## Minestarters Atlas summary

Edge Copper announced assay results from nine additional diamond drill holes at its Zonia Copper Project in Arizona, primarily focused on infill drilling within the current mineral resource area. The results, including broad intervals of oxide copper mineralization, reinforce continuity and support increasing confidence in the resource model. The company is now transitioning to systematic deposit-extent drilling to define the limits of the mineralized system and plans an updated Mineral Resource estimate in Q4 2026.

Reasoning: Edge Copper reported broad infill and deposit-extent copper intercepts at its Zonia project, reinforcing continuity and supporting future resource upgrades. While individual grades are moderate to strong for a porphyry open pit, the grade-thickness products are mostly weak. The shift to deposit-extent drilling is a positive step for defining the full mineralization footprint.

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

Facts used in scoring: 18

## Classification and evidence

**Infill Drilling**

Polarity: neutral

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

Why it applies: The reported holes were drilled primarily as infill within the current mineral resource area to increase confidence in the resource model.

Evidence · text

> The holes reported today were drilled primarily as infill within the current mineral resource area and returned broad intervals of copper mineralization that reinforce continuity of the oxide system and support the Company's objective of increasing confidence in the current resource model.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The company is shifting the balance of drilling toward systematic testing of the deposit extents and around the perimeter of the mineralized system.

Evidence · text

> As the infill program advances, Edge Copper is shifting the balance of drilling toward systematic testing of the deposit extents. Current and planned holes are progressing around the perimeter of the mineralized system to establish hanging-wall and footwall contacts from surface to depth and to test continuity along strike, up dip and down dip.

**True Width Disclosed**

Polarity: positive

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

Why it applies: The news release explicitly states that reported intervals are interpreted to represent approximate true thicknesses based on geological interpretation and drill geometry.

Evidence · text

> Based on the current geological interpretation and drill geometry, 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 document includes a detailed QA/QC section mentioning industry-standard procedures, certified reference materials, blanks, duplicates, and laboratory reviews.

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. Samples are from HQ-diameter core. Core is scanned and logged by the Company's geology team before being cut. Half-core HQ samples are prepared for assay and the remaining material is retained at site for future reference. 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.

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: The scientific and technical information has been approved by Patrick B. Redmond, Ph.D., P.Geo., a Qualified Person as defined by NI 43-101.

Evidence · text

> The scientific and technical information contained in this news release has been approved by Patrick B. Redmond, Ph.D., P.Geo., a consultant to the Company, who is a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

**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 clearly stated 0.10% CuT cut-off.

Evidence · text

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

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The drilling aims to increase confidence in the current resource model and support an updated Mineral Resource estimate in Q4 2026.

Evidence · text

> The results support the objective of increasing confidence in the current resource and evaluating future conversion of Inferred Mineral Resources to the Indicated category.

## 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.
