## Minestarters Atlas summary

Alamos Gold reported a significant 32% increase in global Proven and Probable gold reserves to 15.9 million ounces, with grades also increasing by 5% to 1.87 g/t Au, as of December 31, 2025. This growth was largely driven by a 125% increase in high-grade reserves at Island Gold and a 56% increase at Magino, reflecting successful conversion of resources to reserves. Global Measured and Indicated resources also grew by 6% to 5.5 million ounces, while Inferred resources decreased by 63% due to these conversions.

Reasoning: Alamos Gold reported a substantial 32% increase in global Proven and Probable gold reserves to 15.9 million ounces, accompanied by a 5% increase in overall grades, primarily driven by a 125% growth in high-grade reserves at Island Gold. This significant growth, coupled with successful resource conversion and an increased exploration budget, indicates strong operational performance and future potential, despite a decrease in Inferred resources due to conversion.

- Positive factor: Global Proven and Probable gold reserves increased significantly by 32% to 15.9 million ounces, with overall grades increasing by 5% to 1.87 g/t Au.

- Positive factor: Island Gold's high-grade Mineral Reserves more than doubled, increasing 125% to 5.1 million ounces at 10.61 g/t Au, driven by successful resource conversion.

- Positive factor: Magino's Mineral Reserves increased 56% to 3.1 million ounces, primarily due to successful resource conversion.

- Positive factor: Global Measured and Indicated Mineral Resources increased 6% to 5.5 million ounces, with slightly higher grades, indicating growth and de-risking.

- Positive factor: Successful conversion of Inferred Mineral Resources to higher confidence categories \(M&amp;I and Reserves\) at Island Gold and Magino.

- Positive factor: The company increased its gold price assumptions for estimates, reflecting a stronger market environment.

- Positive factor: A record global exploration budget of $97 million is planned for 2026, indicating strong future growth potential.

- Negative factor: Global Inferred Mineral Resources decreased by 63% to 2.0 million ounces, with grades decreasing by 37%, reflecting conversion but also a reduction in the lowest confidence category.

- Negative factor: Mulatos Mineral Reserves decreased by 14% due to depletion at La Yaqui Grande.

- Negative factor: The cut-off grade for La Yaqui Grande reserves is described as a 'net of process value' rather than a simple grade, which reduces transparency for direct comparison.

Low confidence — this extraction should be reviewed alongside the original source.

Reasoning: The Total Island Gold District's Measured and Indicated gold resources saw a notable decrease in contained metal, tonnage, and grade, primarily due to conversion to reserves.

- Negative factor: Total Island Gold District Measured and Indicated resources decreased by 19% to 2.029 million ounces.

- Negative factor: The contained metal decreased by 19% from 2.506 million ounces to 2.029 million ounces.

- Negative factor: The tonnage decreased by 9% from 64.823 million tonnes to 58.891 million tonnes.

- Negative factor: The grade decreased by 11% from 1.20 g/t Au to 1.07 g/t Au.

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: qp\_signed is true

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: reporting\_standards includes ni\_43\_101

**Tonnage Decline**

Polarity: negative

Definition: Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down.

Why it applies: 58891000 against 64823000 previously

**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: 1.07 against 1.2 previously

**Contained Metal Decline**

Polarity: negative

Definition: Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.

Why it applies: 2029000 against 2506000 previously

## 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.
