NioBay Intercepts Historical Grades on Its Crevier Project and Confirms the Extension of the Mineralized Zone

NioBay Metals Inc. (“NioBay” or the “Company”) (TSX-V: NBY) (OTCQB: NBYCF) is pleased to announce the latest results of the fall 2023 drilling campaign, on the Crevier niobium & tantalum project (the “Crevier Project”), of which the Company holds a 72.5% interest. 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.

Updated results of the 2023 drilling program on the Crevier ProjectThe Company completed a drilling campaign at the end of September 2023. This eight-hole campaign (2,700 m, consisted of verifying the continuity of the mineralization in the northwest, southeast and at depth sectors of the main area. The latest results of this campaign were received and we are taking the opportunity to highlight the important interceptions for the entire campaign. In addition, we have modified the hole identification numbers for the completed drill holes. The best intersections, using a cut-off of 0.2% (2000 ppm) of Nb2O5, have been presented, whereas a cut-off of 0.1% was used in the previous press release (January 8, 2024).

This campaign allows us to note the presence of tantalum mineralization in the northwest extension of the main zone and a higher concentration of niobium towards the southeast. In addition, the last hole shows mineralization, leaving this area open.

A word from the CEO, Jean-Sebastien David“We are pleased to announce the final results, and to note that the mineralized zone is open towards the southeast having intercepted mineralization in hole (18),” indicates Jean-Sébastien David, geo., president and CEO of NioBay. “Historic grades (highest grades over more than 1.5m since 2009) were intercepted in both niobium and tantalum, compared to drilling carried out to date at site. The Crevier Project has definitely not revealed all its secrets,” concludes Mr. David.

Crevier would be exclusively devoted to the production of niobium oxide for battery manufacturers.

About NiobiumNiobium 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.
