NIOB cuts target pegmatite in all Bardy holes

About this update from North American Niobium And Critical Minerals Corp.

Six of eight drilled across 500 m east-west area also carry rare earth minerals Vancouver, British Columbia, Aug. 04, 2026 (GLOBE NEWSWIRE) -- North American Niobium and Critical Minerals Corp. (CSE: NIOB) (FSE: KS82.F) (OTCQB: NIOMF) ("NIOB" or the "Company") has validated its radon targeting approach, after drilling at Bardy delivers a 100% hit rate for pegmatite dykes and a 75% hit rate for rare earth minerals. The pegmatite dykes were predicted from soil-gas radon anomalies at the Québec property. Hole BBY-2026-006 returned the strongest visual mineralization, including an eight-metre syenitic pegmatite (139.70 m to 147.70 m) with visible allanite. The hole ended in mineralized pegmatite, leaving the system open in all directions. All observations are from visual core logging; drill core is being sampled for laboratory analysis. "These visual observations confirm the targeting approach we are applying across our portfolio in Québec's Grenville Province," said Murray Nye, NIOB's Chief Executive Officer. "We used a radon survey to target the pegmatite and surface mapping to target rare-earth minerals. Every hole intersected pegmatite, and six of the eight holes carry visible allanite, with parisite logged in one hole. These are encouraging visual results, and we look forward to the assay results that will test the rare-earth tenor."  Highlights All Eight Holes Cut the Targeted Pegmatite Figure 1: Close-up of allanite-bearing syenitic pegmatite, hole BBY-2026-006, ~80.2 m.

All eight holes intersected the targeted syenitic-to-granitic pegmatite dykes, validating the radon-anomaly targeting model. Rare-earth-bearing minerals—principally allanite, with parisite in hole BBY-2026-001 and apatite/possible monazite locally—were also logged in six of the eight holes: BBY-2026-001, -003, -004, -006, -007, and -008. The two remaining holes cut the same target pegmatite carrying magnetite, without visible rare-earth minerals, confirming dyke continuity across the area drilled. Allanite was identified by comparison with government reference photographs of neodymium-praseodymium mineralized rocks from the district; in core it occurs as dark green, prism...
