North American Niobium Highlights 0.150% Nb2O5 with124.53 ppm Dy2O3 from Pegmatite Grab Sample and 0.19% TREO from REE-BearingCarbonatite Outcrop at Seigneurie, Quebec

Executive Summary

• North American Niobium reported high‑grade assay results from Phase 1 channel sampling and Phase 2 selective grab sampling on its 100% owned Seigneurie Project in Québec.
• A pegmatite grab sample returned 1,502 ppm Nb₂O₅ (0.1502%) with 124.5 ppm Dy₂O₃ and notable Ta, Hf, Sc concentrations; a carbonatite outcrop yielded 0.19% TREO.
• The company is advancing Québec permitting to support planned drilling in Q1 2026, indicating continued development of a potentially sizable niobium‑REE system.

Key Details

• Pegmatite Grab Sample (G170343) – 1,502.02 ppm Nb₂O₅ (0.1502%); 0.1348 % TREO; 124.52 ppm Dy₂O₃; 34.80 ppm Ta₂O₅; 16.57 ppm HfO₂; 16.25 ppm Sc₂O₃; HREO/TREO ratio = 0.94%.
• Carbonatite Grab Sample (G170310) – 0.19 % TREO; 31.10 ppm Dy₂O₃.
• Phase 1 Channel Sampling – 15.0 m composite interval returned 294.39 ppm Nb₂O₅ and 0.039 % TREO (incl. 28.66 ppm Dy₂O₃, 11.30 ppm HfO₂).
• Sampling Scope – Phase 1 conducted 25‑27 Oct 2025; two N‑S channels totalling 94.5 m across exposed pegmatite outcrop. Phase 2 comprised 109 selective grab samples covering additional pegmatite and carbonatite exposures.
• Geological Interpretation – Pegmatite strikes ~N80°, steeply dipping south, open along strike, width, and depth; surface exposure suggests possible >150 m apparent width pending drill verification. Historical 1978 drill collars located nearby support a wider intrusion hypothesis.
• Next Steps – Pursuing Québec exploration permits; integrated geochemical‑structural work underway to prioritize targets for Q1 2026 drilling campaign.
• Analytical Methods – Samples processed by ALS Laboratories (crushing, pulverizing, 70 % >2 mm, 85 % >75 µm); analyses via ME‑MS71L, ME‑MS85, etc.; duplicate analysis program initiated at a second lab for QA/QC.

Notable Quotes

“Phase 1 channel sampling only tested the limited outcrop available at surface, and while the grades are modest, the results consistently show notable niobium, dysprosium, hafnium and scandium.” – Murray Nye, CEO
“Phase 2 has now returned a very encouraging pegmatite grab sample grading 0.15% Nb₂O₅ with notable dysprosium, hafnium and scandium… Given the current market interest and pricing environment for dysprosium, hafnium and scandium, this is an intriguing metal mix and warrants further work as we advance permitting and prepare for drilling in 2026.” – Murray Nye, CEO

Materiality Assessment: Material – Positive (significant assay results indicating a potentially economically viable niobium‑REE system and imminent drill program).
