Press release

TSX-V: NBY & OTCQB:NBYCF

CORPORATE UPDATE OF NIOBAY ACTIVITIES

Montreal, Québec, December 14, 2022 – N io Bay Metals Inc. ( “NioBay” or the “ Company”)

(TSX-V: NBY) (OTCQB: NBYCF) is pleased to announce the completion of the exploration work

on the “extension” at the Crevier Project (the “Crevier Extension”) , its participation in a

research project with the University of Quebec at Trois-Rivières (“UQTR”) and its implication

with the Minister's Mining Industry council (“MMIC”) in Ontario.

Completion of exploration work at the Crevier Extension

The Company completed the 2022 drilling campaign on the Crevier Extension (the “Drilling

Campaign”). The exploration work was carried out within the planned schedule and the initial

plan was to drill 12 holes ( 3,250 metres). The Drilling Campaign ended with a total of

4,000 metres spread over 10 holes. Th e modification to the plan ned campaign was dictated

by observations made in the field throughout the campaign and the Company expects to

receive laboratory results by the end of the year.

Reception of the petrographic report

The Company received a petrographic report (digital petrography of 6 polished thin section

with artsection technology) from IOS Services Géoscientifiques to identify the minerals

encountered in certain mineralized zones from the Drilling Campaign.

This report indicates that N iobium (“Nb”)-bearing minerals were detected. T hese are:

pyrochlore, Ellsworthite, pyrochlore -microlite, rutile -Nb, illmenite and titanite. Carbonates

and feldspathoids of interest were also identified such as: carbonate -REE, burbankite,

nepheline and sodalite. The complete report will be posted on our website.

In order to offset the 81. 3 t CO 2 eq. in greenhouse gas ( GHG) emitted during the D rilling

Campaign, Niobay made a contribution to Carbone Boréal (https://carboneboreal.uqac.ca)

who will compensate by planting 584 trees in the province of Quebec.

NioBay and UQTR research project

NioBay is proud to announce its participation in a research project with UQTR. This project

will focus on the “ Development of a new porous niobium -based transport layer for water

electrolysis by proton exchange membrane”.

Hydrogen is one of the most efficient energy carriers and can be produced by various

methods. Among them, proton exchange membrane water electrolyzer ( “PEMWE”) is

considered the most promising technique to produce very pure hydrogen from renewable

energy sources with pure oxygen as a by-product, without carbon emission.

The porous transport layers (“PTL”) must meet certain requirements to work inside the cell,

such as good electrical and thermal conductivity, high corrosion resistance, minimal contact

resistance and low mass transport losses. Niobay and UQTR will develop a new N iobium-

based PTL for the PEMWE that will meet all these criteria. This project was made p ossible

thanks to the participation of PRIMA Qué bec and the Natural Sciences and Engineering

Research Council of Canada (NSERC).

It should be noted that N iobium is seen as a potential substitute for the commonly used

platinum group elements (PGE).

Invitation to join Ontario’s MMIC

NioBay received an invitation from the Honorable George Pirie, Ontario ’s Minister of Mines,

to join the MMIC for 2023. The committee aims to improve the business environment for the

mining sector in Ontario and to make Ontario the premier mining jurisdiction in the world.

Qualified person

This press release has been reviewed and approved by Mr. Jean-Sebastien David, P. geo, and

Qualified Person under NI 43 -101. Mr. David is NioBay’s President and Ch ief executive

officer (“CEO”).

About NioBay Metals Inc.

NioBay is a company focused on exploration, development and use of critical green metals

with an Environmentally, Sustainable, Governance, and Indigenous (ESGI) focus.

The Company holds a 100% interest in the James Bay Niobium Project located 45 km south of

Moosonee, in the Moose Cree Traditional Territory of the James Bay Lowlands in Ontario.

NioBay also holds a 72.5% interest in the Crevier N iobium and Tantalum project located in

Quebec and on the Nitassinan territory of the Pekuakamiulnatsh First Nation.

About Niobium

Niobium is a naturally occurring element. It is a readily available, reliable, soft 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 smarter and lower environmental

impacts, while also delivering other benefits like better performance, improved safety and

increased value.
