NIOBAY METALS ANNOUNCES ADDITIONAL MINERALIZED INTERSECTIONS
Montréal, Québec, November 18, 2025 - NioBay Metals Inc. (“NioBay” or the “Company”) (TSX-
V NBY) (OTCQB: NBYCF ) is proud to announce the latest results from the 2025 summer drill
campaign (the “2025 Campaign”) on the Crevier niobium (Nb) and tantalum (Ta) project (the
“Crevier Project”), of which it owns 72.5%. The Crevier Project is located approximately 50 km
north of the town of Girardville and approximately 150 km from the Niobec mine. It is located in
the Nitassinan (or ancestral territory) of the Pekuakamiulnuatsh, whose main population center
is Mashteuiatsh.
A Word from the President and CEO of NioBay Metals
“We are pleased to announce additional mineralized intercepts and the completion of the bulk
sampling,” said Jean-Sébastien David, P.Geo., President and CEO of NioBay. “This marks the end
of a very successful field season on the Crevier Project. We look forward to continuing to advance
this project, which will include carrying out a significantly larger pilot test (140 tonnes) compared
to the previous 10 -tonne test, and to furthering our discussions with potential customers
regarding the production of materials that meet their needs. We will now take advantage of the
winter season to carry out work on our James Bay Niobium property in Ontario.”
Following the completion of studies indicating positive parameters for this project, Crevier will
be exclusively dedicated to the production of niobium oxide for battery manufacturers.
Comprehensive and Final Results from the 2025 Campaign
The Company completed the 2025 C ampaign in August 2025. This 15 -hole campaign covered
3,324 m and was designed to v erify the continuity of mineralization in the northwest and
southeast sectors , among other things . This C ampaign was made possible thanks to the
participation of the Government of Québec through the Mining Exploration Support Program
for Critical and Strategic Minerals of the Ministère des Ressources naturelles et des Forêts
(MRNF). The Company can confirm that mineralized zones have been intersected in these latest
results from th is campaign. The complete results from 15 holes in these zones are presented
below. This information will be added to the historical information and will be used to update a
resource estimate. Mineralization is now confirmed over a strike length exceeding 6 km.
The Company also confirms that it has completed the bulk sampling as planned. More than
140 tonnes of rock from the mineralized zone were crushed and bagged for delivery to undergo
additional mineralogical testing.
