## Minestarters Atlas summary

Centerra Gold announced a significant increase in its 2025 year-end gold and copper mineral reserves, up 58% and 49% respectively, driven by updated estimates at Mount Milligan, Goldfield, and Kemess. The company also reported extensive exploration results, including high-grade gold and copper intercepts from Mount Milligan and Kemess, which are expanding existing resource shells and identifying new mineralization zones. While overall contained metal grew substantially, some grade dilution was noted across various resource categories.

Reasoning: Centerra Gold announced a substantial increase in its gold and copper mineral reserves and resources, driven by successful exploration and updated estimates at key projects like Mount Milligan, Goldfield, and Kemess. While overall contained metal increased significantly, some grade dilution was observed in certain categories. The document also provides extensive drill results from ongoing exploration programs, highlighting high-grade intercepts that contribute to resource expansion.

Reasoning: This intercept shows strong copper mineralization over a significant width, contributing to the expansion of the Mount Milligan resource.

- Positive factor: Strong copper grade \(0.475%\) for a porphyry deposit

- Positive factor: Significant intercept length \(23.0m\)

- Positive factor: Extends resource shell towards North Slope

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling at Goldmark resulted in the extension of the resource shell towards the North Slope area.

Evidence · text

> Drilling of the South Boundary area identified high-grade gold, low copper vein mineralization supporting a previous interpretation that the zone represents a gold rich cap of an underlying porphyry deposit, similar to the geometry of the 66 zone and the MBX stock. Continued drilling within the area has the potential to identify a gold-copper mineralization northwest towards the Boundary zone area.

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

**Tonnage Growth**

Polarity: positive

Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

Why it applies: 37034000 against 30833000 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: 0.67 against 0.71 previously

**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: 794 against 706 previously

Reasoning: Goldfield's Inferred gold resources show a decrease in contained gold, tonnage, and grade, indicating some re-evaluation or depletion in this category.

- Negative factor: Decrease in contained gold \(23 koz vs 30 koz prior\)

- Negative factor: Grade dilution \(0.33 g/t vs 0.41 g/t prior\)

- Negative factor: Decrease in tonnage \(2,121 kt vs 2,267 kt prior\)

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: category is "inferred"

**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: 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: 2121000 against 2267000 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: 0.33 against 0.41 previously

**Contained Metal Decline**

Polarity: negative

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

Why it applies: 23 against 30 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.
