# NIOB Seigneurie Assays Confirm Niobium Mineralization in hole seven Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/niob-seigneurie-assays-confirm-niobium-mineralization-in-hole-seven--caf12a23-9288-4c5c-a14e-653aa2dde732 Original source: https://www.globenewswire.com/news-release/2026/07/21/3330337/0/en/niob-seigneurie-assays-confirm-niobium-mineralization-in-hole-seven.html Publisher: globenewswire Original announcement: 2026-07-21T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: North American Niobium and Critical Minerals Corp. - Ticker: NIOB - Exchange: Unavailable - Region: Québec - Primary commodity: Niobium - Secondary commodities: Copper - Document categories: Drill results - Extracted: 2026-08-20 21:04:28 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary North American Niobium and Critical Minerals Corp. has released final assay results for drill hole SGN-2026-007 at the Seigneurie Project in Québec. The hole returned significant niobium oxide intercepts and an unexpected copper zone deeper in the hole. Reasoning: Drill hole SGN-2026-007 confirms niobium oxide mineralization at grades similar to previous holes but with greater width, plus an unexpected copper intercept. - Positive factor: confirmed niobium mineralization - Positive factor: unexpected copper component - Positive factor: QA/QC disclosed - Negative factor: true widths not yet determined Facts used in scoring: 3 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions certified reference materials, blanks, and field duplicates, and names SGS Canada Inc. as an ISO/IEC 17025-accredited facility. Evidence · text > Quality control included certified reference materials, blanks and field duplicates **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document explicitly states that true widths have not yet been determined. Evidence · text > True widths have not yet been determined. ## Extracted facts Stored fact records: 3. Some facts used in scoring do not have a stored record. ## Drill Results (3) ### SGN-2026-007 [Link to this fact](https://atlas-staging.minestarters.com/news/niob-seigneurie-assays-confirm-niobium-mineralization-in-hole-seven--caf12a23-9288-4c5c-a14e-653aa2dde732#fact-drill-facts-0) Seigneurie · niobium #### Identity - Hole ID: SGN-2026-007 - Project: Seigneurie - Commodity: niobium - Region: canada\_qc - Reported Region: Québec - Ticker: NIOB #### Geometry - Grade: 842.3 - Grade Unit: ppm - Intercept: 10 m - From: 128 m - To: 138 m - Hole Depth: 290 m #### Classification - Program: exploration - Sample Type: drill - Group ID: SGN-2026-007:128.0-138.0 - Mining Method: unknown #### Location - Easting: 481680 - Northing: 5382081 - CRS: UTM NAD83 Zone 18 - Azimuth: 0 ° - Dip: 45 ° - Loc.

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.
