NOTICE-AND-ACCESS NOTIFICATION

Important Notice Regarding the Availability of Proxy Materials for the Annual General Meeting of Shareholders to Be Held on December 2, 2021

Dear Shareholder:

You are receiving this Notice-and-Access Notification because NioCorp Developments Ltd. (the "Company") has decided to use the notice-and-access model for delivery of meeting materials for its 2021 Annual General Meeting (the "Meeting") to its registered shareholders and Canadian and United States beneficial shareholders. This Notice-and-Access Notification regarding the Meeting is prepared pursuant to the notice-and-access rules that came into effect on February 11, 2013 under National Instrument 54-101 - Communication with Beneficial Owners of Securities of a Reporting Issuer, National Instrument 51-102 - Continuous Disclosure Obligations and Rule 14a-16 under the United States Securities Exchange Act of 1934, as amended. Under notice-and-access, instead of a paper copy of the Notice of Meeting, Management Information and Proxy Circular (the "Information Circular"), 2021 Annual Report and form of proxy (the “Proxy” and, together with the Notice of Meeting, the Information Circular and the 2021 Annual Report, the "Meeting Materials"), shareholders receive this Notice-and-Access Notification with information on how they may access such materials electronically. The use of this alternative means of delivery is more environmentally responsible as it will help reduce paper use and also will reduce the cost of printing and mailing materials to shareholders. This communication is not a form for voting and presents only an overview of the more complete information in the Meeting Materials, which contain important information and can be accessed online as provided below.

The Company has elected not to use the procedure known as "stratification" in relation to its use of the notice-and-access rules. Stratification occurs when a reporting issuer using the notice-and-access rules provides a paper copy of proxy-related materials to some, but not all, of its shareholders.

MEETING DATE AND LOCATION
