## Minestarters Atlas summary

CopperEx Resources Corp. announced results from a 7,902-meter surface trenching program at its Exploradora Norte Project in Northern Chile. The program, which included 29 trenches and 28 test pits at the ADLP and Sorpresa prospects, successfully defined the distribution of gold mineralization over significant widths. These results will be used to guide upcoming diamond drilling to expand the gold mineralized footprint.

Reasoning: The trenching program successfully delineated gold mineralization over significant widths at the ADLP and Sorpresa zones, providing critical data to guide upcoming diamond drilling. While individual gold grades are generally low, the broad intercepts and clear definition of the mineralized footprint are positive for advancing exploration, supported by robust QA/QC and QP sign-off. However, the lack of true width determination and the surface nature of the results temper the immediate impact.

- Positive factor: Significant widths of gold mineralization encountered

- Positive factor: Program successfully defined mineralization distribution for future drilling

- Positive factor: High quality QA/QC procedures disclosed and certified laboratory used

- Positive factor: Technical information approved by a Qualified Person

- Negative factor: Gold grades are generally low, with few intercepts exceeding 1 g/t

- Negative factor: True widths of mineralization are not yet determined

- Negative factor: Trenching is a surface exploration method, requiring follow-up drilling for depth extension

Facts used in scoring: 33

## 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 explicitly states that samples were sent to Andes Analytical Assay Spa. \('AAA'\) in Santiago Chile, which meets ISO 17025:2017 requirements, and CopperEx implements an internal QA/QC program including blanks, standards, and duplicates.

Evidence · text

> AAA meets all requirements of International Standards ISO 17025:2017 that includes ISO 9001 requirements for analytical procedures. Samples were analyzed using AAA's Fire Assay Fusion method \(AEF\_AAS\_1E42\) with an EAA finish for gold and by a 43-element four acid digest ICP-MS-OP analysis \(ICP\_AES\_HF43m\), and ICP\_AR01\_MS\_OP01 for mercury determination, with additional analysis for Ore Grade Au \(AEF\_GRV\_1E4\) and Ore Grade Cu \(4A\_HF\_AAS\_1E18SL\). Results are reported in parts per million \(ppm\) and converted to percent \(%\), or grams per tonne \(g/t\) where applicable. In addition to AAA Laboratory quality assurance - quality control \(QA/QC\) protocols, CopperEx implements an internal QA/QC program that includes inserting fine and coarse blank samples \(2.73%\), inserting OREAS series standards \(total 2.60%, including OREAS 153a, OREAS 523, OREAS 601c, OREAS 620, OREAS 502C\) and duplicate samples in the field and laboratory \(1.98%\), obtaining a total of 7.31% CopperEx QAQC control.

**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 document explicitly states that 'All intervals reported are core lengths, and true thicknesses are yet to be determined.'

Evidence · text

> All intervals reported are core lengths, and true thicknesses are yet to be determined.

**Cut-off Disclosed**

Polarity: positive

Story-specific tag

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The tables clearly list a 'CUT OFF \(ppm\)' column for all reported intercepts.

Evidence · table

> CUT OFF \(ppm\)

Context: GOLD \(g/t\)

**Low Grade**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: Many of the reported gold intercepts, particularly the broader ones, are below 0.3 g/t Au, which is considered weak for gold in a porphyry-epithermal setting.

Evidence · table

> 0.20

Context: 47.50

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The trenching program is described as defining the 'distribution of gold mineralization' and expanding the 'gold mineralized footprint' to guide upcoming diamond drilling, indicating an effort to extend known mineralization.

Evidence · text

> The results of the trenching campaign at Exploradora Norte more accurately define the distribution of gold mineralization at ADLP and Sorpresa which will be used to guide upcoming diamond drilling designed to expand the gold mineralized footprint defined by CopperEx's highly successfully inaugural RC drilling program completed earlier this year.

**Exploration Drilling**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The program is explicitly described as a 'follow-up trenching program' designed to 'map the surface expression' and 'define and geochemically characterize alteration features' to establish a 3D geological framework and guide future diamond drilling.

Evidence · text

> The objectives of the trenching were to 1\) map the surface expression of Sorpresa and ADLP gold mineralization, 2\) define and geochemically characterize alteration features north of ADLP and Sorpresa at the Oreganito zone and, 3\) place all three zones in a 3-dimensional geological framework to establish depth to gold mineralization from surface.

## 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.
