Elemental Analysis for Rare Earth Content of Historical NioCorp Elk Creek Deposit Commences

CENTENNIAL, Colo., Oct. 4, 2021 /PRNewswire/ — NioCorp Developments Ltd. («NioCorp» or the «Company«) (TSX: NB)(OTCQX: NIOBF) is pleased to announce that elemental analysis of historic drill core samples from the Elk Creek Superalloy Materials Project (the «Project«) to ascertain concentrations of rare earth elements («REEs«) and other elements has commenced at Activation Laboratories Ltd.’s («ActLab«) facility in Ancaster, Ontario.

ActLab will conduct assay analysis of more than 1,000 samples to determine the content of rare earths and other elements.  Results from this analysis, along with previous assays, are expected to compile data sufficient to support an update to the Project’s Mineral Resource to include individual rare earth elements grades and tonnage.

Updating the Project’s Mineral Resource is a significant step forward in the Company’s examination of the technical and economic feasibility of adding several REEs as byproducts to its current planned product suite, which includes the critical minerals niobium, scandium, and titanium. 

As previously reported, NioCorp is conducting extensive metallurgical testing at the pilot / demonstration plant level to quantify, among other things, the potential extraction and recovery of REEs from the Project site, subject to receipt of necessary project funding.  As part of this process, Salt Lake City-based L3 Process Development («L3«) is constructing and will operate a demonstration plant to process approximately 3,000 kilograms of crushed Project drill core in order to quantify the metallurgical performance of REEs and to address recommendations related to NioCorp’s 2019 Feasibility Study for the Project.

About NioCorp

NioCorp is developing a superalloy materials project in Southeast Nebraska that will produce Niobium, Scandium, and Titanium.  The Company also is evaluating the potential to produce several rare earth byproducts from the Project.  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.
