NioCorp To Hold Special Meeting of Shareholders on May 17, 2016 Regarding Incentive for Early Exercise of Warrants

CENTENNIAL, Colo., April 04, 2016 -- NioCorp Developments Ltd. (“NioCorp” or the “Company”) (TSX:NB) (OTCQX:NIOBF) (FSE:BR3) announces that it will conduct a Special Meeting of Shareholders on Tuesday May 17, 2016 at 10 a.m. Mountain Time.

NioCorp proposes to implement an early warrant exercise program (the “Program”) designed to encourage the early exercise of (unlisted) share purchase warrants exercisable at $0.65 that otherwise expire on November 10, 2016 (the “Warrants”).  The Program and commencement of the Program is subject to disinterested shareholder approval (excluding any votes held by shareholders that are also holders of the Warrants) which will be sought at the Special Meeting, and final Toronto Stock Exchange (“TSX”) approval.

The inducement to exercise early will be provided in the form of incentive shares of the Company (the “Incentive Shares”).  The ultimate determination as to the total number of Incentive Shares (or fraction of Incentive Share per Warrant) to be issued on exercise of the Warrants during the 30 day incentive period will be made based on the Market Price of the Company’s common shares on the TSX immediately before the start of incentive period.

NioCorp has engaged Mackie Research Capital Corporation to provide services in connection with the Program, including financial advice and analysis and solicitation of the holders of the Warrants to participate in the Program.
