## Minestarters Atlas summary

Nord Precious Metals has reported high-grade silver drill results from the Castle East project, including a bonanza intercept of 61,389 g/t Ag over 0.30m in hole CS-21-73W1. The results represent a direct extension of the Robinson high-grade silver vein system and include significant cobalt and nickel mineralization.

Reasoning: Exceptional silver grades and significant step-out extension of the high-grade Robinson zone, supported by clear QA/QC and true width disclosures.

- Positive factor: Bonanza silver intercept \(61,389 g/t\)

- Positive factor: Step-out extension of Robinson vein system

- Positive factor: True width disclosed for high-grade vein

- Positive factor: QA/QC disclosed with lab and QP details

Facts used in scoring: 16

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: 61,389 g/t Ag is exceptionally high grade.

Evidence · text

> 61,389 g/t \(1,790.8 oz/ton\) Silver

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document explicitly states the true width of the high-grade vein is 7 cm and 2.5 cm.

Evidence · text

> Vein intercepted at 501.9m is 7 cm true width.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The intersection is described as a direct extension of the Robinson high-grade silver vein system.

Evidence · text

> is a direct extension of the Robinson high-grade silver vein system

**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: The release details the insertion of blanks, standards, and duplicates by Swastika Laboratories Ltd.

Evidence · text

> includes the insertion of one blank and one standard every 20 samples, in addition to the regular insertion of blanks, duplicates, and standards

## 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.
