NIOB LAUNCHES DIAMOND DRILL PROGRAM AT SEIGNEURIE

Drills are turning for the first time at North American Niobium and Critical Minerals Corp.'s Seigneurie project.

"The team has wasted no time. We announced receipt of the key authorization last week, and the drill is already running this week. This first phase is designed to test the extension of the pegmatite system and evaluate its potential to host niobium and rare-earth mineralization," said Murray Nye, North American Niobium's chief executive officer. "The results will help guide the next stage of exploration at Seigneurie."

Highlights

• Diamond drilling has commenced at the 100-per-cent-owned Seigneurie project in Quebec.
• Initial drill holes are designed to test the extension of the pegmatite system at both the edge and core of the target area.
• Program will evaluate the potential for niobium (Nb) and rare-earth element (REE) mineralization associated with the pegmatite system.
• The 2026 drill campaign at Seigneurie is fully financed.

Seigneurie project

The fully financed diamond drilling program follows North American Niobium's previous geological work at its 100-per-cent-owned property in the Haute-Cote-Nord region of Quebec and will initially test the scale and continuity of the interpreted pegmatite system.

Initial holes are designed to test the extension of the pegmatite system for potential niobium and rare-earth element mineralization at both the edge and core of the system. Approximately 1,800 metres over nine holes have been planned, but additional metres may be added subject to results.

Drilling is being conducted by Forage Fusion Drilling Ltd., and the company will release assay results in timely fashion after they have been received and analyzed.
