First American Uranium Discovers New Pegmatite Outcrop During Site Visit; Confirms 27 km of Prospective Nb-REE Trends at Seigneurie, Quebec

[{"type":"text","content":" Vancouver, BC, Oct. 29, 2025 (GLOBE NEWSWIRE) -- 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 ongoing field programs. During the visit, the team discovered a pegmatite outcrop, with a minimum width of at least a 4-metre-wide (Figure 1), exhibiting mineralogical and geological characteristics similar to those of the main Seigneurie Prospect. The 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.

The intrusion appears to strike east-west and dips 45degrees to the south, with a minimum apparent thickness of 4-m identified on outcrop. Currently, channel sampling, detailed geological mapping, and prospecting are underway across the Seigneurie Property. Current gGeological interpretations made by the Company, integrating regional airborne magnetic data with government geological mapping, have delineated over 27 kilometres of prospective trends. These trends coincide with interpreted aligned with interpreted magnetic lineaments and mapped quartz-syenite intrusions—favorable geological 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.
