## Minestarters Atlas summary

Aldebaran Resources reported significant drill results from its infill program at the Altar Copper-Gold Project in San Juan, Argentina, including 1,339.30 m of 0.45% CuEq and 1,059.20 m of 0.51% CuEq. These results aim to upgrade resource blocks to Measured and Indicated categories, demonstrating the size and quality of the deposit. The company also confirmed that intervals represent true thickness and provided detailed metal equivalent assumptions and QA/QC protocols.

Reasoning: The infill drilling program at the Altar Copper-Gold Project delivered multiple long and high-grade copper equivalent intercepts, confirming mineralization continuity and supporting the upgrade of inferred resources to higher confidence categories, which is a material de-risking step for the project.

- Positive factor: Long, high-grade copper equivalent intercepts demonstrate significant mineralization

- Positive factor: Infill drilling successfully confirms continuity and aims to upgrade resource categories

- Positive factor: True thickness of intervals is stated, providing higher confidence in geometry

- Positive factor: Detailed metal equivalent assumptions are disclosed, enhancing transparency

- Positive factor: Comprehensive QA/QC procedures are outlined, including certified lab and QP sign-off

Facts used in scoring: 24

## Classification and evidence

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document explicitly states: 'Intervals represent true thickness of the deposit.'

Evidence · text

> Intervals represent true thickness of the deposit.

**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 systematic and rigorous sampling and analytical protocols, including the use of certified standards, blanks, and duplicates, and mentions a certified ALS laboratory.

Evidence · text

> Altar follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards. ... Aldebaran independently inserts certified control standards \(Super Certified Reference Materials \(SCRM’s\), coarse field blanks, and duplicates into the sample stream to monitor data quality.

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.

Why it applies: Metal equivalent grade is reported with full disclosure of metal prices and recoveries used in the calculation.

Evidence · text

> CuEq values were calculated using copper, gold, silver, and molybdenum. Metal prices utilized for the calculations are Cu = US$3.00/lb, Au = US$1,400/oz, Ag = US$18/oz, and Mo = US$10/lb. Recoveries used for the supporting metals found in the CuEq equation are as follows: Au = 50%, Ag = 51%, \(based on historical metallurgical test work\) and Mo = 70% \(benchmarking from similar deposits\).

**Infill Drilling**

Polarity: neutral

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

Why it applies: The document explicitly states the program is an 'infill drilling program' with the goal to 'upgrade resource blocks classified as Inferred to the Measured & Indicated categories'.

Evidence · text

> results of seven holes from the infill drilling program at the Altar project in San Juan, Argentina. The goal of these holes was to upgrade resource blocks classified as Inferred to the Measured & Indicated categories.

## 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.
