## Minestarters Atlas summary

Andina Copper reported significant drill results from its Cobrasco Porphyry Copper-Moly discovery in Colombia, highlighted by a 504m intercept at 0.48% Cu in hole CDH010. The results confirm the lateral extent and continuity of the mineralization, expanding the delineated footprint to approximately 1,200m.

Reasoning: The drill hole CDH010 returned a very wide 504m intercept with strong copper grades, extending the known mineralized footprint of the Cobrasco porphyry system.

- Positive factor: significant intercept width

- Positive factor: high grade near surface

- Positive factor: step-out extension

- Positive factor: continuity confirmed

- Negative factor: apparent width only

Facts used in scoring: 13

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The company is using substantial step-outs to delineate the lateral extent of the discovery.

Evidence · text

> using substantial step-outs to delineate the lateral extent

**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 the sampling, preparation, and assaying protocols, including the use of an accredited laboratory \(ALS\).

Evidence · text

> All sampling was conducted in nominal 2m intervals... Samples were placed in plastic bags... sent to the ALS sample preparation facility

**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 interval widths are measured down-hole and uncorrected.

Evidence · text

> Interval widths are measured down-hole and uncorrected. They do not necessarily represent true widths

## 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.
