## Minestarters Atlas summary

Spartan Metals has reported high-grade silver assays from its Eagle Project in Nevada, including an intercept of 688 g/t Ag over 0.3m. The sample also contains copper, antimony, and arsenic.

Reasoning: High-grade silver intercept \(688 g/t\) with significant copper and antimony, though arsenic is noted as a deleterious element.

- Positive factor: High silver grade

- Positive factor: Presence of copper and antimony

- Negative factor: Presence of arsenic

Facts used in scoring: 4

## Classification and evidence

**Deleterious Elements Present**

Polarity: negative

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

Why it applies: Arsenic \(1,336 ppm\) is mentioned in the assay results.

Evidence · text

> 1,336 ppm arsenic \(As\)

## 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.
