First American Uranium Discovers New Pegmatite Outcrop During
Site Visit; Confirms 27 km of Prospective Nb-REE Trends at
Seigneurie, Quebec
Vancouver, BC, October 29, 2025 – First American Uranium Inc. (CSE: URM) (FSE: IOR)
(OTCPK: FAUMF) (“First American Uranium” , or the “Company”) is pleased to announce
the successful completion of a site visit to its Seigneurie Property, located in the Regional County
Municipality of La Haute-Côte-Nord in Quebec’s Grenville Proterozoic Province. The visit was
conducted on October 22, 2025, by Murray Nye, Chief Executive Officer and Clyde McMillan,
Technical Advisor.
Purpose and Key Findings
The objective of the visit was to validate previous exploration work completed on the Seigneurie
Nb-REE prospect and assess ongo ing field programs. During the visit, the team discovered a
pegmatite outcrop, with a minimu m width of at least a 4-metr e-wide (Figure 1), exhibiting
mineralogical and geological characteristics similar to those of the main Seigneurie Prospect. The

elements. This outcrop is located 700m south-east of the Segneurie Nb-REE Prospect. The intrusion appears to strike
east-west and dips 45degrees to the south, with a minimum apparent thickness of 4-m identified on outcrop.

pegmatite contains quartz, feldspar, biotite and magnetite, and responds to the scintillometer. This
new outcrop extends the known footprint of the potentially mineralized Nb-REE system and
highlights the broader exploration opportunity across the property.
Currently, channel sampling, detailed geological mapping, and prospecting are underway across
the Seigneurie Property. Current geological inte rpretations made by the Company, integrating
regional airborne magnetic data with governme nt geological mapping, have delineated over 27
kilometres of prospective trends. These trends coincide with interpreted magnetic lineaments and
mapped quartz-syenite in trusions—favorable geol ogical settings for niobium and rare earth
element mineralization (Figure 2).
Figure 2: The Seigneurie Property is located near the St. Lawrence River coast, with a Hydro-Québec power line crossing
the property. Geological and geophysical interpretation has outlined approximately 27 km of prospective trends, exhibiting
characteristics similar to the 5 km-long highly prospective corridor hosting the Seigneurie Nb-REE prospect.

“Our recent site visit reinforces our view that the Seigneurie Property warrants continued
evaluation as a promising niobium and rare earth element exploration project” said Murray Nye,
CEO of First American Uranium. “ The scale of the mineralized system, combined with the
discovery of a new pegmatite exposure and 27kms of prospective trends, positions Seigneurie as a
truly exciting opportunity for th e Company. We are looking forw ard to advancing this project
through systematic exploration and unlocking its full potential.”
Clyde McMillan, P.Geo (OGQ#2193), Technical Advisor, added: “ The Seigneurie Nb-REE
prospect, previously explored for uranium and thorium, demonstrates strong potential for
niobium, rare earths, and potentially other critical elements. The width interpreted by SOQUEM
in 1978 of at least 50 metres, appears reasonable based on current field observations. Although
the true width is challenging to determine due to the outcrop’s extent, the geological continuity
and scale are encouraging indications for follow-up work.”
Next Steps
The Company’s field teams will continue mapping, sampling, and prospecting throughout the fall
season, with results to be announced once availabl e. These data will guide the next phase of
exploration, including potential drill targeting.
Strategic Advantages
The Seigneurie Property benefits from excellent infrastructure access, situated near the St.
Lawrence River and directly crossed by Hydro-Qu ébec power lines. These logistical advantages
provide strong support for future exploration and potential development activities.
ABOUT FIRST AMERICAN URANIUM INC.
First American Uranium Inc. is a North Ameri can mineral exploration company focused on the
acquisition and development of precious, base, and critical mineral assets. Its portfolio includes
the Silver Lake property in British Columbia’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) occurrences, expanding the Company’s
footprint into critical minerals that are strategically important for energy and defense applications.
