Summary
IAMGOLD Corporation announced its updated Mineral Resources and Mineral Reserves as of December 31, 2025. The company reported a 7% decrease in Proven and Probable Mineral Reserves to 9.9 million ounces of gold, primarily due to depletion at Côté Gold and Essakane. Conversely, Measured and Indicated Mineral Resources increased by 16% to 31.0 million ounces, driven by resource conversion at Gosselin and Nelligan, and the acquisition of the Philibert and Chevrier deposits.
Reasoning: IAMGOLD reported a mixed update with a decrease in overall gold reserves due to depletion, but a significant increase in Measured and Indicated resources driven by resource conversion and new acquisitions. While the resource base expanded, some projects showed dilutive growth with lower grades, and cut-off grade changes were varied. The inclusion of new projects and resource upgrades are positive for future potential, but reserve depletion is a near-term concern.
Positive factors
- Significant increase in Measured and Indicated Mineral Resources (16% or 4.3 million ounces) driven by conversion of Inferred resources and new acquisitions.
- Acquisition of Philibert and Chevrier deposits adds new resources to the portfolio.
- Category upgrades from Inferred to Indicated at Gosselin (Côté Gold) and Nelligan improve resource confidence.
- Overall M&I resource base positions the company among the largest gold endowments for mid-tier producers.
Negative factors
- Overall Proven and Probable Mineral Reserves decreased by 7% (796,000 ounces) primarily due to depletion.
- Average grade of total M&I resources decreased by 5% and total P&P reserves decreased by 2%.
- Some M&I resource increases (Essakane, Westwood) are dilutive, with significant tonnage growth but lower average grades.
- Côté Gold reserves cut-off grade increased, potentially reducing economic material.
- Diakha-Siribaya resources are unchanged and the sale agreement for the project expired, indicating uncertainty.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
