## Minestarters Atlas summary

Minaurum has successfully rehabilitated access to the historic Promontorio mine, including the 55m-deep Balvanera shaft. Preliminary underground channel sampling has returned high-grade silver-equivalent intercepts, including 0.30 m at 4,142 g/t AgEq.

Reasoning: High-grade silver channel samples \(up to 4,142 g/t AgEq\) and successful access to historic mine workings provide significant exploration upside.

- Positive factor: High-grade silver intercepts from channel sampling

- Positive factor: Successful underground rehabilitation providing access to new areas

- Positive factor: QA/QC protocols and certified lab \(ALS\) disclosed

- Negative factor: Channel sampling is less representative than diamond drilling

Facts used in scoring: 20

## Classification and evidence

**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 includes detailed QA/QC protocols, including standards, blanks, and duplicates, with ALS Minerals as the laboratory.

Evidence · text

> Preparation and assaying of drilling samples from Minaurum's Alamos project are done with strict adherence to a Quality Assurance/Quality Control \(QA/QC\) protocol.

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The 0.30 m intercept at 4,142 g/t AgEq is exceptionally high grade.

Evidence · text

> 0.30 m of 4,142 g/t silver equivalent \(“AgEq”\)

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

## 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.
