## Minestarters Atlas summary

CopperEx Resources Corp. has identified a second parallel gold trend, the Sorpresa Trend, adjacent to its existing ADLP Trend at the Exploradora Norte Project in Northern Chile. Surface trenching defined gold and arsenic anomalism over 4.9 kilometers, with a highlight intercept of 22.5 meters at 0.59 g/t gold. This new trend, which is oxidized and exposed at surface, significantly increases the Franja del Oro target's potential for a large bulk tonnage oxidized gold resource and will be tested in an upcoming drill campaign.

Reasoning: CopperEx has identified a significant new 4.9 km long parallel gold trend through surface trenching, with a best intercept of 22.5m at 0.59 g/t gold, indicating potential for a large bulk tonnage oxidized gold resource that will be drill-tested soon. While grades are modest, the scale and surface exposure are positive.

- Positive factor: Identification of a new 4.9 km parallel gold trend \(Sorpresa Trend\)

- Positive factor: Potential for a large bulk tonnage oxidized gold resource

- Positive factor: Oxidized mineralization exposed at surface

- Positive factor: Comprehensive QA/QC procedures disclosed

- Positive factor: Upcoming drill campaign planned for the new trend

- Negative factor: Grades from new trenching are relatively low \(peak 0.59 g/t Au\)

- Negative factor: Trenching provides surface data, less definitive than drilling

- Negative factor: True width of trench intercepts not stated

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

## Classification and evidence

**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 lab \(AAA CHILE Ltd. ISO/IEC 17025:2005\), QP sign-off \(Daniel MacNeil, PGeo\), and methods like blanks, standards, and duplicates.

Evidence · text

> All rock samples have been sent to AAA CHILE Ltd. \("AAA"\) in Santiago Chile, for preparation and analysis. AAA meets all requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015 for analytical procedures... All scientific and technical information in this news release has been approved by Daniel MacNeil, PGeo, Technical Advisor to the Company. Mr. MacNeil is a qualified person for the purposes of NI 43-101.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The document identifies a 'Second Parallel Gold Trend' \(Sorpresa Trend\) adjacent to the known ADLP Trend, extending gold mineralization over an additional 4.9 kilometers.

> CopperEx Identifies Second Parallel Gold Trend Adjacent to the 7-Kilometer-Long ADLP Trend Returning 22 meters @ 0.59 g/t Gold at Sorpresa with Gold Mineralization over 4.9 Kilometers

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The trench intercepts are reported as 'INTERVAL \(m\)' or 'LENGTH' without any mention or estimation of true width or orientation relative to the mineralization.

Evidence · table

> INTERVAL \(m\)

Context: TRENCH NAME

**Deleterious Elements Present**

Polarity: negative

Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release.

Why it applies: Table 3 reports arsenic, antimony, and mercury values in rock samples, and the text mentions 'gold and arsenic anomalism' over the Sorpresa Trend.

## 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.
