## Minestarters Atlas summary

Andina Copper reported significant drill results from its Cobrasco Porphyry Copper-Moly Discovery in Colombia, highlighted by hole CDH010 intersecting 504m at 0.48% Cu. The results include high-grade sub-intervals up to 1.18% Cu and demonstrate continued lateral and vertical expansion of the mineralized system.

Reasoning: The drill hole CDH010 returned a very wide, high-grade copper-molybdenum intercept that expands the known footprint of the Cobrasco porphyry system.

- Positive factor: Significant width and grade intercept \(504m @ 0.48% Cu\)

- Positive factor: High-grade sub-intervals \(20m @ 1.18% Cu\)

- Positive factor: Expansion of mineralized footprint

- Positive factor: Strong continuity of mineralization

- Negative factor: Apparent width only \(no true width reported\)

Facts used in scoring: 11

## 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

> Samples were placed in plastic bags with non-repeatable sample tags

**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.
