NioBay Intercepts Niobium in the Extension of Its Main Zone at Crevier

NioBay Metals inc. (“NioBay” or the “Company”) (TSX-V: NBY) (OTCQB: NBYCF) is pleased to announce the first results of the Fall 2023 drilling program at its 72.5%-owned Crevier niobium & tantalum project (the “Crevier Project”). The Crevier Project is located about 50 km north of the town of Girardville and about 150 km from the Niobec mine. It is located on the Nitassinan (or ancestral territory) of the Pekuakamiulnuatsh, whose main population centre is Mashteuiatsh. This property is easily accessible via existing logging roads.

Update on the results of the 2023 drilling program on the Crevier ProjectThe Company completed a drilling program at the end of September 2023. The eight-hole campaign, spanning more than 2,700 m, tested the continuity of mineralization at depth and in the northwest and southeast sectors of the main zone. The Company has just received the first results from holes 23-001, 23-002 and 23-003. We are proud to have intercepted niobium more than 1 km from the main zone, in what appears to be its extension.

Offsetting our GHG emissionsTo compensate for the 42.21 tonnes CO2e of greenhouse gas (GHG) emissions generated during the drilling campaign and the regional exploration campaign, NioBay has made a contribution to Carbone Boréal (https://carboneboreal.uqac.ca), which will compensate by planting 305 trees in the province of Québec.

A word from the President and CEO of NioBay Metals about Crevier“We're delighted to announce these results, and in particular the intersections encountered in Hole 02, which is more than a kilometre from the main zone and, what's more, seems to demonstrate an extension of this zone," said Jean-Sebastien David, geo., President and CEO of NioBay. "Higher tantalum grades, compared with the resource calculation, were also intercepted in this same hole over more than 20 m. We're looking forward to the rest of the results.”

Following the completion of studies that indicate positive metrics for this project, the output at Crevier would be dedicated exclusively to the production of niobium oxide for battery manufacturers.

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 delivering other benefits such as better performance, improved safety and increased value.
