## Minestarters Atlas summary

Zacatecas Silver reported high-grade gold and silver results from surface rock-chip sampling at the Oso Negro project in Sonora, Mexico. The sampling identified mineralization over a 2 km strike length, with intercepts up to 14.8 g/t Au and 2,340 g/t Ag, suggesting significant potential at depth.

Reasoning: Strong high-grade surface results across a significant strike length in a prospective epithermal system, providing a compelling drill target.

- Positive factor: High-grade surface intercepts \(14.8 g/t Au, 2,340 g/t Ag\)

- Positive factor: System-scale continuity over 2 km strike length

- Positive factor: Geological context suggests higher grades at depth \(above boiling zone\)

- Positive factor: QA/QC protocols disclosed \(ALS, blanks, standards, duplicates\)

- Negative factor: Surface sampling only \(rock-chip/grab\), no drill intercepts yet

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: 14.8 g/t Au and 2,340 g/t Ag are exceptionally high grades for an epithermal system.

Evidence · text

> Up to 14.8 g/t Au and 2,340 g/t Ag returned from surface rock-chip sampling

**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 ALS laboratory, certified reference materials, blanks, and field duplicates.

Evidence · text

> The Company inserted certified reference materials, blanks and field duplicates into the sample stream

## 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.
