## Minestarters Atlas summary

GRSilver has reported high-grade silver drill results at the San Marcial Area of the Plomosas Project in Mexico. The results confirm the extension of silver mineralization for at least 150 metres southeast of the 2023 Mineral Resource Estimate boundary.

Reasoning: The drill results report an exceptional silver grade \(447 g/t\) and confirm a significant step-out extension of the mineralized zone beyond the previous MRE boundary.

- Positive factor: high-grade silver intercept

- Positive factor: step-out extension of mineralization

- Positive factor: significant width

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 6.15 m intercept at 447 g/t Ag is exceptionally high-grade for silver.

Evidence · text

> 6.15 m at 447 g/t Ag

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling confirms extension of mineralization 150m southeast of the 2023 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

## 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.
