## Minestarters Atlas summary

Astra Exploration has defined a large high-sulphidation epithermal gold target at the Don Mario project in Chile using geochemical, spectral, and geophysical surveys. The results identify a 2km x 1km gold-silver anomaly and significant resistive anomalies, with a 2,000-3,000 metre drill program planned for Q1 2027.

Reasoning: The release announces the definition of a drill-ready target through mapping, geochemistry, and geophysics, but does not contain new drill assay results.

- Positive factor: Identification of a large 2km x 1km gold-silver geochemical target

- Positive factor: Geophysical survey identifies two significant resistive anomalies \(shallow and deep\)

- Positive factor: Surface rock-chip anomalies up to 1.35 g/t gold

- Positive factor: Planned 2,000-3,000m drill program to test targets

- Negative factor: No new drill assays reported in this release

- Negative factor: Historical drill results mentioned are unverified

Facts used in scoring: 4

## Classification and evidence

**Nearology Play**

Polarity: neutral

Story-specific tag

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: The project is located in the Maricunga gold belt, near the Refugio Mine.

Evidence · text

> located in the Maricunga belt approximately 20 kilometres from the Refugio Mine.

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: The release details the insertion of 14 QAQC samples including duplicates, standards, and blanks.

Evidence · text

> a systematic protocol was implemented that included the insertion of 14 QAQC samples, including duplicate samples, standards, and blanks.

Evidence · text

> Eight shallow RC holes were completed by previous operators and returned 20 metres and 32 metres of 0.41 g/t gold and 0.38 g/t gold respectively

#### Tags used in scoring

**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: qaqc\_disclosed is true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: the fact restates a prior release

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "\*\*The 100% owned Don Mario \(renamed from Cerro Bayo\) project in northern Chile\*\*is located in the Maricunga belt approxi"

## 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.
