## Minestarters Atlas summary

Canterra Minerals announced an updated Mineral Resource Estimate for its Lundberg Deposit, part of the Buchans Project in Newfoundland. The Indicated Mineral Resource increased by 55% to 26.1 Mt, with a 34% increase in contained copper equivalent. The estimate is pit-constrained, with 97% of the tonnage in the Indicated category, providing a strong foundation for future development.

Reasoning: The updated Mineral Resource Estimate shows a substantial 55% increase in Indicated tonnage and a 34% increase in contained copper equivalent, significantly de-risking the project. However, average grades for all metals have declined compared to the previous estimate, and the CuEq calculation relies on significantly higher metal prices.

- Positive factor: Significant increase in Indicated tonnage

- Positive factor: Significant increase in contained metal

- Positive factor: High confidence in resource category \(97% Indicated\)

- Positive factor: Pit-constrained resource

- Positive factor: QP signed off

- Positive factor: NI 43-101 compliant

- Positive factor: Cut-off grade disclosed

- Positive factor: Metal equivalent assumptions disclosed

- Negative factor: Average grades declined compared to prior estimate

- Negative factor: Metal prices used for CuEq calculation significantly higher than prior estimate

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

Facts used in scoring: 38

Evidence · text

> Mineral Resources are reported at a cut-off of US$20.40/t NSR

**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: Indicated Cu grade decreased by 14% from 0.42% to 0.36%, Zn grade decreased by 14% from 1.53% to 1.31%, Pb grade decreased by 13% from 0.64% to 0.56%, Ag grade decreased by 12% from 5.69 g/t to 5.02 g/t, Au grade decreased by 14% from 0.07 g/t to 0.06 g/t, and CuEq grade decreased by 13% from 1.00% to 0.87%.

Context: 0.36

**Resource Update**

Polarity: neutral

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

Why it applies: The document announces an updated Mineral Resource Estimate for the Lundberg Deposit, comparing it to a prior 2019 estimate.

Evidence · text

## 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.
