## Minestarters Atlas summary

Altamira Gold has completed its first deep drill hole at the Maria Bonita target, intersecting over 500m of highly altered porphyritic rocks. Additionally, surface mapping and grab sampling at the Tavares Norte target indicate an extension of the sericite alteration zone and returned high-grade gold \(up to 27.5 g/t Au\) and copper values.

Reasoning: The completion of the first deep hole \(MBA032\) showing 500m of alteration and high-grade surface samples at Tavares Norte provide strong exploration momentum, though the actual gold grades for the deep hole are pending.

- Positive factor: significant alteration thickness in deep hole

- Positive factor: high-grade surface grab samples

- Positive factor: extension of known alteration zone

- Negative factor: assay results for primary deep hole are still pending

Facts used in scoring: 6

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The sericite alteration zone at Tavares Norte extends 1.5km further east than previously known.

Evidence · text

> suggests that the sericite alteration zone extends 1.5km further east than previously known

**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: The release mentions gold analysis via SGS method FAA505 and monitoring via certified references and blanks.

Evidence · text

> Gold analysis has been conducted by SGS method FAA505... Analytical quality is monitored by certified references and blanks.

## 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.
