## Minestarters Atlas summary

Electric Metals \(USA\) Limited has filed a NI 43-101 Preliminary Economic Assessment \(PEA\) for the North Star Manganese Project in Minnesota. The PEA reports a robust after-tax NPV\(10%\) of US$1.39B and an IRR of 43.5%, based on an underground manganese mine and a high-purity manganese sulfate monohydrate \(HPMSM\) plant.

Reasoning: The filing of a PEA with a US$1.39B NPV and high IRR for a strategic critical mineral project represents a major technical milestone.

- Positive factor: Strong after-tax economics with 43.5% IRR

- Positive factor: High-grade manganese resource in a Tier-1 jurisdiction

- Positive factor: Strategic domestic U.S. supply for battery markets

- Positive factor: Integration of underground mine and chemical plant

- Negative factor: PEA stage carries high uncertainty and includes Inferred resources

- Negative factor: Flowsheet and unit costs to be finalized in PFS

Facts used in scoring: 1

## Classification and evidence

**PEA Only**

Polarity: neutral

Definition: Only Class 4 / Initial Assessment economics available. Not bankable.

Why it applies: The document announces a Preliminary Economic Assessment \(PEA\) which is a Class 4 study.

Evidence · text

> announces it has filed on SEDAR+ the National Instrument 43-101 Preliminary Economic Assessment \("PEA"\)

**High IRR**

Polarity: positive

Definition: Post-tax real unlevered IRR in the strong tier or better.

Why it applies: The reported IRR of 43.5% is in the exceptional tier.

Evidence · text

> IRR 43.5%

**Inferred Resource**

Polarity: negative

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

Why it applies: The PEA includes Inferred Mineral Resources, which limits economic confidence.

Evidence · text

> The Indicated and Inferred Mineral Resources used in the PEA operational and financial models are presented in Table 1.

## 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.
