Montréal, Québec – TheNewswire - July 2, 2021 — Niocan Inc. (“Niocan” or the “Company”) (TSXV:NIO) (OTC:NIOCF) announces that it has amended its $2.345 million secured non-convertible debenture with Nio-Metals Holdings LLC (“Nio-Metals”) dated February 19, 2013 (the “Amended Secured Debenture”) by extending the maturity date from June 30, 2021 to December 30, 2021 (the “Amendment”). Except for the maturity date, the other material terms and conditions of the Amended Secured Debenture remain the same.

The Amendment was approved by all the members of the board of directors of Niocan, with the nominee of Nio-Metals abstaining given Nio-Metals’ interest in the matter. The Board considered the extension to be in the best interests of the Company given its financial position and current inability to repay the amounts owing under the Amended Secured Debenture.

Related Party Disclosure

Pursuant to Multilateral Instrument 61-101 -- Protection of Minority Security Holders in Special Transactions ("MI 61-101"), the Amended Secured Debenture constitutes a "related party transaction" as Nio-Metals (the “Related Party”) currently holds 49.4% of the issued and outstanding common shares of the Company.

The Company is exempt from the formal valuation requirement of MI 61-101 in connection with this amendment in reliance on section 5.5(b) of MI 61-101, as no securities of the Company are listed or quoted for trading on the Toronto Stock Exchange, Aequitas NEO Exchange Inc., the New York Stock Exchange, the American Stock Exchange, the NASDAQ Stock Market, or a stock exchange outside of Canada and the United States other than the Alternative Investment Market of the London Stock Exchange or the PLUS markets operated by PLUS Markets Group plc.

Additionally, the Company is exempt from obtaining minority shareholder approval in connection with the Amended Secured Debenture in reliance on section 5.7(1)(e) of MI 61-101, as the Company meets the requirements of the financial hardship exemption.

The Amendment enables the Company to continue its operations by deferring the repayment of the Amended Secured Debenture and the effect that such repayment would have on its financial position.  The Related Party, to the extent that it holds Niocan common shares and that the Amended Secured Debenture is not converted, will experience the same effects as other Niocan shareholders as a result of the Amendment. The Related Party will be entitled to receive interest and return of the principal amount of the Amended Secured Debenture in priority to the other Niocan shareholders.

Further details will be included in a material change report to be filed by the Company.  The material change report will not be filed at least 21 days prior to effective date of the Amendment due to the timing of the agreement to proceed with the Amendment in relation to the maturity date of the amended Secured Debenture previously in effect.
