James Bay Niobium’s History

11

Discovered in 1966§ 14,000 meters of drilling at an average depth of 170 meters in 85 holes.§ Historical estimate of 56M t @ 0.52% Nb2O5.

§ Open at depth (below 275m).§ Exploration shaft (~40m ) & a 75m cross-cut.§ 225 t extracted for metallurgical testing (pilot plant).

Lakefield Research carried out metallurgical tests§ Overall recovery of 78%, very low impurities, and high grade concentrate.

Feasibility study completed by Bechtel Canada in 1969

Access to all historical technical data and drill cores.Note: NioBay Metals has not yet undertaken the work necessary to verify or classify the historical estimates. Economic studies completed in the1960s does not mean the James Bay Niobium deposit would be found to be economic today. NioBay Metals is not treating the historical results as acurrent mineral resource nor as having been verified by a qualified person.

James Bay Niobium Resource

12

§ A Mineral Resource Estimate 2018 (43-101) was published by RPA.

§ Mineralization is open at depth (> 275m).§ A crown pillar is excluded from the resource (abt 6 Mt).§ 30m of overburden.§ High potential to increase resources.
