North American Niobium and Critical Minerals Corp. Confirms Magnet REE and Niobium Mineralization at Blanchette, Bardy and Sabot Properties
Including 1.82% TREO and 0.14% Nb?O?North American Niobium and Critical Minerals Corp. (CSE: NIOB) (FSE: KS82.F) (OTCQB: NIOMF) ("North American Niobium" or the "Company") is pleased to report geochemical results from select rock grab samples collected during its Q4 2025 prospecting program on the Company's 100%-owned Blanchette, Bardy and Sabot properties in Québec, located approximately 40 km from the Municipality of La Tuque. The results confirm the presence of magnet rare earth elements and niobium within pegmatite-hosted systems, reinforcing the Company's thesis that its Québec portfolio is prospective for critical minerals essential to clean energy, electrification, and defense applications.
Highlights
- Blanchette: A select outcrop rock grab sample returned 1.82% TREO, including 3,979.41 ppm MREO (2,892.67 ppm Nd?O?, 935.15 ppm Pr?O??, 123.95 ppm Dy?O? and 27.64 ppm Tb4O7) and 0.14% Nb?O?.
- Bardy: A select outcrop rock grab sample returned 0.319% TREO, including 682.50 ppm MREO.
- Sabot: A select outcrop rock grab sample returned 0.155% TREO, including 313.12 ppm MREO.
- Next steps: At Bardy and Blanchette, the Company plans follow-up soil-gas radon surveying conducted in tandem with a backpack drilling program. A separate high-resolution magnetic survey is also planned to further define and prioritize target areas.
MREO: Magnet Rare Earth Oxide; TREO: Total Rare Earth Oxide; TREE: Total Rare Earth Elements
Q4 2025 Prospecting Program and Results
The Q4 2025 program consisted of reconnaissance prospecting and selective outcrop sampling across the Blanchette, Bardy and Sabot properties to validate historical grab assay results and guide follow-up exploration. The results reported in this release are derived from select outcrop rock grab samples, which are selective by nature and may not be representative of underlying mineralization. The Company collected 98 samples at Bardy, 86 samples at Blanchette, and 15 samples at Sabot during its 2025 Fall Program. The twenty (20) best assay results shown in Table 1 below were collected from granitic rocks, predominantly pegmatite, located approximately 40 km northwest of the Municipality of La Tuque. These encouraging results were selected because they exceed either the 0.10% TREO threshold or 500 ppm Nb?O?. Notably, pegmatite sample G170126 from Blanchette returned 0.48% Cu and 158.53 ppm Nd?O?.The Company also confirmed that the 2.7% TREE sample (including 4,090 ppm Nd) was a channel sample collected across the full 40 cm width of the dyke. The historical Bardy sample (0.69% TREE total, including 1,150 ppm Nd) could not be located. The identification of elevated magnet REEs and niobium in surface samples across multiple properties supports the presence of a fertile mineral system within the Grenville Province. These results provide a technical basis to advance toward subsurface validation and systematic target delineation.
Table 1: Best assay results from the Q4 2025 prospecting program on Blanchette, Bardy and Sabot. Twenty (20) assay results are above 500 ppm Nb2O5 or TREO above 0.1%.

Notes:
- TREO (%) includes Y?O?.
- MREO (ppm) is the sum of Nd?O? + Pr?O?? + Dy?O? + Tb?O?.
- Grab samples are selective and no sample widths are implied. Rock grab samples are not necessarily representative of mineralization hosted on the properties.
Planned Follow-Up Work
The Company plans to advance priority areas at Bardy and Blanchette with a soil-gas radon survey conducted in tandem with a low-impact backpack drilling program to validate radon anomalies associated with mineralization and refine targets. A separate high-resolution magnetic survey is also planned to further define and prioritize target areas and guide subsequent exploration.
Sampling and Analytical Methods
Rock grab samples were collected from outcrop during the Q4 2025 prospecting program and submitted to ALS Laboratories in Lachine, Québec for analysis. Samples were analyzed using ALS method ME-MS71L, which includes ammonium bifluoride (ABF) decomposition / near-total extraction with ICP analytical techniques for multi-element geochemistry.
The Company did not insert certified reference materials, blanks, or field duplicates as part of this reconnaissance-level selective rock grab sampling. ALS employs internal quality control procedures as part of its analytical protocols. The data has been reviewed by the Qualified Person.
"These results validate our geological thesis across multiple Québec properties and confirm the presence of magnet rare earth elements and niobium in key target areas," said Murray Nye, Chief Executive Officer of North American Niobium. "With high-priority zones now identified at Blanchette, Bardy, and Sabot, we are moving decisively into follow-up programs designed to test continuity and scale."
