Slide 2 — CAUTIONARY STATEMENTS

CAUTIONARY STATEMENTS REGARDING FORWARD-LOOKING STATEMENTS This presentation 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 or financial outlook within the meaning of securities laws, including information regarding the benefits of the announced transaction with Paulson, NOVAGOLD’s anticipated expenditures and anticipated plans for the new partnership and Donlin following the completion of the transaction, statements regarding the permitting, potential development, exploration, construction and operation of Donlin Gold and statements relating to NOVAGOLD’s future operating and financial performance and production estimates. 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”, “continue”, “ongoing”, “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 regarding the anticipated consummation and timing of the transaction; the expected timing of closing of the transaction; the satisfaction of the conditions precedent; the anticipated benefits of the transaction; timing of certain judicial and/or administrative decisions; the timing and potential for commencing a new feasibility study on the Donlin Gold project; the results of future feasibility studies; ongoing support provided to key stakeholders including Native Corporation partners; Donlin Gold’s continued support for the state and federal permitting process; sufficiency of working capital; the potential development and construction of the Donlin Gold project; the timing and ability for the Donlin Gold project to hit critical milestones; the ability for the Donlin Gold project to hit the anticipated projections; the sufficiency of funds to continue to advance development of Donlin Gold, including to a construction decision; perceived merit of properties; mineral reserve and mineral resource estimates; Donlin Gold’s ability to secure the permits needed to construct and operate the Donlin Gold project in a timely manner, if at all; legal challenges to Donlin Gold’s existing permits and the timing of decisions in those challenges; whether the Donlin Gold LLC board will continue to advance the Donlin Gold project safely, socially responsibly and to sustainably generate value for our stakeholders; continued cooperation between the owners of Donlin Gold LLC to advance the project; the Company’s ability to deliver on its strategy with the Donlin Gold project, increasing shareholder and stakeholder wealth; the success of the strategic mine plan for the Donlin Gold project; the success of the Donlin Gold community relations plan; the outcome of exploration drilling at the Donlin Gold project and the timing thereof; and the completion of test work and modeling and the timing thereof. In addition, any statements that refer 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 failure to satisfy or waive the closing conditions to the transaction; 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 feasibility study and to explore and develop properties; availability of financing in the debt and capital markets; disease pandemics; uncertainties involved in the interpretation of drill results and geological tests and the estimation of reserves and resources; changes in mineral production performance, exploitation and exploration successes; changes in national and local government legislation, taxation, controls or regulations and/or changes in the administration of laws, policies and practices, expropriation or nationalization of property and political or economic developments in the United States or Canada; development and eventual construction of the Donlin Gold property; 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, disease pandemics, 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 10-Q, particularly the “Risk Factors” sections of those reports and other documents filed by NOVAGOLD with applicable securities regulatory authorities from time to time. Copies of these filings may be obtained by visiting NOVAGOLD’s website at www.novagold.com, or the SEC’s website at www.sec.gov, or on SEDAR+ at www.sedarplus.ca. The forward- looking statements contained herein reflect the beliefs, opinions and projections of NOVAGOLD on the date the statements are made. NOVAGOLD assumes no obligation to update the forward-looking statements of beliefs, opinions, projections, or other factors, should they change, except as required by law. Forward-looking statements contained in this presentation are based on a number of material assumptions, including but not limited to the following, which could prove to be significantly incorrect: our ability to achieve production at any of our mineral exploration and development properties; estimated capital costs, operating costs, production and economic returns; estimated metal pricing, metallurgy, mineability, marketability and operating and capital costs, together with other assumptions underlying our resource and reserve estimates; our expected ability to develop adequate infrastructure and that the cost of doing so will be reasonable; assumptions that all necessary permits and governmental approvals will be obtained and the timing of such approvals; assumptions made in the interpretation of drill results, the geology, grade and continuity of our mineral deposits; our expectations regarding demand for equipment, skilled labor and services needed for exploration and development of mineral properties; and that our activities will not be adversely disrupted or impeded by development, operating or regulatory risks. This presentation shall not constitute an offer to sell, nor the solicitation of an offer to purchase referenced herein. CAUTIONARY NOTE CONCERNING RESERVE & RESOURCE ESTIMATES This presentation uses the terms “mineral resources”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. Mineral resources that are not mineral reserves do not have demonstrated economic viability. You should not assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. Further, inferred mineral resources have a lower level of confidence than that applying to indicated mineral resources and may not be converted to mineral reserves. The SEC’s current mining disclosure rules (“S-K 1300”) are more closely aligned with current industry and global regulatory practices and standards, including National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. While S-K 1300 is more closely aligned with NI 43-101 than the prior SEC mining disclosure rules, there are some differences. Notably, unlike NI 43-101, S-K 1300 requires that resources be disclosed exclusive of mineral reserves, and that mineral resources and reserves be disclosed on the basis of our interest in them. The resource and reserve estimates included in the 2021 Technical Report (as defined below) and the S-K 1300 Technical Report Summary (as defined below) have been prepared in accordance with NI 43-101 and S-K 1300, respectively. Paul Chilson, P.E., who is the Manager, Mine Engineering for NOVAGOLD and a “qualified person” under NI 43-101 and S-K 1300, has approved the scientific and technical information contained in this presentation.

Wood Canada Limited Most Recent Disclosure “NI 43-101 Technical Report on the Donlin Gold Project, Alaska, USA” (“2021 Technical Report”) prepared by Wood Canada Limited (“Wood”), effective June 1, 2021. “S-K 1300 Technical Report Summary on the Donlin Gold Project, Alaska USA” (“S-K 1300 Technical Report Summary”) prepared by Wood, dated November 30, 2021. “The announcement of our new partner, Paulson Advisers, marks the watershed moment in our company’s ambition to unlock conscientiously the full value of Donlin Gold. For such a prescient and illustrious gold investor as John Paulson to share our belief that Donlin Gold constitutes one of the best and most jurisdictionally attractive gold development projects in the world — and indeed worthy of such an extraordinary investment — is truly catalytic for NOVAGOLD.” Dr. Thomas S.

Slide 8 — ABOUT PAULSON

TRANSACTION OVERVIEW ABOUT PAULSON Select Gold Mining Investments ▪Founded by John Paulson, it’s a private global investment advisory firm headquartered in Palm Beach, Florida ▪Proven talent in seeing the “Big Trade” and identifying the right vehicles with which to leverage those convictions ▪One of NOVAGOLD’s longest-standing and most engaged investors – as well as second largest shareholder (27,238,061 shares) ▪A successful track record of investments in the gold space – ranging from gold mine developers to major gold producers 8 “Donlin Gold is one of the most attractive undeveloped gold projects in the world. With 39 million ounces of gold at double the industry average grade, and an optimal location in the prime jurisdiction of Alaska — already the second largest gold-producing state in the United States — we believe that the project could create value for decades to come. Enjoying excellent social license and formidable exploration upside potential to significantly expand its resources and production profile, Donlin Gold constitutes a superb opportunity for us to gain leverage to gold in the United States. Together with Donlin Gold’s partners, Calista and TKC, we are dedicated to responsibly advance the Donlin Gold project.” John Paulson April 22, 2025 NOVAGOLD | 2025 Canaccord Global Metals & Mining Conference

NOVAGOLD | 2025 Canaccord Global Metals & Mining Conference ENDNOTES APPENDIX SLIDE 6 – NOVAGOLD and Paulson Advisers to Acquire 50% of Donlin Gold from Barrick Gold in $1 Billion Transaction 1. Paulson, Electrum and Kopernik received five-year warrants to purchase an aggregate of 25.5 million common shares at US$3.00 per share. SLIDE 7 – Donlin Gold is simply unique in the global gold space in its rare combination of key attributes: 1. Anticipated average annual gold production during full life of mine if put into production as contemplated in the 2021 Technical Report and the S-K 1300 Technical Report Summary. See “Cautionary note concerning Reserve & Resource Estimates” and “Mineral Reserves & Mineral Resources” tables on slides 2, 26 and 27. 2. Represents 100% of measured and indicated resources, inclusive of mineral reserves, of which 50% is attributable to NOVAGOLD. Donlin Gold is not in production and a construction decision has not been made. For more information see “Cautionary Note Concerning Reserve and Resource Estimates” and “Mineral Reserves & Mineral Resources” tables on slides 2, 26 and 27. 3. Represents average grade of measured and indicated mineral resources, inclusive of mineral reserves. See “Cautionary Note Concerning Reserve and Resource Estimates” and “Mineral Reserves & Mineral Resources” tables on slides 2, 26 and 27. 4. Per Mining Journal intelligence – World Risk Report 2024 Alaska received an AA rating, ranks number 13th globally on the Investment Risk index. 5. Under appeal. Appeals challenging permits in State courts have been unsuccessful to date and the Biden Administration fully defended the Federal permitting decisions. In the Federal litigation challenging the Donlin Gold Joint Record of Decision, including the 404 permit and ROW for portions of the pipeline crossing federal lands, the Court issued a decision on September 30, 2024. The decision upheld the federal agencies’ analysis on two of the three issues raised in the litigation, but agreed with plaintiffs that the federal agencies took too narrow a view in analyzing the impact of a theoretical release from the tailings storage facility. The Federal District Court requested supplemental briefing on the appropriate remedy for addressing this issue. On October 7, 2024, the plaintiffs filed a request for reconsideration on one of the issues on which the Federal District Court had ruled against the plaintiffs and, at DOJ’s request, the Federal District Court suspended the schedule for briefing on the appropriate remedy until after the Federal District Court ruled on plaintiffs’ motion for reconsideration. On December 23, 2024, the Federal District Court denied plaintiffs’ request for reconsideration. Remedy briefing was completed in March 2025 and oral arguments on remedy were held on May 9, 2025. SLIDE 9 – Extraordinary leverage to gold in a jurisdiction where one can keep the fruits of that leverage 1. Donlin Gold estimates as per the 2021 Technical Report and the S-K 1300 Technical Report Summary, except as noted below. All dollar figures are in USD, represent 100% of the project of which NOVAGOLD’s share is 50%, and reflect after-tax net present value (at 0% and 5% discount rates) of the Donlin Gold project using the reference date of start of Year -06 as the first year of discounting. Estimated owner’s initial capital project development costs of approximately $348M to be spent prior to the reference date are treated as sunk costs. At a 5% discount rate, the net present value is: ($1,832M) @ $1,000 gold; $202M @ $1,200 gold; $1,161M @ $1,300 gold; $3,040M @ $1,500 gold; $4,887M @ $1,700 gold; $7,229M @ $2,000 gold; and $11,199M @ $2,500 gold. Gold price sensitivity was evaluated to a maximum of $2,500 per troy ounce as part of the 2021 Technical Report and the S-K 1300 Technical Report Summary. The project requires a gold price of approximately $930 per ounce to break even on an undiscounted cash flow basis and a gold price of approximately $1,180 per ounce to break even on a 5% discounted basis. SLIDE 10 – Strong institutional shareholder base 1. Shareholder positions are based on the latest 13-D, 13-F, 13-G or Form 4 filings. 2. Common shares issued and outstanding, options, PSUs, and DSUs effective March 26, 2025. See SEC Form 10- Qfiling dated April 1, 2025 for additional information. 3. This percentage reflects shareholder positions based on the latest publicly available filings and does not account for shares issued to shareholders in NOVAGOLD’s recent public offering dated May 9, 2025, or warrants issued to shareholders as part of the backstop agreement dated April 22, 2025. SLIDE 14 – Positioned to become a million-ounce gold producer 1. Average of comparison group data of 10 projects shown on slide 14 based on large (3Moz proven and probable mineral reserves cut off), North/South American gold-focused development projects with >75% projected revenues from gold, as per latest company public filings and websites as of May 2025. 2. Anticipated average annual gold production during full life of mine if put into production as contemplated in the 2021 Technical Report and the S-K 1300 Technical Report Summary. See “Cautionary note concerning Reserve & Resource Estimates” and “Mineral Reserves & Mineral Resources” tables on slides 2, 26 and 27. SLIDE 15 – Size Matters: exceptional opportunity for value creation for decades to come 1. Donlin Gold data as per the 2021 Technical Report and the S-K 1300 Technical Report Summary. SLIDE 16 – Grade is king: Donlin Gold has more than double the global average gold grade 1. Represents 100% of measured and indicated resources, inclusive of mineral reserves, of which 50% is attributable to NOVAGOLD. Donlin Gold is not in production and a construction decision has not been made. For more information see “Cautionary Note Concerning Reserve and Resource Estimates” and “Mineral Reserves & Mineral Resources” tables on slides 2, 26 and 27. 2.

Mineral Reserves are reported within the pre-feasibility pit designs, and supported by a mine schedule, featuring variable throughput rates, stockpiling and cut-off optimization. The pit designs are contained within an optimized pit shell based on the following economic and technical parameters: Metal price for gold of $1,200/oz; reference mining cost of $2.16/t incremented $0.0033/t/m with depth from the 220 m elevation (equates to an average mining cost of $2.64/t), fixed processing cost $13.78/t processed; sustaining capital of $1.54/t processed; general and administrative cost of $3.66/t processed; stockpile rehandle costs of $0.24/t processed assuming that 45% of mill feed is rehandled; variable metallurgical recoveries by rock type, ranging from 86.7% in shale to 94.2% in intrusive rocks in the Akivik domain; refining and freight charges of $1.21/oz gold; royalty considerations of 4.5% NSR and $0.50/t processed; and variable pit slope angles, ranging from 23° to 43°. Mineral Reserves are reported using an optimized block value (BV) based on the following equation: BV = Au grade * Recovery * $1,200/oz – royalties & refining costs – process operating costs – G&A cost reported in $/t. Assuming an average gold recovery of 89.5% the marginal gold cut-off grade would be approximately 0.57 g/t, or the gold grade that would equate to a $0.001 BV cut-off at these same values. The life-of-mine (LOM) strip ratio is 5.48:1. The assumed LOM throughput rate is 53,500 t/d. The technical parameters referenced herein are based on the specifications utilized in the Donlin Creek Gold Project Alaska, USA, NI 43-101 Technical Report on Second Updated Feasibility, effective November 18, 2011 (as amended January 20, 2012). The economic parameters are derived from the NI 43-101 Technical Report on the Donlin Gold Project, Alaska, USA, effective June 1, 2021, and the S-K 1300 Technical Report Summary on the Donlin Gold Project, Alaska, USA, November 30, 2021. 2. Except as noted, Mineral Resources are inclusive of Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Inferred Resources are in addition to Measured and Indicated Resources. Inferred Resources have great uncertainty as to their existence and whether they can be mined legally or economically. The cut-off date for the sample database used in the Mineral Resource estimate is 1 November 2009. However, more recent drilling data were used to validate the resource model as remaining current. Mineral Resources are constrained within a conceptual Measured, Indicated and Inferred optimized pit shell using the following assumptions: gold price of $1,200/oz; variable process cost based on 2.1874 * (sulphur grade) + 10.6485; administration cost of $2.29/t; refining, freight & marketing (selling costs) of $1.85/oz recovered; stockpile rehandle costs of $0.20/t processed assuming that 45% of mill feed is rehandled; variable royalty rate, based on royalty of 4.5% * (Au price – selling cost); and a variable metallurgical recovery depending on the host rock type ranging from 86 to 94%. Assuming an average recovery of 89.5% and average S% grade of 1.07, the marginal gold cut-off grade is 0.47 g/t. These technical and economic parameters are those that were used in the Donlin Creek Gold Project Alaska, USA, NI 43-101 Technical Report on Second Updated Feasibility Study, effective November 18, 2011 (as amended January 20, 2012) to establish reasonable prospects of eventual economic extraction. Based on the QP’s review of the estimate, there would be no material change to the Mineral Resources if the gold price were updated to $1,500/oz and other economic parameters were updated to the 2020 parameters used in the Mineral Reserve estimate. As a result, the Mineral Reserve and Mineral Resource estimates shown above remain unchanged from the 2011 estimates contained in the prior technical report. See “Cautionary Note Concerning Reserve & Resource Estimates” on slide 2.
