NioBay Metals Inc. (TSX-V: NBY) (OTCQB: NBYCF) is pleased to announce the start of a drilling campaign on the Crevier property, located approximately 50 km north of the town of Girardville and approximately 150 km from the Niobec mine. It is located within the Nitassinan territory of the Pekuakamiulnuatsh, whose main population center is Mashteuiatsh. The Project is easily accessible via existing logging roads.

The 2025 Campaign is made possible by a grant from the Ministère des Ressources naturelles et des Forêts (MRNF) under the Mining Exploration Support Program for Critical and Strategic Minerals. The drilling will be large in diameter (HQ) in order to collect a maximum quantity of material. Bulk sampling is also planned and will be combined with the drill core collected to produce a sample of more than 125 metric tons, representative of the extension zones.

NioBay is pleased to announce that this campaign will be carried out by the Premières Nations drilling company in Mashteuiatsh. Geological supervision has been entrusted to the Saguenay firm IOS Services Géoscientifiques. It should be noted that the latter was also involved in previous drilling campaigns on this site.

Message from NioBay’s President and Chief Executive Officer on Crevier

“This campaign will allow us to recover more material than during the 2023 campaign. In addition, this work will allow us to test the extensions of the known zone. Building on our first pilot plant, this campaign prepares us for our next pilot plant, which will be ten times larger than the first. We will use this second pilot plant to manufacture more product for our potential customers. Once again, we are pleased to carry out this work with the support of a local labor force, such as Forage Premières Nations of Mashteuiatsh and IOS Services Géoscientifiques of Chicoutimi,” says Jean-Sébastien David, President and CEO.
