* Attributable ounces account for IAMGOLD ownership interests: Essakane – 90%; Rosebel (excluding Saramacca) – 95%, Saramacca – 66.5%; Westwood – 100%

Annual attributable gold production for Essakane was 412,000 ounces (457,000 ounces on a 100% basis), exceeding the upper end of the updated guidance range of 390,000 to 400,000 ounces, as the mine continued to benefit from the mill debottlenecking project completed earlier in the year. In the fourth quarter, attributable production was 98,000 ounces based on a record mill feed of 3.3 million tonnes at a head grade of 1.13 grams per tonne gold (‘g/t Au’) and improved gold recoveries of 91% as mining activities moved into lower graphitic ore zones.

Annual attributable gold production for Rosebel was 154,000 ounces (188,000 ounces on a 100% basis), at the upper end of the updated guidance range of 140,000 to 160,000 ounces. In the fourth quarter, attributable production was 42,000 ounces based on total mill feed of 2.4 million tonnes at an average head grade of 0.78 g/t Au and average recovery of 86%. Mining activities saw the Rosebel pits contribute 1.16 million ore tonnes with a strip ratio of 8.1 (waste to ore), and Saramacca contribute 1.03 million ore tonnes with a strip ratio of 2.1 (waste to ore). Efficiency improvements of the carbon adsorption/desorption circuit were completed at the end of the fourth quarter, with further improvements in the drawdown from gold-in-circuit expected in the first quarter of 2022.

Annual gold production for Westwood was 35,000 ounces, at the lower end of updated guidance of 35,000 to 45,000 ounces, following the restart of underground operations in June 2021. In the fourth quarter, the operations produced 13,000 ounces, as ore production from Westwood underground ramped up and resulted in a higher average head grade of 1.83 g/t Au. Mill feed totaled 254,000 tonnes and gold recoveries were 90%. Although underground mine productivity is improving, the pace of the ramp up remains cautious in keeping with the safety-first culture of IAMGOLD, as the Company continues to prioritize the implementation of enhanced ground support and additional safety measures, coupled with continued pressures associated with general labour shortages in the region.

The Company’s consolidated cash costs and consolidated AISC for its three operating mines are expected to be between the 2021 updated guidance ranges of $1,115 and $1,150 per ounce sold and $1,395 and $1,435 per ounce sold, respectively, excluding the impact of potential net realizable value adjustments on long term stockpiles. Long term stockpiles include historic costs which relate to ore mined in prior periods not expected to be processed in 2022. Capital expenditures for 2021 are expected to come in line with expectations, with Côté Gold preliminary spending in the fourth quarter estimated at $147 million, comparing well with guidance estimates of $150 million.

IAMGOLD ended 2021 with approximately $545 million in cash and cash equivalents, $42 million in restricted cash, $8 million in short term investments and $498 million in its undrawn credit facility.

COVID-19 Response

The global COVID-19 pandemic continues to evolve. Despite widespread mass immunization programs intended to limit the effect of the virus in many countries, including Canada and Suriname, the emergence of new variants, such as the new Omicron variant, has been causing rates of infection to rapidly increase again globally. The Company continues to closely monitor developments and is taking necessary measures to manage the impact of the COVID-19 pandemic on its personnel, operations, construction and development projects and exploration activities. The previously implemented protocols remain in place at our sites and are reviewed on an ongoing basis to adapt to the evolving situation.

2022 Guidance

IAMGOLD’s operational guidance for 2022 is as follows:

  • Attributable gold production of 570,000 to 640,000 ounces;
  • Cash costs1 between $1,100 and $1,150 per ounce sold;
  • AISC1 between $1,650 and $1,690 per ounce sold. Sustaining capital expenditures have increased due to a higher proportion of stripping costs categorized as sustaining capital due to the particular areas that are mined and the stage of the mine’s life to align with World Gold Council guidelines;
  • Sustaining capital expenditures1 of $310 million (± 5%) of which the majority is related to capital waste stripping and underground development;
  • Côté Gold expenditures of between approximately $590 to $620 million;
  • Other expansion capital expenditures1 (ex-Côté Gold) of approximately $70 million (± 5%) including approximately $20 million at Boto Gold project; and
  • Exploration expenditures of approximately $35 million, including near-mine and greenfield programs.

Notes: Figures may not add due to rounding. The 2022 guidance is based on the following full year assumptions: USD:CAD exchange rate of 1.25 (Côté 2022 capital expenditures assumes USD:CAD of 1.30), EUR:USD exchange rate of 1.20 and average crude oil price of $70 per barrel.
* Attributable ounces and capital expenditures account for IAMGOLD ownership interests: Essakane – 90%; Rosebel (ex-Saramacca) – 95%, Saramacca – 66.5%; Westwood – 100%; The Company owns 64.75% of Côté Gold and is contributing 70% of the Côté Gold joint venture capital expenditures.

In 2022, Essakane attributable gold production is forecast 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. Cash costs are expected to increase slightly due to increased cost pressures and additional security measures. The increase in AISC reflects the increase in operating costs, as well as higher sustaining capital and capitalized waste stripping. Sustaining capital expenditures of $165 million include capitalized waste stripping, while expansion capital expenditures are expected to reduce accordingly to approximately $5 million. Looking beyond 2022, Essakane is expected to continue to produce in the range of 325,000 ounces and 375,000 ounces in each of 2023 and 2024.

In 2022, Rosebel attributable gold production is forecast 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 and as a result of expected increased recoveries from continuing refurbishment initiatives at the mill complex. Sustaining capital expenditures of $105 million include capitalized waste stripping, tailings facility expansion and maintenance. Expansion capital of $35 million includes the completion of non-critical path items related to Saramacca and investments in the processing facility. Looking beyond 2022, Rosebel is expected to produce 180,000 to 200,000 of attributable gold ounces in 2023 and 2024. The Company has completed an updated Mineral Resource and Mineral Reserve estimate and life-of-mine plan for Rosebel, details of which are outlined below in the section titled ‘Rosebel Update’.

In 2022, gold production at the Westwood complex is forecast to be in the range of 55,000 to 75,000 ounces, assuming the safe re-start of two additional underground zones (Central and West). Production levels are expected to increase each quarter benefitting from the continued ramp-up of underground mining activities and increasing grade from the adjacent Grand Duc open pit. Looking beyond 2022, the Company is continuing to evaluate potential strategic alternatives for Westwood, while ramping up mining activities and development, balanced with the need for the ground support activities implemented in 2021. The additional development and resumption of mining in the Central and West zones are expected to allow for the Westwood complex to ramp up to the 90,000 to 100,000 ounce per year production level with corresponding improvements in cost profile.

Fourth Quarter and Full Year 2021 Financial Results

A conference call will be held on Thursday, February 24, 2022, at 8:30 a.m. (Eastern Time) for a discussion with management regarding IAMGOLD’s 2021 fourth quarter and full-year operating performance and financial results.

CÔTÉ GOLD – FOURTH QUARTER PROJECT UPDATE

Project Activities

In December 2021, the Company announced the appointment of Jerzy Orzechowski as Executive Project Director for Côté Gold. Mr. Orzechowski is a senior executive specializing in project development, management, engineering, construction and strategic planning with 40 years of experience working in various project execution strategies (EPC, EPCM, joint ventures, turn-key) and in all phases of large capital projects implementation and execution. His wealth of experience with large projects will be invaluable in bringing Côté Gold through construction completion to production. The management of the project now reports to Mr. Orzechowski and he reports directly to the CEO and is involved in the oversight by the Côté Project Review Committee of the Board.

As of December 31, 2021, detailed engineering reached approximately 92.2% with plant civil and concrete deliverables principally completed and mechanical, piping, electrical and instrumentation continuing into the first quarter of 2022. Overall the Project was approximately 43.4% complete. The following provides an update on project activities for the fourth quarter of 2021:

Project Activity Q4 2021 Update
Health and safety The Project surpassed 3.4 million hours with no lost time injuries. Our COVID-19 monitoring programs, including antigen, PCR and sewage testing, remain robust and we continue to assess site protocols in view of the emergence of the Omicron variant. The return of the workforce from the holiday period is being structured to adjust ramp up and permit close monitoring of the Omicron variant threats. Improvements in vaccination rates on site continued.
Earthworks activities Earthwork activities continued with the main focus on ensuring major infrastructure for 2022 freshet are in place. Water realignment channel work continued. Clam Lake Dam #1 and #2 are now complete. Work on New Lake South Dam final lifts was completed prior to the end of the year and New Lake North Dam is progressing well. Tailings management facility starter dam foundation excavation commenced as planned in early December.
Mining activities Overburden pre-stripping in the pit is advancing and during the period access to fresh rock was achieved to the east. The first ore blast was taken in October 2021 in the southern area of the pit and mining activities broke through elevation 382 throughout several areas of the pit – a significant milestone achieved for the project.
Processing plant Processing facility structural steel erection, which commenced in mid-October, has completed all major lifts with only a minor part of in-fill steel remaining to be erected for the high-bay grinding section of the building. Wall panel cladding installation has started with approximately 32% completed at quarter end. The Company remains on track for process building enclosure by the end of the first quarter of 2022. Other civil works associated with the processing facility including the HPGR/secondary crusher building and primary crushing building were completed during the quarter. The primary crusher feeder frames, chutes and associated supports are now on site. Fabrication of conveyors is progressing well with delivery as sections are completed. Major components of the ball mill such as motor, chillers and shells are progressing well and elements have started shipping.
Other activities and
supply chain
Permanent camp commissioning is complete providing, along with the construction camp, a total of 1388 rooms. The project averaged approximately 800 workers at site prior to the ramp down for the holidays. The permanent potable water treatment plant has been commissioned and the camp is planning to switch to grid power early in the new year. Work on the 42 kilometer 115KV power line has started with tree clearing.
Equipment delivery is ongoing and inventory on site continues to increase. We continue to closely monitor global logistics risks and, at this time, are not expecting material impacts on the project schedule, although challenges in the global supply chain persist which may be amplified by impacts from the current Omicron wave.
Permitting and
sustainability
The Company secured a number of key operations phase permits during the quarter, including the provincial Environmental Compliance Authorization for operations, the key remaining permit, the permit to take water and permits required to support the construction of the transmission line. Community consultations and ongoing implementation of the impact benefit agreements signed with indigenous partners continue. Remaining, non-critical path, minor permits are expected to be received during the remainder of the project.
Operational
readiness
Operational readiness continued to advance mainly focused on organizational design, and hiring, and initiation of training programs which are expected to ramp up in the first quarter of 2022. Other key activities included the ongoing work related to the identification of spare parts requirements for critical equipment and procurement strategies for key consumables.

Project Expenditures

At the end of the fourth quarter 2021, 87% of procurement and 79% of contracts packages have been awarded. The Company incurred $119 million and expended $147 million in project costs (at an average recorded USDCAD exchange rate, excluding the impact of hedges, of 1.27) in the fourth quarter of 2021 and expended $412 million (at an average recorded USDCAD exchange rate of 1.26) since July 1, 2020, including capital expenditures summarized in the table below and non-capital project costs.

Although to the end of the fourth quarter 2021, no material delays due to the COVID-19 pandemic have been experienced at site, cases in Ontario and other provinces have risen rapidly into January 2022. The schedule and timing of expenditures going forward do not account for any potential delays or disruptions caused by the COVID-19 pandemic, including potential impacts on timing of activities, availability of workforce and productivity, supply chain and logistics.

Other Developments in the Fourth Quarter 2021

The Company reported in October 2021 an initial mineral resource estimate for the Gosselin deposit (on a 100% basis using a US$1,500 per ounce gold price) of 124.5 million tonnes of indicated resources averaging 0.84 grams of gold per tonne for 3.35 million ounces of gold and 72.9 million tonnes of inferred resources averaging 0.73 grams of gold per tonne for 1.71 million ounces of gold. This represents a 33% increase in total contained gold at Côté Gold in measured and indicated resource categories to 13.55 million ounces and a 45% increase in total contained gold in the inferred resources category to 5.5 million ounces. The Gosselin deposit has only been drilled to approximately half of the depth of the Côté Gold deposit and remains open at depth and along strike. This demonstrates the long-term district scale potential and the exploration upside of the Project. Please refer to the Company’s news release dated October 18, 2021 for further details.

ROSEBEL UPDATE

The Company is reporting an updated Mineral Reserves estimate for Rosebel (on 100% basis) of 3.8 million ounces of gold and an updated Measured and Indicated Mineral Resources estimate (on a 100% basis and including Mineral Reserves) of 6.3 million ounces of gold as of December 31, 2021. 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.

Over the last two years, Rosebel has encountered certain challenges that have resulted in delays in stripping, strategic pit pushbacks, maintenance and the completion of required infrastructure at Saramacca. The Rosebel 2022 LOMP requires material capital investment in 2022 and 2023 to implement projects and initiatives aimed at redressing some of these challenges. As a result of the Company’s current capital allocation prioritization, the Company is commencing a strategic review process to evaluate options for Rosebel.

The Rosebel 2022 LOMP is supported by the updated Mineral Reserves and Resources estimates as at December 31, 2021 contained in this news release. The Rosebel technical results will be incorporated in a new technical report titled ‘Technical Report on the Rosebel Gold Mine, Suriname’ (the ‘Rosebel Technical Report’) prepared by Rosebel Gold Mines N.V. (‘RGM’), a subsidiary of the Company, in collaboration with WSP Global Inc. (‘WSP’) and SRK Consulting (Canada) Inc. (‘SRK’) in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (‘NI 43-101’). The Rosebel Technical Report will be filed on SEDAR within 45 days of this news release and readers are encouraged to read the Rosebel Technical Report in its entirety, including all qualifications, assumptions and exclusions that relate to the details summarized in this news release.

Rosebel 2022 LOMP

The Rosebel 2022 LOMP is based on revised geological models incorporating further drilling results for the Rosebel and Saramacca deposits, accounts for cost increases and is conservatively constrained given the other capital requirements of the Company at the present time. Two of the key priorities for Rosebel relate to stripping and mill capacity to treat hard rock. Considerable stripping is required to access deep, higher grade ore in existing pits resulting in the necessity for a material capital outlay in the next five years. The capacity for the mill to deal with the Rosebel ore hardness could be alleviated by the replacement and expansion of two crushers at an estimated cost of approximately $30 million.

Various additional value-accretive scenarios were reviewed in connection with completing the Rosebel 2022 LOMP, including the acceleration of the investment in the comminution circuit, expansion of the mining fleet to accelerate stripping and access to higher grade ore, the advancement of throughput expansion opportunities within the processing facility, and the achievement of certain productivity and costs optimization opportunities. These scenarios assumed additional available capital and demonstrated material potential opportunities to improve the economics of the operations. Further, Rosebel is located in a geologically endowed region for gold with potential for further discovery through increased investment in exploration.

The mining rate in the Rosebel 2022 LOMP is estimated at a rate of 59 million tonnes per year in 2022 and steadily increases to a rate of 64 million tonnes per year from the Rosebel and Saramacca pits until 2026 through a period of increased stripping. From 2027 the mining rate will further increase to 73 million tonnes per year with additional loading and hauling units and will start to decline from 2031 as pits are mined out.

Appendix ‘A’ to this news release outlines the Rosebel 2022 LOMP schedule including mining, stripping ratio, milling, head grades and capital and operating costs. The table below provides a summary of the key operating parameters for the Rosebel 2022 LOMP on a 100% basis:

Capital Costs

Capital costs include capitalized waste stripping, resource development costs, other sustaining capital expenditures (including mine equipment additions and replacements, tailings facility expansion) and expansion capital (including the crusher upgrades and completion of the development of Saramacca). A total of $1.24 billion of capital expenditures is estimated for the remaining 12 years of mine life, which equates to $11.70 per tonne milled or $374 per ounce produced.

Operating Costs

Average mine operating cost (inclusive of waste stripping) over the mine life is estimated at $2.70 per tonne mined based on assumed diesel costs: 2022 at $0.71 per liter, 2023 at $0.67 per liter, 2024-2033 at $0.66 per liter. The average total milling cost (inclusive of power) is estimated to be $10.51 per tonne milled. Mill consumables have seen significant increases, as increased hard rock ratios are expected to translate to an increase in power and grinding media consumption, while the addition of saprolite and laterite from Saramacca to the mill has increased cyanide and lime consumption. The average general and administrative cost is estimated at $4.37 per tonne milled and assumes an average annual spend of $38 million.

Mineral Reserves

The updated Mineral Reserves estimate for Rosebel and Saramacca (on 100% basis using $1,300 per ounce gold price) is 109 million tonnes comprised of Proven and Probable reserves and existing stockpiles at an average grade of 1.1 g/t Au for 3.8 million ounces of contained gold as of December 31, 2021, a decrease of 20% in terms of contained ounces from the prior update (refer to Company press release dated February 17, 2021).

Notes:

  • CIM (2014) definitions were followed for Mineral Resources.
  • Attributable ounces calculated as 95% for Rosebel (excluding Saramacca) and 66.5% for Saramacca.
  • Mineral Resources are estimated at a cut-off grade which varies between 0.18 and 0.54 g/t Au depending on material type and pit. Mineral Resources are estimated using an average long-term gold price of US$1,500/oz.
  • Mineral Resources are constrained by Whittle optimized pit shells using economic parameters consistent with those used for Mineral Resources estimates in the Rosebel Technical Report.
  • A minimum mining width of 5m was used for 2021.
  • Bulk density is estimated by Ordinary Kriging (OK) by weathering type except for PC – RB – MA which is a mean value based on SG dataset.
  • Mineral Resources are inclusive of Mineral Reserves.
  • Mineral Resources that are not Mineral Reserves do not demonstrate economic viability.
  • Numbers may not add due to rounding.

The Measured and Indicated Resources estimate for the Rosebel deposits and Saramacca decreased by 3.1 million ounces and 160,000 ounces, respectively, from the end of 2020 to the end of 2021. The decrease in mineral resources at Rosebel is attributed to: 2021 production depletion; a revised optimization methodology incorporating fixed cost distribution (versus dynamic cost accounting used previously); changes to the cost model which translated in an increase in mining, processing and general and administrative costs; and an updated resource block model incorporating the results of infill and conversion drilling programs completed in 2021 and applying a different block model interpolation methodology (Ordinary Kriging versus Uniform Conditioning).

The net result was the reduction in both size and depth of resource and reserve pit shells, notably Royal Hill and Pay Caro, with some ore zones excluded in the pit shells (at $1,500/oz) that could re-enter the mine plan in the future under different financial conditions and commodity price assumptions.

Impairment

In accordance with IFRS, the Company has been reviewing the carrying amount of the Rosebel cash generating unit and, based on preliminary analysis, is estimating a potential non-cash asset impairment charge to be recorded in its year-end financial results.

NON-GAAP FINANCIAL MEASURES

This news release contains non-GAAP financial measures, including cash costs per ounce sold (‘COC’), AISC per ounce sold, sustaining and expansion capital expenditures, average realized gold price and available liquidity. The Company believes that, in addition to conventional financial measures prepared in accordance with IFRS, certain investors use these non-GAAP financial measures to assess the performance of the Company. These 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.

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 COC and AISC per ounce sold. The Company believes that the use of COC and AISC per ounce sold metrics will assist analysts, investors and other stakeholders of the Company in assessing its operating performance and its ability to generate free cash flow.

The Company presents its sustaining capital expenditures in its all-in sustaining costs to reflect the capital related to producing and selling gold from its mine operations. 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.

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING DISCLOSURE OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

The mineral resource and reserve estimates contained in this news release have been prepared in accordance with NI 43-101. These standards are similar to those used by the United States Securities and Exchange Commission (the ‘SEC’) Industry Guide No. 7, as interpreted by the SEC staff. However, the definitions in NI 43-101 differ in certain respects from those under Industry Guide 7. Accordingly, mineral resource and reserve information contained in this news release may not be comparable to similar information disclosed by United States companies. Under the SEC’s Industry Guide 7, mineralization may not be classified as a ‘reserve’ unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

As a result of the adoption of amendments to the SEC’s disclosure rules (the ‘SEC Modernization Rules’), which more closely align its disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and which became effective on February 25, 2019, the SEC now recognizes estimates of ‘measured mineral resources’, ‘indicated mineral resources’ and ‘inferred mineral resources.’ In addition, the SEC has amended definitions of ‘proven mineral reserves’ and ‘probable mineral reserves’ in its amended rules, with definitions that are substantially similar to those used in NI 43-101. Issuers must begin to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021, though Canadian issuers that report in the United States using the Multijurisdictional Disclosure System (‘MJDS’) may still use NI 43-101 rather than the SEC Modernization Rules when using the SEC’s MJDS registration statement and annual report forms.

United States investors are cautioned that while the SEC now recognizes ‘measured mineral resources’, ‘indicated mineral resources’ and ‘inferred mineral resources’ under the SEC Modernization Rules, investors should not assume that any part or all of the mineral deposits in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility. Under Canadian regulations, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in limited circumstances.

Investors are cautioned not to assume that any ‘measured mineral resources’, ‘indicated mineral resources’, or ‘inferred mineral resources’ that the Company reports in this news release are or will be economically or legally mineable. Further, ‘inferred mineral resources’ have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that any part or all of an inferred mineral resource will ever be upgraded to a higher category.

The mineral reserve and mineral resource data set out in this news release are estimates, and no assurance can be given that the anticipated tonnages and grades will be achieved or that the indicated level of recovery will be realized.
