## Minestarters Atlas summary

Edge Copper has reported assay results from eight diamond drill holes at its Zonia Copper Project in Arizona, highlighting broad intervals of oxide copper mineralization. Key intercepts include 42.67m at 0.45% total copper from surface in ZND0030, and 75.59m at 0.30% total copper in ZND0060, which extended mineralization beyond the current PEA design pit. These results will be incorporated into an updated geological and Mineral Resource model, with an updated estimate targeted for Q4 2026.

Reasoning: The drill results show broad, continuous zones of oxide copper mineralization with moderate to strong grades, extending the known footprint and reinforcing continuity. The company has robust QA/QC and QP sign-off, and the results will inform an updated Mineral Resource estimate, indicating positive progress for the Zonia Copper Project.

- Positive factor: Broad intervals of moderate to strong grade oxide copper mineralization reported from multiple holes.

- Positive factor: Hole ZND0030 returned significant near-surface and deeper intercepts, reinforcing continuity.

- Positive factor: Hole ZND0060 extended mineralization beyond the current PEA design pit, indicating potential for resource expansion.

- Positive factor: Comprehensive QA/QC procedures are disclosed, including certified lab and QP sign-off.

- Positive factor: Drill holes are interpreted to represent approximate true thicknesses, suggesting good drill orientation.

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

Facts used in scoring: 16

## 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 explicitly states that drill samples were collected under industry-standard QA/QC procedures, including insertion of certified reference materials, blanks, and duplicate samples, and that Skyline Assayers and Laboratories is accredited and independent.

Evidence · text

> All drill samples were collected under the supervision of the Company's geological staff in accordance with industry-standard quality assurance and quality control \("QA/QC"\) procedures.

**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 that intervals are 'interpreted to represent approximate true thicknesses' rather than providing calculated true widths or specific drill orientation data to confirm true width.

Evidence · text

> Based on the current geological interpretation and drill geometry, intervals reported in this news release are interpreted to represent approximate true thicknesses.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Hole ZND0060 is reported to be on the northwestern margin of the deposit, beyond the current PEA design pit, indicating an extension of known mineralization.

Evidence · text

> ZND0060 returned 248 ft grading 0.30% CuT from 553 ft... The reported oxide and mixed mineralization is on the northwestern margin of the deposit, beyond the current PEA design pit

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: Hole ZND0030 adds broad copper intervals in the central part of the deposit beneath several shallow historical holes, and the overall program aims to inform updates to Mineral Resource models.

Evidence · text

> ZND0030, drilled in the central part of the deposit beneath several shallow historical holes. It returned 140 ft grading 0.45% total copper \(CuT\) from 0 ft

**Cut-off Disclosed**

Polarity: positive

Story-specific tag

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: Significant intervals were calculated using a 0.10% CuT cut-off, which is explicitly stated in the notes for the significant intercept table.

Evidence · text

> Significant intervals reported in this news release were calculated using a 0.10% CuT cut-off.

## 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.
