Drilling Permit Bardy-Blanchette

Drill Results Marketing Announcement

NIOB Authorized to Drill at Two More Québec Projects

Fully permitted for diamond drilling on niobium and rare earth targets at Seigneurie,

Bardy and Blanchette

Vancouver, British Columbia – April 9, 2026 – North American Niobium and Critical Minerals

Corp. (CSE: NIOB) (FSE: KS82.F) (OTCQB: NIOMF) (“NIOB” or the Company) can launch maiden

diamond drill programs at Bardy and Blanchette, after receiving an Authorization for Impact -Causing

Exploration Work (ATI) for each project. Granted by Québec’s Ministère des Ressources naturelles et des

Forêts (MRNF), the ATI authorizes the Company to proceed with diamond drilling targeting niobium and

rare earth element mineralization at the 100% owned projects located approximately 45 km northwest of

La Tuque in the Mauricie region.

“We are now authorized to drill at three of our 100% owned projects in Québec: Bardy, Blanchette, and

Seigneurie,” said Murray Nye, the Company’s Chief Executive Officer. “ The Bardy and Blanchette

projects host high-grade rare earth and niobium mineralization in granitic pegmatites that have never been

tested by drilling. We look forward to building on the strong collaborative relationship we have established

with the Atikamekw community at Wemotaci as we advance toward our first drill program at these

projects.”

Highlights

• ATI drilling permit granted by Québec’s MRNF for the Bardy and Blanchette projects is valid for two

years and clears the path for diamond drilling.

• Located in the Mauricie region of Québec, the Bardy and Blanchette projects are 100% owned by North

American Niobium and part of the Company’s 36,882 -hectare district-scale land package in Québec’s

Grenville Province.

• NIOB met with the Atikamekw First Nation Council at Wemotaci and local family chief members whose

traditional territory includes the project area as part of ATI permitting framework

• Government sampling at Blanchette validated by the Company returned up to 2.70% total rare earth

elements (TREE) including 4,090 ppm neodymium, hosted in granitic pegmatite have never drill tested.

Québec ATI

The ATI permit authorizes NIOB to conduct diamond drilling and build access trails at the 100%-owned

Bardy and Blanchette projects. The permit was granted on March 24, 2026 and is valid for two years, through

to March 23, 2028.

Before granting an ATI, the Québec government requires companies to engage with local stakeholders and

Indigenous communities. NIOB completed discussions with the Atikamekw First Nation Council at

Wemotaci and local family chief members whose traditional territory includes the project area. The

Company has taken a collaborative approach to working on Atikamekw territory, recognizing the importance

of building long-term partnerships grounded in mutual respect and transparency. Among the items discussed

were logistical considerations, potential access routes, and opportunities for community involvement in

upcoming field programs.

The Company intends to use the ATI to advance its exploration strategy and initiate the first diamond drill

program targeting niobium and rare earth mineralization at the Bardy and Blanchette projects.

Geological Context and Exploration Target

The Bardy and Blanchette projects are located within the Grenville geological province, a region known for

hosting rare earth element and critical mineral occurrences. The project area contains REE- and niobium-

bearing granitic pegmatites identified through government geological mapping and sampling programs.

Government geologists collected outcrop samples from both the Blanchette and Bardy showings that

returned significant rare earth and niobium values. At Blanchette, sample 16- GC-1051E returned 26,967

ppm (2.70%) total rare earth elements including 4,090 ppm neodymium (Nd), hosted in a one-metre-wide

granitic pegmatite dyke cutting graphite paragneiss, with disseminated allanite and rare earth carbonates. At

Bardy, sample 16-AM-122D returned 6,848 ppm (0.68%) total rare earth elements including 1,150 ppm Nd,

hosted in a pegmatite dike (0.2–4 m wide) cutting gabbronorite, with disseminated allanite.

These showings have never been tested by diamond drilling. The upcoming drill program will be designed

to test the subsurface extent, continuity, and grade of the REE- and niobium-bearing pegmatite systems at

depth and along strike.

Grant of RSUs

The Company also announces that, pursuant to its Stock Option and RSU plans, it has granted a total of

320,000 restricted share units (“RSUs”) to an Advisory Consultant, subject to applicable regulatory approval

Canadian Security Exchange approval. Each RSU entitles the recipient to receive one Share common share

of the Company upon vesting. The RSUs will vest nine months from the date of grant.

Marketing Agreement

The Company announces that it has entered into a marketing services agreement (the “Marketing

Agreement”) with The New Beverley Group (“New Beverly”), for a period of three months commencing

April 10, 2026, paying $100,000 to New Beverly as compensation. N ew Beverly has a business address

located at 621 – 550 West Broadway, Vancouver, BC, V5Z 0E9 and its principal Justin Kuhn can be

contacted at +1 (905) 993-1271 or [email protected]. New Beverly and Mr. Kuhn are arm’s length

from the Company.
