## Minestarters Atlas summary

OceanaGold reports exceptional high-grade gold drill results from its Wharekirauponga project in New Zealand, including intercepts of 6.3m at 97.2 g/t Au and 8.5m at 41.5 g/t Au. These results demonstrate continuity and up-dip extension of the high-grade EG Vein zone, supporting future resource upgrades and reserve increases. The company is also progressing with the Waihi North Project, including a potential processing plant expansion to 1.2 Mtpa to enable concurrent mining of the Martha Underground and Wharekirauponga Underground mines.

Reasoning: OceanaGold reports exceptional high-grade gold drill results from Wharekirauponga, including 6.3m at 97.2 g/t Au and 8.5m at 41.5 g/t Au, demonstrating strong continuity and extension of the EG Vein zone. These results are expected to support resource upgrades and reserve increases in an upcoming technical report, alongside plans for a processing plant expansion. The high grades and continuity are very positive, though one hole had poor core recovery.

- Positive factor: Exceptional high-grade gold intercepts

- Positive factor: Demonstrated continuity and up-dip extension of high-grade zone

- Positive factor: Drilling supports upgrade of Inferred to Indicated resources and increased reserves

- Positive factor: Planned processing plant expansion to support concurrent mining

- Negative factor: Reduced core recovery in one significant intercept \(WKP146D EG Vein\)

- Negative factor: Upcoming technical report is forward-looking, not current results

Facts used in scoring: 15

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 6.3 m @ 97.2 g/t Au is exceptionally high-grade, well above the typical threshold for gold deposits.

Evidence · text

> 6.3 m @ 97.2 g/t Au from 481.5 m, East Graben \("EG"\) Vein \(WKP146C\)

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 1.2 m @ 107.7 g/t Au is exceptionally high-grade, well above the typical threshold for gold deposits.

Evidence · text

> incl. 1.2 m @ 107.7 g/t Au

**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 certified labs, use of blanks, standards, and duplicates, and QP sign-off.

Evidence · text

> Quality Assurance and Quality Control \("QA/QC"\) All exploration samples are assayed for gold by 30g fire assay with Atomic Absorption Spectrometry \("AAS"\) finish.

**True Width Disclosed**

Polarity: positive

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

Why it applies: The drill results table explicitly provides 'True width \(m\)' for each intercept.

Evidence · table

> True width \(m\)

Context: WKP145A

**Infill Drilling**

Polarity: neutral

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

Why it applies: The drilling program is explicitly described as an 'exploration and resource conversion program' and 'resource conversion' is listed as the activity for the drill holes.

Evidence · text

> ongoing exploration and resource conversion program at Wharekirauponga

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drilling is focused on 'growth-oriented step-out drilling along strike of the EG Vein, reflecting the substantial upside that remains in this open, unconstrained vein system.'

Evidence · text

> drilling through the remainder of 2026 will focus on both resource conversion and growth-oriented step-out drilling along strike of the EG Vein

**Deleterious Elements Present**

Polarity: negative

Definition: A source-stated penalty, refractory or recovery concern in the fact's scope. Element detection alone, including measured elements explicitly below penalty thresholds, does not trigger this tag. Respect negation and retain a separately stated concern even when another risk is explicitly absent.

Why it applies: The QA/QC section mentions that samples post-April 2024 are analyzed for Ag, As, Sb, Hg, and S, indicating the presence of these elements in the ore.

Evidence · text

> Samples post-April 2024 with Ag, As, Sb, Hg and S by ICP-MS after DIG12R Digest

## 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.
