## Minestarters Atlas summary

QMines has reported significant copper-rich drill intercepts at the Mt Chalmers project in Central Queensland, including 44m at 1.03% Cu. The drilling is intended to support the advancing Definitive Feasibility Study \(DFS\) through both geological data and fresh metallurgical samples.

Reasoning: QMines reported high-grade copper intercepts that support both geological expansion and metallurgical testing for an advancing DFS, alongside a solid existing resource base.

- Positive factor: Strong copper grades in new drill intercepts

- Positive factor: Drilling supporting DFS geometallurgical program

- Positive factor: Existing resource base provides project foundation

- Positive factor: Fully funded DFS via QIC package

- Negative factor: One hole abandoned due to stuck rods

Facts used in scoring: 19

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling returned a broad copper-rich zone beside the historic Mt Chalmers open pit.

Evidence · text

> struck a broad copper-rich zone beside the historic Mt Chalmers open pit

**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: Core recovery of 99.8% is explicitly reported for the main interval.

Evidence · text

> Core recovery across the 44m interval was 99.8%

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: Drilling is specifically designed to support the DFS geometallurgical program.

Evidence · text

> This drilling was primarily designed to support the DFS geometallurgical program

**Cut-off Disclosed**

Polarity: positive

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

Why it applies: A current resource fact retains the disclosed cut-off grade

Reasoning: Indicated portion of the 11.3Mt resource.

Evidence · text

> Mt Chalmers hosts an 11.3Mt resource averaging 0.75% copper and 0.42g/t gold at a 0.3% copper cut-off, comprised of 4.2Mt measured, 5.8Mt indicated and 1.3Mt inferred material.

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**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

**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

**No QP/CP Disclosure**

Polarity: negative

Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.

Why it applies: no Qualified or Competent Person is named anywhere in the release

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: the release names the study this estimate supports

Evidence · text

> Mt Chalmers hosts an 11.3Mt resource averaging 0.75% copper and 0.42g/t gold at a 0.3% copper cut-off, comprised of 4.2Mt measured, 5.8Mt indicated and 1.3Mt inferred material.

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**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

**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

**No QP/CP Disclosure**

Polarity: negative

Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.

Why it applies: no Qualified or Competent Person is named anywhere in the release

**DFS-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.

Why it applies: the release names the study this estimate supports

## 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.
