## Minestarters Atlas summary

GRSilver has reported high-grade silver drill results from its San Marcial project, specifically from hole SMS26-03. The results include a significant 15.6m intercept at 351 g/t Ag, confirming mineralization continuity up to 500m down dip.

Reasoning: The announcement reports an exceptional silver intercept \(351 g/t over 15.6m\) and a bonanza-grade sub-interval \(1,395 g/t\), confirming mineralization continuity at depth.

- Positive factor: exceptional silver grades

- Positive factor: significant intercept width

- Positive factor: high-grade sub-interval

- Positive factor: demonstrated continuity

Facts used in scoring: 2

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The 2.5m intercept at 1,395 g/t Ag is exceptionally high-grade for silver.

Evidence · text

> 2.5 m at 1,395 g/t Ag

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results are part of a 20,000 m step-out drilling campaign.

Evidence · text

> 20,000 m Step-Out Drilling Campaign

## 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.
