Cautionary Note Regarding Forward-Looking Statements

This media release includes certain “forward-looking information” and “forward-looking

statements” (collectively “forward-looking statements”) within the meaning of applicable securities legislation, including

the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements include future-oriented financial information

Such information is intended to assist readers in understanding NOVAGOLD’s current expectations and plans relating to the future.

Such information may not be appropriate for other purposes. Forward-looking statements are frequently, but not always, identified by words

such as “expects”, “anticipates”, “believes”, “intends”, “estimates”, “potential”,

“possible”, and similar expressions, or statements that events, conditions, or results “will”, “may”,

“could”, “would” or “should” occur or be achieved. Forward-looking statements are necessarily based

on several opinions, estimates and assumptions that management of NOVAGOLD considered appropriate and reasonable as of the date such statements

are made, are subject to known and unknown risks, uncertainties, assumptions, and other factors that may cause the actual results, activity,

performance, or achievements to be materially different from those expressed or implied by such forward-looking statements. All statements,

other than statements of historical fact, included herein are forward-looking statements. These forward-looking statements include statements

to deliver on its strategy with the Donlin Gold project, increasing the value of the project. In addition, any statement that refers to

expectations, intentions, projections or other characterizations of future events or circumstances are forward-looking statements. Forward-looking

statements are not historical facts but instead represent the expectations of NOVAGOLD management’s estimates and projections regarding

future events or circumstances on the date the statements are made. Important factors that could cause actual results to differ materially

from expectations include the need to obtain additional permits and governmental approvals; the timing and likelihood of obtaining and

maintaining permits necessary to construct and operate; the need for additional financing to complete an updated Bankable Feasibility

or Canada; the need for continued cooperation between the owners of Donlin Gold LLC to advance the project; the need for cooperation of

government agencies and Native groups in the development and operation of properties; risks of construction and mining projects such as

accidents, equipment breakdowns, bad weather, non-compliance with environmental and permit requirements, unanticipated variation in geological

structures, ore grades or recovery rates; unexpected cost increases, which could include significant increases in estimated capital and

operating costs; fluctuations in metal prices and currency exchange rates; whether or when a positive construction decision will be made

regarding the Donlin Gold project; and other risks and uncertainties disclosed in NOVAGOLD’s most recent reports on Forms 10-K and
