(KLZA)-- NioCorp Developments Ltd. has announced the successful completion of a geotechnical drilling campaign at the Elk Creek Critical Minerals Project in southeast Nebraska, which was done in advance of the proposed site preparation, grading, heavy construction, and eventual foundation pours for the Elk Creek Project that are expected to commence once sufficient financing is obtained.

The campaign involved drilling 16 boreholes and 20 test pits across the one square mile Elk Creek Project site, analyzing soil samples, and generating data for engineering design firms that are continuing to finalize plans for the potential construction of the facility.

The drilling explored the "glacial till" geological layer, which is comprised of the first 30 meters or so of soil, clay, and sand that covers much of southeast Nebraska. This layer of sediment was deposited by repeated glaciation that occurred in the Pleistocene epoch that ended approximately 11,000 year ago.
