## Minestarters Atlas summary

GR Silver has reported significant step-out drill results at the San Marcial Area of the Plomosas Project in Mexico. The drilling confirmed high-grade silver mineralization extending at least 150 metres southeast of the existing resource boundary and identified new mineralized structures in the Parallel Breccia target.

Reasoning: The results confirm a significant lateral extension of the high-grade silver system and identify new prospective targets, validating the exploration model.

- Positive factor: Step-out drilling confirms extension of high-grade silver mineralization

- Positive factor: Significant true width intercepts reported in SE Extension

- Positive factor: Discovery of new mineralized structures in Parallel Breccia target

- Positive factor: QA/QC protocols and QP sign-off disclosed

Facts used in scoring: 46

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling confirms extension of high-grade silver mineralization for at least 150m southeast of the MRE boundary.

Evidence · text

> confirms the extension of high-grade silver mineralization for least an additional 150 metres to the southeast of the 2023 NI 43-101 Mineral Resource Estimate \("MRE"\) boundary.

**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 insertion of blanks, duplicates, and standards in all sample lots.

Evidence · text

> The Company has implemented QA/QC procedures, which include the insertion of blank, duplicate, and standard samples

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: Multiple intercepts report true width \(TW\) explicitly.

Evidence · text

> 21.9 m true width \("TW"\) at 168 g/t Ag

Reasoning: Expanded from assay table. 0.5 % zinc is below against the default band \[18, 10, 5, 2\] %. Grade×width 0.9 %·m is below.

- Negative factor: 0.5 % zinc is below the weak threshold \(2 %\) on the default band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

#### Tags used in scoring

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: true\_width\_m is 1.7

**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

Reasoning: Expanded from assay table. 8 g/t silver is below against the default band \[500, 200, 100, 30\] g/t. Grade×width 6.0 g/t·m is below.

- Negative factor: 8 g/t silver is below the weak threshold \(30 g/t\) on the default band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

## 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.
