## Minestarters Atlas summary

Sentinel Metals Limited has reported additional drill results from its 2026 program at the Columbia Gold-Silver Project in Montana, USA, confirming broad gold mineralization and extending it beyond the current Mineral Resource pit shell. Notable intercepts include 21.7m at 2.19g/t Au from DDCO26-011 and 9.1m at 2.56g/t Au from DDCO26-010, with some mineralization lying outside the existing pit shell. These results, along with pending assays for the final four holes, will be incorporated into an updated Mineral Resource Estimate in November 2026.

Reasoning: New drill results from the Columbia Gold-Silver Project confirm broad, shallow gold mineralization and extend it beyond the current pit shell, including bonanza grades. These results will feed into an updated MRE, indicating significant potential for resource growth. QA/QC procedures are well-documented, but assays are preliminary and true widths are not yet determined.

Facts used in scoring: 47

## 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 includes QA/QC disclosure with certified reference materials, blanks, and duplicates, and a Competent Person sign-off.

Evidence · text

> Certified reference materials \(OREAS 60e, 62h and 600c\), coarse quartz blanks \(submitted as 500g bags\) and duplicates \(quarter-core field duplicates, crushed-sample duplicates and pulp duplicates\) were inserted at a combined rate of approximately one QAQC sample for every four primary samples \(258 QAQC samples against 1,049 primary samples\).

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: Cut-off grade used for interval reporting \(0.3g/t Au\) and internal dilution rules \(up to 3m\) are clearly stated.

Evidence · text

> Significant intercepts for reported gold assays are calculated at a 0.3g/t Au lower cut-off and may include up to 3m of internal dilution

**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: Intervals are given as downhole widths with no true width or drill orientation stated.

Evidence · text

> Intervals are downhole lengths; true widths have not yet been determined.

#### Tags used in scoring

**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

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: cutoff\_grade and internal dilution are both stated

**Infill Drilling**

Polarity: neutral

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

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

#### Rejected tags

**Apparent Width Only** — Rejected; excluded from scoring

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Reason: Interval given as downhole width with no true width or drill orientation.

Evidence · text

> Intervals are downhole lengths; true widths have not yet been determined.

## 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.
