## Minestarters Atlas summary

Altamira Gold reported significant drill results from hole MBA032 at the Maria Bonita project, intersecting 395.5m at 0.4 g/t gold. This deep hole confirms the continuity of the quartz porphyry system below the existing mineral resource, suggesting a much larger mineralized system than previously estimated.

Reasoning: The first deep drill hole \(MBA032\) successfully intersected a very wide \(395.5m\) mineralized interval, demonstrating that the porphyry system extends significantly below the existing resource footprint.

- Positive factor: significant depth extension of mineralized porphyry

- Positive factor: remarkable continuity of mineralization

- Positive factor: expansion of known mineralized footprint

Facts used in scoring: 4

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: MBA032 is the first deep hole below the existing resource, extending the mineralized system at depth.

## 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.
