## Minestarters Atlas summary

Edge Copper Corporation reported strong assay results from its Zonia Copper Project in Arizona, including a significant intercept of 287 ft at 0.73% Total Copper, with a higher-grade section of 190 ft at 1.01% Total Copper, in hole ZND0032. These results confirm and extend oxide copper mineralization, particularly in areas previously defined by shallow historical drilling, and will be incorporated into updated geological and resource models. The company also disclosed its QA/QC procedures and QP sign-off for the technical information.

Reasoning: The announcement reports strong drill results from the Zonia Copper Project, highlighted by a significant high-grade copper intercept in hole ZND0032. The results confirm and extend oxide copper mineralization, providing valuable inputs for geological and resource models. The disclosure of QA/QC procedures and QP sign-off adds to the confidence in the reported data.

- Positive factor: High-grade copper intercepts, particularly in ZND0032, exceeding typical porphyry open-pit thresholds.

- Positive factor: Significant widths of mineralization, including broad intervals.

- Positive factor: Confirmation of high-grade oxide copper mineralization in an area previously defined by shallow historical drilling, extending the known mineralization.

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

- Positive factor: True width is interpreted to be approximate true thickness, providing better geological context.

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

Facts used in scoring: 27

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: Hole ZND0032 returned 190 ft grading 1.01% CuT, which is an exceptional grade for an open-pit porphyry copper deposit.

Evidence · text

> 190 ft grading 1.01% CuT

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document states that 'intervals reported in this news release are interpreted to represent approximate true thicknesses.'

Evidence · text

> intervals reported in this news release are interpreted to represent approximate true thicknesses.

**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 disclosure of QA/QC procedures, including certified reference materials, blanks, and duplicate samples, and mentions Skyline Assayers and Laboratories is accredited and independent.

Evidence · text

> The Company's QA/QC program includes the insertion of certified reference materials, blanks and duplicate samples at regular intervals within the sample stream. The Company also conducts ongoing reviews of laboratory QA/QC performance to ensure analytical reliability and accuracy. Assay samples were picked up directly from site by Skyline Assayers and Laboratories \("Skyline"\) and transported to Skyline's laboratory facility in Tucson, Arizona for preparation and analysis. Skyline is accredited and independent of the Company.

**Compositing Transparent**

Polarity: positive

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

Why it applies: Significant intervals were calculated using a 0.10% CuT cut-off, indicating clear compositing rules.

Evidence · text

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

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Hole ZND0058 extends oxide/mixed mineralization beyond the current PEA Design Pit on the northwestern margin of the deposit, and ZND0052 also extends oxide copper mineralization beyond the current PEA Design Pit.

Evidence · text

> ZND0058 returned 165 ft grading 0.46% CuT from 579 ft, including 104 ft grading 0.64% CuT , together with a separate interval of 136 ft grading 0.13% CuT from 777 ft – extending oxide/mixed mineralization beyond the current PEA Design Pit on the northwestern margin of the deposit

## 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.
