North American Niobium Receives Key Seigneurie Authorization

Executive Summary

• North American Niobium and Critical Minerals Corp. received an Authorization for Impact‑Causing Exploration Work (ATI) from Québec’s Ministère des Ressources naturelles et des Forêts, permitting diamond drilling at the 100 % owned Seigneurie Project.
• The ATI is valid for two years (until March 22 2028) and follows completed stakeholder engagement with local First Nations and municipalities.
• Historical drilling in the 1970s identified extensive pegmatite bodies; a new geological reinterpretation suggests a dike‑like intrusion >300 m wide, providing a significant target for niobium and rare‑earth element exploration.

Key Details

• Authorization: ATI granted on March 23 2026, authorizing impact‑causing activities such as drill‑access trail construction and diamond drilling.
• Project Location: Seigneurie Project, Haute‑Côte‑Nord region of Québec; 100 % owned by the Company.
• Stakeholder Engagement: Completed with Essipit Innus First Nation Council, Municipality of Longue‑Rive, and other parties per Québec ATI framework.
• Historical Data: 1970s drilling intersected 50–70 m pegmatite intervals; no REE or niobium assays were performed at that time.
• Geological Interpretation: Recent review of surface/drill data plus First Vertical Derivative (1VD) magnetic surveys indicates a pegmatite intrusion potentially exceeding 300 m in width, striking east‑west and open in all directions.
• Exploration Plan: Upcoming modern diamond drill program will test the scale, continuity, and mineralization potential of the interpreted pegmatite system for niobium and rare‑earth elements.
• Qualified Person: Clyde McMillan, P.Geo., has reviewed and approved the technical information in accordance with NI 43‑101.
