CENTENNIAL, Colo. (June 9, 2021) – NioCorp Developments Ltd. (“NioCorp” or the “Company“) (TSX:NB) (OTCQX:NIOBF) is pleased to announce the initiation of testing of Elk Creek Project (“Project”) ore using High-Pressure Grinding Rolls (“HPGR”) technology. HPGR technology is an energy efficient and low-emission alternative for reducing the size of the ore to enable the recovery of niobium, scandium, titanium, and potential rare earth products. The use of HPGR in the Project reinforces the Company’s commitment to the environment and designing a sustainable operation.
 NioCorp Initiates High Pressure Grinding Roll Testing of its Elk Creek Ore |
The testing is being conducted at the Natural Resources Research Institute (“NRRI”) of the University of Minnesota-Duluth, in partnership with Weir Minerals. During the testing, which is expected to take several weeks, approximately 3 tonnes of Elk Creek drill core will be reduced to the 1-millimeter size needed for hydrometallurgical testwork. The testwork is expected to provide key data that will be used to properly size the HPGR unit for the potential ore throughput at the Elk Creek Project, once project financing is secured and the project is operational.
The Company is currently evaluating next steps in its overall metallurgical testwork program, which will focus on optimizing and streamlining the existing processing flowsheet as well as establishing process routes for the potential recovery of rare earth products. The rare earth products that are of most interest to the Company at present are Neodymium-Praseodymium (“NdPr”) oxide, Terbium oxide and Dysprosium oxide. As previously announced, the Company has launched a review of the economic potential of expanding its currently planned product suite from the Project to also include rare earth products.
“After witnessing testing at NRRI, I was impressed with how the HPGR was able to handle the Elk Creek ore quickly and efficiently, with minimal noise and dust,” said Scott Honan, NioCorp COO. “We look forward to completing this phase of the testwork and moving on to look at further improvements to the existing flowsheet, including our new emphasis around the rare earths.”

About NioCorp
NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium. Also under consideration by the Company is the production of several magnetic rare earth products. Niobium is used to produce superalloys as well as High Strength, Low Alloy (“HSLA”) steel, which is a lighter, stronger steel used in automotive, structural, and pipeline applications. Scandium is a superalloy material that can be combined with Aluminum to make alloys with increased strength and improved corrosion resistance. Scandium is also a critical component of advanced solid oxide fuel cells. Titanium is used in various superalloys and is a key component of pigments used in paper, paint and plastics and is also used for aerospace applications, armor, and medical implants. Magnetic rare earths, such as Neodymium, Praseodymium, Terbium, and Dysprosium are critical to the making of Neodymium-Iron-Boron (“NdFeB”) magnets, which are used across a wide variety of defense and civilian applications.
