## Minestarters Atlas summary

Canterbury Resources Limited announced positive drilling progress at its Briggs and Monto copper-molybdenum-silver projects in central Queensland. At Briggs, the fourth hole of a major infill program returned a significant intercept of 383.8m at 0.25% Cu, 26ppm Mo, and 0.7g/t Ag, with the hole ending in mineralisation. This drilling aims to upgrade the Mineral Resource Estimate to support a Preliminary Feasibility Study. At the John Hill deposit \(Monto Project\), initial drilling indicates a northern extension of mineralisation, with assay results for the first hole anticipated in November.

Reasoning: The announcement provides new, significant drill results for the Briggs copper project, including a long, high-grade intercept, and reports progress on infill drilling aimed at upgrading the MRE for a PFS. Additionally, initial drilling at the John Hill deposit indicates a northern extension of mineralisation, with further results pending, suggesting future growth.

- Positive factor: Significant copper intercept at Briggs, with the hole ending in mineralisation, indicating potential for further extension.

- Positive factor: Briggs drilling is specifically aimed at upgrading the Mineral Resource Estimate \(MRE\) to support a Preliminary Feasibility Study \(PFS\), de-risking the project.

- Positive factor: Initial drilling at John Hill indicates a northern extension of the mineralisation system beyond current MRE limits, suggesting growth potential.

- Positive factor: The drilling program at John Hill is also testing western continuity of strong historical mineralisation.

- Positive factor: Both projects are reporting under JORC Code \(2012 edition\) with Competent Person sign-off, ensuring high reporting standards.

- Positive factor: Detailed QA/QC procedures are disclosed for both drilling programs, enhancing data reliability.

- Negative factor: Briggs drill intercepts are reported as downhole lengths and may not reflect true widths, which could overstate thickness.

- Negative factor: Assay results for the new John Hill drilling are pending, so the significance of the extension is not yet quantified.

- Negative factor: Some results cited are historical restatements, reducing their novelty.

Facts used in scoring: 27

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The main intercept of 383.8m at 0.25% Cu, including 76.7m at 0.34% Cu, is a very long interval with strong copper grades for a porphyry deposit, and the hole ended in mineralisation.

Evidence · text

> 383.8m at 0.25% Cu, 26ppm Mo & 0.7g/t Ag from 10.2m, including 76.7m at 0.34% Cu, 23ppm Mo & 0.8g/t Ag from 146.3m.

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Evidence · text

> Downhole intersections may not reflect true widths.

**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 JORC Table 1 sections for both Briggs and Monto projects, outlining sampling techniques, laboratory procedures \(ALS Laboratories\), and quality control measures such as standards, blanks, and duplicates.

Evidence · text

> Commercial standards alternating with a blank will be inserted every 25 samples. • Duplicates are created every 20 samples. • Quality control was assessed for this batch of assays, and all results were considered within acceptable limits.

**Compositing Transparent**

Polarity: positive

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

Why it applies: The document clearly states the criteria for significant intervals, including minimum length and maximum internal dilution: '>10m with a maximum internal dilution of 4m'.

Evidence · text

> Significant intervals reported are >10m with a maximum internal dilution of 4m \(some geological discretion\).

**Infill Drilling**

**Inferred Resource**

Polarity: negative

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

Why it applies: The historical MREs for Briggs and John Hill include significant tonnages classified as Inferred Resources, which have the lowest geological confidence.

Evidence · table

> 793

Context: Briggs

**Resource Update**

Polarity: neutral

#### Geometry

- Grade: 0.38
- Grade Unit: %
- Intercept: 14 m
- From: 371 m
- To: 385 m
- Intercept Depth: 371 m

#### Classification

- Deposit Type: porphyry
- Sample Type: drill
- Group ID: and:371-385
- Mining Method: open\_pit

#### QA/QC

- Laboratory: ALS Laboratories
- QA/QC Disclosed: Yes
- QP Signed: Yes
- QA/QC Methods: standards, blanks, duplicates

#### Compositing

- Dilution Disclosed: Yes

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2026-09-21T00:00:00.000Z

Reasoning: Expanded from assay table. 0.38 % copper is moderate against the porphyry deposit band \[0.8, 0.4, 0.25, 0.15\] %. Grade×width 5.3 %·m is below \(grade alone is moderate; the better of the two is used\).

- Negative factor: Scored from rubric bands during table expansion, not from document context.

#### 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

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2026-09-21T00:00:00.000Z

Reasoning: Expanded from assay table: 35 ppm molybdenum. No grade band defined for this commodity, so the score is a placeholder.

- Negative factor: No grade rubric for molybdenum; intercept not scored.

#### Geometry

- Grade: 0.31
- Grade Unit: %
- Intercept: 171 m
- From: 85 m

#### Classification

- Deposit Type: porphyry
- Sample Type: drill

#### QA/QC

- Laboratory: ALS Laboratories
- QA/QC Disclosed: Yes

#### Dates

- Event date: 2026-09-21T00:00:00.000Z

Reasoning: This intercept shows a strong copper grade over a moderate length, further enhancing the prospectivity of the Briggs deposit.

- Positive factor: Strong copper grade for a porphyry deposit, indicating a high-grade zone.

- Positive factor: Contributes to the overall mineralised footprint and resource upgrade.

- Negative factor: Downhole intersection may not reflect true width.

## 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.
