North American Niobium talks radon survey results

Executive Summary

• Preliminary Phase 1 soil‑gas radon survey on the Blanchette and Bardy properties identified multiple anomalous “hot spots” that spatially coincide with known REE prospects (Blanchette‑1, Blanchette‑2, Bardy).
• The company will pair near‑real‑time radon targeting with a low‑impact portable backpack drilling program to obtain 2–3 m bedrock cores from identified hot spots, accelerating target generation for future diamond drilling.
• Phase 2 of the radon survey is slated for Q1 2026, expanding coverage on Blanchette, Bardy and Seigneurie properties; grid design and spacing are still under review.

Key Details

• Phase 1 Survey Execution: Conducted 16‑18 Dec 2025 by RadonEx.
• Bardy: 250 m × 250 m grid, 68 sampling points (anomaly threshold > 0.19 pCi/m²·s).
• Blanchette: Two 200 m × 200 m grids, total 72 sampling points (threshold > 0.15 pCi/m²·s).
• Anomalous Zones: Multiple radon hot spots observed near REE prospects; a west‑northwest‑east‑southeast trend interpreted at Bardy aligns with regional dike orientations from the Quebec MRNF Sigeom database.
• Targeting Rationale: Radon anomalies are used as a qualitative, early‑stage targeting tool to highlight potential extensions of pegmatitic granitic dikes that host REE and niobium mineralization.
• Backpack Drilling Program:
• Low‑impact, non‑hydraulic portable drilling capable of penetrating ≥ 20 m overburden.
• Expected recovery: ~2–3 m bedrock core per hole; 3–5 samples collected per day on average.
• Samples reviewed by a Quebec‑registered P‑Geologist before rush analysis.
• Phase 2 Plan (Q1 2026): Expand radon survey coverage to additional areas of Blanchette, Bardy and Seigneurie properties; final grid spacing under discussion.
• Regulatory Note: Backpack drilling is classified as prospecting activity and does not require an ATI permit in Quebec because it involves no hydraulic force.

Notable Quotes

“By combining near‑real‑time radon targeting with low‑impact, portable backpack drilling, we can rapidly recover bedrock core samples directly from the strongest radon hot spots – focusing our work where anomalies occur instead of broadly sampling across the entire property,” — Murray Nye, CEO, North American Niobium and Critical Minerals Corp.

Materiality Assessment: Non‑Material – Positive (early‑stage exploration data that is encouraging but does not yet constitute a material development).
