## Minestarters Atlas summary

Amarillo Gold has announced a new resource model for the Posse deposit at the Mara Rosa Project in Brazil. The update shows a 53% increase in Measured gold resources and an 84% increase in Inferred resources compared to the 2011 estimate.

Reasoning: Significant growth in Measured and Inferred categories driven by new drilling and improved modeling, increasing project scale and confidence.

- Positive factor: Measured resource increased by 53%

- Positive factor: Inferred resource increased 84%

- Positive factor: Improved geological confidence with higher M&amp;I proportion

- Positive factor: Deposit remains open to depth and along strike

- Positive factor: QP sign-off provided

Facts used in scoring: 6

## 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 proportion of M+I category that moved to Measured increased 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: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

Why it applies: Inferred resource tonnage increased by 84% over the 2011 estimate.

Evidence · text

> Inferred resource has increased 84% over the 2011 estimate.

**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 AusIMM is named as the independent QP.

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 0.5 g/t cutoff is explicitly stated for the new estimate.

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.
