North American Niobium to Fly Airborne Survey Over Four Quebec Properties

Executive Summary

• North American Niobium and Critical Minerals Corp. is advancing its 2026 exploration program across its Québec district-scale portfolio, with active drilling underway at the Bardy and Blanchette properties and a second drill rig scheduled to mobilize in early July.
• The company plans a mid-June airborne radiometric and magnetic survey over four key properties (Bardy SE, Miskam, Sabot, Blanchette) to identify REE and Nb mineralization, while integrating satellite-derived radon and helium soil-gas data into its target generation workflow.
• The 2026 drill program totals approximately 10,000 metres across four phases, including a completed winter program at Seigneurie (~2,000m) and a flexible final tranche retained for high-priority targets identified from new geophysical and geochemical data.

Key Details

• Drilling Progress & Plans: ~1,500 metres planned at Bardy and ~1,500 metres at Blanchette (currently underway). Seigneurie winter program is complete at ~2,000 metres (assays pending).
• Future Mobilization: A second drill rig will mobilize in early July 2026 for an additional ~2,500 metres of drilling, with target sequencing informed by the mid-June airborne survey and soil-gas results.
• Flexible Tranche: ~2,500 metres retained as a flexible final tranche to be deployed against the highest-priority targets emerging from the integrated dataset.
• Total Program Scope: The 2026 drill program totals ~10,000 metres, structured across four distinct phases.
• Geophysics & Geochemistry: Mid-June airborne radiometric and magnetic survey planned over Bardy SE, Miskam, Sabot, and Blanchette to identify radiometric responses associated with REE- and Nb-bearing pegmatite, syenite, and alkaline intrusive systems. Satellite-derived radon and helium soil-gas estimates from independent consultants are being integrated to support targeting beneath overburden.
• Intrusion-Style Targets: Miskam hosts an interpreted ~60 km² intrusion of the Veillette Intrusive Suite, spatially associated with one of the largest Nb-REE bottom-lake-sediment anomalies in the region. Bardy SE targets the Toad Intrusive Suite (dated 981.6 Ma), which is age-equivalent to the Crevier Alkaline Complex (~957 Ma) hosting the Crevier Nb-Ta deposit. Seigneurie targets a large pegmatite-syenite intrusive body with potential widths exceeding 200 metres.
• Dyke & Vein-Style Targets: Bardy features granitic pegmatite dykes ranging from 40 cm to 4 metres in width along a ~7-kilometre prospective trend. Blanchette and Sabot target structurally controlled pegmatite dyke and vein swarm systems.
• Strategic Advisory & Options: Ian Mallory engaged as a strategic advisor for a two-year term. Granted 150,000 stock options exercisable at $1.06 per share for a five-year period, subject to regulatory approval.
• Local Engagement: Current drilling phase is supported by local Atikamekw service providers.

Notable Quotes

• “Our 2026 program is on track and our data pipeline is filling out as we hoped,” said Murray Nye, CEO. “The mid-June airborne radiometric and magnetic survey, combined with the radon and helium soil-gas datasets we are building, will sharpen our target picture across Bardy SE, Miskam, Sabot, and Blanchette before we deploy the next 2,500 metres of drilling in early July. By holding back the last 2,500 metres as a flexible tranche, we keep optionality to put steel into the most prospective ground once the new geophysics and geochemistry are in hand.”
