## Minestarters Atlas summary

Cobra Resources plc announced an update on its slim-line RC drilling program at the Manna Hill Copper Project in South Australia. Preliminary visual observations and pXRF readings indicate a significant extension of the Blue Rose mineralisation by 600m to over 2.2km strike and the discovery of two new skarn systems, Shadow Rose and Neptune Rose. While no laboratory assay results are yet available, the company highlights the potential for a substantial resource, with assays expected in 4-6 weeks.

Reasoning: The announcement indicates significant potential for scale and new discoveries based on preliminary visual and pXRF data from an ongoing drill program, but definitive assay results are pending. Historical results are provided as context.

- Positive factor: Blue Rose strike extended to beyond 2.2km

- Positive factor: Two new mineralised skarn systems identified at Shadow Rose and Neptune Rose

- Positive factor: All three zones remain open

- Positive factor: The objective of this campaign is to establish a shallow mineralised footprint of the size required to support a substantial resource

- Positive factor: QP/CP Signed

- Positive factor: JORC Compliant

- Negative factor: Visual observations and pXRF readings... are not a substitute for laboratory assay results.

- Negative factor: No reliance should be placed on them as an indication of grade, tenor or economic significance.

- Negative factor: First assays expected in 4-6 weeks

- Negative factor: Downhole intercept lengths have been reported and are expected to be greater than true length.

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

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling program has extended the Blue Rose strike length by 600m to beyond 2.2km.

Evidence · text

> Blue Rose strike extended to beyond 2.2km - broad copper anomalism intersected approximately 600m west of previously known mineralisation at Blue Rose, extending the copper-bearing corridor from ~1.6km to beyond 2.2km in strike

**New Discovery**

Polarity: positive

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The drilling identified two new mineralised skarn systems at Shadow Rose and Neptune Rose.

Evidence · text

> Two new mineralised skarn systems identified at Shadow Rose and Neptune Rose

**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 extensive JORC Table 1 details on sampling techniques, quality control procedures, and laboratory analysis, including the use of standards, blanks, and duplicates.

Evidence · table

> Commercially certified reference material of known copper grades and of suitable matrix were included in the laboratory assay sequence at a rate of 1 per 50 samples. · First-split duplicate samples were collected at a rate of 1 per 50 samples. · A coarse blank sample was inserted 1 in every 50 samples.

**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 document explicitly states that downhole intercept lengths are reported and are expected to be greater than true length.

Evidence · text

> Downhole intercept lengths have been reported and are expected to be greater than true length.

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: For historical drilling, the document states that historic sampling has not been assessed.

Evidence · table

> Historic · Historic sampling has not been assessed.

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The document includes historical drill results from 'earlier drilling' and 'deeper intersections indicative of a much larger porphyry system at depth' as background information, not new assays.

Evidence · text

> earlier drilling has: · Confirmed mineralisation along 1.6km of strike within a calc-silicate skarn containing shallow high-grade intersections including:

**Exploration Drilling**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The program is described as a 'low-cost, high-tempo test of the extent' and aims to 'establish a shallow mineralised footprint of the size required to support a substantial resource'.

Evidence · text

> The programme is a low-cost, high-tempo test of the extent of the Blue Rose mineralised corridor, and in its first 23 holes it has significantly extended the Blue Rose skarn system along strike and identified copper mineralisation in two new skarn systems not previously drilled.

**Visual Estimates Only**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The assessment of mineralization is based on visual observations and handheld pXRF, with laboratory assays pending.

Evidence · text

> The assessment of mineralisation has to date been done visually from drill chips and via handheld pXRF. First assays expected in 4-6 weeks

Reasoning: This historical sub-interval shows a low gold grade, providing minor context to the polymetallic nature of the mineralization, but it is not new information.

- Negative factor: Apparent Width Only

- Negative factor: Stale Data Re-release

Evidence · text

> 0.13 g/t Au

#### 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

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: the fact restates a prior release

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: proximity is offered as the value premise: "Highlights: · Blue Rose strike extended to beyond 2.2km - broad copper anomalism intersected approximately 600m west of "

## 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.
