NIOB Bardy Assays Confirm Rare Earth Mineralization

Vancouver, British Columbia, Sept. 15, 2026 (GLOBE NEWSWIRE) — Assays from three more drill holes at North American Niobium and Critical Minerals Corp.’s (CSE: NIOB) (FSE: KS82.F) (OTCQB: NIOMF) (“NIOB” or the “Company”) Bardy property in Québec confirm previously announced visual observations . Holes BBY-2026-001, BBY-2026-002, and BBY-2026-005 have all intersected pegmatite. These assay results are in addition to those from BBY-2026-006, which intersected an 8.0-metre interval of syenitic pegmatite from 139.70 m to 147.70 m , including a 0.20-metre zone that included allanite in the core.

“The goal of our 2026 diamond drilling program at Bardy was to intersect niobium and rare earth bearing systems,” said Murray Nye, NIOB’s Chief Executive Officer, “and the latest results show that we are on the right track. Bardy’s eight holes were all collared at targets where radon data, high resolution magnetics, and surface mapping all intersect, and we’re pleased that the results continue to be validated.”

Note: Composite intervals were calculated with a cutoff grade of 0.1% TREO, and a maximum of 2 m of internal dilution.

Drilling and geological context Bardy is part of NIOB’s district-scale critical-minerals land package in Québec’s Grenville Province.

Holes BBY-2026-001 and BBY-2026-002 are located to the East of the Bardy showing, and hole BBY-2026-005 is located to the West (Figure 3). BBY-2026-001 and BBY-2026-005 were meant to test lateral continuity of Bardy’s mineralized dyke. BBY-2026-002 was testing a N110˚ radon anomaly trend.

All holes intersected sequences of intrusive rocks (from felsic to mafic) cutting through the gneiss. Small (< 3 m) pegmatite injections are seen in all three holes.
