North American Niobium and Critical Minerals Corp. Reports Positive

Preliminary Soil-Gas Radon Survey Results at Blanchette and Bardy; Phase 2

Planned with Rapid Follow-Up Portable Bedrock Drilling Program

Vancouver, British Columbia – January 8th, 2026 – North America Niobium and Critical Minerals

Corp. (CSE: NIOB) (FSE: IOR) (OTCQB: NIOMF) (“North American Niobium” or the “Company”) is

pleased to provide an update on its Phase 1 soil-gas radon survey completed by RadonEx on the Company’s

Blanchette and Bardy properties in Québec, located approximately 40 km northwest of the Municipality of La

Tuque. Preliminary results are positive, with multiple anomalous zones (“radon hot spots”) observed that are

spatially associated with the RE E mineral prospects Blanchette-1, Blanchette-2 and Bardy, and that may

suggest additional target areas are consistent with extensions of REE-bearing pegmatitic granitic dykes.

Highlights

• Multiple preliminary anomalous zones appear spatially associated with Blanchette-1, Blanchette-2 and

Bardy REE prospects.

• A preliminary WNW–ESE radon trend interpreted at Bardy is considered consistent with regional dyke

orientations reported by Québec government geologists (MRNF SIGEOM database).

• NIOB is integrating near-real-time radon targeting with a rapid follow-up backpack drilling program,

enabling the Company to act quickly on newly identified anomalous areas.

• NIOB plans a Phase 2 expansion of the radon soil gas survey in Q1 2026, increasing coverage to

additional areas of the Blanchette, Bardy and Seigneurie properties (grid sizing and spacing under

review).

Preliminary survey observations and interpretation

The Phase 1 soil-gas radon survey was completed by RadonEx from December 16–18, 2025 on the Company’s

Blanchette and Bardy properties, comprising one 250 m x 250 m grid at Bardy with 68 sampling points

(anomalous responses defined as >0.19 pCi/m²/s) and two 200 m x 200 m grids at Blanchette with 72 sampling

points (anomalous responses defined as >0.15 pCi/m²/s), each based on RadonEx thresholds. NIOB’s

preliminary interpretation is that several radon anomalies occur in proximity to known REE prospects on both

properties, and that the distribution of these “hot spots” may suggest extensions of pegmatitic granitic dykes

beyond currently mapped or prospected areas (Figures 1 and 2). The identification of pegmatitic dyke

extensions is significant, as these units are known to locally host or control REE and niobium mineralization

on the properties . At Bardy, the Company interprets a WNW –ESE trend in the anomalous pattern. The

Company notes that local access features (including a road) may have influenced signal continuity in places;

however, several anomalous responses were observed near the road corridor. A broader survey footprint and

expanded coverage may help resolve the trend and potential southwest extension at Bardy.

The Company emphasizes that these results are preliminary and qualitative at this stage. Radon anomalies are

being used as a targeting tool to help focus follow-up work, particularly in areas with overburden, and do not

confirm mineralization.

to be backpack drill tested this Q1 2026. Phase 2 will include the extension of this grid survey.

Real-time targeting and rapid follow-up sampling program

To maximize its de-risking strategy, NIOB is pairing the radon survey’s rapid turnaround (with data processed

and reviewed on a daily basis) with the addition of an extra prospecting team to follow up anomalous zones

soon after they are identified.

This follow-up work will include a low impact non-hydraulic portable backpack drilling service. The method

is designed to drill through 20m of overburden or more, where present, and recover approximately 2–3 m of

bedrock core for geological logging and sampling. The team is expected to collect approximately 3-5 samples

on average per day, depending on overburden conditions. Samples will be reviewed by a Quebec registered

P.Geo prior to selecting the most prospective pegmatite or carbonatite samples for rush analysis.

NIOB believes that combining daily/near-daily radon targeting with rapid follow-up sampling can help the

Company prioritize the most prospective areas for upcoming diamond drilling programs, rather than broadly

sampling the entire property package.

Phase 2 plan

Based on the spatial association observed between preliminary radon anomalies and known prospects, and the

interpreted WNW–ESE trend at Bardy, NIOB intends to advance to a Phase 2 radon survey expansion in Q1

2026, extending coverage to additional areas on the Blanchette and Bardy properties. Final grid design,

including spacing, remains under discussion.

The planned backpack drilling and sampling activity is considered low -impact and is being conducted as a

prospecting activity, the equipment doesn’t involve hydraulic force, which does not require an ATI permit in

Québec.

“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,” said Murray Nye, Chief Executive Officer of

North American Niobium. “Overburden is often under 10m for easy access; this method can drill 20m+ if

needed. Similar bedrock/basal till-style approaches have been used successfully by other groups, including

Kenorland, on a property-scale basis in Québec - this is one of the best ways to de-risk an exploration project

and generate quality drill targets.”
