# lAMGOLD Reports Mineral Resources and Reserves for the Year Ended 2025 Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/lamgold-reports-mineral-resources-and-reserves-for-the-year-ended-2025--a49dd5e0-ed2d-4203-9643-9c932c248e0f Original source: https://money.tmx.com/en/quote/IMG/news/7553918133800361/lamgold-reports-mineral-resources-and-reserves-for-the-year-ended-2025 Publisher: tmx Original announcement: 2026-02-17T22:59:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: IAMGOLD Corporation - Ticker: IMG - Exchange: TSX - Region: Unavailable - Primary commodity: Gold - Secondary commodities: None reported - Document categories: Resource update - Extracted: 2026-09-12 07:12:11 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary IAMGOLD reported its year-end 2025 Mineral Resources and Reserves, showing a 16% increase in Measured and Indicated \(M&I\) gold resources to 31.0 million ounces, driven by resource conversion at Côté Gold and Nelligan, and new acquisitions. However, Proven and Probable \(P&P\) gold reserves decreased by 7% to 9.9 million ounces, primarily due to depletion and grade adjustments at Côté Gold and Essakane, partially offset by increases at Westwood. The update highlights both growth in resource base and challenges in reserve replacement, with some grade dilution noted across key assets. Reasoning: IAMGOLD reported its annual Mineral Resources and Reserves update, showing a significant increase in Measured and Indicated resources due to resource conversion and acquisitions, but a decrease in Proven and Probable reserves. Several deposits experienced grade declines, some offset by lower cut-off grades, indicating a mixed outcome for the year. - Positive factor: Category Upgrade - Positive factor: Tonnage Growth - Positive factor: Contained Metal Growth - Positive factor: QP/CP Signed - Positive factor: NI 43-101 Compliant - Negative factor: Tonnage Decline - Negative factor: Grade Decline - Negative factor: Cut-off Lowered - Negative factor: Dilutive Growth Facts used in scoring: 31 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: Measured and Indicated Mineral Resources increased 16% to 31.0 million ounces of gold in 1.0 Bt at 0.94 g/t Au. Evidence · text > Measured and Indicated \("M&I"\) Mineral Resources \(100% basis\) increased 16% to 31.0 million ounces of gold in 1.0 Bt at 0.94 g/t Au **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: Measured and Indicated Mineral Resources increased 16% to 31.0 million ounces of gold. Evidence · text > Measured and Indicated \("M&I"\) Mineral Resources \(100% basis\) increased 16% to 31.0 million ounces of gold **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: The increase in M&I resources was primarily associated with the conversion of Inferred Mineral Resources in the Gosselin deposit at Côté Gold and Nelligan deposit. Evidence · text > The increase was primarily associated with the conversion of Inferred Mineral Resources in the Gosselin deposit at Côté Gold and Nelligan deposit **Tonnage Decline** Polarity: negative Definition: Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down. Why it applies: Proven and Probable Mineral Reserves decreased 7%, or 796,000 ounces, from the year prior, primarily due to depletion at Côté Gold and Essakane. Evidence · text > P&P Mineral Reserves decreased 7%, or 796,000 ounces, from the year prior, primarily due to depletion at Côté Gold and Essakane **Contained Metal Decline** Polarity: negative Definition: Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain. Why it applies: Proven and Probable Mineral Reserves decreased 7%, or 796,000 ounces, from the year prior. Evidence · text > P&P Mineral Reserves decreased 7%, or 796,000 ounces, from the year prior **Grade Decline** Polarity: negative Definition: Average grade fell below the red-flag bound vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling. Why it applies: Essakane M&I Mineral Resources saw a 26% decrease in grades \(to 0.91 g/t Au, including stockpiles\). Evidence · text > a 26% decrease in grades \(to 0.91 g/t Au, including stockpiles\) **Cut-off Lowered** Polarity: negative Definition: Cut-off grade reduced beyond the suspicious bound vs prior estimate — tonnage growth may be artificial inflation. Why it applies: Westwood \(underground\) Mineral Reserves cut-off grade was reduced to 6.40 g/t Au \(down from 6.82 g/t Au previously\). Evidence · text > reduction in the underground cut-off grade to 6.40 g/t Au \(down from 6.82 g/t Au previously\) **Dilutive Growth** Polarity: negative Definition: Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion. Why it applies: Essakane M&I Mineral Resources increased 50% in tonnes but saw a 26% decrease in grades, indicating a dilutive expansion. Evidence · text > a 50% increase in tonnes \(to 150 Mt\) offsetting a 26% decrease in grades \(to 0.91 g/t Au, including stockpiles\) **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The Mineral Resources and Mineral Reserves statement was prepared in accordance with National Instrument 43-101.

Evidence · text > Christine Beausoleil, P.Geo., Senior Director, Mining Geology, IAMGOLD Corporation is the "qualified person" for the purposes of NI 43-101 \("QP"\) with respect to the mineralization being reported on and is responsible for the review and approval of all Mineral Resources estimates for IAMGOLD. Adrienne Rispoli, P.Eng., Senior Director, Mining & Integrated Planning, IAMGOLD Corporation is the QP for the purposes of NI 43-101 with respect to the mineralization being reported on and is responsible for the review and approval of all Mineral Reserves estimates for IAMGOLD. **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: The Chevrier Mineral Resources were estimated as of September 23, 2022, and Philibert Mineral Resources as of September 22, 2023, making them over two years old relative to the December 31, 2025 effective date.

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.
