## Minestarters Atlas summary

ATERRA Metals reported Phase I drill results from the Totora Cu/Au Project, featuring a substantial 284m intercept at 0.64% CuEq. The intercept includes a high-grade 180m section at 0.71% CuEq.

Reasoning: The intercept of 284m is very wide, providing significant continuity, though the CuEq calculation lacks disclosed assumptions.

- Positive factor: significant intercept width

- Positive factor: copper equivalent reported

- Negative factor: metal equivalent assumptions not disclosed

Facts used in scoring: 4

## Classification and evidence

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used.

Why it applies: The release reports CuEq grades but does not disclose the price or recovery assumptions used for the calculation.

Evidence · text

> grading 0.64% copper equivalent \("CuEq"\)

## 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.
