Niocan Extends the Maturity Date of its $1.2 Million Secured Debenture

MONTREAL, QUEBEC--(Marketwired - Aug. 19, 2015) - Niocan Inc. ("Niocan" or the "Company") (TSX VENTURE:NIO) announces that it has amended its $1.2 million secured non-convertible debenture with Nio-Metals Holdings LLC ("Nio-Metals") dated February 19, 2013 to extend its maturity date from August 19, 2015 to September 30, 2015 (the "Amended Secured Debenture"). Except for the maturity date, the other material terms and conditions of the Amended Secured Debenture have remained the same. Discussions between Niocan and Nio-Metals regarding a financing to replace the Amended Secured Debenture at maturity are on-going.

Although the Amended Secured Debenture represents a "related party transaction" pursuant to National Instrument 61-101 respecting protection of minority security holders in special transactions ("NI 61-101") as Nio-Metals currently holds 43.4% of the issued and outstanding common shares of the Company, Niocan is not required to comply with the valuation and minority approval requirements as a result of exemptions which are available pursuant to NI 61-101. Moreover, given that the Amended Secured Debenture is non-convertible, it will have no effect on the direct or indirect voting interest that Nio-Metals holds in Niocan.
