## Minestarters Atlas summary

Canstar Resources announced significant drill results from its Mary March VMS Project in Newfoundland, highlighted by a 15.6-meter intercept grading 2.3% copper equivalent, including higher-grade sections up to 3.9% CuEq. This represents the widest massive sulphide intercept in the project's history and confirms the geological model, with all four holes intersecting mineralization. The company plans further drilling to define the extent of the polymetallic VMS system.

Reasoning: Canstar Resources reported exceptional drill results from its Mary March VMS Project, including the widest massive sulphide intercept to date at 15.6m grading 2.3% CuEq, with higher-grade sub-intervals. The polymetallic nature and high grades are significant, and the results confirm the geological model and extend mineralization, indicating strong exploration potential. However, true width is not yet determined, and CuEq assumes 100% recovery.

- Positive factor: Widest massive sulphide intercept in project history

- Positive factor: High-grade copper equivalent results \(up to 3.9% CuEq\)

- Positive factor: Polymetallic VMS mineralization with significant base and precious metals

- Positive factor: All four holes intersected mineralization, confirming geological model

- Positive factor: Step-out drilling extends mineralized area

- Positive factor: Strong QA/QC disclosure

- Negative factor: True width not determined, reported as downhole length

- Negative factor: Metal equivalent calculation assumes 100% recovery for all metals

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

Facts used in scoring: 18

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept of 5.0 m at 3.9% CuEq is exceptionally high-grade for a VMS deposit, well above typical economic thresholds.

Evidence · table

> 3.9

Context: 5.0

**Apparent Width Only**

Polarity: negative

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

Why it applies: The document explicitly states that reported intervals are downhole lengths and true thickness has not been determined, with the full width of the fault-bounded massive sulphide not determined.

Evidence · text

> Reported intervals are downhole lengths. The true thickness of the mineralized material that was intersected is interpreted to be less than the downhole lengths of the intervals, and the full width of the original fault-bounded massive sulphide has not been determined; both will require further drilling.

**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 disclosure, mentioning ALS as an ISO/IEC 17025:2017 accredited lab, insertion of certified reference materials \(standards and blanks\), and QP sign-off.

Evidence · text

> Samples of sawn half core were prepared at the Canstar core shed facility in Millertown, Newfoundland and Labrador, packed in bags secured with heavy-duty, tamper-evident plastic seals, and shipped by commercial carrier to ALS in Moncton, New Brunswick. ALS Canada Ltd. is independent of Canstar and is accredited to ISO/IEC 17025:2017 and certified to ISO 9001:2015. Certified reference materials, consisting of four reference standards and two blanks, were inserted within every 100 samples.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drill hole MM-26-43 is described as a 'Step-out hole extends mineralized area' and the main intercept in MM-26-42 lies approximately 100 m along strike from a previously reported discovery intercept.

Evidence · text

> Step-out hole extends mineralized area: Drill hole MM-26-43 intersected the upper rhyolite contact at 478 m, approximately 130 m from hole MM-26-42 \(100 m deeper and 75 m to the southwest\), extending the altered rhyolite to the southwest

## 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.
