## Minestarters Atlas summary

Fortuna Mining Corp. has updated the Diamba Sud Gold Project Mineral Resource estimate, expanding Indicated resources by 73% to 1.25 million ounces. The update is driven by infill and expansion drilling, with 94% of the total gold ounces now classified as Indicated.

Reasoning: The update shows substantial growth in Indicated gold ounces and a high confidence category mix, advancing the project toward a feasibility study.

- Positive factor: Significant tonnage and ounce growth \(73% increase in Indicated\)

- Positive factor: High proportion of Indicated resource \(94%\)

- Positive factor: First-time Indicated resource at Southern Arc

- Positive factor: Infill drilling successfully upgraded categories

- Negative factor: Resource is still in the Inferred category for some zones

Facts used in scoring: 30

## Classification and evidence

**Category Upgrade**

Polarity: positive

Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.

Why it applies: Infill drilling successfully upgraded Inferred to Indicated Mineral Resource category at several deposits.

Evidence · text

> Infill drilling successfully upgraded Inferred to Indicated Mineral Resource category

**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: Eric Chapman, P. Geo., is the Qualified Person responsible for the Mineral Resources.

Evidence · text

> Eric Chapman, P. Geo. \(EGBC \#36328\), is the Qualified Person responsible for Mineral Resources

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: Mineral Resources are reported using the 2014 CIM Definition Standards and NI 43-101.

Evidence · text

> Mineral Resources are reported using the 2014 CIM Definition Standards.

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The release discloses specific cut-off grades for oxide/transitional and fresh material across different deposits.

Evidence · text

> incremental gold cutoff grade for oxide/transitional material of 0.26 g/t Au

## 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.
