## Minestarters Atlas summary

NioBay has released a new 2026 Mineral Resource Estimate for the Crevier project in Québec, incorporating recent drilling and metallurgical results. The update successfully converted 16.3 Mt of niobium-tantalum mineralization into the Measured category, a first for the project.

Reasoning: The update introduces Measured resources where none existed previously, significantly de-risking the project. The estimate is based on an optimized pit shell and includes recent drilling and metallurgical data.

- Positive factor: Category Upgrade

- Positive factor: QP/CP Signed

- Positive factor: NI 43-101 Compliant

- Positive factor: Cut-off Disclosed

Facts used in scoring: 8

## Classification and evidence

**Category Upgrade**

Polarity: positive

Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.

Why it applies: The update converted 16.257 Mt of resources into the Measured category, which was previously undefined.

Evidence · text

> convert 16,257,000 tons at 0,17 Nb₂O₅ and 201 ppm Ta₂O₅ into measured resources, whereas no measured resources had been defined in the previous estimate

**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: Jean-Michel Dubé, P.Geo., is named as the Qualified Person for the resource estimation.

Evidence · text

> Estimate performed by Jean-Michel Dubé, P.Geo., M.Sc. \| P.Geo., M.Sc., Qualified Person

**NI 43-101 Compliant**

Polarity: positive

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

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

Evidence · text

> prepared in accordance with National Instrument 43-101 \(NI 43-101\) Standards

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The cut-off grade is explicitly stated as 0.1124% Nb2O5 equivalent.

Evidence · text

> COG is of 0.1124% Nb2O5 equivalent

## 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.
