## Minestarters Atlas summary

NevGold Corp. has reported striking gold-equivalent drill intercepts at its Limousine Butte project in Nevada, featuring significant antimony content. Additionally, Phase II metallurgical testwork confirmed high gold recoveries \(up to 99%\) following antimony leaching, supporting a sequential processing flowsheet.

Reasoning: The document reports significant high-grade drill intercepts for a critical mineral \(antimony\) and strong metallurgical results that de-risk the sequential recovery of gold and antimony.

- Positive factor: High-grade antimony-gold intercepts

- Positive factor: Strong metallurgical gold recoveries after antimony leaching

- Positive factor: Strategic critical mineral \(antimony\) focus

- Positive factor: Near-surface oxide deposit amenable to direct leaching

- Negative factor: Metal equivalent assumptions not fully transparent in prose \(though prices/recoveries are stated\)

Facts used in scoring: 9

## Classification and evidence

**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 document mentions Phase II metallurgical testwork results and drill results, though specific lab names for the drill assays are not in this snippet, the metallurgical results are presented as formal results.

Evidence · text

> NevGold reported Phase II metallurgical testwork results

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The company reported significant oxide gold-antimony mineralization in all step-out drillholes at the Bullet Zone discovery.

Evidence · text

> significant oxide gold-antimony mineralization had been intercepted in all step-out drillholes at the Bullet Zone discovery

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the document describes a flotation route \("concentrate"\)

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

## 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.
