North American Niobium and Critical Minerals Corp. Completes Phase 1 Fall Prospecting Program; Carbonatite and Pegmatite Targets Identified Across Quebec Properties

Executive Summary

• North American Niobium and Critical Minerals Corp. completed its Phase 1 Fall 2025 prospecting, mapping, and channel‑sampling program on four 100 % owned Québec properties (Seigneurie, Bardy, Blanchette, Sabot).
• Field crews collected 262 grab and channel samples—including 94.5 m of channel sampling on the Seigneurie property—and identified new carbonatite boulders and multiple REE‑bearing pegmatite zones.
• Assay results are pending; they will be released after laboratory analysis by ALS Laboratories.

Key Details

• Program Duration: October 13 – November 5, 2025.
• Technical Team: Five‑person team (three prospectors, two geologists) from Grassroots Prospecting & Target Generation Inc. and McMillan Geosciences Inc.
• Sampling Summary: 262 grab/channel samples; 94.5 m of channel sampling on Seigneurie (average sample length ≈ 1.5 m).
• Geological Highlights:
• Carbonatite boulders discovered at Blanchette, adjacent to a circular magnetic anomaly on regional airborne geophysics.
• Two carbonatite areas identified: new occurrence at Blanchette and confirmation of a REE‑anomalous carbonatite subcrop on Seigneurie (previously reported by Québec Ministry of Natural Resources & Forestry in 2015).
• Numerous pegmatites with REE potential confirmed on Seigneurie.
• Lithology Observed: Pegmatites, carbonatites, mafic intrusives, volcanics, metasedimentary units, gneiss.
• Analytical Work: All samples submitted to ALS Laboratories (Lachine, Montréal). Methods include:
• ME‑MS71L for REE‑bearing granitic pegmatite and carbonatite.
• PGM‑23 & ME‑MS61 for mafic/ultramafic units prospective for Ni‑Cu‑PGE mineralization.
• Assay Status: Results pending; will be released after review by the Company’s technical team.
• CEO Comment: Murray Nye stated the program “significantly improved our understanding of the geological framework” and that the new targets support the view of meaningful critical‑mineral potential.
