## Minestarters Atlas summary

Altamira Gold has reported significant scout drilling results from the Maria Bonita project in Brazil, intersecting a 70.6m gold interval at 0.5 g/t. This intercept demonstrates the extension of the mineralized porphyry system to the west of the existing mineral resource.

Reasoning: Scout drilling successfully intersected a wide, mineralized porphyry interval 100m west of the existing resource, demonstrating significant exploration potential and footprint extension.

- Positive factor: Step-Out Extension

- Positive factor: continuity of the porphyry complex to the west

- Positive factor: wide interval of porphyry mineralization

Facts used in scoring: 3

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The intercept lies 100m below and to the west of the previously estimated mineral resource.

Evidence · text

> This intercept lies 100m below and to the west of the previously estimated mineral resource

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: Release mentions SGS Geosol laboratory, use of blanks, standards, and duplicates.

Evidence · text

## 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.
