## Minestarters Atlas summary

Itafos has completed an updated Preliminary Economic Assessment \(PEA\) for the Arraias Phosphate Project in Brazil, reporting a total Mineral Resource of 5 Mt \(2 Mt M&amp;I and 3 Mt Inferred\). The PEA indicates a robust project with an 85% IRR and an after-tax NPV of $70.7 million USD.

Reasoning: The updated PEA demonstrates strong economic potential for the Arraias Project with high IRR and NPV, supported by a substantial mineral resource estimate.

- Positive factor: Robust economic indicators \(85% IRR, $70.7M NPV\)

- Positive factor: Significant resource scale \(5 Mt total\)

- Positive factor: NI 43-101 compliant PEA

- Positive factor: Existing production at Domingos deposit

- Negative factor: High sensitivity to product sales price

- Negative factor: Inferred resource component is significant \(3 Mt\)

- Negative factor: Technical risks regarding scale-up and hardness

Facts used in scoring: 6

## Classification and evidence

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The PEA was prepared in accordance with NI 43-101 standards.

Evidence · text

> prepared... in accordance with National Instrument 43-101

**Inferred Resource**

Polarity: negative

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

Why it applies: A significant portion of the resource \(3 Mt\) is in the Inferred category.

Evidence · text

> plus 3 Mt Inferred Mineral Resources

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Jennifer Simper, P.Geo. is named as the Mineral Resource Qualified Person.

Evidence · text

> The Mineral Resource Qualified Person \(“QP”\), Jennifer Simper, P.Geo.

## 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.
