## Minestarters Atlas summary

Coppernico Metals has reported new surface channel sampling results at the Nioc target of its Sombrero Project in Peru. The results include a 70.1 m intercept of 0.92% Cu and 0.25 g/t Au, effectively doubling the known east-west width of mineralization at Zone 2 and demonstrating northward step-out extension.

Reasoning: The results demonstrate a significant northward expansion and doubling of the known surface width of mineralization at the Nioc target, although these are surface channel samples and true width is not stated.

- Positive factor: Step-Out Extension

- Positive factor: continuous high-grade skarn mineralization

- Positive factor: doubling of surface width

- Negative factor: Apparent Width Only

Facts used in scoring: 19

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Channel 26SRT-111 is located 120m north of the combined line, demonstrating northward expansion.

Evidence · text

> demonstrating a meaningful northward expansion of the Zone 2 footprint

**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 details QA/QC protocols including standards, blanks, and duplicates.

Evidence · text

> QA/QC programs for 2025-2026 channel samples included internal standard samples, blanks, and duplicates

**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: Table notes explicitly state that true thickness is unknown.

Evidence · text

> True thickness is unknown

## 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.
