IAMGOLD REPORTS FOURTH QUARTER AND YEAR-END 2024 RESULTS

All monetary amounts are expressed in U.S. dollars, unless otherwise indicated.

Toronto, Ontario, 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."

HIGHLIGHTS:

Operating and Financial

  • Attributable gold production for the year was 667,000 ounces, the mid-point of the Company’s increased production guidance of 625,000 to 715,000 ounces. Fourth quarter attributable production was 177,000 ounces.

1. 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).

1. 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.

2. 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.

2. Capital expenditures guidance (±5%).

3. 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").

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 rampup 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”).
