## Minestarters Atlas summary

Edge Copper announced assay results from eight additional diamond drill holes at its Zonia Copper Project in Arizona, bringing the total reported holes to 45. Highlights include ZND0030 with 140 ft grading 0.45% CuT from surface and 340 ft grading 0.30% CuT at depth, extending mineralization vertically. Hole ZND0060 extended mineralization beyond the current PEA design pit, reinforcing the continuity and scale of the copper system and informing future resource model updates.

Reasoning: Edge Copper reported encouraging drill results from its Zonia Copper Project, featuring multiple wide intercepts of oxide copper, with some grades exceeding the project average and extending the known mineralization both at depth and laterally, which will support an upcoming Mineral Resource estimate update.

- Positive factor: Multiple broad intercepts of oxide copper mineralization

- Positive factor: Highest grade of 0.63% CuT is above the project average and 75th percentile for porphyry copper

- Positive factor: ZND0030 extends mineralization to depth \(550 ft vertical extent\)

- Positive factor: ZND0060 extends mineralization laterally beyond the current PEA design pit

- Positive factor: Results will inform an updated Mineral Resource estimate

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

- Positive factor: Approximate true thicknesses are reported

- Negative factor: No bonanza grades reported

- Negative factor: Some intercepts are below the project's historical average grade

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

Reasoning: Hole ZND0039 delivered an exceptionally wide near-surface intercept, significantly contributing to the overall resource volume in the northern area.

- Positive factor: Exceptional intercept width \(189.9 m\) from near surface

- Positive factor: Grade of 0.23% CuT is above the 25th percentile for porphyry copper

- Positive factor: Located in the northern part of the deposit

- Negative factor: Grade is below the project average \(0.306% Cu\)

## 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.
