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 factors
- Category Upgrade
- QP/CP Signed
- NI 43-101 Compliant
- Cut-off Disclosed
Facts used in scoring: 8

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.
