## Minestarters Atlas summary

Coppernico Metals announced significant channel sampling results from Zone 1 at its Sombrero Project's Nioc target, defining a continuous surface footprint of copper mineralization measuring approximately 170m by 200m. Highlights include 155m averaging 0.54% Cu, 164m averaging 0.41% Cu, and a high-grade intercept of 12m at 2.82% Cu. The company noted that mineralization remains open to the north and south, coincident with a large chargeability anomaly, reinforcing the potential for a large copper skarn system.

Reasoning: Coppernico announced significant channel sampling results at its Nioc target, defining broad and continuous copper mineralization with high-grade zones. The results expand the known surface footprint and indicate a large-scale skarn system, with mineralization remaining open and coincident with geophysical anomalies, suggesting potential at depth. While positive, the results are from shallow surface samples, and true thickness is unknown.

- Positive factor: Broad, continuous copper mineralization defined over significant widths \(up to 164m\)

- Positive factor: High-grade copper intercepts \(up to 2.82% Cu over 12m\) within broader mineralized envelope

- Positive factor: Surface footprint expanded to 170m x 200m, reinforcing scale potential of the skarn system

- Positive factor: Mineralization remains open to the north and south, coincident with a large chargeability anomaly

- Positive factor: QA/QC procedures disclosed and Qualified Person sign-off

- Negative factor: Results are from surface channel sampling, not drilling, with maximum depth of 1.5m

- Negative factor: True thickness of mineralization is unknown

- Negative factor: Some internal dilution included in reported composites

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 25

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Channel 068 returned 12.0m at 2.82% Cu, which is above the 2.5% exceptional threshold for copper in skarn deposits.

Evidence · table

> 2.82

Context: 12.0

**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 'True thickness is unknown' for the channel sampling results.

Evidence · text

> True thickness is unknown

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results 'significantly expand the known extent of surface mineralization' and 'extended mineralization laterally and along strike'.

Evidence · text

> These results significantly expand the known extent of surface mineralization

**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 a Qualified Person \(Tim Kingsley\), ALS Laboratories, and QA/QC programs including blanks, standards, and duplicates.

Evidence · text

> The scientific and technical information contained in this news release was reviewed and approved by Tim Kingsley, M.Sc., CPG, Coppernico’s Vice President of Exploration, who is a “Qualified Person” as defined in NI 43-101. ... Samples were collected in plastic bags, given a unique reference number and sent to the ALS Laboratories in Lima, Peru for preparation and analysis. ... QA/QC programs for 2025 channel samples included internal standard samples, blanks, and duplicates, lab duplicates, lab standards, and laboratory blanks indicate good overall accuracy and precision.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The document states the internal dilution rules \('No more than 6 consecutive meters of internal dilution \(defined as reported values below 0.2% Cu\)'\) and minimum reporting length.

Evidence · text

> No more than 6 consecutive meters of internal dilution \(defined as reported values below 0.2% Cu\). Minimum reporting length of 6 m.

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: cutoff\_grade and internal dilution are both stated

## 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.
