ATI Update for Seigneurie Project

Corporate Updates

North American Niobium and Critical Minerals Corp. Submits ATI Application

for Seigneurie Project in Québec, Advancing Path to Diamond Drilling

Vancouver, British Columbia – February 12th, 2026 – North American Niobium and Critical Minerals

Corp. (CSE: NIOB) (FSE: KS82.F) (OTCQB: NIOMF) (“North American Niobium” or the “Company”)

is pleased to provide an update on the permitting process in Québec for its 100%-owned Seigneurie Project (the

“Project”), located in the Municipality of Longue -Rive, Québec. The Company has submitted its initial

application for an Authorization for Impact-Causing Exploration Work (the “ATI”) to Québec’s Ministère des

Ressources naturelles et des Forêts (“MRNF”), which governs the ATI process. The ATI is required in Québec

prior to conducting certain impact-causing exploration activities, including diamond drilling.

Highlights

• Initial ATI application submitted to the MRNF for the Seigneurie Project (Longue-Rive, Québec).

• Québec’s ATI framework requires proponents to identify stakeholders and establish constructive

relationships through a formal information and engagement process.

• The Company has notified relevant parties in areas where the proposed drilling work may take place,

including the First Nation Council of the Innus of Essipit, the Municipality of Longue-Rive, and local

private landowners.

• The Company has received comments relating to potential access and other logistical considerations

(including suggested trail routes for drill rig access), which it will consider as it advances planning.

• Based on the Company’s current understanding of the process, the MRNF review may take

approximately 3 months, however timing is difficult to estimate given the number of stakeholder

groups identified (eight (8) in total) and the iterative nature of the ATI process.

• Even if an ATI is granted, the Company will still be required to finalize any necessary private access

and land-use agreements (where applicable) to access private property, and to continue working toward

long-term social acceptance through ongoing engagement, including alignment with the expectations

and protocols of the Innu community of Essipit.

Québec ATI Permitting Update

The submission of the ATI application represents an important step toward the potential future execution of a

diamond drilling program at the Seigneurie Project. Under Québec’s ATI framework, the MRNF review

process includes verification that the required stakeholder information exchanges have occurred and that

questions, comments, and requests raised through the process have been appropriately addressed.

The Company notes that the ATI process can be iterative and timelines may vary depending on the nature and

timing of feedback received and the time required to address project logistics. Accordingly, there can be no

assurance regarding the timing of the MRNF review or the eventual receipt of an ATI.

Stakeholder Engagement

The Company views stakeholder engagement as a core part of responsible exploration in Québec and expects

it to remain central to its activities at Seigneurie and any future projects in the province. The Company has

identified eight (8) stakeholder groups for the purposes of the ATI process and continues to progress discussions

and relationship-building efforts. Certain details of arrangements and discussions are not being disclosed at this

time.

“Establishing constructive, positive relationships with stakeholders is now a requirement under Québec’s ATI

permitting framework, and it takes time,” said Murray Nye, Chief Executive Officer of North American

Niobium. “We believe this is the new reality in Québec and one that is driving meaningful, positive change for

the mining industry. Our experience to date has been that people were glad to be consulted, and many, if not

all, want to see responsible projects succeed when they are approached with transparency and respect.”

Next Steps

The Company will continue to engage with stakeholders, respond to feedback received, and support the MRNF

review process as required. Any future impact -causing exploration work, including diamond drilling at

Seigneurie, remains subject to receipt of required approvals, including the ATI, and to ongoing planning and

stakeholder engagement.

Other Corporate Updates

North American Niobium also announces that Kelvin Lee has resigned as Chief Financial Officer, Corporate

Secretary and Director, and the Company thanks Mr. Lee for his contributions and service, with Steven Nguyen

appointed as his successor as Chief Financial Officer, Corporate Secretary and Director, effective immediately.
