## Minestarters Atlas summary

East Africa Metals has released an updated mineral resource estimate for the Magambazi project in Tanzania, significantly upgrading the resource to the Measured and Indicated category. The update shows a 34% increase in grade and a 35% increase in contained gold ounces compared to the 2012 estimate, supported by an expanded dataset of 468 drill holes.

Reasoning: The update represents a significant de-risking event for the Magambazi project, converting a large portion of inferred resources to M&I and showing material growth in both grade and contained metal.

- Positive factor: Significant upgrade of resource category from Inferred to Measured and Indicated

- Positive factor: Substantial growth in contained gold ounces \(35% improvement\)

- Positive factor: Substantial growth in grade \(34% improvement\)

- Positive factor: Expanded dataset with 468 drill holes vs 400 previously

- Positive factor: JORC compliant update

Facts used in scoring: 7

## 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: The bulk of the inferred resource in 2012 has been upgraded to the measured and indicated category.

Evidence · text

> The bulk of the inferred resource in 2012 mineral resource estimate has been upgraded to the measured and indicated category

**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: Contained gold ounces improved by 35% over the 2012 calculation.

Evidence · text

> representing a 34% improvement on grade and a 35% improvement of ounces over the 2012 calculation

**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: Andrew Lee Smith, P.Geo., has reviewed and approved the technical contents.

Evidence · text

> Andrew Lee Smith , P.Geo., C.E.O., a Qualified Person under the definitions of National Instrument 43-101, has reviewed and approved the technical contents of this press release.

**JORC Compliant**

Polarity: positive

## 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.
