## Minestarters Atlas summary

Tribeca Resources has reported a new discovery at its La Higuera IOCG Project in Chile, with the first drill hole \(CSS001\) into the Chirsposo Sur target intersecting 67m of 0.52% Cu and 0.15 g/t Au. This marks the third successful target drilled at the project, reinforcing the potential of the La Higuera district.

Reasoning: First drill hole into a new target \(Chirsposo Sur\) returned significant copper-gold mineralization, supporting the district-scale IOCG interpretation.

- Positive factor: New discovery under cover at Chirsposo Sur target

- Positive factor: Strong intercept of 67m at 0.52% Cu and 0.15 g/t Au

- Positive factor: High-grade sub-interval of 29m at 0.91% Cu

- Positive factor: Third of three targets at La Higuera to intersect mineralization

- Positive factor: Mineralization resembles known Gaby target

- Negative factor: True width of mineralized intersection is unknown

- Negative factor: Assays for remaining holes \(CSS002-CSS004\) are still pending

Facts used in scoring: 9

## 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: Release mentions field duplicates, standards, and blanks comprising 10% of samples.

Evidence · text

> utilizes field duplicates, standards and blanks

**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 true thickness of the mineralized intersection is explicitly stated as unknown.

Evidence · text

> true thickness of this mineralized intersection is unknown

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The hole CSS001 is the first into the new Chirsposo Sur target.

Evidence · text

> first drill hole into the Chirsposo Sur IOCG target

## 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.
