation, academic institutions and the Federal Economic Development Agency for Northern Ontario ("FedNor") for tours of the site to share information about the mine and IAMGOLD's approach to responsible mining. IAMGOLD and Côté Gold representatives participated in the Organization for Economic Co-operation and Development ("OECD") Mining Regions and Cities Conference in Sudbury.

At Westwood, the team continued to meet with Abitibiwinni First Nation related to the development of an Impact Benefit Agreement.

Indigenous Relations

As a Canadian business committed to responding to the Truth and Reconciliation Commission of Canada's Calls to Action, the Company continues to take meaningful action towards reconciliation by respecting and upholding Indigenous rights, founded upon relationships that foster trust, transparency and mutual respect. In support of this commitment, during the fourth quarter we hosted an educational workshop in our Toronto office focused on the historical and current context of Indigenous relations in Canada.

Operations

Attributable gold production was 124,000 ounces (199,000 ounces on a 100% basis) in the first nine months of operations as the plant poured first gold on March 31, 2024, achieved commercial production on August 1, 2024, and completed a comprehensive mill shutdown in September to deploy key improvements to stabilize the crushing circuit and attend to areas of high wear in the plant. Attributable production in the fourth quarter 2024 was 62,000 ounces (96,000 ounces on a 100% basis), higher by 21,000 than the third quarter 2024. In November and December, Côté produced 37,000 ounces (100% basis) each month.

Mining activity totaled 10.8 million tonnes in the fourth quarter 2024, an increase over the prior quarter and ore tonnes mined increased to 3.6 million tonnes during the period with an associated decrease in the strip ratio to 2.0:1 waste to ore. During the fourth quarter, three additional CAT 793 autonomous haul trucks were commissioned, for a total of 21 in the haulage fleet. During December, mining activities demonstrated the ability to mine at sustainable rates of 150,000 tpd over a weekly period. The average grade of mined ore was 1.07 g/t in the fourth quarter 2024, in line with the mine plan. The reconciliation between the grade control and reserve models continues in line with expected tolerances.

Mill throughput in the fourth quarter 2024 totaled 2.4 million tonnes, approximately 49% higher than the throughput of the prior quarter. Head grades of 1.34 g/t were in line with the mine plan, which requires feed material from a combination of higher grade direct-feed ore and higher-grade stockpiles. Recoveries in the plant averaged 91% in the quarter.

The target is to achieve the steady-state nameplate throughput rate of 36,000 tpd in the fourth quarter of 2025. In December, the plant operated at an average of 87% of the designed throughput level over a two-week period, prior to an unscheduled shutdown due to a split in a conveyor belt associated with ramp-up wear and tear. Repairs were made to the belts and replacement with a modified design was completed in January 2025. When online in December, the plant averaged 1,593 tph, or effectively 106% of nameplate, with a record daily throughput of 42,635 tonnes per day.

Subsequent to quarter end, the HPGR rollers demonstrated accelerated wear necessitating a changeover ahead of schedule and limiting the secondary crushing capacity in January. The changeover of the HPGR rolls was completed in February 2025 with operating and maintenance procedures adjusted to maximize lifespan and optimize future changeover windows. Inside the plant, the grinding circuit was also impacted early in the quarter, due to repairs required on one of the Vertimills following a faulty start-up post-maintenance. Prevention and mitigation procedures have been put in place. Plant throughput is expected to be lower in the first quarter as a result of the impact of the timing of these maintenance issues, while operating guidance has been maintained (as discussed below).

Financial Performance (attributable basis)

For accounting purposes, revenue and cost of sales were recognized at 60.3% from the commencement of the first sale in April 2024 up to the repurchase of the 9.7% Transferred Interest from Sumitomo on November 30, 2024. Revenue and cost of sales were recognized in accordance with IAMGOLD's increased ownership level of 70% during December.

Production costs of $52.8 million were incurred during the three months ended December 31, 2024, and $107.2 million incurred for the full year. Production cost for the full year is net of $33.9 million of operating expenditures incurred in the period preceding the achievement of commercial production on August 1, which relates to milling and surface operating costs that have been capitalized during commissioning and ramp-up efforts in advance of achieving commercial production.

Mining cost was $4.19 and $3.90 per tonne mined during the three and twelve months ended December 31, 2024, respectively. Costs are higher than planned due to higher than planned rehandling of ore to achieve the required segregation of high grade material, higher maintenance costs on the drill rigs to improve availability and higher one-time contractor costs to support the ramp-up of the mine.
Mill cost was $17.59 and $17.32 per tonne milled during the three and nine months ended December 31, 2024, respectively. Unit costs remain high as the average throughput during the quarter was below nameplate capacity while the mill is in the process of ramping up and due to the shutdown in the third quarter. Costs were also higher due to the deployment of key optimizations to improve the operating availability of the plant. Unit costs are expected to decrease as throughput increases and costs stabilize.
G&A cost was $7.35 and $8.49 per tonne milled during the three and nine months ended December 31, 2024, respectively. Unit costs decreased during the quarter but remain higher than expected as the average throughput during the quarter was below nameplate capacity as the mill is in the process of ramping up as described above. Unit costs are expected to further decrease as throughput increases.

Cost of sales, excluding depreciation, during the three and nine months ended December 31, 2024, totaled $60.6 million and $115.0 million, respectively, and is net of $2.1 million and $9.6 million, respectively, of the production cost related to the in-circuit inventory that was built up during the period and is recorded in inventory as finished goods. Cost of sales includes $9.9 million and $17.4 million of royalties for the three and nine months ended December 31, 2024, respectively.

Cost of sales per ounce sold, excluding depreciation, was $1,083 and $1,035 for the three and nine months ended December 31, 2024, respectively.

Cash costs during the three and nine months ended December 31, 2024, totaled $60.4 million and $114.7 million, respectively. Cash cost per ounce sold during the three and nine months ended December 31, 2024, was $1,080 and $1,032, respectively. Cash costs exclude production costs that have been capitalized during commissioning and ramp-up efforts in advance of achieving commercial production.

AISC per ounce sold was $1,685 and $1,658 for the quarter and five months following the achievement of commercial production, respectively, with the sustaining capital expenditures totaling $33.3 million and $47.0 million that includes capitalized waste stripping and projects which are sustaining in nature in line with World Gold Council guidance. Included in sustaining capital and AISC is approximately $6.5 million for the quarter ($116 per ounce sold) and $13.0 million for the five months in the period ($154 per ounce sold), respectively, in support of the construction of the full tailings dam footprint to support the life of mine; excluding this non-recurrent capital item, AISC per ounce sold was $1,569 for the quarter and $1,504 for the five months in the period following the achievement of commercial production.

Project and capital expenditures, on an 100% and incurred basis, of $48.0 million in the fourth quarter 2024 ($382.1 million for 2024), includes:

Capital expenditures related to operations for the fourth quarter 2024 were $48.0 million ($139.8 million for 2024), including $8.3 million of capitalized stripping ($44.8 million for 2024), $12.1 million of tailings and earthworks ($49.8 million for 2024), $1.9 million of mobile equipment ($4.1 million for 2024) and $25.7 million of capital projects related to operation improvements and ramp-up ($41.1 million for 2024).
There were no project expenditures incurred in the fourth quarter. For the year, project expenditures totaled $186.1 million, including $151.7 million prior to the first gold pour on March 31, 2024, and $34.4 million following first gold to support the completion of commissioning and certain scopes of non-critical path earthwork and infrastructure.
In addition to the project expenditures, approximately $56.3 million of operating expenditures related to milling and surface costs in support of the commissioning and ramp-up efforts were capitalized during the period preceding the achievement of commercial production on August 1, 2024.
Total capital expenditures paid during the quarter, on an attributable basis, were $41.1 million ($258.5 million for 2024), which includes, on an attributable basis, the $31.0 million of sustaining and expansion capital expenditures incurred in the fourth quarter 2024 ($233.7 million for 2024) and working capital adjustments and long-term advances of $10.1 million ($24.8 million for 2024) (see "Non-GAAP Financial Measures - Sustaining and Expansion Capital Expenditures").

2025 Outlook

Production at Côté Gold is expected to be in the range of 360,000 to 400,000 ounces on a 100% basis (250,000 to 280,000 ounces on an attributable basis). The primary focus remains to build up and achieve nameplate mill design capacity of 36,000 tpd by the fourth quarter of this year, while stabilizing operations through the implementation and improvement of operating and maintenance procedures. Mining activities are expected to be relatively stable throughout the year, averaging approximately 12 million tonnes per quarter, with a declining strip ratio throughout the year as ore mined increases. Plant throughput is expected to total approximately 12 million tonnes in 2025 and achieve the steady-state nameplate throughput rate of 36,000 tpd in the fourth quarter of this year. Processing rates are expected to increase quarter over quarter, particularly in the second quarter following the winter season and the earlier than expected maintenance required on the HPGR and Vertimill (as outlined above), as well as in the fourth quarter with the installation of the additional secondary crusher. Plant head grades are expected to average approximately 1.1 to 1.2 g/t Au, as mining and stockpiling activities shift towards a more efficient mine plan to reduce rehandling of stockpiled ore and optimized for potential future expansions. Gold production is expected to be lowest in the first quarter of the year and increase sequentially as plant throughput increases throughout the year.

Cash costs are expected to be in the range of $950 to $1,100 per ounce sold and AISC to be in the range of $1,350 to $1,500 per ounce sold. The cash cost guidance reflects the cost levels experienced in the first year of operations, including higher levels of maintenance, contractor support and continuous improvement consultants. Costs are expected to be lower in the second half of the year as targeted improvements are deployed and as production increases.

Sustaining capital expenditures guidance (±5%) attributable to IAMGOLD is approximately $110 million ($157 million on a 100% basis) and continues to be higher than the life-of-mine average as the mine progresses the completion of construction of the full tailings dam footprint and related earthworks projects and incurs higher capital waste spending of approximately $20 million ($28 million on a 100% basis) to complete the final year of the initial pit pushback. Expansion capital of $15 million ($21 million on a 100% basis) is primarily associated with the planned installation of the additional secondary crusher in the fourth quarter of this year.

Exploration

The Gosselin zone is located immediately to the northeast of the Côté zone. Approximately 35,000 metres of expansion and delineation diamond drilling was originally planned for 2024, which was increased mid-year by approximately 5,400 metres, for a total completed drilling program of approximately 40,400 metres. The 2025 drilling plan entails the continuation of the ongoing diamond drilling program targeting resource conversion of Inferred Mineral Resources to Indicated in the Gosselin zone, the testing of the southern and northeastern extensions, as well as testing the breccias at depth for a total of 45,000 metres planned. In addition, 6,500 metres is planned this year to test high potential targets along the favourable structural corridor towards the Jack Rabbit area to the north-east of the Gosselin zone and develop models and targets within the larger Côté District at Swayze West - Jerome area.

On October 15, 2024, the Company provided an update on the assay results from its delineation and expansion drilling program at Gosselin with assay highlights including: 368.8 metres grading 0.96 g/t Au in drill hole GOS23-151 from 221.2 m; 235.0 metres grading 2.70 g/t Au in drill hole GOS24-160 from 697.0 m; 357.0 metres grading 1.10 g/t Au in drill hole GOS24-166 from 864.0 m; and 18.5 metres grading 12.33 g/t Au in drill hole GOS24-177 from 262.5 m (see news release dated October 15, 2024).

Technical studies are progressing to advance metallurgical testing, conduct mining and infrastructure studies to review options for potential inclusion of the Gosselin deposit into a future Côté Gold LOM plan.

Funding Agreement with Sumitomo

On December 19, 2022, the Company announced it had entered into the JV Funding and Amending Agreement with SMM ("JV Funding Agreement"), whereby SMM contributed $250.0 million of the Company's funding obligations to the Côté Gold UJV and as a result, the Company transferred 9.7% of its interest in Côté Gold to SMM (the "Transferred Interests") with a right to repurchase the Transferred Interests to return to its full 70% interest in the Côté Gold Mine.

The JV Funding Agreement also provided that until the earlier of the Company repurchasing the Transferred Interests and November 30, 2026, the Company would pay a repurchase option fee to Sumitomo equal to the three-month Secured Overnight Financing Rate ("SOFR") plus 4% on the contributions made by Sumitomo due to the Transferred Interests.

On November 30, 2024, the Company exercised its right to repurchase the 9.7% interest in Côté Gold returning IAMGOLD to its full 70% interest in Côté Gold.

The repurchase price was approximately $377 million and included $23.7 million for the repurchase option fee accrued during 2023.

The total payment of the repurchase is the aggregate amounts contributed by SMM on behalf of the Company, totaling $250.0 million, plus any incremental contributions made, and less incremental gold production received by SMM based on its increased ownership, up to achieving commercial production. SMM retained the net proceeds or payments corresponding to its increased ownership from the achievement of commercial production, as defined by the UJV agreement, up to the date of repurchase of the Transferred Interests. The UJV agreement defined the start of commercial production as the first day of the month following the period in which the mill operated at an average of 60% of the expected annual throughput over 30 days. On August 2, 2024, the Company announced commercial production at Côté Gold, thereby equating to an effective commercial production date, as defined by the UJV agreement, of September 1, 2024.

For accounting purposes, the JV Funding and Amending Agreement did not meet the requirements under IFRS to recognize the dilution of the Company's interest in the Côté UJV as a sale and the Company continued to account for 70% of the assets and liabilities of the joint venture and for 60.3% of the revenues and costs up to the repurchase date of November 30, 2024.

Following the return to 70% ownership in the Côté Gold UJV on December 1, 2024, the Company will fund 70% of the operating and capital expenditures through cash calls and receive 70% of the gold production.

Westwood delivered its highest ever annual gold production of 134,000 ounces, exceeding the top end of its 2024 production guidance range of 115,000 to 130,000 ounces due to increased production from the underground mine. Production in the fourth quarter 2024 was 35,000 ounces, higher by 7,000 ounces or 25% compared with the same prior year period, primarily due to higher grades and an increased proportion of the ore feed from the underground mine compared to the prior year period.

Mining activity in the fourth quarter 2024 of 381,000 tonnes of ore was higher by 142,000 tonnes or 59% from the same prior year period. Mining activity for the year totaled 1.02 million tonnes of ore, in line with the prior year. The underground mine averaged 1,065 tonnes per day ("tpd") as production from the underground operation continued to increase compared to the prior year in terms of both tonnes and grade, with eight active mining zones in the quarter.

Lateral underground development of 1,086 metres in the fourth quarter 2024 was lower by 177 metres or 14% compared to the same prior year period, as the mining crews can now prioritize the extraction of ore after sufficiently advancing underground development in prior periods, in line with the mine plan. Lateral underground development for the year totaled 4,591 metres, 680 metres or 13% lower than the prior year as the mining team continues to optimize the design and refine the amount of development activities required to support the mine plan.

The mining team concluded the underground rehabilitation and development work program on all existing mine areas, which has provided increased operational flexibility with multiple stope sequences available to mine concurrently at different levels and sectors of the mine. The rehabilitation work program consisted of repairing and upgrading the existing underground infrastructure following the 2020 seismic event, in line with the revised rock mechanic standard, which has been developed to ensure that safe work conditions are maintained in seismic portions of the mine. This activity enabled production to safely recommence once rehabilitation work on a specific level has been completed. The rehabilitation work program will be extended for the re-opening of previously closed mining areas within the underground mine in accordance with the mine plan.

Mill throughput in the fourth quarter 2024 was 267,000 tonnes at an average head grade of 4.34 g/t, 9% and 11% higher than the same prior year period, respectively. For the full year, mill throughput was 1.1 million tonnes at an average head grade of 4.04 g/t, 7% and 33% higher, respectively, than the prior year. The higher head grades are due to an increase in the grade from the underground mine as described above.

The mill achieved recoveries of 93% in the fourth quarter 2024, slightly lower than the same prior year period. Plant availability in the quarter of 88% was higher than the same prior year period of 78%, with the successful completion of the annual mill shutdown in November.

On January 10, 2025, the Company filed an updated NI 43-101 compliant technical report for the Westwood Mine complex detailing the results of certain mine optimization efforts and strategic assessments of the underground mine.

Financial Performance - Q4 2024 Compared to Q4 2023

Production costs of $39.0 million were lower by $0.3 million or 1% than the same prior year period primarily due to increased open pit mining activity and increased mining activity in the underground mine.

Cost of sales, excluding depreciation, of $42.3 million was in line with the same prior year period with higher milling costs resulting from repairs during November 2024 shutdown, offset by lower mining costs. Cost of sales per ounce sold, excluding depreciation, of $1,155, was lower by $291 or 20% primarily due to higher production and sales volumes.

Cash costs of $42.2 million were in line with the prior year period. Cash costs per ounce sold of $1,148 were lower by $286 or 20%, primarily due to higher production and sales volumes.

AISC per ounce sold of $1,688 was lower by $361 or 18%, primarily due to lower cash costs per ounce sold and higher production and sales volumes, partially offset by higher sustaining capital.

Sustaining capital expenditures of $18.5 million included underground development and rehabilitation of $9.7 million, mill and mobile equipment of $4.7 million, and other sustaining capital projects of $4.1 million.

2025 Outlook

Westwood production is expected to be in the range of 125,000 to 140,000 ounces in 2025, as mining activities continue the underground ramp-up towards 1,000 tpd steady-state targeting multiple active mining areas while striving to maintain relatively high grades and minimize dilution. Open pit activities from Grand Duc are currently planned to be completed by the fourth quarter of 2025, though Grand Duc stockpiled material will contribute to the mill feed into 2027. There are potential options for an accretive expansion and extension of the pit, which will be investigated this year.

Cash costs at Westwood are expected to be in the range of $1,175 to $1,325 per ounce sold and AISC in the range of $1,675 to $1,825 per ounce sold. Unit costs are expected to decrease from 2024 levels, in line with increased production levels.

Capital expenditures guidance is $70 million (±5%), primarily consisting of underground development and rehabilitation in support of the 2025 mine plan, the continued renewal of the mobile fleet and equipment overhauls, and certain asset integrity projects at the Westwood mill.

Operations

Essakane delivered full year attributable production of 409,000 ounces produced, achieving the top end of the revised guidance range of 380,000 to 410,000 ounces, with fourth quarter 2024 attributable production of 80,000 ounces, in line with expectations. Full year production is an increase of 37,000 ounces, or 10%, over the prior year primarily the result of higher grades milled and increased throughput. Compared to the same prior year period, fourth quarter production decreased by 28,000 ounces or 26%, primarily due to a decrease in the grade milled and lower tonnage due to increased downtime at the mill resulting from maintenance activities.

Mining activity totaled 12.4 million tonnes mined in the fourth quarter 2024, lower by 0.5 million tonnes or 4% compared to the same prior year period. For the full year mining activity totaled 46.9 million tonnes, 3.6 million tonnes or 8% higher than the prior year period. During the quarter, the mining fleet achieved targeted capital stripping activities intended to secure access to ore on deeper benches of Phase 7 in support of the 2025 mine plan. In the prior year period, mining activity was lower due to periodic interruptions due to supply chain constraints related to the security environment in the country.

Mill throughput in the fourth quarter 2024 was 2.9 million tonnes at an average head grade of 1.07 g/t, 5% lower and 19% lower than the same prior year period, respectively. Mill throughput for the year totaled 12.1 million tonnes at an average head grade of 1.33 g/t, 7% and 6% higher than prior year levels. Throughput was lower due to scheduled maintenance during December. Average head grades decreased in the fourth quarter compared to the first half of the year, in line with the mine plan as mining activities prioritized waste stripping sequences in support of the 2025 production plan including the opening of the upper benches of Phase 7 resulting in increased supplementation of the mill feed from available ore stockpiles.

The security situation in Burkina Faso continues to be a focus for the Company. Security-related incidents are still occurring in the country, the immediate region of the Essakane mine and, more broadly, the West African region. The security situation in Burkina Faso and its neighboring countries continues to apply pressures to supply chains, although with a reduced impact and there was no related business interruption during 2024. The Company continues to take proactive measures to ensure the safety and security of in-country personnel and is constantly adjusting its protocols and the activity levels at the site according to the security environment. The Company continues to invest in the security and supply chain infrastructure in the region and at the mine site. It is also incurring additional costs to bring employees, contractors, supplies and inventory to the mine.

Financial Performance - Q4 2024 Compared to Q4 2023

Production costs of $124.4 million were higher by $12.2 million or 11%, resulting from higher mining and milling costs arising during the period due to scheduled maintenance activities, higher realized fuel prices and higher supply chain and transportation cost impacted by the security situation. While higher than levels realized in the previous year, the landed prices of key consumables, including light fuel, cyanide, grinding media and lime remained at levels experienced over the past few quarters.

Cost of sales, excluding depreciation, of $139.7 million was higher by $5.4 million or 4% primarily due to higher production costs and higher royalties. Cost of sales per ounce sold, excluding depreciation, of $1,504 was higher by $370 or 33% primarily due to lower production and sales volumes and higher royalties. Royalties increased due to increased sales volume and higher realized gold prices.

Cash costs of $139.4 million were higher by $5.3 million or 4%, primarily due to higher cost of sales and higher royalties. Cash costs per ounce sold of $1,501 were higher by $369 or 33%, primarily due to lower production and sales volumes and higher royalties.

AISC per ounce sold of $2,118 was higher by $570 or 37% primarily due to lower production and sales volumes and an increase in sustaining capital expenditures compared to the prior period.

Total capitalized stripping of $33.1 million was higher by $0.8 million or 2%, as the mine fleet operated at full capacity and continued the strategic pushback of Phase 7 in the main pit in support of the 2025 mine plan.

Sustaining capital expenditures, excluding capitalized stripping, of $15.9 million included capital spares of $3.9 million, mobile and mill equipment of $3.3 million, tailings management of $2.7 million, resource development of $1.9 million, generator overhaul of $0.4 million, and other sustaining projects of $3.7 million. Expansion capital expenditures of $2.1 million were incurred in fulfillment of the community village resettlement commitment.

2025 Outlook

Essakane attributable production is expected to be in the range of 360,000 to 400,000 ounces (400,000 to 440,000 ounces at 100%). Mining activities are expected to complete mining in Phase 5 in the first half of the year, with the bulk of the mined material coming from Phase 6 and Phase 7. With mining moving into the primary zones of Phase 6 and 7, capitalized waste stripping is expected to be relatively lower in 2025. The mill is expected to operate at throughput and head grades in line with the current life of mine plan as per the December 2023 43-101 Technical Report.

Cash costs at Essakane are expected to be in the range of $1,400 to $1,550 per ounce sold and AISC to be in the range of $1,675 to $1,825 per ounce sold. The cost guidance for 2025 is higher than the 2024 cost guidance ranges due to lower production and higher local spending including regional security expenditures, increased community programs, permit fees and taxes. A decrease in capitalized waste mining resulted in less waste stripping costs being capitalized and therefore in a higher proportion of costs included in cash costs with an equal reduction in capitalized waste stripping costs included in AISC.

Capital expenditures guidance is approximately $115 million (±5%), including approximately $40 million on capitalized waste stripping to progress into Phases 6 and 7, as well as the ongoing replacement of certain equipment to improve efficiency and maintenance costs at Essakane.

Continued security incidents or related concerns could have a material adverse impact on future operating performance. The Company continues to actively work with authorities and suppliers to mitigate potential impacts and manage continuity of supply due to the security situation noted above while also investing in additional infrastructure and supply inventory levels appropriate to secure operational continuity.

FINANCIAL REVIEW

Liquidity and Capital Resources

As at December 31, 2024, the Company had $347.5 million in cash and cash equivalents and net debt of $859.3 million. The Company has $220 million drawn on the Credit Facility and approximately $418.5 million remains available, resulting in liquidity at December 31, 2024, of approximately $767.0 million.

Within cash and cash equivalents, $46.0 million (70% basis) was held by the Côté Gold UJV, $130.2 million was held by Essakane and $160.4 million was held in the corporate treasury. The Côté Gold UJV requires its joint venture partners to fund, in advance, two months of future expenditures and cash calls are made at the beginning of each month, resulting in the month end cash balance approximating the following month's expenditure.

On February 11, 2025, the Company completed a private placement of 0.8 million flow-through common shares of the Company (the "Flow-Through Shares") that will qualify as "flow-through shares" (within the meaning of subsection 66(15) of the Income Tax Act (Canada)). The Flow-Through shares were issued at a price of C$12.25 per Flow-Through Share for aggregate gross proceeds of C$10.0 million.

The Company uses dividends and intercompany loans to repatriate funds from its operations and the timing of dividends may impact the timing and amount of required financing at the corporate level, including the Company's drawdowns under the Credit Facility. Excess cash at Essakane is mainly repatriated through dividend payments, of which the Company will receive its 90% share, net of dividend taxes. Essakane declared a dividend during the second quarter 2024 of $180.0 million, for which the minority interest portion and withholding taxes of $28.1 million were paid during the second quarter 2024, and $136.3 million of which was received by the Company in the third quarter and the balance of $15.6 million was received in October 2024.

On November 30, 2024, the Company issued a payment of $377.7 million to complete the repurchase of the 9.7% interest of the Côté Gold Mine that was transferred to SMM through the amended Côté Gold Joint Venture Agreement, returning IAMGOLD to its full 70% interest in Côté Gold. The repurchase payment was funded through available cash balances and amounts available under the Credit Facility.

On December 23, 2024, the Company announced that it closed the sale of its 100% interest in the Karita Gold Project associated exploration assets in Guinea for gross proceeds of $35.5 million.

Restricted cash in support of environmental closure costs obligations related to Essakane, Doyon division and Côté Gold totaled $68.4 million.

Credit Facility

On December 23, 2024, the Company announced that the Company and its syndicate of lenders executed an amendment to its existing secured revolving Credit Facility, extending the maturity by four years now maturing on December 20, 2028, and an increase in the facility size from $425 million to $650 million in support of the Company's requirements for a senior revolving facility for its overall business.

The Credit Facility provides for an interest rate margin above the SOFR, banker's acceptance prime rate and base rate advances which vary, together with fees related thereto, according to the total Net Debt to EBITDA ratio of the Company. The Credit Facility is secured by certain of the Company's real assets, guarantees by certain of the Company's subsidiaries and pledges of shares of certain of the Company's subsidiaries. The key terms of the Credit Facility include certain limitations on incremental debt, certain restrictions on distributions and financial covenants, including Net Debt to EBITDA, Interest Coverage and a minimum liquidity requirement of $150 million.

As at December 31, 2024, the Credit Facility was drawn in the amount of $220 million and the Company issued letters of credit under the Credit Facility in the amount of $7.4 million as collateral for surety bonds issued, $0.4 million as guarantees for certain environmental indemnities to government agencies, and $3.7 million as a supplier payment guarantee, with $418.5 million remaining available under the Credit Facility.

5.75% Senior notes

In September 2020, the Company completed the issuance of $450 million of senior notes at face value with an interest rate of 5.75% per annum (the "Notes"). The Notes are denominated in U.S. dollars and mature on October 15, 2028. Interest is payable in arrears in equal semi-annual installments on April 15 and October 15 of each year, beginning on April 15, 2021, in the amount of approximately $12.9 million for each payment. The Notes are guaranteed by certain of the Company's subsidiaries.

The Company incurred transaction costs of $7.5 million which have been capitalized and offset against the carrying amount of the Notes within long-term debt in the consolidated balance sheets and are being amortized using the effective interest rate method.

Term Loan

In May 2023, the Company entered into the $400.0 million Term Loan. The Term Loan has a 3% original issue discount, bears interest at a floating interest rate of either one month or three-month SOFR + 8.25% per annum and matures on May 16, 2028. The Term Loan is denominated in U.S. dollars and interest is payable upon each SOFR maturity date. The Term Loan notes are guaranteed by certain of the Company's subsidiaries, subordinated to the Credit Facility.

The Company incurred transaction costs of $11.0 million, in addition to the 3% discount, which have been capitalized and offset against the carrying amount of the Term Loan within long-term debt in the consolidated balance sheets and are being amortized using the effective interest rate method.

The Term Loan can be repaid in $20 million tranches at any time and has a make-whole premium if repaid in the first two years, a 104% premium if repaid after May 2025, a 101% premium if repaid after May 2026 and 100% thereafter.

The Term Loan has a minimum liquidity requirement of $150 million and an interest coverage ratio (1.5x trailing consolidated EBITDA to consolidated interest expense) covenants and has no mandatory requirements for gold or other forms of hedging, cost overrun reserves or cash sweeps.

Leases

At December 31, 2024, the Company had lease obligations of $124.2 million at a weighted average borrowing rate of 7.33%.

On April 29, 2022, the Company, on behalf of the Côté Gold UJV, entered into a master lease agreement with Caterpillar Financial Services Limited to lease certain mobile equipment, which have been delivered through 2023 and 2024, with a value of approximately $125 million. In the second and fourth quarters 2024, the master lease agreement was amended to increase the facility to $150 million and $175 million, respectively. The increase in the facility supports additional leasing of mobile equipment at Côté Gold during 2024 and 2025.

Equipment loans

At December 31, 2024, the Company had equipment loans with a carrying value of $2.1 million secured by certain mobile equipment, with interest rates at 5.3% which mature in 2026. The equipment loans are carried at amortized cost on the consolidated balance sheets.

Gold prepay arrangements

During 2021, the Company entered into gold sale prepayment arrangements (the "2022 Prepay Arrangements"). The Company received $236.0 million in 2022 and was to physically deliver 150,000 gold ounces over the course of 2024, at an average forward contract price of $1,753 per ounce on 50,000 ounces and a collar range of $1,700 to $2,100 per ounce on 100,000 ounces.

In December 2023 and April 2024, the Company entered into further gold sale prepay arrangements and amendments to certain of the 2022 Prepay Arrangements, which effectively transitioned the cash impact of the gold delivery obligations from the 2022 Prepay Arrangements out of the first and second quarters of 2024 into the first and second quarters of 2025.

2024 Q1 Prepay Arrangements: the Company received an amount of $59.9 million during the first quarter 2024 at an effective gold price of $1,916 per ounce and is required to physically deliver 31,250 ounces of gold over the period of January 2025 to March 2025 in equal monthly amounts.
2024 Q2 Prepay Arrangements: the Company received an amount of $59.4 million during the second quarter 2024 at an effective gold price of $1,900 per ounce and is required to physically deliver 31,250 ounces of gold over the period of April 2025 to June 2025. The arrangement includes a gold collar of $2,100 to $2,925 per ounce whereby the Company will receive a cash payment at the time of delivery of the ounces if the spot price of gold exceeds $2,100 per ounce, with the payment calculated as the difference between the spot price and $2,100 per ounce, capped at $2,925 per ounce.
Amendment to the 2022 Prepay Arrangements: deferred the delivery of 12,500 ounces that were previously scheduled for delivery in the first half of 2024 to the first half of 2025. The Company will make a cash payment of $0.5 million in the first quarter 2025 and $0.6 million in the second quarter 2025 in consideration for the deferral. The production previously designated to be delivered into the deferred arrangements was sold at market rates in the first and second quarters of 2024.

The Company delivered 37,500 ounces under the 2022 Prepay Arrangements in the fourth quarter 2024 (137,500 ounces for the year) and received $10.0 million ($38.9 million for the year) in relation to the collar.

Surety bonds and performance bonds

As at December 31, 2024, the Company had (i) C$255.7 million ($177.5 million) of surety bonds, issued pursuant to arrangements with insurance companies, in support of environmental closure costs obligations related to the Doyon division and Côté Gold and (ii) C$32.0 million ($22.2 million) of performance bonds in support of certain obligations related to the construction of Côté Gold.

As at December 31, 2024, the total collateral provided through letters of credit and cash deposits for the surety and performance bonds was $18.3 million. The balance of $181.4 million remains uncollateralized for the surety and performance bonds.

During the quarter, the Company increased surety bonds to support the updated environmental closure cost obligations by C$40.2 million. The Company will be required to increase bonds further by C$19.0 million cumulatively during the second and third quarter of 2025 and C$19.0 million cumulatively during the second and third quarter of 2026.

Derivative contracts

In addition to the gold sale prepayment arrangements noted above, and in order to mitigate volatility in costs and protect against downside, the Company entered into certain derivative contracts in respect of exchange rates. In addition, the Company may manage certain other commodities exposure such as oil through derivatives. See "Market Risk - Summary of Foreign Currency and Commodity Derivative Contracts" for information relating to the Company's outstanding derivative contracts, including the derivative contracts associated with Côté Gold.

Liquidity Outlook

At December 31, 2024, the Company had available liquidity of $767.0 million mainly comprised of $347.5 million in cash and cash equivalents and $418.5 million available under the Credit Facility. Within cash and cash equivalents, $46.0 million (70% basis) was held by Côté Gold and $130.2 million was held by Essakane. Cash at Essakane is mainly repatriated through dividend payments, of which the Company will receive its 90% share, net of dividend taxes.

The Company has considerable obligations and factors impacting its liquidity projections during the next twelve months:

IAMGOLD will receive 70% of gold production and will fund 70% of the disbursements at Côté Gold related to the planned and unplanned costs related to the ramp-up, as well as ongoing operating and capital expenditures and working capital requirements. It is expected that Côté Gold will remain free cash flow positive, excluding the impact of gold prepay transactions. A slower than planned ramp-up or unplanned downtime would result in less gold sales and an increase in the net funding requirement.
The Company is required to deliver 75,000 ounces under its gold prepay arrangements from January 2025 to June 30, 2025. The prepay arrangements were funded at the time of entering into the agreements. The Company will receive cash payments at the time of delivering into the gold prepay arrangement based on the amount that market price of gold at the time of delivery exceeds $2,100 per ounce, capped at $2,925 per ounce, for 31,250 ounces that will be delivered during the second quarter 2025.

The Company's liquidity position, comprised of cash and cash equivalents, short-term investments, and availability under the credit facility, together with expected cash flows from operations, is expected to be sufficient to support the Company's normal operating requirements, capital commitments, and service the prepay and debt obligations as it becomes due.

The Company's financial results are highly dependent on the price of gold, oil and foreign exchange rates and future changes in these prices will, therefore, impact performance. The Company's ability to draw down on the Credit Facility is dependent on its ability to meet net debt to EBITDA and interest ratio covenants.

The Company will be dependent on the cash flows generated from its operations to repay its indebtedness that was incurred to fund the construction of the Côté Gold project. Readers are encouraged to read the "Caution Regarding Forward Looking Statements" and the "Risk Factors" sections contained in the Company's 2023 Annual Information Form, which is available on SEDAR at www.sedarplus.ca and the "Caution Regarding Forward Looking Statements" and "Risk and Uncertainties" section of the MD&A.

Income Statement

Revenues - Revenues were $469.9 million in the fourth quarter 2024 from sales of 185,000 ounces at an average realized gold price of $2,525 per ounce, higher by $172.3 million or 58% than the prior year period, due to higher sales volumes at Westwood, the commencement of gold sales from the Côté Gold Mine, and a higher realized gold price, partially offset by lower sales volumes at Essakane, the impact of gold deliveries into the 2022 Prepay Arrangement (defined above), including 12,500 ounces delivered at a forward price of $1,753 per ounce, and 25,000 ounces delivered into a collar with gold price participation capped at $2,100 per ounce.

Cost of sales - Cost of sales excluding depreciation was $242.6 million in the fourth quarter 2024, higher by $65.9 million or 37% than the prior year period, primarily due to the commencement of operations and gold sales at Côté Gold, the ramp-up of underground mining activity at the Westwood mine and increased royalty payments due to higher realized gold prices.

Depreciation expense - Depreciation expense was $96.4 million in the fourth quarter 2024, higher by $25.3 million or 36% than the prior year period primarily due to the commencement of operations and gold sales at the newly operating Côté Gold Mine, and the reversal of previous impairments for the Westwood mine complex in the third quarter, partially offset by lower production volumes and the amortization of deferred stripping assets at Essakane.

Exploration expense - Exploration expense was $5.7 million in the fourth quarter 2024, higher by $2.1 million or 58% than the prior year period due to increased exploration expenditures at Chibougamau District and Côté Gold.

General and administrative expense - General and administrative expense was $15.3 million in the fourth quarter 2024, higher by $3.9 million or 34% than the prior year period, primarily due to $4.9 million in restructuring costs incurred in the period, partially offset by lower salaries and accruals.

Income tax expense - Income tax expense was $34.3 million in the fourth quarter 2024, higher by $33.2 million or 3018% than the prior year period. It is comprised of a current income tax expense of $25.1 million and a deferred income tax expense of $9.2 million, higher than the prior year period for current income tax expense by $10.7 million or 74% and higher for deferred income tax expense by $22.5 million or 169%, respectively. The current income tax expense was higher primarily due to higher income in Essakane. The deferred income tax expense was higher primarily due to (i) the weakening of the XOF currency, also referred to as the West African CFA franc for Essakane's local accounting purposes and (ii) the recognition of deferred taxes related to Côté Gold mining tax.

Operating Activities

Net cash flow from operating activities for the fourth quarter 2024 was $102.6 million, higher by $32.7 million compared to the same prior year period, primarily due to: higher cash earnings of $140.2 million due to a higher realized gold price and higher sales volume; a decrease in income tax paid of $5.4 million, offset by: a decrease in trade and other payables of $31.9 million due to the timing of the supplier invoices; an increase in supplies inventories, finished goods and ore stockpiles of $9.4 million primarily due to an increase in finished goods and ore stockpiles at Côté Gold, offset by a reduction in supplies inventories and finished goods at Essakane and Westwood; a negative impact of $64.4 million from deferred revenue recognized as part of the prepay arrangements; a decrease in derivative settlements of $3.9 million.

Investing Activities

Net cash used in investing activities for the fourth quarter 2024 was $102.5 million, a decrease of $169.7 million from the same prior year period, primarily due to: a decrease in capital expenditures for property, plant and equipment of $130.9 million, mainly due to the completion of the Côté Gold construction phase; a decrease in restricted cash of $22.4 million; a decrease in capitalized borrowing costs of $10.9 million.

Financing Activities

Net cash used in financing activities for the fourth quarter 2024 was $194.9 million, a decrease of $211.8 million from the same prior year period, primarily due to: the payment made to SMM to affect the repurchase of the 9.7% Transferred Interest in Côté Gold totaling $376.9 million; a decrease in proceeds received through the SMM funding arrangement of $27.1 million; the cash option fee payment made to SMM in relation to the repurchase totaling $15.2 million; an increase in interest paid of $12.7 million, offset by: a draw of $220.0 million to the Credit Facility in the fourth quarter 2024.

Westwood Impairment Reversal

During the year, the Company assessed that the increase in the long-term consensus price of gold was an indicator of impairment reversal for the Westwood CGU, which includes the Doyon closed mine. As a result, a $455.5 million reversal of previously recorded impairments was recognized as the recoverable amount of Westwood exceeded the carrying value.

NON-GAAP FINANCIAL MEASURES

The Company has included certain non-GAAP financial measures to supplement its consolidated financial statements, which are presented in accordance with IFRS, including the following:

Average realized gold price per ounce sold
Underground mining cost per ore tonne mined, open pit net mining cost per operating tonne mined, milling cost per tonne milled, and G&A cost per tonne milled
Cash costs, cash costs per ounce sold, all in sustaining cost and all in sustaining cost per ounce sold
Net earnings (loss) attributable to shareholders and adjusted net earnings (loss) attributable to shareholders
Net cash from operating activities, before movements in working capital and non-current ore stockpiles
Earnings before interest, income taxes, depreciation and amortization ("EBITDA")
Mine-site free cash flow
Sustaining and expansion capital expenditures
Project expenditures

The Company believes that, in addition to conventional financial measures prepared in accordance with IFRS, these non-GAAP financial measures will provide investors with an improved ability to evaluate the underlying performance of the Company. Non-GAAP financial measures do not have any standardized meaning prescribed by IFRS, may not be comparable to similar measures presented by other companies 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, which, in the Company's case, are not significant and to enable investors to understand the Company's financial performance based on the average realized proceeds of selling gold production in the reporting period.

Average realized gold price per ounce sold may not be calculated based on amounts presented in this table due to rounding.
Average realized gold price per ounce sold is calculated based on sales from the Company's Côté Gold mine at 60.3% through November 2024 and 70% thereafter, and Westwood and Essakane mines at 100%.
Average realized gold price per ounce sold in the fourth quarter 2024 includes 37,500 ounces at $2,031 per ounce (137,500 ounces at $2,012 per ounce for the year) as delivered into the 2022 Prepay Arrangement (2023 - nil, 2022 - 150,000 ounces at $1,500 per ounce as delivered in accordance with the 2019 Prepay Arrangement).

Underground Mining Cost per Ore Tonne Mined, Open Pit Net Mining Cost per Operating Tonne Mined, Milling Cost per Tonne Milled, and G&A Cost per Tonne Milled

Underground mining cost per ore tonne mined and open pit net mining cost per operating tonne mined are defined as:

Mining costs (as included in production costs), that exclude capitalized waste stripping for open pit mines, less changes in stockpile balances and non-production costs as these costs are not directly related to tonnes mined, divided by
the sum of the tonnage of ore and operating waste mined.

Milling cost per tonne milled and general and administrative cost per tonne milled are defined as:

Mill and general and administrative costs (as included in production costs), excluding selling costs and non-production costs as these costs are not directly related to tonnes milled, divided by
the tonnage of ore milled.

IAMGOLD believes these non-GAAP financial performance measures provide further transparency and assist analysts, investors and other stakeholders of the Company in assessing the performance of mining operations by eliminating the impact of varying production levels. Management is aware, and investors should note, that these per tonne measures of performance can be affected by fluctuations in mining and/or processing levels. This inherent limitation may be partially mitigated by using this measure in conjunction with production costs and other data prepared in accordance with IFRS. These measures do not have standardized meanings under IFRS and may not be comparable to similar measures presented by other mining companies. They should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Cash Costs, Cash Costs per Ounce Sold, AISC and AISC per Ounce Sold

The Company reports cash costs, cash costs per ounce sold, AISC and AISC per ounce sold in order to provide investors with information about key measures used by management to monitor performance of mine sites in commercial production and its ability to generate positive cash flow.

Cash 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. AISC include cost of sales exclusive of depreciation expense, sustaining capital expenditures, which are required to maintain existing operations, capitalized exploration, sustaining lease principal payments, environmental rehabilitation accretion and depreciation, by-product credits and corporate general and administrative costs. These costs are then divided by the Company's attributable gold ounces sold by mine sites in commercial production in the period to arrive at the cash costs per ounce sold and the AISC per ounce sold.

The following tables provide a reconciliation of cash costs, AISC, cost of sales excluding depreciation per ounce sold, cash costs per ounce sold and AISC per ounce sold on an attributable basis to cost of sales as per the consolidated financial statements.

Adjustments for the consolidation of Essakane (90%) to its attributable portion of cost of sales.
Sustaining capital expenditures are expenditures required to support current production levels at a mine site and excludes all expenditures at the Company's development projects as well as certain expenditures at the Company's operating sites that are deemed expansionary in nature which result in a material increase in annual or life of mine gold ounce production, net present value, or reserves. Sustaining capital expenditures are further described below.
Corporate general and administrative costs exclude depreciation expense and one-time material severance charges.
Other costs include sustaining lease principal payments and environmental rehabilitation accretion and depletion, partially offset by by-product credits.
Cost of sales excluding depreciation per ounce sold, cash costs per ounce sold and AISC per ounce sold may not be calculated based on amounts presented in this table due to rounding.

Sustaining and Expansion Capital Expenditures

Sustaining capital expenditures are expenditures required to support current production levels at a mine site and exclude all expenditures at the Company's development projects as well as certain expenditures at the Company's operating sites that are deemed expansionary in nature which result in a material increase in annual or life of mine gold ounce production, net present value, or reserves. The distinctions between sustaining and expansion capital used by the Company align with the guidelines set out by the World Gold Council. Expansion capital is capital expenditures incurred at new projects and capital expenditures related to major projects or expansion at existing operations where these projects will materially benefit the operations. This non-GAAP financial measure provides investors with transparency regarding the capital expenditures required to support the ongoing operations at its mines, relative to its total capital expenditures.

Project Expenditures

Project expenditures at Côté represent all the project construction capital costs incurred during construction and commissioning phase of the project in line with the Côté Gold NI 43-101 technical report and include capital expenditures, right-of-use assets acquired through leases, and initial supplies inventory, less certain cash and non-cash corporate level adjustments included in capital expenditures.

EBITDA and Adjusted EBITDA

EBITDA (earnings before income taxes, depreciation and amortization of finance costs) is an indicator of the Company's ability to produce operating cash flow to fund working capital needs, service debt obligations and fund capital expenditures.

Adjusted EBITDA represents EBITDA excluding certain impacts such as changes in estimates of asset retirement obligations at closed sites, unrealized (gain) loss on non-hedge derivatives, impairment charges and reversal of impairment charges, write-down of assets and foreign exchange (gain) loss which are non-cash items and certain cash items that are non-recurring or temporary in nature as such items are not indicative of recurring operating performance. Management believes this additional information is useful to investors in understanding the Company's ability to generate operating cash flow by excluding from the calculation these non-cash amounts and cash amounts that are not indicative of the recurring performance of the underlying operations for the periods presented.

The following table provides a reconciliation of EBITDA and Adjusted EBITDA to the consolidated financial statements:

Adjusted Net Earnings (Loss) Attributable to Equity Holders

Adjusted net earnings (loss) attributable to equity holders 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 which are non-cash items and certain cash items that are non-recurring or temporary in nature as such items are not indicative of recurring operating performance. This measure is not necessarily indicative of net earnings (loss) or cash flows as determined under IFRS. Management believes this measure better reflects the Company's performance for the current period and is a better indication of its expected performance in future periods. As such, the Company believes that this measure is useful to investors in assessing the Company's underlying performance. 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 the Company.

Net Cash from Operating Activities before Changes in Working Capital

The Company makes reference to net cash from operating activities before changes in working capital which is calculated as net cash from operating activities less working capital items and non-current ore stockpiles. Working capital can be volatile due to numerous factors, including a build-up or reduction of inventories. Management believes that this non-GAAP measure, which excludes these non-cash items, provides investors with the ability to better evaluate the operating cash flow performance of the Company.

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

($ millions, except where noted)		Q4 2024			Q4 2023			2024		2023			2022

Mine-Site Free Cash Flow

Mine-site free cash flow is calculated as cash flow from mine-site operating activities less capital expenditures from operating mine sites. The Company believes this measure is useful to investors in assessing the Company's ability to operate its mine sites without reliance on additional borrowing or usage of existing cash.
