## Minestarters Atlas summary

Aldebaran Resources reported significant drill results from its Altar Copper-Gold Project in San Juan, Argentina, including a notable intercept of 1,728.9 meters at 0.45% CuEq, with a higher-grade section of 756 meters at 0.68% CuEq. These results are from an infill and geotechnical drilling program designed to upgrade inferred resources to higher confidence categories and support a pre-feasibility study. The company highlighted the immense scale of the Altar system and its potential for growth, with an updated mineral resource estimate and PFS planned for 2027.

Reasoning: The drilling program at the Altar Copper-Gold Project delivered exceptionally long and high-grade copper equivalent intercepts, confirming the immense scale of the porphyry system. These results are crucial for upgrading mineral resources and advancing towards a Pre-Feasibility Study, despite some intercepts being below the project's average grade and the presence of arsenic.

- Positive factor: Very long intercepts

- Positive factor: High CuEq grades for porphyry deposit type

- Positive factor: Infill drilling for resource upgrade

- Positive factor: Supports upcoming Pre-Feasibility Study

- Positive factor: QP/CP signed off on technical data

- Positive factor: QA/QC procedures disclosed

- Positive factor: Metal equivalent assumptions transparent

- Positive factor: True thickness reported for intervals

- Negative factor: Arsenic present as a deleterious element

- Negative factor: Some holes drilled for geotechnical purposes returned no reportable mineralization

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

#### Tags used in scoring

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: true\_width\_m is 112

**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: qaqc\_disclosed is true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Deleterious Elements Present**

Polarity: negative

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

Why it applies: deleterious\_flag is true

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: drill\_program\_type is "resource"

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "\# Aldebaran Reports 1,728.9 m of 0.45% CuEq \(0.41% Cu, 0.03 g/t Au & 1.34 g/t Ag\), including 756 m of 0.68% CuEq \(0.61% "

## 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.
