VANCOUVER, British Columbia, Oct. 01, 2025 (GLOBE NEWSWIRE) -- NOVAGOLD RESOURCES INC. ("NOVAGOLD" or the "Company") ((NYSE American, TSX:NG) today filed its 2025 third quarter report and provided an update on its Tier One³ gold development project, Donlin Gold, which is owned 60 percent by NOVAGOLD and 40 percent by funds managed by Paulson.

Details of the financial results for the quarter ended August 31, 2025 are presented in the consolidated financial statements and quarterly report on Form 10-Q filed on October 1, 2025, that is available on the Company's website at www.novagold.com, on SEDAR+ at www.sedarplus.ca, and on EDGAR at www.sec.gov. All amounts are in U.S. dollars unless otherwise stated.

As detailed in the above-mentioned filings, NOVAGOLD held approximately $125 million in cash and term deposits as of August 31, 2025, and reported net third quarter cash expenditures of $9 million — reflecting $8.1 million to fund NOVAGOLD's share of the Donlin Gold project and $0.9 million in corporate general and administrative costs. This excludes consideration and closing costs paid to increase NOVAGOLD's interest in Donlin Gold LLC to 60 percent and proceeds raised following the exercise of the public offering overallotment option on June 5, 2025.

As NOVAGOLD is a development-stage company with no production, the Company reported earnings of ($15.6) million and earnings per share of ($0.04) for the third quarter of 2025. NOVAGOLD's results for the three and nine months ended August 31, 2025 reflect higher expenditures at Donlin Gold due to the 2025 field program and ramp-up of activities to commence the BFS, while remaining in line with our 2025 guidance, as adjusted to reflect a 60 percent Donlin Gold funding obligation commencing June 3, 2025, when NOVAGOLD's interest in Donlin Gold increased to 60 percent.

Additional Achievements at Donlin Gold in the Third Quarter 2025 Comprised:

Shortly after quarter end, completed the 18,454-meter 2025 drill program including grid drilling for future mine planning; in-pit exploration drilling focused on enhancing geological modelling and supporting anticipated resource conversion; and geotechnical drilling in pit and for further investigation of material sites for construction of the access road.
A dedicated team of more than 80 personnel and contractors supported the increased level of activity. Recruitment for different roles at Donlin Gold is ongoing as we ramp up efforts toward a BFS.
Hosted project site tours with investors and analysts, followed by the owners' tour which included meetings with principal stakeholders, including government agencies, engineering firms, and logistics providers that have the capacity and experience to provide support for key pieces of project infrastructure to advance Donlin Gold to a BFS and beyond.
Community engagement and environmental initiatives:
- Representatives from Donlin Gold, NOVAGOLD, Paulson, and The Electrum Group LLC met with Calista Corporation ("Calista"), The Kuskokwim Corporation (TKC), and other Yukon-Kuskokwim (Y-K) region stakeholders.
- Hosted the Crooked Creek Traditional Council for a Donlin Gold project site visit, along with a separate site tour for State of Alaska Representatives.
- Finalized an additional Shared Values Statement (SVS) for a total of 19 with communities in the Y-K region near the project.
- Advanced environmental channel restoration efforts at Snow Gulch, a tributary of Donlin Creek historically mined for placer gold, to restore natural habitat conditions in support of aquatic life.

President's Message

A new era for Donlin Gold, anticipated to become America's largest single gold mine

Following a pivotal sequence for NOVAGOLD, the third quarter of 2025 was marked by multiple notable milestones that have utterly transformed the Company and the Donlin Gold project. These achievements began on June 3 with the completion by NOVAGOLD and Paulson of the $1 billion acquisition of Barrick Mining's 50 percent interest in the project. The definition of a "game changer", NOVAGOLD gained a new and aligned partner while securing an additional 10 percent ownership in this Tier 1 asset for $200 million — increasing its stake in Donlin Gold LLC from 50 percent to 60 percent.

Not surprisingly, the share price has performed strongly — multiplying several-fold off the lows seen earlier this year. As evidenced by the market's reception, it has not been lost on investors that this watershed moment represents in and of itself the single most significant development for the Company's stakeholders in over a decade. As the market understands that NOVAGOLD and Paulson have put Donlin Gold back on track toward a construction decision for what is anticipated to be America's largest gold mine, we believe that this first phase of our upward revaluation has the potential to segue into a similarly gratifying second phase. That is certainly our ambition, as this generational project makes up for lost time — all the while enjoying the fact that this accelerating momentum is taking place amidst a historic bull market.

Subsequent to this acquisition, NOVAGOLD announced the full exercise and closing of the underwriters' option to purchase an additional 7,177,500 common shares, corresponding to $26 million in net proceeds, at $3.75 per share. As a result, the total number of shares sold in the public offering increased to 55,027,500, generating approximately $195.2 million in net proceeds after deducting underwriting discounts and offering expenses, with an additional $64.4 million generated by a private placement which closed in the second quarter. With net proceeds totaling some $260 million, the Company was able to fund its share of the acquisition and ended the third quarter with a robust treasury of approximately $125 million in cash and term deposits to support the project's future steps up the value chain.
The acquisition of our increased 10 percent stake and the arrival of an aligned co-owner, not to mention the excellent reception of those developments in the marketplace, have put a spotlight on Donlin Gold — and for very good reasons. The project enjoys a unique combination of attributes that are arguably unmatched in the mining world: scale, open-pit high grade, production profile and decades-long mine life, low operating cost estimates, exploration upside⁴, and attractive jurisdictional safety⁵. It defines our mantra that Donlin Gold provides the maximum leverage to gold…in a jurisdiction that will allow one to keep the fruits of that leverage. In an era characterized by sheer scarcity of great gold assets, a generational project like Donlin Gold — itself expected to become the largest single gold producing mine in the United States — constitutes for us the "Holy Grail" of the industry.
We believe such an assessment may well be enhanced further by a district-wide exploration program currently being designed to expand resources and search for new discoveries.

At present estimates of scale and grade, 39 million ounces in Measured and Indicated Mineral Resources, 541 million tonnes at an average grade of 2.24 grams per tonne⁶ (inclusive of Mineral Reserves) — more than twice the industry average⁷ — Donlin Gold already stands in a rarefied league. But one must remember that this is not the whole story. That particular resource represents only three kilometers of an already known mineralized belt of eight kilometers. We believe resource expansion is possible, particularly because that eight-kilometer belt itself represents less than five percent of Donlin Gold's total land package. And with the land substantially unexplored to date, the next Donlin may well be at Donlin. In partnership with Paulson, the Company plans to empower among the industry's most dynamic and experienced exploration geologists to lay out a comprehensive agenda to advance our thesis.

New Partnership with Paulson and Strengthened Engagement to Drive Donlin Gold's Growth

During the third quarter, the Company conducted two Donlin Gold site tours. In June, market analysts and NOVAGOLD shareholders traveled to the project site for a visit that included meetings with Calista, project staff, and stakeholders. In July, a collaborative visit took place in Alaska involving the Donlin Gold team, senior representatives from NOVAGOLD and Paulson, including two prominent NOVAGOLD shareholders — Mr. John Paulson and Dr. Thomas S. Kaplan. During the visit, participants met with Calista and TKC in Anchorage and in the Y-K region, respectively, which provided an excellent opportunity for NOVAGOLD's new partner in Donlin Gold, Paulson, to interact with and gain direct insight from local stakeholders as well as discuss the path forward. The group travelled by boat on the Y-K river to engage with locals and develop an even greater appreciation for the region and its customs.

As part of the tour with Paulson, meetings were held with leading Alaska government representatives —including Governor Mike Dunleavy, Department of Natural Resources Commissioner John Boyle, and former Department of Revenue Commissioner Adam Crum among others — to formally introduce the new Donlin Gold ownership and to discuss shared priorities between the State of Alaska, the second-largest gold-producing state in the U.S., and the project. Alaska offers strong opportunities for responsible development of employment-generating projects like Donlin Gold. In addition, a series of discussions with natural gas pipeline developers explored potential opportunities to deliver natural gas to Southcentral Alaska, which could also benefit Donlin Gold and its stakeholders.

Following the July Alaska visit by senior representatives from NOVAGOLD and Paulson, a re-examination of the 2025 Donlin Gold budget was completed by the current owners of the project. Some activities that were originally planned for 2025 were redirected to support BFS work, with no material impact expected on Donlin Gold's previously announced $43 million budgeted expenditures for 2025. As such, NOVAGOLD's pro-rata share of Donlin Gold's $43 million budget and expected funding for 2025 has increased to $24 million in light of the Company's incremental 10 percent funding obligation following the June 3, 2025 closing of the transaction. Our share of funding for the Donlin Gold project in the first nine months of 2025 was $18.5 million, in line with the revised 2025 guidance.

Steady Project Advancement Through Exploration and RFPs to Select the BFS Lead By Year-End

The completion of the 18,454-meter drill program, which was expanded to support a new resource model and the advancement of the BFS, reinforces the project's long-term development strategy. This year's program, with initial drill results confirming consistent mineralization across multiple zones, including the top five standout intervals ranging from 3.77 g/t gold up to 23.49 g/t gold⁸, primarily focused on three activities: (1) grid drilling to further develop the modifying factors and input parameters and assumptions for future mine planning — 19 grid infill holes in the East ACMA grid totaling 5,079 meters, aimed at verifying short scale continuity of mineralization and improving resource confidence; (2) in-pit exploration drilling focused on enhancing geological modelling and supporting resource conversion — 24 holes totaling 10,370 meters, targeting areas of the pit containing Inferred Resources with the potential to be converted to Indicated Resources; and (3) geotechnical drilling, which was added subsequent to the transaction announcement, for pit wall stability analysis and mine design — four holes totaling 2,607 meters, including drilling on the material sites for construction of the access road from the Jungjuk port on the Kuskokwim River to Donlin Gold — 26 holes totaling 399 meters. Reclamation of all excavations from the 2025 drill campaign has been completed.

This year, the Donlin Gold program deployed a dedicated team of more than 80 people on site. Locals from 22 Y-K villages were hired to support drilling activities, logistics, and environmental monitoring, underscoring the project's role as a central economic driver in the region, as well as external contractors.

Furthermore, during the third quarter, an RFP for the BFS was issued to top-tier engineering firms with extensive expertise and experience to successfully deliver a major commission of this scale and effectively embark on an Engineering, Procurement, and Construction Management contract. Firm selection is anticipated to occur by year-end.

Engagement and Support for Environmental, Cultural, and Social Initiatives in the Y-K Region Strengthens Ties with Communities

In the third quarter of 2025, Donlin Gold expanded its outreach efforts in Alaska, including the following events:

In July, Donlin Gold hosted the Crooked Creek Traditional Council — the closest community to the project site — for a project site visit, followed by a separate project site tour in August for State of Alaska representatives and U.S. delegation staff. Attendees included State Representatives Jimmie and Kopp, State Senator Giessel, Adam Trombley (representing U.S. Senator Sullivan), Rick Whitbeck (representing U.S. Representative Begich), and Deputy Commissioner Nelson San Juan from the Alaska Department of Labor & Workforce Development. In August, Donlin Gold also hosted a trip with members of the U.S. delegation, including staff from the offices of Senator Lisa Murkowski, Senator Dan Sullivan, and former Senator Mark Begich, along with a Calista intern and Resource Development Council staff.

Over the course of the third quarter, Donlin Gold supported and participated in a wide variety of community events that celebrated cultural preservation, strengthened stakeholder relationships, and promoted the economic and social well-being of the people in the Y-K region. Those activities included, among others: Calista's Shareholder Relations Committee meetings in both Palmer and Anchorage; the village of Napaimute's annual gathering; the annual Bluegrass Festival in McGrath; Alaska Native Heritage Center's 2025 Garden Party in Anchorage; the Aniak Traditional Council Annual Fair; Kalskag's Culture Camp; Calista's Golf Tournament; the Kwethluk Church Event; and the Napaskiak Summer Festival.

Donlin Gold supported various educational programs, including Crooked Creek's Traditional Council Summer Youth Employment Program which also assists Elders, and Covenant House Alaska's Bethel Jobs for American Graduates program — a nonprofit organization dedicated to helping high school graduates successfully transition to postsecondary education and access employment opportunities.

Donlin Gold also continued to build on the progress of its aquatic habitat restoration project, which began in 2021 and seeks to improve access and habitat for resident fish in areas affected by historic placer mining. Further development and restoration of the inlet channel at Snow Gulch was carried out in the third quarter to restore natural habitat conditions in support of aquatic life.

With Federal and Most State Permits in Hand, Supporting Agencies' Efforts in Maintaining and Defending Permits

In 2024, Donlin Gold submitted the preliminary design packages for the Dam Safety Certification to the Alaska Department of Natural Resources (ADNR). Comments from ADNR are anticipated in 2025. The contracting process is underway for the detailed design package, which is anticipated to be completed by December 2026.

In State litigation, we continued to support the State agencies in defending their issuance of Donlin Gold's water rights permits, State pipeline Right-of-Way (ROW), and 401 Water Quality Certification. The cases challenging the water rights permits and pipeline ROW have been fully briefed and argued before the Alaska Supreme Court, with decisions anticipated in 2025. The Alaska Superior Court upheld ADEC's issuance of the Donlin Gold 401 Water Quality Certification on May 6, 2025, and Earthjustice filed an appeal in the Alaska Supreme Court on May 28, 2025. Briefing before the Supreme Court is scheduled to be complete in late 2025 or early 2026.

On September 30, 2024, the District Court upheld the federal agencies' analysis on two of the three issues raised in Donlin Gold's Joint Record of Decision, 404 permit, and pipeline ROW. The plaintiffs filed a request for reconsideration on one of these issues, which the Court subsequently denied. Briefing on the appropriate remedy to address the Court's decision that a hypothetical larger tailings release should have been analyzed is complete and a hearing was held May 9, 2025. On June 10, 2025, the Federal District Court issued an order on remedy, denying Earthjustice's request to vacate the permits and remanding the case to the agencies to supplement the National Environmental Policy Act (NEPA) analysis on the narrow issue regarding the release from the tailings storage facility. The Court retained jurisdiction over the case during the remand and ordered the agencies to file periodic status updates with the court.

Together, these milestones underscore the project's strong regulatory foundation, the continued defense of its permits by federal and state agencies, and its forward momentum.

NOVAGOLD Outlook

With the new ownership structure in place and the project's future in focus, we are building excellent momentum as we enter the next phase of development to maximize Donlin Gold's value proposition and exceptional leverage to gold. Our near-term catalysts include awarding the BFS contract before year-end and commencing the work shortly thereafter. We also anticipate releasing additional results from the 2025 drilling program in the coming months and embarking on an exploration program to access additional resources and identify new district-wide targets. Meanwhile, we are already gearing up to be pre-positioned to engage in discussions with various financing sources.

To support these critical activities, hiring priorities have been identified and recruitment for key roles at Donlin Gold are underway. Concurrently, we continue to assist State permitting efforts and to engage proactively with government representatives. Stakeholder outreach and investment initiatives across Alaska remain ongoing, as close cooperation with Alaska Native Corporation landowners shall continue to inform all stages of development, construction, and operation. We are steadfastly committed to transparent communication and look forward to sharing updates on major milestones in the months ahead.

In closing, allow me to take this opportunity to express our management team's sincere gratitude for the extraordinary support and loyalty that we have experienced throughout this most catalytic sequence — from existing and new shareholders to the investment community, stakeholders, and banks. The last six months broadened awareness of NOVAGOLD to new levels. And while we did not need any encouragement, this exceptional breakthrough considerably strengthened our passion to pursue the Company's goals with reinvigorated determination.

Reflecting on this pivotal period, I wish to express my heartfelt appreciation to the entire NOVAGOLD team, our Chairman, and the Board of Directors. Their unwavering dedication, insightful leadership, and diligent efforts were instrumental in successfully completing the Donlin Gold transaction and associated capital raising initiatives. With this foundation firmly in place, we are excited to move forward in partnership with our allies at Paulson to advance the Donlin Gold project — and to do so at flank speed.

Sincerely,

Gregory A. Lang

President and CEO

FINANCIAL RESULTS

Liquidity and Capital Resources

In the third quarter of 2025, cash equivalents decreased by $235.6 million, primarily due to $210.1 million paid to complete the Donlin Gold transaction, $42.0 million in net purchase of term deposits, $8.1 million in Donlin Gold funding partially offset by $26.9 million in proceeds from the exercise of an underwriter's overallotment option on the May 2025 equity offering, net of $1.4 million of issuance costs. During the first nine months of 2025, cash equivalents increased by $15.9 million primarily due to $270.8 million in proceeds from a public equity offering and concurrent private placement, net of $11.2 million of issuance costs partially offset by $210.1 million paid to complete the Donlin Gold transaction, $18.5 million in Donlin Gold funding and $8.0 million in net purchase of term deposits and corporate general and administrative costs.

Cash used in operating activities in the third quarter and first nine months of 2025 was $3.1 million and $2.6 million lower, respectively, than the comparative prior year periods. Funding of Donlin Gold was $5.2 million and $8.3 million higher in the third quarter and first nine months of 2025, respectively, due to increased site activity in 2025 than the comparative prior year periods when field work activities were minimal and due to the Company's 10 percent increased Donlin Gold funding obligation starting in the third quarter.

(in thousands of U.S. dollars)	As of August 31, 2025 $	As of May 31, 2025 $	As of August 31, 2024 $
Cash and term deposits	125,169	318,737	105,572
Total assets	345,385	329,295	114,731
Total liabilities	168,273	164,018	152,540

2025 Outlook

While the 2025 Donlin Gold budget of $43 million remains unchanged following recent project meetings held by the current Donlin Gold project owners, we expect NOVAGOLD's share of Donlin Gold 2025 funding to increase to $24 million due to NOVAGOLD's incremental 10 percent funding obligation following the June 3, 2025 closing of the Donlin Gold transaction. Also, as a result of the closing of the Donlin Gold transaction, we expect to incur higher professional fees for the year resulting in an increase of NOVAGOLD's 2025 corporate general and administrative costs to $18 million from our previous guidance of $16 million.

The updated 2025 guidance excludes transaction costs of approximately $9 million incurred during the second and third quarter of 2025 related to the Donlin Gold transaction and a working capital adjustment of approximately $1 million paid to Barrick Mining on closing, which have both been capitalized to the Company's investment in Donlin Gold along with $200 million of consideration paid.
