## Minestarters Atlas summary

Altamira Gold Corp. reported trenching results at the Cajueiro Central Project that extend gold mineralization approximately 200m beyond the current Mineral Resource limit. The program also collected oxide metallurgical samples for upcoming heap leach testwork.

Reasoning: Trenching results identified significant gold mineralization \(up to 9.5 g/t\) extending 200m beyond the current Mineral Resource boundary, providing a clear new drill target.

- Positive factor: Step-Out Extension

- Positive factor: QA/QC Disclosed

Facts used in scoring: 19

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Trench 61 shows a 17m @ 1.46g/t Au intercept approximately 200m beyond the limit of the current Mineral Resource.

Evidence · text

> The intercept of 17m @ 1.46g/t Au lies approximately 200 m along strike beyond the limit of the current Mineral Resource

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Trench TCBL-0058 returned 4m @ 9.50 g/t Au, which is exceptionally high grade.

Evidence · table

> 9.50 g/t Au

Context: 4m

**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 gold analysis conducted by SGS using FAA505 method and monitoring by 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.
