## Minestarters Atlas summary

Edge Copper Corporation reported strong assay results from ten diamond drill holes at its Zonia Copper Project in Arizona, highlighted by hole ZND0032 intersecting 287 feet at 0.73% total copper, including 190 feet at 1.01% total copper. These results significantly exceed the project's average grade and extend mineralization beyond the current PEA design pit. The company plans to integrate these new findings into an updated Mineral Resource estimate in Q4 2026.

Reasoning: The drill results are highly positive, featuring exceptional copper grades over significant widths, particularly in hole ZND0032, which represents the highest-grade interval to date. The program also successfully extended mineralization beyond the current pit design and confirmed high-grade zones, indicating strong potential for resource expansion and de-risking. Robust QA/QC and transparent reporting further bolster confidence in these material and novel results.

- Positive factor: Exceptional grade and width in ZND0032, significantly exceeding project average and 75th percentile for porphyry copper deposits.

- Positive factor: Extension of mineralization beyond current PEA design pit by ZND0058, indicating potential resource growth.

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

- Positive factor: Comprehensive QA/QC disclosure and QP sign-off, enhancing data credibility.

- Positive factor: Clear disclosure of cut-off grade for interval calculation, improving transparency.

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: The intercept in ZND0032 of 1.01% CuT over 57.91m is an exceptional grade for a porphyry copper deposit \(exceptional >= 0.8% Cu\) over a strong width.

Evidence · table

> 1.01

Context: 190

**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

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Hole ZND0058 'extending oxide/mixed mineralization beyond the current PEA Design Pit on the northwestern margin of the deposit'.

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

**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 details QA/QC procedures, including certified reference materials, blanks, duplicates, and the use of an accredited laboratory \(Skyline Assayers and Laboratories\).

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. \(...\) The Company's QA/QC program includes the insertion of certified reference materials, blanks and duplicate samples at regular intervals within the sample stream.

**Compositing Transparent**

Polarity: positive

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

Why it applies: The cut-off grade used for calculating significant intervals \(0.10% CuT\) is clearly stated.

Evidence · text

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

**Infill Drilling**

Polarity: neutral

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

Why it applies: Hole ZND0032 'confirms high-grade oxide copper mineralization in an area previously defined only by shallow historical drilling'.

Evidence · text

> Hole ZND0032 confirms high-grade oxide copper mineralization in an area previously defined only by shallow historical drilling

## 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.
