Niobium Scandium Magnetic Rare Earths NioCorp Critical Mineral Security Value Proposition: Transition to Net Zero Emissions is Driving Demand Growth for the Critical Minerals at the Focus of NioCorp¹ [] Shovel-ready¹ pure-play critical minerals project with the highest-grade Niobium resource in North America and the 2nd largest indicated rare earth resource in the U.S.² Positioned to become a major U.S. miner / producer of Niobium, which is forecast to see strong demand growth via rapid-charging solid state Li-Ion batteries.³ Large prospective U.S. producer of Scandium with a Scandium Mineral Reserve supported by a feasibility study. Scandium has large latent demand in the commercial aviation and automotive sectors.4 NioCorp is conducting technical and economic analyses5 on the potential addition to its planned product suite of several magnetic rare earth oxides, which are forecast to experience large supply shortages because of sharply rising demand.6 Project is strongly focused on environmental, social, and governance values and is already aligned with the Equator Principles ESG Framework. EQUATOR PRINCIPLES 1 Subject to receipt of necessary project financing and commencement of operations at the Elk Creek Project. 2 Indicated mineral resource, based on data from the "Critical Mineral Resources of the United States-Economic and Environmental Geology and Prospects for Future Supply," U.S. Geological Survey, 2017, and from company-issued reports. 3 Source: CBMM. 4 "Scandium: A Market Assessment," ONG Commodities, 2019. 5 As no economic analysis has been completed on the rare earth mineral resource comprising the Project, further studies are required before determining whether extraction of rare earth elements can be reasonably justified and economically viable after taking account relevant factors. 6 "Rare Earth Magnet Market Outlook to 2035," Adamas Intelligence, 2022. 8
