## Minestarters Atlas summary

Black Mammoth Metals has identified significant chargeability anomalies via an IP survey at the Cottonwood target in Nevada, suggesting potential sulfide-hosted gold mineralization. The company also reported a high-grade gold sub-interval from hole CW-2B and has expanded its claim coverage.

Reasoning: The release reports new geophysical anomalies that suggest sulfide-rich gold targets and restates a high-grade sub-interval from a previous drilling campaign.

- Positive factor: high chargeability anomaly identified

- Positive factor: gold intercept in CW-2B

- Positive factor: prospective structural corridor identified

- Negative factor: deleterious elements \(arsenic, antimony, mercury\) noted in hydrothermal fluids

Facts used in scoring: 2

## 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 release mentions a Qualified Person \(Mark J. Abrams, CPG \#11451\) has reviewed and approved the technical content.

Evidence · text

> Mark J. Abrams, CPG \#11451, a Qualified Person... has reviewed and approved the technical content

**Deleterious Elements Present**

Polarity: negative

Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release.

Why it applies: Hydrothermal fluids are noted to be bearing arsenic, antimony and mercury.

Evidence · text

> strongly altered by gold, arsenic, antimony and mercury-bearing hydrothermal fluids

## 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.
