NioCorp to discuss plans to potentiall produce commercial grade RE oxides

NioCorp Developments will discuss at the 20 th Annual Rare Earth Conference in Washington, D.C. on October 15, 2024 its plans to potentially produce commercial grade magnetic rare earth oxides at its proposed Elk Creek, Nebraska Critical Minerals Project including the heavy rare earth oxides of dysprosium and terbium, and potentially recycle post-consumer RE permanent magnets. NioCorp also intends to explore the possibility of processing magnetic RE concentrates from multiple sources outside of China in order to increase its magnetic RE oxide production – including heavy REs such as dysprosium and terbium, beyond the Company’s current plans. NioCorp CEO and Executive Chairman Mark A. Smith will present at the Conference at 9:30 a.m. Eastern Time on October 15, 2024. NioCorp’s Elk Creek Project is designed to use a whole ore leach process to produce its targeted products, which include niobium, scandium, titanium and, potentially, magnetic RE oxides. Such a process could enable recycling of post-consumer neodymium-iron-boron permanent RE magnets back into separated RE oxides that can be used to make new NdFeB magnets. NioCorp’s planned hydrometallurgical process could also open up the possibility of accepting mixed RE concentrate from other mines and extracting larger amounts of magnetic REs than the Company is currently contemplating. The Elk Creek Project Mineral Resource contains the largest indicated terbium resource in the U.S., as well as the 2nd largest indicated neodymium-praseodymium and dysprosium resources in the U.S.
