IAMGOLD Files Updated Technical Report for Essakane Gold Mine

18.12.2023 | 13:00 Uhr | Newsfile
Toronto, Dec. 18, 2023 - IAMGold Corp. (NYSE: IAG) (TSX: IMG) ("IAMGOLD" or the "Company") is pleased to announce the filling of a Technical Report (the "Technical Report") for the Company's Essakane Gold Mine ("Essakane"), located in Burkina Faso. The primary objective of the Technical Report is to provide an updated Mineral Resource and Mineral Reserve ("MRMR") estimate and an accompanying updated life of mine ("LOM") plan for Essakane. The Technical Report was prepared in accordance with the disclosure requirements of National Instrument 43-101 ("NI 43-101") and has an effective date of September 30, 2023. The Technical Report is available on SEDAR at www.sedarplus.ca and on the Company's website at www.iamgold.com.

Highlights of updated Technical Report

  • Mine life extension to 2028, mining will occur from three remaining pit phases in the Essakane Main Zone ("EMZ") pit, and the Lao and Gourouol satellite pits
  • Overall production of 2.4 million ounces of gold ("oz Au") from 2023 to 2028, with an annual average gold production of approximately 400,300 oz Au during this period
  • Average estimated operating costs over the LOM (2023-2028) $32.49/t milled net of capitalized waste stripping ("CWS") (excluding CWS and stockpile movements, with CWS being transferred to sustaining capital)
  • Capital expenditures over life of mine estimated at $502.7 million (including 2023)
  • Mineral Reserve estimate from the open pit increased 21% to 1.9 million ounces at an average grade of 1.32 g/t
  • Mineral Resource estimate from the open pit increased 37% to 3.1 million ounces at an average grade of 1.40 g/t

"As one of the top gold producing mines in West Africa, Essakane continues to be an integral part of IAMGOLD," commented Renaud Adams, President and Chief Executive Officer of IAMGOLD. "The filing of the updated Technical Report today demonstrates the successes our teams have had within the fence delineating additional ounces which have increased our mineral resource inventory and more than offset mine production depletion in 2023. As a result, we have been able to extend the mine life of Essakane an additional year, providing visibility for the next five years of operations at the project."

Life of Mine Plan

The mine life is forecast from 2023 to 2028, averaging 400,300 oz Au/year with a total production of 2.4 Moz Au over the production period. The LOM plan is based on the completion of five different mining phases:

  • EMZ: three phases, Phases 5, 6, 7. Represents 87% of the gold to be mined in the LOM plan. Phase 5 is the current north phase of the EMZ pit, and the main source of ore at the Report effective date. Phase 6 is the final push back for the south part of the EMZ pit. Phase 7 is the final push back for the north part of the EMZ pit, and represents an extension of Phase 5 on the eastern wall of the EMZ pit;
  • Gourouol: located to the north of the EMZ pit;
  • Lao: located to the south of the EMZ pit, and accounts for 12% of the gold to be mined in the LOM plan.

The Essakane processing plant has a process rate limit of 12.19 Mtpa of hard rock equivalent. The 2024 LOM plan assumes a processing throughput capacity of 13.05 Mtpa. This is achieved by ensuring a minimum of 1.1 Mtpa of softer transition and saprolite ore will be fed to the process plant. The updated LOM plan no longer incorporates the investment, construction and operation of a heap leach facility following the successful demonstration of the capability of the plant to process a portion of the stockpiles that were designated for heap leaching through the existing facilities.

The political and security environment remains volatile in the Sahel region of Burkina Faso, particularly in the area where the mine is located. Terrorist-related incidents continue unabated in the country, the immediate region of the Essakane mine and, more broadly, the Sahel region of West Africa. IAMGOLD 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.


IAMGOLD is an intermediate gold producer and developer based in Canada with operating mines in North America and West Africa.
