## Minestarters Atlas summary

Great Western Mining Corporation PLC has completed its 23-hole reverse circulation drilling campaign at the Defender Tungsten Project in Nevada, USA, totaling approximately 2,590 meters. Geological logging and shortwave ultraviolet inspection confirmed the presence of scheelite-bearing skarn across several wide intervals in multiple drillholes, consistent with previous surface sampling. Samples have been dispatched to an accredited laboratory for assay, with results expected in Q4 2026, which will inform a maiden Mineral Resource Estimate.

Reasoning: Great Western Mining Corporation PLC has completed its RC drilling campaign, intersecting multiple wide intervals of visually identified scheelite-bearing skarn, which is encouraging and consistent with surface sampling, but quantitative assay results are pending.

- Positive factor: Drilling campaign completed as planned

- Positive factor: Visual scheelite mineralization observed in multiple wide intervals

- Positive factor: Consistency of subsurface observations with prior surface sampling

- Positive factor: JORC compliant reporting and QP/CP sign-off

- Positive factor: Accredited laboratory used for assays

- Negative factor: No quantitative assay results reported yet

- Negative factor: Mineralization based on visual estimates, not assays

- Negative factor: Recovery data not assessed for potential bias

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 3

## 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: The release includes a detailed JORC Code table outlining sampling techniques, quality control procedures \(CRMs, blanks, duplicates\), and states that an accredited laboratory \(American Assay Laboratories\) was used, with sign-off by Competent Persons.

Evidence · table

> AAL is an accredited laboratory. Standard four acid digest and multi-element ICP analysis.

Context: Quality of assay data and laboratory tests

**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 reported intervals are given as downhole lengths \(e.g., '100 ft \(31 m\) of continuous skarn'\) without any mention of true width or drill orientation relative to mineralization, implying these are apparent widths.

Evidence · text

> Drilling intersected 100 ft \(31 m\) of continuous skarn from 50 ft \(15 m\) to 150 ft \(46 m\) depth

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The primary objective of the drilling was to 'link historic workings between the Defender and Pine Crow mines, across an approximate strike length of around 1 km,' indicating an effort to extend known mineralization.

Evidence · text

> Primary objective of the drilling was to link historic workings between the Defender and Pine Crow mines, across an approximate strike length of around 1 km.

**Visual Mineralization**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The mineralization is reported based on visual inspection using shortwave ultraviolet \(SWUV\) to identify scheelite, rather than quantitative assay results, which are pending.

Evidence · text

> Shortwave Ultraviolet confirms that multiple holes intersected scheelite bearing skarn across wide intervals

## 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.
