Niobay Metals improves recovery and concentrate for production of niobium

batteries from its James Bay Niobium Project.

Result Highlights:

• Recoveries 40% higher than similar projects

• The concentration of Nb2O5 is 10% higher than its peers

• The low silica content and higher Nb2O5 concentration should lead to a significant

reduction in acid consumption for the production of battery-grade Niobium

• The final results for the production of battery-grade Niobium oxide to come

Montreal, Quebec, October 14, 2021 – NioBay Metals Inc. ("NioBay" or the "Company") (TSX-V: NBY)

(OTCQB: NBYCF), a company focused on exploration, development and use of critical green metals

with an Environmentally, Sustainable, Governance, and Indigenous (ESGI) focus, is pleased to provide

the first results from its metallurgical program. The program is design ed to achieve b attery grade

Niobium oxide to be used as anode material in fast charging lithium battery technology.

As published on April 6, 2021, the Company announced the beginning of a series of metallurgical

testing related to the production of battery-grade Niobium from its James Bay Niobium Project

(the “James Bay Project”) . This first phase of testing, performed by SGS Lakefield Inc, consisted of

producing a Niobium concentrate, similar to the previous tests done on the James Bay Project’s ore.

The results demonstrated a 3% improvement from the Company’s market-leading Preliminary

Economic Assessment (“PEA”) recovery, reaching up to 81.3% while producing a Niobium concentrate

of 61.7%. In addition, the lack of deleterious material and low silicate content should translate in a

significant reduction in acid consumption for the battery -grade Niobium oxide production. The first

phase of metallurgical testing also contributed to optimizing the parameters and flowsheet design.

Average Min Max

Nb2O5 Grade (%) 59.8 56.8 61.7

Recovery (%) 74.7 67.9 81.3

The higher concentration, recovery and purity of the James Bay Project provides the best potential

low-cost Niobium project in North America.

Word from the CEO

"We are very excited by the 3% metal recovery improvement over the PEA result. Th ese results

reinforce the strong economic potential of the James Bay Niobium Project and separate it as the best

alternative low-cost source of battery-grade Niobium oxide outside China. We are confident that the

ongoing testing will future advance the production of a green metal that will support global

decarbonization", stated Jean-Sebastien David, the Company’s new President and CEO.

Niobium Battery Technology

The second phase of the ongoing metallurgical program will focus on the production of niobium

battery grade and consist of a hydrometallurgical treatment to purify the concentrate to +99% Nb2O5

(battery-grade Niobium oxide). Results are expected in the upcoming months.

Pilot plant

Following these metallurgical results, the team has fast tracked the planning for the construction of a

pilot plant to accelerate the potential production of battery -grade material for a testing partner. In

addition, th is plant will assist in the plant conception for the upcoming pre-feasibility/feasibility

studies.

Grant of Options

The Board of Directors granted to the new CEO of the company an option to acquire 150 000 common

Nitassinan territory of the Pekuakamiulnatsh First Nation and a 4 8% direct participation in mineral

titles situated in the Chibougamau region, Quebec, under a joint venture agreement with SOQUEM.

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.
