NioCorp Announces Additional Assay Results from Phase II Drilling Program in Elk Creek, Nebraska

NioCorp Developments Ltd. 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.)

  • 83 m (830 - 913 m) at 1.00 % Nb₂O₅

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."
