NioCorp Developments Ltd. announced that it will analyze historic drilling core samples from the Elk Creek deposit in southeast Nebraska in order to compile sufficient data with the aim of publishing an updated Mineral Resource for the Elk Creek Critical Minerals Project (the "Project") that includes individual rare earth elements ("REEs") grades and tonnage that may exist in the deposit. The company is currently conducting extensive metallurgical testing to demonstrate, among other things, the potential extraction and recovery of REEs from the Project site, subject to receipt of necessary project funding. 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 planned product suite, which includes the critical minerals niobium, scandium, and titanium. The Company's REE initiative was launched in response to intense interest by governments and industrial consumers around the world for additional sources of rare earths beyond current suppliers.
