## Minestarters Atlas summary

Decade Resources has intersected porphyry-style copper mineralization in its first deep drill hole \(DDH 1\) at the Bonaparte property. The hole passed through a classic propylitic-to-potassic alteration sequence, confirming the presence of a buried porphyry system beneath a known chargeability anomaly.

Reasoning: The hole successfully intersected the predicted porphyry alteration zonation and mineralization, providing significant geological validation, though economic grades are unconfirmed pending assays.

- Positive factor: geological confirmation of porphyry model

- Positive factor: intersection of potassic alteration and mineralization

- Positive factor: first deep test of chargeability anomaly

- Negative factor: no assay results yet

- Negative factor: visual observations only

Facts used in scoring: 2

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: First hole ever drilled to test beneath the high chargeability anomaly, testing a new target area.

Evidence · text

> first hole ever drilled to test beneath a high chargeability anomaly

**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 assays will be performed by MSA LABS and reviewed by a Qualified Person.

Evidence · text

> assays to follow from MSA LABS

## 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.
