## Minestarters Atlas summary

Altamira Gold reported high-grade gold intercepts at the new Guillermo target, including 0.9m @ 18.1 g/t Au. Additionally, drilling at the Maria Bonita resource confirmed mineralization continues at depth, extending the known system.

Reasoning: The announcement reports significant high-grade gold intercepts at a new target \(Guillermo\) and confirms depth continuity at an existing resource \(Maria Bonita\), demonstrating district-scale potential.

- Positive factor: High-grade gold intercept at new Guillermo target

- Positive factor: Extension of Maria Bonita mineralization at depth

- Positive factor: Multiple exploration targets showing positive results

- Negative factor: True width of Guillermo intercept not yet known

Facts used in scoring: 6

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drill hole MBA-034 extended known mineralization more than 100m below previously tested depth.

Evidence · text

> Drill hole MBA-034 extended the known gold mineralization more than 100 metres below the previously tested depth

- Event date: 2026-03-18T00:00:00.000Z

Reasoning: 4.2 g/t over 7m is a strong exploration intercept.

- Positive factor: Strong grade for exploration target

- Negative factor: Apparent width only

Evidence · text

> 7 metres @ 4.2g/t gold from 111m in drill hole GLO-01

#### Rejected tags

**Apparent Width Only** — Rejected; excluded from scoring

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Reason: The true width of the mineralized interval in the drill hole is not currently known.

Evidence · text

> the true width of the mineralized interval in the drill hole is not currently known

**QA/QC Disclosed** — Rejected; excluded from scoring

Polarity: positive

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

Reason: Release mentions SGS Geosol, fire assay, and use of blanks, standards, and duplicates.

Evidence · text

> For all drilling, half core is submitted to SGS Geosol... inserting control samples randomly into the submitted batch, comprising field duplicates, independent reference samples and 'blank' samples.

## 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.
