NioCorp Developments Ltd. Completes Convertible Security Funding Agreement for Institutional Investment of up to US $10.5 Million

CENTENNIAL, COLORADO--(Marketwired - Dec. 15, 2015) - NioCorp Developments Ltd. ("NioCorp" or the "Company") (TSX:NB)(OTCQX:NIOBF)(FRANKFURT:BR3) announces today that it has completed and signed a definitive convertible security funding agreement (the "Agreement") with an entity managed by The Lind Partners, a New York based asset management firm (together, "Lind"). An initial US$4.5 million will be funded pursuant to the issuance of an initial convertible security ("Convertible Security"), which is expected to occur on or around December 24, 2015 (the "First Tranche"). US$1.5 million of the First Tranche will be held in escrow pending certain conditions required to be satisfied by December 31, 2015. Lind can increase the funding under the Convertible Security by an additional US$1.0 million during its two-year term. Further, provided certain conditions are met, the Company will have the right to call an additional US$ 1.0 million under the funding agreement.

The Agreement also provides for the issuance of a second Convertible Security on mutual agreement of the Company and Lind, in which Lind would fund up to another US$6.0 million (the "Second Tranche"), which can also be increased by US$1.0 million.

Phillip Valliere, a Managing Director at The Lind Partners, commented: "We have been impressed with the NioCorp management team and the progress they have made on the Elk Creek niobium-scandium-titanium project. Lind's funding will help them complete the bankable feasibility study, the results of which will be key to unlocking the value of this project. We look forward to seeing the results of the BFS soon."

Mark A. Smith, NioCorp's Executive Chairman, stated: "We are very pleased to have finalized this funding facility with The Lind Partners, a highly regarded group of very successful institutional investors. This funding will move us further along toward completion of a bankable feasibility study for our Elk Creek project, which will then help to set the stage for us to acquire project financing and begin construction of our mine and processing facility in Nebraska."

Each Convertible Security has a two-year term from the date of issue and will incur a simple interest rate obligation of 10% on the amount funded that is prepaid and attributed to its face value upon the issuance of each Convertible Security. The Convertible Security is secured by the assets of the Company. The Company has agreed to pay a fee of US$135,000 for each of the First Tranche and Second Tranche (if any). Lind will be entitled to convert the Convertible Securities in monthly installments over the term, and the Conversion will be at a price per share of 85% of the five-day trailing volume-weighted average price ("VWAP") of the common shares (the "Shares") prior to the date that notice of conversion is provided by Lind. The Agreement contains restrictions on how much of the Convertible Securities may be converted in any particular month. NioCorp has the option to buy-back up to 70% of the Convertible Security in cash at any time for a nominal premium. Any Shares acquired upon conversion will not be tradable through the TSX until completion of a four-month-and-one-day hold from the time of funding the convertible note; however, the Company has covenanted to file a Short Form Prospectus to qualify the securities issuable under the first Convertible Security for trading. Lind will also be entitled to accelerate its conversion right to the full amount of the face value or demand repayment of the face value in cash upon a default and other designated events. To the extent that the full face value has not been converted at maturity, the balance of the face value is to be paid in cash at the end of the two-year term.

Further, Lind does not and has agreed not to short-sell the shares of the Company.

In addition, in respect of the First Tranche, the Company has agreed to issue 3.125 million warrants, exercisable into Shares for a period of three years at an exercise price of CAD$0.72 per Share. In respect of the Second Tranche (if any), the Company has agreed to issue a number of warrants under a formula based on the amount funded and the prevailing five-day VWAP prior to the date of issue. Any Second Tranche warrants will be exercisable into Shares for a period of three years, at an exercise price of 120% of the VWAP per Share for the five trading days before the Second Tranche closing.

The Convertible Security Funding Agreement and the issuance of securities thereunder, is subject to the acceptance of the TSX and to satisfaction of customary closing conditions.

Mark Smith, Executive Chairman and Director
