## Minestarters Atlas summary

Tarrina Resources announced highly positive Induced Polarisation \(IP\) survey results from its Walparuta Copper-Gold Project in South Australia, confirming a large-scale IOCG system extending over 4-5 km of strike and to depths of 350-500m. The survey identified numerous strong chargeability anomalies, with several exceeding 70 mV/V, which correlate well with existing magnetic, gravity, and copper-gold soil anomalies, significantly upgrading the project's discovery potential. These integrated geophysical targets define multiple high-priority drill targets, and the company plans to commence its maiden drill campaign once approvals are received.

Reasoning: The Induced Polarisation \(IP\) survey results significantly expand the known footprint and confidence in the Walparuta IOCG system, defining multiple high-priority drill targets over a substantial strike length and depth, validated by multi-disciplinary data and historical drilling. This substantially de-risks and advances the project towards its maiden drill campaign.

- Positive factor: IP survey confirms large-scale IOCG system over 4-5 km strike and 350-500m depth.

- Positive factor: Multiple high-intensity chargeability anomalies \(>42 mV/V, several >70 mV/V\) indicative of significant sulphide mineralization.

- Positive factor: IP results correlate strongly with copper-gold soil anomalism, magnetic, and gravity corridors, validating targeting.

- Positive factor: Historical drilling results plot precisely on IP anomalies, providing geological proof of concept.

- Positive factor: Defines multiple high-priority drill targets for upcoming maiden drill campaign.

- Negative factor: No new drill results are reported in this announcement, only historical data.

- Negative factor: Maiden drill campaign is still awaiting approvals, introducing timing uncertainty.

- Negative factor: Historical drilling QA/QC and sampling details are limited and not systematically documented.

Facts used in scoring: 28

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The IP survey results significantly expand the footprint of sulphide-bearing targets and confirm a 4 km strike extension of potential sulphide mineralisation.

Evidence · text

> The new results significantly expand the footprint of sulphide‑bearing targets. Multiple high‑intensity anomalies are now confirmed along to the west and east of the historic mine and add to the multiple targets to be tested by our maiden drill campaign.

**Nearology Play**

Polarity: neutral

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

Why it applies: The project is positioned in relation to known significant deposits in the region, such as Havilah Resources' Kalkaroo and Mutooroo deposits.

Evidence · text

> The region hosts several significant deposits, including Havilah Resources Kalkaroo and Mutooroo deposits, located approximately 50–80 km northeast and east of Walparuta.

**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 true widths of historical intersections were not determined and reported lengths are down-hole lengths.

Evidence · text

> True widths of intersections not determined. Reported lengths are down-hole lengths.

**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: The JORC table for historical drilling indicates that QAQC procedures, including standards, blanks, and duplicates, were not systematically implemented or documented.

Evidence · text

> QAQC procedures: Standards, blanks, and duplicates not systematically implemented

**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 presents historical drill results from previous operators, not new assays from the current IP survey.

Evidence · text

> Historic copper-gold drill results, including 36.6 m at 0.37% Cu and 0.27 g/t Au and soil copper and gold anomalies, coincide with the IP chargeability anomalies at the historic Walparuta Cu-Au mine, validating the use of IP chargeability geophysics to explore the wider regional magnetic and gravity corridors

## 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.
