## Minestarters Atlas summary

MGX Resources Limited has released its Mineral Resources Statement as of June 30, 2026, detailing gold mineralization at its 50%-owned Central Tanami Project Joint Venture \(CTPJV\) and remaining iron ore at its wholly-owned Koolan Island mine. The company's attributable gold resources from CTPJV total 1.4 million ounces, marking its first inclusion in MGX's statement. Conversely, Koolan Island's iron ore resources have significantly decreased to 3.3 million tonnes at 59.3% Fe, with no remaining Ore Reserves, reflecting mining depletion and a major rockfall, leading to its planned divestment.

Reasoning: The company is reporting its annual mineral resource statement, which includes a significant new gold resource from an acquired joint venture, indicating future growth potential. However, it also details a substantial reduction and planned divestment of its iron ore assets due to operational challenges, marking a shift in its commodity focus.

- Positive factor: Acquisition of 50% interest in Central Tanami Project Joint Venture \(CTPJV\) adding 1.4 Moz attributable gold resources.

- Positive factor: CTPJV gold resource is substantial \(2.8 Moz on 100% basis\) and is being progressed to a development decision.

- Positive factor: All resource estimates are JORC 2012 compliant and signed off by Competent Persons.

- Negative factor: Significant reduction in Koolan Island iron ore resources due to mining depletion and a major rockfall.

- Negative factor: No Ore Reserves remain at Koolan Island.

- Negative factor: Planned divestment of Koolan Island means MGX will no longer hold iron ore resources.

- Negative factor: Some gold deposits within CTPJV are identified as potentially refractory, which may impact processing.

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

Facts used in scoring: 120

## Classification and evidence

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: The Central Tanami Project Joint Venture \(CTPJV\) gold resources are included for the first time in MGX's annual statement.

Evidence · text

> This annual statement includes for the first time Gold Mineral Resources of 31.0 Mt grading 2.8 g/t Au for 2.8 Moz contained gold within the CTPJV \(100% basis\).

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The Koolan Island iron ore resources are an update compared to the prior year's statement, reflecting depletion and changes.

Evidence · text

> Remaining Mineral Resources at Koolan Island total 3.3 Mt of iron ore \(hematite\) grading 59.3% Fe, all located within the Mangrove deposit \(2025: Mineral Resources totalled 9.7 Mt grading 63.2% Fe within both the Main and Mangrove Deposits\).

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: All gold and iron ore Mineral Resources are reported in accordance with the JORC Code \(2012 Edition\).

Evidence · text

> This statement details the Mineral Resources and Ore Reserves estimates of MGX as at 30 June 2026 in accordance with the JORC Code \(2012 Edition\) and ASX Listing Rules.

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Competent Persons are named and have provided written consents for both the gold and iron ore estimates.

Evidence · text

> MGX has engaged appropriately qualified Competent Persons to act on its behalf in relation to the CTPJV... The Competent Persons have provided their written consents approving the inclusion of the Mineral Resource estimates... The information in this report relating to hematite Mineral Resources at Koolan Island is based on information compiled by Ms Elizabeth Haren, a Competent Person...

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The inclusion of 1.4 Moz attributable gold from CTPJV represents a significant increase in the company's overall contained gold metal.

Evidence · text

> MGX acquired its 50% CTPJV interest in February 2026, giving it an equity attributable share of 1.4 Moz of contained gold.

**Contained Metal Decline**

Polarity: negative

Definition: Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.

Why it applies: Koolan Island's contained iron metal has significantly decreased due to tonnage and grade reductions from 9.7 Mt at 63.2% Fe to 3.3 Mt at 59.3% Fe.

Evidence · text

> Remaining Mineral Resources at Koolan Island total 3.3 Mt of iron ore \(hematite\) grading 59.3% Fe... \(2025: Mineral Resources totalled 9.7 Mt grading 63.2% Fe...

**Tonnage Decline**

Polarity: negative

Definition: Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down.

Why it applies: Koolan Island's iron ore tonnage decreased from 9.7 Mt in 2025 to 3.3 Mt in 2026.

Evidence · text

> Remaining Mineral Resources at Koolan Island total 3.3 Mt of iron ore \(hematite\)... \(2025: Mineral Resources totalled 9.7 Mt...

**Grade Decline**

Polarity: negative

Definition: Average grade dropped &gt;5% vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling.

Why it applies: Koolan Island's iron ore grade decreased from 63.2% Fe in 2025 to 59.3% Fe in 2026.

Evidence · text

> Remaining Mineral Resources at Koolan Island total 3.3 Mt of iron ore \(hematite\) grading 59.3% Fe... \(2025: Mineral Resources totalled 9.7 Mt grading 63.2% Fe...

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: A significant portion of both gold and iron ore resources are classified as Inferred, indicating lower geological confidence.

Evidence · table

> Inferred 1.2 58.2 13.70 0.97 0.038

Context: 1.2

**Refractory Ore**

Polarity: negative

Story-specific tag

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: Some gold deposits within the CTPJV are identified as potentially refractory, which may require more complex and costly processing.

Evidence · text

> Note 1: Deposits containing fresh material have been identified as potentially refractory; therefore, the applied cut-off grades incorporate additional costs and adjusted recovery factors to reflect the production and sale of a gold concentrate.

#### Tags used in scoring

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: category is "inferred"

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: cutoff\_grade is stated

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: qp\_signed is true

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: reporting\_standards includes jorc

**No Contained Metal**

Polarity: negative

Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.

Why it applies: contained\_metal was not reported

**Tonnage Decline**

Polarity: negative

Definition: Resource tonnage decreased vs prior estimate — pit optimization removed marginal material or geological model revised down.

Why it applies: 3300000 against 6100000 previously

**Grade Improvement**

Polarity: positive

Definition: Average resource grade improved vs prior estimate — better deposit economics.

Why it applies: 12.21 against 5.22 previously

## 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.
