## Minestarters Atlas summary

Copper Fox Metals has reported analytical results from historical diamond drilling at the Van Dyke ISCR project in Arizona. The results, specifically in hole OXY-42, extend the total soluble copper \(TSCu\) mineralized envelope and better define the boundary between transitional and sulphide domains.

Reasoning: The results extend the known TSCu envelope in hole OXY-42 and include strong sub-intervals, though the data is a re-analysis of historical drill core.

- Positive factor: extension of mineralized envelope

- Positive factor: high-grade sub-intervals

- Negative factor: historical data re-release

- Negative factor: apparent width only

Facts used in scoring: 10

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The 2026 sampling in OXY-42 extended the TSCu mineralization from 336.19m to 436.78m.

Evidence · text

> extended the TSCu mineralization from 336.19m to 436.78m

**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 use of certified reference standards, blanks, and an ISO/IEC 17025 accredited laboratory.

Evidence · text

> 18 certified reference standards and 9 blanks

**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 states 'True thickness and widths of mineralization are currently unknown' and all holes are vertical.

Evidence · text

> True thickness and widths of mineralization are currently unknown

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The results are from a 'previously reported historical diamond drill core sampling program'.

Evidence · text

> from the previously reported historical diamond drill core sampling program

## 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.
