NioBay Makes Its First Product Deliveries to Potential Customers/Partners

MONTRÉAL, June 03, 2025 (GLOBE NEWSWIRE) — NioBay Metals Inc. (“NioBay” or the “Company”) (TSX-V: NBY) (OTCQB: NBYCF) is proud to announce its first product deliveries from the SGS pilot plant in Québec City. This work was 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 for its Crevier niobium and tantalum project (the “Crevier Project”). 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. 

Grant

The grant titled: “Demonstration of the niobium-tantalum concentration process on a pilot scale and production of niobium and tantalum oxides from the Crevier Project deposit located in the Lac St-Jean region” allowed us to test the robustness of our process diagram. A first delivery to a potential customer/partner will allow us to verify, with this consumer, that our product can meet the specifications required by them. Other shipments will follow during the month to other potential customers/partners who have already indicated their desire to receive the product.

The Company will also distribute the concentrate to research partners involved in this project. These include Université Laval, CENET, and URSTM. These partners will conduct trials to test “unconventional” avenues for producing ANO (Niobium Ammonium Oxalate).

For the time being, the Crevier Project will focus exclusively on the production of niobium oxide for battery manufacturers and tantalum oxide for high-tech applications.

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

“We have just brought the Crevier Project to a new level in its history. These first deliveries to Europe are just the beginning. Consumer trials will allow us to continue the dialogue and work with these potential customers to deliver a product that meets their requirements. We hope our shareholders will be proud of this progress and we thank them in advance for their support,” concluded Mr. Jean-Sébastien David.

About Niobium

Niobium is a naturally occurring element. It is a metal that is ductile, malleable and highly resistant to corrosion. Because it enhances properties and functionalities, niobium is used in a wide range of materials and applications in the Mobility, Structural and Energy sectors. Niobium transforms materials. When added to materials like steel, glass and aluminum castings, niobium makes them more efficient and lowers environmental impacts, while also increased value.
