## Minestarters Atlas summary

Masivo Silver reported encouraging results from its first drill hole \(CC-26-001\) at the Cerro Colorado Project in Sonora, Mexico. The hole intersected a broad 32.5m polymetallic zone with silver, zinc, lead, copper, and gold, showing strengthening grades near the bottom before being terminated for technical reasons.

Reasoning: First hole of the 2026 program shows encouraging broad polymetallic intercepts with grades increasing toward the bottom of the hole, though the hole was terminated prematurely.

- Positive factor: broad mineralization width

- Positive factor: strengthening grades at depth

- Positive factor: persistent polymetallic signature

- Positive factor: strong alteration

- Negative factor: hole terminated early due to technical difficulties

- Negative factor: true width not yet determined

Facts used in scoring: 20

## 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 the technical review and approval by a Qualified Person \(Brian Brewer\).

Evidence · text

> reviewed and approved by Brian Brewer, a Qualified Person

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that true widths have not yet been determined.

Evidence · text

> True widths have not yet been determined.

## 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.
