## Minestarters Atlas summary

Madoro Metals has discovered a new polymetallic skarn-hornfels mineralization zone at the western margin of the Yautepec caldera. Preliminary rock chip sampling yielded high-grade values including up to 1.2 kg/t Ag and 3.97 wt% Cu.

Reasoning: Discovery of a new polymetallic skarn zone with high-grade silver and copper rock chip samples, extending the known mineralized footprint of the Yautepec project.

- Positive factor: newly discovered skarn mineralization

- Positive factor: high grade silver and copper in rock chips

- Positive factor: large scale potential \(1km outcrop\)

- Positive factor: structural continuity across caldera

Facts used in scoring: 2

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Discovery of a new skarn-hornfels mineralization area west of the previously mapped southern margin.

Evidence · text

> new area of skarn-hornfels alteration and mineralization was identified

**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: Release mentions ALS Labs and a Qualified Person \(Robert Johansing\) review.

Evidence · text

> Rock Chip Sampling Results \(n = 20 -- ALS Labs\)

## 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.
