## Minestarters Atlas summary

Arika Resources Limited has announced the discovery of a new high-grade gold lode at its Kookynie Gold Project in Western Australia, approximately 200m down-plunge from historical mining at the Cosmopolitan Gold Mine. Drilling returned outstanding intercepts including 5m @ 12.34g/t Au, with a bonanza sub-interval of 1m @ 49.92g/t Au, from a previously unrecognised hangingwall structure. The company also reported encouraging high-grade results from other targets and plans further drilling at Kookynie and Yundamindra.

Reasoning: The announcement reports a new high-grade gold discovery with bonanza intercepts, extending mineralization significantly beyond historical workings, supported by robust QA/QC and JORC compliance. The 5m at 12.34 g/t Au \(61.7 g/t\*m\) is a strong result, and the 1m at 49.92 g/t Au sub-interval is exceptional, exceeding the project's best historical grade x metres. This discovery opens up a large, high-priority target area.

- Positive factor: Bonanza Intercept

- Positive factor: True Width Disclosed

- Positive factor: Step-Out Extension

- Positive factor: QA/QC Disclosed

- Positive factor: Compositing Transparent

## 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 detailed QA/QC procedures, including the use of Intertek Laboratory, QP sign-off, and methods like blanks, standards, and duplicates.

Evidence · text

> All of the samples being reported on in this release were collected utilising industry standard Reverse Circulation \(RC\) drilling techniques... All samples described in this announcement have been submitted to Intertek Laboratory in Kalgoorlie... Field duplicates, blanks and CRM standards were inserted every 25 samples... The information that relates to Exploration Results is based upon and fairly represents information compiled by Mr Steve Vallance, who is a shareholder and full-time employee of Arika Resources Ltd in the role of General Manager Exploration and Executive Technical Director. Mr Vallance is a Member of The Australian Institute of Geoscientists \(AIG\). Mr Vallance has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” \(the JORC Code 2012\).

**Compositing Transparent**

Polarity: positive

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

Why it applies: The release clearly states the cut-off grades used for compositing \(0.1 g/t Au for low-grade, 0.5 g/t Au, 5.0 g/t Au, and 10.0 g/t Au for high-grade\) and the maximum internal dilution \(generally 4m\).

Evidence · text

> Intercepts were defined geologically based on an interpretation of the target zone at a given location. Length weighted grades were then calculated based on a sample returning an assay value of greater than 0.1 g/t Au for the low-grade envelope and internal zones of greater than 0.5 g/t Au and 5.0 g/t Au respectfully. Generally, no more than 4 metres of internal material that graded less than 0.1 g/t Au was included except where a Raft or ‘Horse’ of lower grade country rock was interpreted as being within the targeted lode zone as defined by adjacent holes.

#### 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

#### Rejected tags

**Bonanza Intercept** — Rejected; excluded from scoring

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Reason: The grade of 12.34 g/t Au over 5m is strong, and the sub-interval of 49.92 g/t Au is exceptional for orogenic gold deposits.

Evidence · text

> 5m @ 12.34g/t Au including 1m @ 49.92g/t Au

**True Width Disclosed** — Rejected; excluded from scoring

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Reason: The document states that drilling was designed to intersect the target zone orthogonal to both strike and dip, meaning the downhole length is close to the true thickness.

Evidence · text

> Drilling was designed as perpendicular as possible to the interpreted structure that hosts mineralisation to avoid introducing any bias. The downhole length is therefore close to the true thickness.

**Step-Out Extension** — Rejected; excluded from scoring

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Reason: The new high-grade lode was discovered approximately 200m down-plunge of the main area of historical mining, extending the known mineralization.

Evidence · text

> New high-grade gold lode discovered at the historical Cosmopolitan Gold Mine, ~200m down-plunge of the main area of historical mining.

#### Rejected tags

**Bonanza Intercept** — Rejected; excluded from scoring

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Reason: The grade of 8.24 g/t Au over 4m is strong for orogenic gold deposits, approaching the exceptional threshold of 15 g/t Au for underground mining.

## 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.
