NIOB Expands Pegmatite System with Encouraging Niobium and Rare Earth Exploration Indicators
NIOB Pegmatite Expansion Validates Seigneurie Target; Assays Await Confirmation

Executive Summary
- North American Niobium and Critical Minerals Corp. reported drill hole SGN-2026-008 results at its Seigneurie project in Quebec on May 5, 2026.
- Hole intersected 108.60 metres of cumulative pegmatite over 218.6 metres drilled, consisting of ten stacked intervals.
- Thickest interval recorded was 42.15 metres (from 64.00 to 106.15 metres).
- Gamma-ray response peaked at 2,000–3,000 counts per minute, the strongest recorded on the project to date compared to ~1,400 cps in previous hole SGN-2026-007.
- Portable XRF (pXRF) screening identified elevated niobium (Nb), yttrium (Y), and phosphorus (P) within a brown mineral/magnetite assemblage.
- Samples submitted to SGS Canada Inc.; laboratory assay results are currently pending.
- CEO Murray Nye stated the hole adds to the belief of uncovering a large system at Seigneurie, with pegmatite occurring preferentially at the contact between amphibolite and gneiss host rocks.
Material Impact
- The news confirms the trend established in the April 29, 2026 release (Hole SGN-2026-007), validating the structural target hypothesis for the Seigneurie pegmatite system.
- While gamma-ray response is stronger than previous holes, the lack of definitive laboratory assay results limits immediate valuation impact; qualitative indicators remain speculative until lab confirmation.
- The stock price already reacted significantly to the April 29 announcement (rising from ~$0.50 to $1.32), suggesting this follow-up news is priced in as a continuation rather than a new catalyst.
- No change to capital structure or financing needs announced; exploration program remains fully funded for 2026 ($4.82M total flow-through).
- Rating reflects incremental progress within an active drill campaign rather than a fundamental shift in project economics without assay data.
