ANCHORAGE, Alaska, Oct. 26, 2020 (GLOBE NEWSWIRE) -- Donlin Gold LLC, owned 50/50 by Barrick Gold Corporation (“Barrick”) (TSX: ABX) (NYSE: GOLD) and NOVAGOLD RESOURCES INC. (“NOVAGOLD”) (TSX, NYSE American: NG), is pleased to announce the successful completion of its 2020 85-hole drilling program totaling approximately 23,400 meters. The holes were drilled in both the ACMA and Lewis deposit areas of the Donlin Gold project.

• Assay results for the first 25 holes (representing 30% of the length drilled) have been received to date, of which nine were previously released to the market on August 6.

• Assay results show higher grades over thinner intervals compared to those predicted by previous modelling, particularly in sedimentary rocks.

• The Donlin Gold team is wrapping-up site activities with the drill core being logged, cut, sampled, and shipped to assay laboratories. Site activities are now completed.
  

Objectives of the 2020 Drill Program and Results to Date

The primary objective of the 2020 drill program, the largest such campaign at Donlin Gold since 2008, has been to validate and increase the confidence in recent geologic modeling concepts. Once complete, it is expected to drive an update of mining schedules and life of mine business plans.

Results to date continue to exceed modeled grade-thickness, with higher grades observed over narrower intervals, particularly in sedimentary rocks. Additional assay results will be reported as they become available.

• Five of the top intervals identified since the results announced on August 6, 2020 include:
  
  • DC20-1877 intersected 4.17 m grading 80.6 g/t gold, starting at 123.48 m drilled depth, including a sub interval of 3.15 m grading 106.2 g/t gold, starting at 124.50 m drilled depth;
  • DC20-1888 intersected 6.93 m grading 43.1 g/t gold, starting at 178.58 m drilled depth, including a sub interval of 3.25 m grading 90.5 g/t gold, starting at 180.26 m drilled depth;
  • DC20-1878 intersected 19.77 m grading 11.3 g/t gold, starting at 48.86 m drilled depth, including a sub interval of 7.00 m grading 25.2 g/t gold, starting at 54.86 m drilled depth;
  • DC20-1886 intersected 33.88 m grading 6.5 g/t gold, starting at 218.20 m drilled depth, including a sub interval of 7.94 m grading 11.3 g/t gold, starting at 224.20 m drilled depth; and
  • DC20-1886 intersected 22.12 m grading 4.7 g/t gold, starting at 158.78 m drilled depth, including a sub interval of 4.00 m grading 12.3 g/t gold, starting at 172.90 m drilled depth.

Statements by the Owners

With the receipt of the latest drill results, the 2020 drill program continues to advance Donlin Gold up the value chain.

“A comprehensive geological understanding of any orebody is a foundational step that few companies in the gold industry do well. With an orebody the size, scale, and quality of Donlin Gold it is of even greater importance in order for the project to successfully deliver maximum value for all our stakeholders,” said Mark Bristow, President and CEO of Barrick. “Building on the last two decades of exploration, the results continue to highlight Donlin’s world-class potential.” Bristow added: “I’d like to congratulate the Joint Venture team, as well as thank our Native Corporation partners, Calista Corporation (“Calista”) and The Kuskokwim Corporation (TKC), on successfully completing drilling despite the enormous challenges associated with operating during the COVID-19 pandemic.”

Greg Lang, NOVAGOLD’s President and CEO, said, “With the latest set of assay results, we continue to encounter intersections of higher grade mineralization than previously modeled. With the industry burning through reserves, and grades continuing to decline, great drill results with even higher than modeled grades are exciting for any mining company — and we believe that to be particularly true for Donlin Gold at this late stage of development. The data from the 2020 drill program will be incorporated into an updated model, which could be further verified with additional drilling in 2021. Understanding the optimized geological model will form the basis for determining the best approach for the development of Donlin Gold.”

Mr. Lang added, “We are proud to work in Alaska, a state where the rule of law is well established, and socially responsible and environmentally sound mine development is welcomed. As we wrap-up activities at the site for the winter, I want to thank the Donlin Gold team, that, despite the unprecedented challenges posed by COVID-19, actually completed the drilling earlier than forecast, thereby allowing us an opportunity to drill additional holes.”

COVID-19 Response & Community Engagement

To date, no employees or contractors at the Donlin Gold site have tested positive for COVID-19. With dedicated community partners in Alaska and in the Yukon-Kuskokwim (Y-K) region, who share the objective of protecting the health of Donlin Gold’s employees and contractors, a wide-ranging set of policies have been implemented at the Donlin Gold project site this year designed to mitigate the spread of COVID-19.

Donlin Gold continues to work with Calista, TKC and other key representatives in the region to respond to community needs resulting from the COVID-19 pandemic. Despite this year’s challenges, Donlin Gold has maintained community engagement programs related to environmental management, safety, training, educational, health and cultural initiatives. A few noteworthy and recent initiatives included partnering with the Association of Village Council Presidents, Orutsararmiut Native Council and the Native Village of Napaimute for the Backhaul Hazardous Waste Removal from remote villages in the Y-K region, where a total of approximately 45,000 pounds of household hazardous materials, such as large appliances, fluorescent tubes, lead acid batteries, and electronic waste was collected and shipped out of the area for proper disposal; and Donlin Gold conducted the Campfire Alaska Summer Program with support staff in 23 Y-K communities to provide distanced activities and meal programs for youth and elders.

Significant intervals represent drilled intervals and not necessarily true thickness of mineralization. Mineralized intervals meet or exceed 3 meters in length above 1 g/t. A maximum of 4 meters of continuous dilution (< 1 g/t) is permitted. Any drill intervals not depicted in this table did not meet the significant interval criteria. Assay data are not yet available from 244.5m to 251.8m in DC20-1884, from 234.5m to 255.4m in DC20-1887, all of DC20-1889, and from 188.7m to 377.3m in DC20-1891.

QA/QC Procedures

The QA/QC procedures for the 2020 Donlin Gold drill program and sampling protocol were developed and managed by Donlin Gold LLC (“Donlin Gold”) and overseen by Barrick and NOVAGOLD. The chain of custody from the drill site to the sample preparation facility was continuously monitored. All samples are HQ-diameter core. Approximately 93% core recovery has been achieved to date. Core was logged, cut, and sampled at site by Donlin Gold employees. Samples were primarily collected on two-meter lengths, with a minimum length of 0.3 meters and maximum length of approximately 3.5 meters. Sampled half-core was crushed and pulverized in ALS Limited’s Fairbanks, Alaska or Whitehorse, Yukon sample preparation facilities. Pulp samples were sent to the ALS lab in Vancouver, British Columbia for gold assays and multi-element analysis. At least 14 quality control samples (four standards, four coarse blanks, two pulp blanks, two coarse duplicates, and two pulp duplicates) were inserted into each batch of 80 samples. The review of the quality control samples did not indicate any bias or error. There are no known factors that would materially affect the accuracy or reliability of the drill program data referred to in this media release.

Downhole directional surveys were completed on all reported completed holes by both Boart Longyear drill operators and on all but one reported completed hole by DGI Geoscience Inc. technicians, and collar surveys were completed on all holes by either Rowland Engineering Consultants or Brice Engineering LLC.

Each of ALS Limited, Boart Longyear, DGI Geoscience Inc., Rowland Engineering Consultants, and Brice Engineering LLC are independent of Donlin Gold, Barrick, and NOVAGOLD.

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 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 Barrick and 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 anticipated benefits from the 2020 drill program including an improved geological model for Donlin Gold; ongoing support provided to key stakeholders including Native Corporation partners; the potential impact of the COVID-19 pandemic on the development of Donlin Gold; the potential development and construction of Donlin Gold; the sufficiency of funds to continue to advance development of Donlin Gold; perceived merit of properties; mineral reserve and resource estimates; and future share price performance of Barrick and NOVAGOLD. 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 Barrick’s and NOVAGOLD’s management expectations, 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 permits including the right-of-way lease offer for the project’s buried natural gas pipeline; the need for additional financing to explore and develop properties and availability of financing in the debt and capital markets; the outbreak of the coronavirus global pandemic (COVID-19); 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; the need for continued cooperation between Barrick and NOVAGOLD for the continued exploration, and 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 a positive construction decision will be made regarding Donlin Gold; and other risks and uncertainties disclosed in Barrick’s most recent Form 40-F/Annual Information Form on file with the SEC and Canadian provincial securities regulatory authorities and 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 Barrick and NOVAGOLD with applicable securities regulatory authorities from time to time. Copies of these filings may be obtained by visiting Barrick’s and NOVAGOLD’s Investor Relations website at www.barrick.com and www.novagold.com, respectively, or the SEC's website at www.sec.gov or at www.sedar.com. The forward-looking statements contained herein reflect the beliefs, opinions and projections of Barrick and NOVAGOLD on the date the statements are made. Barrick and NOVAGOLD assume no obligation to update the forward-looking statements of beliefs, opinions, projections, or other factors, should they change, except as required by law.

Cautionary Note to United States Investors

NOVAGOLD cautions that this media release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this media release have been prepared in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (CIM)—CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (“CIM Definition Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (SEC) Industry Guide 7 (“SEC Industry Guide 7”), and resource and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. NOVAGOLD’s disclosure concerning Reserve & Resources Estimates remains consistent with NI 43-101. Under SEC Industry Guide 7, mineralization may not be classified as a "reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. SEC Industry Guide 7 normally does not permit the inclusion of information concerning "measured mineral resources”, "indicated mineral resources” or "inferred mineral resources” or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves” under SEC Industry Guide 7 in documents filed with the SEC. Investors should also understand that "inferred mineral resources” have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Under Canadian rules, estimated "inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies except in rare cases. Disclosure of "contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves” under SEC Industry Guide 7 as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves” are also not the same as those of SEC Industry Guide 7, and reserves reported by NOVAGOLD in compliance with NI 43-101 may not qualify as "reserves” under SEC Industry Guide 7. Donlin Gold does not have known reserves, as defined under SEC Industry Guide 7. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with SEC Industry Guide 7.

On October 31, 2018, the SEC adopted a final rule (“New Final Rule”) that will replace SEC Industry Guide 7 with new disclosure requirements that are more closely aligned with current industry and global regulatory practices and standards, including NI 43-101. Companies must comply with the New Final Rule for the Company’s first fiscal year beginning on or after January 1, 2021, which for NOVAGOLD would be the fiscal year beginning December 1, 2021. The New Final Rule provides that SEC Industry Guide 7 will remain effective until all registrants are required to comply with the New Final Rule, at which time SEC Industry Guide 7 will be rescinded. While early voluntary compliance with the New Final Rule is permitted, NOVAGOLD has not elected to comply with the New Final Rule at this time.
