## Minestarters Atlas summary

Amarillo Gold has announced a new resource model for the Posse deposit at the Mara Rosa Project in Brazil, significantly increasing the Measured resource by 53% and the Inferred resource by 84% compared to the 2011 estimate. The update, based on 34 new drill holes and improved geophysical data, provides a more robust foundation for updating the project's Pre-Feasibility Study.

Reasoning: Significant growth in Measured and Inferred resource categories driven by new drilling and improved modeling, increasing the overall scale and confidence of the Posse deposit.

- Positive factor: Measured resource increased by 53%

- Positive factor: Inferred resource increased by 84%

- Positive factor: Improved geological confidence via category migration \(Inferred to M&I\)

- Positive factor: QP sign-off provided

- Positive factor: Cut-off grade disclosed

Facts used in scoring: 6

## Classification and evidence

**Measured Resource**

Polarity: positive

Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves.

Why it applies: The report identifies a significant Measured resource component of 8.568Mt @ 2.00 g/t Au.

Evidence · text

> Measured resource has increased by over 50%

**Category Upgrade**

Polarity: positive

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

Why it applies: The proportion of M+I category that moved to Measured increased, improving confidence.

Evidence · text

> The proportion of the \(M+I\) category which has moved to a Measured resource increases confidence in the model.

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: Measured resource tonnage increased by 53% and Inferred by 84% vs 2011 estimate.

Evidence · text

> increases Measured Resource by 53% @ 2.00 g/t Au

**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: Keith Whitehouse of AEFS is named as the independent Qualified Person.

Evidence · text

> Keith Whitehouse is the independent Qualified Person \(QP\) for this resource statement

**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 resource was calculated at a 0.5 g/t cutoff.

Evidence · text

> calculated the new resource estimate at a 0.5 g/t cutoff

## 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.
