## Minestarters Atlas summary

Edge Copper reported assay results from eight additional diamond drill holes at its Zonia Copper Project in Arizona, confirming broad, near-surface oxide copper mineralization. Key intercepts include 475 ft at 0.25% CuT and 277 ft at 0.33% CuT, both from surface. Crucially, the drilling has demonstrated that mineralization extends beyond previously interpreted western and eastern geological boundaries, indicating a larger scale potential for the deposit which will be incorporated into an updated geological model and a Q4 2026 Mineral Resource estimate.

Reasoning: The drill results confirm broad, near-surface oxide copper mineralization and, more importantly, demonstrate that mineralization extends beyond previously interpreted geological boundaries, suggesting a larger scale potential for the Zonia project. This significantly de-risks the project and provides strong upside for the upcoming Mineral Resource estimate.

- Positive factor: Broad, near-surface oxide copper intercepts, including 475 ft grading 0.25% CuT and 277 ft grading 0.33% CuT from surface.

- Positive factor: Drilling demonstrates mineralization extends beyond previously interpreted geological boundaries \(western lithologic contact and eastern fault\), significantly increasing the potential scale of the deposit.

- Positive factor: Results will be incorporated into an updated geological model and a planned Q4 2026 Mineral Resource estimate.

- Positive factor: Drill orientations were selected to be broadly orthogonal to the interpreted strike and dip, and reported intervals are interpreted to represent approximate true thicknesses.

- Positive factor: Comprehensive QA/QC procedures were followed, including certified reference materials, blanks, and duplicates, with assays performed by an independent, accredited laboratory \(Skyline Assayers and Laboratories\) and approved by a Qualified Person.

- Negative factor: The reported 'approximate true thicknesses' imply some estimation rather than precise measurement.

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

Facts used in scoring: 14

## Classification and evidence

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states: 'Based on the current geological interpretation and drill geometry, the reported intervals are interpreted to represent approximate true thicknesses.'

Evidence · text

> Current drilling demonstrates that mineralization crosses both features, and neither is now considered a hard boundary.

**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 includes a detailed QA/QC section mentioning industry-standard procedures, certified reference materials, blanks, duplicates, and an independent, accredited laboratory.

## 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.
