## Minestarters Atlas summary

GR Silver reported high-grade silver results from its 2026 step-out drilling campaign at the San Marcial project, including a 15.6 m intercept at 351 g/t Ag in hole SMS26-03. The results confirm the continuity of the silver-mineralized system at depth in the SE Area and open up new potential in the upper volcanic sequence.

Reasoning: Significant high-grade silver intercepts in a step-out campaign that extend known mineralization and open new targets.

- Positive factor: High-grade silver intercepts \(up to 1,395 g/t Ag\)

- Positive factor: Step-out drilling confirms continuity of mineralization at depth

- Positive factor: Opens new exploration potential in previously interpreted barren zones

- Positive factor: Strong geological/structural model support

- Negative factor: True width not estimated due to insufficient data

Facts used in scoring: 30

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: 1,395 g/t Ag is exceptionally high for an epithermal system.

Evidence · table

> 1,395

Context: 2.5

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling in the SE Area confirms continuity and expands the known mineralized footprint.

Evidence · text

> confirm the continuity of high-grade silver mineralization up to 500 metres down dip from surface

**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 details QA/QC procedures including blanks, duplicates, and standards at SGS de México.

Evidence · text

> insertion of blank, duplicate, and standard samples

**Apparent Width Only**

Polarity: negative

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

Why it applies: The document explicitly states that true width was not estimated due to insufficient data.

Evidence · text

> True width not estimated as there is insufficient data

## 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.
