NioCorp's Elk Creek Critical Minerals Project to be Highlighted at the 2022 International Scandium Conference

CEO and Executive Chairman Mark A. Smith to Discuss NioCorp's Proposed Scandium Production in Southeast Nebraska and Prospective Scandium Markets

Conference Also Features Panel Discussion with NioCorp, Rio Tinto, Project Blue, and Traxys

CENTENNIAL, Colo., Oct. 10, 2022 /PRNewswire/ -- NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX:NB) (OTCQX:NIOBF) is pleased to announce that CEO and Executive Chairman Mark Smith will present on its Elk Creek Critical Minerals Project (the "Project") at the 2022 International Scandium Symposium, which will take place at the Westgate Resort Hotel in Las Vegas on Thursday, October 20, 2022.

The conference will feature presentations from NioCorp, Rio Tinto, and other prospective scandium producers from around the world.  Information on the conference can be seen here:  https://metalevents.com/events/international-scandium-symposium 

Mr. Smith's presentation, entitled "Nebraska Scandium:  American-Made and Climate-Smart," begins at 1 p.m. Eastern and will be followed by a question-and-answer period with the conference audience.  Presentations at the conference will not be broadcast live but are expected to be made available for video replay.

A panel discussion also will be held at 2:45 p.m. Eastern on October 20^th, featuring Mr. Smith; Wagner Oliveira, General Manager, Strategic Resource, Development and Mine Technical Services, Rio Tinto Iron and Titanium Canada; Nils Backeberg, Founder & Director, Project Blue, South Africa; and a representative from Traxys North America ("Traxys").

Subject to the receipt of necessary project financing and commencement of operations, the Project in southeast Nebraska positions the Company to emerge as a large prospective U.S. producer of scandium, with an estimated average production of 104 tonnes per year of Scandium over the Project's 38-year mine life.

NioCorp has executed a commercial sales agreement with Traxys for up to 120 tonnes of scandium trioxide over the first 10 years of operation of NioCorp's planned production, subject to the receipt of necessary project financing and commencement of operations at the Project.  The NioCorp—Traxys scandium contract is thought to be the largest single offtake agreement for scandium ever executed.

NioCorp is currently operating a demonstration plant in Quebec, Canada to test the technical feasibility of a simplified process for producing niobium, scandium, and titanium, as well as extracting and separating high-purity Neodymium-Praseodymium ("NdPr") Oxide, Dysprosium Oxide, and Terbium Oxide.

About NioCorp

NioCorp is developing a critical minerals project in Southeast Nebraska that will produce niobium, scandium, and titanium.  The Company also is evaluating the potential to produce several rare earths from the Project.  Niobium is used to produce specialty alloys 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 specialty metal 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 lightweight alloys 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.
