Vancouver, British Columbia – December 11, 2014 – NioCorp Developments Ltd. (“NioCorp” or the “Company”) [TSX-V: NB; OTCQX: NIOBF; and FSE: BR3] is pleased to announce additional assay results to complete its Phase II drilling program and advancement operations in Elk Creek, Nebraska.
The final analytical results have been received from drillholes NEC14-016 and NEC14-Met-03. NEC14-016 was drilled along a northeast to southwest trending section line through the resource, and NEC14-Met-03 was a vertical hole drilled through the approximate center of the defined Niobium resource. NEC14-Met-03 was drilled along with two other holes for the specific purpose of generating a bulk sample of the resource for pilot-scale testing, and was quartered and assayed due to its location. These results, in addition to drillholes NEC14-011, NEC14-012, NEC14-013, NEC14-014, and NEC14-015 continue to support niobium mineralization in the area of the defined resource and its continuation at depth, and together complete NioCorp’s Phase II drilling program.
The final analytical highlights for NEC14-016 and NEC14-Met-03 appear below: (Please note that due to the angle of the drilling and other factors, these results do not represent the true thickness of the Niobium resource.)

The collected core samples from drillhole NEC14-016 and NEC14-Met-03 were systematically processed and shipped for certified analytical analysis at Actlabs in Ancaster, Ontario to support NioCorp’s corporate objectives for the project.
“The final Phase II drilling results continue to be extremely encouraging and supportive of our project,” said Mark Smith, CEO of NioCorp. “I could not be more pleased with the overall high-grade assay results that have been delivered from both our Phase I and Phase II drilling program at our Elk Creek deposit,” continued Smith. “Third Phase drilling will be completed by mid-December 2014, and we are anxiously awaiting the upcoming analytical results.”
Review by Qualified Person and Quality Control:
Brad Ulry, B.Sc., P.Geo., Dahrouge Geological Consulting Ltd., a Qualified Person as defined by National Instrument 43-101, is responsible for the Elk Creek drilling operations and has read and approved the technical information contained in this news release.
Samples for both NEC14-016 and NEC14-Met-03 were continuously collected from the carbonatite’s upper contact at the base of the overlying limestone to the end of the drillhole. Samples were submitted to Activation Laboratories Ltd. (ActLabs) of Ancaster, Ontario. HQ diameter core (NEC14-016) was split into half-core samples and PQ diameter core (NEC14-MET-03) was split into quarter-core samples. Approximately 25% of the submitted core samples consist of quality control and quality assurance samples. Both drillholes ended in carbonatite.
About the Company:
NioCorp is developing the only primary niobium deposit known to be under development in the United States, and the highest grade undeveloped niobium deposit in North America, located near Elk Creek, Nebraska. The Company has completed an updated NI43-101 compliant resource report, available on SEDAR, reporting an Indicated resource of 28.2 Million Tonnes grading 0.63% Nb2O5, containing 177 Million Kg’s of Nb2O5, and an Inferred resource of 132.8 Million Tonnes grading 0.55% Nb2O5, containing 733.7 Million Kg’s of Nb2O5, (at a 0.3% Nb2O5 cutoff grade). Niobium is mainly used in the form of Ferro-Niobium to produce HSLA (High Strength, Low Alloy) steel, to produce lighter, stronger steel for use in automotive, structural and pipeline industries. The U.S. imports 100% of its niobium needs.
