North American Niobium and Critical Minerals Corp. Advances Exploration
with Radon Soil-Gas Survey Underway at Blanchette and Bardy Projects
Vancouver, British Columbia – December 23, 2025 – North America Niobium and Critical Minerals
Corp. (CSE: NIOB) (FSE: IOR) (OTCQB: NIOMF) (“North American Niobium” or the “Company”) is
pleased to announce that it has initiated a soil-gas survey at its Blanchette and Bardy projects in Québec. The
survey is being conducted by RadonEx, an independent contractor and specialist geochemical services provider,
and commenced on December 16, 2025. The program is currently ongoing.
Highlights
Soil-gas survey initiated on December 16, 2025, and currently ongoing at the Blanchette and Bardy
projects, located approximately 40km north-west of the municipality of La Tuque
Survey comprises 82 sample points at Blanchette and 68 sample points at Bardy
Initial test designed to evaluate the responsiveness of the soil-gas method on the projects
The soil-gas survey represents an early-stage exploration activity intended to assess whether this geochemical
method can assist in refining exploration targets and detecting indications of niobium and/or rare earth element-
bearing granitic pegmatite systems beneath the over burden cover. Radon is a na turally occurring gaseous
element that forms as a result of the radioactive decay of uranium and thorium and can be measured within the
overburden cover. Thorite, a thorium-bearing mineral, has been identified in government thin section on the
Blanchette REE Prospect. No analytical results are being reported at this time.
“This program reflects a disciplined and methodical approach to advancing our Québec exploration portfolio.
The soil-gas radon survey is being undertaken as a targeted, early-stage test to evaluate whether this technique
can enhance our understanding of subsurface geology beneath overburden cover,” said Murray Nye, CEO of
North American Niobium and Critical Minerals Corp. “Given the presence of thorium-bearing minerals
identified in historic work at Blanchette, we believe this method has the potential to contribute meaningful
geochemical insight that could help refine targets and guide future exploration activities in a cost-effective
manner.”
The Company will evaluate the results of the survey once available and determine appropriate next steps in the
context of its broader exploration strategy.

ABOUT NORTH AMERICAN NIOBIUM AND CRITICAL MINERALS CORP.
North American Niobium and Critical Minerals Corp. is a North American mineral exploration company
focused on the acquisition and development of preci ous, base, and critical mineral assets. Its portfolio
includes the Silver Lake property in British Columb ia’s Omineca Mining Division and a recently acquired
land package in Quebec’s Grenville Province. The Quebec properties add exposure to rare earth elements
(REE), niobium (Nb), and nickel-copper (Ni-Cu) occu rrences, expanding the Company’s footprint into
critical minerals that are strategically important for energy and defense applications.

Forward-looking statements in this release include, but are not limited to: (i) statements regarding the
Properties and their mineral prospectivity; (ii) th e Company’s planned exploration, development and
evaluation activities on the Properties; (iii) the anticipated benefits of the Acquisition, including the expansion
of the Company’s exploration portfolio, increased exposur e to critical mineral targets, and the potential to
enhance long-term shareholder value; and (iv) the potential for the Grenville Province to host significant rare
earth element, niobium, nickel-copper or other critical mineral deposits. Such forward-looking statements are
based on the Company’s current plans, intentions, expectations and beliefs and are subject to certain
assumptions, including, without limitation, assumptions that required regulatory approvals will be obtained in
a timely manner, that financing will be available on reasonable terms, and that exploration results will continue
