Smith will present to investors on the Elk Creek Superalloy Materials Project (the «Project») during the H.C. Wainwright Spring Mining Virtual Conference on Tuesday, April 20, 2021.

Mr. Smith will provide an overview of the Project and its plans to produce the critical minerals niobium, scandium, and titanium once project financing is secured and the Project is operational.  Each of these elements is considered crucial to a variety of infrastructure, transportation, battery, and national defense technologies.  NioCorp is also currently reviewing the potential of adding commercial rare earth products to its product offering.

NioCorp’s presentation will begin at 2:00 p.m. Eastern on Tuesday, April 20, 2021 and will be conducted via Zoom video conferencing. The public may join the webcast at  In addition to being webcast live, Mr. Smith’s presentation also will be available for viewing at for 90 days following the live presentation.

Rare Earth Production is Now Also Being Considered by NioCorp

NioCorp is currently conducting a review of the economic potential of expanding its planned product suite of niobium, scandium, and titanium to also include rare earth products.  A recently completed geologic and metallurgical evaluation of all of the rare earth data associated with the Project shows that, of the 20,364 assay intervals in the Elk Creek database, 13,287 (65%) contain a complete suite of analytical data for all commercial rare earth elements.  Included within this dataset are 661 assays where the Total Rare Earth Oxide («TREO») assay results are greater than one percent.  More information on these results can be seen here.

NioCorp’s current plan to extract and purify niobium, scandium, and titanium from the Elk Creek ore involves putting these critical minerals into solution, which also solubilizes the rare earth elements.  NioCorp is now considering the economic potential for recovering the solubilized rare earths into commercial rare earth products.

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce the critical minerals niobium, scandium, and titanium. 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.  NioCorp is also evaluating the rare earth potential of its Nb/Ti/Sc Resource.
