## Minestarters Atlas summary

Eastport Critical Metals has reported positive Phase One infill drilling results at the Matsitama Copper Project in Botswana, confirming thick copper mineralisation exceeding 100m in multiple holes. The results validate historical continuity at the Nakalakwana deposit and support future NI 43-101 compliant resource updates.

Reasoning: Phase one infill drilling successfully confirmed thick \(>100m\) copper mineralisation at the Nakalakwana deposit, validating historical continuity with high-grade sub-intervals.

- Positive factor: thick copper-rich mineralisation

- Positive factor: intercepts exceeding 100m

- Positive factor: confirms historical continuity

- Positive factor: QA/QC disclosed

- Negative factor: historical resource is not current

- Negative factor: historical resource is SAMREC compliant not NI 43-101

Facts used in scoring: 15

## 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 ALS-Chemex South Africa's ICP-AES analytical technique.

Evidence · text

> obtained using ALS-Chemex South Africa's ICP-AES analytical technique

**Infill Drilling**

Polarity: neutral

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

Why it applies: The program is described as Phase One infill drilling to validate historical results.

Evidence · text

> Phase One infill drilling has successfully confirmed

**Historical Estimate Only**

Polarity: negative

Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.

Why it applies: The document discusses a 2013 SRK resource that is not considered current.

Evidence · text

> Eastport does not consider the 2013 SRK Consulting \(South Africa\) Pty Limited \("SRK"\) mineral resource as current.

## 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.
