DONLIN GOLD 2020 Q3 UPDATE: DRILLING CONTINUES TO YIELD HIGH GRADE INTERCEPTS AND IMPROVE GEOLOGICAL MODELING
Donlin Gold
LLC,
owned
50/50
by
Barrick Gold Corp. and
Novagold
Resources Inc., has successfully completed its
2020 85-hole
drilling
program
totalling
approximately
23,400 metres.
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 per cent of the length drilled) have been received to date, of which nine were previously released to the market on Aug. 6.
Assay results show higher grades over thinner intervals compared with 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 modelling 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 modelled 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 Aug. 6, 2020, include:
-
DC20-1877 intersected 4.17 metres grading 80.6 grams per tonne gold, starting at 123.48 m drilled depth, including a subinterval 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 subinterval 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 subinterval 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 subinterval of 7.94 m grading 11.3 g/t gold, starting at 224.20 m drilled depth.
-
DC20-1886 intersected 22.12 m grading 4.7 g/t gold, starting at 158.78 m drilled depth, including a subinterval of 4.00 m grading 12.3 g/t gold, starting at 172.90 m drilled depth.
Additional significant intervals are shown in the attached table.
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 chief executive officer of Barrick. "Building on the last two decades of exploration, the results continue to highlight Donlin's world-class potential." Mr. Bristow added, "I'd like to congratulate the joint venture team, as well as thank our native corporation partners, Calista Corp. and The Kuskokwim Corp. (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 modelled. With the industry burning through reserves, and grades continuing to decline, great drill results with even higher than modelled 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 and 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, which 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.
About
Donlin Gold
LLC
Donlin Gold is an Alaska-based company owned equally by Barrick Gold U.S. Inc. and NovaGold Resources Alaska Inc., which are wholly owned subsidiaries of Barrick and Novagold, respectively.
Donlin gold is located in Alaska, the second largest gold-producing state in the U.S. With approximately 39 million ounces of gold grading 2.24 grams per tonne in the measured and indicated resource categories (100-per-cent basis) (1), Donlin gold hosts one of the largest and highest-grade undeveloped open-pit gold endowments in the world. The planned pits in which the existing resources are sited occupy only three kilometres of an eight-kilometre mineralized belt, which itself is located on less than 5 per cent of Donlin Gold's land position. Current activities at Donlin gold are focused on the drill program, optimization efforts and community outreach.

Significant intervals represent drilled intervals and not necessarily true
thickness of mineralization. Mineralized intervals meet or exceed three metres
in length above one g/t. A maximum of four metres of continuous dilution (less
than one 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 244.5 m to 251.8 m in DC20-1884, from 234.5 m to 255.4 m in DC20-1887, all
of DC20-1889, and from 188.7 m to 377.3 m in DC20-1891.
Quality assurance/quality control procedures
The QA/QC procedures for the 2020 Donlin gold drill program and sampling protocol were developed and managed by Donlin Gold LLC 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-per-cent 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-metre lengths, with a minimum length of 0.3 metre and maximum length of approximately 3.5 metres. Sampled half-core was crushed and pulverized in ALS Ltd.'s Fairbanks, Alaska, or Whitehorse, Yukon, sample preparation facilities. Pulp samples were sent to the ALS lab in Vancouver, B.C., for gold assays and multielement 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 Ltd., Boart Longyear, DGI Geoscience Inc., Rowland Engineering Consultants and Brice Engineering LLC is independent of Donlin Gold, Barrick and Novagold.
